A location update method in a wireless communication system is disclosed. The method for performing a location update in a mobile station (MS) of the wireless communication system including a femtocell includes receiving a deregistration command (DREG-CMD) message that includes not only a paging group identifier (ID) of a first femtocell base station (BS) in which the MS stays but also a paging group ID of a macro BS including the first femtocell BS, initiating a location update delay timer while the MS moves from the first femtocell area to a second femtocell area having a paging group ID different from that of the first femtocell, and performing location update according to an operation of the location update delay timer.

A method for detecting coverage loss during a sleep mode of a mobile station and an apparatus for performing the same are disclosed. The method for detecting coverage loss of a mobile station, which is operated in a sleep mode, in a broadband wireless access system comprises the steps of awaking regardless of a sleep window of a sleep cycle at a first time when a super frame header (SFH) is transmitted from a serving base station; detecting the super frame header; and operating for the sleep window or listening window in accordance with the sleep cycle if the detected result is successful, and awaking until the super frame header is successfully detected if the detected result is failed.
摘要:
The present invention relates to a broadband wireless access system including a femto cell, and more particularly, to a method of low duty operation in a femto base station. According to one embodiment of the present invention, in a broadband wireless access system, a method of a low duty mode operation of a femto base station saving power includes the steps of determining a low duty mode pattern to be performed by the femto base station according to a preset reference and performing the low duty mode operation according to the determined pattern. In this case, the preset reference can include at least one selected from the group consisting of a battery level, an available resource status and a subscriber type of the femto base station.

A method for paging in a wireless access system is disclosed. A method for efficiently paging a mobile station of an idle mode comprises allocating an identifier of a large paging group and an identifier of a specific one of small paging groups included in the large paging group to a broadcast channel region and transmitting a header including the broadcast channel region to the terminal. Accordingly, the present invention enables efficient paging.
摘要:
A method of allocating a paging carrier in a multi-carrier environment is disclosed. The method of allocating the paging carrier includes receiving a first message including first allocation information of the paging carrier, transmitting a second message for requesting entry into an idle mode to a base station; and receiving a third message including second allocation information of a changed paging carrier from the base station. At this time, the paging carrier includes a paging channel out of multiple carriers including one or more carriers.
摘要:
A location update method and a mobile station using the same are disclosed. The location method includes receiving a message including femto Base Station (BS) list information from a macro base station, receiving a preamble including an IDentifier (ID) of a first femto BS from the first femto BS during a predetermined interval, and updating a location to the first femto BS, if the ID of the femto BS is identical to one of IDs included in the femto BS list information. The femto BS list information may include IDs of one or more femto BSs included in the macro BS.
摘要:
A method and apparatus for performing a location update based on mobility information indicating a velocity of a Mobile Station (MS), and a method and apparatus for using a timer for a location update in a wireless access system are disclosed. The MS transmits a deregistration request message requesting initiation of idle mode to a first Base Station (BS), receives a deregistration command message including paging group information from the first BS, the paging group information including a primary paging group Identifier (ID) and primary paging offset of a primary paging group allocated to the MS, and a secondary paging group ID and secondary paging offset of a secondary paging group allocated to the MS, and activates a paging group location update timer after moving from the primary paging group to the secondary paging group. The deregistration request message includes first mobility information indicating a velocity of the MS and the paging group information is set based on the first mobility information.
