Digital content distribution system for delivering location specific content to an ad hoc group of mobile subscribers

摘要

A digital content distribution system and method are disclosed for delivering location specific content to an ad hoc group of mobile subscribers. The system consists of a downloadable application that runs on the subscribers mobile communication device and communicates with a server-based content composer system. The content composer system manages outgoing content based upon the geographic location reported by a mobile communication device application and the demographic and preference data stored in a subscriber database. Emergency alerts are sent only to subscribers in a area covered by the alert. The emergency alerts are executed on the mobile communication device even though the mobile communication device is in a low power sleep or hibernate mode. Moreover, the emergency alerts take over the mobile communications device no matter what other tasks are being executed when the emergency alert is received.
