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.

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.

Abstract: A communication control system includes a wireless base station A and a wireless base station B that control wireless communication of a mobile communication terminal and an EPC that performs path control and data transmission/reception control between the wireless base station A and the wireless base station B by wire communication. Then, when the wireless base station B receives a handover request requesting for switching the wireless path from the mobile communication terminal, the wireless base station B switches the wireless path to a wireless path through the wireless base station B, and after a predetermined time elapses from when the wireless path is switched, the wireless base station B transmits a request for switching a wire path through the wireless base station A that performs data transmission/reception control for the mobile communication terminal to a wire path through the wireless base station B to the EPC.

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.

Abstract: 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?PDU divider for dividing packet data to be transmitted to an opposite entity, into protocol data units; and a synchronous control signal generator 223 for 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.
