Assist Reordering Of Downlink Data At Serving GW Relocation

Abstract

A packet data network gateway (PDN-GW) on a wireless telecommunications network having a target radio access network (RAN) and a Serving (GW) includes a process-unit which generates an end marker packet The PDN-GW includes a network interface which sends the end marker packet onto the network to assist the target RAN in reordering of downlink data. A method for a packet data network gateway (PDN-GW) on a wireless telecommunications network having a target radio access network (RAN) and a Serving (GW) includes the steps of generating an end marker packet with a processing unit. There is the step of sending the end marker packet onto the network with a network interface to assist the target RAN in reordering of downlink data.
