 9   2.1.2   A11-Registration Reply
10   The PDSN or HSGW sends this message to the PCF to acknowledge receipt of an A11-Registration
11   Request message.

12   2.1.2.1 Successful Establishment Operation
13   Upon receipt of an A11-Registration Request message with a nonzero Lifetime value, the PDSN or
14   HSGW shall respond with an A11-Registration Reply message containing the appropriate value in the
15   Code IE. For a valid A11-Registration Request message, if the PDSN or HSGW accepts
16   establishment of the A10 connection, it shall send a Registration Accepted indication (Code value
17   00H) and a non-zero Lifetime parameter value in the message. The value of the Lifetime parameter in
18   the A11-Registration Reply message shall be less or equal to the value of the Lifetime parameter
19   received in the A11-Registration Request message. Upon receiving the A11-Registration Reply
20   message, the PCF shall perform authentication and identification checks. After the message passes the
21   checks, the PCF shall stop timer Tregreq and start the Lifetime timer initialized to the value of the
22   returned Lifetime parameter.
23   In HRPD or eHRPD systems, if the A11-Registration Reply message establishes the main A10
24   connection, then the PDSN or HSGW includes the Subscriber QoS Profile, if applicable (e.g., during
25   dormant handoff). The HSGW also includes its HSGW Address Information for use in the event of a
26   subsequent inter-HSGW handoff.
27   In HRPD or eHRPD systems, when the PDSN or HSGW receives an A11-Registration Request
28   message including Additional Session Information with a non-zero Lifetime value, the PDSN
29   establishes the corresponding A10 connection(s) that do not already exist with that PCF.
30   If the PDSN or HSGW has data to send to the PCF when it receives an A11-Registration Request
31   message, the PDSN or HSGW shall include a Data Available Indication as a CVSE in the A11-
32   Registration Reply message.
33   In 1x, if the PDSN accepts a fast handoff request, the A11-Registration Reply message shall include
34   an NVSE containing the Anchor P-P Address value copied from the corresponding A11-Registration
35   Request message. If the PDSN supports fast handoff and becomes the anchor PDSN, the PDSN shall
36   include its Anchor P-P Address in an NVSE in the A11-Registration Reply message.
37   In eHRPD systems, if the A11-Registration Request message includes the Pre-Registration Indicator,
38   then any A10 connections established as a result of this A11-Registration Request message shall not
39   result in PMIP binding update.

11   If the selected PDSN or HSGW does not accept establishment of the A10 connection, it shall return
12   an A11-Registration Reply message with a reject result code in the Code IE. Upon receipt of this             Formatted: Font: Bold
13   message, the PCF shall stop timer Tregreq.                                                                   Formatted: Indent: Left: 0", Space After: 0 pt

14   The PDSN or HSGW may return an A11-Registration Reply message with result code ‘88H’
15   (Registration Denied – unknown PDSN address). When code ‘88H’ is used, an alternate PDSN or                  Formatted: Font: Not Italic
16   HSGW address is included in the A11-Registration Reply message. The address of the alternate
17   proposed PDSN or HSGW shall be returned in the Home Agent field of the A11-Registration Reply
18   message. Upon receipt of this message, the PCF shall stop timer Tregreq.
19   On receipt of an A11-Registration Reply message with code ‘88H’, the PCF shall either initiate
20   establishment of the A10 connection with the proposed PDSN or HSGW by sending a new A11-
21   Registration Request message as indicated in this section, or it shall use internal algorithms to select a
22   new PDSN or HSGW.
23   If the PCF receives a valid A11-Registration Reply message before timer Tregreq expires that
24   indicates identification mismatch (Code value 85H), the PCF may adjust the clock that it uses for
25   communication with the PDSN or HSGW, retransmit the A11-Registration Request message with a
26   newly generated Identification IE, and restart timer Tregreq.
27   On receipt of a valid A11-Registration Reply message with another result code, depending on the
28   result code, the PCF may attempt to re-try setting up the A10 connection with the same or another
29   PDSN or HSGW; refer to “PDSN Selection Algorithm” in [13].
30   The PDSN or HSGW may provide the PCF with an indication of PDSN or HSGW enabled features
31   for the A10 connection (e.g. flow control).

