Internet protocol (IP) emergency connections (ITEC) telephony
First Claim
1. A method for processing an emergency call made from a device connected to a network entity on a private network, said private network including one or more network entities, said method comprising the steps of:
- a) assigning a source group index (SGI) to each network entity port;
b) identifying emergency calls;
c) determining an origination port for each identified port emergency call;
d) identifying a public safety answering point (PSAP) jurisdiction corresponding to the SGI assigned to each determined origination port; and
e) connecting each identified emergency call with a corresponding identified PSAP.

Abstract
An IP Telephony Emergency Connections (ITEC) system and method that determines the precise origin of an emergency call and routes the call to the proper Public Service Answering Point (PSAP). A source-based routing mechanism is provided in an IP telephony type network, such as a VoIP or IP over LAN/ATM. Emergency calls are routed to the correct PSAP jurisdiction. Each server/switch may include the mechanism such that the IP Telephony network can identify an E911 connection and egress to a public network at a point closest to the emergency call point of origin. Whenever an emergency number call is made, the call'"'"'s origin is determined during call setup establishment. Every port or end user jack in the network is assigned a Source Group Index (SGI), which is a number or index representing each PSAP jurisdiction in the network. All ports/jacks within the same PSAP jurisdiction are assigned the same SGI. Users may be in different areas of multiple PSAP jurisdictions.

11. A network including an apparatus for processing emergency calls made from connected devices, said network comprising:
-
a plurality of network entities communicating with each other;
a plurality of devices connected to said network entities, at least one network entity having two or more connected said devices;
a network area router (NAR) in at least one network entity; and
an emergency connection identifier (ECI) module in at least one network entity with one or more ports, said ECI module in communication with said NAR, said ECI module identifying emergency calls made from devices connected to said one or more ports and forwarding identified emergency calls to said NAR, said NAR identifying a public safety access point (PSAP) corresponding to a point of origin of each identified emergency call and forwarding said each identified emergency call to said PSAP. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
