Abstract: A method, system and computer readable media for reducing Packet Gateway (PGW) initiated signaling with a Serving Gateway (SGW) is presented. In one example embodiment a method for reducing Packet Gateway (PGW) initiated signaling with a Serving Gateway (SGW), includes determining by the PGW that a Packet Data Network (PDN) is undergoing S1-handover
with the SGW-relocation; buffering, by the PGW, bearer procedure messages and starting a guard timer; and re-attempting the buffered messages until a condition has been met.
