A method for controlling a sleep mode operation by a Mobile Station (MS) in a communication system. The MS includes transitioning to an awake state in a listening interval of the sleep mode; performing any one of a first operation, a second operation and a third operation in the awake state; and after any one operation is performed, transitioning to a sleep state upon detecting that there is no data to transmit to the BS and there is no data to be received from the BS. The first operation is a process of receiving data from the BS, the second operation is a process of transmitting data to the BS, and the third operation is a process of receiving data from the BS and receiving data from the BS.

Method for operating control sleep mode in a communication system

A method for providing service in a communication system. A base station (BS) receives a request message for requesting a service from a mobile station (MS) located in a first service zone; and transmits to the MS a response message including information on a BS located in a service zone supporting the requested service. The MS transmits a request message for requesting a service to the BS located in the first service zone, and receives a response message including information on a BS located in a service zone supporting the requested service, from the BS located in the first service zone.

Method and system for providing service in a communication system

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.

A system and method for providing an emergency service in a communication system is provided. 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.

System and method for providing an emergency service in a communication system

An apparatus and method for operating a base station and a mobile station in a communication system are provided. 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.

Apparatus and method for transmitting and receiving control information message in a communication system

A method and system are provided for transmitting broadcast service data in a wireless communication system using an Orthogonal Frequency Division Multiple Access (OFDMA) scheme in which data transmission is achieved through a downlink and an uplink within one frame. The system being connected to a broadcast server. The system and method include allocating a connection identifier (CID) to each broadcast service for identification of a broadcast service packet transmitted over the downlink, and transmitting broadcast service information for each broadcast service; and receiving a broadcast packet from the broadcast server, and transmitting a physical layer transmission information element (DL-MAP) including a broadcast service CID for the broadcast packet through the downlink0.

Method and system for transmitting and receiving broadcast service data in a wireless communication system

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.

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.
