A control server, receives the number of user terminals U which have transited to the individual Web pages from a monitoring serverin Step S. In Step S, based on the received number of transitions U of the individual Web pages, application of control is decided by the control server. Here, based on the assumption that the number of transitions Uc to a Web page C including a transaction access or hyper link to the end serveraccurately represents the number of executed transactions, the number of transitions Uc to Web page C is compared with an upper limit value Cmax. When Uc&#x3c;Cmax, the process proceeds to Step Sand a control information is sent from the control serverto the user terminalsto cancel the application of control.

Transmission control system

A module transmits a request for line connection to a module at a communication time notified from a module. The module proceeds to line connection processing in response to the request for line connection and notifies the module of success or failure of line connection. The module notifies a log database of the notified success or failure of line connection. The log database records success or failure of line connection in a database as log data and notifies the module of the log data at predetermined time intervals. The module revises a communication time based on the log data and notifies the module of the revised communication time.

Wireless node

A throughput detectordetects a throughput R. A threshold value Rref of the throughput Rat which a network side can be presumed to be congested is stored in a threshold value storage unit. A comparatorcompares the current throughput Rwith the threshold value Rref. A release request unitrequests release of a wireless resource when the throughput Rfalls below the threshold value Rref. In response to the release request, a controllersuitably disconnects a physical layer or a logical layer of a wireless section to release the wireless resource. A release term determining unitdetermines a release term of the wireless resource. A resource request unitmakes the released wireless resource be acquired anew after the elapse of the release term to reconnect the wireless communication.

Traffic control method and apparatus for wireless communication

A communication permitted slot setting sectionrandomly and equally divides one prescribed cycle for each wireless terminal and sets some of them, respectively, as permitted slots 'p.' A communication assigning sectionassigns the total communication 'n' per one cycle pre-assigned to each wireless terminal to each permitted slot &#x201c;p.&#x201d; A communication timing determining sectionrandomly determines communication timings for each permitted slot &#x201c;p.&#x201d; A degree-of-congestion measuring sectionmeasures the degree of congestion of wireless resources. A connectivity estimating sectionestimates the connectivity M for each permitted slot. Each time a communication opportunity is consumed, a communication readjusting sectionassigns the communication opportunity to an permitted slot with a higher connectivity M at a higher probability in the next cycle.

Wireless terminal

An information collection device includes a signaling packet analysis section which extracts communication device information from a signaling packet, the communication device information identifying a communication device that transmits the signaling packet when connecting to another device.

Information collection device, communication error detection device, and computer program

Traffic control for a communication network using a token bucket. Tokens stored in the token bucket and data throughput to/from a data buffer are monitored, and a new token rate is determined based on the data throughput during the period that at least one token is stored in the token buffer.
