<p>A wireless telecommunication system receives information from a wireless mobile unit associated with a category of information (such as "shopping" for example); and determines that the wireless mobile unit has entered a region including a site associated with the category of information (such as a shopping mall, for example). Information specific to the site and category is then received at a centrally located location-based message server. As the traveler enters the region including the mall, for example, the wireless mobile unit then receives information specific to the site and category such as information relating to sales at the mall. Alternatively, information relating to a category and site received, and all wireless mobile units within a region including the site are then identified so that the received information relating to the category can be output thereto. As such, desired information specific to a region occupied to a traveler is received. <IMAGE></p> |
