Abstract:
A method of facilitating P-CSCF restoration when a P-CSCF failure has occurred is disclosure. The method comprises a Proxy Call Session Control Function, ‘P-CSCF’ receiving a Session Initiation Protocol, ‘SIP’, message when said P-CSCF has been selected as an alternative P-CSCF to a failed P-CSCF and providing, to an associated Policy and Charging Rules Function, ‘PCRF’, a message comprising an indication that P-CSCF restoration is required.

Claim (Index 17):
A user equipment (UE) for facilitating Proxy Call Session Control Function (P-CSCF) restoration in a communication system when a P-CSCF failure has occurred, the UE comprising:\n a memory storing instructions; and at least one processor configured to process the instructions to:\n release, as part of a network node initiated procedure a current Internet Protocol (IP) Multimedia Subsystem (IMS) connection, \n wherein the releasing is initiated based on a P-CSCF restoration indication which is sent from a node for controlling policy to the network node; and \n send a Session Initiation Protocol (SIP) message for IMS registration for the UE, to a Serving Call Session Control Function (S-CSCF) after the P-CSCF restoration indication is sent.
