Abstract
The present application provides a network access control method, apparatus, and device. The method includes receiving a discovery request sent by a first network function (NF) instance, where the discovery request includes an identifier of a second PLMN and an NF type of a to-be-accessed NF instance. The method further includes obtaining a to-be-accessed network slice identifier, and requesting a second network function management module (NFRF) corresponding to the identifier of the second public land mobile network (PLMN) for instance information of a second NF instance corresponding to the NF type of the to-be-accessed NF instance and the to-be-accessed network slice identifier, and sending the instance information to the first NF instance, to improve access reliability of NF instances between different PLMNs.
