A.36 Monitoring of PDCP data volume per interface

28.5523GPP5G performance measurementsManagement and orchestrationRelease 18TS

In 5GS, PDCP data volume is a useful measurement which represents the real data traffic towards each GNBDUFunction (F1-U interface), each external gNB-CU-UP (Xn-U interface) and each external eNB (X2-U interface). The monitoring of the PDCP data volume could provide operators with traffic information and is a useful measure in performance assurance within integrity area (user plane connection quality) and in energy efficiency evaluation.