33   2.1.2.2 Successful Refresh Operation
34   Upon receipt of a valid A11-Registration Request message with a nonzero Lifetime value, the PDSN
35   or HSGW shall respond with an A11-Registration Reply message with an accept indication (Code
36   value 00H), including a Lifetime parameter value less or equal to the value of the received Lifetime
37   parameter and restart the Lifetime timer initialized to the value of the returned Lifetime parameter.
38   Upon receipt of this message, the PCF shall stop timer Tregreq and start the Lifetime timer initialized
39   to the value of the returned Lifetime parameter.
40   If the PCF receives a valid A11-Registration Reply message before timer Tregreq expires that
41   indicates identification mismatch (Code value 85H), the PCF may adjust the clock that it uses for
42   communication with the PDSN or HSGW, retransmit the A11-Registration Request message with a
43   newly generated Identification IE and restart timer Tregreq.

 1   On receipt of a valid A11-Registration Reply message that contains a Code other than “Registration
 2   accept” (00H) or “Identification mismatch” (85H), the PCF may resend the message with a newly
 3   generated Identification IE based on the clock it uses for communication with the PDSN or HSGW;
 4   otherwise the PCF shall initiate release of the A10 connections to this PDSN or HSGW.

 5   2.1.2.3 Successful Release Operation
 6   Upon receipt of a valid A11-Registration Request message with Lifetime field set to zero, the PDSN
 7   or HSGW shall respond with an A11-Registration Reply message with an accept indication. Upon
 8   receipt of this message, the PCF shall remove the binding record for the A10 connection and stops
 9   timer Tregreq.
10   In HRPD or eHRPD systems, upon receipt of a valid A11-Registration Request message with the
11   Lifetime value set to zero, the PDSN or eHRPD shall release all A10 connections for the AT.
12   In HRPD or eHRPD systems, when the PDSN or HSGW receives an A11-Registration Request
13   message including Additional Session Information with a non-zero Lifetime value, the PDSN or
14   eHRPD releases the A10 connections that are not referred to in the Additional Session Information.
15   If the PCF receives a valid A11-Registration Reply message before timer Tregreq expires that
16   indicates identification mismatch (Code value 85H), the PCF may adjust the clock that it uses for
17   communication with the PDSN or HSGW, retransmit the A11-Registration Request message with a
18   newly generated Identification IE and restart timer Tregreq.
19   On receipt of a valid A11-Registration Reply message that contains a Code other than “Registration
20   accept” (00H) or “Identification mismatch” (85H), the PCF may resend the message with a newly
21   generated Identification IE based on the clock it uses for communication with the PDSN or HSGW;
22   otherwise the PCF shall initiate release of the A10 connections to this PDSN or HSGW.

23   2.1.2.4 Failure Operation
24   Failure detection at the PCF: If the A11-Registration Reply message is invalid, the PCF shall discard
25   the message.
26   Failure detection at the PDSN or HSGW: None.

27   2.1.3   A11-Registration Update
28   In 1x systems, tThe PDSN sends this message to the PCF to initiate release of an A10 connection. In
29   HRPD or eHRPD systems, the PDSN or HSGW sends this message to release all A10 connections
30   associated with an AT.

31   2.1.3.1 Successful Operation
32   The PDSN may initiate release of an A10 connection by sending an A11-Registration Update
33   message to the PCF to initiate release of one A10 connection in 1x systems or all A10 connections
34   associated with an AT in HRPD or eHRPD systems. The Home Agent field in the A11-Registration
35   Update message is the PDSN Address and the Home Address is set to zero. The PCF Session
36   Identifier and other session specific information are sent within the Session Specific extension. After
37   sending this message, the PDSN starts timer Tregupd.

38   2.1.3.2 Failure Operation
39   Failure detection at the PCF: If the A11-Registration Update message is invalid, the PCF shall keep
40   the binding for the A10 connection(s) and shall not update its Lifetime timer. The PCF shall send an

 1   A11-Registration Acknowledge message indicating identification mismatch (Status value 85H) or
 2   authentication failure (Status value 83H); refer to section 2.1.4.
 3   Failure detection at the PDSN or HSGW: If the PDSN or HSGW does not receive a valid A11-
 4   Registration Acknowledge message or an A11-Registration Request message (with the Lifetime
 5   parameter set to ‘0’ and accounting related information included) before timer Tregupd expires, the
 6   PDSN or HSGW may retransmit the A11-Registration Update message with a new timestamp in the
 7   Identification information element and restart timer Tregreq a configurable number of times.
 8   If the PDSN or HSGW has not received a valid A11-Registration Acknowledge message with an
 9   update accepted status indication (Status value 00H) or an A11-Registration Request message (with
10   Lifetime parameter set to ‘0’ and accounting related information included) after a configurable
11   number of retransmissions, the PDSN or HSGW shall remove the binding record for the A10
12   connection.

