Abstract: Methods and systems for determining the identity of a genuine Base Station (BS) that serves a rogue BS, i.e., the genuine BS used by the rogue BS to exchange the communication between the solicited terminal and the cellular network. The ability to identify rogue-serving BSs is a valuable tool in combatting rogue BSs. For example, the rogue BS will often be located in close proximity to the rogue-serving BS, at least in closer proximity than other genuine BSs. Identifying the rogue-serving BS may therefore assist in locating the rogue BS. Additionally or alternatively, identifying the rogue-serving BS may assist in interfering with the operation of the rogue BS, and/or obtaining information regarding wireless terminals solicited by the rogue BS.

Abstract: Methods and systems for monitoring communication of mobile communication terminals, such as cellular phones. An off-air monitoring system reconstructs both directions of a call conducted between two mobile terminals by receiving only downlink channels. The off-air monitoring system receives multiple downlink transmissions transmitted by base stations in a wireless communication network. The system uses the received downlink transmissions to reconstruct the bidirectional call content of calls conducted between wireless terminals. In order to reconstruct the bidirectional content of a given call, the system identifies and correlates the two downlink transmissions of that call from among the multiple received downlink transmissions.

Abstract: Methods and systems for decoding monitored communication signals using previously identified side information. Information, which is used for decoding a given frame and is provided to the decoder not via the main communication channel between a base station and a mobile station, is referred to herein as “side information.” The side information can also be viewed as extrinsic information that was derived during previous decoding operations. The monitoring system holds, for certain frames, a-priori information of one or more data values that are expected in these frames. Decoding using this a-priori information enables an Error Correcting Code decoder to successfully decode such frames, which would otherwise fail to decode.
