Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for sending a terminal position.
Background
With the development of wireless positioning technology, indoor positioning technology becomes a focus of attention. In the place covering the wireless local area network, the system can track and monitor various assets and personnel at any time, accurately find a target object and realize real-time positioning and monitoring management of the assets and the personnel.
Currently, the mainstream wireless systems capable of supporting indoor positioning mainly include wireless fidelity (WiFi), bluetooth, a base station, and the like. The positioning technology based on WiFi has the advantages of wide coverage range, high information transmission speed, low implementation cost and the like, and is one of the indoor positioning means which are commonly used at present. The measurement and calculation of the positioning based on the positioning technology of the WiFi only depends on which Wi-Fi access point is nearest, and does not depend on a synthesized signal strength diagram, so that errors are easy to occur in floor positioning. At present, the method is applied to indoor positioning in a small range and is low in cost. However, whether the Wi-Fi transceiver is used for indoor or outdoor positioning, the Wi-Fi transceiver can only cover an area with a radius within 90 meters, and the Wi-Fi transceiver is easily interfered by other signals, so that the accuracy of the Wi-Fi transceiver is influenced, and the energy consumption of the locator is high. Bluetooth technology is a beneficial addition to WiFi positioning technology. Bluetooth technology locates by measuring signal strength. Compared with Wi-Fi triangulation, the method has higher efficiency and lower cost, and can realize positioning by using a common Bluetooth mobile phone. And because of the electricity-saving property of the Bluetooth, the working time of the terminal can be longer. Compared with WiFi and Bluetooth, the base station positioning technology is generally realized by adopting a method of measuring the arrival time and the signal strength of an uplink signal of a terminal by a base station, and is different from the two positioning means, and the base station positioning is a method for positioning the terminal by a network and does not need the intervention of the terminal.
However, the current base station positioning needs the terminal to identify the terminal identifier after accessing the network, and then the user attribute of the positioned user can be resolved, and if the method is applied to indoor positioning, the limitation is large.
