The automatic base station data updating method comprises the following steps of: collecting base station positioning request information with a positioning failure or a great positioning error sent by a user to serve as complementarily acquired base station data; sending the collected data to a data switch server in real time by using a base station positioning server; when the complementarily acquired data reaches a certain amount, starting a data compilation function automatically by using the data switch server to generate latest base station data; after generating the latest base station data, sending base station data updating broadcast to a base station positioning server group by using the data switch server; and sending a base station data updating request to the data switch server and acquiring updated base station data by using the positioning server. The method has the advantages that: by automatically acquiring base station data information according to a positioning request sent by the user, the cost for statically acquiring the base station data information actively is greatly saved, and simultaneously the capacity of updating the base station positioning data in real time of a positioning system is enhanced.
Description
Technical field
The present invention relates to the wireless location technology field, particularly relate to a kind of automatic renewal base station data method.
Background technology
Along with location technology constantly develops, be subjected in recent years paying close attention to widely, mobile positioning technique not only can all be widely used in Criminal Investigation, vehicle management, navigation and intelligent transportation system many-sides such as (ITS), can also be for each operator constantly release new business satisfying the growing demand of user, thus drive further developing of China's mobile communications industry.
On positioning accuracy, GPS positioning accuracy height, and the poorest based on the location of base station; But there are some shortcomings in GPS location, as, guarantee receiving satellite signal, have under the situation that high building stops in indoor and urban district, signal receives problem, thus the application of restriction GPS location; The time of GPS cold start-up is longer, and the real-time of location is not being met; GPS module power consumption is big, and increases hardware cost.All situation analysis, base station are positioned at this aspect and have certain advantage, the mode that adopts base station information to position will be after an important directions of location technology.
Thus, at collection, analysis and the application of radio communication base station information, will be a complexity and important techniques work.We find that in the position application of base station base station data can often dynamically switch and constantly build new base station problem.The base station data collecting work just adopts static the collection if this just makes us, and the method for fixed base stations locator data can't satisfy positioning requirements.
Summary of the invention
In order to address the above problem, the present invention proposes a kind of automatic renewal base station data method, and the technical solution adopted in the present invention is: a kind of automatic renewal base station data method may further comprise the steps:
