ITU-T Y.2237 (01/2010)

Functional model and service scenarios for QoS-enabled mobile VoIP service

Recommendation ITU-T Y.2237 introduces a functional model and service scenarios for QoS-enabled mobile VoIP service in WiFi, 3G, and mobile WiMAX networks. In this Recommendation, mobile VoIP service is assumed to be provided by application of Layer 2 authentication and make-before-break based service continuity in the transport stratum.The functional model used for the description of service scenarios provided in this Recommendation is based on components and entities defined in Recommendation ITU-T Y.2012 covering user terminal, networks and media handling related aspects.
