摘要： Disclosed is a handover system in a BWA communication system. In the system, a serving BS broadcasts neighbor BS information including BS identifiers of a plurality of neighbor BSs and reference signal indices indicating reference signals used by the neighbor BSs, a MS receives the neighbor BS information and requests a scanning interval to the serving BS at a timing point at which the MS wants to perform a scanning, the serving BS allocates the scanning interval to the MS in response to a request for the scanning interval, and the MS scans reference signals received from the neighbor BSs during the scanning interval in response to the neighbor BS information.

摘要： Disclosed is a system and method for performing soft handover in a broadband wireless access communication system. An anchor base station transmits first information including channel assignment information of an active non-anchor base station when it is determined that a mobile station is to perform the soft handover, and when there are signals to be transmitted to the mobile station from the non-anchor base station, the non-anchor base station transmits second information including channel assignment information of the anchor base station when it is determined that the mobile station is to perform the soft handover, and when there are signals to be transmitted to the mobile station from the anchor base station, and the mobile station receives signals from the anchor base station and the non-anchor base station corresponding to the first information and the second information when it is determined that the mobile station is to perform the soft handover.

摘要： A method and system for transmitting/receiving a neighbor base-station information message in a broadband wireless access system. A method includes receiving, by the mobile station, a neighbor BS information message; determining whether or not an operator ID field related to a first neighbor BS is included in the neighbor BS information message; and determining that the first neighbor BS has identical BS information as a serving BS, if the operator ID field is not included in the neighbor BS information message.

摘要： Disclosed is a method and system for transmitting/receiving a neighbor base-station information message in a broadband wireless access system. A base station sets and transmits a neighbor base-station information message, which includes a specific flag field for limiting neighbor base-station information and a reserved field and omits iterative neighbor base-station information depending on a value set in the specific flag field, thereby increasing a transmission efficiency. A mobile terminal receives the neighbor base-station information message from the base station, checks the received message, and then updates an operator ID according to the value set in the specific flag field.
