If the service cannot be provided, the first step of transmitting a call rejection message 304 to the subscriber together with the cause of rejection 303 and maintaining the busy state 305, if the call-stop service is possible, It stores the call identifier of the request message and the channel in use for resuming the call and cuts the call path (308), and sends a call termination confirmation message to the subscriber (309) to enable replacement or physical delivery of the subscriber station, Send a notification message with the notification identification element 306 informing the processor that the call is busy (307), and drive T307, a three-minute timer for monitoring the subscriber's call resumption request (307); 310, the second step of transitioning to the pause state of the foil (311), the processor receiving the notification message 312 in the busy state (305) performs the following processing without changing the state, and identifies the notification in the message If the information element is checked (313) and the notification message notifying the caller's call resumption, it checks whether or not the voice call is cut (314), the waiting tone being provided (314), and after connecting the disconnected call path (315) to the subscriber In the third step of transmitting a notification message notifying the contents (316), if the notification message notifies the call termination of the other subscriber, it checks whether the voice call is connected and connects the waiting tone (317), and sends a notification message notifying the contents to the subscriber. And a fourth step of transmitting (318) and returning a notification message other than the above to the subscriber as it is (319). 전전자 교환기의 호재개 방법에 있어서, 주프로세서가 호중단 중인 가입자로부터 호재개 메시지를 수신하면(401), 인터페이스 되는 프로세서 번호를선택하고(402), 논리적 라인 번호와 호재개 메시지의 호식별자를 키이로하여 가입자로부터 수신한 호재개 요구가 정상적인 요구인지를 확인하는(403, 404) 제1단계 및 호중단 중인 호에 호재개 요구로 확인되면, 호일시 정지 중인 디지털 회선 가입자 제어의 프로세서로 호재개 요구 메시지를 전송하고(405, 406), 호중단 중인 호가 없거나 등록된 호식별자와 호재개를 요구한 호식별자가 틀릴 때는, 원인 정보요소를 선택하여 가입자에게 호재개 거부 메시지를 전송하는(407, 408) 제2단계를 구비하고 있는 것을 특징으로 하는 호재개 방법.In the method of resuming a call in an electronic switch, when the main processor receives a resumption message from a subscriber who is in a call (401), the processor number to be interfaced is selected (402), and the call identifier of the logical line number and the resumption message is identified. If it is confirmed that the call resumption request received from the subscriber by the key is a normal request (403, 404) and the call resumption request is being called during a call being interrupted, the call is processed by the processor of the digital line subscriber control that is stopped at the time of foil. (405, 406), and when there is no call being interrupted or the registered call identifier and the call identifier requesting resumption are wrong, the cause information element is selected to transmit a call resume rejection message to the subscriber (407). 408) A resumption method, characterized in that it comprises a second step. 제2항에 있어서, 상기 호재개 방법은 주 프로세서로부터 호재개 요구 메시지를 수신하면(501), 가입자의 호재개를 감시하는 타이머 T307를 멈추고(502), 호재개의 요구에 의해 새로운 호로 시작될 수 있도록 가입자로부터 수신한 호참조 번호와단말 식별자를 저장하는(503) 제3단계, 가입자의 호재개 요구가 정상적으로 받아졌음을 알리는 호재개 확인 메시지를 가입자에게 전송하고(504), 절단되었던 통화로를 연결하고(505), 호일시 정지상태에서 상대 가입자의 상태변화를 통지하는통지 메시지 수신을 확인하여(506) 수신된 내용을 상대 가입자에게 통지 메시지로 전송하며(507), 또한 상대측 프로세서에게 가입자의 호재개의 내용을 알리는 통지 메시지를 전송하고(508), 통화중 상태로 천이 하는(509) 제4단계 및 호일시정지 상태에서 호중단 중인 가입자가 3분(T307)이 지나도록 호재개 요구를 하지 않음으로써 CROS(Concur-rent RealtimeOperating Systems)로부터 T307타이머 종료의 메시지를 수신하면(510), 호중단 중인 호식별자를 호재개 대기 상태에서 삭제하고(511), 호재개를 이해 보유하고 있던 채널을 해제한 후(512), 상대 프로세서에게 해제통보를 하고 동작 중이던 프로세서를 멈추고(513, 514), 호일시 정지 상태에서 상대측 프로세서로부터 호해제 통보를 수신하면(515), 가입자의 호재개 요구를 감시하기 위해 동작 중이던 타이머 T307을 멈추고(516), 호중단 중인 호식별자를 호재개 대기 상태에서 삭제하고(517), 호재개를 위해 보유하고 있던 채널을 해제한 훌 동작 중이던 프로세서를 멈추며(518, 519), 호일시 정지 상태에서 상대 프로세서로부터 가입자의 상태변화를 알리는 통지 메시지를 수신하면(520), 호중단 중인 가입자로의 전달을 위해통지 메시지를 저장하고, 호일시 정지 상태를 유지하는(521, 522) 제5단계를 더 구비하고 있는 것을 특징으로 하는 호재개 방법.The method of claim 2, wherein the call resumption method receives a call resumption request message from the main processor (501), stops a timer T307 for monitoring the call resumption of the subscriber (502), and initiates a new call by requesting a call resumption. A third step of storing the call reference number and the terminal identifier received from the subscriber (503), and transmitting a call resumption confirmation message to the subscriber (504) indicating that the subscriber's call resumption request has been normally received (504), and connecting the disconnected call path (505) confirm receipt of the notification message notifying the change of the other subscriber's status in the pause state of the foil (506) and transmit the received contents as a notification message to the other subscriber (507), and also the subscriber's appeal to the other processor. The notification message informing the contents of the dog (508), the transition to the busy state (509) step 4 and the subscriber in the call pause state 3 minutes (T30) 7) when the T307 timer termination message is received from Concur-rent Realtime Operating System (CROS) by not requesting a resumption of the call (510), the call identifier that is being interrupted is deleted from the waiting state of resumption (511), After releasing the channel that has already understood the call resumption (512), it notifies the opponent processor of the release and stops the processor in operation (513, 514), and receives a call release notification from the other processor in the pause state (515). ), The timer T307 which was in operation to monitor the call resumption request of the subscriber is stopped (516), the call identifier that is being interrupted is deleted from the call waiting state (517), and the channel held for resumption is released. When the processor is stopped (518, 519), and receives a notification message indicating the status change of the subscriber from the counterpart processor in the pause state (520), the call to the suspended subscriber And a fifth step of storing (521, 522) a notification message for delivery and maintaining a pause state at the time of foiling. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
