Yes, Google is no longer available. Base station positioning on Baidu apistore, apix, aggregate data and other platforms should all be charged, and it is difficult to find free ones! And it’s not necessarily good either. It should be relatively simple to use, such as https://www.juhe.cn/docs/api/... on aggregated data. You need to register first, and then apply for a key to call. If not, All the paid platforms have customer service.
To determine the longitude and latitude position of the base station through the cdma base station code, you must know the three base station data of Sid, Nid, and Bid, each of which is indispensable. SID is the system identification code. Each prefecture-level city has only one SID, which is unique. NID is a network identification code, which is managed by each local network, that is, assigned by prefecture-level branches. Each prefecture-level city may have 1 to 3 nids.
