If before and after changing, the described signal transmission duration obtained in same position measurement is almost identical so that communication terminal is adopted
When positioning with multiple distance values, the position of location is more consistent every time.
After then server is calculated primary importance and the second position, it is right primary importance and the second position to be carried out
Ratio, if primary importance is consistent with the second position, then the plurality of reference that the primary importance of explanation server memory storage is corresponding
Signal strength values has occurred that change, then server can update the plurality of reference based on multiple signal strength values to be matched
Signal strength values.
Such as, as shown in Figure 10, two data acquiring location (x1, y1) and (x2, y2) for server memory storage are right
The data answered.Multiple RSSI value that (x1, y1) is corresponding include the-92dbm corresponding with AP1, and-the 90dbm corresponding with AP2, with AP3
Corresponding-88dbm and-the 87dbm corresponding with AP4.Then these data can be the reference signal of server memory storage
Intensity level.
And when not changing in indoor building structure or furnishings, communication terminal to be positioned gathers at (x1, y1)
The multiple signal strength values arrived are consistent with shown in Figure 10, thus ensure that server returns to the positional information of communication terminal and is
(x1,y1).But, if being newly provided with a wall or placed other between physical location and the AP1 that (x1, y1) is corresponding
Furnishings, then communication terminal can be caused to obtain AP1 in the physical location detection that (x1, y1) is corresponding and to send the signal strength values of signal
Reduce, cause multiple signal strength values bags that communication terminal to be positioned is uploaded when the physical location location that (x1, y1) is corresponding
Include-the 94dbm corresponding with AP1 ,-the 90dbm corresponding with the AP2 ,-89dbm corresponding with AP3 and the-87dbm corresponding with AP4,
If positioned by these data, then can cause server error allow in the range of by communication terminal location with (x2,
Y2) place, the position being practically in from communication terminal is different.
But, when server is positioned by multiple distance values simultaneously, the position data obtained is still for (x1, y1), service
When device is by (x1, y1) and (x2, y2) comparison, find that both are different, then the reference signal strength value that judgement (x1, y1) place is corresponding need to
Update.

The mark of one property mark AP is uploaded onto the server with signal strength values one piece, is beneficial to server and distinguishes each AP.It is appreciated that
Can be with the MAC Address of AP as mark.Accordingly, updating for the ease of data, server is when gathering data in advance, it is possible to
To gather the mark of each AP for each AP of unique identification.
When the reference signal strength value corresponding to above-mentioned primary importance is updated, server needs first to find first
The first object wireless access points that position is corresponding.The most in Fig. 10, strong to the reference signal that (x1, y1) is corresponding when needs
When angle value is updated, the first object accessing wirelessly that AP1, AP2, AP3 and AP4 of its correspondence is corresponding with (x1, y1) connects
Access point.Described server is searched in described first object wireless access points based on described mark and is mated with described mark
Second Target Wireless access points.Wherein, the reference signal strength value that the second target access access point is corresponding is mated with band
The wireless access points that signal strength values is inconsistent.Server is by reference corresponding for described second Target Wireless access points
Signal strength values replaces with the signal strength values to be matched of correspondence.
Such as, first object wireless access points includes the AP1 that MAC Address is FC-AA-14-67-0F-CA, should
Reference signal strength value corresponding for FC-AA-14-67-0F-CA is-92dbm, and includes MAC ground at signal strength values to be matched
Location is the signal strength values-94dbm corresponding for AP1 of FC-AA-14-67-0F-CA, then corresponding for FC-AA-14-67-0F-CA nothing
Line access points is the second Target Wireless access points.At no point in the update process, server above-mentioned-92dbm can be replaced with-
94dbm.The data-updating method of other the second Target Wireless access points is also such.
