Abstract: A communication method and a communications apparatus, where the method may include: selecting or re-selecting, by a terminal device, from a first cell to a second cell through cell selection or re-selection, where radio access technologies of the first cell and the second cell are different, and where the terminal device is in an inactive mode in the first cell; re-selecting, by the terminal device, to the second cell through cell re-selection; and initiating, by the terminal device, a registration procedure after completing the cell re-selection. When the terminal device in inactive mode performs cell re-selection based on different radio technologies, the terminal device initiates the registration procedure or a service request procedure, for NAS signaling connection recovery. When the terminal device changes a radio access technology, a network device can update information.
