A location visit detail service, typically provided by a wireless carrier
to a subscriber, includes a portable wireless device, a location
identification means and a central processor. The central processor
periodically receives location data generated by the location
identification means. The central processor data transforms the location
data into time and position data pairs that identify the location of the
portable wireless device at a particular time. Through a geographic
information system database, the position data is converted to street
address data. The details data is provided by the wireless carrier to the
subscriber, which can use the details data to provide a summary report
describing the activity of the service person. This summary report can be
used for preparation of bills or for gathering statistics on (individual
or group) service person efficiency. Alternatively, the wireless carrier
can prepare the report that is then transmitted to the subscriber.
