The primary object of the present assignment to provide a mobility management method and a mobility management system for wireless data networks to precisely determine the timing that a mobility management state switches from the ready state to the standby state, and effectively resolve the synchronization problem between the mobile phone and SGSN…
Each node is required to know the topology of the network within its routing zone only. Thus, nodes are updated about topological changes only witin their routing zones. Thus, in spite of the fact that a network can be quite large, the updates are only locally propagated. Since for radius greater than one, the routing zones heavily overlap, the routing tends to be extremely robust. The routes within the network are specified as a sequence of nodes, separated by approximately the zone radius.
Mobility Management is one of the major functions of a GSM or a UMTS network that allows mobile phones to work. The aim of mobility management is to track where the subscribers are, so that calls, SMS and other mobile phone services can be delivered to them.Overview of Mobility Management The location update procedure allows a mobile device to inform the cellular network, whenever it moves from one location area to the next. Mobiles are responsible for detecting location area codes.
