MOBILE TERMINAL AND MOBILE COMMUNICATION METHOD
First Claim
1. A mobile terminal instructed to be redirected from a first cell to a second cell by a first wireless access apparatus, in an overlapped area between the first cell in which communication with a first system is available and the second cell in which communication with a second system is available, by transmitting a connection request signal including a supported identifier for indicating that the second system is supported to the first wireless access apparatus of the first system, the mobile terminal comprising:
- a connection setting process unit configured to execute a connection setting process with the first wireless access apparatus while being turned into a state of not supporting the second system, when receiving a location registration failure signal for indicating that location registration to the second location registered area of the second system is ended in failure.

Abstract
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.
