6G-oriented air-space-ground integrated network architecture and implementation method

Abstract

The invention provides a 6G-oriented air-space-ground integrated network architecture and an implementation method, and belongs to the field of mobile communication network architectures. According to the invention, based on further evolution of the existing 5G architecture, functions of part of network protocol stacks are modified, and a 6G-oriented air-space-ground integrated network architecture is realized. Partial functions in the AAU are virtualized and combined with the DU, and AD, DA and RF functions are reserved to form the RU network element; separating a control plane and a data plane of a CU network element, performing function recombination on the CU control plane and an AMF of a core network, and forming a new network control plane with an original core network control plane; and performing function recombination on the CU data plane and the UPF of the core network, and forming a new network user plane together with the DU. According to the invention, the access network and the core network in the air-space-ground integrated network are fused and deeply flattened, the air-space-ground integrated network architecture for 6G is realized, the flexibility of the network is improved, and the processing time delay of the network is reduced.

Description

technical field [0001] The invention belongs to the field of mobile communication network architecture, and specifically relates to a network architecture technology integrating an access network and a core network. The architecture is applied to the networking and operation and maintenance of a 6G air-space-ground integrated network. Background technique [0002] The evolution of mobile communication technology evolves along the two lines of technical system and business system. First of all, the business system is evolving from 2G voice and short message, 3G multimedia, 4G mobile Internet to 5G Internet of Things business. Secondly, technological system evolution: 2G circuit switching, 3G circuit switching plus packet switching, 4G all-IP flat structure, 5G introduces SDN / NFV, network slicing, and microservice-based architecture (Service Based Architecture, SBA) 1. The access network introduces the technology of CU / DU separation. The evolution of the technical system is ...

Problems solved by technology

The first type is the transparent elbow forwarding mode. The 5G base station gNB does not go to the satellite. It is located in the NTN gateway station of the ground satellite network. The satellite does not have on-board processing capabilities. For mobility management, data routing and other functions must be transmitted back to the ground, so High round trip delay

The second type is the regenerative mode. The satellite is fully or partially equipped with 5G base station gNB, and the access network and core network management plane are located on the ground. Therefore, the processing delay for routing, mobility management and other functions is relatively high, and the deployment cost is relatively high.
