1. A method for a wireless cellular communication system incorporated in a vehicle, comprising:
processing a record having a set of obtained data for a set of intra-cell features associated with a Mobile Station (MS) and a Base Transceiver Station (BTS) of a wireless communication network, the set of intra-cell features being functions of the set of obtained data;
calculating a score for the record based on a machine-learning model pertaining to the set of intra-cell features; and
determining whether the record demonstrates an anomalous condition based upon the score,
wherein the set of intra-cell features is selected from: (1) a ratio between a number of neighboring BTSes reported by the BTS and a maximal number of neighboring BTSes; (2) a ratio between a power of the BTS and a power of a most-powerful BTS of the neighboring BTSes; (3) a variance of a measured power of the BTS within a time window; (4) a ratio between the number of neighboring BTSes reported by the BTS and the power of the BTS; and (5) a ratio of a measured power of a most-powerful BTS of the neighboring BTSes and a next-most-powerful BTS of the neighboring BTSes.
