摘要： A data transfer system allowing high-quality transfer of streaming data through a network having a relatively large delay variation in data delivery is disclosed. When transferring streaming data in packets from a server computer to a client computer through a repeater provided in the network, the repeater buffers a streaming packet for a set time period before forwarding it to the client computer. The set time period is determined so that a receiving time interval of packets at the client computer is substantially equal to a sending time interval of packets at the server computer.

摘要： A managing server 1 and a propagation characteristic computing server 3 grasp a load situation for each cell that is a coverage range of each of a plurality of APs 4a to 4d, calculate an evaluation value defined for evaluating the load situation, and take a control of the load situation of each cell so that this evaluation value is minimized. The control of load situation is a control for altering a shape (including size) of each cell, and further, specifically, a control for making a cell alteration so that the above-mentioned evaluation value is minimized, by performing processes such as regulation of the transmission power of the AP, alteration of the installation position of the AP and addition of the AP. This allows the load of each cell (AP) to be regulated most suitably.

摘要： An area to be estimated is sectioned to minute sections, the received signal qualities from a plurality of installed base stations (51, 52) are found, respectively in each of the minute sections, a difference between the received signal quality of each minute section and the received signal quality of a minute section adjacent to the above minute section is referred to as well as a change point at which a difference between a received signal quality used as a hand-over condition and the above received signal quality changes is detected so that an area in which a hand-over occurs can be accurately estimated. With this manner, there can be obtained a received signal quality estimation method capable of estimating an area in which a hand-over occurs very accurately in a mobile communication system.

摘要： In a case of operating a wireless LAN system for covering a wide-range area employing a plurality of APs (Access Points), propriety of a coverage range of the AP is visually displayed together with its influence range on an area map with an operational situation based upon a load situation, an interference situation, a utilization situation of a channel, etc. reflected. Various kinds of operational information of a wireless appliance in a cell of each of APs 4a to 4c is collected by a managing server 1, and also, a cell boundary of each AP is determined by a cell boundary server 2. And, the managing server 1 works/computes the collected operational information, and finds the operational situation in each cell. And, a displaying apparatus 3 partitions a service area of the wireless LAN system with a cell boundary, and makes a display so that a display aspect thereof differs responding to the operational situation for each cell found in the managing server 1. This allows the display aspect that coincided with the operational situation to be obtained, thereby making it possible to display propriety of the operational situation for each cell coverage range by coverage range of the AP.

摘要： In a source node of a multi-hop network is provided with a route table in which a number of routes from the node to all destinations are mapped to hop count numbers. In response to a request for transmission of data, the node determines a hop count number from the route table corresponding to a route indicated in the request and segments the data into a number of data segments according to the hop count number. The data segments are converted into packets and transmitted. In a transit node, the packets are placed into one of a set of queuing buffers that corresponds to the hop count number of the packets. The stored packets are scheduled for transmission according to their hop count number.

摘要： A system is connected to an access point via a network, receives packet transmission information held by the access point, and extracts an address having a transfer destination which is radio interface from the packet transmission information. It is assumed that the terminal of the extracted address exists under the access point holing the packet transmission information. Thus, it is possible to realize connection relationship between a terminal and an access point at low cost and not depending on the vendor.
