Multi-dimensional end-to-end network slice generation device and method

Abstract

The invention discloses a multi-dimensional end-to-end network slice generation device and method. The problems that in the prior art, a user plane only sends a slice request, slices are not created,resource division is not thorough enough, and the generated general abstract topology cannot accurately reflect the actual connection situation between network function units are solved. The method comprises the implementation steps of: (1) creating an application container, (2) generating a user plane network slice, (3) dividing a virtual network according to a flow space rule, (4) generating a control plane network slice, and (5) generating a multi-dimensional end-to-end network slice. In the process of designing the multi-dimensional end-to-end network slice generation device and method, network slices are generated from two dimensions of a user plane and a control plane, and functionally and logically isolated end-to-end network slices are generated.

Description

technical field [0001] The present invention belongs to the technical field of communication, and further relates to a multi-dimensional end-to-end network slice generation device and method in the technical field of wireless communication. The present invention constructs a multi-dimensional end-to-end network slice by dividing the network slice into two dimensions: user plane network slice and control plane network slice. The end-to-end network slice can be virtualized on a unified physical network infrastructure. Instantiate multiple logical networks, create logically isolated network slices in terms of functions and resources, and realize network isolation of different types of network slices in the fifth generation mobile communication network 5G (the fifth generation). Background technique [0002] With the development of communication network technology, services in 5G networks are becoming more and more diverse. Compared with traditional networks, end-to-end network ...

Problems solved by technology

The disadvantage of this method is that when the network slice generation device receives multiple network slice generation requests with similar network requirements, it will use the same general template to generate the same type of abstract topology according to the slice generation request. The abstract topology is based on the mapping The strategy maps the same type of abstract topology to the physical topology to generate the same type of network slices

The disadvantage of this device is that, for the generation module, the general template is used to generate the abstract topology corresponding to the network slice, and the general abstract topology generated by the generation module cannot accurately reflect the actual connection between the network functional units

The disadvantage of this method is that this method needs to accept the slice request from the user plane, and then obtain the slice identifier through the network function virtualization orchestrator of the control plane to create a network slice

The disadvantage of this system is that the system needs to request the acquisition unit to send the creation instruction, and then the instruction sending unit selects the network function virtualization orchestrator to create the network slice. Request, resource division is not thorough enough

Moreover, it takes a long time to complete the creation of network slices, the user waits for a long time, and the time complexity is high
