Abstract

The present disclosure provides a method, device and system for managing slice migration, and relates to the field of mobile communication. The slice manager determines that the slice needs to be migrated, determines the attribute of the slice to be migrated, and sends corresponding instruction information to the affected user terminal according to the attribute of the slice to be migrated, so that the user terminal can reselect the slice. Among them, if the slice needs to be migrated, it is only the slice-specific function sub-slice, and a session reconstruction request is sent to the affected user terminal, so that the user terminal initiates a PDN session to reselect the slice-specific function sub-slice used in the PDN session; Only slice-specific function sub-slices, and send re-registration requests to affected user terminals, so that user terminals can re-select corresponding functional network function sub-slices and slice-specific function sub-slices through re-registration. In this way, slice migration controlled by the network side can be realized, and while effectively improving system management efficiency, the impact of slice migration on users can be reduced.

Description

technical field [0001] The present disclosure relates to the field of mobile communications, and in particular to a method, device and system for managing slice migration. Background technique [0002] The concept of network slicing is introduced in the 5G system. Each network slice can have different mobility, security, delay, reliability, and even billing methods, which can better provide a wide range of connection services for all walks of life. . [0003] Users can access multiple network slices in the network at the same time. The network slice used by the user may include public network functions and slice-specific functions, where the public network function is a part shared by multiple slices accessed by the user at the same time. [0004] Users can migrate between slices due to, for example, user movement. Currently, the relevant technologies only consider how to handle when the user terminal actively initiates slice migration, but do not involve the situation wh...
