Abstract
To consolidate session initiation protocol (SIP) messages a user equipment (UE) is made aware of all Internet Protocol (IP) multimedia subsystem (IMS) applications installed in its memory and on a universal integrated circuit card (UICC) and supported communication services. By obtaining this information before the initial IMS Registration, the UE can save resources by registering all local applications and communication services in single IMS registration.
