    LS to GSMA IREG Packeting WP

    Author: NTT DOCOMO / Itsuma

    Reply from GSMA IREG PACKET in C1-111669.



    XCAP (Ut interface for MMTEL as described in
    TS24.623, TS24.173 and RFC4825) is a protocol
    used "for the purpose of manipulating PSTN/ISDN
    Simulation services data". This protocol has been
    recently agreed to be a part of VoLTE Profile (IR.92)
    in GSMA.



    XCAP is transported over Ut interface using HTTP,
    and thus requires HTTP URI for the XCAP server
    (XCAP Root) discovery. This URI for is called
    XCAP Root URI, as defined in RFC4825.



    To guarantee secure Inter-PLMN DNS resolution for
    XCAP, the following issues has been discussed and
    agreed:



            DNS for XCAP is completely separate from
    the DNS on the Internet. This is purposely done to
    add an extra layer of security to the involved
    networks.



            To send XCAP over based on GSMA
9
     requirements as specified in GSMA PRD IR.67, the
     DNS for XCAP requires the use of "well-known"
     FQDN for XCAP Root URI, given the fact that
     GSMA currently requires the use of standardized
     FQDN for the inter-PLMN DNS resolution in any
     service.



     As a result, CT4 agreed on the Change Request for
     XCAP Root URI FQDN as attached.

     A new subdomain 'ipx' is proposed to support the
     case where DNS is resolved by UE and/or network
     node. The agreed service id string is 'utmmtel', in
     order to express XCAP over Ut interface for
     MMTEL.



     Although the CR was agreed, there was a question
     raised in the meeting such that:

     - Can XCAP Root URI not utilize the existing
     '3gppnetwork.org' without any sub-domain?

     - Currently '3gppnetworks.org' is used by the
     network node only but is it possible to extend the
     applicability of this domain to UE?



     Action to GSMA IREG Packeting WP:

     CT4 kindly asks GSMA IREG Packeting WP to
     discuss the two alternatives described above, and
     inform the result to CT4 and TSG CT.

     During LTE device testing, an excessively high
     update activity on the EF_EPSNSC (EPS NAS
     Security Context) File in the USIM – device interface
     was observed. Depending on the usage, the UICC
     memory may be worn out in a few months. CT6
     would like to know if it is possible to reduce the
     number of UICC writing by stating in SA3
     specification TS 33.401 that the update of NAS
     security context into UICC shall occur only on a
     state transition to EMM-DEREGISTERED. It is not
     expected that using the ME memory would solve the
     issue.



     A) Problem description, details:

     Depending on the device tested, the average update
     frequency varied from 1 update every 10 sec to 1
     update every 4 min. Such a high update activity will
     stress the UICC memory and shorten the UICC life
     cycle. The typical amount of write/erase cycle
     supported by silicon manufacturers for flash
     memory is 100.000 write/erase cycles over a typical
     UICC lifetime. Although the file EF_EPSNSC has
     been specified as an "Update activity High" file in TS
     31.102, such an excessive amount of updates is far
     beyond expectation and the UICC memory may be
     worn out in a few months.



     The file EF_EPSNSC defined in TS 31.102 contains
     the ASME key, Uplink and Downlink NAS count, and
     the Key Set Identifier. The update to EF_EPSNSC
     occurs each time one of the NAS counters (uplink or

13
     downlink) is incremented. EF_EPSNSC is also
     updated to mark the NAS security context as invalid.
     According to TS 33.401 clause 7.2.6, the update
     shall be performed for each state transition from
     ECM-CONNECTED to ECM-IDLE, from ECM-IDLE
     to ECM-CONNECTED, and from EMM-
     REGISTERED to EMM-DEREGISTERED.



     B) EMM parameter storage

     According to Annex C of TS 24.301, EMM
     parameters can be stored either in the ME or in the
     USIM. The benefit to store the EMM parameters in
     the USIM is that a new complete EPS AKA run is
     not required in case of plastic roaming. This speeds
     up the network access, saves authentication vectors
     and decreases the signalling between the MME and
     HSS after a power cycle.

     Since the CT1 specifications implement a security
     requirement from SA3, it seems necessary to
     update TS 33.401 before modifying the EMM
     parameter storage procedures in TS 24.301.



     C) One proposed way forward

     The benefit to store EMM parameters in USIM has
     been confirmed by SA1 in the past (see S1-083468,
     S1-083170). A way to solve the issue is to clarify
     that the EPS NAS Security Context shall be updated
     by the ME only on a state transition from any state
     to EMM-DEREGISTERED. This would reduce the

14
                                                                      amount of write operations to an acceptable level.

                                                                      As a consequence, the NAS Security Context stored
                                                                      in the UE will lose synchronization with the values
                                                                      stored in the network. CT6 would like to know if
                                                                      such a consequence is acceptable from SA3's
                                                                      standpoint.

                                                                      The benefit of EMM parameter storage in USIM
                                                                      would still be present, as the ME will move to an
                                                                      EMM-DEREGISTERED state at power-off, and will
                                                                      update the NAS security context in the USIM.

                                                                      It is essential that a change to TS 33.401 to address

     3GPP TSG GERAN WG2 (GERAN2) thanks CT1
     for their LS on issues related to deployment of CBS
     service in a shared network.



     GERAN2 agrees with 3GPP TSG CT WG1 that
     solution 2 (one dedicated CBC per CN operator)
     would add complexity in the MOCN case and should
     therefore be avoided.



     GERAN2 would also like to inform 3GPP TSG CT
     WG1 that both scenarios 1a & 1b are feasible from
     GERAN perspective. Additionally, GERAN2 shares
     3GPP TSG RAN WG3 opinion (Reply LS R3-
     110010) that the choice between proposed
     scenarios 1a & 1b (i.e. whether a common CBC is
     operated either by the operator of the shared RAN
     or by one of the CN operators based on “pre
     agreements”) should be kept out of 3GPP
     Standards scope and left to operators decision.

