Abstract

본 발명은 분산제어 시스팀 전전자 교환기의 디지틀 환경에서 디지틀(ISDN) 가입자가 통화중에 기존호를 보류시키고 제3의 호를 발신할 수 있는 전전자 교환기에서 디지틀 가입자 호 보류 방법에 관한 것으로, 전전자 교환기에 응용하므로서 전전자 교환기 제공 서비스의 다양화를 향상 시켰으며 독립된 블럭(DSSC)으로 실현 하므로서 소프트웨어 시스팀의 모듈성(Modularity)을 유지하도록 하여 디지틀 호보류 서비스를 다른 전전자 교환기에 적용(이식)하기에 쉬우며 타 블럭간에도 호처리 기능이 상호 독립성을 갖으며, 기존의 음성교환망(PSTN)과의 연동을 위해서는 망진화 단계에 발맞추어 기존 음성교환망에 수정을 하지 않고 디지틀 호보류(DSSC) 블럭이 처리하도록 실현하므로 종합정보통신망을 상용화 할때 음성교환망과의 순조로운 연동이 이루어질 수 있다.The present invention relates to a method for holding a digital subscriber call in an electronic switch that enables a subscriber (ISDN) to hold an existing call and make a third call in a digital environment of a distributed control system electronic switch. Application to exchanges has improved the diversification of all electronic exchange providing services and realized as independent blocks (DSSC) to maintain the modularity of the software system so that digital homing services can be applied to other electronic exchanges. The call processing function is independent among other blocks, and for interworking with the existing PSTN, the digital call hold (DSSC) block is implemented without modification to the existing voice switching network in accordance with the step of network evolution. Because it realizes processing, smooth linkage with voice switching network can be achieved when commercializing IT network. have.

Claims (1)

CCS(Central Control Subsystem), ASS(Access Switching Subsystem) , INS(Interconnection Net-work Subsystem)의 3개의 서브시스팀을 구비하는 전전자 교환기에 적용되는 호 보류 방법에 있어서, 현재통화중인 가입자로부터 보류 메시지를 받아 디지틀 호보류 처리 블럭으로 서비스 처리 요청을 하고 자신은 소멸되기를 대기하는 제1단계 ; 디지틀 호 보류 서비스 요청을 받은 디지틀 호보류 처리 블럭은 데이타 베이스의 내용을 검색하여 호 보류 서비스가 등록되었는가를 확인하는 제2단계 ; 해당 가입자 회선에 할당된 호 갯수가 설정치 이하, 또는 시스팀 상태가 과부하 상태가 아닌지를 판단하여 호 보류 처리 내의 각 프로세서를 생성시키는 제3단계 ; 디지틀 호 보류 서비스 요청이 적법하게 진행된 경우 호 보류 처리 블럭은 상대 가입자 기본호 제어 블럭으로 부가 서비스 처리 블럭으로의 천이 요청을 하는 제4단계 ; 부가 서비스 처리블럭 천이 확인을 받으면 해당 B 채널을 해제하고 호 보류 요청 가임자에게 호 보류 확인을 통보하여 상대 가입자에게 호보류음을 제공하여 호 보류 완료를 통보하는 제5단계 ; 호 보류를 요청했던 가입자가 보류된 호를 재 통화하고자 할경우 호 재개를 요청하면 B 채널을 재할당해주고 상대 가입자 제어블럭으로 재통화를 통보하고 기본호처리블럭으로 천이요청을 하여 제어천이 확인 통보를 받으면 호 제개 확인 통보후 호 제개를 완료하는 제6단계를 포함하여 이루어지는 것을 특징으로 하는 전전자 교환기에서 디지틀 가입자 호 보류 방법.A call holding method applied to an electronic switch having three subsystems of a Central Control Subsystem (CCS), an Access Switching Subsystem (ASS), and an Interconnection Net-work Subsystem (INS). Receiving a service processing request to the digital call waiting processing block and waiting for itself to be destroyed; A second step in which the digital call hold processing block receiving the digital call hold service request checks the contents of the database to confirm whether the call hold service is registered; A third step of determining whether the number of calls allocated to the subscriber line is less than or equal to a set value, or whether the system state is not overloaded, to generate each processor in the call hold process; A fourth step of making a transition request to a supplementary service processing block to the counterpart party basic call control block when the digital call holding service request is legally processed; A fifth step of releasing the corresponding B channel when receiving the additional service processing block transition confirmation and notifying the call hold requestee of the call holding request adviser by providing the call subscriber with a call holding tone to notify the completion of the call holding; If the subscriber who requested the call hold wants to re-call the held call, if the call is requested to be resumed, the channel is reassigned and the re-call is notified to the other party's control block and the transition request is sent to the basic call processing block. The method of holding a digital subscriber call in an electronic switchgear, characterized in that it comprises a sixth step of completing the call release after receiving notification of the call release confirmation. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
