Method and apparatus for deriving indoor/outdoor classification information

摘要

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.

主权项

1. A method comprising:
identifying, by a device, a set of subscriber call data records relating to vehicular calls; deriving, by the device, a physical channel measurement threshold value based on physical channel measurement values for the identified set of subscriber call data records,
deriving the physical channel measurement threshold value including:
determining whether a particular quantity of the physical channel measurement values is available;deriving, when the particular quantity of physical channel measurement values is not available, the physical channel measurement threshold value based on a theoretical physical channel measurement value; andderiving, when the particular quantity of physical channel measurement values is available, the physical channel measurement threshold value based on mean and standard deviation values for the physical channel measurement values; and classifying, by the device, subscriber call data records for a wireless communication network as indoor subscriber call data records or outdoor subscriber call data records based on a comparison of physical channel measurement values and the derived physical channel measurement threshold value.
