Wherein, terminal can utilize location (position) to obtain function and obtain the current longitude and latitude of terminal, and converts the longitude and latitude of acquisition to metric geodetic coordinates, and this geodetic coordinates is the physical location of terminal.
It should be noted that, second radius is greater than the first radius, first radius is more than or equal to the first preset value, namely the minimum value that the first radius is desirable is the first preset value, second radius is less than or equal to the second preset value, namely the maximum that the second radius is desirable is the second preset value, and the first preset value and the second preset value collectively define the scope at the place, region choosing virtual location.Such as: the first preset value is 1 kilometer, and the first radius can be set to 1.5 kilometers, the second preset value is 10 kilometers, and the second radius can be set to 9.5 kilometers.
1022, with described physical location for the center of circle, described first radius is inner circle radius, and described second radius is in the circle ring area of exradius, and random selecting is a bit as described virtual location of described terminal.
Wherein, taking physical location as the center of circle, first radius is inner circle radius, second radius is in the circle ring area of exradius, during the virtual location of random selecting a bit as terminal, because selected region does not comprise physical location, in this region during chosen position, the position chosen can not overlap with physical location, is namely all virtual location.
In specific implementation process, terminal can utilize location (position) to obtain function and obtain the current longitude and latitude of terminal, and convert the longitude and latitude of acquisition to metric geodetic coordinates, with this geodetic coordinates for the center of circle, with the first radius for inner circle radius, second radius is that exradius forms a circle ring area, and carries out random position in this circle ring area.Such as: as shown in Figure 3 a, the first radius is 1 kilometer, and the second radius is 2 kilometers, and O point is the physical location of terminal, and OA is the first radius, and OB is the second radius.Circle ring area between inner circle and cylindrical is the region of virtual location, and random selecting 1 C is as virtual location in this region.
In addition, the region of virtual location can be circle ring area, can be also the region of similar annular that rectangle is formed, and the shape, size etc. in the region of virtual location are at this and be not construed as limiting.Such as: as shown in Figure 3 b, the region between interior rectangle and outer rectangle is the region of virtual location.
