Problems solved by technology

Therefore, if a user exaggerates his demand to the relay satellite system in reality, these resource allocation methods designed based on the assumption that all users cooperate may increase the selfish user’s income, which will not only damage the legitimate income of other users, but also Bring huge pressure to the resource conflict resolution work of the whole system

Embodiment 1

[0075] An embodiment of the present invention provides a resource management method for a relay satellite system. The method is applied to a relay satellite system service dispatch center (hereinafter referred to as the dispatch center). The relay satellite system executes the relay service strictly according to the time period , which is the basis of the repeated game architecture in the embodiment of the present invention. see figure 1 As shown, the method includes the following steps:

[0076] S11: Every other mission planning period, publish the available time resource information of the inter-satellite link antenna beam in the mission planning period to multiple user terminals.

[0077] Wherein, each task planning cycle includes: multiple time windows. In this embodiment, every other mission planning cycle, the dispatching center releases all available antenna beam resources of the system to each user end except for the beam resources necessary for the relay satellite s...

Embodiment 2

[0169] An embodiment of the present invention provides a relay satellite system resource management system, see Figure 10 As shown, the system includes: a relay satellite system service dispatching center 51 and a plurality of user terminals 52, the relay satellite system service dispatching center 51 communicates with a plurality of user terminals 52, and the relay satellite system service dispatching center 51 is used to execute The method described in Example 1.

[0170] In a specific implementation manner, it is assumed that there are 3 users participating in resource competition, that is, |U|=3.

[0171] Compare the following two situations: (1) All user cooperation mode, from the 1st to the 30th mission planning cycle, 3 users cooperate to abide by the pre-agreed rules, that is, each user sends 120 hours to the relay satellite system dispatching center Window requirements; (2) All users do not cooperate (current status), from the 1st to the 30th mission planning cycle,...

Abstract

The present invention provides a relay satellite system resource management method and system, which relate to the technical field of space information network. The method includes: every other mission planning period, releasing the information of the inter-satellite link antenna beam in the mission planning period to multiple user terminals Available time resource information; receive business demand application information sent by multiple clients; according to the time resource type in the available time resource information, perform business diversity on the business demand application information to obtain multiple business demand sets; according to the available time resource information , a set of service requirements and a first preset service scheduling strategy, and perform service scheduling on the service requirement applications of multiple user terminals. The present invention is based on a repeated game framework in game theory, through the cooperation mechanism among multiple users of the relay satellite system, effectively suppresses the selfish behavior of users in the process of application for business requirements, reduces the intensity of resource conflicts in the system, and combines efficient heuristics The business scheduling strategy significantly improves the service efficiency of the system.

Description

technical field [0001] The invention relates to the technical field of space information network, in particular to a relay satellite system resource management method and system. Background technique [0002] The tracking and data relay satellite system (TDRSS) uses geostationary or high-orbit relay satellites to track, measure, control and data relay target users such as low-to-medium orbit spacecraft and non-spacecraft platforms, and belongs to space-based information system. Compared with the ground-based system, the relay satellite system can greatly expand the measurement and control coverage of user targets and improve the timeliness of missions. [0003] In recent years, with the increase of space activities, the target users' demand for relay tasks has grown rapidly. How to efficiently manage the extremely limited relay satellite antenna beam resources is of great significance. In practical application, the development process of the relay satellite system has form...
