Advanced port-based E911 strategy for IP telephony
First Claim
1. A method for providing emergency location information to an emergency service provider, comprising:
- providing an enterprise network comprising;
a wireless access point;
a wireless communication device in communication with the wireless access point;
an Open Systems Interconnect (OSI) switch in communication with the wireless access point;
an enterprise switch;
wherein the enterprise network corresponds to a plurality of Emergency Location Information Numbers (ELINs) associated with differing segments of the enterprise network, and wherein the OSI switch serves at least one of the differing segments;
when a predetermined first event occurs, the wireless access point obtaining a wireless access point identifier and an electronic address of the wireless communication device serviced by the wireless access point; and
when at least one of the predetermined first event and a predetermined second event occurs, the enterprise switch obtaining at least one of the wireless access point identifier and a wireless communication device unique identifier, wherein the first and second events are unrelated to the initiation of a contact to a universal emergency number.

Abstract
An enterprise network includes at least one communication device 208-1, an Open Systems Interconnect (OSI) Layer 2 switch 206, and a corresponding enterprise switch 208. The communication device 208-1 is connected to at least one of an access point 904-1 and a respective port 207-1 of the Layer 2 switch 206. The enterprise network includes a plurality of Emergency Location Information Numbers (ELINs) corresponding to differing segments of the enterprise network. The Layer 2 switch 206 serves at least one of the differing segments. The communication device 208-1 includes a discovery agent 252 operable, when a predetermined first event occurs, to obtain from the Layer 2 switch 206 at least one of an access point identifier, a switch identifier from the Layer 2 switch 206, and a port identifier identifying the respective port 207-1.

14. An enterprise network comprising:
-
an Open Systems Interconnect (OSI) switch, where the enterprise network comprises a plurality of Emergency Location Information Numbers ELINs corresponding to differing segments of the enterprise network, and wherein the OSI switch serves at least one of the differing segments; a wireless access point in communication with the OSI switch and an enterprise switch; a wireless communication device in communication with the wireless access point, the wireless communication device comprising; a discovery agent operable, when a predetermined first event occurs, to obtain from the wireless access point a wireless access point identifier; and the enterprise switch, when at least one of the predetermined first event and a predetermined second event occurs, operable to obtain the wireless access point identifier and maintain a set of data structures mapping the wireless access point identifier to an ELIN corresponding to a network segment comprising the wireless communication device. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. In an enterprise network comprising at least one wireless communication device, an Open Systems Interconnect (OSI) switch and a corresponding enterprise switch, wherein the at least one wireless communication device is wirelessly connected to a wireless access point, the wireless access point being connected to the OSI switch, the enterprise network comprising a plurality of Emergency Location Information Numbers (ELINs) corresponding to differing segments of the enterprise network, and wherein the OSI switch serves at least one of the differing segments, a system comprising:
-
when a predetermined first event occurs, means for obtaining a wireless access point identifier and an electronic address of the at least one wireless communication device serviced by the wireless access point; and when at least one of the predetermined first event and a predetermined second event occurs, means for obtaining at least one of the wireless access point identifier and a wireless communication device unique identifier, wherein the first and second events are unrelated to the initiation of a contact to a universal emergency number. - View Dependent Claims (23, 24, 25, 26)
