Abstract:
1. A packet loss processing method, wherein the method is applied in a mobile transmission network, and the method comprises: receiving, by a destination network node device, data sent through at least two transmission quality measurement protocol links by a source network node device, wherein service priorities of the at least two transmission quality measurement protocol links are different; and determining a reason for occurrence of packet loss according to packet loss ratios on the at least two transmission quality measurement protocol links and the service priorities of the at least two transmission quality measurement protocol links when the destination network node device detects that the packet loss occurs on the at least two transmission quality measurement protocol links, wherein the source network node device is a base station or a base station controller and the destination network node device is a base station or a base station controller; wherein determining the reason for the occurrence of the racket loss comprises: determining, by the destination network node device, whether the packet loss ratios on the at least two transmission quality measurement protocol links and the service priorities of the at least two transmission quality measurement protocol links are in an inverse proportion relationship; determining that the packet loss is caused by network congestion if in the inverse proportion relationship; and if not in the inverse proportion relationship, determining, by the destination network node device, whether the packet loss ratios on the at least two transmission quality measurement protocol links are approximately equivalent, and determining that the packet loss is caused by a bit error if the packet loss ratios on the at least two transmission quality measurement protocol links are approximately equivalent; and if the packet loss ratios on the at least two transmission quality measurement protocol links are not approximately equivalent, determining that the packet loss is simultaneously caused by network congestion and the bit error.
