Text relay service communication system and method for a real-time transmission of transcribed voice data via a wireless packet network

1. A text relay service communication system for a real time transmission of transcribed voice data via a wireless packet network, comprising:

a text data receiving part for receiving text data generated and sent by a call agent;

a text data transmitting algorithm part for generating dummy text data when the text data receiving part has not received any text data from the call agent for a pre-determined time period; and

a text transmitting part for transmitting the text data and the dummy text data via the wireless packet network;

wherein the text data transmitting algorithm part receives the text data from the text data receiving part and transfers the text data to the text transmitting part;

wherein the text data transmitting algorithm part sends the dummy text data to the text transmitting part;

wherein the pre-determined time period is set by a wireless packet network provider to release wireless resources of the wireless packet network if there is no data transmission transmitted from the text relay service communication system via the wireless packet network.

2. The text relay service communication system of claim 1 , wherein the text relay service communication system is IP-relay or IP-CTS.

3. The text relay service communication system of claim 1 , wherein the dummy text data is the text data last received from the call agent before expiration of the pre-determined time period.

4. The text relay service communication system Of claim 1 , wherein the dummy text data is a keepalive signal used by the wireless packet network provider to prevent network sessions from being broken.

5. A device for receiving transcribed voice data in real time from a text relay service communication system via a wireless packet network, comprising:

a text data transmitting algorithm part for generating dummy text data when the device has not received any text data from the text relay service communication system for a pre-determined time period; and

a text transmitting part for transmitting the dummy text data via the wireless packet network;

wherein the pre-determined time period is set by a wireless packet network provider to release resources Of the wireless packet network if there is no data transmission between the device and the text relay service communication system via the wireless packet network.

6. The device of claim 5 , wherein the text relay service communication system is IP-relay or IP-CTS.

7. The device of claim 5 , wherein the dummy text data is the text data last received from the text relay service communication system before expiration of the pre-determined time period.

8. The device of claim 5 , wherein the dummy text data is a keepalive signal used by the wireless packet network provider to prevent network sessions from being broken.

9. A method used by a text relay service communication system for a real-time transmission of transcribed voice data via a wireless packet network, comprising:

a step for receiving text data generated and sent by a call agent;

a step for generating dummy text data when no text data has been received from the call agent for a pre-determined time period; and

a step for transmitting the text data and the dummy text data via the wireless packet network;

wherein the pre-determined time period is set by a wireless packet network provider to release wireless resources of the wireless packet network if there no data transmission from the call agent via the wireless packet network.

10. The method of claim 9 , wherein the text relay service communication system is IP-relay or IP-CTS.

11. The method of claim 9 , wherein the dummy text data is the text data last received from the call agent before expiration of the pre-determined time period.

12. The method of claim 9 , wherein the dummy text data is a keepalive signal used by the wireless packet network provider to prevent network sessions from being broken.
