example 1

[0315] This example provides a network slicing application control method, which introduces management at the RAN level in addition to network slice availability management at the core network level. On the one hand, user equipment sends NAS messages through the core network to perceive the availability of network slices; on the other hand, RAN base stations implement availability control of network slices at the RAN level through slice configuration information. For example, the UE can perceive the availability of network slices at the RAN layer through various messages delivered by the RAN. In this example, both the core network and the RAN will manage the availability of network slices. In this way, it is avoided that the core network alone realizes the availability control of network slices, resulting in ignoring the unreasonable division and application of network slices, resulting in TA fragmentation It improves the effective utilization of network slicing and the balanc...

example 2

[0317] Base station description:

[0318] The base station sends the network slicing restriction policy to the user, including the adjacent cell or adjacent frequency or adjacent TA policy, and the specification can include the quality threshold for the network slice of the secondary station;

[0319] When receiving a terminal request or a core network construction request for a terminal-oriented network slice, it can be rejected based on the admissibility (reasons for the rejection include support by the secondary station but not by the terminal, or other reasons).

[0320] receiving information about network slices supported in the core network registration area sent by the core network;

[0321] Receiving information about the base station or cell, or the network slice (and characteristic information of the base station or cell) supported by the base station or cell (such as frequency network slicing support capability) sent by the base station;

[0322] According to the i...

example 3

[0324] Such as Figure 9 As shown, this example provides a network slicing application control method, including:

[0325] The base station broadcasts or unicasts the slice configuration information of the network slice to the UE; the slice configuration information may include: the current site or the current cell or the information of the network slice applicable to the receiving UE, the frequency band to which the network slice can be applied, the signal threshold, Neighbor list, TA list, etc.

[0326] The UE matches the availability information and slice configuration information of the network slice sent by the core network through the NAS message, and initiates a slice request;

[0327] The base station notifies the CN of the RAN-specific slice configuration information, which may specifically include: the corresponding relationship between applicable network slices and user capabilities such as terminal capabilities, or the relationship between network slices and cells...

The network slice application control method applied to the base station provided by the embodiment of the invention comprises the step of distributing slice configuration information of a wireless access network to user equipment UE.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a network slice application control method and device, communication equipment, and a storage medium. Background technique [0002] Network slicing is a virtual network that can perform specific functions or fulfill specific requirements with high quality after virtualizing network resources. [0003] In the prior art, the application and management of network slicing are implemented by the core network, and the core network notifies the user equipment (User Equipment, UE) whether the corresponding network slice is Information available. However, if the use of network slicing is completely managed by the core network, it may cause problems in the process of applying the corresponding network slicing in the Radio Access Network (RAN), and may result in a low success rate of sessions utilizing the network slicing. or poor session quality.
