PROBLEM TO BE SOLVED: To provide a communication terminal device capable of performing data synchronization processing with a communication opposite party without going through a server on a communication network and without increasing a communication load on the communication network.SOLUTION: A communication terminal device comprises: a first communication unit for communicating via a communication network; a second communication unit for communicating with a device situated in the vicinity of the communication terminal device by a short-range wireless communication scheme; and a control unit for performing control so as to preferentially establish a second communication path with a communication opposite party by the short-range wireless communication scheme than a first communication path with the communication opposite party via the communication network as a communication path for two-way communication used for data synchronization processing with the communication opposite party.SELECTED DRAWING: Figure 10 |
