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.
