AN EFFICIENT PAGING METHOD FOR REDUCING POWER CONSUMPTION OF MOBILE COMMUNICATION TERMINAL IN PACKET DATA SERVICE SYSTEM, AND PACKET DATA SERVICE SYSTEM FOR THE SAME

摘要

An efficient paging method for reducing power consumption and a packet data service system therefor are provided to enable a terminal to check whether a paging message exists through a frame control header before decoding a map message and enable the terminal to reduce a frequency of decoding a map message and a paging message, thereby reducing power consumption. A base station sets a paging indicator value which indicates whether a paging message exists by using a reserved bit of an FCH(Frame Control Header) to transmit a frame(S120). A terminal performs a listening operation within a preset time with a system. The FCH is decoded to obtain the paging indicator from a corresponding frame(S130). When the paging indicator value is a value indicating that a paging message exists(S140), the map message is decoded(S150). When the paging indicator value is a value indicating that a paging message does not exist, the terminal performs S130 step as long as a listening interval lasts.
