  • Publication number: 20130072199
    Abstract: In order to realize hand over between an existing communication network and an FAP in a communication system with a different communication procedure, without requiring improvement of an existing communication system, a gateway device and the Femto Access Point configure virtual RNC means which is recognized as an RNC by an RNC when communication with the RNC is performed, and if the hand over is performed between a BTS and the Femto Access Point, the virtual RNC means transmits and receives a message containing hand over information for call control to and from the RNC.

  • Publication number: 20130065606
    Abstract: Provided is a broadcast control apparatus that realizes broadcasting to a predetermined distribution area, as in an existing public mobile communication network in a communication system using a femto cell base station. The broadcast control apparatus includes a database, in which location information of the femto cell base station existing in a predetermined distribution area section is associated with the distribution area section. The broadcast control apparatus also includes update means for updating the association in the database based on the location information of the femto cell base station received by reception means.

  • Publication number: 20120021736
    Abstract: The femto cell base station is a femto cell base station that connects a UE (User Equipment) to a core network side and includes storing means and control means. The storing means retains subscriber information of the UE visiting an area under control of the femto cell base station. The control means deletes the subscriber information of the UE, that is removed from the control of the femto cell base station, from the storing means.

  • Publication number: 20110269427
    Abstract: A Femtocell base station has a determination means and a transmission means. The determination means, upon receiving a location update request message from UE (User Equipment), determines whether a first message that prompts the UE to again attempt a location update should be transmitted to the UE, whether a second message that prompts the UE to divert to another network should be transmitted to the UE, or whether a third message that notifies the UE that the location update request is accepted should be transmitted to the UE. The transmission means transmits to the UE either the first message, or the second message, or the third message in accordance with the determination of the determination means.

  • Publication number: 20110269483
    Abstract: A Femto Access Point includes determination means for determining whether or not called side user equipment is accommodated in the Femto Access Point; and communication control means for, if the determination means has determined that the called side user equipment is accommodated in the Femto Access Point, sending out a Ring Back Tone to calling side user equipment.

  • Publication number: 20060113189
    Abstract: An objective of the present invention is to provide electrophoretic separation methods and devices that enable the various features of a substrate surface that comes in contact with an electrophoresis medium to be controlled. The present invention provides methods for electrophoresing substances, which comprises the steps of: (a) adding a substance to be analyzed to an electrophoresis medium retained in a substrate, whose surface that has come in contact with the electrophoresis medium has been coated with a polymer membrane; and (b) adding electrophoretic pressure to the electrophoresis medium. For example, the use of a plasma-polymerized membrane allows the formation of a membrane with homogeneous quality and thickness on the surface of an arbitrary shape. In addition, desired characteristics can be conferred on the surface through selection of monomeric substances. Protein adsorption onto micro-chips can be effectively prevented as well.

  • Publication number: 20030113231
    Abstract: The present invention provides a differential SPR sensor that is capable of independently determining resonance wavelenghts without determining a baseline. A differential SPR sensor is formed with a surface immobilized with a recognition component and a surface not immobilized with the component on a metal film. The sensor comprises a plurality of dielectric films of different film thicknesses formed on the metal film, wherein one of said dielectric films is taken to be a reference surface and at least the other one dielectric film is taken to be a working surface immobilized with the recognition component. Preferably, the sensor is a probe-type SPR sensor, and a working surface and a reference surface are formed on a metal film providing a sensor surface of the probe.

  • Patent number: 6500679
    Abstract: The present invention aims to achieve a chip having a construction in which each film of metal, dielectric, and fluorescent material is stacked on a glass substrate 1. Such a construction can enhance the intensity of fluorescence emitted from a fluorescent material owing to the interaction between the fluorescent material and the light propagation mode in that construction.
