1. A method, in a mobile communication network, of estimating a quality metric for a packet flow associated with an application and carrying latency sensitive content, the method characterized by:
obtaining one or more algorithms for estimating connectivity characteristic variations and the quality metric for the packet flow; and
monitoring network traffic;
classifying packets belonging to the packet flow;
analyzing network traffic parameters for the packets belonging to the packet flow;
based on the obtained algorithm for estimating connectivity characteristic variations, predicting connectivity characteristic variations for the packet flow, including late loss from packet jitter;
based on the obtained quality metric algorithm and the predicted connectivity characteristic variations, predicting a quality metric for the packet flow; and
reporting the predicted quality metric.
