Data processing method and device

Abstract

The embodiment of the invention provides a data processing method and device, and relates to the field of communication. The method comprises the steps that a first network data analysis network element determines identification information of one or more sub-models related to a target model; for the network element corresponding to the identification information of the sub-model, the first network data analysis network element sends the identification information of the sub-model to the network element; and the first network data analysis network element receives an influence value for reflecting the sub-model on the target model from the network element, and further performs training to obtain the target model. According to the embodiment of the invention, under the condition that the plurality of network elements do not exchange the original data, the target model can be trained by using the output result which is calculated by the plurality of network elements and is used for reflecting the influence value of the local model in the network elements on the target model, so that data leakage is avoided, and the more comprehensive and accurate target model can be obtained; therefore, accurate data collection, data analysis, training and other functions can be provided.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a data processing method and device. Background technique [0002] The third generation partnership project (3rd generation partnership project, 3GPP) standard starts from R15, and introduces network data analysis function (network data analytics function, NWDAF) network elements in the communication network, and NWDAF network elements are used to provide data collection and data analysis , training and other functions, NWDAF network elements can provide network function (network function, NF) network elements or third-party application function (application function, AF) network elements or operation, administration and maintenance (operation, administration and maintenance, OAM) network elements in the network ) The network element feeds back the data analysis result, so that the NF network element, the AF network element, or the OAM network element implements or enha...

AI Technical Summary

Problems solved by technology

[0003] Usually, due to various privacy or security reasons, the data between the operator's network and the third party is usually not fully open, and even the data between domains within the operator's network cannot be fully open, which leads to data isolation problems

[0004] The problem of data isolation leads to difficulties in the usual data collection and centralized data analysis training, and NWDAF network elements cannot provide more accurate data collection, data analysis, training and other functions