                                             22
     made in order to align the RAN2 specifications:



     1) For membership check during UE based
        mobility (i.e. IDLE and UMTS PCH), the UE
        shall consider the CSG-Id part of all broadcast
        PLMN's.



         Note that suitability check will only consider
         rPLMN/sPLMN/ePLMN as indicated already in
         25.304/36.304, i.e. only if
         (rPLMN/sPLMN/ePLMN, CSG-Id) is in the
         whitelist, the cell will be considered suitable.



     2) In connected mode when the UE is asked to
        report member/non member, the UE considers
        itself member only if the rPLMN is broadcast by
        cell and (rPLMN, CSG-Id) is in the UE's
        whitelist.



     3) Proximity should only be reported if there is a
        possibility that a UE membership check could
        indicate "member".



     RAN2 is aware that RAN sharing is not supported in
     the CN. RAN2 would like to confirm with CT1
     whether the above agreements are aligned with
     CT1 understanding and specifications and whether
     any issues may arise from the agreements for the
     non-RAN sharing case. It remains to be seen
     whether the above will also work for the RAN

                                                    In the LS R2-111802/S2-111205 [1] from SA2, three
                                                    potential problems are identified with the
                                                    implementation of PS domain Core Network
                                                    Overload control. RAN2 thank SA2 for their studies
                                                    and herein provides answers to them respectively.



                                                    1) The first problem is treating the scenario where
                                                    section 6.9.1 of TS 23.060 requires the UE to initiate
                                                    the CS domain Location Update and then initiate the
                                                    PS domain Routeing Area Update when using NMO
                                                    II. It is noted that when coupled with some specific
                                                    issues most RA Updates are sent on an RRC
                                                    connection that was established for the CS domain.
                                                    Therefore SA2 asked how the RNC respond
                                                    adequately to PS domain Overload control
                                                    instructions sent over Iu-ps (or entered via O&M).


                                                    We believe that this could be solved by adding
                                                    extended wait timer to the Signaling Connection
                                                    Release message [2].In the beginning, the RRC
                                                    connection is established for CS domain and the
                                                    LAU is initiated. With the overload notification from
                                                    SGSN available at RNC, the RNC could reject the
                                                    connection to the PS domain by replying the
                                                    Signaling Connection Release message indicating
                                                    PS domain wherein the extended waittime could
                                                    prevent the UE from access reattempts for a long
                                                    time period. With this approach, the connection on
                                                    CS domain is not affected and could resume as it is.


                                               25
     2) The second problem is regarding to the scenario
     that RRC Connection is normally opened with a CS
     domain TMSI in the RRC Connection Request
     message (section 8.5.1 of TS 25.331) when a
     standalone RA update is performed. In this case,
     RNC has to wait for the Initial Direct Transfer
     message to reject the PS domain RRC Connection.
     Therefore, SA 2 wonder whether RAN 2 is
     interested in updating the UMTS RRC specification
     so that PS domain accesses use the PS domain P-
     TMSI in the RRC Connection Request message?
     We admit that the clarification on using the PS
     domain P-TMSI in the RRC Connection Request
     helps reduces the RRC message exchange
     somehow and allows RNC to reject the connection
     at the earliest moment. But RAN2 considers this an
     optimisation which is not urgent because nothing is
     broken. The extended wait timer included in RRC
     Connection Reject, Release and Signaling
     connection release could well solve the problem.


     3) The third problem refers to the handling of pre-
     Release 6 UEs. SA 2 note that in the pre-Release 6
     RRC specifications, the RRC Connection Request
     did not contain the CN domain indicator when the
     UE was performing LAU or RAU. So SA 2 imagine
     that the RNC functionality that handles issues (1)
     and (2) above, also needs to function correctly with
     mobiles that are pre-Rel 6/have not implemented
     this part of the Rel 6 specifications.


     For Pre-Release 6 UEs, though the CN domain
     indicator is unavailable, Initial Direct transfer and
26
                                                                  Signaling Connection release could still be applied
                                                                  to manage domain specific signalling control.
                                                                  Therefore, we sees no need to have specific
                                                                  handling for pre-Rel-6 MTC devices.

                                                                     RAN5 is developing conformance test specification
                                                                     as per WI "CT1 aspects of IMS emergency calls
                                                                     over GPRS & EPS". One of the test scenarios
                                                                     considered verifies that the UE is capable of storing

                                                28
     up to 10 Local Emergency Numbers provided by the
     network.



     As per the TS 24.301, the Local Emergency
     Numbers are to be provided by the network in the IE
     "Emergency number list" which is specified in TS
     24.008, clause 10.5.3.13. When examining this IE,
     RAN5 noticed that the way the IE is specified differs
     to specification of other IEs that carry a list of
     objects.



     For example:



     Figure 10.5.84c/3GPP TS 24.008 Emergency
     Number List information element specifies fields for
     2 numbers namely "1st Emergency Number" and
       nd
     "2 Emergency Number".



     Figure 10.5.13/3GPP TS 24.008 PLMN List
     information element specifies fields for PLMN 1 and
     PLMN 15 with an "empty" filed in between to
     represent the rest of the PLMNs (i.e. PLMN 2 -
     PLMN 14)



     The above led RAN5 to the concern if the
     Emergency Number List information element indeed
     could carry 10 or more numbers (as long as the
     overall maximum length of 50 octets is not
     exceeded) or it is specified to carry 2 numbers only.

                                                                         Despite of this concern, based on the TS 24.301
                                                                         specification, RAN5 decided to make the
                                                                         assumption that the Emergency Number List
                                                                         information element indeed could carry 10 numbers.

