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 19):
A communication system for facilitating Proxy Call Session Control Function (P-CSCF) restoration when a P-CSCF failure on another P-CSCF has occurred, the system comprising:\n a P-CSCF; a Serving Call Session Control Function (S-CSCF); a node for controlling policy; a network node; and a user equipment (UE), wherein the P-CSCF includes:\n a receiver configured to receive, from the S-CSCF, a Session Initiation Protocol (SIP) message when the P-CSCF has been selected as an alternative P-CSCF to the other P-CSCF; and \n a transmitter configured to transmit, to the node for controlling policy, based on the SIP message, a message including a P-CSCF restoration indication; \n the node for controlling policy includes:\n a transmitter configured to transmit, to the network node, the P-CSCF restoration indication; \n the network node includes:\n a processor configured to process to initiate, at the UE, responsive to receipt of the P-CSCF restoration indication, a procedure in which a current Internet Protocol (IP) Multimedia Subsystem (IMS) connection is released; and \n the UE includes:\n a processor configured to process to release, as part of the network node initiated procedure the current IMS connection.
