A cell phone system that controls the functionality of cell phones based
upon their geographical locations. Functionality information stored in
data bases located at and unique to each location. A local or low power
transmitter at each location transmits functionality information from the
data bases to cell phones currently at the locations. Alternatively, a
single data base common to the entire network is used to store
functionality information for a plurality of locations. The geographical
location of active cell phones is monitored and when a cell phone enters
a restricted location, cell phone location information is transmitted to
the network data base to read it out and transmit the applicable
functionality information to cell phones. The functionality information
may represent voluntary restrictions displayed on the cell phones or they
may be mandatory restrictions that inhibit cell phone functions defined
by the restrictions.
