Abstract

A controller device for performing communication control of a mobile terminal belonging to an ad hoc network, includes: a communication environment information obtaining unit configured to obtain communication environment information, which shows a communication environment in the mobile terminal belonging to the ad hoc network, from the mobile terminal; and a proxy control information transmitter unit configured to transmit proxy control information for performing the communication control instead of the controller device, to a predetermined mobile terminal belonging to the ad hoc network, when the obtained communication environment information satisfies a predetermined condition.

Claims

1. A controller device for performing communication control of a mobile terminal belonging to an ad hoc network, comprising:

a communication environment information obtaining unit configured to obtain communication environment information, which shows a communication environment in the mobile terminal belonging to the ad hoc network, from the mobile terminal; and

a proxy control information transmitter unit configured to transmit proxy control information for performing the communication control instead of the controller device, to a predetermined mobile terminal belonging to the ad hoc network, when the obtained communication environment information satisfies a predetermined condition.

2. The controller device according to claim 1, comprising a communication control result receiver unit configured to receive a result of the communication control performed by the predetermined mobile terminal instead of the controller device, when a connection between the mobile terminal belonging to the ad hoc network and the controller device is recovered.

3. The controller device according to claim 1, wherein the communication environment information in the mobile terminal is a state of a radio wave in the mobile terminal.

4. The controller device according to claim 1, wherein the communication control of the mobile terminal is routing control performed through the ad hoc network.

5. A mobile terminal belonging to an ad hoc network, comprising:

a communication environment information transmitter unit configured to transmit to a predetermined controller device communication environment information which shows a communication environment in the mobile terminal;

a proxy control information receiver unit configured to receive proxy control information transmitted by the predetermined controller device, when the communication environment information satisfies predetermined conditions; and

a proxy controller unit configured to perform communication control of a mobile terminal belonging to the ad hoc network instead of the predetermined controller device based on the received proxy control information, when a connection between the mobile terminal and the predetermined controller device is cut at the latest.

6. The mobile terminal according to claim 5, comprising a communication control result transmitter unit configured to transmit to the predetermined controller device a result of the communication control performed instead of the predetermined controller device, when the connection between the mobile terminal and the controller device is recovered.

7. A mobile communication method for performing communication control of a mobile terminal belonging to an ad hoc network, comprising:

obtaining, at a controller device, communication environment information which shows a communication environment in the mobile terminal belonging to the ad hoc network from the mobile terminal;

transmitting, at the controller device, proxy control information for performing the communication control instead of the controller device to a predetermined mobile terminal belonging to the ad hoc network, when the obtained communication environment information satisfies predetermined conditions; and

performing, at the predetermined mobile terminal, the communication control of the mobile terminal belonging to the ad hoc network instead of the predetermined controller device based on the received proxy control information, when a connection between the mobile terminal belonging to the ad hoc network and the predetermined controller device is cut at the latest.
