Multimedia telephony over distributed service networking
|Publication Date:||1 August 2014|
This Recommendation specifies a cost-effective, flexible, scalable and reliable system which provides multimedia telephony (MMTel) services to users connected to a distributed service networking (DSN) network. It describes the requirements and functional architecture for supporting MMTel services over DSN, defines detailed information flows related to MMTel service provisioning, node management and overload control. It also describes the support for supplementary services, mobility, interworking, charging, and network management in an MMTel system over DSN.
