A geographic Hot Zone service for restricting wireless packet data sessions transmitted to/from a restricted geographic Hot Zone created within the coverage area of a wireless packet data communications network is provided. The geographic Hot Zone service is activated to create the Hot Zone during an extraordinary event and reduces the number of packet data sessions in the Hot Zone to only those involving a limited number of authorized Mobile Stations, such as those used by police, firefighters, and other emergency personnel.
