  • Patent number: 8078173
    Abstract: A data transfer system includes a data conversion storage server (3) that generates data (MD1) having a size smaller than a size of data (MD0) received from a delivery server (5) by performing a specific process on the data (MD0). A base station control unit (2) is provided with a data transferring portion that transfers one of the data (MD0 and MD1) selectively to a mobile phone terminal (1), and an approaching mobile communication equipment sensing portion that senses a mobile phone terminal (1) that is receiving the data (MD0) and is approaching an HSDPA supporting wireless base station (4). Then, the data transferring portion stops sending the data (MD0) to the mobile phone terminal (1) sensed by the approaching mobile communication equipment sensing portion, and instead it starts transferring data (MD2) related to a part of the first data to be transferred.

  • Patent number: 7881203
    Abstract: A terminal regulation management device capable of flexibly managing terminals in times of unexpected incident, to ensure communications of users whose daily life zone overlaps with the site of the incident and of users whose daily life zone is outside the site. A priority information memory stores, with respect to each base station, priority information indicating priority levels as to subscribers' incoming/outgoing calls and including communication counts that the subscribers have communicated using their radio terminals. A communication information receiver receives communication information on the terminal communications from a radio network controller for controlling the base stations. A priority decision unit updates the communication counts stored in the memory, based on the received communication information, and determines the priority order of the priority information in accordance with the updated communication counts.

  • Patent number: 7873063
    Abstract: In a cell management method and apparatus which can prevent a call loss generated in association with an increase of cell usage rate independent of a protection frequency bandwidth, cell usage rates of operating cells (at frequency Fo) are acquired. Narrower nonoperating cells (at frequency Fo) of the operating cell in which the cell usage rate indicates a high-load state are rendered an addition candidate and the operating cell is rendered a deletion candidate. A broader nonoperating cell (at frequency Fo) of the operating cell in which the cell usage rate indicates a low-load state is rendered an addition candidate, and the operating cell and other narrower operating cells belonging to the nonoperating cell are rendered deletion candidate.

  • Publication number: 20090323523
    Abstract: In order to prevent occurrence of congestion derived from an unexpected or temporary factor as much as possible, a computer is allowed to execute a process of acquiring actual operational information indicating an actual operational history of a mobile communication network; a process of acquiring setting data corresponding to station data set for each node of the mobile communication network; a process of extracting, on the basis of the actual operational information and the setting data, a node or a channel expected to have increase in traffic and a node or a channel having a margin in traffic; a process of creating station data optimized in consideration of change of traffic to be set for each extracted node; and a process of transferring the created station data to the corresponding node for update.

  • Publication number: 20080153470
    Abstract: A providing method of cell information in a mobile communication system includes the steps of calling an area map (MG) of a user area that includes a position designated by a user and its surrounding area, obtaining attribute information indicating a communication speed per mobile unit and whether or not high speed communication is supported for each cell that covers a part or a whole of the user area, and superimposing a cell range image (RY) that indicates a range of each cell on the area map (MG) to display in the state where a difference of contents of the attribute information is distinguished.
