Abstract

The invention provides a system and method for location management in a mobile network through sharing individual mobility model between a mobile station and the mobile network. The mobile station and the mobile network always exchange large amounts of data in order to make location updating management in the conventional way, which in turn results in an increase in the overall network overhead and wastes the network resource. The system and method of the invention makes location management in both the mobile station and the mobile network by sharing the mobility model reflecting the action regulation of the mobile station between the mobile station and the mobile network, such that the network overhead is greatly reduce.
