Method and system for identifying degradation of a media service by determining a packet loss rate

摘要

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 (62), which may be determined by the device (10) based upon the codec and payload size selected on initiating the media service. At a receiving device (10), the packets actually received by the device (10) 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 (62). 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.
