Location-based broadcast messaging to mobile devices located in or entering into a defined geographic area

Abstract

For a location-based broadcast messaging service, a broadcast server receives a broadcast request from a business application server. The broadcast request includes a message, at least one identifier for target mobile devices, and an identifier for a location. The broadcast server sends a location query including the identifier for the location to location agents associated with the target mobile devices. In response to receiving the location query, each location agent determines whether the location of the associated mobile device is within or otherwise satisfies a requirement related to the identified location. If the location of the device is within the identified location or satisfies the requirement, the location agent sends a query response to the broadcast server and receives, from the broadcast server, the message included in the broadcast request. The broadcast request can include a time-period identifier, such that the location agent determines the device location during the time-period.
