RFC 6910 (was draft-ietf-bliss-call-completion)

As part of the agreement of moving common IMS work from ETSI TISPAN to 3GPP, there is a need to ensure that the work on simulation services that are still not frozen within TISPAN is continued within 3GPP. Within TISPNA the WI 3035 (TS183042) on the description for CCBS and CCNR is still within the draft status.

This work creates Stage 3 for CCBS/CCNR-like service in 3GPP IMS. New capabilities are in line with RFC3427. Interoperability between networks was taken into consideration. Interworking was specified.

During the joint workshop on common IMS in January 2008, 3GPP and 3GPP2 agreed on principles to incorporate parts of 3GPP2 MMD/IMS related specifications into 3GPP within the Rel-8 timeframe. This work incorporates the Flexible Alerting supplementary service specified in 3GPP2 X.P0055: MMD Supplementary Services.

SA1 covered Stage 1 in TS 22.173.

CT1 covered Stage 3 in TS 24.173 and new TS 24.239.
