Embodiment 1

[0056] see figure 1 , the embodiment of the present invention provides a three-dimensional indoor positioning method based on big data, such as figure 1 As shown, the method includes steps S1-S4.

[0057] Step S1, collect user plane signaling data information, and analyze the RSSI level signal value of each WIFI sampling point from the user plane signaling data information; according to the RSSI level signal value exceeding the preset level value, they belong to the same floor According to the principle and the analyzed RSSI level signal value, each WIFI sampling point is grouped by floor.

[0058] Signaling data is very important management and monitoring data in the LTE network. When indoor users interact with the LTE network in signaling, some APPs will upload the WIFI network MAC, RSSI and other information detected by the terminal to the LTE network. The actual indoor coverage radius of the existing WIFI AP is about 10-15 meters. No matter whether it is encrypted or not...

Embodiment 2

[0139] In the second aspect, an embodiment of the present invention provides a three-dimensional indoor positioning device based on big data, such as Figure 6 As shown, the device includes:

[0140] The information collection and grouping module 610 is used to collect user plane signaling data information, and analyze the RSSI level signal value of each WIFI sampling point from the user plane signaling data information; according to the RSSI level signal value exceeding the preset Based on the principle that the level values ​​belong to the same floor and the analyzed RSSI level signal value, each WIFI sampling point is grouped by floor; its function is as described in step S1.

[0141] The floor chain building module 620 is used to calculate the correlation between different WIFI sampling points and the correlation between floors according to the difference between the probability value and the level signal value of different WIFI sampling points grouped into the same floor ...

Abstract

The invention provides a three-dimensional indoor positioning method and device based on big data, equipment and a medium. According to the big data-based three-dimensional indoor positioning method,RSSI level signal values of all WIFI sampling points are analyzed from user plane signaling data information, the WIFI sampling points are subjected to floor grouping, and the correlation between thedifferent WIFI sampling points and the correlation between floors are calculated; a WIFI floor chain is obtained according to the correlation between the floors; a low floor is determined according tothe GPS positioning mode proportion of each floor WIFI sampling point; according to the calculated position relation between the low floor and the floors in the WIFI floor chain, the number of the other floors is determined, a floor WIFI fingerprint database is obtained; the WIF sampling point information is compared with the WIFI fingerprint database, and the specific position of each user sampling point is positioned according to a matching result. According to the invention, accurate assessment of building hierarchical network coverage can be realized.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a big data-based three-dimensional indoor positioning method, device, equipment and medium. Background technique [0002] At present, the existing indoor user position stereo positioning scheme: Based on the user's longitude and latitude information, it is associated with the MR wireless network through the IMSI+CELL+TIME method, and the MR sampling points are positioned in the building, which can evaluate the quality of the building network, and the floor-level evaluation requires The user's location is further classified into indoor hierarchical positioning by floors. The existing technology mainly determines the building and floor where the user is located based on the indoor AP location information, and combines the base station information and MR data near the user's resident building to perform indoor hierarchical positioning and indoor coverage evalu...
