    摘要： A method of indicating downlink traffic to a mobile subscriber station that is in a sleep mode includes transmitting a sleep request message to a base station (BS); entering the sleep mode in response to a sleep response message received from the BS, wherein the sleep response message includes a first SLPID; receiving a traffic indication message including a FMT field indicating formats for the traffic indication message from the BS during a listening interval of the sleep mode, wherein the FMT field indicates one of an SLPID bitmap based format and an SLPID based format, and the traffic indication message further includes a second SLPID when the SLPID based format is used; and terminating the sleep mode to receive the downlink traffic when the second SLPID in the traffic indication message is same as the first SLPID included in the sleep response message.

    摘要： A method of providing neighbor base station information via a mobile subscriber station in a broadband wireless access system is disclosed. In providing neighbor base station information (S316) to a serving base station from a mobile subscriber station in a broadband wireless access system, the present invention includes the steps of performing a scanning and a synchronization (S312, S313) on a mobile base station based on information provided from the serving base station (S311) and transmitting the neighbor base station information acquired from the scanning and the synchronization to the serving base station (S316) regardless of a presence or non-presence of a request from the serving base station. Accordingly, the present invention can efficiently transmit the neighbor base station signal intensity and frame information acquired by the mobile subscriber station.

    摘要： A method uses inter-base station control messages to provide neighbor base station information to mobile subscriber stations in a mobile communication system. The method includes obtaining, at a serving base station, physical channel information of neighbor base stations over a backbone network via, either directly or via a server; periodically transmitting the obtained physical channel information from the serving base station to a mobile subscriber station connected to the serving base station; and measuring, based on the updated physical channel information, signal quality of the at least one neighbor base station at the mobile subscriber station. Thus, the serving base station receives from the neighbor base stations the inter-base station control messages containing the neighbor base station information, updates the information, and provides the updated information to the corresponding mobile subscriber station(s), to be used for a specific purpose such as handover or network entry.
