Abstract

본 발명은 전전자 교환기에서의 호상태 문의 처리방법에 관한 것으로, 특히 종합정보 통신망의 노드로 사용되는 전전자교환기가 통화중 상태에서 주기적인 디지틀 가입자 호상태 문의 기능을 수행함으로써 가입자 단말장치, 디지틀 가입자 회선, 단말 계층2, 그리고 망의 디지틀 가입자 인터페이스 기능을 담당하는 장치 및 프로세서 등의 비정상 상황으로 발생할수 있는 통화중 호의 먹통, 가입자 단말의 호상태는 통화중이 아니나 망의 호상태가 통화중으로 유지되어 과금에 대한 가입자 민원 증대, 망과 단말의 호상태 불일치, 그리고 관련된 채널 등의 호자원 장시간 점유의 현상을 피할 수 있을 뿐만아니라 디지틀 가입자 호상태 문의 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 method for processing a call state query in an electronic switchgear, and in particular, a subscriber terminal device and a digital device by performing a periodic digital subscriber call state query function while a telephone switcher used as a node of an integrated information communication network is busy. Incoming calls that can occur due to abnormal conditions such as subscriber line, terminal layer 2, and devices and processors that are responsible for the digital subscriber interface functions of the network, and the call state of the subscriber station is not busy but the call state of the network is busy. It is possible to avoid the increase of subscriber complaints about billing, mismatch of call status between network and terminal, and long time occupancy of call resources such as related channels, as well as modification of existing call processing program in the implementation of digital subscriber call status inquiry procedure. Pro by adding features by providing an implementation that minimizes Gram changes and development costs can be minimized.

종합정보 통신망의 노드로 사용되는 전전자 교환기에서 가입자 단말장치의 이상, 디지틀 가입자 보드의 기능이상, 망계층2 처리기의 재시동 또는 비정상, 주변 프로세서인 ISAP(ISDN Subscriber Access Processor)와 ASP(Access SwitchingProcessor)간의 IPC(Inter-Processor Communication)의 일시적인 장애와 같은 비정상 상황이 발생할 때, 그러나, 통화중인 호에 대해 비정상 상황의 발생으로 망이 통화중인 호의 해제 관련 메세지(DISCONNECT, RELEASE, R ELEASE COMPLETE 등) 또는 해제 관련 IPC 시그널을 수신하지 못하게 되면, 망에서의 무한정의 통화중 상태 유지로 인한 통화과금 시간 불일치와 스위치, 메모리, 그리고 CPU 등의 시스템 자원의 낭비가 발생하므로, 전전자 교환기에서 비정상 상황으로 발생할 수있는 호상태 불일치 현상을 조속히 감지하여 망의 자원낭비와 가입자의 통화과금 불일치 민원을 최소화할 수 있는 전전자교환기에서의 호상태 문의 처리방법에 관한 것이다.An abnormality of a subscriber terminal device, a malfunction of a digital subscriber board, a restart or abnormality of a network layer 2 processor, an ISAP (ISDN Subscriber Access Processor) and an access switching processor (ASP), which are peripheral processors, in an electronic switch used as a node of an integrated information communication network. When an abnormal situation occurs, such as a temporary failure of inter-processor communication (IPC) between the two parties, however, an abnormality situation occurs on a busy call, such as a message related to the release of a call on the network (DISCONNECT, RELEASE, R ELEASE COMPLETE, etc.) or Failure to receive the release-related IPC signal can result in an abnormal situation at the electronic switchboard because it can result in call charge time mismatch and waste of system resources such as switches, memory, and CPU due to the indefinite busy state in the network. Promptly detect possible call state mismatch and waste network resources and subscribers' billing Call status inquiries from around the electronic exchange that can minimize the matches complaint relates to the treatment.
