Geneva, 13-16 July 2009
Fostering worldwide interoperability
Common IMS (1)
Under the Common IMS Initiative,
3GPP and 3GPP2 successfully rolled
all the 3GPP2 enhancements to IMS
back into the 3GPP specifications.
Going forward, all further IMS work
will be done in 3GPP, with member
companies representing the needs of
the CDMA community.
With the success of Common IMS,
there is now a single IMS system for
the industry

The following specifications have been capped in TIA
accordingly:
TIA-873-B, All-IP Core Network - Multimedia Domain
TIA-1032-A, Presence Service
TIA-1069, Conferencing using the IP Multimedia Core Network
TIA-1091-B, IMS Security Framework
TIA-1111, VoIP Emergency Services
TIA-1112, SIP-ISUP Interworking

Interoperability and Interworking
Two projects are in progress in
3GPP2 to support IP level
convergence
e(evolved)HRPD/E-UTRAN Interoperability, and
HRPD/WiMAX Interoperability
The first releases of both were
published in 1Q09, addendums and
revisions are in progress and
scheduled for completion EOY09.

Strategic Direction
TSB-183, Common IMS Impacts to
3GPP2 Specifications, has been
developed to provide both
a mapping of the 3GPP2/TIA documents to the
3GPP Common IMS counterparts, and
information regarding differences in IMS
network elements and interfaces between
3GPP2/TIA and 3GPP specifications for interworking purposes
Close collaboration between 3GPP2
and both 3GPP and WiMAX Forum is
in place to support Interoperability
and Inter-working

Challenges
Ensure ongoing compatibility between
TIA standards and Common IMS
specifications
Ensure TIA requirements are met in
the Common IMS specifications
TSB-183 will be updated
appropriately as new CDMA-based
material is incorporated into Common
IMS
Maintain ongoing interworking
between different access technologies

Next Steps/Actions
Prepare additional documents in
3GPP2 for potential inclusion in
Common IMS post Rel. 8
TIA has published TIA-1127, MMD Enhanced
Policy, and this may be proposed for inclusion
in 3GPP Rel. 10, based on operator interest
As future IMS-based functionality is proposed
in TIA/3GPP2, applicability for Common IMS
will be a key consideration
Continue close collaborative work
with 3GPP and WiMAX Forum
