System and Method for Providing Location Information to a Public Safety Answering Point During an Emergency 911 Call From a WiFi Handset
First Claim
1. A system for providing location information to a public-safety answering point during an emergency 911 call, the system comprising:
- a network access point configured to;
store location information about a physical location associated with a wireless device;
receive an emergency 911 call from the wireless device;
in response to receiving the emergency 911 call, generate a modified caller identification frequency shift keying (CIFSK) signal containing the physical address information of the network access point, wherein generating a modified CIFSK signal comprises;
retrieving the stored location information; and
modifying the CIFSK signal by replacing data in one or more call identification information data fields with the retrieved location information, the physical address information comprising street number and name; and
transmit the generated CIFSK signal to cause a public safety answering point (PSAP) receiving the emergency 911 call to display the physical address.

Abstract
A system and method for providing location information to a public safety answering point may include receiving, at a network access point, an emergency 911 call signal including GPS location information and mobile directory number of a wireless device. The GPS location information and mobile directory information may be communicated to a selective muter associated with a public safety access point servicing an area including the network access point. The network access point may be a WiFi access point. The access point address information may be communicated using a type II caller ID data packet after the public safety answering point goes off-hook By communicating both the access point address information and GPS location information, both PSAPs that are configured as E911 Phase I and E911 Phase II may display address location information of an emergency 911 caller.
