Space-ground integrated carrier-class satellite mobile communication system architecture and implementation method

Abstract

The invention discloses a space-ground integrated carrier-class satellite mobile communication system architecture and an implementation method. The system is composed of a plurality of satellites in a space section, an operation and maintenance management and control center and a plurality of gateway stations in a ground section, and a plurality of user terminals deployed on land, on the sea and in the air in a user section. A plurality of satellites in a space segment carry out splicing coverage on a ground target coverage range, a plurality of gateway stations are dispersedly deployed according to needs and support cross hot standby of key equipment, and an operation and maintenance management and control center carries out satellite-ground integrated operation maintenance and management control on the satellites, the gateway stations and user terminals; and for various complex use scenes, a network is flexibly established according to different application plan modes to provide high-quality comprehensive guarantee for users, and continuous learning updating of application plans is supported. According to the invention, resource comprehensive networking of multiple satellites is supported, and the expandability is good; mutual backup of multiple gateway station equipment levels is supported, and the reliability is high; and continuous updating of multiple application modes is supported, and the adaptability to complex scenes is good.

Description

technical field [0001] The present invention relates to the technical field of satellite mobile communication, in particular to an architecture and an implementation method of a space-ground integrated carrier-grade satellite mobile communication system. Background technique [0002] Compared with the terrestrial mobile communication system, the satellite mobile communication system has the obvious advantages of wide coverage and no limitation of terrain conditions. Disasters play an irreplaceable role in damage to terrestrial communication infrastructure. However, the coverage of a single satellite is limited. In order to provide mobile communication protection in a large geographical area, the actual satellite communication system often uses multi-satellite joint coverage and networking to provide communication services (such as Thuraya system, maritime satellite system). At the same time, in order to provide a service quality similar to that of the terrestrial mobile com...

[0003] Chinese patent CN110493791A proposes an architecture and design method of an air-space-ground integrated network based on a near-space platform. By introducing the near-space platform aircraft into the network architecture, global coverage is achieved, but the satellite communication system is not considered in the space-ground integrated communication network. The role in the network; Chinese patent CN105553711A proposes a network architecture and method to realize the integration of land, sea, air and sky networks. By dividing the network into a core network and an access network, an integrated inter-network interconnection is realized. , the above-mentioned patents mainly conduct research on network identification and management systems at the network level, and do not involve specific communication systems and application scenarios
