Abstract
A method and apparatus for deriving indoor/outdoor classification information for call data for a wireless communication network. The method comprises identifying a set of subscriber call data records relating to vehicular calls, deriving a physical channel measurement threshold value based at least partly on physical channel measurement values for the subscriber call data records identified as relating to vehicular calls, and classifying subscriber call data records for the wireless communication network as indoor subscriber call data records and outdoor subscriber call data records based at least partly on a comparison of physical channel measurement values for the subscriber call data records with the derived physical channel measurement threshold value.
