It is responsible for parsing the operation message of the upper layer positioning service application software, and encapsulating the positioning control information into a data packet to be sent to the AP according to the agreed channel, and to other upper layer operation messages (for example) Access to the Internet) Directly transparent to the wireless AP terminal. When the AP has data returned to the PC application software, the parsing location information packet encapsulates the location information for use by the upper application software in a format recognizable by the upper layer software, and other types of data packets are directly transmitted to the upper layer application. The upper layer application communication pipe 102, the upper layer application software communicates with the AP or the external service gateway through a standard communication protocol. The positioning information communication pipeline 103, the upper layer application software and the logical communication channel of the positioning engine interaction, complete the interaction between the positioning configuration operation information and the positioning result information through the agreed data message.

The WLAN data communication module 104, all the data of the STA in the AP must be processed or forwarded by the STA, and when the external network is accessed, it is transmitted through the OTA through NAT conversion, when communicating with other STAs in the AP or performing specific services (such as using a positioning engine) The module needs to be processed, and the positioning operation data packet is processed and forwarded to the positioning engine proxy server 105 according to the specially agreed filter attribute.

Through WLAN communication, the user can enjoy various positioning applications by using the Hotspot product, and the PC driver SDK can be customized or compatible with the standard interface according to requirements. Suitable for all types of needs of operators and value-added service providers. The present invention fills in the gap that Hotspot products cannot provide a complete positioning application. 3 is a flowchart of a positioning method according to a preferred embodiment of the present invention. The positioning method may be implemented based on the Hotspot terminal positioning system shown in FIG. 2. As shown in FIG. 3, the following steps S302 to S332 are included.

If it is not location information (that is, external network data), step S306 is performed. Step S306, the data communicated by the Hotspot terminal and the external network is transparently transmitted to the AP by using the WLAN. Step S308, implementing the corresponding service by OTA forwarding, and ending. In step S310, the SDK driver sends the positioning information group packet to the AP (Hotspot terminal). Step S312, the WLAN data communication module in the Hotspot terminal filters the data packet. Step S314, the WLAN data communication module in the Hotspot terminal determines whether it is a positioning operation data packet, and if it is a positioning operation data packet, proceeds to step S318, otherwise proceeds to step S316. Step S316, discarding the data packet, and ending. Step S318, the WLAN data communication module sends the positioning operation data packet to the positioning engine proxy server, and the positioning engine proxy server parses the positioning information data packet into a positioning instruction recognizable by the positioning engine and sends the positioning instruction to the positioning engine. For multiple positioning instructions of different users, the WLAN data communication module can also sort the positioning instructions and perform access control preprocessing. Step S320, the positioning engine confirms whether the instruction is correct after receiving the positioning instruction, and if yes, performs the step.

S324, otherwise step S322 is performed. Step S322, returning an error message to the PC. Step S324, the positioning engine performs a positioning response according to the instruction, and returns the positioning result to the positioning engine proxy server step S326. The positioning engine proxy server encapsulates the positioning result into an agreed data packet and reports the packet to the SDK driver in the PC through the WLAN communication module. Step S328, the SDK driver parses the positioning result data packet into the positioning information that can be recognized by the upper layer application software. In step S330, the SDK driver reports the location information to the upper layer application. Step S332, the upper layer positioning software performs multiple applications according to the positioning result and the positioning value-added service of the external network. The technical solution adopted by the present invention: design a positioning proxy server and a PC driver SDK for a positioning engine (positioning chip, providing multiple modes of positioning, such as GPS, AGPS, Cell positioning, and Predicted Orbits) in the side of the Hotspot product. The location agent server in the board side is a software module that integrates positioning engine control, positioning information transmission, user access control and WLAN data communication. It combines traditional positioning engine control and positioning information transmission with IP transmission and access control, and encapsulates positioning control commands and positioning information through standard IP packets, compatible with standard or customized positioning data formats, through WLAN links and APs. STA Data communication, with the PC side driver SDK to convert the positioning result information into a standard or custom format for direct use by the upper PC location service software, can be effectively compatible with the existing location location software.
