본 발명은 전전자교환기에서 전송매체요구정보에 의한 루팅제어방법에 관한 것으로, 보다 상세하게는 서비스 액세스 매체별 전송속도에 따라 다양한 중계자원을 할당할 수 있도록 하는 루팅제어방법에 관한 것이다. The present invention relates to a routing control method based on transmission medium request information in an electronic switchgear, and more particularly, to a routing control method for allocating various relay resources according to a transmission speed for each service access medium.                         

현재, TDX-100 전전자교환기에서는 호유형에 따라 중계 루트가 결정되는 루팅제어방식을 사용하고 있다. Currently, the TDX-100 electronic switch system uses a routing control method in which the relay route is determined according to the type of arc.

즉, 음성위주의 PSTN(Public Switched Telephone Network) 중계호인 경우에는 R2 신호용으로 할당된 직통루트(DR;Direct Route) 및 우회루트(AR;Alternative Route)로 루팅되어 호접속이 이루어지는 반면, ISDN(Integrated Service Digital Network) 중계호인 경우에는 ISUP 신호용으로 할당된 ISDN 직통루트(IDR;ISDN Direct Route) 및 우회루트(IAR;ISDN Alternative Route)로 루팅되어 호접속이 이루어진다.That is, in the case of voice-oriented public switched telephone network (PSTN) relay calls, calls are established by routing to direct routes (DRs) and bypass routes (ARs) allocated for R2 signals, whereas ISDN (Integrated) is established. In case of a service digital network (RSN) relay call, a call connection is made by routing to an ISDN direct route (IDR) and an ISDN alternative route (IAR) allocated for ISUP signaling.

그리고, ISDN 직통루트(IDR)의 1차 루트는 ISUP 중계선으로 할당하고 우회루트로는 R2 신호용 중계선을 할당하도록 되어 있다.The primary route of the ISDN direct route (IDR) is allocated to the ISUP relay line, and the bypass route is allocated to the relay line for the R2 signal.

이때, ISDN 음성호는 ISUP 또는 R2 중계선을 경유하더라도 호 접속이 가능하지만, ISDN 데이터호의 경우에는 ISUP 중계선이 아닌 우회루트로 할당된 R2 신호용 중계선을 경유하게 되면 ISDN 셋업(SETUP) 메시지내의 정보 전달이 불가능하여 호접속이 이루어지지 않는다.In this case, the ISDN voice call can be connected to the call even through the ISUP or R2 relay line.However, in the case of ISDN data call, if the ISDN voice call is routed through the R2 signaling relay line assigned as a bypass route, it is not possible to transmit information in the ISDN setup message. It is impossible to make a call connection.

따라서, 이러한 문제점은 최근들어 수요가 급증하고 있는 인터넷, 고속 화상서비스 등과 같은 액세스 매체별 전전자교환기에서의 중계선 자원 할당에 병목 현상을 초래함은 물론 불완료 호접속을 발생시키는 요인으로 작용하고 있다.Therefore, such a problem is a bottleneck in allocating relay line resources in an electronic switchboard for each access medium such as the Internet and high-speed image service, which are rapidly increasing in demand, and also cause an incomplete call connection. .

이에, 본 발명은 상술한 종래의 문제점을 해결하기 위해 이루어진 것으로, 발신 전송매체를 특성별로 분류하고 그 분류된 전송매체별로 별도의 루팅경로를 제 공할 수 있도록 하는 전전자교환기에서 전송매체요구정보에 의한 루팅제어방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above-described problems. The present invention provides a transmission medium request information in an all-electronic exchange that enables the transmission medium to be classified by characteristics and to provide a separate routing path for each classified transmission medium. The purpose is to provide a routing control method.

상기한 목적을 달성하기 위한 본 발명의 바람직한 실시예에 따른 전전자교환기에서 전송매체요구정보에 의한 루팅제어방법에 의하면, According to the routing control method by the transmission medium request information in the electronic switch according to a preferred embodiment of the present invention for achieving the above object,

참조부호 30은 각각의 TMR 시퀀스에 대해여 특성별로 분류되는 전송매체별 루트시퀀스를 저장하고 있는 전송매체별 루팅정보테이블로서, 상기 전송매체별 루팅정보테이블에 저장되는 각 전송매체별 루트시퀀스에는 직통루트에 대한 루트시퀀스와 그 직통루트로의 데이터전송이 불가능할 경우 경유되어지는 우회루트에 대한 루트시퀀스가 저장되어 있다.Reference numeral 30 denotes a routing information table for each transmission medium storing route sequences for each transmission medium classified by characteristics for each TMR sequence, and is directly connected to the route sequence for each transmission medium stored in the routing information table for each transmission medium. The route sequence for the route and the route sequence for the bypass route to be routed when data transmission to the direct route is impossible.

