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.

A method for requesting bandwidth allocation by a mobile station in a communication system is provided. The mobile station detects at least one Connection IDentifier (CID), bandwidth allocation for which is to be requested, generates a bandwidth request header when the number of the at least one detected CID equals one, and transmits the bandwidth request header to a base station, wherein the bandwidth request header includes a region for indicating a first CID representing basic information for identification of the mobile station, a region for indicating a ranking of the detected CID, and a region for indicating information about bandwidth requested for the detected CID.
摘要:
A method for allocating resources by a Base Station (BS) in a wireless communication system is provided. The method includes determining use/nonuse of each of a plurality of Resource Blocks (RBs), which are allocated using a persistent allocation scheme, and transmitting resource allocation information indicating use/nonuse of each of the plurality of RBs to a plurality of Mobile Stations (MSs) according to a result of the determination.
摘要:
A method of operating a Base Station (BS) in a broadband wireless communication system to resume an extended real-time Polling Service (ertPS) is provided. The method of operating the BS includes detecting a codeword received through a Channel Quality Indicator (CQI) channel, and upon receiving a CQI CHannel (CQICH) codeword for requesting resumption of an extended real-time Polling Service (ertPS) connection from a Mobile Station (MS), allocating to the MS an uplink resource corresponding to the largest maximum sustainable traffic rate of at least one ertPS connection established to the MS.
摘要:
A method is provided for allocating resources by a Base Station (BS) in a wireless communication system. The method includes persistently allocating one or more resource slots among a plurality of resource slots, the persistently allocated one or more resource slots being allocated to corresponding one or more Mobile Stations (MSs), de-allocating at least one persistently allocated resource slot of the one or more persistently allocated resource slots, determining whether a hole is created due to the de-allocation among the one or more persistently allocated resource slots not de-allocated, and shifting a location of at least one of the one or more non-de-allocated persistently allocated resource slots when it is determined that the hole is created due to the de-allocation.
摘要:
A system and method for performing a handover in a wireless communication system are provided. In the system and method an MS receives a mobile neighbor advertisement message including PDR information about a serving BS and neighbor BSs from the serving BS, selects candidate BSs based on a location of the MS and the PDR information, determines communication states of the candidate BSs, determines a target BS for the handover according to the determined communication states, and performs the handover to the target BS.
摘要:
A method for transmitting Connection Identifier (CID) information by a Base Station (BS) in a communication system is provided. The method includes transmitting a first message including information indicating a Transparent Connection Identifier (TCID) range expressed by a start value and an end value of TCIDs available in the BS, and information indicating a first transparent zone in which the BS is located, assigning one of TCIDs in the TCID range to a Mobile Station(MS) when a second message including a connection setup request from the MS is received and transmitting a third message including the assigned TCID to the MS, wherein the first transparent zone is one of a plurality of transparent zones supportable by the communication system, at least one BS is located in each transparent zone, and TCIDs in the TCID range are shared by the at least one BS included in the first transparent zone.
摘要:
An apparatus and method for providing an urgent call service in a communication system are provided. A base station receives from a mobile station a message ranging request with a Medium Access Control (MAC) address in which a priority is set. If the priority set in the MAC address is a highest priority, the base station processes the message ranging request with the highest priority and provides the urgent call service to the mobile station. Upon detecting a request for the urgent call service, the mobile station sends a message ranging request to a base station using a Medium Access Control (MAC) address in which a highest priority is set, and receives the urgent call service in response to the message ranging request.
摘要:
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.
摘要:
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.
