1. A communication method, wherein the method comprises:
determining, by a first access device, a first resource when the first access device is to send a paging message to a first terminal device in an inactive state, wherein the first resource carries a first wake-up signal, and the first wake-up signal indicates the first terminal device to detect downlink control information for scheduling the paging message that is carried in a first paging occasion resource;
sending, by the first access device, the first wake-up signal to the first terminal device on the first resource;
sending, by the first access device on the first paging occasion resource, the downlink control information for scheduling the paging message; wherein the method further comprising:
receiving, by the first access device, second indication information sent by a core network device, wherein the second indication information indicates a first terminal device group to which the first terminal device in the inactive state belongs;
determining, by the first access device, the first terminal device group based on the second indication information, wherein the first terminal device group is one terminal device group in one or more terminal device groups, wherein each of the one or more terminal device groups corresponds to one wake-up signal, and wherein the first wake-up signal corresponds to the first terminal device group; and
sending, by the first access device, seventh indication information to a second access device, wherein the second access device is an access device in a radio access network notification area (RNA) of the first terminal device, and the seventh indication information comprises at least one type of the following information:
a value of a parameter of the first terminal device, the first wake-up signal, an index value of the first wake-up signal, grouping information of terminal devices, and information about the wake-up signal corresponding to each terminal device group.
