Abstract
A location of a mobile phone in a cellular network is determined when the mobile phone has been turned off, placed in airplane mode, inactive mode or in idle mode. A first cell of interest and times of interest is received, and a location determination server in communication with the cellular network requests call data records (CDRs) associated with the first cell of interest and the times of interest. The location determination server receives the requested CDRs and determines possible locations of the mobile phone at the times of interest when the mobile phone antenna is powered off, airplane mode, idle or inactive using the received CDRs.
