1 Scope
The present document provides the protocol details for multimedia telephony communication service and associated
supplementary services in the IP Multimedia (IM) Core Network (CN) subsystem based on the requirements from
3GPP TS 22.173 [2].
Multimedia telephony and supplementary services allow users to establish communications between them and enrich
that by enabling supplementary services.
