Abstract

PURPOSE: A conference call method in a circuit switching network is provided to maintain the conference call of conference callees irrespective of the disconnection of a channel of a conference caller who requests the conference call. CONSTITUTION: A switch 1 retrieves whether a hook-on signal is received from a conference caller(202). If the hook-on signal is not received from the conference caller, the switch 1 retrieves whether a hook-on signal is received from a conference callee(204). If the hook-on signal is received from the conference callee, the switch 1 recognizes that the number of conference callees is decreased by 1(206). The switch 1 judges whether the conference callee is a last conference callee(208). If the conference callee is not the last conference callee, the switch 1 turns off a channel with the corresponding conference callee(216). If the hook-on signal is received from the conference caller, the switch 1 retrieves whether the number of conference callees who currently perform the conference call is one(220). If the number of conference callees is two ore more, the switch 1 performs a conference call sub-routine among the conference callees.

Description

회선교환망에서의 회의 통화 방법Method of Conference Call in Circuit-Switched Network

본 발명은 교환기에 있어서 회의 통화 방법에 관한것으로서, 특히 다수의 교환기로 이루어진 회선교환망내에서 서로 다른 교환기에 속하는 가입자간의 회의통화를 수행하는 회선교환망에서의 회의 통화 방법에 관한 것이다.The present invention relates to a conference call method in a switchboard, and more particularly, to a conference call method in a circuit-switched network that performs a conference call between subscribers belonging to different exchanges in a circuit-switched network consisting of a plurality of exchanges.

일반적으로 교환기에서 회의 통화란 동시에 2가입자이상이 통화를 이루게하는 통화방법을 의미한다. 상술한 회의통화를 위한 일반적인 교환기의 구성과 동작은 본원 출원인에 의해 선출원된 대한민국 특허출원 제91-83428호, 제92-17723호,제92-6538호등에 개시되어 있다. 상술한 교환기들이 서로 결합된 회선교환망내에서 서로 다른 교환기에 가입된 가입자간의 회의통화를 수행하는 종래 회의 통화 방법이 본원출원인에 의해 선출원된 대한민국 특허출원 제93-26121호에 개시되고 있다.In general, a conference call at an exchange means a call method that allows two or more subscribers to make a call at the same time. The construction and operation of the general exchanger for the conference call described above is disclosed in Korean Patent Application Nos. 91-83428, 92-17723, 92-6538, and the like, filed by the applicant of the present application. A conventional conference call method for conducting conference calls between subscribers subscribed to different exchanges in a circuit switched network in which the above-described exchanges are coupled to each other is disclosed in Korean Patent Application No. 93-26121 filed by the present applicant.

제1도는 일반적인 회선교환망에서 회의 통화를 위한 교환기 및 가입자들의 연결일례를 도시하고 있는 연결상태도이다. 상술한 제1도를 참조하여 회선교환망에서의 회의통화방법을 간략히 살펴보면,1 is a connection state diagram illustrating an example of connection of an exchange and a subscriber for a conference call in a general circuit switched network. Referring to FIG. 1, the conference call method in the circuit switched network will be briefly described.

소정 회의그룹정보를 저장하는 적어도 둘 이상의 교환기로 이루어지는 회선교환망에서, 먼저 회의기능을 요구하는 회의발신자(일례로 7450001)가 연결된 주교환기인 교환기1은 상기 회의발신자로부터 회의그룹번호를 수신한다. 이후 상기 교환기1은 상기 수신된 회의그룹번호에 대응하는 회의그룹정보를 검색하여 해당 회의 그룹에 등록된 가입자들의 정보를 억세스하여 자노드에 연결된 가입자인가를 검색한다.In a circuit-switched network consisting of at least two exchanges storing predetermined conference group information, switch 1, which is a main switch to which a conference caller (e.g., 7450001) that requests a conference function is first connected, receives a conference group number from the conference caller. Subsequently, the switch 1 searches conference group information corresponding to the received conference group number, accesses information of subscribers registered in the conference group, and searches for a subscriber connected to the child node.

