COMMUNICATION METHOD, APPARATUS AND SYSTEM

This application discloses a communication method, apparatus, and system. The communication method includes: A second data analytics network element receives a status analytics output of a target object from a first data analytics network element, where the target object includes one or more of a network device, a sub-domain of a network, an all-domain of a network, or a terminal device. The second data analytics network element obtains, based on the status analytics output of the target object, first input data corresponding to a target type of analytics, where when the status analytics output of the target object indicates that the target object is in an abnormal state, the first input data does not include data corresponding to the target object. The second data analytics network element generates, based on the first input data, a first analytics output corresponding to the target type of analytics. When the status analytics output of the target object represents that the target object is in the abnormal state, the first input data does not include data corresponding to the target object. In this way, the first analytics output may not be affected by incorrect data corresponding to the target object, so that correctness of the first analytics output can be improved.