                                                                         If the answer is "Yes", RAN5 would like kindly to ask

     with cause#10 and TAU reject (both normal and
     combined) with causes #9, #10 and 40 for Rel8
     UEs. RAN5 has decided to allow both options in the
     test cases covering these scenarios as a temporary
     solution and to seek guidance from CT1 on
     expected UE behaviour. The solution to allow both
     behaviour has been implemented as per of CR R5-
     110775.



     The following positions were expressed during
     RAN5 discussion:



         - It has been pointed out that some commercial
         NWs and UE manufacturers have already
         implemented the possibility to re-use the NAS
         signalling for these use cases and the fact to
         remove this possibility would lead to user
         experiencing longer out of service experience,
         more signalling (release and establishment of
         radio bearer) and processing in the UE (e.g. cell
         selection). Therefore RAN5 should consider
         both implementation since Rel-8 commercial
         NWs were already launched and UE were
         already supplied..



         - It was highlighted that the possibility to use the
         existing NAS Signalling connection could lead to
         a race condition in which the UE attempts to
         use the existing NAS signalling connection to
         perform the re-attach procedure while the
         network initiates RRC Connection Release.



     RAN5 would like to confirm with CT1 if the

                                                                        connection to re-attach is compliant with the core

     Question to SA2: Single Radio VCC:



     CT1 has been discussing how the SCC AS and the
     SRVCC capable UE can get the same view as to
     whether a session is subject to SRVCC, i.e. is
     anchored in the SCC AS. Two options have been
     discussed, but no agreement has been made. The
     proposals are:



     1. To indicate this explicitly in signalling (e.g. in the
     signalling from the SCC AS towards the UE) that a
     session is subject to SRVCC, i.e. anchored in the
     SCC AS



     2. To let the UE derive the information that a
     session is subject to SRVCC (i.e. that it has been
     anchored) from existing signalling, i.e. the SC UE
     learns that a session is subject for SRVCC from the
     fact that it is an audio session and the audio is
     transported over a PS bearer with QCI-1 (or with
     traffic class="conversational" and source statistics
     descriptor ="speech")



     Do you believe that 2) is possible or do we need a
     solution based on 1)?



     Answer:

36
     SA2 believes that solution 2) is possible and is
     already supported by existing specifications. When
     SRVCC is enabled, QCI-1 (or with traffic
     class="conversational" and source statistics
     descriptor ="speech") can only be used for IMS
     speech sessions subject to SRVCC according to TS
     23.216. SA2 is reviewing the need to further clarify
     the above solution in the relevant specifications
     through rel.10. SA2 wants to clarify also that the text
     in sections 4.2 and 4.3 of TS 23.216:



     For facilitating session transfer (SRVCC) of the
     voice component to the CS domain, the IMS
     multimedia telephony sessions needs to be
     anchored in the IMS.



     is not a normative requirement and should not be
     interpreted that only MMTEL sessions will be
     anchored in IMS/SCC AS. In fact any sessions that
     will be subject to SRVCC based on HPLMN
     operator policy determined by iFCs need to be
     anchored on IMS/SCC AS.



     Question to SA2: Dual Radio VCC:



     CT1 have been discussing similar issues with dual
     radio VCC (DRVCC).



     • Does the SC UE need to get an explicit indication
     that the session has been anchored in the SCC AS;


37
                                                                     or

                                                                     • Can the SC UE deduce whether the session has
                                                                     been anchored in the SCC AS from the
                                                                     characteristics of the session?



                                                                     Answer:

                                                                     SA2 believes that an explicit indication is not
                                                                     needed even in the case of Dual Radio VCC since
                                                                     the UE initiates the session transfer and the UE can
                                                                     assume that the relevant sessions will be anchored

                                                                       CS resource happens in another case i.e. when
                                                                       the UE moves from GERAN/UTRAN with Gs
                                                                       association (i.e. NMO I) to E-UTRAN without
                                                                       SGs association (e.g. provision VoIMS). It is
                                                                       because that the MSC/VLR considers the UE is

                                              40
     still IMSI attached (i.e. neither establish SGs
     association nor receive Cancel Location
     message) and the "implicit detach timer" stops
     due to the activated Gs association.

     But, SA2 thinks it is not necessary to solve this
     problem due to the reasons as follows:

     a)   It happens only when the Gs association
          has been established, but Gs interface is
          rarely deployed in the real world.

     b)   According to the current principle, the
          MSC/VLR is allowed to keep the CS
          context of the detached UE for a while, so
          that it can be reused later without
          accessing the HLR when the UE returns
          back to GERAN/UTRAN and registers into
          the same MSC/VLR.

     c)   T-ADS functionality can be used to avoid
          routing the mobile terminated service to
          the MSC/VLR, e.g. provide VoIMS over
          LTE.

     d)   Even the MSC/VLR receives mobile
          terminated service request (e.g. IAM
          message), it pages via Gs interface firstly
          and then receives paging reject message
          ("implicit detach timer" restarts). According
          to the paging failure handing mechanism
          specified in TS 29.018, the MSC/VLR is
          not required to page the UE via A/Iu
          interface. In this case, the mobile
          terminated service may fail, but it is not a
          big problem considering bullet c.

     e)   In addition the MSC can use existing
          mechanisms to purge long term inactive

                                                                        initiate the CS domain Location Update and then
                                                                        initiate the PS domain Routeing Area Update when
                                                                        using NMO II. When coupled with issues such as:
                                                                            -    many networks using NMO II;
                                                                            -    LA boundaries are always RA boundaries;

