Abstract

The present invention relates to an apparatus for integrating voice and data communications. The apparatus respectively electrically couples to a terminal device and a base station. The apparatus includes a wireless local area network module, a mobile communication network module, and an audio gateway. The wireless local area network module and the mobile communication network module transmit the voice signal and/or data signal to the terminal device and the base station.

Claims

1. An apparatus for integrating voice and data communications in a personal digital assistant (PDA), said apparatus respectively electrically coupling to a terminal device and a base station, said PDA including an interface, said apparatus comprising:

a wireless local area network module for transmitting a first voice signal and/or a first data signal to said terminal device and transmitting said first voice signal and/or said first data signal to said interface of said PDA via a bus;

a mobile communication network module for transmitting a second voice signal and/or a second data signal to said base station; and

an audio gateway for controlling transmission of said first voice signal and/or said second voice signal among said wireless local area network module, said mobile communication network module, and said interface.

2. The apparatus of claim 1 further comprising a transceiver for transmitting said first data signal and/or said second data signal to said interface of said PDA.

3. The apparatus of claim 2, wherein said transceiver comprises a universal asynchronous receiver/transmitter.

4. The apparatus of claim 2 further comprising a central control unit for processing said first data signal or said second data signal between said mobile communication network module and said transceiver.

5. The apparatus of claim 4, wherein said central control unit comprises a microcontroller.

6. The apparatus of claim 1, wherein said wireless local area network module comprises a bluetooth module.

7. The apparatus of claim 1, wherein said terminal device comprises a bluetooth earphone.

8. The apparatus of claim 1, wherein said terminal device comprises a bluetooth printer.

9. The apparatus of claim 1, wherein said terminal device comprises a personal computer with a bluetooth module.

10. The apparatus of claim 1, wherein said bus comprises a universal serial bus (USB).

11. The apparatus of claim 1, wherein said bus comprises a universal asynchronous receiver/transmitter (UART).

12. The apparatus of claim 1, wherein said bus comprises a PCMCIA (personal computer memory card international association) bus.

13. The apparatus of claim 1, wherein said mobile communication network module comprises a GSM (global system for mobile communication) module.

14. The apparatus of claim 1, wherein said mobile communication network module comprises a GPRS (general packet radio service) module.

15. The apparatus of claim 1, wherein said mobile communication network module comprises a CDMA (code-division multiple access) module.

16. The apparatus of claim 1 further comprising a network control unit interface for receiving a carrier signal.

17. The apparatus of claim 16, wherein said carrier signal is transmitted to said wireless local area network module via said audio gateway and to said terminal device via said wireless local area network module.

18. The apparatus of claim 17, wherein said wireless local area network module comprises a bluetooth module.

19. The apparatus of claim 17, wherein said terminal device comprises a bluetooth earphone.
