1. A communication method, wherein the method comprises:
determining, for a terminal and by an access network device, whether adjusting a resource of a slice accessed by the terminal is required based on a network spectrum resource usage status;
sending, by the access network device in response to a determination that adjusting the resource of the slice accessed by the terminal is required based on the network spectrum resource usage status, a slice resource adjustment message to the terminal, wherein the slice resource adjustment message comprises target resource information, and wherein the slice resource adjustment message is used to instruct the terminal to adjust the resource of the slice currently accessed by the terminal to a target resource; and
receiving, by the access network device, a slice resource adjustment complete message sent by the terminal, wherein the slice resource adjustment complete message is used to indicate that the terminal has adjusted the resource of the slice currently accessed by the terminal to the target resource.
