Abstract

The invention discloses an air-space-ground integrated network system architecture based on a near space platform and a design method, and belongs to the technical field of wireless communication, andthe design method comprises the following steps: S1, introducing a near space platform aircraft; S2, formulating a communication link frequency band planning scheme; S3, simplifying protocol design.When communication link selection is carried out, the communication link selection is carried out based on the principle of minimizing propagation time delay and routing hops according to the geographical location relationship and the service type of two users carrying out communication. According to the invention, the near space platform aircraft is introduced into the network system architecture; a satellite network and a ground network are fused; global coverage is realized; the communication service quality of a non-ground network coverage area is effectively improved, extremely high robustness is achieved, the rerouting rate, the switching rate, the system delay overhead, the system access capacity and the like can be remarkably improved by designing a simplified protocol process, a frequency band planning scheme and a link selection scheme, and the method is worthy of application and popularization.

Description

technical field

[0001] The present invention relates to the technical field of wireless communication, in particular to an architecture and a design method of an air-space-ground integrated network system based on a near-space platform. Background technique

[0002] Compared with traditional terrestrial mobile communication networks, satellite networks can achieve global coverage and are more robust, providing communication coverage for non-terrestrial areas, remote areas, and disaster areas. However, the satellite network has disadvantages such as large power loss, large time delay, large single-beam coverage and small capacity, which makes the upper limit of the communication service quality of the satellite network low. Therefore, it is necessary to design an integrated network that integrates the satellite network and the terrestrial network. Air base stations such as airships and balloons in near space, as communication nodes, have the advantages of both ground mobile c...
