Abstract

Voice data from speech start till mute are transmitted as a section voice file to the opposite side voice data transmitting and receiving system, thus permitting voice data transmission free from voice interruption. By transmitting voice data from the speech start till the mute it is possible to eliminate packet losses in the data transmission channel and perform voice communication in the same voice quality as in the transmitting side. Besides, because of the use of HTTP communication port it is possible to obtain voice communication exceeding the rooter without any special setting.

Claims

1. A voice data transmitting and receiving system for transmitting and receiving voice data as packet data via a network, the system comprising:

a first transmitting and receiving unit which transmits voice data of a communication voice from a detected speech start in said communication voice till a detected mute in said communication voice as a voice file by packet switching; and

a second transmitting and receiving unit which receives the voice data and outputs the received data,

wherein the voice data are transmitted by adding a given notification tone to an end of the voice file, and

wherein the second transmitting and receiving unit waits until a packet containing a transmission right has been received, said transmission right being included with said packet for alternate voice transmission at the end of the voice file.

2. The voice data transmitting and receiving system according to claim 1, wherein the first transmitting and receiving unit divides the voice file into voice file divisions of a predetermined size if the voice file exceeds a predetermined length, and transmits the voice file by adding a header to each voice file division indicating that each voice file division is a division of said voice file, and the second transmitting and receiving unit combines the voice file divisions based on the header.

3. The voice data transmitting and receiving system according to claim 1, wherein the network is a non-QoS guaranteed network.

4. The voice data transmitting and receiving system according to claim 3, wherein the non-QoS guaranteed network is an internet.

10. The voice data transmitting and receiving system according to claim 1, wherein the first transmitting and receiving unit divides the voice file into voice file divisions of a predetermined size if the voice file exceeds a predetermined length, and transmits the voice file by adding a header to each voice file division indicating that each voice file division is a division of said voice file, and the second transmitting and receiving unit combines the voice file divisions based on the header.

11. The voice data transmitting and receiving system according to claim 1, wherein the network is a non-QoS guaranteed network.

12. The voice data transmitting and receiving system according to claim 1, wherein the voice data are transmitted with an HTTP protocol.

5. A voice data transmitting and receiving system for transmitting and receiving voice data as packet data via a network, the system comprising:

a first transmitting and receiving unit which transmits voice data of a communication voice from a detected speech start in said communication voice till a detected mute in said communication voice as a voice file by packet switching; and

a second transmitting and receiving unit which receives the voice data and outputs the received data,

wherein the voice data are transmitted by adding a given notification tone to an end of the voice file, and

wherein the first transmitting and receiving unit judges high packet loss possibility packet data as such and retransmits the high packet loss possibility packet data together with a preceding packet.

6. A voice data transmitting and receiving system for transmitting and receiving voice data as packet data via a network, the system comprising:

a first transmitting and receiving unit which transmits voice data of a communication voice from a detected speech start in said communication voice till a detected mute in said communication voice as a voice file by packet switching; and

a second transmitting and receiving unit which receives the voice data and outputs the received data,

wherein the voice data are transmitted by adding a given notification tone to an end of the voice file,

wherein the first transmitting and receiving unit adds a header to the voice data, and the second transmitting and receiving unit subjects only voice data, in which the header is detected, to voice processing, and

wherein the second transmitting and receiving unit waits until a packet containing a transmission right has been received, said transmission right being included with said packet for alternate voice transmission at the end of the voice file.

7. The voice data transmitting and receiving system according to claim 6, wherein the second transmitting and receiving unit accumulates the received voice data in a recorder, and reproduces the accumulated voice data after the detected mute in the communication voice.

13. The voice data transmitting and receiving system according to claim 6, wherein the voice data are transmitted with an HTTP protocol.

8. A voice data transmitting and receiving system for transmitting and receiving voice data as packet data via a network, the system comprising:

a first transmitting and receiving unit which transmits voice data of a communication voice from a detected speech start in said communication voice till a detected mute in said communication voice as a voice file by packet switching; and

a second transmitting and receiving unit which receives the voice data and outputs the received data,

wherein the voice data are transmitted by adding a given notification tone to an end of the voice file,

wherein the second transmitting and receiving unit accumulates the received voice data in a recorder, and reproduces the accumulated voice data after the detected mute in the communication voice,

wherein the second transmitting and receiving unit waits until a packet containing a transmission right has been received, said transmission right being included with said packet for alternate voice transmission at the end of the voice file.

14. The voice data transmitting and receiving system according to claim 8, wherein the voice data are transmitted with an HTTP protocol.

9. A voice data transmitting and receiving system for transmitting and receiving voice data as packet data via a network, the system comprising:

a first transmitting and receiving unit which transmits voice data of a communication voice from a detected speech start in said communication voice till a detected mute in said communication voice as a voice file by packet switching; and

a second transmitting and receiving unit which receives the voice data and outputs the received data,

wherein the voice data are transmitted by adding a given notification tone to an end of the voice file,

wherein the voice data are transmitted with an HTTP protocol,

wherein the first transmitting and receiving unit transmits the HTTP file by adding a header defined exclusively for voice, and the second transmitting and receiving unit separates the HTTP file containing the voice data and other data from the header in the HTTP file,

wherein the second transmitting and receiving unit waits until a packet containing a transmission right has been received, said transmission right being included with said packet for alternate voice transmission at the end of the voice file.
