Abstract

본 발명은, R2신호방식과 No.7 신호 방식 전화 사용자부(TUP)가 연동(interworking)하는 중계 교환기에서 착신 교환기로부터 발신 가입자 번호의 중계를 요구받으면, 먼저 수신할 수 있는 착신 가입자의 번호 체계(개방형, 고정형)를 조사하고, 번호 체계가 개방형인 경우에는 발신 교환기와의 국간 신호 상태를 조사한다.According to the present invention, when a relay exchange interworking between an R2 signaling system and a No.7 signaling telephone user unit (TUP) is requested to relay an outgoing subscriber number from a terminating exchange, the receiving subscriber number system can be first received. (Open type, fixed type) and, if the numbering system is open type, examine the status of station-to-station signaling with the originating exchange.

국간 신호 상태가 발신 교환기로 수신할수 없는 착신 가입자 번호를 요구하고 있는 상태이면 R2신호 방식의 특성에 따라 발신 교환기로부터 대응 신호를 수신할 때까지 다음 신호를 전송할 수 없으므로 발신 교환기로 발신 가입자 번호의 중계 요구를 할 수 없다. 이 경우에는 착신 교환기로 발신 가입자 번호의 중계 요구를 수용할 수 없음을 알려서 호가 실패되는 것을 방지한다.If the inter-station signaling state requires a called party number that cannot be received by the calling exchange, the next signal cannot be transmitted until the corresponding signal is received from the calling exchange according to the characteristics of the R2 signaling method. Can't make a request. In this case, the incoming exchange is informed that it cannot accept the relay request of the calling party number to prevent the call from failing.

When receiving one incoming call number, translate the station number to the received incoming call number, and if it is determined that the station number translation result is a transit call of another station with the TUP signal, the incoming call number will be occupied by the incoming call number so far. After performing the first step (1 to 5) and the first step (1 to 5) to check whether the outgoing relay line cannot be occupied, the outgoing exchange may be requested by the calling exchange. The second step (6 to 11), and the second step (6 to 11) for transmitting the incoming call number received by occupying the outgoing line to the destination exchange if the incoming call number is received enough to occupy the outgoing line. ) After execution, compare the number of incoming calls received so far with the maximum number of incoming calls that can be received by the relay exchange, and request only the called party to the originating exchange only if the maximum number is not received, and signal the status of the call. After the third step (12, 13) waiting for a signal from the destination exchange in the interlocking state and the third step (12, 13), after receiving the incoming call in the signal interlocking state, the incoming call is sent to the calling exchange and the outgoing call is made. Investigate whether to request an outgoing subscriber number (hereinafter referred to as calling number) to the exchange.If there is no calling number request, the incoming call termination signal is received, the incoming call number is not solved. Requesting the calling party class to receive the call and waiting for the calling party status signal (step 14 to 20), and after performing the third step (12, 13), incoming call When the call request is received from the ventilation, the number of incoming calls that can be received by the relay exchange is compared with the minimum and minimum number (represented as Min in the figure). After the fifth step (21 to 29) and the third step (12, 13) to perform the processing according to the incoming call not received as much as the incoming call state, and receives the incoming call reception completion signal from the destination exchange In step 6, the relay exchange determines whether the incoming call is requested by the calling exchange. If the incoming call is requested, the relay exchange notifies the incoming call with a normal signal. 41), and when the calling party class is received in the calling party receiving state, the calling party waits for the calling party, and when receiving one calling party, the calling party end signal is received. If it is not the end signal, it retransmits the calling request signal to the calling exchange and waits for the calling call. If the ending signal is received, it transmits the calling number received so far to the destination exchange, and processes according to the additional reception as necessary for the request number. And a seventh step (30 to 37) to be carried out. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
