ABSTRACT:
For realizing a mobile communication network highly compatible with the Internet and improving channel efficiency and battery conservation in a mobile communication system including a plurality of base stations connected to IP network, a plurality of mobile stations locating in a cell formed by base station, and a server, connected to the IP network, for managing location information of the mobile stations, wherein a set of cells constitutes a paging area, whereas the server manages information of a standby mobile station as location information of mobile stations about paging area in which mobile station locates; the server determines whether a mobile station is in standby state or not when a base station transfers to the server a packet addressed to the mobile station and, if the mobile station is in the standby state, copies the packet by the number of the base stations corresponding to the paging area related to the mobile station and multicasts thus copied packets.
