1 Scope
The present document defines call control protocols and procedures for use in the IMS-based PSTN/ISDN Emulation
subsystem based on the Media Gateway Control Protocol (MEGACO), the Session Initiation Protocol (SIP), and the
associated Session Description Protocol (SDP).
NOTE: The present document relies on the architectural framework defined in TS 182 012 [3] for IMS-based
PES Emulation and may need to be updated once the open issues identified in the present document are
resolved.
The present document is applicable to:
• the interface between the User Equipment (UE) and the Call Session Control Function (CSCF);
• the interface between the Access Gateway Control Function (AGCF) and the Media Gateway Function
(MGF);
• the interface between the Access Gateway Control Function (AGCF) and the Call Session Control Function
(CSCF);
• the interface between the CSCF and any other CSCF;
• the interface between the CSCF and an Application Server (AS);
• the interface between the CSCF and the Media Gateway Control Function (MGCF);
• the interface between the S-CSCF and the Multimedia Resource Function Controller (MRFC);
• the interface between the CSCF and the Breakout Gateway Control Function (BGCF);
• the interface between the BGCF and the MGCF;
• the interface between the BGCF and any other BGCF;
• the interface between the CSCF and an external Multimedia IP network;
• the interface between the CSCF and the IBCF;
• the interface between the CSCF and the IBCF.
2 References
References are either specific (identified by date of publication and/or edition number or version number) or
non-specific.
• For a specific reference, subsequent revisions do not apply.
• Non-specific reference may be made only to a complete document or a part thereof and only in the following
cases:
- if it is accepted that it will be possible to use all future changes of the referenced document for the
purposes of the referring document;
- for informative references.