그리고, 상기 교환기1은 회의그룹에 등록된 가입자들이 자노드 가입자이면 회의 그룹서비스 작업영역에 상기 가입자의 정보 및 통화선로정보를 저장하고 상기 가입자로 상태체크신호를 송출한다. 그러나 상기 회의그룹에 등록된 가입자들이 자노드 가입자가 아니면, 회선교환망으로 연결된 다른 교환기(일례로 교환기2)로 가입자 탐색신호를 송출한다. 이후 상기 회의그룹에 등록된 가입자(일례로 7460001, 7460002)를 연결하고 있는 교환기2가 상기 가입자 탐색신호를 수신하여 해당 가입자들의 존재응답신호를 송출하고, 상기 교환기1은 상기 존재응답신호를 수신하여 상기 교환기2의 정보를 상기 회의그룹 서비스작업영역에 저장하고 상기 교환기2로가입자 상태체크 신호를 송출한다. 그리고, 상기 교환기2는 상기 가입자 상태체크신호를 수신하여 해당가입자들의 통화로상태를 체크하여 해당가입자의 통화로 정보를 포함하는 상태체크응답신호를 출력하고, 상기 해당 가입자들로 호출음을 송출하며, 상기 해당가입자들로부터 호출신호에 응답하는 훅크오프신호가 수신되면 상기 교환기1로 응답신호를 송출한 후 교환기1과 해당가입자들간이 통화로를 연결한다. 이후 상기 교환기1은 상기 상태체크응답신호를 수신하여 해당가입자들의 통화로 정보를 회의그룹서비스작업영역에 저장하고, 상기 교환기2로부터 해당가입자들의 훅크오프신호발생에 응답하는 상기 응답신호가 수신되면, 상기 해당가입자들과 회의 통화로를 연결한다.If the subscribers registered in the conference group are child nodes, the switch 1 stores the subscriber's information and the call line information in the conference group service work area and transmits a status check signal to the subscriber. However, if the subscribers registered in the conference group are not self-node subscribers, the subscriber discovery signal is transmitted to another exchange (eg, switch 2) connected to the circuit-switching network. Subsequently, exchange 2 connecting subscribers (e.g., 7460001 and 7460002) registered in the conference group receives the subscriber discovery signal and transmits the presence response signal of the subscribers, and the exchange 1 receives the existence response signal. The information of the switch 2 is stored in the conference group service work area and a subscriber status check signal is sent to the switch 2. Then, the switch 2 receives the subscriber status check signal, checks the call state of the subscribers, outputs a state check response signal including the call path information of the subscribers, and transmits a ring tone to the corresponding subscribers. When the hook-off signal is received from the subscribers in response to the call signal, the response signal is sent to the switch 1, and the switch 1 and the subscribers connect the call path. Thereafter, the exchange 1 receives the status check response signal and stores information in a conference group service work area of a corresponding subscriber's call, and when the response signal is received from the switch 2 in response to a hookoff signal of the subscribers, The conference call path with the corresponding subscribers.

