Abstract

An emergency call handling system can provide emergency call routing and processing that compliments or modifies the routing and processing provided by conventional enhanced 911 (E-911) and next generation 911 (NG-911) systems. Both the routing and processing can be based on rule sets detailed in emergency call handling profiles (ECHPs). Any entity (e.g., SIP servers, switches, terminals, etc.) within the system can process and route the emergency call by executing the rule sets within the ECHPs associated with the call. The ECHPs are delivered to the entities within the system by value or by reference. A SIP server, e.g., may execute all or a subset of the rule set, and may communicate with an application server to execute other subsets of the rule set.

Claims20

Dependent claims

A method for processing an emergency service call based on an emergency call handling profile, the method comprising:

(a) determining, by a session initiation protocol (SIP) server, via a location information service (LIS) a location of a device making the call;
(b) communicating, by the SIP server to an emergency call handling profile (ECHP) database, information on the location of the device, the ECHP database selecting an emergency call handling (ECH) profile based on the information, the ECH profile comprising a rule set for handling an emergency service call;
(c) inserting, by the SIP server, a uniform resource locator to the ECH profile, received from the ECHP database, in a header of the SIP request
(d) forwarding, by the SIP server, the SIP request to a second SIP server;
(e) obtaining, by the second SIP server responsive to receiving a SIP request for a call to an emergency service, the ECHP profile from the SIP request;
(f) identifying, by the second SIP server, one or more instructions of the rule set from the ECHP profile;
(g) communicating, by the second SIP server responsive to the one or more instructions, with an application server to execute an instruction of the one or more instructions of the ECH profile;
and
(h) terminating, by the second SIP server responsive to the SIP request, the call with a public safety answering point (PSAP).
