MOBILE TERMINAL, CONTROLLER AND MOBILE COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To suppress a traffic amount required to calculate a packet transfer route in communication that uses direct communication between mobile terminals to each other.

SOLUTION: This mobile communication method comprises: a process in which a mobile terminal MT#A transmits, to a controller 30 in a public communication network, update information including its own identification information and communication state information through a first radio interface 11 at prescribed timing; a process in which the controller 30 calculates an optimum packet transfer route among a plurality of packet transfer routes from the mobile terminal MT#A to a destination terminal MT#B on the basis of the communication state information included in the received update information; and a process in which the controller 30 notifies the mobile terminal MT#A of the calculated packet transfer route; and a process in which the mobile terminal MT#A transmits a packet to another mobile terminal MT#1 through a second radio interface 12 on the basis of the packet transfer route.
