Abstract
This application discloses a network access method, apparatus, device, medium, and program product to reduce the load on the visited network AMF (Advanced Management Function) while improving network isolation and security. The method includes: receiving a registration request message sent by a base station, the registration request message being sent to the base station by a terminal device initially randomly accessing the network; determining, based on the registration request message, that the core network to which the terminal device belongs is different from its own core network; selecting a target AMF serving the terminal device, and forwarding the registration request message to the target AMF to request the target AMF to perform an authentication and authorization process with the terminal device.
