Abstract:
A mobile communication system comprises: at least one terminal; a source base station to which the terminal is connected before movement of the terminal; a target base station to which the terminal is connected after the movement; a gateway device that connects the source base station and the target base station to a core network; and a core network node provided in the core network, wherein: the gateway device determines by itself, or makes query to the core network node to determine whether or not to preferentially treat the terminal by the target base station when the terminal moves from the source base station to the target base station; and the gateway device notifies to the target base station preferential information indicative of whether or not to preferentially treat the terminal by the target base station.
Abstract:
A communication system is described in which mobile telephones that are members of closed subscriber groups associated with home base stations are able to roam between neighbouring home node base stations in a manner that reduces load on the core network.
Abstract:
A mobile communication system includes a control device and a base station device. Data communication between the control device and the base station device is conducted using a fixed-length data size and a variable-length data size. The control device transmits information indicating whether a data size of the data communication has a fixed length or a variable length. The base station device receives the information from the control device.
Abstract:
At the time of registration of a base station, the base station reports to a gateway device list information regarding core networks that are to be connected. At the time of call origination from a user terminal, the base station reports to the gateway device, by means of a message of protocol for termination between a base station and a gateway, network identification information that indicates core networks that are to be connected to the user terminal The gateway device transfers a control message from the user terminal to the core networks indicated by the network identification information that was reported. At the time of call connection to the user terminal, the gateway device selects the base station to which paging from the core network is to be transmitted on the basis of the list information reported from the base station at the time of registration.

Abstract:
A mobile communication system according to the present invention capable of efficiently reducing power consumption of a radio base station apparatus includes a radio base station apparatus 1 for performing communication with a mobile terminal 4, a location information management apparatus 3 for acquiring location information of the mobile terminal 4, and a processing apparatus 2 for changing an operation state of the radio base station apparatus 1 by changing at least one of intensity, type, and cycle of radio waves emitted from the radio base station apparatus 1 or by setting the radio base station apparatus 1 in such a way that the radio base station apparatus 1 does not emit radio waves based on the location information of the mobile terminal 4 acquired by the location information management apparatus 3.
Abstract:
A mobile communication system includes a mobile station, a base station that communicates wirelessly with the mobile station, a gateway apparatus that connects the base station to a core network, and a core network apparatus that is arranged in the core network. The base station includes a control unit that includes, in a message, information indicating that the mobile station has originated a call as an emergency call, and a transmission unit that transmits the message to the core network apparatus. In addition, the core network apparatus includes a reception unit that receives the message that was transmitted from the base station.

Abstract:
To provide a base station which makes it possible to apply HSDPA to radio bearers in the RLC-TM, such as circuit switched calls, as well and which can use the radio capacity to the full. A call controller 23 terminates control signals, such as NBAP and ALCAP, and exercises control on a scheduler 24, a ciphering function unit 21 and a radio modulator 22. The scheduler 24 conducts scheduling of time division in downlink user data transfer. The ciphering controller 21 executes ciphering on data scheduled in the scheduler 24 on the basis of ciphering control information supplied from the call controller 23, and transmits resultant data to the radio modulator 22. The radio modulator 22 conducts radio modulation, and transmits data to the mobile station.
