Abstract: A method for providing a sleep mode and a mobile station thereof are provided to efficiently manage a sleep mode operation in a broadband wireless access system serving downlink traffic. A mobile terminal which is connected to abase station(200) of a mobile communication network through a wireless link to transmit/receive data, and provides a sleep mode comprise the followings: a power supply unit(120) providing power to the mobile terminal; a sleep mode managing unit(130) for managing the sleep mode, the sleep interval within the sleep mode and the listening interval; and a controller(110) controlling the power supply unit based on the first initial-sleep interval of the sleep mode managing unit. The sleep mode managing unit sets the first initial-sleep interval period corresponding to previous integration sleep mode periods pre-stored based on whether the first data of downlink is received from the base station or not.

Abstract: A position detecting method is provided to detect the position of a mobile station by changing the ranging manner used at the existing system, thereby enhancing the efficiency. When the position measurement of a mobile station is needed, the first base station requests the dedicated ranging region for the corresponding mobile station to the adjacent second base station(S10). Thereafter, the second base station allocates and transmits the parameter for the dedicated ranging to the first base station(S12). The first base station allocates the parameter for the dedicated ranging between the corresponding mobile station and the first base station(S14). Thereafter, the first base station inserts the allocated parameter as the TLV(Type/Length/Value) shape into the ranging response message and transmits the ranging response message to the corresponding mobile station(S16). The first base station activates and transmits the dedicated ranging indicator to the defined UL(Up-Link)-MAP to the mobile station(S18). Thereafter, the mobile station transmits the CDMA code included into the ranging response message to the first base station(S20). The first base station measures the timing control value relating to the arrival time of the CDMA code by means of the received CDMA code(S22).

Abstract: A method for managing a sleep interval in a mobile wideband wireless access system is provided to enhance power saving effect by preventing a terminal from unnecessarily awaking from the sleep mode and to reduce delay time of data to be transmitted to the terminal when there occurs a downlink data traffic having a burst feature while the terminal is being in the sleep mode. A method for managing a sleep interval in a mobile wideband wireless access system comprises the following several steps. A base station sets zero to a message which is for notifying existence of a data traffic in case that there is no data which waits for being transmitted during the start sleep interval, and transmits the message to a subscriber terminal(S24). The subscriber terminal enters into the sleep mode(S25). The base station buffers downlink data if there exists the downlink data which waits for being transmitted to the subscriber terminal during the second sleep interval(S26). The base station notifies the subscriber terminal of existence of the buffered data when the subscriber terminal is being operated in a listening mode(S27,S28). The subscriber terminal receives the donwlink data in the listening mode, reduces the sleep interval and enters into the sleep mode(S29). The subscriber terminal maintains the sleep mode for the reduced sleep interval, and switches to the listening mode again(S30). If there is no downlink data to be transmitted to the subscriber terminal, the base station sets zero to the message which is for notifying existence of a data traffic and transmits the message to the subscriber terminal(S31). The subscriber terminal enters into the sleep mode during the sleep interval again(S32).

Abstract: 본 발명은 이동 통신 시스템에서 이동 단말의 핸드오버 방법, 이를 위한 기지국 및 이동 단말에 관한 것이다.
이동 단말이 핸드오버를 수행하기 이전에, 핸드오버가 가능한 인접 기지국들의 리스트를 이동 단말과 서빙 기지국이 서로 공유하도록 하여, 간소화된 제어 메시지의 교환만으로도 고속 이동 환경에서 핸드오버의 수행에 요구되는 지연 시간을 줄일 수 있다. 또한, 서빙 기지국과 이동 단말이 관리하는 핸드오버의 수용이 가능한 인접 기지국 리스트인 활성 기지국 세트를 통해 무선 신호의 품질과 인접 기지국의 자원 상태를 함께 고려하여 관리될 수 있도록 하여, 핸드오버 관련 제어 메시지가 유실되어 미리 핸드오버 준비를 수행하지 못한 타겟 기지국으로 이동 단말이 망 재진입 절차를 시도하는 경우에도 자원 부족으로 인한 핸드오버 실패를 방지하여 핸드오버 성공률을 향상시킬 수 있다.
