Abstract

Disclosed are a method and apparatus for using slicing information, and a device and a storage medium. The method includes: when first frequency point priority information and second frequency point priority information for a network slice are different, using the second frequency point priority information, or ignoring the first frequency point priority information, or updating the first frequency point priority information according to the second frequency point priority information. The first frequency point priority information is frequency point priority information saved by the terminal for the network slice, and the second frequency point priority information is frequency point priority information indicated or configured by a network side for the network slice.
