IDENTIFYING NEW NETWORK AFFILIATION OF CHURNED SUBSCRIBERS

摘要

A method and an apparatus for identifying the new network affiliation of a churned subscriber. In-network and out-of-network calling behaviours are determined by evaluating call data records during data collection windows occurring before and after a former subscriber of the first network operator has churned. The calling behaviours are correlated to identify a subscriber as a subscriber which has churned and the new network affiliation of the churned subscriber is identified by the external network number.
