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 16):
A method, performed in a communication system including a Proxy Call Session Control Function (P-CSCF), a Serving Call Session Control Function (S-CSCF), a node for controlling policy, a network node, and a User Equipment (UE), of facilitating P-CSCF restoration when a P-CSCF failure on another P-CSCF has occurred, the method comprising:\n receiving, by the P-CSCF, 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; sending, by the P-CSCF, to the node for controlling policy, based on the SIP message, a message including a P-CSCF restoration indication; sending, by the he node for controlling policy, to the network node, the P-CSCF restoration indication; initiating, by the network node, 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 releasing, by the UE, as part of the network node initiated procedure, the current IMS connection.
