Abstract
A method is disclosed that includes obtaining one or more radio signal parameters of one or more radio signals observed by a mobile device at an observation position. The method also includes obtaining or holding available radio map information representing a radio map of a predetermined environment. The radio map is indicative of an expected radio environment of the predetermined environment. The method further includes determining, at least partially based on the one or more radio signal parameters and the radio map information, whether the one or more radio signal parameters are expected or unexpected. A corresponding apparatus and a computer-readable storage medium are also disclosed.
