A traffic data integration method includes: obtaining, by using a computer, pieces of frame data having a same data pattern between first and second traffic data collected respectively by first and second capture devices that capture, as traffic data, frame data communicated by a node in a network; performing, by using the computer, a time correction process by which a time of each piece of frame data in the first and second traffic data is corrected so that capturing times of pieces of obtained frame data are identical; using, by using the computer, frame data for which a same data pattern does not appear repeatedly in a same capture device, as frame data for performing the time correction process; and restricting, by using the computer, a time difference of frame data used when the time correction process is performed.

An interference control method including: receiving actual reception qualities of wireless signals that are measured by a wireless terminal, each of the wireless signals being sent from each of base stations, estimating future reception qualities after a specified period based on the actual reception qualities, estimating, for each of combinations of transmission powers of the base stations, corresponding interference based on the future reception qualities, and setting each of transmission powers of the base stations based on one of the combinations of transmission powers that is selected based on the corresponding interference.

Interference control method, interference control apparatus, and wireless communication system

A mobile radio communication system is provided for keeping high-quality communications and preventing disconnection of a radio link in fast movement. The system includes the radio network controller provided with a storage unit and a control unit. The storage unit stores grouped-user-equipments management information to be used for identifying and managing a plurality of user equipments as one group. The control unit controls the user equipments belonging to the same group so that they may be connected with their respective ones of the cells formed by the node bases. This allows the plurality of user equipments belonging to the same group to execute multiplex communications, thereby preventing simultaneous disconnection of the radio links of the user equipments belonging to the same group even when those user equipments are moving fast.

Mobile radio communication system

In a data transfer method and apparatus of the present invention, multiple data frames are received from a preceding node of a network of communication units, and the received data frames are routed to a next node of the network. It is detected whether each of the multiple data frames is addressed to another communication unit. It is detected whether the data frames that are detected as being addressed to another communication unit contain identical messages. The data frames that are detected as containing different destinations and identical messages are assembled into an integrated data frame, so that the integrated data frame is transmitted to the next node. A selected next-node equipment identifier is supplied, which indicates a selected next-node communication unit of the network that receives the integrated data frame. When the selected next-node equipment identifier and the integrated data frame are received, the integrated data frame is transmitted to the selected next-node communication unit via the network.

Data transfer method including recognizing identical messages and communication apparatus using the method

A device for controlling multi-window display on a screen includes a screen-operation detecting unit which detects user screen operations including a user operation of a pointer on the screen. The device further includes a control unit which controls a window to increase an amount of information displayed therein when said screen-operation detecting unit detects a move of the pointer into an area of the window.
