A communication method includes receiving, by a second data analytics network element, a status analytics output of a target object from a first data analytics network element. 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 communication method also includes obtaining, by the second data analytics network element based on the status analytics output of the target object, first input data corresponding to a target type of analytics. The status analytics output of the target object indicates that the target object is in an abnormal state, indicating that the first input data does not comprise data corresponding to the target object. The communication method further includes generating, by the second data analytics network element based on the first input data, a first analytics output corresponding to the target type of analytics.
