Satellite-ground fusion network-oriented satellite-borne base station switching management method

Abstract

The invention relates to the field of satellite-ground fusion, in particular to a satellite-ground fusion network-oriented satellite-borne base station switching management method, which is applied among a satellite-borne base station, an original master control satellite and a target master control satellite and is used for realizing switching management of the satellite-borne base station under different satellite mobile subnetworks. The switching management method comprises the following steps: an original master control satellite of a satellite-borne base station establishes an auction model for switching selection; the original master control satellite initiates a switching application to a target master control satellite selected according to an auction model, the target master control satellite allocates resources, and meanwhile, the satellite-borne base station executes a switching process; and the satellite-borne base station and the master control satellite complete uplink and downlink data forwarding. Meanwhile, a switching selection algorithm is designed based on satellite measurement parameters, the switching frequency of the satellite-borne base station can be reduced, satellite node load balancing can be achieved, and service interruption is reduced.

Description

technical field [0001] The invention relates to the field of satellite-ground fusion, in particular to a satellite-ground fusion network-oriented switching management method for satellite-borne base stations. Background technique [0002] The satellite network can cover extreme and remote areas. In the prevention and rescue of major natural disasters, it can dynamically form a network to support emergency services according to the coverage requirements, and integrate the satellite network with the ground network to build a space-ground integrated information network to support diverse space network requirements. It has become a new trend in the development of space information networks. However, there are many differences between the satellite communication system and the ground mobile communication system in terms of deployment environment and channel propagation characteristics, which brings many challenges to the integration of the two. [0003] In the long run, it is a d...

Problems solved by technology

Due to the high-speed movement of the space-borne base station relative to the ground, the terminal will switch between the space-borne base stations. The space-borne base station and the main control satellite are in different orbits, and they will also move relative to each other. Therefore, the satellite-ground fusion network must Deal with the mobility management of spaceborne base stations, otherwise it will be difficult to guarantee normal communication requirements
