摘要:
A terminal device (100) is provided with a C-PLANE processing unit (131) which sets an RRC connection between the terminal device and a radio station (200), and sets an RAB and a PDP context between the terminal device and a network (300), and a U-PLANE processing unit (132) which performs processing for transmitting user data using the PDP context set by the C-PLANE processing unit (131). The C-PLANE processing unit (131) performs local release for releasing the PDP context in the terminal device when the transmission of the user data has failed in a preservation state.

When a browser is started up by a user, a packet call establishment request unit of a cellular phone requests the start of processing for establishing a packet call, and a communication control unit executes a packet all establishment processing. A mobile communication network sends a packet call establishment response message to the cellular phone, then sends packet data. A packet date storage unit of the cellular phone stores the packet data in a memory when packet data is received before the packet call establishment response message. If the packet call establishment response message is received thereafter, the packet data storage unit reads the packet data from the memory, and deletes the packet data from the memory. The packet processing execution unit displays a screen corresponding to the packet data on the display. Thereby, instances when packet data is discarded is decreased.

Provided are a mobile device and location registration method that, even when packet communications are being restricted and the location cannot be registered, the location can be registered rapidly when the access restriction is released. The mobile device comprises a packet timing unit that times a predetermined time; a location registration unit that registers the location to the control server for packet communications; a timing control unit that, if control server for packet communications is under access restriction, controls the timing operations to be temporarily stopped; and a location registration control unit that controls the location registration unit to register the location to the control server for packet communications, and also controls the location registration unit to register the location to the control server for packet communications if the control server for packet communications has released the access restriction and if the timing control unit has stopped the timing operations of the packet timing unit.

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.
