Next, it is assumed that an operation indicating release of hold is performed in the Internet telephone terminal A (901) on the hold side in the hold state. In this case, the Internet telephone terminal A (901) stops reading the compressed hold sound data (G.729) (912) and restarts the input from the microphone (905). At the same time, it switches to the sound of the Internet telephone terminal B (902) that has received the reproduction from the speaker (906). As a result, the speaker (910) of the Internet telephone terminal B (902), which was the holdee, outputs the signal from the Internet telephone terminal A (9).

02), the voice input from the microphone (909) is reproduced, the voice communication state is restored, and the hold state is released.

FIG. 4 shows a second embodiment of the present invention.

This embodiment is an example in which a hold command is transmitted at the time of hold.

An Internet telephone terminal A (1001) and an Internet telephone terminal B (1002) are connected to the Internet. Internet telephone terminal A (10
01) includes a mouse (1003) and a keyboard (100
4), a microphone (1005), and a speaker (1006) are connected. Internet telephone terminal A (1001)
Is "129.60.10.1". Further, a mouse (1007), a keyboard (1008), a microphone (1009), and a speaker (1010) are also connected to the Internet telephone terminal B (1002). The IP address of the Internet telephone terminal B (1002) is "129.60.10.2". Further, the Internet telephone terminal A (1001) receives the uncompressed hold sound data 1 (1011) and the hold sound data 2 (1011).
2), and the hold sound data 1 (1011) is currently set by the hold sound setting unit (1013).
On the other hand, the Internet telephone terminal B (1002) receives the uncompressed hold sound data 1 (1014) and the hold sound data 2 (1
015), and the hold sound data 2 (1015) is currently set by the hold sound setting unit (1016). Also, the Internet telephone terminal A (1001)
As a voice compression encoding method, G.A. 723.1 system and G.72. 7
It is assumed that the Internet telephone terminal B (1002) implements the G.29 system as a voice compression system. 729
It is assumed that only the method is implemented.

First, a call packet is sent from one of the terminals (for example, the Internet telephone terminal A (1001)) to the other terminal (for example, the Internet telephone terminal B (1002)). The Internet telephone terminal B (1002) receiving this transmits an incoming call acceptance packet to the Internet telephone terminal A (1001) of the caller, and shifts to the voice communication state. At this time, both terminals negotiate each other's coding capability. 729, and both are G. 729
The audio data compressed by the system is mutually transmitted and received.

In this voice communication state, when an operation indicating the start of holding is performed by the mouse (1003) or the keyboard (1004) in the Internet telephone terminal A (1001), the Internet telephone terminal A (1001) is operated.
1) is an Internet telephone terminal B (1) which is a communication partner.
002), the hold command is transmitted, the input of the sound input from the microphone (1005) is temporarily stopped, and the compression and transmission processing of the sound data is also temporarily stopped. Then, the holding sound data 1 (1011) set by the holding sound setting unit (1013) is read out and reproduced from the speaker (1006). The Internet telephone terminal B (1002) that has received the hold command temporarily stops the input of the sound input from the microphone (1009), and also temporarily stops the sound data compression and transmission processing. Then, the hold sound data 2 (1015) set in the hold sound setting section (1016) is read and reproduced from the speaker (1010). In this state, both terminals temporarily stop transmitting and receiving voice data, and the Internet telephone terminal A (1001) sets the hold sound data 1 (101
1) is reproduced and the Internet telephone terminal B (1002)
Will play the hold sound data 2 (1015),
It means that it is on hold.

Next, it is assumed that an operation indicating release of the hold is performed in the Internet telephone terminal A (1001) on the hold side in the hold state. In this case, the Internet telephone terminal A (1001) transmits a hold release command to the Internet telephone terminal B (1002), which is the holdee, stops reading the hold sound data 1 (1011), and outputs the speaker (1006). The input from the microphone (1003) and the compression and transmission of the input audio data are restarted while switching the output from the input to the reproduction of the audio received from the other party. The Internet telephone terminal B (1002) of the holdee receiving the hold release command,
The reading of the hold sound data 2 (1015) is stopped, the output from the speaker (1010) is switched to the reproduction of the sound received from the other party, and the input from the microphone (1009) and the compression and transmission of the input sound data are performed. Resume. In this state, in both terminals, the voice input by the other party through the microphone is reproduced from the speaker, and the state returns to the voice communication state.

FIG. 5 shows a hold tone function / configuration diagram in an Internet telephone terminal corresponding to the first configuration example.

In the figure, reference numeral 1 denotes a microphone, 2 denotes a voice input unit,
3 is an A / D converter, 4 is an audio encoder, 5 is a packetizer, 6 is a packet assembler, 7 is an audio decoder, and 8 is a D / D converter.
An A conversion unit, 9 is an audio output unit, and 10 is a speaker, and corresponds to FIG. 1 and FIG.

Reference numeral 20 is an Internet telephone terminal, 21 is a mouse, 22 is a keyboard, 23 is a network interface unit, 24 is a communication control unit, 25 is a control unit, 26 is a hold tone setting unit, and 27 and 28 are Each indicates compression hold sound data, 29 indicates a transmission switching unit, and 30 indicates an output switching unit.

