A fundamental measure of QoS is the throughput (data rate) of the cell. The total cell throughput measured across all radio bearers gives an indication of the loading and activity in the cell. Adding a per QCI counter allows the loading on the different QCIs to be measured. For example, if QCI 1 is used exclusively for VoIP then the loading of conversational speech can be directly determined. The maximum throughput can indicate to the operator whether there is enough capacity in the network. Separate counters should be configured on the downlink and uplink. The PDCP SDU bit-rate helps to evaluate the usage of bandwidth and radio resource. Operators could perform network optimization based on the throughput statistics. Hence it is important to monitor the total cell throughput.
