Abstract

PURPOSE: A call connection method when mutually requesting a call simultaneously is provided to reduce a probability of call failure by flexibly processing calls. CONSTITUTION: A caller terminal requests call setup from a callee terminal(S10). An origination MSC(Mobile Switching Center) requests home location registration from the caller terminal and registers a home location in an origination HLR(Home Location Register)(S20). The origination MSC analyzes an MAP(Mobile Application Part) message and stores a caller's phone number and a callee's phone number in an MAP storing unit(S30). The origination MSC attempts call connection to a termination MSC(S40). The termination MSC checks whether the callee terminal is busy(S50). If the callee terminal is busy, the termination MSC checks whether the callee terminal is requesting call setup(S60). If the callee terminal is requesting call setup, the termination MSC checks a phone number requested for the call setup(S70). If the call setup request phone number is the same as the caller's phone number(S80), the origination MSC does not request call setup from the termination MSC and performs call connection in response to the request signal of the termination MSC(S90).

상호 동시통화 요청시 호연결 방법{METHOD FOR CONNECTING MUTUAL CALLS WHICH ASKED BETWEEN MUTUAL PARTIES}Call connection method for mutual simultaneous call request {METHOD FOR CONNECTING MUTUAL CALLS WHICH ASKED BETWEEN MUTUAL PARTIES}

본 발명은 상호 동시통화 요청시 호연결 방법에 관한 것으로서, 보다 상세하게는 가입자가 상대방에게 전화통화를 위해 호설정을 요구할 때 상대방도 가입자에게 전화통화를 위해 호설정을 요구할 경우 상대방이 요구하는 호설정 요구번호를 확인하여 가입자와 동일할 경우 상대방에게 호설정을 요구하지 않고 상대방의 호설정에 응답하여 호연결이 이루어질 수 있도록 함으로써 호처리의 유연성을 제공하여 호실패되는 경우를 줄일 수 있도록 한 상호 동시통화 요청시 연결방법에 관한 것이다.The present invention relates to a call connection method when requesting a mutual simultaneous call, and more particularly, when a subscriber requests a call setup for a telephone call to the other party, the other party requests a call setup for the telephone call to the other party. If the same as the subscriber by checking the setup request number, the call connection can be made in response to the call setup of the other party without requiring the call setup from the other party, thereby providing flexibility of call processing to reduce the case of the call failure. It relates to connection method when requesting simultaneous call.

최근 휴대폰의 사용이 거의 생활필수품이 됨에 따라 휴대폰을 이용한 전화통화량이 증가하고 있는 실정이다.As the use of mobile phones has become almost a necessity in recent years, the amount of telephone calls using mobile phones has increased.

따라서, 휴대폰을 통해 서로 통화를 하고자 할 경우에도 상호 통화중으로 인해 호설정이 실패되는 경우도 많이 발생하고 있는 상황이다.Therefore, even when attempting to talk to each other through a mobile phone, there are many situations in which call setup fails due to mutual communication.

도 1은 일반적인 호연결 상태를 설명하기 위해 간략하게 도시한 이동통신망 구성도이다.1 is a schematic diagram of a mobile communication network to explain a general call connection state.

여기에 도시된 바와 같이 발신측 단말기(10)는 기지국(미도시)을 통해 발신측 교환기(Mobile Switching Center ; MSC)(20)와 서로 연결되고 발신측 교환기(20)에는 발신측 단말기(10)의 위치 및 상태를 등록하기 위한 발신측 홈위치등록기(Home Location Register ; HLR)(30)가 연결된다. 그리고, 수신측단말기(60)는 기지국(미도시)을 통해 수신측 교환기(40)와 서로 연결되고 수신측 교환기(40)에는 수신측 단말기(60)의 위치 및 상태를 등록하기 위한 수신측 홈위치등록기(50)가 연결된다. 그리고 발신측 교환기(20)와 수신측 교환기(40)는 이동전화망(PLMN : Public Land Mobile Network)(70)을 통해 서로 연결된다.As shown here, the calling terminal 10 is connected to a Mobile Switching Center (MSC) 20 through a base station (not shown) and the calling terminal 10 is connected to the calling switch 20. An originating Home Location Register (HLR) 30 for registering the location and status of the is connected. In addition, the receiving terminal 60 is connected to the receiving side exchange 40 through a base station (not shown) and the receiving side home for registering the position and status of the receiving terminal 60 in the receiving side exchange 40. The location register 50 is connected. The source exchanger 20 and the receiver side exchange 40 are connected to each other via a mobile land network (PLMN) 70.