                                                 42
         -   the number of RAs per LA is generally low
             (e.g. one RA per LA); and
         -   the CS domain is generally used for MO-
             SMS, and (unfortunately) might remain in
             use, even in MTC devices;
         then it can be seen that most RA Updates are
         sent on an RRC connection that was
         established for the CS domain.
     This raises the question:
             how does the RNC respond adequately to
             PS domain Overload control instructions
             sent over Iu-ps (or entered via O+M)?
     The necessary RNC functionality might rely on the
     RA Update procedure’s “UE abnormal case”
     functionality specified in TS 24.008 (e.g. in which
     the UE retransmits the RA Update if no reply is
     received from the network).
     SA 2 believes that it will be beneficial if any such
     dependency of RAN functionality to CT
     specifications is documented somewhere (e.g. so
     that CT 1 future changes to TS 24.008 do not have
     unexpected consequences on the RNC’s CN
     overload control features)


     2) When a standalone RA update is performed, the
     RRC connection is normally opened with a CS
     domain TMSI in the RRC Connection Request
     message (section 8.5.1 of TS 25.331).
     When using “Iu-flex” on the PS domain, and say,
     only one SGSN in the pool is congested, this seems
     to inhibit the ability of the RNC to Reject the PS
     domain RRC Connection and the RNC has to wait
     for the Initial Direct Transfer message. Given that
     the NAS protocols tend to repeat unanswered NAS
     requests 4 times, SA 2 wonder whether RAN 2 is
43
     interested in updating the UMTS RRC specification
     so that PS domain accesses use the PS domain P-
     TMSI in the RRC Connection Request message?


     3) Networks have to cope with mobiles of all
     releases. SA 2 note that in the pre-Release 6 RRC
     specifications, the RRC Connection Request did not
     contain the CN domain indicator when the UE was
     performing LAU or RAU.
     SA 2 imagine that the RNC functionality that
     handles issues (1) and (2) above, also needs to
     function correctly with mobiles that are pre-Rel
     6/have not implemented this part of the Rel 6
     specifications.



     Actions
     To RAN 2, RAN 3:
     SA 2 kindly asks RAN 2 and RAN 3 to consider the
     above issues and to:

     -       inform SA 2 and CT 1 as to how the RNC
             can handle PS domain CN node congestion
             in the above 3 situations; and

     -     indicate any preference on how any inter-
     TSG specification dependencies are documented.



     To CT 1:
     SA 2 kindly asks CT 1 to note the above questions
                and to be ready to assist RAN 2 and

                                          SA2 answer to RAN2's queries on Wait Timer for
                                          each CN domain. SA2 left a RAN2 question to CT1
                                          to answer.

                                          ========= extract from LS ============

                                          Question a) Does the Extended Wait Timer in
                                          NAS run per CN domain?

                                          Answer A) Yes. The CS domain and PS domain
                                                    are expected to experience
                                                    independent (over)load situations.
                                                    Hence SA2 expect that the Extended
                                                    Wait Timer is specific to the CN
                                                    domain.
                                          Question b) Is it expected that in case a
                                          signalling connection is already established
                                          with one CN domain, and (during the
                                          established RRC connection) a NAS-requested
                                          signalling connection establishment to the other
                                          CN domain is rejected (due to high CN load), the
                                          signalling connection to the first CN domain
                                          remains, while the signalling connection with
                                          the second CN domain is rejected with Extended
                                          Wait Timer?

                                          Answer B) Yes, it is expected that the
                                                    communication with the non-congested
                                                    domain is not interrupted (this helps
                                                    avoid an overload in one domain
                                                    leading to increased load in the other
                                                    domain).



                                          Question C) In case that a RRC Connection
                                          Release is sent to the UE including the

                                     51

                                                                      indication from the AS of the concerned CN
                                                                      domain, or is NAS able to decide this based on
                                                                      NAS-internal CN domain status information?

                                                                      Answer C) SA 2 believes that this question is best

                                                                      back-off timer value via PCRF).”


                                                52
     SA2#84 revisited this issue, and agreed that both
     APN congestion and Low Access Priority Indicators
     are per PDN connection. Decisions regarding the
     dedicated bearer handling for the GTP case do not
     require PCC impacts in order to provide equivalent
     PMIP support for the 2 cases raised by the CT3 LS.



     The LAPI is used by the network for congestion
     control at resource allocation procedure, e.g. PDN
     connection establishment. APN based congestion
     control is only specified at PDN level as it is agreed
     in CT4.



     1) APN Congestion (Backoff Timer and
        associated APN congestion cause value)



     The agreed APN based congestion control solution
     is per PDN connection.



     SA2 understanding is that the following applies:

         -      For GTP case the backoff timer is only
                sent from PGW to SGW/MME at Create
                Session Response (with rejection code) ;

         -      There is no bearer level backoff timer ;

         -      Sending the backoff timer and cause (i.e.
                APN congestion) in PMIP PBA message
                would reflect the same level of
                functionality as specified for GTP;

53
     Therefore the backoff timer and APN Congestion
     Cause value should be carried on-path within PMIP
     signalling (i.e. PBA) without impacting PCC
     functions and associated CT3/CT4 specifications.



     However, SA2 is aware that CT1 have agreed SM
     Back-off timer has been introduced to UE requested
     resource modification messages. It is SA2's
     understanding that this functionality can remain in
     Rel-10, and therefore the above agreement should
     not bring additional impact to the NAS
     specifications.



     2) Low Access Priority Indicator



     The main usage of this parameter is to support a
     congestion decision in the node (e.g. MME/SGSN,
     SGW, PGW) when a mobility protocol message
     (e.g. NAS, GTP, PMIP) contains a low access
     priority indicator provided by the UE triggers
     allocation of network resources. The nodes
     (MME/SGSN, SGW, PGW) base the decision on
     how to handle the request from a congestion
     perspective based on the message content (i.e.
     presence of LAPI) in the received mobility protocol
     message. The primary use case is for the indicator
     is to take early congestion decision in the
     SGSN/MME. It can also provides some purpose in

54
     the SGW/PGW.



