Access satellite determining method and device

Abstract

The invention provides an access satellite determining method and device. The method comprises the steps of on the basis of history energy state parameters of to-be-accessed satellites, determining an energy state parameter of each to-be-accessed satellite in a current time slot; determining a state transfer parameter of user equipment accessing each to-be-accessed satellite in the current time slot; determining state transfer distribution condition of a satellite system composed of the to-be-accessed satellites according to the energy state parameters of the to-be-accessed satellites and the state transfer parameters of the user equipment; and establishing a decision-making model according to the state transfer distribution condition, and determining a target access satellite for accessing the current user equipment in the to-be-accessed satellites according to the decision-making model. According to the target access satellite determined through the method, the network capacity of a satellite system is optimized, and the energy of the satellite system is also optimized. The energy consumption of the determined target access satellite is low; the service life of the satellite system is prolonged; and the technical problem that the satellite system determined through an existing satellite access strategy is relatively high in energy consumption and short in service life is mitigated.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a method and device for determining access to a satellite. Background technique [0002] With the rapid development of the global economy and information exchange, more urgent requirements have been put forward for the efficiency, mobility and diversity of communication, which has made great progress in communication technology, and the terrestrial cellular network alone cannot meet the needs of social development. The combination of satellite communication network and ground mobile communication network will become an important part of the future personal communication system. In some important fields, such as space communication, aviation communication, maritime communication, military communication, emergency support, search and rescue, navigation and positioning, meteorology and telemetry and remote sensing, satellite communication cannot be replaced by other ...

AI Technical Summary

Problems solved by technology

Due to the complexity of the space environment, the conversion of solar energy into electrical energy is uneven at each moment, and for user equipment connected to satellites, it is unrealistic to clearly know the energy situation of each accessible satellite at each moment

[0005] The access satellite determined by the satellite access strategy in the prior art can achieve the optimal network capacity of the satellite system, but cannot achieve the optimal energy of the satellite system, and the determined satellite system consumes a lot of energy and has a short service life
