Vehicle-mounted satellite communication resource sharing system and method based on block chain

Abstract

The invention discloses a vehicle-mounted satellite communication resource sharing system and method based on a block chain. The vehicle-mounted satellite communication resource sharing system is composed of a plurality of vehicle-mounted satellite ground stations and a ground management center system. The ground management center system records a service identifier of each vehicle-mounted satellite ground station, and completes network access authentication in the block chain management system; collecting service statistical information of a vehicle-mounted satellite ground station; calculating the integral of each vehicle-mounted satellite ground station based on a block chain intelligent contract mechanism; and each vehicle-mounted satellite ground station compares the integrals of other vehicle-mounted satellite ground stations, and after data unification, synchronization is carried out among all the vehicle-mounted satellite ground stations. The method has the advantages that a decentralized shared vehicle-mounted satellite ground station ecological system is constructed, so that the problems of possibility of tampering centralized information and opaque information are fundamentally avoided, and shared behavior data are fully trusted by providers of a plurality of satellite communication ground station services; and the construction, operation and maintenance cost of network management is effectively reduced.

Description

technical field [0001] The invention relates to the field of vehicle satellite communication, in particular to a system and method for sharing resources of vehicle satellite communication based on block chain. Background technique [0002] Satellite communication has the advantages of large coverage area and long communication distance. In areas where terrestrial communications (such as 2G, 3G, 4G, 5G communications), optical fiber communications, etc. cannot be reached, satellite communications are the only means of communication; or in the event of sudden earthquakes, floods and other events, the public communications network may Devastating damage, paralyzing communications. Using satellite communication is an effective means to solve sudden communication paralysis. However, because the satellite is far from the ground and the signal power of ordinary computers and mobile phones is low, it is necessary to set up special satellite ground communication facilities, namely ...

Problems solved by technology

However, at present, all ground station construction is carried out by satellite operators in a "centralized" construction and operation mode, and traffic measurement and billing are all completed by satellite operators. Although satellite operators can formulate some commission models, according to The contribution of satellite communication ground station service providers (resource contributors) is calculated in points and subsidies are provided accordingly. It is impossible to measure the shared network resource services provided by itself, which inhibits people's enthusiasm for sharing network resources, and it is even more difficult to guarantee the service quality of shared satellite communication ground stations.
