Systems and methods for supporting E911 emergency services in a data communications network
First Claim
1. A method of supporting enhanced 911 (E911) emergency service in a data communications network, said method comprising:
- (a) providing an E911-enablement device coupled to a GPS receiver, wherein said E911-enablement device is located in-line between a Voice over Internet Protocol (VoIP) telephone and a network access point, wherein said E911-enablement device;
(i) detects a 911 call;
(ii) intercepts said 911 call packet stream, (iii) receives geographic location information from said GPS receiver, and (iv) inserts said geographic location information into said 911 call packet stream; and
(b) transmitting said 911 call packet stream comprising said geographic location information to a Public Safety Answering Point (PSAP) of said E911 emergency service, thereby permitting said E911 emergency service to identify the geographic location of origination of said 911 call.

Abstract
The present invention provides systems and methods for supporting enhanced 911 (E911) emergency services in data communications networks that includes Voice over Internet Protocol (VoIP) telephones, by facilitating the identification of the geographic location of a VoIP telephone. The invention generally provides GPS-based geographic location information to the E911 emergency services network. In one embodiment, an E911-enablement system including an E911-enablement device coupled to a GPS receiver is provided. The E911-enablement device then inserts geographic location information obtained from the GPS receiver into 911 call packet streams to provide accurate location information to the E911 emergency services network.