13   2.1.4   A11-Registration Acknowledge
14   No changes from A.S0017-C.

15   2.2     A10-Connection Update Procedures
16   The PDSN or HSGW initiates the update of new or additional packet data session parameters on an
17   existing A10 connection with the messages described in this section.

18   2.2.1   A11-Session Update
19   The A11-Session Update message is sent from the PDSN or HSGW to the PCF to add, change, or
20   update session parameters for an A10 connection. It is also sent to update the PCF with the Anchor P-
21   P Address.

     June 16, 2008


 1   In HRPD systems, the A11-Session Update message is sent to deliver a new or updated Subscriber
 2   QoS Profile to the PCF after establishment of the main A10 connection.

 3   In HRPD or eHRPD systems, this message may also be used by the PDSN or HSGW to update the
 4   QoS for one or more specific IP flows. If there is a Flow Profile ID with the value ‘0x0000’ in the
 5   U_QoS_SUB_BLOB for an IP flow, then the AN shall inform the AT that the requested
 6   QoS_SUB_BLOB has been added but is invalid for this AN and the AT should not activate the
 7   corresponding IP flow. Otherwise upon receipt of the updated QoS, the AN shall change the granted
 8   QoS for the corresponding IP flow to the first acceptable Flow Profile ID in the list, irrespective of
 9   the contents of the subscriber QoS Profile. A Flow Profile ID shall be considered acceptable if it is
10   supported by the AN, if it matches one of the Flow Profile IDs requested by the AT, and if the call is
11   not in inter-PCF handoff. The AN shall store the updated QoS information received from the PDSN
12   or HSGW together with the personality index in use at the time the update was received. Whenever
13   the specified personality index is in use, the AN shall use the stored QoS update to grant the QoS
14   irrespective of the contents of the subscriber QoS Profile. All updated QoS information stored in the
15   AN for a given IP flow is cleared when the corresponding IP flow is set to null (refer to [10])1,
16   regardless of the personality in use.

17   Updated QoS information received from the PDSN or HSGW (via the PCF) supersedes stored
18   updated QoS information previously received from the PDSN or HSGW or from another AN (via
19   A13 or A16).

20   In HRPD or eHRPD systems, this message is also used to release one or more IP flows by setting the
21   FlowProfile ID value to ‘0x0000’ in the Forward/Reverse Updated QoS Sub-BLOB for the IP flow
22   that the PDSN or HSGW wants to release. The PDSN or HSGW should not use this procedure for
23   flow ID FFH.

24   2.2.1.1 Successful Operation
25   The PDSN may update session parameters of an A10 connection, or the Anchor P-P Address, or the
26   Subscriber QoS Profile, or update the QoS of specific flows by sending an A11-Session Update to the
27   PCF. The Home Agent field in A11-Session Update message is the PDSN or HSGW Address and the
28   Home Address is set to zero. The PCF Session Identifier and other session specific information are
29   sent within the Session Specific Extension.
30   The A11-Session Update message includes the session parameter(s), or the Anchor P-P Address, the
31   Subscriber QoS Profile, and/or QoS Update Information in NVSE(s). In HRPD systems, the A11-
32   Session Update message includes the subscriber QoS profile and/or QoS Update Information. For
33   session parameter(s), the PCF shall update its session parameters or relay the parameters to the BS
34   according to the specified behavior for the particular parameter. The PCF shall relay the Anchor P-P
35   Address to the BS. For the Subscriber QoS Profile, the PCF shall update its Subscriber QoS Profile if
36   the packet data session is dormant or relay the parameters to the AN if the packet data session is
37   active.
38   If the A11-Session Update message includes updated QoS for one or more IP flows and the RAN
39   does not have sufficient resources available to comply with the updated QoS for all of the specified
40   flows, then the PCF may reject the A11-Session Update message by sending an A11-Session Update
41   Ack message with the Status IE set to “Update Denied – insufficient resources”.

 1   If the A11-Session Update message includes updated QoS and the RAN only has resources available
 2   to comply with the updated QoS for some of the specified flows, the PCF may respond by sending an
 3   A11-Session Update Ack message with the Status IE set to “Partial QoS updated”. The PCF informs
 4   the PDSN or HSGW of which QoS updates were accepted and which were rejected using the IP flow
 5   mapping update procedure.
 6   After sending the A11-Session Update message, the PDSN or HSGW shall start timer Tsesupd.

