Abstract

A mobile communication terminal includes a first transceiver that transmits and receives signals, an RFID transceiver that transmits and receives signals, and a controller that stops the first transceiver while it is performing signal communication, and activates the RFID transceiver.

Claims

1. A communication terminal, comprising:

a first transceiver that selectively transmits and receives signals;

an RFID transceiver that selectively transmits and receives signals; and

a controller that halts an operation of the first transceiver while said communication terminal is performing a signal communication, and activates the RFID transceiver.

2. The mobile communication terminal of claim 1, further comprising a duplexer that alternately connects an antenna to the first transceiver and the RFID transceiver.

3. The mobile communication terminal of claim 1, wherein the signal communication performed by the first transceiver is a voice call communicated using CDMA.

4. The mobile communication terminal of claim 1, wherein the controller controls whether an antenna is connected to the first transceiver or the RFID transceiver.

5. The mobile communication terminal of claim 1, wherein the controller connects the first transceiver to an antenna when the mobile communication terminal is in an idle mode, and connects the RFID transceiver to the antenna when the mobile communication terminal is in a sleep mode.

6. The mobile communication terminal of claim 1, wherein the controller connects the RFID module to an antenna for a predetermined time period while the mobile communication terminal is in a calling state.

7. The mobile communication terminal of claim 6, wherein the controller periodically connects the RFID module to the antenna according to a slot cycle of the mobile communication terminal.

8. The mobile communication terminal of claim 6, wherein the controller connects the RFID module to the antenna for a predetermined time period during a sleep mode.

9. The mobile communication terminal of claim 8, wherein the mobile communication terminal does not communicate with a base station during the sleep mode.

10. The mobile communication terminal of claim 1, wherein the RFID transceiver communicates with a transponder.

11. A method for sharing an antenna of a mobile communication terminal, comprising:

determining whether the mobile communication terminal is in a calling state;

controlling a connection of an antenna between a first transceiver and an RFID transceiver in response to the determination of whether the mobile communication terminal is in the calling state; and

activating the RFID transceiver.

12. The method of claim 11, wherein controlling the connection of the antenna comprises connecting the antenna to the first transceiver when the mobile communication terminal is in an idle mode, and connecting the antenna to the RFID module when the mobile communication terminal is in a sleep mode.

13. The method of claim 12, wherein the RFID transceiver is connected to the antenna for a predetermined time period during the sleep mode.

14. The method of claim 11, wherein controlling the connection of the antenna comprises periodically stopping a communication by the first transceiver when the mobile communication terminal is in a calling state, and connecting the RFID transceiver to the antenna.

15. The method of claim 14, wherein the RFID transceiver is periodically connected to the antenna according to a slot cycle of the mobile communication terminal.

16. The method of claim 11, wherein the RFID communicates with a transponder.

17. A method for sharing an antenna of a mobile communication terminal, comprising:

temporarily stopping call traffic communication during a calling state of the mobile communication terminal;

activating an RFID transceiver to perform RFID communication while the call traffic communication is temporarily stopped; and

re-starting the call traffic communication when the RFID communication is completed.

18. The method of claim 17, wherein the RFID transceiver is activated according to a slot cycle of the mobile communication terminal.

19. A computer-readable medium which stores a program for sharing an antenna of a mobile communication terminal, the program comprising:

a determination code segment that determines whether the mobile communication terminal is in a calling state; and

a control code segment that controls a connection of an antenna between a first transceiver and an RFID transceiver according to whether the mobile communication terminal is in the calling state.

20. A computer-readable medium which stores a program for sharing an antenna of a mobile communication terminal, the program comprising:

a stopping code segment that temporarily stops call traffic communication during a calling state of the mobile communication terminal;

an activating code segment that activates an RFID transceiver to perform RFID communication while the call traffic communication is temporarily stopped; and

a re-starting code segment that re-starts the call traffic communication when the RFID communication is completed.
