System and method of making location updating management on a mobile station, mobile station and mobile network
First Claim
1. A system comprising:
- a plurality of mobile stations; and
a mobile network,wherein each mobile station comprises;
a transceiver for transmitting or receiving location management information to/from the mobile network;
a mobility model storage unit for storing one or more mobility models corresponding to activities of a user of the mobile station;
a mobility model selector, which is connected to the transceiver and the mobility model storage unit, for selecting one mobility model from the stored mobility models based on a predefined selection priority and a current location of the mobile station;
a mobility model computation unit, which is connected to the mobility model selector and the mobility model storage unit, for managing location information updating on the mobile station based on the mobility model selected by the mobility model selector; and
a location information storage unit, which is connected to the mobility model computation unit, for storing location information of the mobile station,wherein the mobile network comprises;
a transceiver for transmitting or receiving location management information to/from the mobile stations;
a mobility model storage unit for storing one or more mobility models corresponding to the one or more mobility models of the mobile stations;
a mobility model selector for selecting a corresponding mobility model from the mobility model storage unit in the mobile network based on a mobility model identification information identifying a mobility model currently being used by a mobile station received by the transceiver in the mobile network;
a mobility model computation unit for determining the current location of the mobile station based on the corresponding mobility model obtained from the mobility model selector in the mobile network.

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.
