Description

그룹 통신 시스템 및 그룹 통신 방법{A group communication system and a group communication method}A group communication system and a group communication method}

도 1은 종래 기술에 따른 그룹통신에 의한 일대다 통신의 실시 예를 나타낸 예시도이다.1 is an exemplary view showing an embodiment of one-to-many communication by group communication according to the prior art.

도 2는 본 발명의 실시에 따른 일대다 통신 중 귓속말 실시 예를 나타낸 예시도이다.2 is an exemplary view illustrating an embodiment of a whisper during one-to-many communication according to an embodiment of the present invention.

도 3은 본 발명의 구현을 위한 클라이언트와 PoC 서버와의 동작관계를 나타낸 예시도이다.3 is an exemplary view showing an operation relationship between a client and a PoC server for implementing the present invention.

본 발명은 그룹통신 시스템 및 그룹통신 방법에 관한 것으로, 더욱 상세하게는 다자간 통화 중에 그룹 멤버 중 특정 상대에게만 음성 혹은 데이터를 전송할 수 있는 통신 시스템 및 통신 방법에 관한 것이다.The present invention relates to a group communication system and a group communication method, and more particularly, to a communication system and a communication method capable of transmitting voice or data only to a specific counterpart of a group member during a conference call.

보통의 전화 통화는 두 사람이 송신 채널과 수신 채널을 공유하기 때문에 그에 따른 많은 비용을 지불한다. 하지만 그룹통신 서비스는 그룹을 구성하는 다수의 멤버들이 하나의 방송채널을 공유하면서 통신하기 때문에 적은 비용으로 통신할 수 있으므로, 이동통신 단말기 사용자들로부터 많은 관심의 대상이 되고 있다.A normal telephone call pays a lot of money because two people share a transmission channel and a reception channel. However, since the group communication service can communicate at a low cost because a plurality of members constituting the group communicate by sharing one broadcast channel, it has attracted much attention from mobile terminal users.

그룹통신 시스템의 대표적인 예는 PTT(Push-To-Talk) 시스템이다. PTT 시스템은 단일 주파수 또는 전용채널에 의존한다. 그룹에 속한 각 개인이 송신버튼을 누르고 그룹의 다른 참가자와 통신한다. 따라서, 한번에 한 참가자만이 다른 참가자들에게 정보를 송신할 수 있다. 일반적으로 원격회의 시스템에 요구되는 고 비용의 미디어 혼합기(Mixer)를 사용하지 않고도 쉽고 간편하게 그룹에 속한 다른 참가자들과 즉시 그룹통신을 할 수 있을 뿐만 아니라, 회의 참가자들이 많은 경우에 발생하는 누적 배경잡음을 사전에 방지할 수 있는 장점이 있다.A representative example of a group communication system is a push-to-talk system. PTT systems rely on a single frequency or dedicated channel. Each individual in the group presses the Send button and communicates with the other participants in the group. Thus, only one participant can transmit information to other participants at a time. Not only can you easily and immediately communicate with other participants in a group without using the expensive media mixers typically required for teleconferencing systems, but the cumulative background noise that occurs when there are many meeting participants There is an advantage that can be prevented in advance.

도 1은 종래 기술에 따른 그룹통신에 의한 일대다 통신의 실시 예를 나타낸 예시도이다. 도시된 바와 같이, PoC 서버(130)를 통해 클라이언트 A(110)가 동일 통신그룹 내의 멤버들(클라이언트 B,C,D)(121, 122, 123)에게 동일한 음성 데이터(혹은 기타 데이터)를 동시에 전송할 수 있다. 다자간 통화 중에도 그룹통신 멤버들 중 어느 한 멤버에게만 음성 정보 혹은 기타 데이터를 전송하고자 할 경우가 발생할 수 있다. 종래의 기술에 의한 그룹통신에는 이러한 기능을 제공하고 있지 않다. 즉, 다자간 통화에 참여한 각 그룹멤버들에게도 모두 전달되기 때문에 개인적 의견을 주고 받을 수 없는 불편함이 있다.1 is an exemplary view showing an embodiment of one-to-many communication by group communication according to the prior art. As shown, through the PoC server 130, Client A 110 simultaneously transmits the same voice data (or other data) to the members (client B, C, D) 121, 122, 123 in the same communication group. Can transmit Even during a multi-party call, there may be a case where a user wants to transmit voice information or other data to only one of the group communication members. The group communication by the prior art does not provide such a function. In other words, it is inconvenient to give and receive personal opinion because it is delivered to each group member who participated in the multi-party call.

