Background
In the communication network data, in order to perform real-time positioning on a user, MR (user equipment measurement report, hereinafter abbreviated as MR) data and core network XDR data can be correlated, and data with longitude and latitude position information (hereinafter abbreviated as AGPS data) in the MR data is used for assisting in user positioning, since most users do not turn on the GPS function for a long time, the AGPS data only accounts for about 3% -5% of the whole MR data, and in order to improve the positioning proportion, the AGPS data needs to be used for backfilling the longitude and latitude position information of the MR data without reporting the longitude and latitude position information.
