Protocol impact from providing IMS services via fixed broadband; Stage-3
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.
Editor's note: The "other protocols" that are mentioned here need to be listed in detail, in order to replace the phrase "other protocols".
Editor's note: This TR will not be published.
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.
Editor's note: Agreed material is held in this TR for an interim period of time, and the material is transferred into release 7 versions of the corresponding specifications at a later time. This has the advantage that:
It creates a location where the material may stabilise outside a document under CR control, thus fulfilling the function of the original annexes in the IM CN subsystem documents.
It provides a single specification for all changes to the IM CN subsystem coming from the WID “Protocol impact from providing IMS services via fixed broadband”.
