AI Technical Summary
Technical Problem
In NAT deployment scenarios, the network cannot recognize the private addresses of terminals, making it impossible to collect user application data.
Method used
By using network data analysis function network elements or authorized application function network elements, the identifier of the target user is determined, the protocol data unit session identifier is obtained, and user application data is collected through the terminal public address.
Benefits of technology
It enables the collection of user application data in NAT deployment scenarios, reducing the cost of modifying various network elements.

Abstract
The present disclosure provides a user application data collection method and device, electronic equipment and storage medium, and relates to the technical field of mobile communication. The method is executed by a NWDAF network element or a trusted AF network element, and includes: determining an identifier corresponding to a target user; sending the identifier to a UDM network element to obtain a protocol data unit session identifier corresponding to the target user; sending the protocol data unit session identifier to an SMF network element to obtain a terminal private address corresponding to the target user; sending the terminal private address to a UPF network element to obtain a terminal public address corresponding to the terminal private address; and collecting user application data through the terminal public address. The present disclosure determines the corresponding PDU session identifier through the identifier, and determines the terminal private address through the PDU session identifier. Then, the corresponding UPF network element can be used to match the terminal private address and the terminal public address. Therefore, the present disclosure realizes user application data collection.
