Rel-7 work on IMS protocol fulfilled a useful purpose in separating all minor IMS enhancements needing progress. Rel-8 WID has an identical scope (with the removal of 24.930).

IMS was defined in Rel-5 to support IP Multimedia services and provided the basis for IP Multimedia support. Rel-6 and Rel-7 further improvements were made. Rel-8 identified new capabilities and there is still significant IETF ongoing work that should be documented in relation to its impact on IMS.

This work aligned protocol between 3GPP Stage 3 IMS and IETF, reviewed IETF provided SIP capabilities, and documented whether these capabilities are supported in the IMS or not.

In addition, minor technical enhancements to IMS, not of sufficient significance to be normally covered by a work item, were covered by this work item.

SA1 identified the requirement of MGCF (Media Gateway Control Function) interworking between UUS and SIP. This MGCF interworking makes possible the CSI (CAMEL Subscription Information) capability exchange between UEs that use CSI and UEs that use IMS with IMS origination and CSI termination.

The purpose of CSI capability exchange is to enrich communication for CSI termination. So the user of CSI capable UE can expect same user experience in case remote party is IMS capable UE.

Hence, Stage 3 should properly cover the MGCF interworking to enable transportation of CSI capability information and the CSI capability exchange for IMS originated sessions leading to CSI session termination.

This work aligns the agreed Stages1 and 2 with Stage 3 along with the provision of relevant Stage 3 capabilities and functionalities to elaborate the MGCF interworking as defined in TS 22.228 and the functional involvement of the CSI capability exchange defined in TS 23.279.

TS 22.228 requires IMS support interoperability of UUS service with the PSTN/ISDN and vice versa. This was applied from TISPAN Stage 1.

Stage 2 requirement of CSI capability exchange and MGCF interworking between UUS1 and SIP is part of TS 23.279.

This work:

  • implements the MGCF interworking between UUS and corresponding SIP as defined in Stage 1 requirements (CT3 related part);

  • includes UUS into SIP header (CT3 and CT1 common part);

  • includes CSI capability exchange feature in CT1 as defined in Stage 2 (CT1 related part)

NOTE 1: This work only covers UUS1 implicit aspects of UUS interworking

NOTE 2: Extensions to SIP should be developed in accordance with 3GPP agreements with IETF, see RFC 3113.
