Abstract

A communication system constructs a communication network using a hopping pattern designated in a router advertisement between a wireless communication device that transmits the router advertisement designating the hopping pattern of channel hopping and an opposite party communication device that receives the router advertisement. The wireless communication device comprises a receiver configured to receive a router advertisement transmitted from another wireless communication device, a generator configured to generate the hopping pattern that does not use the same channel at the same time with respect to a hopping pattern that is designated by the router advertisement received by the receiver, and a transmitter configured to transmit the router advertisement that designates the hopping pattern generated by the generator.

Claims

1. A communication system which constructs a communication network using a hopping pattern designated in a router advertisement between a wireless communication device that transmits the router advertisement designating the hopping pattern of channel hopping and an opposite party communication device that receives the router advertisement,

wherein the wireless communication device comprises:

a receiver configured to receive a router advertisement transmitted from another wireless communication device;

a generator configured to generate the hopping pattern that does not use the same channel at the same time with respect to a hopping pattern that is designated by the router advertisement received by the receiver; and

a transmitter configured to transmit the router advertisement that designates the hopping pattern generated by the generator.

2. The communication system according to claim 1, wherein the generator is configured to generate the hopping pattern having the same period as the hopping pattern that is designated by the router advertisement received by the receiver.

3. The communication system according to claim 1, wherein the generator is configured to generate the hopping pattern having a different temporal offset and the same repeating pattern as the hopping pattern that is designated by the router advertisement received by the receiver.

4. The communication system according to claim 1, wherein the generator is configured to generate the hopping pattern which uses only time slots that are not used by the hopping pattern designated by the router advertisement received by the receiver.

5. The communication system according to claim 1, wherein the generator is configured to generate a hopping pattern according to an instruction through a user interface, and

the transmitter is configured to transmit the router advertisement that designates the hopping pattern generated according to the instruction.

6. The communication system according to claim 1, wherein the wireless communication device is a handheld device that uses provisioning.

7. A communication method, which constructs a communication network using a hopping pattern designated in a router advertisement between a wireless communication device that transmits the router advertisement designating the hopping pattern of channel hopping and an opposite party communication device that receives the router advertisement, comprising:

receiving, by a wireless communication device, a router advertisement transmitted from another wireless communication device;

generating the hopping pattern that does not use the same channel at the same time with respect to a hopping pattern that is designated by the router advertisement received form the other wireless communication device; and

transmitting, by the wireless communication device, the router advertisement that designates the generated hopping pattern.

8. The communication method according to claim 7, wherein the generated hopping pattern is a hopping pattern having the same period as the hopping pattern that is designated by the router advertisement received from the other wireless communication device.

9. The communication method according to claim 7, wherein the generated hopping pattern is a hopping pattern having a different temporal offset and the same repeating pattern as the hopping pattern that is designated by the router advertisement received from the other wireless communication device.

10. The communication method according to claim 7, wherein the generated hopping pattern is a hopping pattern which uses only time slots that are not used by the hopping pattern designated by the router advertisement received from the other wireless communication device.

11. The communication method according to claim 7, further comprising:

generating the hopping pattern according to an instruction through a user interface and transmitting the router advertisement that designates the hopping pattern generated according to the instruction.
