Abstract
A wireless telecommunication system receives information from a wireless mobile unit and determines that the wireless mobile unit is within a designated region. Information specific to the designated region is received at a centrally located location-based message server. As the traveler enters the designated region, the wireless mobile unit then receives information specific to the designated region such as information relating to traffic problems or desired locations within the region. Alternatively, a problem is identified and designated as relating to a particular region, and wireless mobile units within the designated region are then identified so that information relating to the problem can be output thereto. As such, information specific to a region occupied to a traveler is received.
