A system, method, and computer program product are provided for detecting duplicated telecommunications events in a consumer telecommunications network. In use, a first telecommunications event and associated first event data are received. One or more fields of data are extracted from the first event data. Additionally, a single data string is generated from the extracted one or more fields of data. Further, a hash function is utilized to create a first event signature corresponding to the single data string from the extracted one or more fields of data. In addition, a first event signature hint is extracted from the first event signature, the first event signature hint including a portion of the first event signature. Furthermore, it is determined whether the first event signature hint exists in a signature hint hash table. Responsive to determining that the first event signature hint does not exist in the signature hint hash table, the first event signature hint is stored in the signature hint hash table and the first event data associated with the first telecommunications event is stored in a telecommunications event storage. Additionally, responsive to determining that the first event signature hint exists in the signature hint hash table, it is determined whether the first telecommunications event is identical to a previously received second telecommunications event stored in the telecommunications event storage. Moreover, responsive to determining that the first telecommunications event is identical to the previously received second telecommunications event stored in the telecommunications event storage, the first telecommunications event and the second telecommunications event are designated as a duplicate event.