따라서, 발신측 단말기(10)에서 수신측 단말기(60)와 전화통화를 하기 위해서 발신측 교환기(20)로 호설정을 요구하게 되면, 발신측 교환기(20)에서 발신측 단말기(10)의 위치를 발신측 홈위치등록기(30)에 등록한 후 수신측 교환기(40)로 호연결을 시도하게 된다. 그러면, 수신측 교환기(40)에서 수신측 홈위치등록기(50)로부터 수신측 단말기(60)의 위치 및 상태를 파악한 후 수신측 단말기(60)로 호설정 응답을 요구하게 되고 수신측 단말기(60)에서 응답할 경우 발신측 단말기(10)와 수신측 단말기(60)간에 호연결이 이루어져 전화통화를 할 수 있도록 된다.Therefore, when the caller terminal 10 requests a call setup from the caller switch 20 to make a phone call with the caller terminal 60, the caller terminal 20 positions the caller terminal 10 at the caller terminal 20. Register with the calling party's home location register 30 and then attempts to connect the call to the receiving exchange 40. Then, the receiving side exchange 40 receives the call setting response to the receiving terminal 60 after grasping the position and state of the receiving terminal 60 from the receiving home position register 50 and the receiving terminal 60. In response to the call, a call connection is made between the calling terminal 10 and the receiving terminal 60 so that a telephone call can be made.

그러나, 수신측 교환기(60)에서 수신측 홈위치등록기(50)로부터 수신측 단말기(60)의 위치 및 상태를 확인할 때 수신측 단말기(60)가 다른 가입자와 호연결이 이루어져 전화통화가 이루어지고 있는 상태이거나 호설정을 요구하고 있는 경우라면 발신측 단말기(10)로 통화중 신호를 송출하여 통화중인 것을 알리게 된다.However, when the receiving side exchange 60 confirms the position and status of the receiving terminal 60 from the receiving home location register 50, the receiving terminal 60 makes a call connection with another subscriber and makes a telephone call. If there is a state or call setting request, the calling terminal 10 transmits a busy signal to notify that the call is in progress.

그런데, 발신측 단말기(10)에서 수신측 단말기(60)로 호연결을 시도하려고 할 때 수신측 단말기(60)에서도 발신측 단말기(10)로 호연결을 시도하려고 할 경우에도 수신측 단말기(60)의 상태가 사용중인 것으로 판단되기 때문에 발신측 단말기(10)에서는 통화중 신호를 수신받게 된다.By the way, when the caller terminal 10 attempts to make a call connection from the caller terminal 60 to the caller terminal 60, the receiver terminal 60 also attempts to call the caller to the caller terminal 10. Is determined to be in use, the calling terminal 10 receives the busy signal.

이와 같은 경우에는 상호간에 서로 전화통화를 원하고 있음에도 불구하고 통화중으로 판단되어 호설정이 실패되는 문제점이 있다.In such a case, there is a problem that call setup fails because the call is determined to be busy even though each other wants to make a phone call.

본 발명은 상기와 같은 문제점을 해결하기 위해 창작된 것으로서, 본 발명의 목적은 가입자가 상대방에게 전화통화를 위해 호설정을 요구할 때 상대방도 가입자에게 전화통화를 위해 호설정을 요구할 경우 상대방이 요구하는 호설정 요구번호를 확인하여 가입자와 동일할 경우 상대방에게 호설정을 요구하지 않고 상대방의 호설정에 응답하여 호연결이 이루어질 수 있도록 함으로써 호처리의 유연성을 제공하여 호실패되는 경우를 줄일 수 있도록 한 상호 동시통화 요청시 연결방법을 제공함에 있다.The present invention has been made to solve the above problems, and an object of the present invention is that when the subscriber requests the call setup for the telephone call to the other party, the other party requests the call setup for the telephone call to the subscriber. If the call setup request number is the same as the subscriber, the call setup can be made in response to the call setup of the other party without requiring the call setup from the other party. It is to provide a connection method when requesting mutual simultaneous call.

여기에 도시된 바와 같이 발신측 단말기(10)는 기지국(미도시)을 통해 발신측 교환기(Mobile Switching Center ; MSC)(20)와 서로 연결되고 발신측 교환기(20)에는 발신측 단말기(10)의 위치 및 상태를 등록하기 위한 발신측 홈위치등록기(Home Location Register ; HLR)(30)가 연결된다. 그리고, 수신측 단말기(60)는 기지국(미도시)으로 통해 수신측 교환기(40)와 서로 연결되고 수신측 교환기(40)에는 수신측 단말기(60)의 위치 및 상태를 등록하기 위한 수신측 홈위치등록기(50)가 연결된다. 그리고 발신측 교환기(30)와 수신측 교환기(40)는 이동전화망(PLMN : Public Land Mobile Network)(70)을 통해 서로 연결된다.As shown here, the calling terminal 10 is connected to a Mobile Switching Center (MSC) 20 through a base station (not shown) and the calling terminal 10 is connected to the calling switch 20. An originating Home Location Register (HLR) 30 for registering the location and status of the is connected. In addition, the receiving terminal 60 is connected to the receiving side exchange 40 through a base station (not shown), and the receiving side home for registering the position and status of the receiving terminal 60 in the receiving side exchange 40. The location register 50 is connected. In addition, the source exchange 30 and the receiving side exchange 40 are connected to each other through a mobile land network (PLMN) (70).

