가입자망간 접속장치의 계층3에서의 호해제 처리방법Call Release Handling Method in Layer 3 of Access Network between Subscriber Networks

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명이 수행되는 계층별 구성도, 제3도는 본 발명에 따른 방법이 수행되는 시스템의 개략적 구성도.1 is a schematic diagram of a hierarchical structure in which the present invention is performed, and FIG. 3 is a schematic diagram of a system in which the method according to the present invention is performed.

Claims (1)

가입자(11a)와 또다른 가입자(11b)가 상호 호를 형성하여 통신을 할 수 있는 가입자망간 접속장치의 계층 3에서의 호해제처리방법에 있어서, 상기 두 가입자가 통화중 상태하에 상기 가입자(11a)로부터 전송되는 절단메세지를 수신시에 상기 가입자(11a)가 운영시스템에 요구하여 스타트된 타이머를 모두 취고 요구하고 가입자 끼리 통화가 가능하게 접속된 가입자(11a)의 “B”채널을 물리적 복구하고 호제어부로 절단 프리미티브를 송신하고 절단 요구상태를 하는 제1단계와, 상기 두가입자가 통화중 상태에서 가입자(11b)의 계층 3이 호제어부로부터 절단 요구신호를 수신시 가입자(11b)의 동작에 의해요구된 타이머를 모두 취소하고 가입자(11b)의 “B”채널을 물리적 복구하며 가입자(11a)의 절단 메시지를 분석하여 가입자(11b)로 송신후 소정타이머를 스타팅하고 절단표시 상태에 들어가는 제2단계와, 상기 제1단계의 절단요구 상태에서 호제어부로부터 복구요구 수신시 상기 가입자(11a)에게 복구요구 메시지를 송신하고 소정시간 타이머 스타팅하고 복구요구 상태로천이하는 제3단계와, 상기 제2단계의 절단표시 상태에서 가입자(11a)로부터 복구 메시지가 수신시 상기 가입자(11a)의 “B”채널을 논리적 복구하고 상기 가입자에게 복구완료 메시지를 송신한후 상기 가입자의 호상태를 논리적하여 휴지상태로하는 제4단계와, 상기 제2단계의 절단표시 상태에서 가입자(11a)로부터 수신시 상기 2단계의 타이머가 취소하고 상기 제3단계의 복구요구 상태로 천이하며, 상기 제2단계의 스타트 타이머가종료수신시상기 제3단계의 복구요구 상태로 천이하는 제5단계와, 상기 제3단계의 복구요구 상태에서 상기 가입자(11b)로부터 복구완료 또는 복구메세지 수신시 상기 제3단계의 소정시간 타이머를 취소하고 상기 가입자(11b)의 “B”채널 및 호를 논리적복구하여 휴지상태로 천이하는 제6단계와, 상기 제3단계의 복구요구 상태의 소정 타이머 시간종료시 첫 번째 검색하여 첫번째 일시에 상기 가입자(11b)로 복구 메시지를 전송하고 상기 타이머와 같은 소정타이머를 스타팅하고 복구 요구 상태로천이하고, 소정 타이머 종료가 첫 번째가 아닐 때 가입자(11b)의 계층 2로 데이터 링크 복구요구하고 상기 가입자(11b)의“B”채널 및 호상태를 논리적 복구하여 휴지상태로 천이하는 제7단계로 이루어짐을 특징으로 하는 방법.A call release processing method at layer 3 of a subscriber network connection device in which a subscriber 11a and another subscriber 11b form a mutual call and communicate with each other, wherein the two subscribers are in a busy state. Upon receipt of the truncated message transmitted from the subscriber), the subscriber 11a requests the operating system to take out all the timers started and physically recover the "B" channel of the subscriber 11a connected to each other. A first step of transmitting a truncation primitive to a call controller and making a truncation request state; and when the two subscribers receive a disconnect request signal from the call controller, the layer 3 of the subscriber 11b is busy. Cancels all timers requested by the user, physically recovers the “B” channel of the subscriber 11b, analyzes the disconnect message of the subscriber 11a, transmits it to the subscriber 11b, and starts a predetermined timer. In the second step of entering the high cutting indication state and the recovery request from the call control unit in the cutting request state of the first step, transmitting a recovery request message to the subscriber 11a, starting a predetermined time timer, and transitioning to the recovery request state. In the third step and the disconnect indication state of the second step, when a recovery message is received from the subscriber 11a, the subscriber B logically recovers the "B" channel of the subscriber 11a and transmits a recovery completion message to the subscriber. A fourth step of logically placing the call state of the call state in the idle state; and the second timer is canceled upon receipt from the subscriber 11a in the disconnection display state of the second step, and transitions to the recovery request state of the third step. A fifth step in which the start timer of the second step transitions to the recovery request state of the third step upon completion of reception; and the subscriber 11b in the recovery request state of the third step. A sixth step of canceling the predetermined time timer of the third step and logically recovering the “B” channel and the call of the subscriber 11b when the recovery is completed or receiving the recovery message, and transitioning to the idle state; When the predetermined timer timeout in the recovery request state is first searched, a recovery message is transmitted to the subscriber 11b at the first date and time, and a predetermined timer such as the timer is started and transitioned to the recovery request state, and the predetermined timer end is not the first time. And a seventh step of requesting data link recovery to Layer 2 of the subscriber (11b) and logically recovering the "B" channel and the call state of the subscriber (11b). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
