Problems solved by technology

However, when a spacecraft with an IP address is moving from one relay satellite coverage area to another relay satellite coverage area, the ground router cannot automatically change the routing path, resulting in the forward data not being automatically routed to the user. spacecraft phenomenon
Although the terrestrial cellular mobile communication system gives some similar inspirations, the topological structure and communication mode of the space-ground integrated IP network have their own characteristics. According to the topological structure characteristics of the terrestrial IP network and the engineering characteristics of the relay satellite system, A space-ground integrated IP network mobility management method based on relay satellites is proposed, which is suitable for routing control algorithms of different relay satellite network topologies, and solves the automatic switching of space-ground network links and dynamic routing repair caused by fixed IP mobility. question

Abstract

The invention provides a mobile IP communication system and method for relaying a satellite space-ground integrated network, belonging to the technical field of satellite communication. The switching controller uses the SNMP protocol to control the IP router: when the equipment in the user center needs to communicate with the equipment in the spacecraft, the switching controller selects the available relay satellites in real time according to the visual status information, and routes from the static route. The optimal routing path is determined in the table and dynamic routing table; based on this, a forward communication link is established for data transmission. The proposed static and dynamic routing control methods are suitable for different relay satellite network structures, with strong applicability, simple control and flexible implementation. The network link automatic switching and dynamic routing fixes the problem.

Description

Technical field [0001] The invention relates to a mobile IP communication system and method using a relay satellite system, and belongs to the field of satellite communication. Background technique [0002] In order to adapt to the emergence of large spacecraft with IP subnets represented by manned space stations, it is becoming more and more obvious how to connect the ground network with the spacecraft to form a space-ground integrated IP network. Due to its high coverage, high transmission rate, and high dynamic adaptability, the relay satellite system plays a huge role in satellite management and space information transmission, and is an important space infrastructure in the future space-earth integrated network. For the application of the world-ground integrated IP network based on relay satellites, the mobility management problem caused by the user spacecraft switching between multiple relay satellites is a key issue that must be resolved. First of all, when there are multip...
