6.2.4 Correlation between network data and service data
23.2883GPPArchitecture enhancements for 5G System (5GS) to support network data analytics servicesRelease 18TS
The Correlation information in input data which helps NWDAF correlate data from different NFs, OAM and UE application(s) is defined in Table 6.2.4-1, which is subject to all the network data analytics.
NOTE: For simplicity, the correlation information is not listed in the input data per network data analytics.
Table 6.2.4-1: Correlation Information
