COMMUNICATION DEVICE, COMMUNICATION SYSTEM AND COMMUNICATION METHOD
First Claim
1. A communication device, comprising:
- an electric charger configured to perform a power supply operation with another device located at a shorter distance than a coverage distance of wireless communication by a first communication system, the power supply operation including providing a power supply to, or receiving a power supply from, the another device; and
circuitry configured tostart preparation for wireless communication by a second communication system, which has a larger coverage distance than the coverage distance of wireless communication by the first communication system, when a currently-active power supply operation is interrupted during selection of the first communication system for wireless communication with the another device; and
start wireless communication by the second communication system, in place of the first communication system, based on the preparation for wireless communication by the second communication system.

Abstract
A communication device including an electric charger configured to perform a power supply operation with another device located at a shorter distance than a coverage distance of wireless communication by a first communication system, the power supply operation including providing a power supply to, or receiving a power supply from, the another device. The communication device starts preparation for wireless communication by a second communication system, which has a larger coverage distance than the coverage distance of wireless communication by the first communication system, when a currently-active power supply operation is interrupted during selection of the first communication system for wireless communication with the another device. The communication device then starts wireless communication by the second communication system, in place of the first communication system, based on the preparation for wireless communication by the second communication system.

8. A communication system comprising:
-
a first communication device configured to supply power to a second communication device when a distance between the first and second communication devices is shorter than a maximum of a coverage distance of wireless communication by a first communication system, wherein the first and second communication devices are configured to start preparation for wireless communication by a second communication system that has a larger coverage distance than the maximum of the coverage distance of wireless communication by the first communication system when the power supply from the first communication device to the second communication device is interrupted during wireless communication by the first communication system, and the first and second communication devices are configured to start wireless communication by the second communication system, in place of the first communication system, based on the preparation for wireless communication by the second communication system. - View Dependent Claims (9, 10, 11, 12, 13)

14. A communication method comprising:
-
supplying power from a first communication device having power supply capability to a second communication device when a distance between the first and second communication devices is shorter than a maximum of a coverage distance of wireless communication by a first communication system; starting, by the first and second communication devices, preparation for wireless communication by a second communication system that has a larger coverage distance than the maximum coverage distance of wireless communication by the first communication system, when the power supply is interrupted during wireless communication by the first communication system; and starting, by the first and second communication devices, wireless communication by the second communication system, in place of the first communication system based on the preparation for wireless communication by the second communication system. - View Dependent Claims (15, 16, 17, 18, 19)
