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 15):
A method of a Serving Call Session Control Function (S-CSCF) for a restoration procedure of a Proxy Call Session Control Function (P-CSCF), comprising:\n receiving a terminating Session Initiation Protocol (SIP) message; detecting a P-CSCF failure on a P-CSCF; causing a node for controlling policy to send a P-CSCF restoration indication to a network node; and receiving another SIP message for Internet Protocol (IP) Multimedia Subsystem (IMS) registration for a User Equipment (UE) from the UE after sending the P-CSCF restoration indication to the network node, wherein release of a current IMS Packet Data Network (PDN) connection in the UE, as part of the network node initiated procedure is initiated based on the P-CSCF restoration indication.
