Abstract:
1. A mobile communication terminal adapted to be selectively resident in both a first mobile communication network where a data communication and a voice call can be performed and a second mobile communication network where data communication faster than in the first mobile communication network can be performed, the mobile communication terminal being set to be preferentially resident in the second mobile communication network in a case where the data communication is performed and being adapted to switch the mobile communication network so as to be resident in the first mobile communication network in a case where the voice call is performed, the mobile communication terminal comprising: a receiver that receives network information representing a function of the second mobile communication network from the second mobile communication network; a switching possibility determiner that determines that, based on the network information received by the receiver whether or not the second mobile communication network is a switchable mobile communication network where the mobile communication terminal can switch the mobile communication network so as to be resident in the first mobile communication network in a case of receiving a calling of a voice call during being resident in the second mobile communication network; a first mobile communication network switching controller configured to perform the switching control of the mobile communication network; and a residence prohibiter that causes the mobile communication terminal to remain resident in the first mobile communication network and prohibits the mobile communication terminal from residing in the second mobile communication network when the switching possibility determiner determines that the second mobile communication network is not the switchable communication network.
