PURPOSE: A call processing method of a mobile communication system is provided to reduce an unnecessary power consumption and a call standby time of a mobile terminal by determining whether a corresponding call channel has been searched by using an indicator existing in a high speed call channel slot. CONSTITUTION: A searcher of a mobile station computes the next slot time that the next mobile terminal system is to wake up by using a slot period length(S10). If the slot time that the mobile position is positioned(S11), the searcher of the mobile station becomes a sleep state and recomputes the next slot time from the slot time and the slot period length that the current mobile station of a call channel is positioned. The searcher of the mobile station determines whether a corresponding base station of the mobile station supports a high speed call channel(S12). If the corresponding base station does not support the high speed call channel, the searcher operates a system in the corresponding slot of the call channel to search whether there is a message transmitted to its mobile station(S13). If the corresponding base station of the mobile station supports the high speed call channel, the searcher computes a position of the high speed call channel slot(S14). The searcher computes positions of two call indicators(PI) supported through the high speed call channel by a Hash function(S15). The system of the mobile station is operated at the slot position of the determined call indicator to check a call indicator(PI) bit(S16). The bit of the call indicator(PI) is searched during the operation time of the estimated mobile station system(S17). If the first call indicator(PI) is ON, the second call indicator(PI) bit is checked(S18). If the second call indicator(PI) is OFF(S19), it becomes a sleep state till the next slot(S20). |
