Abstract

A mobile wireless device has a power receiver configured to wirelessly receive power, a first communication unit configured to sequentially perform information transmission, waiting operation, information reception, and internal processing for a certification process, by using the received power, a second communication unit configured to perform wireless communication for data communication during the certification process, by using the received power, and a communication controller configured to control performing the data communication by the second communication unit within a period after the first communication unit starts information transmission for the certification process until the first communication unit completes information reception for the certification process.

Claims

1. A mobile wireless device comprising:

a power receiver configured to wirelessly receive power;

a first communication unit configured to sequentially perform information transmission, waiting operation, information reception, and internal processing for a certification process, by using the received power;

a second communication unit configured to perform wireless communication for data communication during the certification process, by using the received power; and

a communication controller configured to control performing the data communication by the second communication unit within a period after the first communication unit starts information transmission for the certification process until the first communication unit completes information reception for the certification process.

2. The mobile wireless device of claim 1,

wherein the communication controller controls performing the data communication by the second communication unit during a first period after the first communication unit completes transmitting the information for the certification process until the first communication unit starts receiving the information for the certification process.

3. The mobile wireless device of claim 1,

wherein the communication controller controls performing the data communication by the second communication unit during a second period after the first communication unit starts transmitting the information for the certification process until the first communication unit starts receiving the information for the certification process.

4. The mobile wireless device of claim 1,

wherein the communication controller controls performing the data communication by the second communication unit during a third period after the first communication unit completes transmitting the information for the certification process until the first communication unit completes receiving the information for the certification process.

5. The mobile wireless device of claim 1,

wherein the communication controller controls performing the data communication by the second communication unit during a period when the information transmission, waiting operation, and information reception for the certification process are performed.

6. The mobile wireless device of claim 1,

wherein each of the first communication unit and the second communication unit performs proximity wireless communication with a communication partner device placed in proximity thereto.

7. The mobile wireless device of claim 1, further comprising:

a storage configured to store information for the data communication; and

a decryption unit configured to decrypt the information stored in the storage using a key acquired by the first communication unit or the second communication unit, after the certification process is normally completed.

8. The mobile wireless device of claim 1,

wherein communication speed of the second communication unit is faster than that of the first communication unit.

9. The mobile wireless device of claim 8, further comprising:

a power storage unit configured to accumulate the power received by the power receiver,

wherein at least the second communication unit of the first and second communication units is driven by the power supplied from the power storage unit after electric energy accumulated in the power storage unit exceeds a predetermined reference level.

10. A wireless communication method comprising:

wirelessly receiving power;

sequentially performing information transmission, waiting operation, information reception, and internal processing for a certification process, by a first communication unit using the received power;

performing wireless communication for data communication during the certification process, by a second communication unit using the received power; and

controlling performing the data communication by the second communication unit within a period after the first communication unit starts information transmission for the certification process until the first communication unit completes information reception for the certification process.

11. The method of claim 10,

wherein the controlling controls performing the data communication by the second communication unit during a first period after the first communication unit completes transmitting the information for the certification process until the first communication unit starts receiving the information for the certification process.

12. The method of claim 10,

wherein the controlling controls performing the data communication by the second communication unit during a second period after the first communication unit starts transmitting the information for the certification process until the first communication unit starts receiving the information for the certification process.

13. The method of claim 10,

wherein the controlling controls performing the data communication by the second communication unit during a third period after the first communication unit completes transmitting the information for the certification process until the first communication unit completes receiving the information for the certification process.

14. The method of claim 10,

wherein the controlling controls performing the data communication by the second communication unit during a period when the information transmission, waiting operation, and information reception for the certification process are performed.

15. The method of claim 10,

wherein each of the first communication unit and the second communication unit performs proximity wireless communication with a communication partner device placed in proximity thereto.

16. The method of claim 10, further comprising:

storing information for the data communication; and

decrypting the stored information using a key acquired by the first communication unit or the second communication unit, after the certification process is normally completed.

17. The method of claim 10,

wherein communication speed of the second communication unit is faster than that of the first communication unit.

18. The method of claim 17, further comprising:

accumulating the received power,

wherein at least the second communication unit of the first and second communication units is driven by the power supplied from the accumulated power after the accumulated power exceeds a predetermined reference level.
