Abstract

The invention discloses a VDE-SAT time slot mapping dynamic configuration method. The method comprises the following steps: S1, dividing a satellite communication global coverage area to obtain a plurality of acquisition areas, and obtaining original user feature data; S2, performing time slot mapping dynamic configuration based on the original user feature data to obtain time slot mapping dynamic configuration prior parameters in each acquisition area; S3, after a satellite rotates around the earth for one round, acquiring the plurality of acquisition areas again to obtain current user feature data in each area; S4, performing time slot mapping dynamic configuration based on the current user feature data to obtain current time slot mapping dynamic configuration parameters in each acquisition area; and S5, based on the time slot mapping dynamic configuration priori parameters and the current time slot mapping dynamic configuration parameters, carrying out weight distribution calculation to obtain a period number p as optimal channel mapping configuration. According to the invention, the utilization rate of the channel time slot in the VDE-SAT communication system can be effectively improved, the access number of users in unit time is effectively increased, and the access performance of the system is improved.

Description

technical field [0001] The invention belongs to the field of satellite communication, in particular to a dynamic configuration method for VDE-SAT time slot mapping. Background technique [0002] VDES (VHF Data Exchange System, VHF Data Exchange System) is an enhanced and upgraded system for the automatic identification system (AIS) in the field of maritime mobile services. It was proposed after the conference and was jointly deliberated and determined by 162 member states and 136 international organizations and groups at the 2015 World Radiocommunication Conference (WRC-15). On the basis of integrating the existing AIS functions, VDES adds special application messages (ASM) and broadband VHF data exchange (VDE) functions. VDE includes VDE-TER (VDE-Terrestrial, ground-based VDE) and VDE -SAT (VDE-Satellite, satellite-based VDE) two major systems. VDE-TER is responsible for ship-to-shore communication or ship-to-ship communication in offshore areas, and VDE-SAT is for remote...
