Mobile terminal, wireless communications system and mobile terminal control method
First Claim
1. A mobile terminal configured to constitute an ad hoc network together with a plurality of other terminals, comprising:
- a packet relay unit configured to execute a relay operation of relaying a packet transferred between the other terminals;
a packet transmitter configured to execute a transmission operation of transmitting a packet generated in the mobile terminal to any one of the other terminals;
a power supply manager configured to execute a power supply control operation, which includes a power-off operation;
a coordination controller configured to;
cause the relay operation, the power supply control operation and the transmission operation to be coordinated with each other by selectively controlling whether each of the relay operation, the transmission operation and the power supply control operation is executed;
prioritize the relay operation over the transmission operation and the power-off operation; and
reject a packet transmission request from the packet transmitter during a predetermined time period after power-on, and cause only the relay operation to be executed; and
a determination unit configured to increase the predetermined time period for executing only the relay operation when it is determined that a node density in the ad hoc network is low.

Abstract
A mobile terminal configured to constitute an ad hoc network together with a plurality of other terminals, the mobile terminal includes a packet relay unit configured to execute a relay operation of relaying a packet transferred between the other terminals. A packet transmitter is configured to execute a transmission operation of transmitting a packet generated in the mobile terminal to any one of the other terminals. A power supply manager is configured to execute a power supply control operation. A coordination controller is configured to cause the relay operation and the power supply control operation to be coordinated with each other, and to selectively control whether each of the relay operation, the transmission operation and the power supply control operation is executed.

10. A wireless communication system, comprising:
-
a plurality of mobile terminals configured to constitute an ad hoc network; and a core network configured to control the mobile terminals, wherein each of the mobile terminals comprises; a packet relay unit configured to execute a relay operation of relaying a packet transferred between the other terminals; a packet transmitter configured to execute a transmission operation of transmitting a packet generated in the mobile terminal to any one of the other terminals; and a power supply manager configured to execute a power supply control operation, which includes a power-off operation, wherein the core network is configured to; cause the relay operation, the transmission operation and the power supply control operation to be coordinated with each other by selectively controlling whether each of the relay operation, the transmission operation and the power supply control operation is executed; prioritize the relay operation over the transmission operation and the power-off operation; reject a packet transmission request from the packet transmitter during a predetermined time period after power-on, and cause only the relay operation to be executed; and increase the predetermined time period for executing only the relay operation when it is determined that a node density in the ad hoc network is low.

11. A mobile terminal control method for controlling a mobile terminal configured to constitute an ad hoc network together with a plurality of other terminals, comprising:
-
executing a relay operation of relaying a packet transferred between the other terminals; executing a transmission operation of transmitting a packet generated in the mobile terminal to any one of the other terminals; executing a power supply control operation, which includes a power-off operation; causing the relay operation, the transmission operation and the power supply control operation to be coordinated with each other; controlling whether each of the relay operation, the transmission operation and the power supply control operation is executed, and prioritizing the relay operation over the transmission operation and the power-off operation; rejecting a packet transmission request from the mobile terminal during a predetermined time period after power-on, and causing only the relay operation to be executed; and increasing the predetermined time period for executing only the relay operation when it is determined that a node density in the ad hoc network is low.
