METHOD AND APPARATUS FOR DISTANCE-BASED LOCATION MANAGEMENT USING MOBILE STATION STATE INFORMATION IN PACKET-BASED MOBILE COMMUNICATION SYSTEM

摘要

The present invention relates to a distance-based location management method and apparatus using mobile terminal state information in a packet-based mobile communication system.;In the present invention, the location management for each mobile terminal is performed by applying a distance threshold having different values according to the state of the mobile terminal registered with the initial location. That is, when the state of the mobile terminal is in a READY state in which packet data is being transmitted or is likely to be transmitted, a distance threshold having a small value is applied to the cell where the mobile terminal is most recently registered to the cell in which it is currently located. If the moving distance of the distance exceeds the distance threshold, the location update is made. If the status of the mobile terminal is STANDBY state in which packet data is not transmitted or is less likely to be transmitted, a distance threshold having a large value is applied, and the location is updated only when the mobile distance for each mobile terminal exceeds the distance threshold. Let this be done.;Through this, paging costs can be reduced through accurate packet data transfer due to frequent location updates for mobile terminals in a ready state, and overall costs can be reduced due to location update costs for mobile terminals in standby state.
