Aspects of the disclosure provide methods and apparatuses for network data analytics. In some examples, an apparatus includes processing circuitry. The processing circuitry transmits a network data analytics function (NWDAF) service discovery request to a network repository function (NRF) network element. The NWDAF service discovery request indicates a requested network data analysis service. The processing circuitry receives an NWDAF service discovery response in response to the NWDAF service discovery request. The NWDAF service discovery response includes performance parameter information of one or more NWDAF network elements for the requested network data analysis service. Further, the processing circuitry selects, according to the performance parameter information of the one or more NWDAF network elements for the requested network data analysis service, a target NWDAF network element used for providing the requested network data analysis service, and transmits an NWDAF service request to the target NWDAF network element.
