FIG. 7 is a schematic diagram of a cell set learning process according to a preferred embodiment of the present invention. As shown in FIG. 7, the flowchart includes the following steps: Step S702: A terminal STA successfully connects to a hotspot AP, obtains a network address, and sends a terminal STA to obtain The cell set message is sent to the AP. Step S704: After receiving the message, the AP queries whether it stores the cell set, and if yes, returns the cell set information message, otherwise returns a failure message. If the terminal STA receives the AP return cell set information message, the terminal performs Step 714: Step S706: If the terminal STA receives the AP return failure message, the terminal STA obtains the cell set message from the server Service, and the server returns the cell set information or the failure message. Step S708: If the terminal STA receives the server service failure message, the terminal STA Obtaining location information of the MNC, the MCC, the LAC, the CID, the cellular network signal strength value CellRSSI, and the AP signal strength value ApRSSI of the current hotspot AP; Step S710: Comparing whether the MNC, the MCC, the LAC, and the CID in the current location information are stored with the terminal STA The cell sets are exactly the same. If they are not identical, they are inserted directly into the cell set stored by the STA. The position information; if there is a comparison AP signal strength value ApRSSI size, the newly acquired ApRSSIn is greater than the existing ApRSSIm, the record is updated; Step S712, if the acquired ApRSSIn is smaller than the existing ApRSSIm, the discarded just acquired In step S714, if the terminal STA receives the cell set information sent by the network side, the terminal STA should first merge the cell set Collection_m corresponding to the original AP with the acquired cell set Collection_n, and FIG. 8 is preferred according to the present invention. A schematic diagram of the cell set data structure of the embodiment, as shown in FIG. 8, if the same cell (MNC, MCC, LAC, and CID are the same), the cell with the large ApRSSI is saved; then the terminal STA obtains the current carrier attribute (MNC). , MCC), LAC, CID, cellular network strength value CellRSSI, AP signal strength value ApRSSI and other location information, whether the newly acquired MNC, MCC, LAC, CID is already in the cell set stored by the terminal STA, if not, Then directly save the piece of position information to the terminal STA cell set; then compare the AP signal strength value ApRSSI size, just acquired the ApRSSIn large Existing ApRSSIm, then the record is updated, if less than the existing ApRSSIm, just acquired position information is discarded. Step S716: After the terminal STA finishes saving or updating the current location information, the AP sends the location information to the server service through the AP; the AP or the server service receives the cell set information sent by the terminal STA, and the AP or the server service will own the cell corresponding to the AP.

Step S904, the terminal STA queries the stored cell set, and compares whether the current cell exists in the cell set, that is, the MNC, the MCC, the LAC, and the CID are the same. If there is the same cell, go to the next step. Otherwise, the process ends; in step S906, the terminal STA checks whether the user sets the cellular signal CellRSSI to participate in the positioning, and if so, goes to the next step; otherwise, the terminal STA turns on the WLAN, and scans to the hotspot AP corresponding to the cell and automatically connects; Step S908, the terminal STA checks whether the currently acquired cellular signal CellRSSIg is in the range of CellRSSIk A RSSI, where CellRSSIk is a cellular signal value corresponding to the cell stored by the terminal, and A RSSI is a signal fluctuation range set by the user; if CellRSSIg is in the range Then, the terminal STA automatically opens the WLAN, and automatically connects to the hotspot AP corresponding to the cell, otherwise the process ends.
