摘要:
Disclosed is a system and a method for controlling a handover of a mobile subscriber station in a broadband wireless access communication system. When serving base station determines to perform a handover of the mobile subscriber station, neighbor base stations to which the mobile subscriber station can be handed over, from among neighbor base stations of the mobile subscriber station, are determined based on a service quality level of service being currently provided to the mobile subscriber station. A handover request signal containing information related to the determined neighbor base station to which the mobile subscriber station can be handed over is transmitted to the mobile subscriber station. The serving base station receives from the mobile subscriber station in response to the request of the handover information about one neighbor base station to which the mobile subscriber station will be handed over, and informs the neighbor base station that the mobile subscriber station will be handed over to the neighbor base station.

The invention relates to a method of a first base station, BS, cooperating with at least one second BS in a mobile communication system, the method comprising: transmitting (219), to a second BS, a request message which requests to allocate resources for a mobile station, MS; receiving (223), from the second BS, a response message in response to the request message; transmitting (227), to the MS, a first message including resource configuration information of the second BS; and transmitting (323), to the second BS, a second message including a serial number, SN, of at least one data unit processed by the first BS. The invention further relates to a method and apparatus for a second BS and to a method and apparatus for a mobile station.
摘要:
Provided is a system and method for notifying completion of a network re-entry procedure in a communication system. In the system, a mobile station (MS) completes the network re-entry procedure with a base station (BS), and then notifies the completion of the network re-entry procedure to the BS.
摘要:
A system and method for state synchronization between a base station and a mobile station in a mobile communication system. A count value indicative of a state change of the base station is received. The received current count value is compared with a previous count value previously received and stored. If the current count value is different from the previous count value, the mobile station performs a network entry procedure with the base station.

Provided is an apparatus and method for negotiating sleep cycle setting between a base station and a mobile station in a wireless communication system. A method for operating a transmitter to negotiate sleep cycle setting of a mobile station in a wireless communication system includes transmitting a DSx request message including sleep cycle setting information to a receiver, and receiving a DSx response message, which includes at least one of acceptance/refusal information about DSx and acceptance/refusal information about sleep cycle setting change, from the receiver. Herein, the DSx is one of DSA (Dynamic Service Addition), DSC (Dynamic Service Change) and DSD (Dynamic Service Deletion).
摘要:
A system and method for periodic ranging in sleep mode in a communication system are provided, in which an MS is allocated an uplink burst from a BS and transmits a first message in the allocated uplink burst to the BS, the first message indicating that the MS is alive during sleep mode.
