The next generation wireless communication system aims at supporting multimedia services with different Quality of Services (QoS) and bandwidth requirements. Therefore effective management of limited resources is important to enhance network performance. Access Service Network GateWay (ASN GW) relocation is the process of changing the traffic's Anchor Point (AP) from one GW to another which is independent of Mobile Station's (MS's) Link Layer (LL) handover.
