9. A positioning apparatus for a roaming user, the apparatus comprising:
a receiving processing module, configured to receive an XDR signaling, where the XDR signaling includes user information and serving cell identifier information;
the judging and processing module is used for judging whether the user corresponding to the user information is a roaming user;
a first determining module, configured to determine location information of the user based on the serving cell identifier information and a corresponding relationship between preset serving cell identifier information and location information if the user is a roaming user.
10. The method of claim 9, wherein the user information is an MDN number,
the judgment processing module is specifically configured to:
extracting an HLR identification code from the MDN number;
comparing the HLR identification code with a preset local HLR identification code;
and judging whether the user is a roaming user or not according to the comparison result.
11. The apparatus of claim 9, further comprising:
a first calibration module for calibrating the position information of the user using the MR data of the user.
12. The apparatus of claim 9, further comprising:
the analysis processing module is used for analyzing the longitude and latitude information of the user from the XDR signaling based on an OTT positioning algorithm;
and the second calibration module is used for calibrating the position information of the user by utilizing the longitude and latitude information of the user.
13. The apparatus of claim 9, wherein the XDR signaling further comprises traffic usage by the user,
the device further comprises:
a second determining module, configured to determine a traffic usage amount of the user in an attribution scenario of the serving cell.
14. A positioning device for a roaming user, the device comprising:
a memory for storing a program;
a processor for executing the program stored in the memory to perform the method for locating a roaming user as claimed in any one of claims 1 to 8.
