Abstract:
1. A mobile apparatus for performing communications with another apparatus connected to a network by using a first type internet protocol and a second type internet protocol, comprising: a communication portion for transmitting/receiving a packet to/from a network, the packet being compliant with the first type internet protocol or the second type internet protocol; a movement detection processing portion that, when the mobile apparatus is moved from a first network to a second network, executes judgment as to whether the second network is a network in which communications are performed by using at least the first type internet protocol or a network in which communications are performed by using the second type internet protocol; and a packet transmission portion that, when a first packet compliant with the first type internet protocol is to be transmitted to another apparatus connected to a network, creates a second packet by executing encapsulation for encapsulating the first packet with the second type internet protocol, and transmits the second packet via the communication portion, if the movement detection processing portion executes judgment that the second network is a network in which communications are performed by using the second type internet protocol.
