The invention relates to methods and systems for
simultaneously updating a plurality of wireless units. In
particular, the invention relates to wireless units contained in
aircraft having complex application software. Periodically, the
software of these wireless units must be updated to reflect more
advanced versions of software. See page 1 of Appellants’
specification. The invention relates to solving the problem for
updating a large number of wireless units in aircraft in an
efficient matter. See page 2 of Appellants’ specification.
The wireless communication systems and methods consistent
with the present invention include a central station, a mobile
unit and a plurality of radio base stations. The central station
receives from the mobile unit registration information
identifying the radio base station currently in communication
with the wireless unit. This registration information is then
stored in a registration database located at the central station.

unit using the radio base station identified by the registration
information stored in the registration database. See page 2 of
