1. A method for localizing terminal devices, comprising:
- determining ambient information by means of the terminal device;
determining a position of the terminal device based on the ambient information;
determining a deviation of the ambient information from reference ambient information allocated with the position of the terminal device; and
undertaking an updating measure when a deviation is determined.

Abstract
When localizing terminal devices an updating measure of reference ambient information allocated to surroundings of the terminal device is executed when a deviation of ambient information determined by means of the terminal device from reference ambient information allocated to a position of the terminal device is detected.
