Abstract

A mobile communication device includes an antenna, a SIM (subscriber identity module) card, and a battery. The antenna receives a control signal from an external device. The SIM card rectifies a charging signal of the control signal received by the antenna. The battery is charged with the rectified charging signal. The control signal may be an RF (radio frequency) control signal.

Claims

1. A mobile communication device comprising:

an antenna receiving a control signal from an external device;

a SIM (subscriber identity module) card rectifying a charging signal of the control signal received by the antenna; and

a battery charged with the rectified charging signal.

2. The mobile communication device of claim 1, wherein the antenna is an RF antenna and the control signal is an RF (radio frequency) signal.

3. The mobile communication device of claim 1, wherein the battery includes a battery cell comprising one of a lithium ion polymer or a nickel hydroxide material.

4. The mobile communication device of claim 1, wherein the control signal includes a data request signal that is used to request an output of data stored in the SIM card.

5. The mobile communication device of claim 1, wherein the antenna is disposed at an edge of the battery.

6. A mobile communication device comprising:

an antenna receiving a control signal from an external device;

a SIM (subscriber identity module) card communicating through the antenna;

a rectifier to rectify a charging signal of the control signal, wherein the control signal is received by the antenna; and

a battery charged with the rectified charging signal.

7. The mobile communication device of claim 6, wherein the antenna is an RF (radio frequency) antenna and the control signal is an RF signal.

8. The mobile communication device of claim 6, wherein the battery includes a battery cell comprising one of a lithium ion polymer or a nickel hydroxide material.

9. The mobile communication device of claim 6, wherein the control signal includes a data request signal that is used to request an output of data stored in the SIM card.

10. The mobile communication device of claim 6, wherein the antenna is disposed at an edge of the battery.

11. The mobile communication device of claim 6, wherein the rectifier is disposed in the battery.

12. A method for charging a battery of a mobile communication device including a SIM card and the battery, the method comprising:

receiving an RF (radio frequency) control signal;

rectifying a charging signal of the received RF control signal; and

charging the battery with the rectified charging signal.

13. The method of claim 12, further comprising using a data request signal of the RF control signal to request an output of data stored in the SIM card.

14. The method of claim 12, wherein the rectifying of the charging signal in the received RF control signal is performed by the SIM card.

15. The method of claim 12, wherein the rectifying of the charging signal in the received RF control signal is performed by a rectifier built into the battery.

16. A communication system comprising:

a mobile communication device antenna to receive a control signal;

a SIM (subscriber identity module) card rectifying a charging signal of the control signal received by the antenna;

a battery charged with the rectified charging signal;

an RF (radio frequency) reader communicating with the mobile communication device antenna; and

a host processing data transmitted and received through the RF reader.

17. The communication system of claim 16, wherein the host receives through the RF reader charging information transmitted from the mobile communication device, and externally displays a charged state of the battery according to the received charging information.

18. The communication system of claim 16, wherein the RF reader comprises a controller to send a data request signal to the SIM card.

19. The communication system of claim 18, wherein the RF reader further comprises a transmitter to modulate the data request signal with the charging signal to generate the control signal.

20. The communication system of claim 16, wherein the control signal is an RF signal.
