HeNB-GW user plane related measurements are used to measure data volume on S1 interface including incoming and outgoing of data packets and octets for GTP-U. When HeNB GW is present in HeNS, it is fairly a straightforward way to collect such performance data from HeNB GW. Especially, operators deploy a dedicated HeNS management system.

Based on that, the measurements are useful to analyze data volumes and velocity from HeNB-GW point-of-view. If the data volume is too high, more interface bandwidth should be deployed, or HeNB-GW load balance should be considered. If data velocity is too high, the packet forwarding capacity of HeNB-GW should be enhanced to avoid data congestion.

In addition, HeNB-GW user plane related measurements could be together with other performance measurements to analyze network performance to find out the abnormal events.
