Abstract

본 발명은 휴대용 전화기 등의 개인통신장치에 대하여 단말기에서 기지국으로 제어데이터(Cｏｎｔｒｏｌ Dａｔａ)를 전송함에 있어서 기지국을 통해 할당받은 제어데이터의 프레임번호와 자체적으로 생성한 13MHｚ의 기준클록을 근거로 4명의 가입자에 대하여 업링크 임의접속제어채널(BCCCH)에 대한 스트로브신호를 생성할 수 있도록 된 개인통신용 단말기의 업링크 임의접속제어채널 스트로브신호 발생장치에 관한 것으로, 13MHｚ의 클록신호를 근거로 각 데이터비트에 대응하는 비트동기신호를 생성하고, 이 비트동기신호와 상기 클록신호를 이용하여 156.25비트의 구간을 갖춘 타임슬롯동기신호를 생성하여, 이 타임슬롯동기신호의 계수치와 기준 타임슬롯번호가 일치할 때에 데이터 송수신을 위한 타임슬롯 스트로브신호를 생성함과 더불어 상기 타임슬롯동기신호의 계수에 따라 생성되는 타임슬롯번호를 이용하여 프레임동기신호를 생성하고, 이어 이 프레임동기신호를 계수하여 프레임번호를 생성하게 되며, 이 프레임 번호와 설정된 기준데이터 값에 해당되는 프레임번호를 비교하여 양 데이터 값이 일치하는 기간에 대응하는 타임슬롯 스트로브신호를 출력함으로써 데이터 송수신을 위한 임의접속제어채널 스트로브신호를 생성하게 된다.According to the present invention, in the case of transmitting control data from a terminal to a base station for a personal communication device such as a mobile phone, the present invention is based on a frame number of control data allocated through the base station and a reference clock of 13 MHｚ which is generated by itself. The present invention relates to an apparatus for generating an uplink random access control channel strobe signal of a personal communication terminal capable of generating a strobe signal for an uplink random access control channel (BCCCH) to a subscriber. Each data bit is based on a 13 MH 13 clock signal. Generates a bit synchronization signal corresponding to the B-Synchronization signal, and generates a time slot synchronization signal having a period of 156.25 bits using the bit synchronization signal and the clock signal, and the count value of the time slot synchronization signal and the reference time slot number The time slot strobe signal for data transmission and reception The frame synchronization signal is generated by using the time slot number generated according to the coefficient of the slot synchronization signal, and the frame number is generated by counting the frame synchronization signal, and the frame number corresponding to the frame number and the set reference data value. By comparing the two times, the time slot strobe signal corresponding to the period in which both data values coincide with each other is output, thereby generating a random access control channel strobe signal for data transmission and reception.
