摘要： In response to call requests from a source data terminal, a source earth station establishes first logical channels between it and the source data terminal and establishes logical links from the first logical channels to destination earth stations via a communications satellite. The destination earth stations establish second logical channels from the logical links to the destination data terminals. Each earth station performs flow control on each of the respective logical channels on a per message unit basis and performs flow control on each of the logical links on the basis of per plural consecutive message units to provide high throughput on the satellite channel.

摘要： A method for evaluating the performance of a wireless LAN (local area network) system having a single access point and a plurality of transmission terminals, which share the same radio channel, comprises the steps of dividing the plurality of transmission terminals into groups in accordance with radio conditions, calculating a transmission probability and a post-transmission failure probability for each group using a transmission rate, an error rate, and the number of terminals of each group, and calculating a throughput based on the transmission probability and post-transmission failure probability. A characteristic value for packet transmission delay may also be calculated based on the transmission probability and post-transmission failure probability. According to this method, the performance such as the throughput and the packet transmission delay can be evaluated in a wireless LAN system even before the wireless LAN system is constructed.

摘要： A data packet transmitted from a source data terminal is received by a destination data terminal and stored into a receive buffer from which it is withdrawn at a rate which may differ from the rate of transmission of packets from the source terminal. The destination terminal returns an acknowledgment packet in response to each data packet being withdrawn from the receive buffer. The acknowledging packet includes a flow control variable which is incremented by a unit value in response to the data packet being withdrawn from the receive buffer. The source terminal transmits one or more data packets having sequence numbers the largest of which is determined by a maximum number of outstanding data packets awaiting receipt of the acknowledging packet by the source data terminal and the flow control variable contained in the acknowledging packet.

摘要： In a multipoint communication system, first polling signals are sequentially and respectively transmitted to terminal stations on a broadcast channel from a central station, asking a request for reservation without waiting for a reply from the terminal stations. A reservation signal is transmitted on a multiple access channel from a terminal station requesting the reservation to the central station in response to the first polling signal addressed to it. A second polling signal is then transmitted on the broadcast channel in response to the reservation signal and the multiple access channel is reserved for a period of time variable in accordance with the reservation signal. A data signal is transmitted from the terminal station requesting the reservation on the reserved multiple access channel in response to the second polling signal.
