Abstract

본 발명은 전전자 교환기에서 비정상 상황 발생에 대한 대지틀 가입자 재시동 방법에 관한 것으로, 전전자 교환기에 가입자 회선, 단말 계층2, 그리고 망의 디지틀 가입자 인터페이스 기능을 담당하는 장치 및 프로세서 등의 비정상 상황이 발생할때 전전자 교환기가 디지틀 가입자 재시동 기능을 수행함으로써 비정상 상황의 즉시 처리에 따르는 신속한 호의 복구 및 호의 복구 상황의 디지틀 가입자에게로의 통보를 수행할 수 있다. 이러한 재시동 기능의 수행으로 위의 비정상 상황에 발생할 수 있는 통화중 호의 먹통, 통화 과금계속, 망과 단말의 호상태 불일치, 그리고 관련된 채널 등의 호자원 장시간 점유의 현상을 피할수 있다. 또한 디지틀 가입자 재시동 절차의 구현에 있어 기존 호처리 프로그램의 수정을 최소화하는 구현방법을 제공함으로써 기능추가에 따르는 프로그램 변경 및 개발비용 최소화의 효과를 얻을 수 있다.The present invention relates to a digital subscriber restart method for occurrence of an abnormal situation in an electronic switchgear, wherein an abnormal situation such as a device and a processor in charge of a digital subscriber interface function of a subscriber line, a terminal layer 2, and a network is provided. When it occurs, the electronic switchboard performs the digital subscriber restart function, so that the prompt call recovery following the immediate handling of the abnormal situation and the digital subscriber of the call recovery situation can be performed. By performing such a restart function, it is possible to avoid the phenomenon of long-term occupation of call resources such as call jamming during call, continuous call charging, mismatch of call status between network and terminal, and related channels. In addition, the implementation of the digital subscriber restart procedure provides an implementation method that minimizes the modification of the existing call processing program, thereby achieving the effect of program change and minimization of development cost due to the addition of functions.
