A base station apparatus includes a determining unit that determines whether a direct link has been established between the base station apparatus and another base station apparatus, when a mobile device makes a request to switch a communication recipient from the base station apparatus to the other base station apparatus; a link information acquiring unit that acquires, indirectly from the other base station apparatus, link information necessary for establishing the direct link to the other base station apparatus, when the determining unit determines that no direct link to the other base station apparatus has been established; and a link requesting unit that requests the other base station apparatus to establish the direct link to the base station apparatus, based on the link information of the other base station apparatus acquired by the link information acquiring unit.

Base station apparatus, communication control system, communication control method, and inter-station control method

A communication method in a communication system, wherein the communication system includes a mobile terminal, a communication server that distributes data to the mobile terminal, and plural base stations that are capable of relaying the data, and one of the base stations among the plural base stations is responsible for relaying the data. The communication method includes transmitting, to the communication server, restriction instruction information to restrict a data transmission rate, by a first base station that is responsible for relaying the data among the plural base stations, and hand-overing, by the first base station, causing a second base station different from the first base station to take over the responsibility of relaying.

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

Data transfer system, approach notification system and data transfer method

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. A priority information transmitter transmits the priority information stored in the priority information memory to the base stations.

Terminal regulation management device

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. From among the nonoperating cells that are the addition candidate and the operating cells that are the deletion candidates, a nonoperating cell(s) to be switched over to an operating cell(s) and an operating cell(s) to be switched over to a nonoperating cell(s) is determined.

Cell management method and apparatus

To provide a packet communicating apparatus that can reduce a padding area. A packet communicating apparatus used in a high speed packet communication in a radio mobile communication network includes: an SDU&#x2192;PDU divider for dividing packet data to be transmitted to an opposite entity, into protocol data units; and a synchronous control signal generatorfor jointly putting a control signal to change a protocol data unit length, on a padding area of a protocol data unit occurring at a time of the division.