 7   2.2.1.2 Failure Operation
 8   Failure detection at the PCF: If the A11-Session Update message is invalid, the PCF shall not update
 9   any session parameters. The PCF shall send an A11-Session Update Acknowledge message indicating
10   identification mismatch (Status value 85H) or authentication failure (Status value 83H); refer to
11   section 2.2.2.
12   Failure detection at the PDSN or HSGW: If the PDSN or HSGW does not receive a valid A11-
13   Session Update Acknowledge message before timer Tsesupd expires, the PDSN or HSGW may
14   retransmit the A11-Session Update message with a new timestamp in the Identification information
15   element a configurable number of times to the PCF.
16   If the PDSN or HSGW has not received an A11-Session Update Acknowledge with an accept
17   indication (Status value 00H) after a configurable number of retransmissions, the PDSN or HSGW
18   shall consider the update failed and shall maintain the A10 connection.

 1   a. This element can also be used to identify the IPv4 address of an alternative PDSN or HSGW.
 2   b. This element is included if the PDSN or HSGW has data available.
 3   c. This element is used by the anchor PDSN to provide an Anchor P-P Address when the PDSN
 4      supports fast handoff.
 5   d. One or more instances of this element may be included.
 6   e. During a fast handoff, the target PDSN includes the Anchor P-P Address to indicate that the fast
 7      handoff request was accepted.
 8   f.   This element is used to send a Radio Network Packet Data Inactivity Timer (RN-PDIT) to the
 9        PCF when supported.
10   g. When an Always-on Indicator is present at the PDSN, the PDSN shall include the NVSE with an
11      Always-on indicator.
12   h. This element is used by the PDSN or HSGW to indicate that flow control is enabled for the
13      packet data service instance.
14   i.   In 1x systems, this IE contains information for the main service instance. In HRPD or eHRPD
15        systems, this IE contains information for the main service connection.
16   j.   If this message is sent to establish the main A10 connection during dormant handoff in an HRPD
17        or eHRPD system, the PDSN or HSGW shall include the NVSE with the saved Subscriber QoS
18        Profile, if any.
19   k. This IE contains information (in the Additional Session Information application type) for
20      auxiliary A10 connection(s) requested in the corresponding A11-Registration Request message.
21   l.   In HRPD or eHRPD systems with QoS, this element is included by the PDSN or HSGW when
22        this message is sent to establish the main A10 connection. It provides the PDSN or HSGW
23        ROHC channel parameter values when ROHC on SO67 is supported with ROHC in the PDSN or
24        HSGW.
25   m. This IE may be used to indicate that the PDSN or HSGW supports receiving the GRE
26      segmentation attribute in A10 GRE frames.
27   n. If this message is sent to establish the main A10 connection in an eHRPD system, the HSGW
28      shall include this IE to convey its HSGW Address Information. This information is saved in the
29      event of an inter-HSGW handoff.
30   o. In eHRPD systems, this element is included by the HSGW to provide the Target HSGW Address
31      Information when this message is sent in response to an A11-Registration Request message
32      containing the user’s APN Information. This information is used for handoff from E-UTRAN to
33      eHRPD.
34   p. In eHRPD systems, this IE contains the user’s APN Information when requested by the presence
35      of the E-UTRAN Handoff Information Request Indicator in the corresponding A11-Registration
36      Request message. This information is used for handoff from eHRPD to E-UTRAN.

 9   a. This field is set to zero by the PDSN or HSGW and ignored by the PCF.
10   b. This element is used by the PDSN to provide an RN-PDIT value to the PCF.
11   c. When an Always-on Indicator is present at the PDSN, the PDSN shall include the NVSE with an
12      Always-on indicator
13   d. This element is included by the PDSN to update the PCF with an Anchor P-P Address for fast
14      handoff.
15   e. For HRPD or eHRPD systems the MN Session Reference ID field of this IE shall be set to 00
16      01H.
17   f.    In HRPD or eHRPD systems, this IE is used when the PDSN updates QoS for one or more IP
18         flows in the specified direction. If there is a Flow Profile ID with the value ‘0x0000’ in the
19         U_QoS_SUB_BLOB for an IP flow, then the AN shall inform the AT that the requested
20         QoS_SUB_BLOB has been added but is invalid for this AN and the AT should not activate the
21         corresponding IP flow. Otherwise upon receipt of the updated QoS, the AN shall change the
22         granted QoS for the corresponding IP flow to the first acceptable Flow Profile ID in the list,
23         irrespective of the contents of the subscriber QoS Profile. A Flow Profile ID shall be considered
24         acceptable if it is supported by the AN, if it matches one of the Flow Profile IDs requested by the
25         AT, and if the call is not in inter-PCF handoff. The target AN shall store the updated QoS lists
