Method and system for rapid dissemination of public announcements

Abstract

The present invention provides a method and system for disseminating urgent public announcements over an IP-based network. One or a plurality of Internet- or Intranet-connected servers receive and store data identifying particular geographic locations to current announcements. The servers identify IP addresses of users making URL requests or requests for target applications (an access point by which a network-connectable mobile device is connected to an Internet- or Intranet-connected server), determine a location for each user from the user's IP address (or access point), and determine whether an IP address (or access point) of a user corresponds to a location for which an announcement has been posted. If the user is identified to a location for which a current announcement is available, the announcement is displayed to the user.The announcement may be displayed by redirecting the user to a web page containing the announcement. Alternatively, the announcement may be displayed in a pop-up window or in a banner on a web page requested by said user. A banner displaying such an announcement may incorporate a link to permit the user to click through to a web page containing a more detailed version of the announcement.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention generally relates to the dissemination of public announcements and, more particularly, to the rapid dissemination of urgent public announcements using client computers connected to a network, including an Internet Protocol-based network such as the Internet or a private Intranet.[0003]2. Background Description[0004]The Emergency Broadcast System is a well-established means for rapid dissemination of urgent public announcements by interrupting regularly scheduled programming on traditional broadcast communications media such as radio and television. Traditional broadcast communications media are well suited for the rapid dissemination of urgent public announcements because the systems employed by such media are characterized by a large number of user terminals (such as radios or television sets) in a concentrated geographic area, which are configured to receive a continuous stream of a relatively li...

Benefits of technology

[0011]It is therefore an object of the present invention to provide a method and system for rapid dissemination of urgent public announcements to persons who are occupied by accessing the Internet using client-side software such as a browser.

[0017]One approach to implementing the present invention may be employed where an IEAS service controls or has the cooperation of a proxy that provides service for an audience of target users. Such proxies may include Internet service providers, which necessarily control their subscribers' Internet access, and they may also include private Intranets. While Internet service providers and private Intranets may have ready access to users' geographic locations, other possible proxy sites may determine geographic location from users' IP addresses as discussed above. In either case, the geographic location of a user may be cross-referenced to a list of posted local alerts. Having identified a user as being within a geographic location for which an IEAS alert has been posted, the proxy may then redirect a URL request (or a request for a target application) from such a user's browser to a public alert site displaying an urgent public announcement for the user's geographic location. Users whose geographic locations are not associated with a public alert would not have their browsers redirected but would instead access the URL (or target application) as originally requested. Proxies may be implemented in a transparent manner. An Internet service provider may configure the routers, switches or other devices at its points of access so that they redirect all network communications from customers subject to an IEAS site when there is an emergency in the geographic location.

[0024]Various techniques are available for handling the peak load requirements of an IEAS service, including but not limited to the use of a series of distributed sites for IEAS servers and the use of geographic load-balancing techniques. A content delivery network (CDN) service, with appropriate extensions for security, could be employed to enable public alert data to be cached throughout an edge network maintained by the CDN service. Such duplication of content throughout the Internet would facilitate the handling of peak loads and provide users with quicker access than if the data were to reside exclusively on a single server.

[0026]While browsers may appear to be the most suitable means for users to receive an IEAS public alert, other client-side software (including, but not limited to, plug-ins and extensions for browsers) may be used which would allow clients to input or store IEAS alert preferences, to provide more granular geographic location data about a user, or to identify additional geographic locations for which a user wants to receive alerts. Such client-side software applications may include text messaging applications, mobile browsers, or other software running on a mobile Internet-capable device such as a cell phone or personal digital assistant. Such additional client-side software may also permit more effective filtering of alert messages according to their relevance to the user.

[0027]The present invention may also be used within an enterprise computing environment to provide alerts to users of an Intranet. While enterprises may already use Intranets to disseminate some announcements, there is an increasing need for enterprises to limit the dissemination of some announcements to, for example, workers located in a particular facility. Enterprises are increasingly dispersed geographically, and an increasing number of workers are working remotely from their homes or other locations. A conventional audio public address system, while effective for notifying persons within a specific building, cannot reach workers outside the building. Thus, an Intranet-based implementation of the present invention may enable enterprises to disseminate announcements more effectively.

Problems solved by technology

In addition, the continuously streaming nature of radio and television means that program interruptions may have an immediate impact on the information content being displayed by a user terminal.

As radio and television increasingly lose audience to the Internet, communities are experiencing a decline in the number of people who can be reached at any given moment by interrupting regularly scheduled radio or television programming.

Communities are not currently able to disseminate urgent public announcements to persons while they are engaged in operating user terminals to access the Internet, unless there is a radio or television set turned on in the background.

Technical differences between the Internet and conventional broadcast media have made it difficult or impossible to establish an Internet equivalent of the Emergency Broadcast System.