     SA2 understanding is that the following approach
     applies for the PMIP case:

         -     The indicator is applicable per PDN
               connection and is common to all bearers
               per PDN connection

         -     The indicator shall be sent in the PMIP
               PBU at the establishment of the PDN
               connection

                 o   This allows the PGW in an overload
                     condition upon receiving the PBU
                     message to reject the request
                     immediately without waiting for
                     PCRF interaction.

                 o   This allows the PGW to store the
                     indicator as per the received PBU.
                     The applicability of the stored
                     indicator in this release is solely for
                     the purpose of inclusion in charging
                     records.

         -     The SGW can perform congestion control
               at bearer level based on the received
               indicator from MME/SGSN.

         -     There is no bearer concept in the PMIP
               interface, so there is no need to trigger a
               PMIP message at bearer procedure.

         -     Creating a dedicated bearer will not need
               resources at the PMIP interface in the
               PGW. Therefore there is no specific
               PGW overload protection use case to be
               supported for the PMIP message
55
               interface at the bearer level.



     SA2 believes the above is a workable approach for
     handling of NIMTC for PMIP and that this can be
     achieved without PCC impact.

     At SA3 #63 a contribution was presented which
     proposed to remove the limit of maximum number
     of IKEv2 SAs per APN from one UE in case of
     tunnel authentication in TS 33.234 (I-WLAN) and TS
     33.402 (Non-3GPP access to EPC), see attached
     S3-110480. The reason for removing the limit is that
     the underlying fraud case, where a USIM/UICC is
     re-used by several devices in WLAN UE split
     scenario in order to access 3GPP network, is no
     longer considered to be practically valid. This is
     because the limit can be circumvented by a modern
     mobile phone (or e.g. laptop) which can act as NAT
     and WLAN AP and thereby offer its PDN connection
     to be used by other devices connected to it.
     Due to the above reasons it was discussed in SA3
     to remove the limit from their specifications.
     However, it was commented in the meeting that
     there can be other than security reasons, e.g. load
     controlling, for limiting the maximum number of
     IKEv2 SAs from one UE. Therefore SA3 would like
     to ask advice from SA2 and CT1 on the following
     questions:
            Whether there is a limit for maximum
             number of IKEv2 SAs from one UE per APN
             (or W-APN in case of I-WLAN) for non-
             security reasons? Especially is there such
             limit per (e)PDG?
            Whether there is a limit for maximum
             number of IKEv2 SAs from one UE to
             different APNs (or W-APN in case of I-
             WLAN) for non-security reasons?

            Whether such limit(s) should be specified in
             3GPP specifications, e.g. in SA2
             specifications, or if they are left out of
             standardization?

                                                                  gives the understanding that in case of multiple
                                                                  PDN connections from a UE to the same APN, an
                                                                  IKEv2 SA is established for each PDN connection
                                                                  for that APN. In SA3 view this is not needed for
                                                                  security reasons since one IKEv2 SA per APN
                                                                  would be enough and IPsec child SAs could be
                                                                  created for the PDN connections. It was also

                                                                  Therefore SA3 would like to ask SA2 and CT1:

                                                                  ========== extract from LS ============

                                                                  There are many cases in UTRAN and GERAN
                                                                  where there may be a mismatch between the UE
                                                                  and the network w.r.t. the keys used for integrity
                                                                  protection (when applicable) and ciphering. For
                                                                  example, assume the UE runs a Location Area

                                              60
     Update procedure that includes an AKA and a TMSI
     re-allocation procedure and where there is a change
     of MSCs. If the connection between the UE and the
     network breaks between the successful AKA
     procedure and the TMSI re-allocation procedure,
     the keys stored on the SIM or USIM will differ from
     the keys stored in the network. Similarly, in case an
     SRVCC handover fails after the handover-complete
     sent from the target BSS/RNS to the target MSC,
     but before the TMSI re-allocation procedure, there
     will be different keys stored in the USIM or SIM and
     compared to what is stored in the network. There
     are similar cases in the pure packet switched
     domain.



     A result of such mismatch is that for UTRAN, the
     security mode control procedure will fail since the
     UE will discard the security mode command (and
     retransmissions thereof) sent by the network due to
     failing MAC-I. In GERAN, there is no integrity
     protection, so the security mode command will be
     accepted by the UE. However, the security mode
     complete response from the UE to the network will
     be ciphered using the incorrect key, so the network
     will not be able to decrypt it correctly. In either case,
     a mismatch of keys will cause abnormal conditions
     for the security mode control procedure.
     Mismatches will possibly also create problems in
     other situations.



     SA3 assumes that the stage 3 specifications
     provide sufficient detail to be able to implement a
     way to recover from abnormal situations like these.
     However, SA3 would like to request clarification on
     the following:

                                                                  move the requirement to Rel-11.




                                                                  SA3 would like to thank SA1 and CT1 for their LSs
                                                                  S3-110335/S1-110422 and S3-110327/C1-111155
                                                                  respectively.
                                                                  In their LS S3-110335/S1-110422, SA1 indicated
                                            62
     that SA1 has concluded to keep the requirement
     “The network operator shall be able to restrict the
     use of a USIM to specific MEs/MTC Devices” in the
     Release 10 version of TS 22.368 since CT6 had
     indicated that CT6 could implement this
     requirement in Release 10.
     In their meeting #63, SA3 discussed a network
     based solution for meeting the above requirement,
     and during the discussion security concerns were
     raised. Based on the discussion SA3 concluded that
     security implications and requirements for both
     terminal and network based solutions should be
     further assessed by SA3 before agreeing on any
     solution. SA3 intends to assess the security
     implications and requirements in Rel-11 timeframe.
     Therefore, SA3 would like to suggest that the
     requirement “The network operator shall be able to
     restrict the use of a USIM to specific MEs/MTC
     Devices” be moved to Rel-11, and that work on
     possible solutions to meet this requirement should
     be consequently conducted in Rel-11.
     In addition, SA3 would like ask CT6 questions in
     order to better understand the solutions CT6 is
     working on.
     Question 1: Will the solutions discussed in CT6
     allow restricting the use of a USIM to one ME/MTC
     Device or more than one MEs/MTC Devices,
     especially to a large number of MEs/MTC devices?
     Question 2: How is the operator able to enforce the
     restriction in CT6 solutions, or is the enforcement
     done only on the device?

                                                                             1. Overall Description:

                                                                             During SA4#64, SA4 discussed how to set the b=AS
                                                                             bandwidth parameter and possibly the b=TIAS
                                                                             bandwidth parameter for speech and video. SA4
                                               65
     specifications contain recommendations for how to
     set the b=AS parameter, defined as application-
     specific maximum bandwidth, by the terminal for
     particular codecs, but operators can influence the
     terminal behaviour by supplying other values as
     management objects to the terminal. SA4
     specifications do not yet contain recommendations
     for b=TIAS bandwidth values, which is defined as
     transport independent application-specific maximum
     bandwidth.



     Annex B of TS 26.236 introduces examples to
     compute b=AS for voice and video codecs. In the
     case of video, b=AS is computed assuming a fixed
     media bit-rate and a fixed amount of encoded video
     data in bytes per packet, regardless of the frame
     type, i.e., independent or predicted. Since video
     encoder controls the quantizer or frame rate, to
     reduce the fluctuation of bit-rate, b=AS in this
     definition can be considered as the average media
     bit-rate plus RTP/UDP/IP headers.



     In the case of voice, the output bit-rate of AMR or
     AMR-WB encoder fluctuates depending on voice
     activity, i.e., ranging from speech frame, SID, and
     no transmission. The method in TS 26.236 to
     compute b=AS for AMR assumes one speech frame
     encapsulated into an RTP packet in bandwidth-
     efficient mode. In this definition, b=AS can be
     considered as the maximum media bit-rate (not
     taking into account the reduction due to speech
     pauses) plus RTP/UDP/IP headers. In Annex A of
66
     TS 26.114, b=AS values computed assuming this
     method, but in octet-aligned mode, are included.
     Detailed procedures to compute b=AS for AMR and
     AMR-WB can be found in the attachment.




     2. Discussion:

     Concerns were raised by some companies that the
     answerer could interpret b=AS differently than
     intended by the offerer and thus send undesired
     media:



               For video, as long as the offered b=AS is
     allowed by service policy, the highest quality codec
     supported by both the offerer and the answerer is
     likely to be selected. In other words, b=AS is unlikely
     to impact the selection of video codec, with enough
     capability at the offerer and the answerer.



              However, voice codecs have different bit-
     rate ranges and in case the offerer and the
     answerer apply different methods to compute b=AS,
     session negotiation may result in configurations not
     preferred by the offerer or the answerer. For
     example, the offerer may compute b=AS based on
     the maximum bit-rate assumptions as in TS 26.236
     while the answerer calculates b=AS assuming
     average bit-rate (taking into account reduction due
     to speech pauses) plus some margin to avoid
     overflow. In this case, a b=AS value may be
     understood by the offerer and the answerer as
     different codec modes.

67
     SA4 discussed if the b=AS value could be set taking
     into account the statistical saving effects of speech
     pauses (b=AS recommendations in SA4
     specifications currently do not take into account
     these effects). It was pointed out that since b=AS is
     mapped to MBR, computation of b=AS for voice as
     in TS 26.236 might over-reserve the resource and
     have an impact on VoIP capacity, especially when
     MBR=GBR. However, several companies
     expressed the opinion that PCC would expect b=AS
     values not taking those effects into account. It would
     rather be up to the radio network resource
     management to take corresponding savings into
     account.



     SA4 also discussed if b=TIAS could be used to
     indicate a different bandwidth (apart from
     IP/UDP/RTP header overhead, which is not
     included in b=TIAS, but is included in b=AS), i.e., to
     restrict the maximum codec modes in this manner,
     or to correct the statistical effects described above
     possibly included in the b=AS value. However,
     concerns were raised that PCC would expect that all
     these parameters are set to corresponding values,
     as it depends on the operator and the
     implementation options which parameter is used to
     derive the reserved bandwidth, but the resulting
     bearer and reserved bandwidth should be
     appropriate for the services irrespective of these
     different options. Also, if the optional interpretation
     of codec specific information is performed by PCC,
     PCC would assign information derived in that
68
     manner a higher priority than information derived
     from b=AS and b=TIAS bandwidth information.



     Further, SA4 discussed a scenario where an MTSI
     terminal sends an offer for AMR-WB without a
     mode-set parameter, thus allowing all modes up to
     the highest mode with 23.85 kbit/s bandwidth, and
     the answer contains a mode-set parameter, e.g.,
     restricting modes to some modes up to 12.65 kbit/s.
     b=AS settings would then differ between offer and
     answer, but only the bandwidth contained in the
     answer is required in both directions, as the mode-
     set in the answer is applicable in both directions.
     Concerns were raised that PCC might then reserve
     different bandwidths for uplink and downlink based
     on the different b=AS values (While this behaviour
     is appropriate for codecs that can use different
     bandwidths in opposite directions, it is not always
     appropriate for AMR and AMR-WB).




     Actions to CT3:

     1.      SA4 would like to ask CT3 to clarify if PCC
     expects that the statistical effects of video (due to
     motion activities) and speech (due to pauses) are
     included in b=AS bandwidth values.



     2.       SA4 would like to ask CT3 to clarify if PCC
     expects that b=TIAS, b=AS and codec parameters
     are all set to corresponding values, and how PCC
     interprets those parameters.

                                                                      due to a corresponding reduction of the AMR or
                                                                      AMR-WB mode set (Will the same or different

                                                                      Actions to TSG RAN2:

     ETSI TC INT wishes to thank 3GPP CT1, CT3 and
     RAN 5 for their promotion of the 3GPP Release 8
     IMS Implementation, Deployment and testing
     workshop.

     The key goal of the workshop was to:



     • Share experiences on IMS implementation, best
     practices

     • Discuss future needs for IMS network testing

     • Evaluate testing and validation best practices, and
     techniques such as test specifications,
     interoperability events

     Please find enclosed a link to all the presentations:

     http://docbox.etsi.org/Workshop/2010/201011_IMS
     WORKSHOP/

     Following the workshop presentation and
     networking, TC INT members came to the
     conclusion that testing specifications remains an
     important business element for a successful 3GPP
     IMS Release 8 implementation.

     TC INT Would like to inform 3GPP CT1, CT3,
     RAN5 that ETSI is planning an IMS interoperability
     Event based on 3GPP R8 NNI and RCS to be held
     in Berlin from 9-16 November 2011. Interoperability
     Test Specification will include ENUM interactions
     according to IR67. TC INT is available to provide

     IREG PACKET kindly thanks 3GPP TSG CT WG4
     for the LS on XCAP Addressing (IREG LS_065 /
     Packet doc 049_017 / C4-110961).



     IREG PACKET has reviewed the document
     (CR0281 to TS23.003) provided by CT4, and would
     like to inform 3GPP CT and CT4 that IREG
     PACKET agreed to document in GSMA PRD IR.67
     the following domain name:



     ut.mnc<MNC>.mcc<MCC>.ipxuni.3gppnetwork.org



     Currently the IPX is a network providing only
     Network-to-Network Interconnect (NNI). It is only
     now that GSMA is looking at using it for User-to-
     Network Interconnect (UNI) traffic, since GSMA
     have decided to apply EPC Local Breakout for Ut
     traffic in the VoLTE roaming scenario. However, the
     label provided by CT4 ('.ipx') does not reflect this
     usage, and as such could easily be misunderstood
     to mean that it is used also for NNI
     traffic/addressing.

     Therefore, IREG Packet is of the opinion to make
     the sub-domains under “3gppnetwork.org” as easy
     to understand as possible in order to prevent any
     future misunderstandings that this one is for the UNI
     and not the NNI of the IPX.

     The 'mmtel' string in the first label has been
     removed, because GSMA recommends the use of
76
                                                               Aggregation Proxy (AP) on the HPLMN edge, which
                                                               covers any different kind of XCAP application over
                                                               Ut interface.

                                                               (extract from 23.060 v7.10.0):



                                                               “For 'MS/NW' mode, the MS evaluates for a match,
                                                               first the uplink packet filter amongst all TFTs that
                                               77
     has the smallest evaluation precedence index and,
     in case no match is found, proceeds with the
     evaluation of uplink packet filters in increasing order
     of their evaluation precedence index. This
     procedure shall be executed until a match is found,
     or all uplink packet filters have been evaluated. If a
     match is found, the PDP PDU is transmitted on the
     PDP context that is associated with the TFT of the
     matching uplink packet filter. If no match is found,
     the MS shall evaluate whether the PDP PDU
     belongs to an application for which the MS applied a
     local mapping to a PDP context. If this is the case,
     the relevant PDP context shall be used. Otherwise,
     the PDP PDU shall be sent via the PDP context that
     has not been assigned a TFT including an uplink
     packet filter. If all PDP contexts have been assigned
     a TFT including an uplink packet filter, the MS shall
     silently discard the PDP PDU.”




     In Rel-8 the concept of unidirectional bearers was
     added as follows (current 23.401 text):

     “A unidirectional EPS bearer is either associated
     with an UL TFT or a DL TFT that matches the
     unidirectional traffic flow(s) and a DL TFT or an UL
     TFT in the other direction that blocks all traffic
     flows.”



     In Rel-9 Gx was enhanced with bi-directional filters,
     i.e. pre-Rel-9 PCC rule packet filters were only

78
     unidirectional.



         1.2 Discussion



     SA2 has discussed different ways to achieve
     unidirectional bearers, including the possibility to
     remove the stage 2 description of unidirectional
     bearers or change the UEs uplink traffic mapping
     logic. However, such proposals have not been
     agreed in SA2.



     SA2#84 discussed an example of an uplink packet
     filter the GGSN/PGW could provide to the UE to
     avoid having the UE sending any useful uplink
     packets towards bearer meant to be unidirectional
     (i.e. as the network might drop those packets).

     SA2 understanding is that the packet filter would still
     need to be “valid” as UE otherwise (in case a filter
     blocking all IP flows is used) may reject the network
     request with a semantic error (extract from 24.008):

           c) Semantic errors in packet filters:

                  1) When a packet filter consists of
                     conflicting packet filter components
                     which would render the packet filter
                     ineffective, i.e. no IP packet will
                     ever fit this packet filter. How the
                     network determines a semantic
                     error in a packet filter is outside the
                     scope of the present document.

               The network shall reject the activation
               request with cause "semantic errors in

                                                                               packet filter(s)".

                                                                               The MS shall reject the activation request
                                                                               with cause "semantic errors in packet

     off Timer. For the Network Mode of Operation 1
     (combined registration) case some questions were
     raised in SA2 on the applicability of the MM Back-off
     Timer to the PS domain only or to both the PS
     domain and the CS domain. There were questions
     on the expected behaviour of the MS/UE also when
     MM Back-off timer is running.



