Patent number 8768333 is assigned to
The following quote was obtained by the news editors from the background information supplied by the inventors: "Recently, facilities of a subminiature base station (femtocell base station) according to a femtocell system are developed. Further, it is technically possible to establish a base station that can be connected to the Ethernet line or a broadband line. An amendment to relevant bills is prepared in
"The following technique is disclosed in Japanese Laid-open Patent Publication No. 2006-217443. In the case that a call request was received from a mobile station, a location area of a transmission destination is specified by a general phone number of the transmission destination, a distance segment from the mobile station of a transmitting source to the mobile station of the transmission destination is obtained from charging information for calculating call charges, a call charge unit in a communication system of each phone number of the transmission destination is calculated on the basis of the distance segment, the current time, and subscription condition information and the lowest call charge system is selected from among the call charge unit.
"The following technique is disclosed in Japanese Laid-open Patent Publication No. 9-18963. At the outgoing call from a PHS terminal, subscriber identification information to be sent from the PHS station is transmitted to a PHS management center with a D-channel packet on an I' line and is then authenticated at a PHS base station. And, after obtaining the authentication result, the call from the PHS terminal is transmitted via an analog line or the I' line at the PHS base station, thereby selecting a communication carrier with the lowest costs.
"Since it is assumed that a communication service is provided on the unit basis of a communication carrier over a system having the conventional femtocell base station, a user of the femtocell base station cannot select a connection to a core network of an arbitrary communication carrier from the femtocell base station.
"Therefore, when differing communication carriers subscribed by the user of the femtocell base station in each general household or office, the femtocell base station can be used only a user having a terminal of a communication carrier dependent on the set femtocell base station. When the user changes the communication carrier, the user cannot apply the femtocell base station of the communication carrier before the change thereof."
In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventors' summary information for this patent: "According to an aspect of an embodiment, there is provided a communication apparatus for communicating by radio with mobile stations located in a radio communication area of the communication apparatus and for connecting to a network of a communication carrier, the communication apparatus including obtainment means for obtaining information on a selection equipment for selecting a control equipment on a basis of data stored in a detachable data storage device in case of the data storage device being connected to the communication apparatus, reception means for receiving information on the control equipment selected from a plurality of control equipments by the selection equipment accessed from the communication apparatus on a basis of the obtained information on the selection equipment, from the selection equipment, and connection means for performing communication by radio to the mobile station with the selected control equipment on a basis of the received information on the control equipment.
"The object and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the claims.
"It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not restrictive of the invention, as claimed."