도 2는 본 발명의 실시에 따른 일대다 통신 중 귓속말 실시 예를 나타낸 예시도이다. 먼저 그 구성을 살펴보면, 그룹통신 멤버 중 특정 멤버에게만 패킷을 전송할 수 있는 다수의 클라이언트(클라이언트 A,B,C,D)들로 구성된 통신 그룹(210, 221, 222, 223)과; 상기 통신 그룹을 이루는 클라이언트 사이의 그룹통신을 처리하는 PoC 서버(230)를 포함하여 이루어진다. 본 예시도에서는 클라이언트 A(210)가 그룹 멤버 중 하나의 클라이언트 C(222)에게 귓속말을 하고자 하는 경우를 예로 하고 있다. 그 반대의 경우 혹은 다른 클라이언트 사이의 동작도 동일하게 이루어질 수 있음은 언급의 여지가 없을 것이다. 도시된 바와 같이, 정상적인 일대다 통신의 경우 클라이언트 A(210)가 제공하는 음성 데이터(혹은 기타 데이터)는 PoC 서버(230)를 거쳐 각 클라이언트 B,C,D(221, 222, 223)에게 동시에 전달된다. 만일, 클라이언트 A(210)가 그룹 멤버 중 하나의 클라이언트 C(222)에게 귓속말을 하고자 하는 경우, 클라이언트 A(210)는 토크 버스트 요청 메시지(Talk Burst Request Message)를 PoC 서버(230)에 전송한다. 상기 토크 버스트 요청 메시지는 옵션 필드(option field)를 이용하여 작성된다. 옵션 필드는 옵션ID(Option ID)와 옵션 길이(option length) 및 옵션 값(option value)에 귓말 기능을 포함한다. 귓말 기능을 포함하는 경우 옵션ID 값이 변경된다. 즉, 옵션 ID는 다음과 같은 값을 갖는다.2 is an exemplary view illustrating an embodiment of a whisper during one-to-many communication according to an embodiment of the present invention. First of all, the configuration includes: a communication group (210, 221, 222, 223) composed of a plurality of clients (clients A, B, C, D) capable of transmitting a packet only to a specific member of the group communication members; It includes a PoC server 230 for processing group communication between the clients forming the communication group. In this example, client A 210 wishes to whisper to client C 222 of a group member as an example. It goes without saying that the reverse or the operation between different clients can be the same. As shown, in normal one-to-many communication, voice data (or other data) provided by client A 210 is simultaneously transmitted to each client B, C, D 221, 222, 223 via PoC server 230. Delivered. If the client A 210 wishes to whisper to one of the group members, the client C 222, the client A 210 transmits a talk burst request message to the PoC server 230. . The talk burst request message is written using an option field. The option field includes a word function in an option ID, an option length, and an option value. If the word function is included, the option ID value is changed. That is, the option ID has the following value.

한편, 옵션 값(Option value)에는 상대편 클라이언트의 이름이 포함된다.On the other hand, the option value (Option value) includes the name of the other client.

도 3은 본 발명의 구현을 위한 클라이언트와 PoC 서버와의 동작관계를 나타낸 예시도이다. 세션이 설정되면(S31), 그룹통신의 일원인 클라이언트(210)는 그룹통신 멤버 중 특정 멤버에게만 패킷을 전송하기 위한 토크 버스트 요청 메시지(Talk Burst Request Message)를 생성한다. 이때, 토크 버스트 요청 메시지는 옵션 ID 필드 값을 "3"으로 세팅하고(S32), 옵션 값(option value) 필드에 귓말 대상자명을 입력한다(S33). 완성된 토크 버스트 요청 메시지(Talk Burst Request Message)를 PoC서버로 전송한다 (S34).3 is an exemplary view showing an operation relationship between a client and a PoC server for implementing the present invention. When the session is established (S31), the client 210 as a member of the group communication generates a talk burst request message (Talk Burst Request Message) for transmitting a packet only to a specific member of the group communication members. At this time, in the talk burst request message, the option ID field value is set to "3" (S32), and the word subject name is input in the option value field (S33). The completed talk burst request message is transmitted to the PoC server (S34).

PoC 서버(230)는 수신된 요청 메시지의 옵션ID를 확인하여 분석한다(S35). 만일 옵션 ID 필드의 값이 "3"인 경우에는 귓말 대상자가 저장된 옵션값(option value) 필드에 포함된 값을 저장한다 (S36).The PoC server 230 checks and analyzes the option ID of the received request message (S35). If the value of the option ID field is "3", the word subject stores the value included in the stored option value field (S36).

이어 귓속말을 요청한 클라이언트에게 허가 메시지(TBCP Granted Message)를 전송한다.Subsequently, a TBCP Granted Message is transmitted to the client requesting the whisper.

귓속말 기능의 사용에 대한 승인을 득한 클라이언트(210)는 그룹통신 멤버 중 특정 멤버에게만 제공될 RTP(Real Time Protocol)에 의한 패킷을 PoC 서버(230)로 전송한다 (S37).The client 210 that has obtained the approval for using the whisper function transmits a packet by the Real Time Protocol (RTP) to be provided only to a specific member of the group communication member to the PoC server 230 (S37).

PoC 서버(230)는 귓말 대상자를 확인하고(S38), 해당 멤버에게만 수신받은 패킷을 전송한다(S39).The PoC server 230 confirms the word target person (S38), and transmits the received packet only to the corresponding member (S39).

한편 본 발명의 상세한 설명에서는 구체적인 실시 예에 관해 설명하였으나, 본 발명의 범위에서 벗어나지 않는 한도 내에서 여러 가지 변형 가능함은 물론이다. 일 예로, 본 설명에서는 RTP 패킷으로 표현하였으나 귓속말을 통해 특정 멤버에게만 음성이나 기타 데이터를 전송하는 다양한 형태의 구현이 가능하다. 그러므로 본 발명의 범위는 설명된 실시 예에 국한되어 정해져서는 안 되며 후술하는 특허청구의 범위뿐만 아니라 이 특허청구의 범위와 균등한 것들에 의해 정해져야 한다.Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. For example, in the present description, it is expressed as an RTP packet, but various forms of transmitting voice or other data to only a specific member through a whisper can be implemented. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.

이상에서 설명한 바와 같이, 본 발명은 그룹통신을 수행하는 도중에 세션을 종료하지 않고 특정 멤버에게만 RTP 패킷을 전송할 수 있는 효과를 가질 수 있다.As described above, the present invention may have an effect of transmitting an RTP packet only to a specific member without terminating a session during group communication.
