PROBLEM TO BE SOLVED: To perform handover between a plurality of interfaces in high speed while preventing disconnection of an existing communication path.SOLUTION: A communication device establishes communication using a first communication interface with an opposite device, and then handovers the communication to communication using a second communication interface. The communication device obtains, from the opposite device by use of the first communication interface, at least one of identification information to identify the opposite device and information on a communication path via another device already established by use of the second communication interface at the opposite device, and determines whether connection of a P2P communication path to the opposite device is possible by use of the already established communication path on the basis of at least one of the information on the communication path via the other device already established by use of the second communication interface at the communication device or the opposite device, and the identification information on the opposite device or the communication device. |
