Problems solved by technology

However, in the satellite-ground collaborative network proposed by this invention, the structure of the control layer, the application layer, and the data layer are overlapped, so that the resources of each layer are overlapped. The common resource allocation method is difficult to take into account the global resources and the control delay is relatively large. , which leads to low resource utilization and a lot of traffic congestion

Abstract

The invention discloses a global load balancing satellite-ground cooperative network networking device and a method. The device comprises a multi-domain controller and a single-domain controller. Thesingle domain controller includes a satellite network controller and a ground network controller. The satellite network controller is used for managing and controlling a satellite access network, processing the service within the satellite network domain and reporting the cross-domain service; a terrestrial network controller is used for managing and controlling a plurality of terrestrial core network elements, processing services within the terrestrial domain and reporting cross-domain services. The multi-domain controller is used for controlling a plurality of single domain controllers, receiving the reported cross-domain traffic, and processing the cross-domain traffic through the global load balancing strategy. The method comprises the steps of processing intra-domain traffic by a single domain controller, processing cross-domain traffic by a multi-domain controller, and the like. The invention effectively utilizes various heterogeneous resources of the ground network, the satellite network and the server node, realizes the cross-layer optimization of the heterogeneous resources, reduces the total blocking rate, and improves the service response efficiency in the satellite-ground cooperative network.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a global load balancing satellite-ground collaborative network networking device and method. Background technique [0002] With the rapid development of 5G technology, global communication technology has a higher transmission speed, but at the same time, global communication has higher and higher requirements for coverage. The satellite network can provide global signal coverage and is less affected by the geographical environment. The combination of 5G technology and satellite communication has gradually become one of the focuses of communication technology development. [0003] The space network is mainly divided into the airspace network and the regional network. The regional network is composed of the traditional ground network, and the airspace network is mainly composed of the satellite network. The satellite network consists of geostationary orbit satellites (GEO),...
