Calculate, obtain belonging to the set of terminal of the same area.
First, by taking A and B as an example, the distance between A and B D is calculated by formula, formula is as follows：
D=R*Arccos (C) * ∏/180,
C=sin(MLatA)*sin(MLatB)*cos(MLonA-MLonB)+cos(MLatA)*cos(MLatB)。
Wherein, R is earth radius, and LonA and LatA is respectively the longitude and latitude of terminal A, and LatB and LonB is respectively eventually
The longitude and latitude of end B, MLatA, MLatB, MLonA and MLonB are the value after longitude and latitude process, specifically, if
On the basis of 0 degree of warp, then can just calculate the surface distance of point-to-point transmission according to the longitude and latitude of earth surface any two points
（Here the error that earth surface landform is brought to calculating is ignored, only theoretic estimated value）.If the longitude and latitude of terminal A is
(LonA, LatA), the longitude and latitude of terminal B is (LonB, LatB), according to the benchmark of 0 degree of warp, east longitude degree of learning from else's experience on the occasion of
(Longitude), west longitude degree of learning from else's experience negative value (- Longitude), north latitude takes 90- latitude values (90-Latitude), and south latitude takes 90+
Latitude value (90+Latitude), then two after above-mentioned process point be counted as (MLonA, MLatA) and (MLonB,
MLatB)。
R with D units are identical, if using 6371.004 kms as radius, then it is unit that D is exactly km, is passed through
Formula is calculated, and finds the first threshold of the distance between A and B less than setting, such as 10 meters, it is possible to determine that A and B is to be in close on
Position.Equally, the distance of A and C, the distance of B and C is again smaller than threshold value, it is possible to determine that A, B and C are in adjacent locations.Continue to calculate
After the distance of E and A, B and C, find E with（A or B or C）Distance more than the threshold value of setting, judge that E and A, B, C are not closing on position
Put.Therefore, A, B and C constitute a set of terminal.
After second location updating, as shown in following table two：
Table two
| Termination ID | Longitude | Latitude | Timestamp |
| A | 39.860012 | 116.425625 | 20130831170010 |
| B | 39.860023 | 116.425630 | 20130831170010 |
| C | 39.860033 | 116.425644 | 20130831170010 |
| E | 38.111 | 110.122 | 20130831170010 |
In order to reduce amount of calculation, the side-play amount of A, B and C can be calculated, calculate A, B and C side-play amount by way of come
Whether the position relationship for judging each terminal changes.Side-play amount calculating is carried out to 2 latitude and longitude coordinates of A terminals, longitude is found
Skew 0, latitudinal offset 0.000005.Same calculating finds that the longitude and latitude side-play amount of B, C is identical with A, it is possible to determine that A, B and C after
It is continuous to be in adjacent locations.It is thus identified that A, B and C belong to same set of terminal, can trigger once collaboration and play.
