Abstract
A network of interconnected, remotely distributed, location and messaging systems. Each of the remotely distributed location and messaging systems can be dynamically configured to use different frequencies that are assigned to the regions. Each of the remotely distributed location and messaging systems performs location requests for specified subscriber unit using one or more radio frequency transmitting sites and a plurality of radio frequency receiving sites. The location request is initiated by identifying a particular one of the location and messaging systems having a coverage area for the specified subscriber unit. The location request is routed to the identified location and messaging systems, and a unique paging message is transmitted to the subscriber unit. A response is received from the subscriber unit, and forwarded to a processor coupled to the identified location and messaging system. The processor resolves the response from the subscriber unit into a location for the subscriber unit within the coverage area of the identified location and messaging system.
