摘要:
A mobile communication method according to the present invention includes the steps of: establishing a first radio link between the “LTE-AS” and the eNB in response to the “Service Request” received from the “EMM”; transmitting, from the “UMTS-AS” to the “MM/GMM”, the “reconnect request”, after the completion of the switching process from the mobile communication system of the LTE scheme to the mobile communication system of the UMTS scheme, when the “LTE-AS” detects RLF within a first predetermined period after receiving the switching command instructing performance of the switching process; and not transmitting, from the “MM/GMM” to the “UMTS-AS”, the “Service Request” responding to the “reconnect request”, when the mobile station UE has not performed a packet communication in the mobile communication system of the LTE scheme before a start of the switching process.

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.

As a result of ISR being enabled between a portable terminal device and a network which are capable of communicating by using the communication protocols of a plurality of wireless access technologies, the portable terminal device—performs position registration processing between the plurality of wireless access technologies and the portable terminal device each time a fixed period of time elapses, and the portable terminal device is able to move between the plurality of wireless access technologies that have already been registered, without conducting new position registration processing. At this time, if there is a possibility of there being a difference in ISR states (activated or not activated) between the portable terminal device and the network, the portable terminal device ignores any instructions issued by the network for ISR to be enabled in the portable terminal device.

A communication method in a mobile station includes the steps of placing the mobile station in a self mode; and allowing the mobile station to receive a radio wave during the self mode. The communication method may further includes the steps of receiving broadcast information during the self mode; accepting a request for originating a call during the self mode; determining whether the call is an emergency call; and originating the call, when the call is an emergency call.

A mobile station (UE) according to the present invention includes a CSG cell management unit (11) configured to manage one or a plurality of CSG cell IDs; and a control unit (14) configured to eliminate, during a predetermined period included in received broadcast information, a first CSG cell specified by a first CSG cell ID included in the received broadcast information, from target cells of a cell selection, a cell reselection, a PLMN selection or an automatic CSG cell search, when the first CSG cell ID is not managed by the CSG cell management unit.

A radio communication system includes an EPC 100, a 3G network 200 and a mobile station 10 connectable to an external network 300 via any one of the EPC 100 and the 3G network 200. The communication system includes: a handover function unit configured to control a handover from the EPC 100 to the 3G network 200. The number of EPS bearers allowed to be set up with the mobile station 10 and the EPC 100 is larger than the number of PDP contexts allowed to be set up with the mobile station 10 and the 3G network 200. The handover function unit controls the handover in accordance with the number of the EPS beaters already set up with the mobile station 10 and the EPC 100 and the number of the PDP contexts to be newly set up with the mobile station 10 and the 3G network 200.

An object of the present invention is to avoid congestion, by restricting only processing which causes the congestion without affecting processing which essentially should not be restricted. In a mobile communication system according to the present invention, an exchange MSC/SGSN includes: a congestion factor detector configured to detect a congestion occurrence factor in the switching exchange MSC/SGSN, and a restriction indication transmitter configured to transmit, a restriction indication, to a radio network controller, based on the detected congestion occurrence factor, the restriction indication instructing a processing type that should be restricted in the switching exchange MSC/SGSN congestion occurrence factor. The radio network controller RNC is provided with a broadcast information transmitter configured to transmit broadcast information including the received restriction indication to a mobile station UE.
