Performance Technique of Location Registration in System Architecture Evolution

Next generation mobile network is composed of several networks that interconnected into one common core network called as a heterogeneous network. In this heterogeneous network, the different operators will have different access networks. Therefore, there is a need to have a technique to interconnect between these different access networks. The objective of this research was to develop a new location registration technique for System Architecture Evolution (SAE) in order to support interworking between different access networks. Under the developed technique, the authentication between different networks which may not have service level agreement between them is carried out. A signaling message is developed to evaluate the performance of the registration technique. A generalized equation is formulated to investigate the location registration performance. In the simulation results, it was found that the developed technique reduces the latency and signaling cost for location registration. Therefore, this technique had improved the network performance for SAE.
