TECHNICAL FIELD Implementations of this application relate to the field of communications technologies, and in particular, to a data processing method and a system. BACKGROUND In a fifth generation (5th generation, 5G) communications network, a network data analytics function (network data analytics function, NWDAF) network element is introduced into a core network. The NWDAF network element obtains, by using a big data analytics technology, a data analytics result based on data of a terminal that is collected from one or more network elements, and feeds back the data analytics result to the network element for policy formulation. However, how the NWDAF network element associates the collected data is a technical problem that urgently needs to be resolved currently. EP 3 813 304 A1 relates to an information processing method and apparatus, to provide network side-expected terminal behavioral information with relatively high reliability.
