본 발명은 SIP 패킷 통화 서비스에서의 MRF(Multimedia Resource Function)나 H.323 패킷 통화 서비스의 MCU(Multipoint Control Unit)의 기능을 이용한다.The present invention utilizes a function of a multimedia resource function (MRF) in a SIP packet call service or a multipoint control unit (MCU) of an H.323 packet call service.

상기 MRF나 MCU는 미디어의 믹싱(Mixing)과 다중화(Multiplexing)를 위한 변환 또는 생성 기능을 수행한다.The MRF or MCU performs a conversion or generation function for mixing and multiplexing media.

도 1은 본 발명에 따른 시스템의 구성도이다.1 is a block diagram of a system according to the present invention.

발신 또는 착신 이동단말(10,20)은 사용자의 인증/보안 등의 역할을 수행하고, 신호처리 및 무선 송수신을 수행한다.The originating or terminating mobile terminal 10, 20 performs a role such as authentication / security of the user, and performs signal processing and wireless transmission and reception.

링백톤 서버(50)는 가입자가 선택한 음원 코드를 가입자별로 구분하고 MRF(30)나 MCU(40)를 통해 음원을 발신자나 착신자에게 제공한다. The ringback tone server 50 divides the sound source code selected by the subscriber for each subscriber and provides the sound source to the caller or the called party through the MRF 30 or the MCU 40.                     

MRF(30)는 SIP 패킷 통화 서비스에서, MCU(40)는 H.323 패킷 통화 서비스에서 다자간 통화기능 및 음성 믹싱 기능을 수행한다.The MRF 30 performs the multi-party call function and the voice mixing function in the SIP packet call service and the MCU 40 in the H.323 packet call service.

도 2는 본 발명에 따른 배경음 제공 서비스의 호처리 순서도이다.2 is a call processing flowchart of a background sound providing service according to the present invention.

도 2에서는 SIP 화상통화 시스템을 위한 호처리 순서를 예를 들어 설명하고자 한다.In FIG. 2, a call processing procedure for a SIP video call system will be described as an example.

스위치(20)는 이동통신 서비스의 제공에 중요한 망 구성요소로서 이동단말과 PSTN, PSDN, 인터넷 사이에서 모든 호를 교환한다.The switch 20 is an important network component for providing a mobile communication service and exchanges all calls between a mobile terminal, a PSTN, a PSDN, and the Internet.

먼저 발신자는 발신 이동단말(10)을 이용해 착신 이동단말(2)0에 통화를 시도하면 호 요청(INVITE MRF)은 스위치(60)를 통해 MRF(30)로 전달된다(S200,S202).First, when the caller attempts to make a call to the incoming mobile terminal 2 using the calling mobile terminal 10, the call request (INVITE MRF) is transmitted to the MRF 30 through the switch 60 (S200, S202).

상기 MRF(30)는 호 요청(INVITE MRF)을 받아서 다자간 컨퍼런스(CONFERENCE)를 생성한다(S204).The MRF 30 receives a call request (INVITE MRF) and generates a conference conference (S204).

MRF(30)는 그 컨퍼런스 ID에 대한 OK 메시지(200 OK(Conf ID))를 스위치(60)를 통해 발신 이동단말(10)에 전송하고(S206,S208), 발신 이동단말(10)은 그 메시지에 대한 응답 메시지(ACK)를 스위치(60)를 통해 MRF(30)에 전송함으로써(S210,S212), 발신 이동단말(10)과 MRF(30) 사이에 통화로 즉, 미디어 스트림 채널(Media Stream Channel)이 설정된다(S214).The MRF 30 transmits an OK message (200 OK (Conf ID)) for the conference ID to the calling mobile terminal 10 through the switch 60 (S206, S208), and the calling mobile terminal 10 receives the corresponding message. By sending an acknowledgment message (ACK) to the message to the MRF 30 via the switch 60 (S210, S212), a call, i.e., a media stream channel (Media) between the originating mobile terminal 10 and the MRF 30, is transmitted. Stream Channel) is set (S214).

이후 발신 이동단말(10)은 자동으로 컨퍼런스에 초대하는 요청(REFER RingBackTone Server(Conf ID))을 스위치(60)를 통해 링백톤 서버(50)에 보낸다(S216,S218).Thereafter, the calling mobile terminal 10 automatically sends a request (REFER RingBackTone Server (Conf ID)) to invite to the conference through the switch 60 to the ringback tone server 50 (S216 and S218).

