SA1 addressed the transfer in 3GPP of TISPAN Stage 1 Multimedia Telephony (MMTEL) Release 2, needed to implement the MMTEL for the Common IMS concept.

As a result, TISPAN Stage 1 TS 181 002 v.2.2.3 (Release 2) was transferred and integrated into 3GPP TS 22.173. Requirements relevant to MMTEL contained in TISPAN TS 181 005 v2.1.0 were also integrated in TS 22.173.

The SA5 IMS charging specifications were not fully covering MMTel supplementary services. Thus, supplementary service charging was included in IMS session charging.

SA5 introduced MMTel charging in 3GPP IMS as a new TS 32.275. Existing TS 32.298 and TS 32.299 added MMTel supplementary services AVPs from Telephone Application Server and corresponding charging fields in the Charging Data Records (CDRs).
