Method and system for realizing terminal positioning by using air base station

Abstract

The invention provides a method and a system for realizing terminal positioning by using an air base station, and relates to the field of positioning technologies and air base stations. A positioning technology based on a satellite system has the problem of weak positioning signals and needs a special positioning chip, while a positioning technology based on a ground base station system has relatively large limitation in the actual application as signals of a base station and a terminal are generally refracted and reflected in an actual environment and the parameter measurement precision is difficult to guarantee. Along with a possibly generated air base station communication network architecture, the air base station is used as a positioning signal reference source as a new positioning system mode, and the possibility is provided for improving the positioning precision of the terminal in a low-cost mode. Since the positioning signal diameter channel probability between the terminal and the air base station is improved, the parameter measurement accuracy of the positioning signal is improved, and meanwhile, the air base station exchanges measurement parameters through position adjustment and communication with the terminal, so that the improvement of the positioning precision is facilitated.

Description

technical field [0001] The invention relates to the fields of terminal positioning and air base stations, and in particular to a method and a system for a communication terminal to use the transmission signal of the air base station or an air base station to realize terminal positioning by using the transmission signal of the communication terminal. Background technique [0002] Location Based Services (LBS, Location Based Services), also known as location services, is a location-related service provided by wireless operators for users. The location-based service enables the operating company to add a new value-added service that is popular with users, adding new revenue. The mobile communication system obtains the geographic location information (such as longitude and latitude coordinates) of the mobile terminal through a specific positioning technology, and provides it to the mobile user himself, the communication system or a third-party positioning client, and with the su...

Problems solved by technology

[0031] Disadvantages: specific module support is required (general mobile phones now have GPS modules), the first positioning is slow, it is almost impossible to use indoors, and it consumes more power to turn on GPS

[0047] Positioning algorithms based on positioning reference signal time measurement / angle measurement are also applied in base station systems, but in the actual land communication network environment, since the communication path between the terminal and the base station is often blocked by buildings, the signals of the base station and the terminal are usually It will go through refraction and reflection, so the accuracy of its measurement parameters is difficult to guarantee, and there are limitations in practical applications
