1. A slice control method, the method comprising:
subscribing to a slice access control network element, by a policy control network element, for slice access status information of a network slice;
receiving, by the policy control network element from the slice access control network element, the slice access status information of the network slice;
determining, by the policy control network element based on the slice access status information of the network slice, that a network slice traffic bandwidth utilized by the network slice exceeds a corresponding bandwidth maximum value allowed by configuration;
generating, by the policy control network element in response to the determining, first session policy control information for a first session in the network slice; and
sending, by the policy control network element, the first session policy control information to a session management network element corresponding to the first session, the first session policy control information being for policy control on the first session.
