Protecting location information

摘要

This disclosure provides a method, a Back-end-server (102, 400, 506) and a system (500) for protection of location information of a UE. The Back-end-server can receive (104, 202, 302) a request message from an operator interface (504) requesting location information of the UE. Based on probability criteria or blocking factors, it is determined (110, 208, 306-310) whether location information may be transferred to the operator interface. One advantage is that a quantitative security for the privacy of subscribers is provided, with which the privacy of the subscribers is not disclosed.
