Abstract
본 발명은 가입자 단말기가 한 지역에서 위치변동이 거의 없는 경우 타이밍 어드밴스 조정을 위해 기지국으로부터 전송되어 오는아이들(Idle)타임슬롯의 수신간격을 길게 설정함으로써 전력소비를 줄일 수 있도록 된 아이들 타임슬롯 수신가격을 길게 설저함으로써 전력소비를 줄일수 있도록된 아이들 타임슬롯 수신가격조정을 통한 절전기능을 갖춘 개인통신용단말기에 관한 것으로 GSM 규격에 따른 TDMA방식으로 운용되는 개인통신용 단말기에 있어서 장치전반을 제어하는 제어부와 안테나에의해 수신된 무선주파수신호로부터 본래의 코드신호를 복조하는 복조부, 이 복조부에서 복조되어 출력되는 수신데이터를 디지탈변환하여 수신 전력레벨에 대응하는 데이터값을 출력하는 아날로그/디지탈 변환기 상기 제어부로부터의 소정 제어신호에 따라 이 아날로그/디지탈변환기에서 출력되는 수신전력레벨 데이터를 저장하는 전력레벨 저장부, 기지국과의 동기된 클럭을 근거로 프레임을 계수하는 프레임(frame counter)카우너ㅌ, 및 소정 시간데이터를 생성하는 타이머를 포함하여 구성되고 상기 제어부는 상기 타이머에 의해 계수된 소정 시간구간 동안 전력레벨의 변화가 소정치 이하인 경우 상기 프레임카운터의 계수치를 근거로 아이들(Idle)타임슬롯 수신간격을 평소 간격의 n배수로 설정하여 수신하도록 상기 복조부를 구동제어함을 특징으로 한다.The present invention provides an idle time slot receiving price that can reduce power consumption by setting a receiving interval of idle time slots transmitted from a base station for timing advance adjustment when the subscriber station has little location change in a region. It is a personal communication terminal having a power saving function through an idle time slot receiving price adjustment that can reduce power consumption by setting a long time.The control unit controls the whole device in a personal communication terminal operated by a TDMA method according to the GSM standard. A demodulator for demodulating the original code signal from the radio frequency signal received by the antenna, and an analog / digital converter for digitally converting the received data demodulated and output from the demodulator and outputting a data value corresponding to the received power level. According to a predetermined control signal from A power level storage unit for storing the received power level data output from the analog / digital converter, a frame counter counter for counting frames based on a clock synchronized with the base station, and a timer for generating predetermined time data. The control unit is configured to include an idle time slot receiving interval based on a count value of the frame counter when the change in power level is less than a predetermined value for a predetermined time interval counted by the timer, and by n times the usual interval. And drive control the demodulator to receive.
