METHOD FOR DYNAMIC BACKUP AND DISTRIBUTION OF CHANNEL THROUGHPUT IN SATELLITE NETWORK AND DEVICE THEREFOR Russian patent published in 2017 - IPC H04J4/00 

FIELD: physics, communications.

SUBSTANCE: invention relates to radio communication, particularly to a field related to methods, particularly methods for backup and distribution of throughput in satellite networks with transmission of multimedia packet traffic, which provides high efficiency of utilising throughput of satellite channels with acceptable transmission delay. Method comprises, in each active satellite terminal, performing classification of traffic according to discipline of service and type of backup (CRA, RBDC, VBDC), long-term statistical profile of the incoming aggregated traffic, determination of the short-term statistical profile of the aggregated traffic, determination of measurement parameters of the sample average and sampling variance of the bit rate of the incoming user traffic, measurement, on the selected period, of the sample average and sampling variance of the rate of the incoming user traffic, determination of parameters of the predicted dynamics of the conditional average and variance of the conditional average bit rate, based on the short-term statistical profile of traffic, expected lag time of backup and distribution, predicting the value of the conditional average and variance of the conditional average bit rate incoming at the input of the satellite traffic terminal, generating and transmitting to the central station a request for allocation of throughput with information on the predicted statistical traffic profile and backup parameters at the central station, taking into account statistical traffic profiles, determination of the optimum duration of timeslots for satellite channels of the network per transmission cycle, generation of the frequency-time schedule of transmission, sending the frequency-time schedules of transmission to the terminals.

EFFECT: developing a method and a device for dynamic backup and distribution of throughput resource in a satellite communication network, which enables to achieve high efficiency of utilising the frequency-time resource of the satellite communication network in conditions without traffic congestion due to minimum excessive backup of throughput while meeting requirements for average delay and delay jitter when transmitting aggregated packet traffic.
