Systems and methods for protocol-based identification of rogue base stations
First Claim
Patent Images
1. A method, comprising:
- 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.

Abstract
A rogue base station detection system that establishes a communication session with a suspected base station, and verifies whether the base station is rogue or innocent by testing which advanced communication features are supported by the base station. The detection system holds a definition of one or more communication features that are supported by innocent base stations and not by rogue base stations. During a communication session with a suspected base station, the detection system requests the base station to activate these communication features. If the base station does not support the features in question, it is likely to be rogue.

10. Apparatus, comprising:
-
a transmitter and a receiver, which are configured to communicate with one or more base stations; and a processor, which is configured to predefine 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, to establish a communication session with a suspected base station, to request the base station, during the communication session, to perform the predefined communication feature, and to classify the suspected base station as innocent or rogue depending on whether the suspected base station performs the requested communication feature, wherein the processor is configured to decide that the suspected base station is rogue in response to detecting that the suspected base station is unable to perform the requested communication feature. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
