Even when the mobile terminal (UE) redirected from the UMTS cell to the LTE cell by the redirecting technology cannot start the communication with the LTE system, the communication with the UMTS system can be started. A mobile terminal (UE) according to the present invention is instructed to be redirected from a UMTS cell to an LTE cell by a radio control apparatus (RNC), in an overlapped area between the UMTS cell in which communication with a UMTS system is available and the LTE cell in which communication with an LTE system is available, by transmitting a connection request signal including an LTE supported identifier for indicating that the LTE system is supported to the radio control apparatus (RNC) of the UMTS system. Moreover, the mobile terminal (UE) includes a connection setting process unit which executes a connection setting process with the radio control apparatus (RNC) while being turned into a state of not supporting the LTE system, when receiving a location registration failure signal for indicating that location registration to the tracking area of the LTE system is ended in failure.