제2도는 종래 회의통화종료과정을 나타내는 수행흐름도로서, 상기 제1∼2도를 참조하여 종래 회의통화종료방법을 살펴보면, 먼저 102단계에서 교환기1은 회의발신자로부터 훅크온신호가 수신되었는가를 검색한다. 이때 훅크온신호의 수신이 검색되지않으면, 104단계에서 회의통화에 연결된 회의가입자인 회의착신자로부터 훅크온신호가 수신되었는가를 검색한다. 상기 104단계에서 훅크온신호가 검색되지않으면 상기 102단계로 돌아가며, 훅크온신호의 수신이 검색되면 상기 교환기1은 106단계에서 회의착신자의 수가 하나 감소함을 인식하고, 108단계에서 상기 회의착신자가 마지막 회의착신자인가를 판단한다. 이때 마지막회의착신자가 아니면 116단계에서 해당 회의착신자와의 통화로를 오프하고 상기 102단계로 돌아간다. 그러나 상기 108단계에서 마지막회의착신자임이 인식되면, 110단계에서 상기 교환기1은 회의발신자와 회의착신자간의 회의통화로를 오프하며, 112단계에서 회의발신자에게화중음을 송출하고 114단계에서 회의통화를 종료한다.FIG. 2 is a flowchart illustrating a conventional conference call termination process. Referring to FIG. 1 and FIG. 2, the conventional conference call termination method is described. First, in step 102, the exchange 1 searches whether a hook-on signal is received from the conference caller. . In this case, if the reception of the hook-on signal is not detected, in step 104, it is searched whether the hook-on signal is received from the conference called party who is the conference subscriber connected to the conference call. If the hook-on signal is not detected in step 104, the process returns to step 102. If the reception of the hook-on signal is detected, the switch 1 recognizes that the number of the called party decreases by one in step 106, and the caller in step 108 Determine if you are the last conference recipient. In this case, if it is not the last callee, in step 116, the call path with the corresponding caller is turned off, and the flow returns to step 102. However, if it is recognized in step 108 that the last conference party is called, the exchange 1 turns off the conference call path between the conference caller and the conference caller in step 110, sends a call to the conference caller in step 112, and makes a conference call in step 114. Quit.

한편 상기 102단계에서 회의발신자로부터의 훅크온신호가 수신되었으면, 120단계에서 상기 교환기1은 회의통화로를 오프시키고, 122단계에서 모든 회의착신자들에게 회의통화종료메세지를 송출하고 114단계에서 회의통화를 종료한다.On the other hand, if the hook-on signal from the conference caller is received in step 102, the switch 1 turns off the conference call path in step 120, transmits the conference call end message to all conference callers in step 122, and conference call in step 114. To exit.

그러나 상술한 종래의 회의 통화방법은 회의 통화를 요구한 가입자가 회의 통화를 종료하고 오프라인(off line)을 했을 경우, 회의그룹내에 등록된 나머지 가입자들은 모두 화중음을 듣고서 강제로 회의를 끝마쳐야하는 문제점이 있었다. 또한 상술한 문제점을 발생하지않기위해서 상기 종래의 회의통화방법은 회의통화를 요구한 가입자가 전체 회의그룹내에서 통화가 완전히 종료될때까지 대기하여야하는 단점이 있었다.However, in the conventional conference call method described above, when the subscriber who requested the conference call ends the conference call and goes offline, all remaining subscribers registered in the conference group must finish the conference by listening to a busy tone. There was a problem. In addition, in order to avoid the above-mentioned problems, the conventional conference call method has a disadvantage in that the subscriber who requests the conference call has to wait until the call is completely terminated in the entire conference group.

따라서 본 발명의 목적은 회의통화를 요구한 회의발신자의 통화로 절단에 관계없이 회의착신자들이 회의 통화를 유지할 수 있는 회선교환망에서의 회의통화방법을 제공함에 있다.Accordingly, an object of the present invention is to provide a conference call method in a circuit switched network in which conference callers can maintain a conference call regardless of the call disconnection of the conference caller requesting the conference call.

상술한 목적을 달성하기 위한 본 발명은 다수의 가입자들의 회의통화를 이루기위한 통화로연결정보를 기록하고 있는 적어도 둘이상의 교환기로 이루어지는 회선교환망의 회의통화방법에 있어서,The present invention for achieving the above object is a conference call method of a circuit-switched network consisting of at least two exchanges that record the call connection information for achieving a conference call of a plurality of subscribers,

회의통화를 소망하는 회의발신자가 가입된 교환기가 상기 회의발신자의 회의통화요구에 응답하여 상기 통화로연결정보에 의해 회선교환망을 통해 상기 회의발신자와 회의그룹을 이루는 각 가입자들과 통화로를 연결하는 통화로연결단계와,A switch to which a conference caller who desires a conference call joins a call path with each subscriber who forms a conference group with the conference caller through a circuit-switched network based on the channel connection information in response to the conference call request of the conference caller. Connecting with a call step,

