System, method and apparatus for supporting E911 emergency services in a data communications network
First Claim
1. A method of supporting enhanced 911 (E911) emergency services in a network access device, comprising:
- (a) assigning a physical location identifier to an input port of the network access device;
(b) transmitting an automatic report to an E911 database management system (DBMS) when a user device is coupled to said input port;
(c) transmitting a unique device identifier of said user device to said E911 DBMS in response to a first query from said E911 DBMS; and
(d) if said user device is a VoIP telephone, then transmitting said physical location identifier to said E911 DBMS in response to a second query from said E911 DBMS;
whereby said E911 DBMS updates an automatic location identification database with said physical location identifier of said VoIP telephone.

Abstract
A system, method and apparatus for supporting enhanced 911 (E911) emergency services, in a data communications network that includes Voice over Internet Protocol (VoIP) telephones. A network system includes a host network communicatively coupled to an E911 database management system, a network access device, and a VoIP telephone communicatively coupled to an input port of the network access device. The network access device is adapted to assign a physical location identifier to an input port, to authenticate the VoIP telephone, wherein the authentication includes receiving a unique device identifier from the VoIP telephone, and to transmit the location identifier and the unique device identifier to the E911 database management system. The E911 database management system is permitted to store the physical location identifier in association with the unique device identifier.

7. A network access device that supports enhanced 911 (E911) emergency services, comprising:
-
an input port; a switching fabric for routing data received via said input port to at least one output port; and control logic adapted to assign a physical location identifier to said input port, transmit an automatic report to an E911 database management system (DBMS) when a user device is coupled to said input port, transmit a unique device identifier to said E911 DBMS in response to a first query from said E911 DBMS, whereby said E911 DBMS determines whether said user device is a VoIP telephone, and if said user device is a VoIP telephone, transmit said physical location identifier to said E911 DBMS in response to a second query from said E911 DBMS, thereby permitting said E911 database management system to store said physical location identifier in association with said unique device identifier. - View Dependent Claims (8, 9, 10, 11, 12)

13. A network system for supporting enhanced 911 (E911) emergency services, comprising:
-
a host network communicatively coupled to an E911 database management system (DBMS); a network access device communicatively coupled to said host network; and a user device communicatively coupled to an input port of said network access device; wherein said network access device is adapted to assign a physical location identifier to said input port, to automatically transmit a report to said E911 DBMS when said user device is coupled to said input port, to transmit a unique device identifier to said E911 DBMS in response to a first query from said E911 DBMS, and, if said user device is a VoIP telephone, to transmit said physical location identifier to said E911 DBMS in response to a second query from said E911 DBMS; thereby permitting said E911 database management system to store said physical location identifier in association with said unique device identifier. - View Dependent Claims (14, 15, 16, 17, 18)
