Title:
METHOD FOR OBTAINING SLICE INFORMATION AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/183317
Kind Code:
A1
Abstract:
Embodiments of the present application relate to a method for obtaining slice information and a terminal device. The method comprises: in response to a Non-Access Stratum (NAS) of a terminal device receiving allowed Network Slice Selection Assistance Information (NSSAI) or updating the allowed NSSAI, the NAS of the terminal device sends slice information expected to be used to an Access Stratum (AS) of the terminal device; and the AS of the terminal device receives and stores the slice information expected to be used so as to use the slice information expected to be used during cell selection or cell reselection, wherein the slice information expected to be used is the allowed NSSAI or a subset of the allowed NSSAI. The embodiments of the present application can enable the AS of the terminal device to always store the slice information expected to be used, such that cell selection or cell reselection can be performed according to the slice information expected to be used.
