Abstract
Example embodiments are presented herein which relate to signaling in the presence of a Proxy-Call Session Control Function (P-CSCF) node failure or restart in a Proxy Mobile Internet Protocol (PMIP) based network. The example embodiments provide a means for a PGW or GGSN, which functions as a Local Mobility Anchor (LMA), to provide an update or indication of the P-CSCF failure or restart directly to a Serving Gateway, which functions as a Mobility Access Gateway (MAG).