이하, 첨부된 도 2에 도시된 플로우차트를 참조하여 본 발명의 실시예에 따른 전전자교환기에서 전송매체요구정보에 의한 루팅제어방법의 과정을 상세하게 설명한다.Hereinafter, a process of a routing control method based on transmission medium request information in an all-electronic exchange according to an embodiment of the present invention will be described in detail with reference to the flowchart shown in FIG. 2.

TDX-100 전전자교환기에서 PSTN 및 ISDN 가입자 유형별 호처리 블럭(10) 또는 중계 호처리 블럭(10)으로부터 루팅요구신호가 전송되면(S10), 루팅제어부(40)는 그 루팅요구신호에 포함된 전송매체특성정보와 TMR시퀀스를 분석하여 상기 TMR시퀀스가 기등록된 상태인가를 판단한다(S12).When a routing request signal is transmitted from the call processing block 10 or the relay call processing block 10 for each PSTN and ISDN subscriber type in the TDX-100 switchboard (S10), the routing controller 40 is included in the routing request signal. The transmission medium characteristic information and the TMR sequence are analyzed to determine whether the TMR sequence is already registered (S12).

상기 판단결과 상기 TMR시퀀스가 등록되지 않은 것으로 판단되면(S12에서 No) 루팅요구신호를 전송한 블럭으로 실패(Fail)메시지를 전송한 후 신호를 수신하기 위한 대기상태로 천이하고(S13), 상기 TMR시퀀스가 등록된 상태로 판단되면(S12에서 Yes) 상기 전송매체별 루팅정보테이블(30)을 엑세스하여 상기 루팅요구신호에 포함되어 전송된 전송매체특성정보에 해당하는 루트시퀀스를 추출한다(S14).If it is determined that the TMR sequence is not registered (No at S12), a failure message is transmitted to a block that has transmitted a routing request signal, and then a transition is made to a standby state for receiving a signal (S13). If it is determined that the TMR sequence is registered (Yes in S12), the routing information table 30 for each transmission medium is accessed to extract a root sequence corresponding to the transmission medium characteristic information included in the routing request signal and transmitted (S14). ).

특히, 여기서 상기 전송매체별 루팅정보테이블(30)에는 TMR시퀀스별로 전송매체특성정보에 따라 직통루트에 해당하는 루트시퀀스와 우회루트에 해당하는 루트시퀀스가 저장되어 있기 때문에, 상기 루팅제어부(40)는 상기 TMR시퀀스와 전송매체특성정보를 질의키로 하여 해당 데이터에 대한 직통루트에 해당하는 루트시퀀스를 추출할 수 있게 된다.Particularly, since the route sequence corresponding to the direct route and the route sequence corresponding to the bypass route are stored in the routing information table 30 for each transmission medium according to the transmission medium characteristic information for each TMR sequence, the routing controller 40 The TMR sequence and the transmission medium characteristic information can be extracted as a query key to extract a root sequence corresponding to a direct route for the corresponding data.

상기한 과정에 의해 루트시퀀스를 추출한 상기 루팅제어부(40)는 그 추출된 루트시퀀스가 상기 PSTN루팅테이블(32)과 상기 ISDN루팅테이블(34)에 저장된 루트시퀀스에 등록된 상태인가를 체크하는데(S16), 그 판단결과, 상기 루트스퀀스가 상기 PSTN루팅테이블(32)과 상기 ISDN루팅테이블(34)에 등록되지 않은 루트시퀀스로 체크되면(S16에서 No) 상기 루팅을 요구한 블럭으로 실패(Fail)메시지를 전송한 후 신호를 수신하기 위한 대기상태로 천이한다(S18).The routing controller 40 extracting the route sequence by the above process checks whether the extracted route sequence is registered in the route sequence stored in the PSTN routing table 32 and the ISDN routing table 34 ( If it is determined that the route sequence is checked as a route sequence not registered in the PSTN routing table 32 and the ISDN routing table 34 (No in S16), the block requesting the routing fails (Fail). After the message is transmitted, the terminal transitions to the standby state for receiving the signal (S18).

그러나, 이와 달리 상기 루트시퀀스가 상기 PSTN루팅테이블(32)과 상기 ISDN루팅테이블(34)에 등록된 루트시퀀스로 판단되면, 상기 단계 S14에서 추출된 루트시퀀스를 근거로 상기 출중계루팅테이블(36)로부터 출중계 루트를 추출하여(S20), 그 추출된 출중계 루트의 상태를 체크하여 정상적으로 동작되는가를 체크한다(S22).In contrast, if the route sequence is determined to be a route sequence registered in the PSTN routing table 32 and the ISDN routing table 34, the outgoing routing table 36 is based on the route sequence extracted in step S14. In step S20, the outgoing route is extracted (S20), and the state of the extracted outgoing route is checked to check whether it is normally operated (S22).

