  • Patent number: 8131309
    Abstract: A plurality of base transceiver stations and at least one extension device are connected, via an IP network that uses internet protocol. The extension device shares resources of the base transceiver stations by arbitrary changing a connection relationship between the base transceiver stations and the extension devices. When a mobile terminal communicates with a core network, the extension device uses the resources of at least one base transceiver stations according to fluctuation in the amount of traffic.

  • Publication number: 20110092207
    Abstract: In a radio network control device, if TMSI included in a connection request is not stored in a subscriber-information storage unit, IMSI corresponding to the TMSI is acquired from a higher-level device and access control is performed for radio communications between a mobile terminal and a base station.

  • Publication number: 20110002272
    Abstract: A mobile communications network is a communications network that performs both circuit switching and packet switching. A data communications network is a communications network that performs packet switching. A communication apparatus is capable of connecting to the mobile communications network and the data communications network. The communication apparatus includes a communication control unit which obtains access from a mobile station to the mobile communications network, terminates the access whose call type is packet-switched call, and replaces that access with access to the data communications network.

  • Patent number: 7738922
    Abstract: When a terminal enters a cell of a personal-use base station (NBTS) arranged in a certain location area, the terminal receives a location area identifier having a number that is different from an identifier of the location area, and transmits a location updating request with the reception of the location area identifier as a trigger. On receiving the location updating request, a VLR or an NRNC having a registration table, in which the ID of the personal-use base station and the ID of a terminal allowed to use the personal-use base station are registered, judges whether the terminal issued the location updating request is the terminal allowed to use the personal-use base station by referring to the registration table.