그리고, 본 발명에서 호설정을 요구할 경우 전달되는 MAP(Mobile Application Part) 메시지를 분석하여 발신측 전화번호와 수신측 전화번호를 저장하기 위한 발신측 MAP 저장부(35)와 수신측 MAP 저장부(55)를 각각 발신측 홈위치등록기(30)와 수신측 홈위치등록기(50)에 설치한다.In addition, the present invention analyzes a MAP (Mobile Application Part) message transmitted when a call setup request is requested, and includes a calling party MAP storage unit 35 and a receiving party MAP storage unit for storing the calling party number and the receiving party number. 55) are installed in the calling home position register 30 and the receiving home position register 50, respectively.

한편, 본 실시예에서는 발신측교환기(20)와 수신측교환기(40)를 분리하여 설명하고 있으나 하나의 교환기시스템에 의해 구성될 수 있으며 발신과 수신의 상황에 따라 발신측과 수신측은 변경되며 기능에 의해서 분리된다.On the other hand, in the present embodiment, the source exchanger 20 and the receiving side exchange 40 are described separately, but can be configured by one exchange system, and the source and the receiver are changed according to the situation of originating and receiving. Separated by.

그리고 발신측 MAP 저장부(35)와 수신측 MAP 저장부(55)에 저장된 발신측 전화번호와 수신측 전화번호는 호설정이 완료되거나 호실패할 경우에는 삭제하도록 한다.The calling party number and the calling party number stored in the calling party MAP storage unit 35 and the receiving party MAP storage unit 55 are deleted when the call setup is completed or the call fails.

따라서 위와 같이 이루어진 이동통신망에서 작동되는 본 발명에 의한 상호 동시통화 요청시 호연결 방법을 도 3에 도시된 흐름도를 참조하여 설명하면 다음과 같다.Therefore, a call connection method for mutual simultaneous call requests according to the present invention operating in the above-described mobile communication network will be described with reference to the flowchart shown in FIG. 3.

먼저, 발신측 단말기(10)에서 수신측 단말기(60)와 전화통화를 하기 위해 수신측 단말기(60)의 전화번호를 입력한 후 호설정을 요구하게 된다(S10).First, in order to make a telephone call with the receiving terminal 60, the calling terminal 10 inputs a telephone number of the receiving terminal 60, and then requests a call setup (S10).

그러면, 발신측 교환기(20)에서 발신측 단말기(10)로 하여금 홈위치 등록을 요구하게 되며 등록되는 홈위치를 발신측 홈위치등록기(30)에 등록한다(S20).Then, the calling party exchange 20 requests the calling party terminal 10 to register the home location and registers the home location to be registered in the calling home location register 30 (S20).

그리고, 전화를 걸기 위해 전달되는 MAP 메시지를 분석하여 발신측 전화번호와 수신측 전화번호를 발신측 MAP 저장부(35)에 저장한다(S30).Then, the MAP message transmitted to make the call is analyzed and the calling party number and the receiving party number are stored in the calling party MAP storage unit 35 (S30).

그런다음 발신측 교환기(20)에서 수신측 교환기(40)로 호연결을 시도한다(S40).Then, a call connection is attempted from the originating exchange 20 to the receiving exchange 40 (S40).

그러면 수신측 교환기(40)에서 수신측 홈위치등록기(50)에 등록된 수신측 단말기(60)의 위치 및 상태를 확인하여 통화중인가 판단하게 된다(S50).Then, the receiving side exchange 40 checks the position and state of the receiving terminal 60 registered in the receiving home position register 50 to determine whether the call is in progress (S50).

이때 통화중이 아닐 경우에는 수신측 교환기(40)에서 수신측 단말기(60)로 호설정 응답을 요구하게 된다(S120). 그래서 수신측 단말기(60)에서 호설정에 응답을 하게 되면 호연결을 수행하여 전화통화를 할 수 있도록 하지만 호설정에 응답하지 않을 경우에는 호실패가 된다(S90). 그러면 발신측 MAP 저장부(35)에 저장된 발신측 전화번호와 수신측 전화번호를 삭제하게 된다(S100).At this time, if the call is not busy, the call exchange response is requested from the receiving exchange 40 to the receiving terminal 60 (S120). Thus, if the receiving terminal 60 responds to the call setup, it is possible to make a phone call by performing a call connection, but fails to respond to the call setup (S90). Then, the calling party number and the calling party number stored in the calling party MAP storage unit 35 are deleted (S100).

