Virtual bus-based distributed asterism network resource management method

Abstract

The invention relates to resource management technologies in the satellite communication field, and discloses a virtual bus-based distributed asterism network resource management method. The method comprises a first step that all resources in the distributed asterism network, including frequency, power, time slot, wave beam, a repeater, computing, storage, antennas and so on, are gathered in a distributed registration service center through the virtual bus, so as to form a unified resource pool to be dispatched and allocated uniformly by a specific resource management unit; a second step that a user sends a resource request, the resource management unit makes a resource allocation strategy according to a certain criterion in the resource pool, and broadcasts the strategy to all resource service nodes, a user and the registration service center, the resource service nodes allocate the resource according to the strategy, and the registration service center updates the state of the resource pool through the virtual bus; and a third step that after communication is finished, the user releases satellite resources according to a specific strategy. Through adoption of the method, the asterism resources are unified, so that optimum allocation of the network source is easy to realize.

Description

technical field [0001] The invention relates to the technical field of satellite communication systems, in particular to a method for allocating and managing distributed satellite communication resources. Background technique [0002] Satellite communication has the characteristics of wide coverage, high transmission rate, stable transmission channel, and less affected by terrain. Compared with other communication systems such as short wave and ultrashort wave, it has significant advantages. The rapid development of broadband multimedia services with data as the core has put forward the demand for large capacity, high bandwidth and higher QoS guarantee capabilities for satellite communication systems, while the level of on-board components and long-life requirements make the risk of large spacecraft difficult in the short term. avoid. Using a distributed constellation network composed of multiple small satellites and co-orbit coordination technology can effectively alleviat...

AI Technical Summary

Problems solved by technology

[0003] There are great differences in the QoS requirements for different service types in the distributed constellation network. The traditional resource scheduling method for a single satellite and a single satellite network system is difficult to meet these differentiated user needs at the same time.

On the other hand, satellites distributed independently in a wide area in space make the resources of the entire constellation network have relatively large non-uniform characteristics, and the phenomenon of resource islands is more serious.

The traditional distributed wireless resource management and allocation strategy usually considers the needs of individual users, but does not consider the actual availability of resources in the entire network. Such an allocation strategy will cause some resources with better local quality to be allocated to the current application, while some resources in the entire network will be allocated to the current application. Internal resources with better quality are idle, and the spectrum resources of the entire system have not been effectively utilized
