A method for providing an emergency service by an idle mode Mobile Station (MS) in a communication system includes receiving, from a Base Station (BS), a broadcast message including information on a time duration in which an emergency service message will be transmitted after waking up at a start timing point of a paging listening interval, transitioning into an idle state when a start timing point of the time duration in which the emergency service message will be transmitted is later than a timing point at which the paging listening interval is terminated, and waking up at the start timing point of the time duration in which the emergency service message will be transmitted after transitioning into the idle state.

Abstract: 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.

The operation of the base station includes persistently allocating resources to at least one mobile station and transmitting, in a current frame, a control information message including a change counter flag indicating whether persistent resource allocation information, transmitted in a previous frame, is changed. An operation of the mobile station includes receiving a control information message, including a change counter flag indicating whether persistent resource allocation information included in a control information message transmitted in a previous frame is changed, from a base station in a current frame and checking a value of the change counter flag.

Abstract: An apparatus and method for persistent allocation in a wireless communication system are provided. An operation method of a Base Station (BS) includes determining if decoding information for one or more persistent allocations assigned to one or more corresponding Mobile Stations (MSs) is updated, if the decoding information is updated, generating a signaling message to signal the update of the decoding information, and transmitting the signaling message through a DL MAP. The signaling message includes an R_CID and ACID associated with at least one persistent allocation to which the updated decoding information is to be applied.

Abstract: A method and apparatus for transmitting/receiving a connection identification (CID) in a communication system is provided. Upon detecting a need for its handover, a mobile station (MS) transmits a handover request message to a first base station (BS) in communication with the MS. Upon receiving the handover request message, the first BS transmits at least one CID for connection setup to a second BS to which the MS will perform handover, to the MS along with a handover response message in response to the handover request message. The MS receives the CID through the handover response message.

In the method, at least one Base Station (BS) ID index assigned to a serving base station by at least one neighbor base station is confirmed. A target base station for a handover is confirmed. A temporary MS ID is formed using a BS ID index assigned to the serving base station by the target base station, and an MS ID index assigned to the mobile station by the serving base station. A network re-entry procedure with the target base station is performed using the temporary MS ID. Communication with the serving base station is performed until the network re-entry procedure with the target base station is completed.
