The present invention relates to a method and a system for a real time transmission of transcribed voice data (“text data”) via a wireless packet network of a telecommunication network (“wireless packet network”) used by Internet Protocol Relay (“IP-Relay”) or Internet Protocol Captioned Telephone Service (“IP-CTS”) for deaf and hard-of-hearing individuals.
The wireless packet networks of the mobile communication network allow data transmission between a server and a client, but if there is no data transmission for a certain period of time, the mobile communication network provider disconnects the wireless link between the server and the client for efficient use of the limited resources of the wireless telecommunication network while keeping the session of the upper layer protocol. This may cause problems such as data transmission delay for IP-Relay or IP-CTS services where a real-time text data transmission is critical for effective communication with deaf and hard-of-hearing individuals. Accordingly, the object of the present invention is to eliminate such delay, caused by the disconnection configuration of the wireless packet networks, for real-time text data transmission by IP-Relay or IP-CTS services in order to provide better service and customer satisfaction.
The use of IP-Relay or IP-CTS services has increased due to a growing population of elderly people with hard of hearing as well as people with congenital or acquired hearing loss, and there is a growing need for the services to be provided to mobile communications devices such as cellular phones or smart phones where such services are limited to a fixed IP terminal of a computer under the wired or WiFi packet network environment. How IP-Relay or IP-CTS service works is as follows. First, a Call Agent (“CA”) transcribes and converts what a hearing-capable user says into text data, and transmits the text data to a hearing-impaired user via IP networks. However, wireless packet networks have limited wireless resources and, they utilize a wireless resource saving feature to release wireless resources while maintaining the upper protocol session if there have been no data transmissions between a server and a client for a pre-set period of time (“T-time period”). Consequently, once the wireless resource saving feature is triggered to release wireless resources while maintaining the upper protocol session, there is a transmission delay and real-time transmission cannot be guaranteed if the server or the client tries to transmit data again because it takes time to re-allocate wireless resources to the link between the server and the client.
Text data is transcribed and generated from the voice of the hearing-capable user and the CA transmits the text data to the hearing-impaired user as part of IP-Relay or IP-CTS services. In
Accordingly, to solve the above problems, a need for a text relay service communication system and method for a real-time transmission of transcribed voice data via a wireless packet network has been present for a long time considering the expansive demands in the everyday life. This invention is directed to solve these problems and satisfy the long-felt need.
The present invention contrives to solve the disadvantages of the prior art. The present invention provides a method and a system for a real time transmission of transcribed voice data via a wireless packet network of a wireless packet network used by IP-Relay or IP-CTS for deaf and hard-of-hearing individuals. The real time transmission has been achieved by generating and sending dummy text data via the wireless packet network before the network releases wireless resources.
Another object of the invention is to provide 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.
Still another object of the invention is to provide a device for receiving transcribed voice data in real trim 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.
Still another object of the invention is to provide 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.
The advantages of the present invention are: (1) the present invention provides a method and a system for a real time transmission of transcribed voice data via a wireless packet network in order to provide the transcribed voice data in real time to deaf and hard-of-hearing individuals; and (2) the present invention provides a means to prevent delay in transcribed voice data transmission transmitted via a wireless packet network.
