A.88 Monitoring of data management for UDR

28.5523GPP5G performance measurementsManagement and orchestrationRelease 18TS

UDR provides data management services for the subscriber and application related data, including:

– Subscription Data,

– Policy Data,

– Structured Data for exposure,

– Application data: Packet Flow Descriptions (PFDs) for application detection and AF request information for multiple UEs;

– NF Group ID corresponding to subscriber identifier (e.g. IMPI, IMPU, SUPI).

The data management services provided by UDR allow to its consumer (e.g., UDM, PCF and NEF) to read, create, update, delete a particular set of data and subscribe/unsubscribe to notification of relevant data changes.

Users’ service may not be fulfilled due to a poorly performing (e.g. overloaded) data management service, therefore it is indispensable that the performance of data management services can be monitored.
