Description

Method and device for sending terminal position

technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and device for sending terminal position.

Background technique

With the development of wireless positioning technology, indoor positioning technology has become a focus of attention. Where the wireless local area network is covered, the system can track and monitor various assets and personnel at any time, accurately find the target object, and realize real-time positioning and monitoring management of assets and personnel.

At present, the mainstream wireless systems that can support indoor positioning mainly include wireless fidelity (Wireless Fidelity, WiFi), Bluetooth, and base stations. WiFi-based positioning technology has the advantages of wide coverage, fast information transmission, and low implementation cost, and is one of the more commonly used indoor positioning methods. Based on WiFi positioning technology, the positioning calculation only depends on which Wi-Fi access point is closest, rather than on the synthesized signal strength map, which is easy to make mistakes in floor positioning. At present, it is applied to small-scale indoor positioning, and the cost is low. However, whether it is used for indoor or outdoor positioning, Wi-Fi transceivers can only cover an area within a radius of 90 meters, and are easily interfered by other signals, thereby affecting their accuracy, and the energy consumption of the locator is also high. Bluetooth technology is a useful supplement to WiFi positioning technology. Bluetooth technology locates by measuring signal strength. Compared with Wi-Fi triangulation, the efficiency is higher and the cost is lower, and the positioning can be achieved by using ordinary Bluetooth mobile phones. And because of the power saving of Bluetooth, the terminal can work for a longer time. Compared with WiFi and Bluetooth, the technology of base station positioning is generally realized by the method of measuring the arrival time and signal strength of the uplink signal of the terminal by the base station. .

However, the current base station positioning requires the terminal to access the network and then identify its terminal identification to be able to identify the user attributes of the user to be located. If it is applied to indoor positioning, the limitations are relatively large.
