Abstract

A communication device includes a first module, a communication portion communicating with a second module, a memory, and a processor that executes instructions stored in the memory. The instructions cause the processor to perform: executing a processing of changing a first radio communication to a non-restrictive state when a first signal is received from the second module in a state that the first radio communication is in a restrictive state; and executing a first processing of transmitting a second signal for changing a second radio communication to the non-restrictive state to the second module and a second processing of changing the first radio communication to the restrictive state when the priority signal using the first channel is detected in a state that the first radio communication is in the non-restrictive state.

First claim

What is claimed is:

1. A communication device comprising:
a first module configured to perform a first radio communication using a first channel and to detect a priority signal using the first channel, the priority signal using the first channel being a signal that when detected, causes the first radio communication being performed using the first channel to be halted;
a communication portion configured to communicate with a second module that is configured to perform a second radio communication using a second channel different from the first channel and to detect a priority signal using the second channel, the priority signal using the second channel being a signal that when detected, causes the second radio communication being performed using the second channel to be halted;
a memory that stores instructions; and
a processor that executes the instructions,
wherein the instructions, when executed by the processor, cause the processor to:
execute a processing of changing the first radio communication to a non-restrictive state when a first signal is received from the second module in a state that the first radio communication is in a restrictive state; and
execute a first processing of transmitting a second signal for changing the second radio communication to the non-restrictive state to the second module and a second processing of changing the first radio communication to the restrictive state when the priority signal using the first channel is detected in a state that the first radio communication is in the non-restrictive state.

2. The communication device according to claim 1 , wherein the instructions, when executed by the processor, cause the processor to:
execute a third processing of changing the channel of the first module to a predetermined channel when the priority signal using the first channel is detected before a predetermined time elapses from the detection of the priority signal using the second channel in a state that the second radio communication is in the restrictive state; and
execute the first processing and the second processing after executing the third processing.

3. The communication device according to claim 2 , wherein the predetermined time is one minute.

4. The communication device according to claim 1 , wherein the instructions, when executed by the processor, cause the processor to:
execute the first processing when the number of communication terminals using the first radio communication exceeds a predetermined number in a state that the first radio communication is in the non-restrictive state and the second radio communication is in the restrictive state.

5. The communication device according to claim 1 , wherein the instructions, when executed by the processor, cause the processor to:
execute a fourth processing of changing the channel being set to the first module from the first channel to a third channel different from the second channel.

6. The communication device according to claim 5 , further comprising:
a register configured to register the channel where the detected priority signal is used into a memory,
wherein the instructions, when executed by the processor, cause the processor to:
determine the third channel in response to the channel registered in the memory.

7. A communication system comprising:
a first module configured to perform a first radio communication using a first channel and to detect a priority signal using the first channel, the priority signal using the first channel being a signal that when detected, causes the first radio communication being performed using the first channel to be halted;
a second module configured to perform a second radio communication using a second channel different from the first channel and to detect a priority signal using the second channel, the priority signal using the second channel being a signal that when detected, causes the second radio communication being performed using the second channel to be halted;
a memory that stores instructions; and
a processor that executes the instructions,
wherein the instructions, when executed by the processor, cause the processor to:
execute a first processing of changing the second radio communication to a non-restrictive state and a second processing of changing the first radio communication to a restrictive state when the priority signal using the first channel is detected in a state that the first radio communication is in the non-restrictive state and the second radio communication is in the restrictive state.

8. The communication system according to claim 7 , wherein the instructions, when executed by the processor, cause the processor to:
execute a third processing of changing the channel of the first module to a predetermined channel when the priority signal using the first channel is detected before a predetermined time elapses from the detection of the priority signal using the second channel in a state that the second radio communication is in the restrictive state; and
execute the first processing and the second processing after executing the third processing.

9. The communication system according to claim 8 , wherein the predetermined time is one minute.

10. The communication system according to claim 1 , further comprising:
a housing that accommodates the first module and the second module.

11. The communication system according to claim 1 , wherein the instructions, when executed by the processor, cause the processor to:
execute the first processing when the number of communication terminals using the first radio communication exceeds a predetermined number in a state that the first radio communication is in the non-restrictive state and the second radio communication is in the restrictive state.

12. The communication system according to claim 7 , wherein the instructions, when executed by the processor, cause the processor to:
execute a fourth processing of changing the channel being set to the first module from the first channel to a third channel different from the second channel.

13. The communication system according to claim 12 , further comprising:
a register configured to register the channel where the detected priority signal is used into a memory,
wherein the instructions, when executed by the processor, cause the processor to:
determine the third channel in response to the channel registered in the memory.

14. A control device for controlling a first module that performs a first radio communication using a first channel and detects a priority signal using the first channel, the priority signal using the first channel being a signal that when detected, causes the first radio communication being performed using the first channel to be halted, and a second module that performs a second radio communication using a second channel different from the first channel and detects a priority signal using the second channel, the priority signal using the second channel being a signal that when detected, causes the second radio communication being performed using the second channel to be halted, the control device comprising:
a memory that stores instructions; and
a processor that executes the instructions,
wherein the instructions, when executed by the processor, cause the processor to:
execute a first processing of changing the second radio communication to a non-restrictive state and a second processing of changing the first radio communication to a restrictive state when the priority signal using the first channel is detected in a state that the first radio communication is in the non-restrictive state and the second radio communication is in the rest
