ABSTRACT:
SMS based alert messages are routed to subscribers via a Mobile Switching Center (MSC) such that SMS alert messages can be provided to specific cell sites. Also, SMS alert message can be provided to all subscribers registered in a specific cell site, including roamers. When an MSC receives one alert message, it routes that one message to all subscribers known to the MSC. In an example embodiment, an emergency alert message along with an indication of the alert area is received by an emergency alert server. MSCs capable of facilitating cellular coverage for the alert area are determined. Cell ID (cell sites) associated with the MSC are determined, and the alert message is routed to subscribers currently registered in the cell ID.
