In the foregoing AI application scenarios, input of an AI model is access stratum (Access Stratum, AS) data of user equipment (User Equipment, UE). How to collect the AS data of the UE and report the AS data to an application layer is an urgent problem to be resolved. SUMMARY This application provides a data collection method and an apparatus. AS data of UE can be collected by using the method. According to a first aspect, a data collection method is provided. The method may be performed by a data collection application function network element, or may be performed by a chip or a circuit disposed in the data collection application function network element.

According to the foregoing solution, the event consumer application function network element may send an access stratum data collection requirement, which is needed for training a model by the event consumer application function network element, as subscription information (namely, the first information) to the data collection application function network element, the data collection application function network element sends the subscription information to the network device or the non-access stratum of the terminal device, the network device or the non-access stratum of the terminal device collects access data and forwards the access data to the data collection application function network element, and finally, the event consumer application function network element obtains a subscribed access stratum data collection result from the data collection application function network element, so that a procedure of collecting an access stratum measurement result by the event consumer application function network element is completed. With reference to the first aspect, in some implementations of the first aspect, the data collection application network element receives third information from the network device, where the third information indicates data that is in the first access stratum data set and that is accepted by the network device and/or data that is not accepted by the network device. According to the foregoing solution, after receiving the subscription information sent by the data collection application function network element, the network device may feed back a result of accepting the subscription information to the data collection application function network element. In a possible implementation, that the first access stratum data set includes the access stratum data that the event consumer application function network element requests to obtain includes: The first access stratum data set includes access stratum data corresponding to at least one event group subscribed to by the event consumer application function network element, each of the at least one event group corresponds to a part of the access stratum data in the first access stratum data set