링백톤 서버(50)는 요청에 승낙하여(202 ACCEPT) 컨퍼런스에 가입함을 스위 치(60)를 통해 발신 이동단말(10)에 보내게 되면(S220,S222), 링백톤이 MRF(30)를 거쳐서 발신 이동단말(10)에 제공된다(S224,S226).When the ringback tone server 50 accepts the request (202 ACCEPT) and sends a subscription to the conference via the switch 60 to the calling mobile terminal 10 (S220, S222), the ringback tone MRF 30 It is provided to the calling mobile terminal 10 via (S224, S226).

또한, 발신 이동단말(10)은 자동으로 컨퍼런스에 초대하는 요청(REFER Callee(Conf ID)을 스위치(60)를 통해 착신 이동단말(20)에 보낸다(S228,S230).In addition, the originating mobile terminal 10 automatically sends a request (REFER Callee (Conf ID)) to the destination mobile terminal 20 via the switch 60 to invite to the conference (S228, S230).

착신 이동단말(20)은 요청에 승낙(202 ACCEPT)하여 컨퍼런스에 가입함을 스위치(60)를 통해 발신 이동단말(10)에 보내게 되면(S232,S234), 착신 이동단말(20)과 MRF(30) 사이에 통화로 즉, 미디어 스트림 채널(Media Stream Channel)가 설정된다(S236).When the incoming mobile terminal 20 accepts the request (202 ACCEPT) and joins the conference to the calling mobile terminal 10 through the switch 60 (S232, S234), the incoming mobile terminal 20 and the MRF A call route, that is, a media stream channel, is set between 30 (S236).

상기 S224단계 이후에도 계속하여 링백톤 서버(50)에서는 링백톤의 음원을 MRF(30)에 제공하고(S238), 착신 이동단말(20)이 MRF(30)로 연결되는 순간에 MRF는 링백톤을 배경음으로 발신자의 음성과 믹싱하여 착신 이동단말(20)에 전달하고(S240), 링백톤을 배경음으로 착신자의 음성과 믹싱하여 발신 이동단말(10)에 전달한다(S242).After the step S224, the ringback tone server 50 continues to provide the ringback tone sound source to the MRF 30 (S238), and at the moment when the incoming mobile terminal 20 is connected to the MRF 30, the MRF receives the ringback tone. The sound is mixed with the caller's voice as the background sound and transmitted to the called mobile terminal 20 (S240), and the ringback tone is mixed with the caller's voice with the background sound and transmitted to the calling mobile terminal 10 (S242).

이때, 링백톤은 배경음으로 사용되므로 이득 믹싱 파라미터(Gain Mixing Parameter)를 착신자나 발신자의 음성보다 작게 설정하여 음성통화에 방해가 되지 않게 믹싱을 수행한다.At this time, since the ringback tone is used as the background sound, the gain mixing parameter is set to be smaller than that of the called party or the calling party so that the mixing does not interfere with the voice call.

이렇게 해서 음성과 배경음이 믹싱되어 발신자와 착신자 상호 간의 통화중에 같이 감상할 수 있는 음악이 흐르게 된다.In this way, the voice and the background sound are mixed so that music can be listened to together during the call between the caller and the called party.

도 2에서는 SIP 화상통화 시스템을 위한 호처리 순서를 예를 들어 설명하였으나, H.323 화상통화 시스템에도 쉽게 응용할 수 있는 것으로 이 역시 본 발명의 범위에 포함된다고 할 것이다.In FIG. 2, the call processing procedure for the SIP video call system has been described as an example. However, the call processing procedure for the SIP video call system is also easily included in the scope of the present invention.

이상에서와 같이 통화가 연결되지 전까지는 통화연결음(링백톤)으로 제공하던 음원을 착신자가 응답하여 정상적인 통화가 이루어진 경우에는 배경음으로 제공한다.As described above, when a caller makes a normal call in response to a sound source provided as a ring back tone until the call is connected, the sound is provided as a background sound.

이상에서 살펴본 바와 같이 본 발명에 의하면 기존 통화연결음(RingBackTone) 서비스의 업그레이드 개념으로서, 통화중에도 가입자가 선택한 음원을 발신자와 착신자에게 모두 제공할 수 있다.As described above, according to the present invention, as a concept of upgrading an existing RingBackTone service, a subscriber may select a sound source selected by a subscriber to a caller and a receiver during a call.

또한 해당 서비스의 활성화로 음반 및 CP(Content Provider) 등의 콘텐츠 개발에도 이바지할 수 있다.In addition, the activation of the service can contribute to the development of content such as records and content providers (CPs).
