Abstract: A communication method is provided, a first policy control network element sends a subscription message to a usage monitoring network element, where the subscription message includes identification information of a first slice and identification information of a terminal device, and the subscription message is for subscribing to usage status information of the terminal device in the first slice. The first policy control network element receives, from the usage monitoring network element, first indication information indicating that usage of the terminal device in the first slice is exhausted. The first policy control network element sends, to a mobility management network element, availability status information of the first slice indicating that the first slice is unavailable; or the first policy control network element sends a user route selection policy to the terminal device, where the user route selection policy does not include the identification information of the first slice.
