example 1

[0226] This example provides a network slice management system, including a network slice management functional entity, a subnetwork slice management functional entity, and a resource management and orchestration functional entity.

[0227] The network slice management functional entity can implement one or more of the following functional descriptions:

[0228] 1) Obtain the service requirement information of the user, and the user inputs the service requirement information and network capability requirement information through the open interface provided by the operator.

[0229] 2) Analyze the user's business demand information, and judge the service types and network slice types that the network can provide to the user;

[0230] 3) Design the topology / composition of the end-to-end network slice, and define the sub-network slices, network functional entities, and topological connections between the end-to-end network slices.

[0231] 4) Generate end-to-end network slice co...

example 2

[0241] Such as Image 6 As shown, this example provides a network slice creation method, including:

[0242] Step S1: The network slice management functional entity receives service requirement information input by the user.

[0243] The business requirement information includes but is not limited to one or more of the following:

[0244] The type of business that needs to be supported by the network, the scale of service, the priority of network slicing, the service quality of network slicing (such as bandwidth, delay, network capacity, number of shared by other network slices in the network).

[0245] Step S2: The network slicing management functional entity converts the service requirement information into network slicing requirements, and judges whether there is an end-to-end network slicing that meets the network slicing requirements, and if not, determines a network slicing template that meets the network slicing requirements. The step S2 may specifically include: the...

example 3

[0257] Such as Figure 7 As shown, this example provides a network slice creation method, including:

[0258] Step S21: The network slice management functional entity receives service requirement information input by the user.

[0259] The business requirement information includes but is not limited to one or more of the following:

[0260] The type of business that needs to be supported by the network, the scale of service, the priority of network slicing, the service quality of network slicing (such as bandwidth, delay, network capacity, number of shared by other network slices in the network).

[0261] Step S2: The network slicing management functional entity converts the service requirement information into network slicing requirements;

[0262] Step a: Determine whether there is already an instantiated network slice in the network that can meet the network slice requirements input by the user, and whether the user accepts sharing the network slice with other users, if ...

Abstract

The embodiment of the present invention provides a network slice management method and system, and a storage medium. The method applied to a network-side management system includes that a network slice management function entity determines a network slice template according to a creation requirement, wherein the network slice template includes a network slice description file and network slice maintenance management information; the network slice management function entity splits a network slice requirement corresponding to the network slice template into sub-network slice requirements; a sub-network slice management function entity obtains a sub-network slice template corresponding to the sub-network slice requirements, wherein the sub-network slice template includes a sub-network slicedescription file and sub-network slice maintenance management information; and a resource management and arrangement function entity allocates a virtualized resource to instantiate the sub-network slice description file and the network slice description file, and generates a sub-network slice and an end-to-end network slice.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a network slicing management method and system, and a storage medium. Background technique [0002] With the development of communication technology, network slicing appears. Network slicing is a set description of a series of network functions. Existing physical network resources are logically divided into different networks through network slicing. [0003] In the prior art, the network slices are deployed separately on specific network elements, and the network slices are relatively opposed to each other, and are only used for information exchange during application. In this way, the isolation of network slices set on specific network elements is only Some performance and error management can be done, but there is no way to uniformly manage all network slices of a certain service, so the network slice management is complicated, and the service quality is poor due to m...
