Method for providing multimedia ring back tone service on internet phone {Method for provide Multimedia Ring Back Tone service over Internet Phone}

The present invention relates to a method for providing a multimedia ring back tone (MRBT) service to a caller on a Voice over Internet Protocol (VoIP) / Multimedia over Internet Protocol (MoIP),

When the called party applies for MRBT service using ARS, Internet, WAP, or other wired / wireless communication media, if the caller using PSTN, mobile phone, or VoIP / MoIP calls the called party, the caller's terminal is waiting for the call connection. Depending on the function supported by the device, the MRBT containing both video and audio is transmitted to the terminal for playback, or the voice RBT is transmitted to the terminal for playback in the conventional manner, and when the called party and the call are connected, the RBT stops playing and the called party and the caller It relates to a system for connecting.

RBT (Ring Back Tone) is the tone that the caller hears until the call connects when the caller calls the called party. However, in this document, the sound source registered by the content provider is used instead of the pulse tone generated by the exchange directly.

At the time when only PSTNs (wired telephones) existed, these RBTs were uniformly generated by PSTN switching stations (FIGS. 1 and 50) and transmitted to PSTN terminals (FIGS. 1 and 52). Even after the appearance of mobile phones and wireless networks, this situation continued for a while, and personalized RBT (CRBT) appeared to be provided by mobile operators to provide contents such as music and comics according to the subscriber's subscription and content application. This has exploded in popularity among users, and since then, existing PSTN operators have introduced it and are currently performing RBT services regardless of wired or wireless.

However, there is no RBT that includes video / audio (Audio + Video) as well as audio at present, and there is no definition for MRBT in protocols commonly used to implement VoIP. It is impossible to introduce.

The present invention has been created to solve the above problems, the object of the present invention is that if the recipient in the VoIP / MoIP to apply for MRBT service using ARS, Internet, WAP, other wired / wireless communication media PSTN or mobile phone , Or when a caller using VoIP / MoIP makes a call to the called party, while waiting for a call connection, the MRBT including both video and audio is transmitted to the terminal for playback or waiting according to the function supported by the caller's terminal device. The present invention provides a configuration of a system for transmitting and reproducing a voice RBT to a terminal and stopping the reproduction of the RBT and connecting the called party and the caller when the called party and the call are connected.

First of all, the term GateKeeper used in this document is used as a general term that refers to a device that provides connection information and address resolution when a VoIP / MoIP terminal connects to another terminal according to general industry recognition. It is not limited to the H.323 protocol of the Telecommunication standardization sector of the International Telecommunications Union (ITU-T), which uses the terminology, and is identical to the proxy server, redirection server, etc. in SIP of the Internet Engineering Task Force (IETF). It is used as a generic name for equipment that performs a similar function. Thus, the scope of this patent is not limited to H.323, but applies to all common VoIP / MoIP systems.

The called party 20 accesses the MRBT service application system 80 using ARS, the Internet, WAP, and other wired / wireless communication media, and the called party registers with his MRBT service in the MRBT service application system 80; Selecting a content to be performed, registering the content selected by the called party to the MRBT server 70 from the MCP 72 (Master Contents Provider) server, and information about the content registered in the MRBT server 70 as a gatekeeper. Store at 30, and caller-including PSTN 52, mobile phones 62, 64, VoIP (10, 12) all-to call the gatekeeper 30 to set up a call to the called party And checking the functions supported by the caller's terminals 10, 12, 52, 62, and 64 at the gatekeeper 30, and if the tester's terminal has the image receiving and displaying function (10, 64, the MRBT is transmitted from the MRBT server 70 to the terminal, and the terminal of the sender receives the image. And when there is no display function (12, 52, 62), transmitting the general RBT from the MRBT server 70 to the terminal, and stopping the transmission of the RBT / MRBT when the caller and the receiver are connected. Characterized in that made.

In the present invention, the step of performing a conversion function for the video call connection with WCDMA, EV-DO, which is a wireless network protocol capable of making a video call, to the gateway 40 used when making a call connection with an existing PSTN network and a wireless network. Characterized in that made.

In the present invention, characterized in that the MRBT further comprises the step of selectively transmitting to the sender the image of various sizes and compression rates according to the available bandwidth of the sender.

According to the present invention made as described above, when the caller makes a call to the called party subscribed to the MRBT service, the user or the company is promoted by showing or hearing the RBT made of voice or video / audio according to the function of his terminal while waiting for the call to be connected. I can express individuality.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In addition, this embodiment does not limit the scope of the present invention, but is presented by way of example only.

1 is a block diagram schematically illustrating a system to which a method for providing MRBT service over VoIP / MoIP according to the present invention is applied.

As shown here, the called party connects to the MRBT service application system 80 to apply for the MRBT service using ARS, the Internet, WAP, and other wired / wireless communication media. When the user selects the content to be used as his MRBT according to the guidance of the MRBT service application system 80, the content registered from the MCP server 72 is registered in the MRBT server 70 and the contents registration history is stored in the gatekeeper 30. do. Then, when a call is requested from the caller terminal (10, 12, 52, 62, 64) to the caller terminal 20 to establish a call to the gatekeeper 30, the gatekeeper 30 is the caller terminal (10, 12, 52, 62, and 64 checks the functions supported by the MRBT server 70 and transmits the RBT or MRBT registered by the called party to the caller, and stops the RBT or MRBT transmission when the caller is connected with the called party.

This will be described in detail with reference to a flowchart for describing a method of providing an MRBT service over VoIP / MoIP illustrated in FIG. 2.

First, the called party connects to the MRBT service application system 80 to apply for the MRBT service using ARS, the Internet, WAP, and other wired / wireless communication media. (S10)

The MRBT service application system introduces the content to the called party in a unique way, and the called party selects the desired content.

When the user selects the content in the MRBT service application system, content registration is performed from the MCP server 72 to the MRBT server 70. (S14)

The information about the contents registered in the MRBT server 70 is stored in the gatekeeper 30 again (S16).

Subsequently, the call request is made to the gatekeeper 30 to establish a telephone connection from the caller terminal 10, 12, 52, 62, 64 to the caller terminal 20. (S18)

Upon receiving the call setup request, the gatekeeper 30 checks the functions supported by the caller terminal 10, 12, 52, 62, or 64 (S20).

If there is a video reception and display function (10, 64), the MRBT is transmitted from the MRBT server 70 to the caller terminal (10, 64) (S22)

 If there is no image reception and display function (12, 52, 62), transmission of the general RBT from the MRBT server 70 to the caller terminal (12, 52, 62) starts (S24).

After that, the RBT / MRBT is played back until the call connection is established between the calling party terminals 10, 12, 52, 62, and 64 and the called party terminal 20 (S26, S28). do. (S30, S32)

As described above, the present invention promotes itself or a company by showing or hearing an RBT made of voice or video / audio according to its terminal function while waiting for a call to be connected when the caller makes a call to a called party subscribed to the MRBT service.
