EMERGENCY SERVICES CALL DELIVERY FROM A LEGACY COMMUNICATIONS DEVICE TO A VOIP PSAP
First Claim
1. An application server for use by an emergency services network comprising:
- a logic control configured to determine routing instructions responsive to routing instructions requests from said emergency services network and also configured to determine whether said routing instructions request includes a location object and an identification of a requesting communications device;
a database configured to return a destination identification responsive to a query comprising said location object from said logic control; and
a data communications module configured to query a remote database responsive to a query comprising said identification of said requesting communications device and configured to forward a destination identification to said logic control responsive to receipt of said destination identification from said remote database.

Abstract
An Emergency Services Application Server (ES-AS) that obtains routing instructions for both VoIP-originated and non-VoIP-originated calls to emergency services numbers (e.g., 9-1-1). If the emergency request is a VoIP-originated call and includes a location object, the ES-AS queries its database using the location object to obtain routing information. If a location object is not provided, the ES-AS queries a location information server to obtain a location object. The ES-AS then uses the location object to query its database. If the call is originated by legacy user equipment, the ES-AS accesses a legacy automatic location information system to obtain location information and the associated PSAP. The ES-AS then queries its database with the returned information to refine routing information needed to route the call to the identified PSAP. The ES-AS includes a web services interface that allows a PSAP or authorized agency to change routing instructions dynamically, which overrides any static data in the ES-AS'"'"'s routing database.

16. A method for use in an emergency services network for routing an emergency services call to a public safety answering point (PSAP), said emergency services call comprising an identification of a calling communications device, said method comprising:
-
determining whether a location object is included with said emergency services call includes a location object; querying a remote database with said identification of said calling communications device to obtain a location object if said location object is not present in said emergency services call; obtaining an identification of a PSAP (PSAP ID) responsive to said location object; and routing said emergency services call responsive to said PSAP ID. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A method for use in an emergency services network for routing an emergency services call to a public safety answering point (PSAP), said emergency services call comprising an identification of a calling communications device, said method comprising:
-
registering a PSAP ID responsive to a request from a PSAP; determining whether a location object is included with said emergency services call includes a location object; querying a remote database with said identification of said calling communications device to obtain a location object if said location object is not present in said emergency services call; obtaining an identification of a PSAP (PSAP ID) responsive to said location object; determining whether said PSAP ID is registered; and routing said emergency services call responsive to said PSAP ID responsive to a determination that said PSAP ID is registered. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33)
