Abstract

The present disclosure provides a template-based 5G end-to-end network slice generation method and a device. The method comprises: receiving a network slice generation request for generating a network slice; triggering, according to the network slice generation request, the use of a general template to generate an abstract topology corresponding to the network slice, the abstract topology describing a connection relationship between network function units; and mapping, by means of a mapping policy, the corresponding abstract topology to a physical topology, so as to generate the network slice. In the method, a general template is adopted for the same type of services having the same requirements to establish an abstract topology of a network slice, and the network slice is generated by means of mapping, thereby reducing the number of established network slices, optimizing a mapping relationship of network slices, and reducing the cost for establishing a network slice.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a template-based method and device for generating 5G end-to-end network slices. Background technique [0002] With the development of communication network technology, the fifth-generation mobile communication network (5G) has been born. While increasing the transmission rate, mobile network-based applications are becoming more and more abundant. In order to meet the differentiated needs of many applications, network slicing technology has become Ideal network architecture in the fifth generation mobile communication network. Network slicing technology can achieve logical isolation of communication networks, allowing network elements and functions to be configured and reused in each network slice to meet specific application requirements. [0003] However, currently, network slicing usually consists of a single virtual topology or a virtual network functio...
