Network slice selection method based on NFV

Abstract

The invention discloses a network slice selection method based on a NFV. The method comprises the following steps: slices in the 5G network are divided into shared slices and private slices, thereby excellently satisfying different user demands under different scenes; furthermore, the existing network slices are maximally utilized by updating an available resource energy value in real time and expanding the capacity of the slices; the resource waste can be reduced, and the use ratio of the resource can be improved; for the situation that the existing network slices cannot satisfy the access ofa new user, the method provided by the invention can flexibly instantiate new network slice based on the NFV technology, thereby improving the system reliability.

Description

technical field [0001] The present invention relates to a method for selecting a network slice, in particular to a method for selecting a network slice based on NFV, which belongs to the field of communication technology and can be used in 5G to select a suitable network slice for massive devices. Background technique [0002] With the rapid development of mobile communications, the explosive growth of data traffic, the access of a large number of smart devices, and the continuous expansion of service types have resulted in an existing network that cannot meet the needs of 5G development. [0003] Specifically, 5G networks will respond to three types of scenarios: mobile broadband, large-scale Internet of Things, and mission-critical Internet of Things. The three application scenarios have different requirements for network services, as follows: [0004] 1. Mobile Broadband [0005] For 4K / 8K ultra-high-definition video, holographic technology, augmented reality / virtual re...

Problems solved by technology

[0017] (1) Users need to access a default network slice first, and then judge whether their business needs are met. If not, then re-connect to a new network slice, which will lead to a long backhaul cost and time delay, which cannot meet the needs of users in uRLLC (Ultra Reliable&Low Latency Communication, low-latency, high-reliability communication) scenarios;

[0018] (2) For users who have specific business needs and need customized services, it is not specified that these users need customized services, and proprietary network slices should be provided for them;

[0019] (3) Which specific network slice in the existing network slice set should the newly connected user connect to, it has not been explained, if it is allocated directly according to the above method, it will inevitably cause a great waste of resources;

[0020] (4) If the existing network slicing cannot meet the needs of users, what should be done, the above method is not specified, and its reliability cannot be guaranteed
