Identifying suspects and witness to shooting based on examination of calls made after shooting

摘要

An illustrative telecommunications analysis server analyzes telecommunications-event records and telecommunications-activity records associated with mobile stations operating in one or more wireless networks to infer whether a spike in initiated telecommunications activities occurred in a period of time and from a geographic area that closely correlate with the time and location of an audio incident. The server corroborates that the audio incident likely occurred based on the inferred spike in initiated telecommunications activities from one or more mobile stations. The illustrative server identifies the mobile stations that were likely within earshot of the incident and actively initiating telecommunications immediately thereafter.

主权项

1. A method comprising:
receiving, by a server, an indication of a location L and an indication of a time T; inferring, by the server, that a spike in initiated telecommunications activities occurred during a period of time P that follows the time T, wherein the spike comprises a first telecommunications activity that was initiated by a first mobile station; and transmitting, based on an estimated location of the first mobile station when the first mobile station initiated the first telecommunications activity, an indication that the first mobile station was located at the time T within a geographic area G that comprises location L.