상기 교환기가 상기 회선교환망을 통해 상기 회의통화에 착신한 회의착신자로부터 수신한 훅크온신호에 응답하여 상기 가입자의 회의통화로를 절단하는 회의착신자절단단계와,A conference called party cutting step of disconnecting, by the exchange, the conference call path of the subscriber in response to a hook-on signal received from the conference called party receiving the conference call through the circuit switched network;

상기 훅크온신호를 송신한 가입자가 최종 회의착신자이면 상기 교환기가 회의발신자와의 회의통화로를 절단하는 회의발신자절단단계와,A conference caller cutting step of disconnecting, by the exchange, a conference call with a conference caller if the subscriber who sent the hook-on signal is a final conference party;

상기 교환기가 회의 발신자로부터 수신한 훅크온신호에 응답하여 회의착신자의 연결상태를 판단하는 연결상태 판단단계와.A connection state determination step of determining, by the exchange, a connection state of the conference called party in response to the hook-on signal received from the conference caller;

상기 연결상태의 판단결과, 연결된 회의 착신자가 하나이면 상기 회의착신자의 통화로를 절단하는 회의발신자절단단계와,A conference caller cutting step of cutting the call path of the conference called party if the connected conference called party is one;

상기 연결상태의 판단결과, 연결된 회의착신자가 적어도 둘이상이면 상기 회의착신자간의 회의통화를 수행하는 회의착신자회의통화단계로 구성한다.As a result of the determination of the connection state, if at least two connected conference called parties are configured, the conference called party conference call step of conducting a conference call between the conference receivers is configured.

Performance flow chart.

상술한 제1도의 회선교환망 상태도와 상술한 제3∼4도를 참조하여 본 발명의 바람직한 일 실시예의 동작을 살펴보면, 먼저 본 발명에서는 제1도에 도시된 바와 같이 회선교환망을 이루는 교환기들에 각각 가입된 회의통화 가입자들의 회의통화연결과정은 상술한 특허출원 제93-26121호에 개시된 연결방법이 사용될 수 있다. 이러한 연결방법은 상기 특허출원 제93-26121호에 상세히 개시되고 있으므로 이하의 설명에서는 설명을 생략한다. 따라서 상술한 연결과정에 의해 회의통화를 이루고있는 상태에서 제3도에 도시된 202단계에서 교환기1은 회의 발신자로부터 훅크온신호가 수신되었는가를 검색한다. 이때 훅크온신호의 수신이 검색되지않으면, 204단계에서 회의통화에 연결된 회의가입자인 회의착신자로부터 훅크온신호가 수신되었는가를 검색한다. 상기 204단계에서 훅크온신호가 검색되지않으면 상기 202단계로 돌아가며, 훅크온신호의 수신이 검색되면 상기 교환기1은 206단계에서 회의착신자의 수가 하나 감소함을 인지하고, 208단계에서 상기 회의착신자가 마지막 회의착신자인가를 판단한다. 이때 마지막회의착신자가 아니면 216단계에서 해당 회의착신자와의 통화로를 오프하고 상기 202단계로 돌아간다. 그러나 상기 208단계에서 마지막회의착신자임이 인식되면, 210단계에서 상기 교환기1은 회의발신자와 회의착신자간의 회의통화로를 오프하며, 212단계에서 회의발신자에게 화중음을 송출하고 214단계에서 회의통화를 종료한다.Referring to the state of the circuit switched network of FIG. 1 described above and the operation of a preferred embodiment of the present invention with reference to FIGS. 3 to 4 described above, first, in the present invention, as shown in FIG. The conference call connection process of subscribing conference call subscribers may use the connection method disclosed in the aforementioned patent application No. 93-26121. Since this connection method is disclosed in detail in the above-mentioned patent application No. 93-26121, description thereof will be omitted. Therefore, in the state where the conference call is made by the above-described connection process, in step 202 shown in FIG. In this case, if the reception of the hook-on signal is not detected, it is searched in step 204 whether the hook-on signal is received from the conference called party who is the conference subscriber connected to the conference call. If the hook-on signal is not detected in step 204, the flow returns to step 202. If the reception of the hook-on signal is detected, the exchange 1 recognizes that the number of the called party decreases by one in step 206, and the caller in step 208 Determine if you are the last conference recipient. At this time, if the caller of the last meeting is not the caller, the caller is turned off at step 216 and returns to step 202. However, if it is recognized in step 208 that the last conference party is called, in step 210, the switch 1 turns off the conference call path between the conference caller and the conference called party.In step 212, a call is sent to the conference caller and the conference call is received in step 214. Quit.

