Method and system for deploying disaster alerts in a mobile vehicle communication system
One aspect of the invention provides a method of deploying disaster alerts to a mobile vehicle. The method includes determining disaster area coordinates of a disaster area and calculating buffer coordinates of a buffer region based on the disaster area coordinates. The method further describes a vehicle circle based on a radius of at least one location coordinate of the mobile vehicle and compares the vehicle circle with the buffer region coordinates. The disaster area coordinates are compared with the vehicle circle. The method then deploys at least one disaster alert based on the comparison of the vehicle circle and buffer region coordinates and disaster area coordinates.