     The following is the summary of the discussions:



     A. For the combined registration case, if the UE
        experiences general NAS congestion control,
        that should not trigger a change of its Network
        Mode of Operation. That is, it should not try to
        attach to the CS domain if it experiences PS
        domain congestion. It is SA2’s understanding
        that the current status is that if the PS domain is
        overloaded the MM Back-off timer is returned in
        the ‘reject’ message, without taking into account
        the overload status of the CS domain.
        Many companies in SA2 consider it important
        that the receipt of the MM Back-off Timer from
        the SGSN/MME should not cause the MS to
        initiate MM signalling with the CS domain.
        Stated another way, overload in the PS domain
        should not cause an increase in CS domain
        signalling and consequent overload of the CS
        domain as well.



     B. For the non-combined registration cases, the
        MM Back-off Timer received from the
        SGSN/MME should only apply to the PS
        domain.


81
     The work in 3GPP TR 23.888 on Core Network
     overload control has not been restricted to the PS
     domain only. Many MTC devices use the CS
     domain. Therefore, some companies in SA2 think
     that the congestion control features can also be
     used by the MSC as well as by the SGSN.



     The applicability of the congestion control features
     to the CS domain was informally communicated
     from SA2 to CT1 and CT4 in August 2010 by an
     email between the Chairmen. It was also more
     formally recorded in the LS from SA2 to GERAN in
     S2-104220 (attached). As noted in those
     communications, SA2 is not responsible for the
     stage 2 specifications for the CS domain.



     SA 2 kindly requests CT1 and, if necessary CT4, to
     take the above into account in the development of
     their specifications. Delegates from many
     companies in SA2 have indicated their willingness to
     discuss this jointly with CT1 and CT4, potentially in
     a conference call taking into account the strict
     timescales for the completion of NIMTC work in
     rel.10, the requirements for congestion control
     features in the CS domain.

              In their LS' GERAN3 and RAN5 mention that CT6 is
              required to clarify ways how to change the eCall
              modes dynamically, e.g. how an eCall capable UE
              which is set to eCall only mode can be reconfigured
              to permit access to additional subscribed to
              services.



              According to TS 31.102, clause 5.3.40.1 (eCall Only
              Support) an eCall capable UE is set to eCall only
              mode if the following conditions are met:

                  1) Services n°2 (FDN) and n°89 (eCall Data)
                     are available in the EFUST (TS 31.102,
                     clause 4.2.8) and

                  2) Services n°1 (FDN) is enabled in EFEST (TS
                     31.102, clause 4.2.47) and

                  3) EFFDN contains only two numbers, the eCall
                     test and the eCall reconfiguration numbers



              According to TS 31.102, clauses 5.3.40.1 and
              5.3.40.2 (eCall and Normal call support) an eCall
              capable UE is set to eCall and normal call mode if
              the following conditions are met:

                  1) Services n°4 (SDN) and n°89 (eCall Data)
                     are available in EFUST and

                  2) Service n°2 (FDN) is not available in EFUST
                     and/or service n°1 (FDN) is not enabled in

         86
                                                                     EFEST and

                                                                 3) The last two entries of EFSDN contain the
                                                                    eCall test and the eCall reconfiguration
                                                                    numbers



                                                             One way the eCall mode can be controlled is by
                                                             enabling or disabling FDN in EFEST if the services
                                                             SDN, FDN and eCall data are all indicated as
                                                             available in EFUST.



                                                             As an update of EFEST is possible via PIN2 the
                                                             enabling or disabling of FDN can be done via
                                                             different means provided by the UE, e.g. an MMI (if
                                                             available) or AT commands.



                                                             Another alternative would be to update the eCall
                                                             related EFs via Over The Air (OTA) updating (see
                                                             TS 31.115 and TS 31.116) and a consecutive
                                                             REFRESH command (see TS 31.111) which
                                                             informs the UE about this update.



                                                             CT6 hopes to have met GERAN3's and RAN5's
                                                             request for clarification and is looking forward to
                                                             further fruitful cooperation.

C1-      LS on usage of EF_ACL for EPS Network    CT6   To   Reply LS in C1-111980

                                                             TS 31.102, section 5.3.14, indicates that the ME
                                                             must check the value of the APN against a list
                                                             stored in the EF_ACL on the USIM before

                                             87
     requesting a PDP context activation from the
     network, when the corresponding service is
     available on the USIM.

     The same mechanism does not apply in the case of
     an EPS Network due to the different sequence used
     for the PDN Connectivity Request with a given APN
     value. As a result, the current specification is
     unclear and might cause different interpretations
     and behaviours.



     On an EPS network, the ME performs the ATTACH
     procedure without passing an APN value and can
     set the flag "ESM Information transfer" on. Later on,
     the ME indicates the APN value as part of the ESM
     Information Response.



     In the case where the ACL service is available on
     the USIM, TS 31.102 currently does not indicate if
     the ME needs to check if the "network provided
     APN" is contained within EF_ACL before the
     ATTACH or if the APN value that is passed later in
     the ESM Information Response is contained within
     EF_ACL or if both need to be contained within the
     EF_ACL.



     CT6 discussed to modify TS 31.102 as per the
     attached file (C6-110252), requiring the ME to check
     if the APN value that is passed later in the ESM
     Information Response is contained within EF_ACL

                                                                       CT6 asks CT1 to provide guidance on the issue

                                                                       must check to perform a PDN connection.

                                                                       138
                           the IMEI in an UPDATE.

                           There is a problem nevertheless with this due to
                           current E-CSCF specification as the IMEI is
                           expected there already in the Contact of the initial
                           INVITE (24.229 subclause 5.11.2).

                           This proposal needs further technical investigation.
                           It also needs to be clarified whether and if yes what
                           impact this handling has on common IMS.
