S303, to obtain each data according to the time difference that sends lead data bag and receive reply data bag logicalThe link quality measurements result in road.
Lead data bag does not carry any user data. The effect that sends lead data bag is to measure current chainRoad quality. Lead data bag can be the self-defined test packet of ping bag or similar ping bag. This fromDefinition test packet does not comprise user data, only for link quality measurements.
After lead data bag sends, the reply data bag (ACK) that terminal wait network returns, by sending outThe time delay of sending and receive can be determined chain-circuit time delay and the congestion situation of current data passage.
In addition,, in order to ensure the accuracy of measuring, also can be in the following manner two carry out link quality measurements:
S311, send continuously multiple lead data bags by the data channel of opening respectively;
S312, the multiple reply data bags that return by the data channel reception network of opening;
S313, calculate by each data channel and send multiple lead data bags and receive multiple replying respectivelyThe average of the time difference of packet;
S314, will calculate gained average as the link quality measurements result of each data channel.
Which, by calculating the average of link quality measurements result of each data channel, can be more accurateThe measurement that realizes link-quality.
Aforesaid way one and mode two can realize the reality to link-quality by the mode that sends lead data bagIn time, measures, and can obtain the measurement result of the link-quality such as chain-circuit time delay, congestion ratio.
In addition, also can pass-through mode three, based on parameter preset, link-quality is measured. Concrete, pre-Setting parameter can comprise: signal strength signal intensity (RSSI), signal to noise ratio (SNR), Reference Signal Received Power (RSRR),Bandwidth, packet loss etc. While adopting this kind of measuring method, preset according to the above-mentioned of each data channel of obtainingParameter value obtains the link quality measurements result of each data channel.
