Abstract:
1. A method for evaluating a capacity of a cell of a radio access network (RAN), the method comprising: monitoring, by a monitor, (a) downstream traffic that is directed towards the cell and (b) responses from the cell to the downstream traffic, to provide monitoring results; calculating, in response to the monitoring results, round trip time (RTT) statistics; and generating an estimate of the capacity of the cell in response to the RTT statistics wherein the calculating of the RTT statistics comprises calculating connection establishment RTT statistics and calculating established connection RTT statistics; and wherein the generating of the estimate of the capacity of the cell is based on the connection establishment RTT statistics and the established connection RTT statistics; wherein the method comprises increasing the estimate of the capacity of the cell when a bandwidth of the downstream traffic equals the estimate of the capacity of the cell and a current RTT value is below a lower threshold.
