ABSTRACT:
A mobile packet communication system and a method of mobile packet communication, which are capable of transmitting packet data only to a specific base station area in which a mobile station for the packet communication exists without transmitting the packet data to all base stations in the same location area, are provided. Although a mobile switching center transmits a call setup information to all base stations at the beginning of the sequence, it can recognize the base station area of the mobile station by the BS area identifier which is attached by the base station to the response information. The BS area identifier is stored in the mobile switching center, and the packet data from the next sequence is transmitted only to the base station indicated in the BS area identifier. When the mobile station has moved to the other base station area during the packet communication, a BS area identifier update request signal is sent to the mobile switching center for updating the BS area identifier.
