Abstract
A method for controlling operation modes of a medium access control layer by a mobile subscriber station in a broadband wireless access communication system including the mobile subscriber station and a serving base station providing service to the mobile subscriber station is provided. The method includes the steps of: mode-transiting into an idle mode when there is no data transmission between the serving base station and the mobile subscriber station during a predetermined first time interval in an awake mode; detecting movement of the mobile subscriber station in the idle mode into another paging zone covering a target base station, which is different from a paging zone covering the serving base station; and mode-transiting into the awake mode and performing location update together with the target base station when the movement of the mobile subscriber station is detected.

37. 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; and
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. - View Dependent Claims (38, 39, 40, 41, 42)

43. 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 there is no data transmission between a serving base station and the mobile subscriber station during a predetermined first time interval in an awake mode; and
mode-transitioning into the awake mode and performing location update cyclically at a predetermined idle interval in the idle mode, 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. - View Dependent Claims (44, 45, 46, 47, 48, 49)

50. A system for controlling a mobile subscriber station in a communication system, the system comprising:
-
the mobile subscriber station adapted to mode-transition into an idle mode when the mobile subscriber station is in an inactive state, to detect 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, and to, based on the detected movement of the mobile subscriber station, mode-transition into the awake mode and perform location update with the target base station; and
the target base station performs the location update with the mobile subscriber station, wherein the mobile subscriber station performs the location update by transmitting a location update request to the target base station and receiving a location update response from the target base station. - View Dependent Claims (51, 52, 53, 54, 55, 56)

57. A system comprising:
-
a mobile subscriber station adapted to mode-transition into an idle mode when there is no data transmission between a base station and the mobile subscriber station during a predetermined first time interval in an awake mode and to mode-transition into the awake mode and perform location update cyclically at a predetermined idle interval in the idle mode; and
the base station performs the location update with the mobile subscriber station, wherein the mobile subscriber station performs the location update by transmitting a location update request to the base station and receiving a location update response from the base station. - View Dependent Claims (58, 59, 60, 61, 62, 63)
