Abstract: A multistage relay communication system 100 includes a trunk network 1 and branch networks 2 (2a, 2b), each of which includes one or more communication apparatuses 4. The communication apparatus 4 can switch between a trunk mode to operate in the trunk network 1 and a branch mode to operate in the branch network 2. In the trunk network 1, the communication apparatus 4 carries out fixing of a communication path and redundancy of data based on a path table in order to achieve real-timeness and a data arrival rate. Meanwhile, in the branch network 2, when a communication failure occurs, the communication apparatus 4 autonomously searches for a communication path and constructs a path table, in order to at least secure a data arrival rate even if real-timeness is impaired within an allowable range.

A priority/filter type selection processing unit (37) of a network interconnection device (11), which connects a local network (14) and a wide area network (10), selects a transmission data selection processing unit (38) on the basis of the priority level definitions of a transmission data in accordance with an event status, and a data compression method in association with the event status and the wide area network communication status, and selects and controls a filtering processing unit (33). As a consequence, the communication bandwidth in a wide area network is reduced.

Abstract: In a wireless communications system operating according to CDMA or the like, when one terminal simultaneously performs communication using multiple wireless resources (e.g., multiple carriers), there was a problem that when it was attempted to guarantee network mobility by the same soft handoff system as in the case where communication was performed using only one wireless resource, efficiency suffered from the viewpoint of network forwarding load, processing load and wireless resource occupancy time. Soft handoff termination is judged and soft handoff is forcibly terminated according to whether or not the data rate obtained for all resources on the network side satisfies a requested rate, based on a reception state notification from a terminal concerning wireless resources.

Abstract: Even though a network with communication rate large fluctuations is applied to a remote monitoring system, data communication delay time is kept smaller for which a shorter communication delay time is demanded and a high throughput is implemented. A sensor equipped terminal sends measurement data to a network interconnection device. A priority level determining unit of the device sorts the data into first data necessary to be delivered to a monitoring center within requested communication delay time and second data not necessarily to be delivered to the center within requested communication delay time. A transmission buffer unit is a buffer storing the first and second data accumulated in first and second data accumulating units in sending the data to a wide area network by FIFO. A transmission control unit dynamically controls a rate in causing the data to come in the transmission buffer unit based on a network communication rate.

Abstract: In a remote monitoring system including a monitoring center, a sensing information collecting station, and one or more sensing terminals, the sensing information collecting station collects measurement results measured by the sensing terminals, classifies the collected measurement results into priority information and general information, and transmits priority information and general information to the monitoring center. The monitoring center transmits response information to received priority information to the sensing information collecting station. The sensing information collecting station estimates network condition from a delay time based on the response information and decreases the transmission rate of general information when the estimated network condition is more congested. Thereby, even if the network condition fluctuates, desired information such as statistical information on measurement results and measurement results meeting a predetermined condition is communicated stably at low delay.

The selections in the second control information are changed corresponding to selected first control information.
