摘要:
A method for controlling operation modes of a medium access control layer by a mobile subscriber station in a broadband wireless access communication system including the mobile subscriber station and a serving base station providing service to the mobile subscriber station is provided. The method includes the steps of: mode-transiting into an idle mode when there is no data transmission between the serving base station and the mobile subscriber station during a predetermined first time interval in an awake mode; detecting movement of the mobile subscriber station in the idle mode into another paging zone covering a target base station, which is different from a paging zone covering the serving base station; and mode-transiting into the awake mode and performing location update together with the target base station when the movement of the mobile subscriber station is detected.

An apparatus and method for seamlessly providing voice and data services to a user through an access terminal in a mobile communication system including a heterogeneous service & mobility gateway (HSMG) for an interworking service between a circuit network and a packet network, and various access networks overlapping each other. The access terminal notifies the HSMG that a voice call is received, if the access terminal that accessed a packet network receives a voice call. The HSMG sends a direction request to a circuit network upon receiving the notification indicating that the voice call is received. The access terminal directs to the circuit network and registers a new location upon receiving the direction request. The HSMG sets up an incoming voice call to the access terminal after the registration of a new location.

A network includes a Mobile Station (MS) for sending a Service Flow (SF) modification request message to a Base Station (BS) to modify an SF. The BS sends a path modification request message to a serving SF Authorization (SFA) when there is the information on the SF. The BS also sends an SF modification response message comprising a Confirmation Code ‘Reject SF not found’ to the MS when there is no information on the SF. The serving SFA sends a resource reservation request message to an anchor SFA when there is the information on the SF, and sends a path modification response message comprising a Failure Indication (FI) ‘Requested Context Unavailable’ to the BS when there is no information on the SF. The anchor SFA sends a resource reservation response message comprising the FI ‘Requested Context Unavailable’ to the serving SFA when there is no information on the SF.

A method and apparatus for transmitting and receiving resource allocation information in a communication system are provided, in which a Base Station (BS) transmits resource allocation information including a folding bitmap and a Zone Flag (ZF). The folding bitmap provides zone configuration information about zones included in a subframe and the ZF indicates whether a last zone of the zones is allocated as a first service zone or a second service zone. The first service zone carries data for a first service, the second service zone carries data for a second service, and each of the first and second services zones includes at least one resource unit.

An apparatus and method are provided for load balancing in a broadband communication system. In an initial network entry/network reentry/handover, whether to allow a user terminal and whether to allow each service flow are checked. The channel state and load state of candidate frequency assignments and subcells are detected. The ranging status of a corresponding frequency assignment or a corresponding subcell is set according to whether to allow the user terminal. The allowable candidate frequency assignment and subcells are selected and transmitted.

An apparatus and method for managing quality of service (QoS) of a service flow in a wireless communication system are provided. A method of operating a base station (BS) in a wireless communication system includes receiving QoS policy information of mobile stations (MSs) from a network entity including a policy decision function (PDF) or from neighbor BSs, and storing the QoS policy information; detecting a mobile station attempting connection re-establishment; upon detecting the mobile station attempting connection re-establishment, evaluating a QoS policy of the mobile station; and controlling a state of a service flow generated for the mobile station according to the QoS policy.
摘要:
A method for transmitting burst allocation information by a base station in a broadband wireless communication system in which a transmitted frame includes symbols, and orthogonal subcarriers in a frequency axis constitute each of the symbols based on a predetermined time unit. The method includes the steps of generating a reduced connection identifier (CID) by reducing a basic CID of a mobile terminal connected to the base station when the basic CID exists within a preset range, and inserting an MAP, which includes an enabled field representing the reduced CID and one of use and non-use of the reduced CID, into the frame, and transmitting the frame to the mobile terminal.
