Slice management method, device, access network equipment and core network equipment

Abstract

Provided in an embodiment of the present invention are a slice management method, a device, access network equipment and core network equipment. The method comprises the steps of receiving a second uplink transmission request message sent by a first access network equipment after receiving a first uplink transmission request message sent by a terminal, the second uplink transmission request message carries the first identity recognition information of the first access network equipment; when the first identity information indicates that the first access network equipment is located in a specific area, indicating the terminal to access a specific slice of the specific area; according to the slice management method for the specific area, when the PDU session is established, through interaction of the terminal, the access network equipment and the core network equipment, the slice for establishing the corresponding scene is selected for the terminal, the slice is distinguished according to different service scenes and different access objects. The service guarantee and management of a specific scene, a specific area, a specific service and a specific terminal are realized, so that the purpose of differentiated services is realized.

Description

technical field

[0001] The present invention relates to the field of communication technologies, in particular to a slice management method and device, access network equipment and core network equipment. Background technique

[0002] Network Slicing refers to dividing an operator's physical network into multiple logically independent virtual networks on the same network infrastructure. Each virtual network has different functional characteristics and can flexibly respond to different needs and services. , these virtual networks are isolated from each other, and failure of one of them will not affect other virtual networks.

[0003] Network slicing provides end-to-end network-level services and differentiated services for different user groups. End-to-end network elements are specially combined to form a network that supports service isolation and other features. At the same time, through QoS (Quality of Service, service quality) and DNN (Data Network Name, data network nam...

Embodiment Construction

[0095] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0096]The slice management method provided by the embodiment of the present invention can mainly realize the slice management of the following 4 scenarios:

[0097] 1) There is only one specific slice in a specific area, and terminals entering this area can and can only access this specific slice;

[0098] 2) There is only one specific slice in a specific area, and a specific terminal entering the area can and can only access the specific slice, and other non-specific terminals cannot access the slice in this area, and can only make voice calls;

[0099] 3) Especially when there are multiple slice options (including a specific slice) in the area, the terminal preferentially accesses a specific slice, and changes to other slices when the terminal adjusts ...
