Mobile terminal, control device and mobile communication method
First Claim
1. A mobile terminal comprising:
- a first wireless interface configured to perform communication through a public mobile communication network;
a second wireless interface configured to perform direct communication with another mobile terminal;
an update information transmitter unit configured to transmit update information including identification information and communication state information of the mobile terminal, to a control device in the public mobile communication network through the first wireless interface at a predetermined timing;
a route maintaining unit configured to receive a packet transfer route generated by the control device of the public mobile communication network based on the update information through the first wireless interface, and to maintain the packet transfer route; and
a packet transmitter unit configured to transmit a packet to another mobile terminal through the second wireless interface based on the packet transfer route, whereinthe communication state information includes at least one of an amount of battery remaining in the mobile terminal, a moving speed of the mobile terminal, and a moving frequency of the mobile terminal, andthe update information transmitter unit is configured to decrease the transmission frequency of the update information in any one of cases where the amount of battery remaining in the mobile terminal is equal to or less than a predetermined amount, where the moving speed of the mobile terminal is equal to or faster than a predetermined speed, and where the moving frequency of the mobile terminal is equal to or more than a predetermined frequency.
