Method and apparatus for distance-based location management using mobile station state information in packet-based mobile communication system

The present invention is a packet-based mobile distance-based location management with a mobile terminal-specific state information in a communication system and method relating to the device. In the present invention, by applying a threshold distance has a different value depending on the state of the initial position registered mobile terminal performs the management by the mobile terminal. That is, if the mobile terminal status packet data, the status transmission is or are likely to be transferred ready (READY), by applying the distance threshold having a value, to the cell that the mobile station is currently located from a position registered with a cell in the most recent If the travel distance exceeds the distance threshold, and the location update to occur. And, if the mobile terminal status packet data is low or not transmission probability of transmission standby (STANDBY) state, by applying a distance threshold having a greater value, the update only in the position if the distance traveled by the mobile terminal exceeds the distance threshold this will be done so. Through this, reducing the paging costs with accurate packet data transmission due to the frequent location update for a ready state of the mobile terminal, and can achieve an overall cost reduction due to the location update cost for a mobile terminal standby.