여기서, 해당 전전자교환기에서 중계선상태를 관리하는 블럭인 상태관리블럭(도시 생략)으로부터 제공받는 데이터를 근거로 상기 출중계 루트의 상태의 정상여부를 판단하는데, 상기 상태관리블럭으로부터 제공받는 데이터는 각 루트의 상태가 데이터전송이 가능한 상태인지 아니면 데이터전송이 불가능한 상태인지를 나타낸다. Here, it is determined whether the state of the outgoing route is normal on the basis of the data provided from the state management block (not shown), which is a block managing the relay line state in the electronic switchboard, and the data provided from the state management block The status of each route indicates whether data transmission is possible or not.

한편, 상기 단계 S22에서의 판단결과, 상기 출중계 루트의 상태가 비정상적인 것으로 판단되면(S22에서 No) 상기 S14에서 추출된 루트시퀀스에 우회루트에 대한 루트시퀀스가 존재하는가를 판단한다(S24).On the other hand, if it is determined in step S22 that the state of the outgoing route is abnormal (No in S22), it is determined whether a route sequence for the bypass route exists in the route sequence extracted in S14 (S24).

그 판단결과, 우회루트에 대한 루트시퀀스가 존재하면(S24에서 Yes) 상기 출중계루팅테이블(36)로부터 우회루트에 대한 루트시퀀스를 추출한 다음(S26), 상 기 단계 S22로 진행하여 출중계루트가 정상인가를 판단한다.As a result, if there is a route sequence for the bypass route (Yes in S24), the route sequence for the bypass route is extracted from the outgoing route table 36 (S26), and then proceeds to the above step S22 to the outgoing route. Determine if is normal.

그러나, 상기 단계 S24에서의 판단결과 추출된 루크시퀀스에 우회루트에 대한 루트시퀀스가 존재하지 않으면(S24에서 No) 루팅을 요구한 블럭으로 실패(Fail)메시지를 전송한 후 신호를 수신하기 위한 대기상태로 천이한다(S28).However, if the root sequence for the bypass route does not exist in the extracted luck sequence as a result of the determination in step S24 (No in S24), a wait for receiving a signal after transmitting a fail message to the block requesting routing is performed. Transition to state (S28).

한편, 상기 단계 S22에서의 체크결과 추출된 직통루트의 상태가 정상적인 것으로 판단되거나(S22에서 Yes) 상기 단계 S26에서의 체크결과 추출된 우회루트의 상태가 정상적인 것으로 판단되면(S26에서 Yes) 중계선점유요구정보를 생성하여(S30) 상기 출중계 호처리 블럭(50)로 전송하여 중계선 점유를 요구한다(S32).On the other hand, if it is determined that the state of the direct route extracted as a result of the check in step S22 is normal (Yes in S22) or if the state of the bypass route extracted as the result of check in step S26 is normal (Yes in S26), the relay line is occupied Generate the request information (S30) and transmit to the outgoing call processing block 50 to request the occupation of the relay line (S32).

상기 중계선점유요구정보에는 발신번호, 착신번호, TMR 시퀀스, 출중계 루트정보 등이 포함되어 있다.The relay line occupancy request information includes a calling number, called number, TMR sequence, outgoing route information, and the like.

이어, 상기 출중계 호처리 블럭(50)이 상기 중계선점유요구정보를 근거로 발신 전송매체에 따른 최적경로에 해당하는 출중계루트를 통해 데이터가 전달되도록 한다.Subsequently, the outgoing call processing block 50 transmits data through the outgoing route corresponding to the optimum path according to the outgoing transmission medium based on the relay line occupancy request information.

한편, 본 발명에서는 상기 전송매체별 루팅정보테이블에 저장된 전송매체별 루트시퀀스를 근거로 출중계루트를 결정하기 때문에, ISDN 데이터가 R2중계선으로 경유하는 사례를 배제할 수 있게 된다.On the other hand, in the present invention, since the outgoing route is determined based on the route sequence for each transmission medium stored in the routing information table for each transmission medium, the case where the ISDN data passes through the R2 relay line can be excluded.

이상 설명한 바와 같은 본 발명에 의하면, 발신 전송 매체에 따라 루팅을 처리하여 최적의 신호방식을 점유하므로써 가입자에게 보다 양질의 통화 서비스를 제공할 수 있을 뿐 아니라 ISDN 데이터의 전송속도에 따라 루팅 경로를 다르게 적 용할 수 있으므로 각 ISDN 데이터의 전송속도에 따라 최적의 루팅 데이터를 구성하여 기존에 발생하였던 신호방식 불일치 및 전송 속도 불일치 때문에 발생되었던 불완료호를 최소화하여 시스템의 호완료율을 높이는 것을 효과가 있다.According to the present invention as described above, by processing the routing according to the outgoing transmission medium to occupy the optimal signaling method not only can provide a better call service to the subscriber, but also routing route is different depending on the transmission speed of ISDN data As it can be applied, it is effective to increase the call completion rate of the system by minimizing the incomplete call generated by the existing signaling method mismatch and transmission rate mismatch by configuring the optimal routing data according to the transmission speed of each ISDN data.
