A method of entering sleep mode in a mobile subscriber station in performing handover from a first base station (BS) to a second BS is disclosed. More specifically, the method includes entering sleep mode in the first base station and transmitting from the first base station sleep mode information in the first base station during handover, while receiving from a second base station sleep mode entry information in the second base station. The method further includes entering sleep mode based on the information the sleep mode entry information received from the second base station.

A method of controlling idle mode comprises requesting to enter idle mode by a mobile subscriber station by transmitting an idle mode request to a serving base station having a serving paging group identifier with which the serving base station is associated. The method also comprises entering the idle mode by receiving an idle mode grant command from the serving base station. The method also comprises initiating a ranging request between the mobile subscriber station and the target base station associated with the target paging group, wherein the ranging request comprises the serving base station identifier and the serving paging group identifier. The method also comprises connecting with the target base station, wherein the serving base station is informed, by using the serving base station identifier, that the mobile subscriber station is not in the idle mode with the serving base station.

A method of checking status of a mobile station in sleep mode is provided. The method includes receiving a SLP-REQ message from the mobile station; transmitting a SLP-RSP message in response to the SLP-REQ message, the SLP-RSP message including a first periodic ranging time frame offset indicating when the mobile station transmits a ranging request message; receiving the ranging request message which the mobile station transmits during a time period indicated by the first periodic ranging frame offset; and transmitting a ranging response message in response to the ranging request message, the ranging response message including information required for performing a ranging process, wherein the ranging response message further includes a second periodic ranging time frame offset if the mobile station transmits the ranging request message additionally.
