Abstract
A method and device for identifying degradation in service quality for a wireless media service. The wireless media service has a known expected packet generation rate, which may be determined by the device based upon the codec and payload size selected on initiating the media service. At a receiving device, the packets actually received by the device from the other termination point are counted over a time period, and this number is compared with the number of packets that were expected based upon the known packet generation rate. From this comparison a packet loss rate may be determined. If the packet loss rate exceeds a threshold level, then the device may issue a user alert, terminate the service, or take other action. The threshold level may be established based upon a packet loss rate corresponding to a significant degree of service quality degradation.
