First movement terminal detects the distance between first movement terminal and the second mobile terminal.
In the embodiment of the present application, BLE network quality can be referred to by the Bluetooth received signals intensity of the first movement terminal
Show (Received Signal Strength Indication, RSSI) to determine.For example, the bluetooth of first movement terminal
RSSI is lower than -130dBm, then it is assumed that BLE network is poor.
BLE network quality can also be determined at a distance from the second mobile terminal by first movement terminal.In general,
The distance of the two is closer, and BLE network quality is better；The distance of the two is remoter, and BLE network quality is poorer.
Optionally, first movement terminal detects that the signal quality parameter of BLE network is greater than or equal to preset signals quality
Threshold value, specifically:
First movement terminal detects that the bluetooth RSSI of first movement terminal is greater than or equal to preset signal strength threshold value；
Or,
It is default that first movement terminal detects that the distance between first movement terminal and the second mobile terminal are less than or equal to

Bit, bit rate 125kb/s；If indicating 1 bit, bit rate with 2 symbols using 2 symbolic codings (S2 coding)
For 500kb/s.Obviously, more symbols indicates 1 bit, and the information that the unit time can transmit will be more, but lose
Information also can be more.Above-mentioned " symbol " refers to that the obtained information of unitary sampling, this information may include multiple bits, can also
The multiple information equivalences of energy are in a bit.For example, the first coding mode can be 2 symbolic codings, and the second coding mode can
To be 8 symbolic codings.The corresponding bit rate of 2 symbolic codings is greater than the corresponding bit rate of 8 symbolic codings, and 8 symbolic codings are corresponding
Communication distance be greater than the corresponding communication distance of 2 symbolic codings.If not using physical layer to encode, it is corresponding communication away from
From the corresponding communication distance of 2 symbolic codings is less than, also it is less than the corresponding communication distance of 8 symbolic codings.For example, 8 symbols are compiled
The corresponding communication distance of code is that physical layer is not used to encode 4 times of corresponding communication distance, the corresponding communication distance of 2 symbolic codings
Not use physical layer to encode 2 times of corresponding communication distance.
It should be noted that physical layer can encode, it can not also encode, physical layer does not encode then as common BLE.This
