5G wireless network virtualization system structure based on calculation and communication fusion

Abstract

The invention designs a 5G wireless network virtualization system structure based on calculation and communication fusion. The system structure gets through a resource barrier of a heterogeneous wireless network, shares an access network resource, breaks through a traditional honeycomb cell structure, and supports separation of a control plane from a data plane. Communication, calculation and storage multi-dimensional resources are considered to perform joint optimization, a network taking a user as a center is established, and a development need of a 5G system is finally adapted. The system structure is divided into three parts, i.e., a wireless physical network, a wireless virtual network and a core network. The wireless physical network part comprises infrastructure, resource pools and a physical network controller; and network resources are divided and stored according to a wireless resource, a computing resource and a storing resource, are placed into the corresponding resource pools, and are managed and controlled in a unified manner by the physical network controller. The wireless virtual network part comprises a plurality of virtual subnets and a virtual network controller, and the virtual network controller is responsible for coordination with the physical network controller and allocates the virtual subnets according to user needs.

Description

technical field [0001] The present invention designs a 5G wireless network virtualization architecture based on computing and communication integration, which is mainly applied to the fifth generation mobile communication system (5G) and belongs to the technical field of wireless communication. Background technique [0002] With the rise of smart terminals, tablet PCs, and social networks, the demand for mobile services will grow explosively, and wireless data traffic and signaling will have an unprecedented impact on mobile communication networks. According to the forecast of the International Telecommunication Union, by 2020, the demand for data service capacity of mobile communication networks will reach 1,000 times that of 4G commercial networks. 4G technology is difficult to meet the above development needs. On the other hand, the traditional cellular network is not particularly optimized for indoor scenarios, but now the proportion of indoor users of mobile applicatio...
