This Work Item intends to broaden the applicability of the MExE security
      • Click to edit Master text styles
framework and services, enabling all MExE run-time environments to operate with
a consistent MExE service environment. In particular, the new features and
      • Second level standards corresponding to different run-time
capabilities of this Work Item should allow for independence from, and re-use by,
an extremely large set of external
      • Third level
environments. It also allows for independent use of the framework for secure
software downloads without the need of a MExE run-time environment.
      • Fourth level
The main benefit of these analyses is that the extracted (and potentially
      • Fifth level
contracted) characteristics and requirements are applicable to run-time
environments identified in the future, as well as currently available run-time
environments. Other benefits include increased clarity and reduced complexity.

In fact, interest in MExE has waned, and only minor enhancements have actually been
performed.

introduces a wide distribution of data associated with the user. Several 3GPP WG
already specify some parts of the GUP in their own descriptive methods. This
       • Fourth level
distributed responsibility could lead to duplication and incompatibility amongst

    storage, ownership, access methods, and distribution and some obvious
    common objects
    •The principles of a User Profile Policy (e.g. privacy aspects)

and enforcement of rights and rules - digital rights management - is an essential
component of this distribution capability. In order for protected distribution of
         • Fifth level
content to be acceptable to consumers, it must be transparent and non-intrusive,
however security of downloadable and or streaming content must be preserved,
i.e. it must not be possible to “play” unauthorized copies.

The work is limited to stage 1 specifications; the stages 2 and 3 work is expected
to be performed by The Open Mobile Alliance.

Feature:    Wireless-LAN to UMTS interworking

There is an increasing demand for wireless "local area" access in very different
scenarios. Wireless access to Internet is provided to public users by the use of
      • existing to edit Master text styles
currently Click WLAN technology such as IEEE 802.11b. In companies,

      • Fourth level
environments with high user density and demand for higher data rates. However,
in order to provide flexible use of both technologies in these environments and to
      • Fifth level
provide mobility of services between the two technologies, it is sensible that
some degree of interworking exist between them.

A feasibility study will be performed, covering the scenarios and possible
architectures for interworking. Work will continue to produce specifications for
the service and operational requirements.

Feature:    Network sharing

The possibility of sharing part or all of the network by two or more separated
commercial entities was not considered in the initial specification work of
3GPP. •However, as e.g. a result of partnerships, the need for two or more
          Click to edit Master text styles
operators to share common network infrastructure has become an economically
      • goal. Meanwhile, changes to public network operating licence

conditions make such sharing possible from a regulatory point of view.
        • Third level
Some work has already been carried out in this area with the definition of the
        • Fourth level
equivalent PLMN concept and partly with the introduction of Iu-Flex, but there is
still the need to consolidate these activities under a coherent work plan.
        • Fifth level
This Work Item will first analyse the shortcomings of the standards in the area of
network sharing, e.g. radio network sharing, and then develop enhanced
requirements for the control of handover and cell reselection, services, charging,
security in a shared network environment.

Feature:    Quality of Service (QoS) improvements

The Release 5 IMS uses a policy control function (PCF) which is shown as being a
logical entity of the P-CSCF. This does not enable a generic service policy to be
       • Click to edit Master text styles
applied to both IMS and non-IMS services. This WI aims at defining a
standardized interface (the Go interface) between the PCF and application proxies
       • Second level
(e.g. P-CSCF in the IMS). Initially, a study will be performed to assess how policy
control used for IMS can interact with the appropriate IMS and non-IMS
       • Third level

      • Fourth level
Specifically, the study addresses the feasibility of the interface between the PCF
and application proxies (e.g. P-CSCF in the IMS):

Feature:    Support for subscriber certificates

Digital signatures are the best way to secure mobile commerce, service
authorization and accounting. The simplest way to introduce them in mobile
networks is to make use of the existing authorization and charging infrastructure:
they can indeed be used to provide local architecture for digital signatures.
       • Click to edit Master text styles
Subscriber certificates provide a migration path towards global Public Key
       • Second level
Infrastructure (PKI): operators do not have to wait for a world-wide PKI to benefit
from public key technology as local architecture for digital signatures can be
       • incrementally. On
deployed Third level the other hand, the existence of subscribers and
       • Fourth level
service providers that use digital signatures makes it easier to build global
PKI. The concept relies on authenticated signalling between mobile terminal and
       • Fifth level
serving network and thus has to be standardized. The terminal and the serving
network can interact only over standardized interface.

The objective is to make it possible to issue subscriber certificates in 3GPP
systems in order to authorize and account for service usage both in home and in
visited networks. This requires specification of:
•Signalling procedures to issue temporary or long-term certificates to
subscribers.
•Standard format of certificates and digital signatures, e.g re-using wireless PKI.

Feature:    Support for subscriber certificates

Digital signatures are the best way to secure mobile commerce, service
authorization and accounting. But digital signature by itself is not enough: global
support for authorization and charging is required. The simplest way to introduce

Thus, the global and secure authorization and charging infrastructure of mobile

architecture for digital signatures can be deployed incrementally; an operator can
choose to deploy independently of the others. On the other hand, the existence of
subscribers and service providers that use digital signatures makes it easier to
build global PKI. The concept relies on authenticicated signalling between mobile
terminal and serving network and thus has to be standardized. The terminal and
the serving network can interact only over standardized interface.

How to track OMA progress at 3GPP?
3GPP has identified the areas of interaction between OMA and 3GPP work. The
next step is to find a consistent way to track the progress of the OMA work at
3GPP.
      • Click to edit Master text styles
Currently, there are two different ways in the Work Plan.
      • Second level
Solution 1: the DRM way: one 3GPP working group (SA1 in the example) is
      • Third level
responsible of keeping track of the actual progress of OMA. The corresponding
MCC Secretary relays progress back to the Work Plan manager.
      • Fourth level
      • Fifth level




                                                  John M Meredith & Alain Sultan – 2003-09-15   65
How to track OMA progress at 3GPP?
(cont)
Solution 2: the LCS way: there are tasks directly allocated to OMA in the 3GPP
Work Plan. The Work Plan manager needs to find a contact person to report on
the actual progress.
      •   Click to edit Master text styles
      •   Second level
      •   Third level
      •   Fourth level
      •   Fifth level

Is there a preferred approach? Solution 2 is more accurate (as visible in the
example…) because more direct, but a contact person needs to be identified at
OMA for reporting back to the 3GPP Work Plan manager.

Unless Fifth level sufficiently important to warrant new a new work
item in their own right, they are grouped under an umbrella item “small
technical enhancements and improvements” (TEI). Each Release has such a
TEI catch-all work item, but due to its ad hoc nature, it is not shown on the
work plan.
Of course, OMA may well propose services which impinge on the features of
previous Releases, necessitating enhancements in a future Release.
