摘要:
An approach for inter-gateway interference estimation and admission control is provided. A gateway receives return link signals, each being received via a satellite from a respective user terminal (UT) located within a satellite beam serviced by the gateway. A transmit power factor and an interference factor are determined for each UT based on the respective return link signal. A total interference factor is determined for the UTs based on the transmit power factors and the interference factors. A residual capacity level for the satellite beam is determined based on the total interference factor and a noise power factor. The gateway receives an admission request from a further UT requesting admission for transmission of a return link signal. The gateway determines whether to grant the admission request based on a required capacity level for the return link signal of the further UT relative to the residual capacity level.

An approach is provided for bandwidth allocation on a per terminal utilization and per inroute/inroute group basis, which optimizes bandwidth utilization. An aggregate average bandwidth usage of a plurality of remote terminals over a wireless communications channel is determined. A maximum rate for bandwidth allocations to each of the remote terminals for respective data transmissions over the channel is determined. A utilization metric reflecting a bandwidth utilization by one of the remote terminals for data transmissions over the channel is determined. An updated rate for bandwidth allocations to the one terminal is determined based on the utilization metric for the terminal, a target bandwidth utilization and tolerance range for the one terminal, and the maximum rate for the data allocations to each of the remote terminals. The updated rate for the bandwidth allocations to the one terminal is applied to subsequent bandwidth allocations for the one terminal.
摘要:
An approach for classification of a data traffic session over a data communications network is provided. A network device receives data packets of the data traffic session. The network device determines a plurality statistical factors that characterize the data traffic session based on the received data packets. The network device analyzes the determined statistical factors in relation to a plurality of classification variables, and classifies the data traffic session as being one of a plurality of session priority types based on the analysis, wherein each of a plurality of subsets of the classification variables delineates the plurality of session priority types over a continuum with respect to a corresponding one of the statistical factors.
摘要:
An approach is provided for delivering high throughput inroute bandwidth to a terminal in a shared bandwidth satellite communications system. A backlog level of each of a number of remote terminals is monitored, wherein the backlog level of each terminal reflects an amount of data traffic awaiting transmission via an inroute channel of the communications system. When it is determined that the backlog level of one terminal meets a first threshold level, the terminal is assigned to an express priority bandwidth allocation stage. The backlog level of the terminal is monitored while assigned to the express priority stage. When it is determined that the backlog level of the terminal has fallen below a second threshold level, the terminal is removed from the express priority stage. Further, a probability is applied to a qualifying terminal, where the probability controls whether the terminal is assigned to the express priority bandwidth stage.
摘要:
A system for scheduling prioritized traffic in a scrambled and coded multiple access (SCMA) system multiple terminals and a gateway. Each terminal is configured to receive packets from user devices and place the packets on various input queues. The packets are en-queued onto a plurality of output queues based on priority or service class. The terminal is further configured to detect one or more available SCMA slots within a frame of a communication system, and de-queue packets from the highest priority output queue onto the frame via one or more SCMA bursts. The terminal includes transceiver for transmitting/receiving frames of the communication system to/from the gateway. The terminals autonomously transmit SCMA bursts relative to each other.
