Abstract:
1. A method for controlling a mobile subscriber station in a communication system, the method comprising the steps of: mode-transitioning into an idle mode when the mobile subscriber station is in an inactive state; detecting movement of the mobile subscriber station in the idle mode into another paging zone to which a target base station belongs, which paging zone is different from a paging zone to which a serving base station of the mobile subscriber station belongs; mode-transitioning into an awake mode and performing location update with the target base station based on the detected movement of the mobile subscriber station, wherein the location update is carried out by transmitting a location update request to the target base station and receiving a location update response from the target base station; and mode-transitioning from the idle mode into the awake mode when the mobile subscriber station detects a paging targeting the mobile subscriber station itself, by receiving paging information broadcasted from the serving base station in accordance with a paging cycle, and recognizing existence of the paging when the paging information contains a mobile subscriber station identifier of the mobile subscriber station.
