Abstract: This application provides a method for enabling an intent and an apparatus. The method includes: A first network element obtains first information, where the first information indicates at least one intent, and the at least one intent is all intents that conflict with a first intent. When the first network element determines that a status of the at least one intent changes, the first network element initiates a procedure of enabling the first intent. According to the solution of this application, when the first intent is in a conflict state, the first network element may initiate the procedure of enabling the first intent after determining that statuses of all the intents that conflict with the first intent change. The solution in this application can be used to re-initiate, in a timely, accurate, and efficient manner, the procedure of enabling the first intent.

Abstract: A method for associating intent knowledge between intent systems, an apparatus, and a system. When intent knowledge of a first intent in a first intent system is updated, a second intent system receives an intent knowledge update notification sent by the first intent system. The intent knowledge update notification includes an update type and an intent keyword of the first intent. The second intent system associates, based on the intent knowledge update notification, the intent knowledge that is of the first intent and that corresponds to the intent keyword of the first intent with intent knowledge of a second intent in the second intent system. In this way, the intent knowledge is associated between the intent systems, to avoid that the intent knowledge of the first intent in the second intent system is missing or invalid.
