Abstract

A method and a terminal are provided for performing a Teletype/Telecommunications Device for the Deaf (TTY/TDD) service where the wireless terminal changes to a vibration mode when the TTY/TDD service is performed. If a called party number and a call key are input, a call connection request signal is transmitted and a first vibration is generated. A second vibration is generated if a call ready signal is received after the call connection request signal is transmitted. A third vibration is generated if an absence signal is received. Accordingly, the TTY/TDD service can be supported in the wireless terminal without the aid of other external devices, and a hearing-impaired user can immediately recognize a TTY/TDD text reception or transmission state by generating a different vibration when the call connection request signal, the call ready signal, or the absence signal is detected and generating a vibration, text messages, and/or an image when TTY/TDD text messages are received or transmitted during the TTY/TDD service.

Claims

1. A method of performing a Teletype/Telecommunications Device for the Deaf (TTY/TDD) service in a wireless terminal, the method comprising the step of:

changing an established transmission/reception notice mode to a vibration mode when a TTY/TDD service key is input.

2. The method of claim 1, further comprising the step of:

if a called party number is input and a call key is input, transmitting a call connection request signal and generating a first vibration.

3. The method of claim 1, further comprising the step of:

if a call ready signal is received, generating a second vibration.

4. The method of claims 1, further comprising the step of:

if an absence signal is received, generating a third vibration.

5. The method of claim 3, wherein the first vibration and the second vibration comprise a different vibration rating.

6. The method of claim 4, wherein at least one of the first vibration, the second vibration, and the third vibration comprises a different vibration rating.

7. The method of claim 4, wherein each of the first vibration, the second vibration, and the third vibration comprises a different vibration rating.

8. The method of claim 3, wherein the first vibration and the second vibration comprise a different vibration pattern.

9. The method of claim 4, wherein at least one of the first vibration, the second vibration, and the third vibration comprises a different vibration pattern.

10. The method of claim 4, wherein each of the first vibration, the second vibration, and the third vibration comprises a different vibration pattern.

11. The method of claim 3, further comprising, when the first vibration, or the second vibration, or the third vibration is generated, outputting a different image.

12. The method of claim 4, further comprising, when the first vibration, the second vibration, or the third vibration is generated, outputting a different image.

13. The method of claim 4, further comprising, when at least one of the first vibration, the second vibration, and the third vibration is generated, outputting a different image.

18. The method of claim 1.7, further comprising generating a second vibration and outputting a call ready image if a call ready signal is received after the call connection request signal is transmitted.

19. The method of claim 18, further comprising generating a third vibration and outputting an absence image if an absence signal is received.

20. The method of claim 19, wherein each of the first vibration, the second vibration, and the third vibration has a different vibration pattern.

14. A method of performing a Teletype/Telecommunications Device for the Deaf (TTY/TDD) service in a wireless terminal, the method comprising the steps of:

when the TTY/TDD service is performed, changing the wireless terminal to a vibration mode and displaying a TTY/TDD service window; and

if TTY/TDD text messages are input in the displayed TTY/TDD service window and transmitted, generating a vibration.

15. The method of claim 14, further comprising, if TTY/TDD text messages are received, generating a vibration and displaying the received TTY/TDD text messages on the TTY/TDD service window.

16. The method of claim 14, wherein the TTY/TDD service window comprises an input window and a display window.

17. A method of performing a Teletype/Telecommunications Device for the Deaf (TTY/TDD) service in a wireless terminal, the method comprising the steps of:

changing the wireless terminal to a vibration mode when the TTY/TDD service is performed;

if a called party number and a call key are input, transmitting a call connection request signal, generating a first vibration, and outputting a call connection request image.

21. A terminal for performing a Teletype/Telecommunications Device for the Deaf (TTY/TDD) service, the terminal comprising:

a controller which detects or sets operation mode of the terminal; and

a vibration module responsive to the controller to generate a vibration;

wherein, when the operation mode of the terminal comprises performing TTY/TDD service, a transmission/reception notice comprises the vibration.

22. The terminal of claim 21, further comprising:

a display responsive to the controller,

wherein, the display outputs an image comprising at least one of an indication of the operation mode of the terminal and an indication of the transmission/reception notice.

23. The terminal of claim 21, wherein the vibration module generates at least one of:

a first vibration, if a call connection request is transmitted from the terminal;

a second vibration, if a call ready signal is transmitted from the terminal; and

a third vibration, if a call missed signal is transmitted from the terminal.