한편 상기 202단계에서 회의발신자로부터의 훅크온신호가 수신되었으면, 220단계에서 상기 교환기1은 현재 회의통화를 수행하는 회의착신자가 하나인가를 검색한다. 따라서 상기 회의통화자가 하나임이 검색되면, 222단계에서 회의발신자와 회의착신자간의 회의통화로를 오프시키고, 상기 회의 착신자에게 회의통화종료메세지를 송출하고, 214단계에서 회의통화를 종료한다.On the other hand, if the hook-on signal from the conference caller is received in step 202, the switch 1 searches for a single caller currently conducting the conference call. Therefore, when the conference caller is found to be one, in step 222, the conference call path between the conference caller and the called party is turned off, the conference call termination message is sent to the conference caller, and the conference call is terminated in step 214.

그리고 상기 220단계에서 현재 회의통화를 수행하는 회의착신자가 둘이상이면, 230단계에서 회의착신자들간의 회의통화서브루틴을 수행한다.If there are two or more conference callers currently performing the conference call in step 220, the conference call subroutine is performed between the conference callees in step 230.

상기 회의착신자들간의 회의통화서브루틴을 제4도를 참조하여 상세히 살펴보면, 먼저 제4도에 도시된 바와 같이 302단계에서 회의착신자로부터 훅크온신호가 수신되었는가를 검색한다. 이때 훅크온신호가 수신되었어면, 304단계에서 교환기1은 회의착신자가 1감소하였음을 인식하고 306단계에서 현재 회의착신자가 하나인가를 판단하며, 회의착신자가 하나가 아니면, 314단계에서 상기 훅크온신호에 대응하는 해당 회의착신자의 회의통화로를 오프시키고 상기 302단계로 돌아간다. 그러나 상기 306단계의 판단결과 회의착신자가 하나이면, 상기 교환기1은 308단계에서 모든 회의통화로를 오프시키고 잔존하는 회의착신자에게 회의통화종료메세지를 송출하고, 312단계에서 회의통화를 종료한다.Looking at the conference call subroutine between the conference callees in detail with reference to FIG. 4, first, as shown in FIG. 4, it is searched whether a hook-on signal is received from the callee in step 302. In this case, if the hook-on signal is received, the switch 1 recognizes that the conference called party has decreased by 1 at step 304, and determines whether there is currently one called party at step 306, and if it is not one, the hook-on at step 314. The conference call path of the corresponding called party corresponding to the signal is turned off and the process returns to step 302. However, if it is determined in step 306 that there is only one called party, the switch 1 turns off all conference call paths in step 308, sends a conference call end message to the remaining conference callers, and ends the conference call in step 312.

따라서 상술한 바와 같이 본 발명은 회의통화를 요구한 회의발신자가 통화로를 절단하더라도 회의통화로에 연결된 나머지 회의가입자들의 회의통화를 수행할 수 있다는 장점이 있다. 따라서, 회의통화를 이루는 가입자들의 통화로절단이 나머지 회의통화가입자들의 회의통화에 지장을 주지않는다는 이점이 있다.Therefore, as described above, the present invention has an advantage that the conference caller who requests the conference call can perform the conference call of the remaining conference subscribers connected to the conference path even if the conference call is cut off. Therefore, there is an advantage that the call cutting of the subscribers making up the conference call does not interfere with the conference call of the remaining conference call subscribers.
