摘要：In the Multiple-Operability Mobile Systems, mobile users (MUs) will be able to move across various heterogeneous networks while using their mobile terminals (MTs) to co mmunicate. It has been proven that this global roaming freedom signi.cantly increases the network-signaling traffic. Several schemes have been recently proposed to reduce such a traffic. This paper presents an efficient approach which uses a special gateway called Wireless INterwo rking Gateway (WING) to facilitate interoperability between heterogeneous subsystems of the NG wireless systems. Results reveal that such an approach signi.cantly improves the network performance, in terms of generated signaling traffic and response time during the global roaming process
