Abstract

본 발명은 일반 가입자측의 접속정보 상태에 관계없이 음성/비음성 정보 서비스가 가능하도록 한 디지탈 셀룰러 시스템의 비음성 정보 서비스장치에 관한 것이다.The present invention relates to a non-voice information service apparatus of a digital cellular system that enables voice / non-voice information service regardless of the state of access information of a general subscriber.

이를 위하여 기존의 디지탈 셀룰러 시스템 내에 디지탈 신호 처리가 가능한 캐리어 신호 검출기, 모뎀 및 팩스복조부와 프레이머를 부설하고 디지탈 셀룰러 단말기에도 모뎀 및 팩스 변조부와 디 프레이머를 부설함으로써 간단한 디지탈 회로 구성에 의하여 일반 가입자가 모뎀이나 팩스등으로 디지탈 셀룰러 시스템의 단말기와의 통신을 원활하게 수행하는 동시에 디지탈 셀룰러 시스템으로부터 제어를 받지 않고도 해당 채널부에서 자동 판별하여 분산처리 하므로 시스템 효용성을 향상시킬 수 있도록 한 것이다.To this end, by installing a carrier signal detector, a modem, a fax demodulator, and a framer capable of digital signal processing in an existing digital cellular system, a modem, a fax modulator, and a deframer are also installed in a digital cellular terminal. The system efficiently improves system efficiency by automatically communicating with the terminal of the digital cellular system through a modem or a fax, and automatically distinguishing and distributing it in the corresponding channel unit without being controlled by the digital cellular system.
