Load balancing control method suitable for multi-beam satellite network

Abstract

Based on the condition of multi-beam cellular networking in the current satellite network, The invention provides a QoS (Quality of Service)-guarantee-based method for combining load balancing of adjacent beams and hopping beams. According to the method, the quality of service guarantee of users is considered, load balancing is carried out by utilizing the characteristic that multiple beams of theusers in the adjacent beam overlapping coverage areas can be unloaded, meanwhile, the problem that beam center users cannot be unloaded is solved by adopting a beam hopping technology, the packet loss rate of beams of the whole network is effectively reduced, and the effective throughput of each beam of the whole network is improved. By effectively utilizing idle resources of the whole network, the problem of resource distribution bipolarization caused by non-uniform user distribution is solved, the average packet loss rate of the network is effectively reduced, and the network throughput isimproved.

Description

technical field [0001] The present invention relates to resource management in the technical field of wireless communication, in particular to load balancing of a multi-beam satellite communication network, and more specifically, to a load balancing control method applicable to a multi-beam satellite network. Background technique [0002] Satellite communication has the advantage of not being restricted by geographical location and supporting users with different needs to access it anytime and anywhere. In recent years, the field of satellite communication has achieved unprecedented development, and users' business requirements for satellite communication networks are increasing day by day. However, unlike traditional terrestrial networks, satellites are limited in power, spectrum, and orbit. Therefore, when designing satellite networks, efficient resource management methods must be adopted to meet increasing user needs. [0003] Existing mobile communication satellites usu...

Problems solved by technology

However, due to the limitation of transponders on the star, at present, only two beams of different sizes can be supported, and the effect of load balancing is still limited

[0005] In addition, the current research on load balancing methods is based on ideal assumptions, without considering the user experience in actual services, and the QoS (Quality of Service Guarantee) guarantee requirements of different services, which is not very practical in actual networks
