Systems and methods for alternative routing of voice over IP originated emergency calls
First Claim
1. A device for routing a 911 call from a caller device, comprising:
- a processor; and
a memory having stored thereon instructions which, when executed by the processor, cause the processor to perform operations comprising;
receiving a caller override signal from the caller device for overriding registered location information associated with an account of the caller, wherein the caller override signal is initiated by the caller device responsive to the caller device;
displaying a geographical address on a display of the caller device, wherein the geographical address indicates the registered location information, providing a notification on the display that the 911 call from the caller device will be routed based on the geographical address, providing a selectable caller override option for overriding the routing of the 911 call based on the geographical address, and receiving a selection of the caller override option; and
in response to the caller override signal;
performing an Internet Protocol (IP) geolocation measurement based on an originating IP address of the 911 call; and
routing the 911 call to a call center based on the results of the IP geolocation measurement, wherein if the IP geolocation measurement returns partial geolocation data, the 911 call is routed to the call center associated with a highest resolution part of the geolocation data.

Abstract
Systems and methods are described for routing Voice over Internet Protocol (VoIP) originated emergency calls. Where registered location information is not available, the present invention can attempt to identify an appropriate emergency call receiving office based on available information regarding the caller'"'"'s physical location. Such information can include the IP address of the caller and, where the VoIP device is a dual mode device, the location of the last cellular base station accessed by the device. Where registered location information does exist, the present invention offers methods for ensuring that the registered location information is not obsolete and in need of updating and, in some cases, providing a manual override of call routing to the caller.

8. A caller device, comprising:
-
a display configured to display a geographical address of the caller device, wherein the geographical address indicates registered location information associated with an account of the caller, and to provide a notification that a 911 call from the caller device will be routed based on the geographical address; and a softkey configured to provide a selectable caller override option for overriding the routing of the 911 call based on the geographical address, wherein upon receipt of selection of the caller override option, the caller device sends a caller override signal to a service provider for overriding the registered location, and in response to the caller override signal, the service provider performs an Internet Protocol (IP) geolocation measurement based on an originating IP address of the 911 call from the caller device and routes the 911 call to a call center, based on the results of the IP geolocation measurement, wherein if the IP geolocation measurement returns partial geolocation data, routing includes routing the 911 call to the call center associated with a highest resolution part of the geolocation data. - View Dependent Claims (9, 10, 11, 12)
