Patent ID: 8290470

Claim:
A system for providing location information to a public-safety answering point during an Emergency 911 call, said system comprising: a WiFi access point configured to: store WiFi access point physical address information; in response to receiving an emergency call from a WiFi enabled wireless device, generate a modified caller identification frequency shift keying (CIFSK) signal containing said physical address information of the Wifi access point, wherein said generating comprises: retrieving the stored physical address information; and modifying the CIFSK signal by replacing data in the call identification information data fields with the retrieved physical address information, said physical address information comprising street number and name; and transmit the generated CIFSK signal to a controller; the controller in communication with said WiFi access point and configured to: receive information associated with the WiFi enabled wireless device from said WiFi access point in said CIFSK signal; and communicate an identifier of the WiFi enabled wireless device and WiFi access point identification information, and the WiFi access point physical address information to a gateway; a database in communication with said controller, said database including network address information of selective routers through which information is communicated to public safety answering points, and configured to: identify, in response to receiving a selective router request, a selective router; and communicate selective router information of the identified selective router in response to the request; and a gateway in communication with said database and in communication with a network on which the selective routers are operating, said controller being configured to request selective router information, from said database, of a selective router through which information is to be sent to a public safety answering point servicing an area including said WiFi access point during an emergency 911 call by communicating the WiFi access point identification information to said database; said gateway further being configured to receive the selective router information and communicate the emergency 911 call including the WiFi access point physical address to the selective router identified by said database, to cause the public safety answering point receiving the emergency 911 call to display the physical address.
