Abstract: A Mobile Alert Network service includes identifying an Alert Area related to an Event Location, identifying a group of subscribers in the Alert Area, and broadcasting an Alert Message to the identified subscribers in a push-to-talk-equivalent environment. The Alert Messages can alert the subscribers about the cause of the alert, offer message related choices, and offer event related choices, such as promotion information or offers. The MAN Service may include an Alert Information Service, a Subscriber Selector, and a Broadcast Module to generate an Alert Message. The event related choices may be generated based on campaigns by Promotional Agents. A wrapper can be downloaded to manage Alert Messages, a mailbox, and to update on board applications. A on-board logger can provide a detailed account of the operations of the handset and its user. A Sensor Array can be used to determine the location of users, based on the self-identification information, broadcast by the cell phones.
