IDENTIFYING POTENTIALLY MANIPULATED RADIO SIGNALS AND/OR RADIO SIGNAL PARAMETERS BASED ON A FIRST RADIO MAP INFORMATION AND A SECOND RADIO MAP INFORMATION

摘要

A method is disclosed that includes obtaining one or more first radio signal parameters of one or more first radio signals and one or more second radio signals observed by a mobile device at an observation position. The one or more first and second radio signals are radio signals of first and second radio signal types, respectively. The method also includes obtaining first and second radio map information representing first and second radio maps, respectively, for estimating a position of said mobile device based on observable radio signals of the first and second radio signal types, respectively. The method further includes determining first and second position estimates for the observation position of the mobile device at least partially based on the one or more first and second radio signal parameters and the first and second radio map information, respectively. A corresponding apparatus and computer-readable storage medium are also disclosed.
