Abstract

A method for restoring connectivity between a node in an IP Multimedia Subsystem IMS network and a User Equipment UE. The UE is associated with a Proxy Call Session Control Function node P CSCF of said IMS network and with at least one control node of a packet access network through which the UE connects to the IMS network. The method allows for restoring the connectivity of the UE to an IMS network node after said IMS node has failed to establish a communication to said UE via said P CSCF node.
