Abstract

A navigation system integrated with knowledge of active emergency alerting system alert data and up to date Doppler weather radar data, to provide a visual representation of an alert area and/or current weather patterns on a map, and to automatically navigate a subscriber device away from an affected area, e.g., an alert area, an area under severe weather. The inventive navigation system displays NEXRAD Doppler weather radar data on a map by integrating a NEXRAD feed into the map and allowing a user to enable/disable the NEXRAD feed as a map overlay. The inventive navigation system also automatically routes or reroutes a subscriber device to avoid areas under severe weather. The navigation system is also integrated with a conventional CMSP gateway in an emergency alerting system to provide: a visual representation of an alert area on a map and to automatically route/reroute a subscriber device around an alert area.

Claims

1. A navigation system, comprising:

a commercial mobile service provider (CMSP) gateway in an emergency alerting system, said CMSP gateway including;

a plurality of active emergency alerting system alerts, and

a plurality of weather radar data; and

a display adapted to display a visual representation of an active one of said plurality of active emergency alerting system alerts and at least one of said plurality of weather radar data.

2. The navigation system according to claim 1, wherein:

said display includes a visual representation depicting respective coverage areas emitted by a plurality of cell sites located in an active alert area.

3. The navigation system according to claim 1, wherein:

said display further displays current weather patterns on a map.

4. The navigation system according to claim 1, wherein:

said navigation system includes a user option to pan and zoom said display to a view weather pattern in another area.

5. A method for performing navigation redirect around an active alert area, comprising:

receiving alert information from a commercial mobile service provider (CMSP) gateway in an emergency alerting system;

instructing a session manager device to update an alert database with said alert information;

determining that an alert area defined in said alert information intersects an active navigation session;

instructing a navigation engine to reroute said active navigation session to avoid said alert area;

returning updated route information to said session manager; and

updating said active navigation session with said route information on a navigating subscriber device.

6. The method for performing navigation redirect around an active alert area according to claim 5, wherein said alert information comprises:

an alert type;

an alert expiration;

a recommended action; and

an alert area.
