Title: CORE NETWORK CONTROL PLANE DEVICE SELECTION METHOD AND APPARATUS
Abstract:
Provided are a core network control plane device selection method and apparatus. The method comprises: a source core network control plane device obtaining first network slice selection auxiliary information about a terminal device; and if the source core network control plane device cannot determine a target core network control plane device indexed by means of the first network slice selection auxiliary information, the source core network control plane device sending the first network slice selection auxiliary information and first indication information to the terminal device, so as to trigger the terminal device to send a first registration request message, wherein the first indication information is used to indicate that a temporary identifier of the terminal device is invalid, and the first registration request message carries the first network slice selection auxiliary information and a permanent identifier of the terminal device. The core network control plane device selection method provided in the present application improves the security of a network slice and the efficiency of the redirection process of the terminal device, thus saving on signalling.
