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 a tracking and data relay satellite space-earth integration network, which belong to the technical field of satellite communication. A handover controller uses an SNMP protocol to control an IP router; when a device in a user center needs to communicate with a device in a spacecraft, the handover controller selects an availabletracking and data relay satellite according to visual status information, and an optimal routing path is determined from a static routing table and a dynamic routing table; and thus, a forward communication link is built for data transmission. The provided static and dynamic routing control method is strongly adaptable to different tracking and data relay satellite network structures, the controlis simple, the realization is flexible, network devices in the tracking and data relay satellite system can be managed, and the problems of space-earth network link automatic switching and dynamic routing repair brought by movement of a fixed IP can be solved.

Description

technical field [0001] The invention relates to a mobile IP communication system and method using a relay satellite system, belonging to the field of satellite communication. Background technique [0002] In order to adapt to the emergence of large-scale spacecraft with IP subnets represented by manned space stations, the transmission requirements of how to connect the ground network with the spacecraft to form a space-ground integrated IP network are becoming more and more obvious. 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-ground integrated network. For the application of space-ground integrated IP network based on relay satellites, the mobility management problem caused by the switching of user spacecraft among multiple relay satellites is a key problem that must be solved...
