  • predefining at least one communication feature that, when supported by a base station indicates that the base station is innocent and when not supported by the base station indicates that the base station is suspected of being rogue;

    establishing a communication session with a suspected base station;

    during the communication session, requesting the base station to perform the predefined communication feature; and

    classifying the suspected base station as innocent or rogue depending on whether the suspected base station performs the requested communication feature, wherein classifying the suspected base station comprises deciding that the suspected base station is rogue in response to detecting that the suspected base station is unable to perform the requested communication feature.
