28.5523GPP5G performance measurementsManagement and orchestrationRelease 18TS

The UE location is required for various purposes, e.g., location-based applications, lawful interception, emergency calls, as well as the positioning services, etc.

The LMF manages the overall co-ordination and scheduling of resources required for the location of a UE for 5G. It also calculates or verifies a final location and any velocity estimate and may estimate the achieved accuracy. The LMF determine the result of the positioning in geographical co-ordinates.

The LMF provides location management related NF services (such as location determination, location notification, and location context transfer) in order for the consumer to get the location of the UEs. Therefore, the performance of location management related NF services need to be monitored in order to evaluate whether it can fulfil the consumer’s requirements, and to figure out the causes for the failures to derive the remedy solutions.
