1  ScopeWord‑p. 7

The present document is a temporary container for the functional models, flows and protocol details for the IM CN subsystem behaviour when providing IMS services via fixed broadband access. This service is based on the Session Initiation Protocol (SIP), the Session Description Protocol (SDP), other protocols, the Gq interface and the Cx interface. The contents of this report will be moved into appropriate 3GPP Technical Specifications.
The document focuses on scenarios where a non-3GPP terminal is connected via a fixed broadband access network to the IMS.
Where possible the present document specifies the requirements for the above mentioned protocols by reference to specifications produced by the IETF within the scope of SIP, SDP and other protocols, either directly, or as modified by 3GPP specifications. Where this is not possible, extensions are defined within the present document..
The present document includes information applicable to network operators, service providers and manufacturers.
