Embodiment Construction
[0066] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0067] Figure 4 It is a schematic diagram of area division of positioning space in a specific embodiment of the present invention. As shown in the figure, the present invention is applicable to the positioning space covered by the WiFi network. Several APs are arbitrarily deployed in the positioning space, and the positioning space is divided into several positioning areas (ValueO, Valuel...), and the mobile terminal is located in each positioning space. Several APs can be detected in the area and AP information can be collected, including AP unique ID (MAC address), signal strength (RSS), etc. The AP information that the mobile terminal can detect and collect in the positioning area ValueO is shown in Table 1:
