Advanced port-based E911 strategy for IP telephony
First Claim
1. A method for providing emergency location information to an emergency service provider, comprising:
- (a) providing an enterprise network comprising at least one communication device, an Open Systems Interconnect (OSI) switch and a corresponding enterprise switch, wherein the communication device is wirelessly connected to an access point and the access point is connected to the OSI switch, the enterprise network corresponding 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;
(b) when a predetermined first event occurs, the access point obtaining a unique access point identifier and an electronic address of the communication device serviced by the access point; and
(c) when at least one of the predetermined first event and a predetermined second event occurs, the enterprise switch obtaining at least one of the access point identifier and a 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. In an enterprise network comprising at least one communication device, an Open Systems Interconnect (OSI) switch and a corresponding enterprise switch, wherein the communication device is wirelessly connected to an access point, the 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, the at least one communication device comprising:
a discovery agent operable, when a predetermined first event occurs, to obtain from the access point an access point identifier and when at least one of the predetermined first event and a predetermined second event occurs, the enterprise switch is operable to obtain the access point identifier and maintain a set of data structures mapping the access point identifier to an ELIN corresponding to a network segment comprising the communication device. - View Dependent Claims (16, 17, 20, 21, 22, 23, 24)
