摘要:
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.

In a mobile communication method, when a mobile station UE has moved from an area inside UTRAN to an area inside E-UTRAN, a connection process with “Default APN” is executed if no connection with the “Default APN” is established even if it is determined that no position registration process need to be executed for the E-UTRAN.

A mobile communication method according to the present invention includes the steps of: transmitting, to a mobile switching center MME/SGSN, a NAS connection establishment request for the specific communication, while an AS connection, is established between the mobile station UE and a radio access network apparatus eNB/RNC; determining, at the mobile switching center MME/SGSN, to restrict establishment of the NAS connection for the specific communication, when the NAS connection establishment request signal is received and when a predetermined condition is satisfied; and restricting, at the mobile station UE, transmission of a first connection establishment request signal and transmission of the NAS connection establishment request signal, after reception of a rejection signal including a restriction time period for restricting establishment of the NAS connection for the specific communication until expiry of the restriction time period.

A communication method according to the present invention includes: transmitting, at a radio base station device (b), broadcast information for notifying a first area and a second area; transmitting, from a first mobile terminal to a radio control device (c), a first location registration request signal for the first area included in the broadcast information, when the first area is not identical to a first area stored as a current location registration area; and transmitting, from a second mobile terminal to the radio control device (c), a second location registration request signal for the second area included in the broadcast information, when the second area is not included in a second area group stored as a current location registration area.

A packet communication method of the present invention includes a step of: receiving, at a mobile station (UE), restriction information for accepting an incoming call and restricting an outgoing call; establishing, at the mobile station (UE), a control path with a packet exchange (SGSN) in response to incoming of paging for the mobile station (UE); sending, the packet exchange (SGSN), a message instructing to establish the data path via the control path; and establishing, at the mobile station (UE), the data path by calling to the packet exchange (SGSN), when the mobile station (UE) receives the message after the mobile station (UE) has received the restriction information.

An object of the present invention is to allow a cellular phone to establish a video-phone call even when there is an incoming video-phone call during the packet communications. The cellular phone system comprises a cellular phone and the Mobile Multimedia Switching Center (MMS). The MMS comprises a call type judgment section that judges, when a call request is made to the cellular phone, whether the call request is for a video-phone call; a communication status judgment section that judges whether the cellular phone is performing packet communications; and an adding section that adds call information to the effect that the call request is for a video-phone call to an incoming call signal in cases where the call request is for a video-phone call and packet communications are being performed. The cellular phone comprises reporting means (DCF or the like) for judging whether call information has been added to the incoming call signal when the cellular phone is performing packet communications and for reporting that there has been an incoming video-phone call and establishment means (MTF and TAF (AV) and so forth) for establishing a video-phone call by disconnecting the packet communications.

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.
