Abstract: This application provides a communication method and a communication apparatus, and is applied to a scenario in which a terminal device registers with a home network separately via a first mobility management function network element and a second mobility management function network element. When determining that the second mobility management function network element is capable of performing primary authentication on the terminal device, the home network element sends, to the first mobility management function network element, a notification message indicating to delete a first pending flag, to avoid re-triggering primary authentication on the terminal device when the terminal device subsequently accesses the first mobility management function network element again. This reduces signaling overheads.
