20100120461 | ACCESS CONTROL METHOD FOR CERTAIN USER TARGETED BASE STATION, BASE STATION APPARATUS AND MOBILE COMMUNICATION MANAGEMENT APPARATUS - In a mobile communication system including Home eNBs, information on mobile stations permitted to access each Home eNB can be easily registered, and the permitted mobile stations can be connected to the Home eNB substantially at the same time of the registration of the access permission. In order to control access to a certain user targeted base station, the information on mobile stations permitted to access the certain user targeted base station is supplied to the certain user targeted base station. Then, the information on the access permitted mobile stations is transmitted to a mobile communication management apparatus on a network. The access permitted mobile station registration is stored in the mobile communication management apparatus in association with the certain user targeted base station. When the access permitted mobile station has entered a location registration area covering the certain user targeted base station or exists in the location registration area, the mobile communication management apparatus transmits connection information for the certain user targeted base station to the mobile station. | 05-13-2010 |

The mobile communications system includes a unit which causes a mobile station apparatus residing within a communication area of an arbitrary base station apparatus to measure a propagation state of a wireless signal from a surrounding base station apparatus and which collects the measurement results; and a unit which obtains location information of the mobile station apparatus. | 05-27-2010 |
20100135174 | MOBILE COMMUNICATION SYSTEM, BASE STATION CONTROLLER, BASE STATION, MOBILE STATION, AND BASE STATION RADIO PARAMETER CONTROL METHOD - A mobile communication system includes a condition reporting unit provided in a base station controller and configured to report to a mobile station via the target base station or another base station measurement and report conditions for determining whether to measure and report a reception quality level of a radio signal transmitted from the target base station; a measurement reporting unit provided in the mobile station and configured to measure the reception quality level of the radio signal if the measurement condition is satisfied and to report the measured reception quality level to the base station controller via the target base station or the other base station if the report condition is satisfied; and a radio parameter control unit provided in the base station controller and configured to control a radio parameter of the target base station or the other base station based on the reported reception quality level. | 06-03-2010 |
20100136985 | MOBILE STATION, BASE STATION, AND AREA SHAPING METHOD PERFORMED BY SPECIFIED BASE STATION - A disclosed base station includes a communication unit configured to receive from a mobile station a first report signal including base station specification information specifying a base station, reception quality information indicating reception quality of a signal received from the specified base station, and change request information requesting to change communication quality between the mobile station and the specified base station; and an automatic area control unit configured to determine whether the base station is specified by the base station specification information, to obtain location information indicating the location of the mobile station if the base station is specified by the base station specification information, and to change at least one base station parameter based on the reception quality information and the location information to change the reception quality at the location of the mobile station. | 06-03-2010 |
20100151852 | MOBILE COMMUNICATION SYSTEM, BASE STATION CONTROLLER, BASE STATION, AND BASE STATION STATE CONTROL METHOD - A mobile communication system includes an association requesting unit provided in a base station and configured to request a base station controller, which is an upper node, to associate the base station with a tracking area; and a state control unit provided in the base station controller and configured to monitor entry or appearance and exit or disappearance of mobile stations in and from the tracking area associated with the base station, to cause the base station to transition to a serving state if at least one of the mobile stations enters or appears in the tracking area, and to cause the base station to transition to a radio-unit-inactive state if all of the mobile stations exit or disappear from the tracking area. | 06-17-2010 |
20100151864 | CONNECTION CONTROL METHOD FOR MOBILE COMMUNICATION, MOBILE COMMUNICATION MANAGEMENT APPARATUS AND MOBILE STATION APPARATUS - In a mobile communication system including a certain user targeted base station (Home eNB), fast cell search and handover are achieved without unnecessary signaling and without increasing interference with other cells. In the mobile communication system, when it is detected that a mobile station permitted to access the certain user targeted base station has entered or exists within a location registration area associated with the certain user targeted base station, connection information including at least frequency information being presently used by the certain user targeted base station and ID information for the certain user targeted base station is transmitted to the mobile station in a dedicated manner. The mobile station performs cell search based on the transmitted connection information. In a preferred embodiment, the mobile station receives adjacent cell frequency information broadcast from a resident public targeted base station and performs the cell search based on the frequency information in the transmitted connection information as well as the adjacent cell frequency information. | 06-17-2010 |
20110051609 | BASE STATION APPARATUS, MOBILE STATION APPARATUS, AND MOBILE STATION CONTROL METHOD IN MOBILE COMMUNICATION SYSTEM - A disclosed base station apparatus in a mobile communication system includes a receiving unit receiving a random access channel transmitted from a mobile station apparatus, an acquisition unit acquiring random access channel quality based on a measurement of the received random access channel or a report from the mobile station apparatus, a calculation unit calculating random access channel parameters based on the acquired random access channel quality, and a broadcast unit broadcasting the calculated random access channel parameters to all the mobile stations within a coverage area of the base station. | 03-03-2011 |
20110130143 | MOBILE COMMUNICATIONS SYSTEM, GENERAL BASE STATION APPARATUS, BASE STATION APPARATUS, AND BASE STATION STATUS CONTROL METHOD - A mobile communications system is disclosed.