In the case of the first configuration example shown in FIG. 5, the hold-side terminal has hold sound data (compressed hold sound data shown in the drawing) compressed as hold sound data.

FIG. 6 shows a reproduction sequence (1) of a music on hold in an Internet telephone, and FIG.
3 shows a flow (1) of the Internet telephone terminal. This is an example in a case where the compressed on-hold sound data shown in FIG. 4 is used.

First, it is assumed that a connection is established between Internet telephone terminal A and Internet telephone terminal B, and a telephone call is in progress. At this time, in the Internet telephone terminal A, an operation meaning start of holding is performed. This is usually performed by an operation from a mouse or a keyboard. When an operation indicating a hold start is performed, the input of voice from the microphone is temporarily stopped in the Internet telephone terminal A. At the same time, it reads out the compressed on-hold sound data that has been recorded in the Internet telephone terminal in advance, and inputs this from the transmission switching unit to the packetizing unit. As a result, the Internet telephone terminal B, which is the holdee, receives the hold sound data instead of the sound that has been input on the Internet telephone terminal A that has been reproduced up to that time, and reproduces the data. .

To release the hold, an operation indicating release of the hold is performed at the Internet telephone terminal A on the hold side. When an operation meaning release of hold is performed, the Internet telephone terminal A on the hold side resumes input of voice from the microphone. At the same time, the transmission switching unit inputs the encoded data compressed by the audio encoding unit to the packetizing unit, compresses the audio data input from the microphone, and transmits the compressed data to the Internet telephone terminal B. As a result, in the Internet telephone terminal B, the audio data input by the Internet telephone terminal A is reproduced from the reproduction of the hold sound.

In the figure, the Internet telephone terminal A on the holding side does not read out the hold sound data and compresses it at the time of holding, but only reads and transmits the data of the hold sound which has been compressed in advance. It is considered that even a terminal with low performance can be sufficiently processed. Also,
From the standpoint of the hold side, the processing performed on the receiving side is exactly the same, depending only on whether the transmitted data is the data obtained by compressing the sound from the microphone or the compressed hold sound data that has been compressed in advance. That is, the held terminal does not need to change the normal processing.

Also, the apparatus can record compressed coded data for each compressible coding system, and when transmitting the hold sound data, the compressed data compressed by the coding used at the time of the voice communication at that time. Read the held music data and transmit it. Thereby, depending on the communication partner,
Even if the coding rules are different, it is possible to transmit appropriate hold sound data.

FIG. 8 is a diagram showing a hold tone function and configuration of an Internet telephone terminal corresponding to the second configuration example. Reference numerals 1 to 28 in the figure correspond to FIG.
/ OFF unit, 32 denotes an output switching unit, 33 denotes a hold command transmitting / receiving unit, and 34 denotes a hold release command transmitting / receiving unit.

In the case of the second configuration example shown in FIG. 8, the on-hold tone data is held at the terminal on the hold side.

FIG. 9 shows a sequence (2) of reproducing a music on hold in an Internet telephone, and FIG. 10 shows a flow (2) of the Internet telephone terminal at this time. This is an example of transmitting and receiving the hold command shown in FIG.

First, it is assumed that a connection is established between Internet telephone terminal A and Internet telephone terminal B, and the telephone is in a call state. At this time, in the Internet telephone terminal A, an operation meaning start of holding is performed. This is usually performed by an operation from a mouse or a keyboard. When the operation indicating the start of the hold is performed, in the Internet telephone terminal A, the input ON / OFF unit temporarily stops the input of the sound from the microphone. At the same time, it sends a hold command to the other party's Internet telephone terminal B,
The output switching unit switches the reproduction of the own terminal from the audio data received from the other party to the hold sound data registered in the own terminal in advance. Upon receiving the hold command, the Internet telephone terminal B temporarily stops the input of the sound from the microphone by the input ON / OFF unit, and at the same time, reproduces the own terminal by the output switching unit from the sound data received from the other party. ,
Switch to the music on hold data registered in the terminal in advance.

To release the hold, an operation meaning release of the hold is performed in the Internet telephone terminal A on the hold side. When an operation indicating release of hold is performed, the Internet telephone terminal A on the hold side transmits a hold release command to the Internet telephone terminal B on the hold side, and at the same time, the input ON / OFF unit outputs a voice from the microphone. Is resumed, and the output switching unit switches from the hold sound read from the reproduction of the own terminal to the audio data received from the other party. In the Internet telephone terminal on the hold side that has received the hold release command, the input ON / OFF section restarts the input of the sound from the microphone, and the output switching section reads the reproduction of the terminal itself from the hold sound that is read out from the other party. Switch to the received audio data, and both return to the audio communication state.

It is also assumed that a plurality of hold sound data can be registered in advance, and a desired hold sound can be set according to the user's preference.

In the figure, neither the hold-side terminal nor the hold-side terminal performs communication of voice data during the hold, and does not perform compression / decompression processing of voice. It is considered processable.

In the above, the Internet telephone communication method and the Internet telephone communication apparatus have been described. However, the Internet telephone communication method can be held in the form of a program, and the present invention also covers a recording medium on which the program is recorded. Is included.

[0040]

As described above, according to the present invention,
On Internet phones, music on hold is reproduced without increasing the processing of the holding side (= sending side),
The held sound (= receiving side) can normally reproduce the held sound.
