A method and device for accessing network slicing

Abstract

Provided are a method and apparatus for accessing a network slice, belonging to the technical field of communications. The method comprises: receiving a user migration notification sent by a management device; acquiring network slice selection assistance information (NSSAI) corresponding to a first network slice, wherein the first network slice is a network slice that a migrated user equipment needs to access again; and sending the NSSAI corresponding to the first network slice to the user equipment, wherein the NSSAI corresponding to the first network slice is used for instructing the user equipment to access the first network slice. According to the present disclosure, when the user equipment is migrated, the number of requests in a network can be decreased, and the influence on normal transmission service data is avoided.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a method and device for accessing network slicing. Background technique [0002] The fifth-generation mobile communication technology (fifth-generation, 5G) network has rich and diverse network services, and different network services have different requirements on the network; for example, network services such as automatic driving and remote control require the network to have ultra-low latency and Ultra-high reliability; network services such as Augmented Reality (AR) / Virtual Reality (VR) require the network to have ultra-high bandwidth; network services such as the Internet of Things (IOT) require the network to support a large number of devices access and ultra-low power saving. Therefore, in order to meet the requirements of different network services, the network is divided into multiple network slices, and different network slices are used to implem...

Problems solved by technology

[0006] After the UE detects that it is offline, it will repeatedly send access requests to the network slice within a preset period of time. In this way, when a large number of UEs in the network slice go offline at the same time, a large number of UEs will repeatedly send access requests to the network slice. The situation of incoming requests leads to a sudden increase in the number of requests in the network, and the network burden becomes heavier, which affects the normal transmission of business data
