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, the method further comprising managing reference ambient information of surroundings of a terminal device, comprising;
receiving update information of the surroundings of the terminal device;
assessing a reliability of the update information;
changing the reference ambient information of the surroundings of the terminal device when a reliability criterion is fulfilled when assessing the reliability,wherein assessing the reliability of the update information comprises assessing a value of trust of the terminal device, andwherein a value of trust signalizes a high trustworthiness when update information of the terminal device were correct in the past, or wherein the value of trust signalizes a high trustworthiness when an accuracy of the position determination of the terminal device is improved when considering the update information.
