A.25 Monitoring of PDCP data volume measurements

In 5GS, Cell PDCP data volume is a useful measurement which represents the real data traffic for each cell. The monitor of the Cell PDCP data volume could provide operators the traffic information and is useful for operators to do cell load evaluation, load balancing and cell capacity planning.

In addition, in scenarios of dual connectivity, for split bearers, PDCP data is transferred between the MN and the SN via the MN-SN user plane interface. To monitor the real PDCP data volume transmitted in MN and SN in MR-DC scenarios, the data volume transferred between MN and SN should be counted.
