This invention is about WCTS Server System, WCTS Terminal and Method to provide Caption Telephone Service. By using voice in wireless and data network, WCTS Sever System provides Wireless Captioned Telephone Service, WCTS), which is one of Telecommunication Relay Service Types. This invention provides convenience by providing the same method of non-handicapped person with WCTS terminal when a deaf person who can speak is speaking on the phone with non-handicapped person. On the other hand, this invention also provides the method of direct dialing to a deaf person who can speak, not the method of indirect dialing that uses representative number of relay center. |

1. A WCTS Server System comprising:
a) a Wireless Captioned Telephone Service (WCTS) terminal, b) a WCTS Terminal Interface that establishes a First Voice Traffic Path and a First Caption Traffic Path by linking with the WCTS terminal; c) a Network Interface that establishes a Second Voice Traffic Path by linking with the other user's terminal; d) a Relay Center Interface that establishes a Third Voice Traffic Path and a Second Caption Traffic Path by linking with a Relay Center; and e) a Handler Part that handles at least one of said First Voice Traffic Path, said First Caption Traffic Path, said Second Voice Traffic Path, said Third Voice Traffic Path and said Second Caption Traffic Path;
wherein the WCTS terminal comprises: i) a dialing part; ii) an operation system part; iii) a communication module part; iv) a monitoring part; and v) a WCTS application part;
wherein the dialing part is linked to the communication module part by using the operation system part and operates when an user calls or receives calls, wherein the state of communication of the communication module part and events produced by the dialing Part during receiving or transferring calls are transferred to the monitoring part through the operation system part, wherein the monitoring part executes the start and end of WCTS application part by using the events, wherein the WCTS application part comprises an application program for the reception of WCTS service, which is executed by the monitoring part, wherein after the WCTS application part is executed, the WCTS application part is connected to the WCTS server system by using the communication module part through the operation system part, and receives and transmits voice data or caption data literated from voice data;wherein the WCTS application part comprises: 1) a user entry part processing user's entry; 2) a display part displaying letters entered by user or caption data received from the WCTS server system; 3) a control part controlling action of the program of the WCTS application part; and 4) an event handler part that is linked with the operation system part;
wherein the event handler part transfers events related to voice call among events received from the operation system part and controlling messages from the WCTS server system to the control part, and transfer the caption data to the display part, wherein the display part expresses the delivered caption data, wherein the user entry part displays data comprising letters entered by a user at the display part and simultaneously transfers the data through the event handler part to the WCTS Server System, and delivers a link control message with WCTS Server System by the user's entry to the control part, thereby executing link-control of the WCTS application part and the WCTS Server System;wherein the WCTS Server System controls said WCTS Terminal Interface, said Network Interface, said Relay Center Interface and said Handler Part, receives voice traffic from said other user's terminal through above said Second Voice Traffic Path, transfers said voice traffic to above mentioned Relay Center through said Third Voice Traffic Path, receives caption data produced from said voice traffic from said Relay center through said Second Caption Traffic Path, and transfers said voice traffic through said First Voice Traffic Path and said caption data through said First Caption Traffic Path to said WCTS terminal. |