그러나, 위에서 수신측 단말기(60)가 통화중일 경우에는 수신측 단말기(60)도 호설정을 요구하는가 판단한다(S60). 그래서 호설정을 요구하는 것이 아니라 이미 호연결이 이루어져 전화통화가 이루어지고 있을 경우에는 발신측 교환기(20)로 통화중 신호를 송출하게 되고, 이를 수신한 발신측 교환기(20)에서 발신측 단말기(10)로 송신함으로써 통화중 처리가 된다(S110). 이후 발신측 MAP 저장부(35)에 저장된 발신측 전화번호와 수신측 전화번호를 삭제하게 된다(S100).However, when the receiving terminal 60 is in a call from above, it is determined whether the receiving terminal 60 also requests call setup (S60). So, if a call is established by making a call connection instead of requesting a call setup, a call signal is sent to the calling exchange 20, and the calling exchange 20 receives the calling terminal ( 10) the call is processed (S110). After that, the calling party number and the calling party number stored in the calling party MAP storage unit 35 are deleted (S100).

그리고, 위에서 수신측 단말기(60)도 호설정을 요구하는가 판단한 결과 호설정을 요구할 경우에는 수신측 단말기(60)에서 호설정을 요구하는 전화번호가 무엇인가를 수신측 교환기(40)로부터 전달받아 확인한다(S70).In addition, when it is determined that the receiving terminal 60 also requests the call setup from the above, when the call setting is requested, the receiving terminal 60 receives the telephone number requesting the call setting from the receiving exchange 40. Check (S70).

그래서 확인된 호설정 요구 전화번호가 발신측 전화번호와 동일한 번호인가 판단한다(S80).Thus, it is determined whether the confirmed call setup request phone number is the same number as the calling party number (S80).

이때 수신측 단말기(60)에서 호설정을 요구하는 전화번호가 발신측 전화번호와 동일할 경우에는 발신측 교환기(20)에서 수신측 교환기(40)로 호설정을 요구하지 않고 수신측 교환기(40)에서 요구하는 요구신호에 응답하여 호연결을 수행하도록 한다(S90).At this time, if the telephone number requesting call setup in the receiving terminal 60 is the same as the calling telephone number, the receiving side exchange 40 does not require the call setting from the calling side exchange 20 to the receiving side exchange 40. Call connection is performed in response to the request signal requested by S) (S90).

그러나, 수신측 단말기(60)에서 호설정을 요구하는 전화번호가 발신측 전화번호와 다를 경우에는 통화중 처리를 위해 발신측 단말기(10)로 통화중 신호를 송출하게 된다(S110).However, if the telephone number requesting call setup in the receiving terminal 60 is different from the calling telephone number, the busy signal is sent to the calling terminal 10 for in-call processing (S110).

위와 같이 호설정이 완료되어 호연결이 이루어지거나, 통화중일 때 또는 호설정에 응답하지 않아 호실패가 될 경우 발신측 MAP 저장부(35)에 저장된 발신측 전화번호와 수신측 전화번호를 삭제한다(S100).When the call setup is completed as described above and the call is made, or when the call fails when the call is not answered because the call is not answered, the calling party number and the calling party number stored in the calling party MAP storage unit 35 are deleted. (S100).

본 발명에 의한 작동을 실질적인 예를 들어 다시 설명하면 다음과 같다.The operation according to the present invention will be described again with a practical example as follows.

즉, 전화번호가 1111인 A가입자가 전화번호가 2222인 B가입자에게 전화를 걸려고 전화번호 2222를 눌러 호설정을 요구하게 될 때 마침, B가입자도 A가입자에게 전화를 걸려고 전화번호 1111을 눌려 호설정을 요구할 경우 상호간에 동시통화 요청을 하고 있는 것으로 판단됨에 따라 서로 호연결을 수행하여 전화통화가 이루어질 수 있도록 한다.That is, when subscriber A with phone number 1111 makes a call to subscriber B with telephone number 2222 and presses the telephone number 2222 to request call setup, subscriber B also calls subscriber A and dials telephone number 1111. When the call is requested to be pressed, it is determined that simultaneous call requests are made to each other, so that the call can be made by performing a call connection with each other.

상기한 바와 같이 본 발명은 가입자가 상대방에게 전화통화를 위해 호설정을 요구할 때 상대방도 가입자에게 전화통화를 위해 호설정을 요구할 경우 상대방이 요구하는 호설정 요구번호를 확인하여 가입자와 동일할 경우 상대방에게 호설정을 요구하지 않고 상대방의 호설정에 응답하여 호연결이 이루어질 수 있도록 함으로써 호처리의 유연성을 제공하여 호실패되는 경우를 줄일 수 있는 이점이 있다.As described above, according to the present invention, when a subscriber requests a call setup for a telephone call to the other party, the other party checks a call setup request number requested by the other party when the subscriber requests the call setup for a telephone call.
