Locality based alert method and apparatus
Information about emergency situations is securely collected and processed by an agency, such as the local police force. When the information is approved for distribution as an emergency alert of a particular type, the alert is transmitted to a server. The server in turn facilitates the distribution of information widely to the public, and on a locality by locality basis. The server may format the emergency alert message or information for a variety of devices and send the information to those devices to convey the information to the public. The devices may include, for example, wireless devices, such as cell phones, personal digital assistants or any other type of wireless device; computers; electronic road signs; EAS equipment; computers and webpages; and any other type of output device. The server may also act as a web portal to disseminate information to the public and to allow members of the public to sign up to receive emergency alerts in particular localities, for example by zip code, at no cost to government or the public.
1. A method of distributing emergency alerts, comprising:
receiving emergency information describing an emergency, wherein the emergency information is received from an agency, wherein the emergency information is received via a network interface, and wherein the received emergency information has a predetermined format and includes a description of a child, a picture of the child, a description of an abductor, a location identified by an intersection or an address, a time of the abduction, and a description of an automobile;
retrieving a digital certificate from the agency to authenticate the emergency information using the network interface;
identifying a first affected locality using the location identified by an intersection or an address, and a difference between the time of the abduction and a first current time, the first affected locality increasing in size as the difference between the time of the abduction and the first current time increases;
distributing a first emergency alert associated with the received emergency information to a plurality of devices within the first affected locality using a wireless communications network;
identifying a second affected locality using the location identified by an intersection or an address, and a difference between the time of the abduction and a second current time, the second affected locality increasing in size as the difference between the time of the abduction and the second current time increases; and
distributing a second emergency alert associated with the received emergency information to a plurality of devices within the second affected locality using the wireless communications network.
2. The method of claim 1 , further comprising:
translating the received emergency information into different formats associated with a plurality of different user devices, wherein the type of format depends on the type of the user device and the type of the emergency, and wherein the plurality of different user devices are capable of operating in a plurality of different protocols; and
transmitting the formatted emergency information to each of the respective plurality of different user devices.
3. The method of claim 2 , further comprising:
storing information identifying user devices that are associated with alerts in at least one of a plurality of different localities; and
performing the translating and transmitting with respect to each user device.
4. A system for handling emergency alert distribution, comprising:
a user alert database accessible via a network that stores information identifying user devices and at least one of a plurality of different localities, wherein the stored information is received via a network interface;
an emergency information database accessible via the network that stores emergency information, the emergency information being received via a network interface from an agency, and including a plurality of emergency events, each emergency event having a predetermined format and including a description of a child, a picture of the child, a description of an abductor, a location identified by an intersection or an address, a time of the abduction, and a description of an automobile;
a server device coupled to the user alert database and the emergency information database that allows users to access and identify the stored information identifying user devices and at least one of the plurality of different localities and that allows agencies to authenticate the emergency information for distribution as an emergency alert, wherein the users access and identify the stored information via a network interface, and wherein the server device is configured to:
receive emergency information describing an emergency from the emergency information database, wherein the received emergency information has a predetermined format and includes a description of a child, a picture of the child, a description of an abductor, a location identified by an intersection or an address, a time of the abduction, and a description of an automobile;
retrieve a digital certificate from the agency to authenticate the emergency information using the network interface;
identify a first affected locality using the location identified by an intersection or an address, and a difference between the time of the abduction and a first current time, the first affected locality increasing in size as the difference between the time of the abduction and the first current time increases;
distribute a first emergency alert associated with the received emergency information to a plurality of devices within the first affected locality using a wireless communications network;
identify a second affected locality using the location identified by an intersection or an address, and a difference between the time of the abduction, and a second current time, the second affected locality increasing in size as the difference between the time of the abduction and the second current time increases; and
distribute a second emergency alert associated with the received emergency information to a plurality of devices within the second affected locality using the wireless communications network.
5. The system according to claim 4 , wherein the server device further includes software that translates emergency information stored in a predetermined format into a plurality of different formats associated with different devices, and wherein the type of format depends on the type of the user device and the type of the emergency.
6. The system according to claim 5 , wherein one format of the plurality of different formats includes an EAS system format.
7. The system according to claim 5 , wherein one format of the plurality of different formats includes at least one format associated with an electronic traffic sign.
8. The system according to claim 5 , wherein one format of the plurality of different formats includes a web page format associated with an uniform resource locator for an emergency corresponding to the emergency information.
9. The system according to claim 5 , wherein one format of the plurality of different formats includes an electronic mail format for an emergency corresponding to the emergency information.
10. The system according to claim 5 , wherein one format of the plurality of different formats includes at least one wireless device format for an emergency corresponding to the emergency information.
11. The system according to claim 10 , wherein the at least one wireless device includes a mobile telephone.
