1  Scopep. 5

The present document provides a Session Initiation Protocol (SIP) based protocol framework that serves as a means of user configuration of supplementary services in the IP Multimedia (IM) Core Network (CN) subsystem. The protocol framework relies upon the contents of the Request-URI in a SIP INVITE request to enable basic configuration of services without requiring use of the Ut interface.
The present document is applicable to User Equipment (UE) and Application Servers (AS) which are intended to support user configuration of supplementary services.
