摘要： A method and a system is disclosed for controlling a sleep mode in broadband wireless access communication system. The subscriber terminals are managed by grouping the subscriber terminals in a broadband wireless access communication system, so an efficiency for controlling the sleep mode of the broadband wireless access communication system may increase. A further advantage is provided that each point of time for transmitting a paging message of each group is established differently from each other within a unit time slot for controlling the sleep mode, such that subscriber terminals are managed according to groups. Another advantage is provided that the base station can previously find subscriber terminals awaking at each point of time for transmission the paging message of each other from among subscriber terminals having the sleep mode, so an efficiency for controlling the sleep mode of the broadband wireless access communication system may increase.

摘要： An apparatus and method for controlling a sleep mode in a wireless access communication system. The apparatus determines a predetermined number of groups for grouping at least one subscriber terminal according to type information of a paging interval equal to the sum of the sleep interval and the listening interval, and registers the subscriber terminal in one group from among the groups on the basis of the paging interval type of the subscriber terminal. Upon receipt of the group information, the apparatus controls a base station to pre-recognize a terminal woken up at a predetermined time from among a plurality of terminals entering the sleep mode, resulting in reduction of the number of unnecessary paging message transmissions and improved efficiency of the wireless access communication system.

摘要： Disclosed is an apparatus and method for recovering a communication link between a Mobile Station (MS) and a Base Station System (BSS) in a mobile communication system when the communication link is disconnected while a communication service is in progress. When detecting the disconnection, the MS stores information of the communication link. If the MS acquires synchronization with the BSS within a predetermined time period from the detection, it resumes the communication service through the communication link. Upon the disconnection, the BSS stores resource and other information of the MS. If the BSS detects that the MS has acquired synchronization with the BSS within the predetermined time period from the disconnection, the BSS resumes the communication service through the communication link. This ensures a stable communication service in a mobile communication system that has many radio dead zones where the MS cannot normally receive services.

摘要： A registration response (REG_RSP) message is generated which includes a type field, a length field, and an integrated CID (Connector Identifier) field. The integrated CID field includes an integrated CID inserted thereinto. The integrated CID is configured by using a new CID assigned to the subscriber terminal and an old CID assigned to the subscriber terminal by a current serving base station. The type and length fields include type information and length information of the integrated CID respectively inserted thereinto. The generated REG_RSP message is transmitted to a handover target subscriber terminal. A traffic indicator (TRF_IND) message is generated which includes at least one short BCID (Basic Connector Identifier) field into which a short BCID is inserted. The short BCID is configured by a preset number of bits among a total of bits representing a BCID of a positive subscriber terminal that must receive traffic indication information. The generated TRF_IND is then broadcast.

摘要： An apparatus and method for separating data units from a received concatenated burst in a wireless communication system, and an apparatus and method for generating a concatenated data unit during transmission. If a reception end receives the burst, it determines if each data of the burst is a header of the data unit, such that it can separate the data unit from the burst. A transmission end designates individual starting points of data units to be equal to an integer multiple position of a predetermined size, and constructs a concatenated format of the data units, such that it generates the burst.
