Detailed Description

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

The inventor finds that currently only network slices, i.e. 5G network slice, wireless network slice + transport network slice + core network slice, construct the whole 5G slice architecture, but for any user, the 5G network is only a bearer channel and is not the final destination, so the existing network slices are not true end-to-end. The N6 port of 5G (exit UPF to DN) does not carry any slice information, that the MEC as an application cannot be part of the core network slice; the MEC system not only has the MEC App, but also has the MEC platform of the service App, that is, not only the network requirement but also the application requirement, which is different from the pure network requirement of the 5G slice, so the MEC application slice should not be part of the 5G network slice from this point of view.

Based on the above research, the present disclosure provides an implementation method and system of application slicing, and a network architecture of the present disclosure is first described below with reference to fig. 1A to 1C.

As shown in fig. 1A, the MEC application slice management domain is added to the existing network architecture, and the MEC application slice management domain mainly includes 2 modules: an application management function (which may be referred to as MEC App-CSMF), and an application slice management function (which may be referred to as MEC App-SMF).

For example, instantiating a corresponding MEC APP according to a business requirement, and instantiating MEC Services serving the MEC APP at the same time.

The improvements to existing network architectures in this disclosure may be more clearly understood by parallel comparison with existing network sliced network architectures. As shown in fig. 1B, if from an end-to-end perspective, the MEC application slice should have a corresponding relationship with the 5G network slice, the whole includes: a service requirement layer and a slice management layer. The left side is the network architecture of the existing network slice, and the right side is the architecture of the newly added application slice. OSS (Operations Support System), NSMF (Network Slice Management Function), NSSF (Network Slice Selection Function), AN-NSSMF (Access Network-Network Slice Subnet Management Function), TN-NSSMF (Transmission Network-NSSMF, transmission Network-Network Slice Subnet Management Function), CN-NSSMF (Core Network-NSSMF, core Network-Network Slice Subnet Management Function), NFVO (Network Functions Virtualization editor), (R) AN Controller (wireless Access Controller), TN Controller, etc. may refer to the existing standard, and no longer described herein.

As shown in fig. 1C, on the basis of the MEC system architecture, an application management function and an application slice management function are added, as shown by the shaded portion. The application management function may be provided between the OSS and the MEO, or may be provided in the OSS.
