Multilayered satellite network channel resource management method

Abstract

The invention discloses a multilayered satellite network channel resource management method. The method comprises steps as follows: a prediction model of the business volume of new calling users allowed to be accessed in a community in a period of time is proposed firstly, the business volume of the new calling users allowed to be accessed in the community in a period of time is predicated accurately, and decision support is provided for different users requiring access to multilayered satellite networks; channel resource allocation is performed on the multilayered satellite networks, and the channel resource utilization rate of the whole satellite network is increased; types and the downgrading number of downgraded users are judged with a game theory, and an improved upgrading and downgrading model determines a specific downgrading method of the downgraded users and access of the downgraded users after downgrading, so that the downgrading process is more reasonable and more transparent, and the overall user's satisfaction is improved while the access of high-priority users is guaranteed. According to the multilayered satellite network channel resource management method, the users with different priorities in the satellite networks are reasonably accessed to the multilayered satellite networks, the channel resource utilization rate of the whole satellite system is increased, the user's satisfaction is improved, the satellite channel resource waste is reduced, and the satellite communication efficiency is improved.

Description

technical field [0001] The invention relates to a method for managing channel resources of a multi-layer satellite network, which belongs to the technical field of satellite communication. Background technique [0002] Compared with other communication methods, satellite communication has a long communication distance (for example, the communication distance can reach up to 18,000km when using a stationary satellite), large coverage area, wide communication frequency bandwidth, large transmission capacity, flexible mobility, and stable and reliable communication lines. and other advantages. Since the 21st century, satellite communications have developed rapidly, playing a pivotal role in military communications, commercial communications, and personal communications. With the rapid development of 4G networks and the surge of mobile terminals, people have greater demands for multimedia services and data services, and the requirements for service quality are getting higher an...

Problems solved by technology

[0004] Technical problem: Aiming at the channel allocation problem of multi-layer satellite network, the present invention provides a multi-layer satellite network channel resource management method. The main technical problem solved by the present invention is that satellite network traffic prediction is inaccurate and cannot provide decision-making for user access Support; only consider the allocation of satellite channel resources in a single-layer satellite network, resulting in low utilization of satellite channel resources and low overall user satisfaction; the de-escalation model only considers user bandwidth and access time, and low-priority users The downgrade process is not clear, and user satisfaction after downgrade is not high
