Systems and techniques for routing emergency communications to appropriate public safety answering points (PSAPs) based on location information associated with the communications are provided. Currently, only imprecise location information is available for call routing, and retrieving the imprecise location information requires a slow, expensive query to an automatic location identification (ALI) database. The present disclosure obtains location information that can be used for routing without performing the query to the ALI database, and also incorporates the use of precise location information available from mobile device providers (when available). Similar techniques for routing other types communications to other destination devices based on location information are also disclosed.

Systems and methods for improving routing of communications to emergency services

An emergency gateway can receive carrier location information from a carrier location server for an end-user device that initiated an emergency services call. The emergency gateway can also receive supplemental location information for the end-user device from a supplemental location server and select one of the carrier location information and the supplemental location information. The emergency gateway can generate routing information for the emergency services call based on the selected location information, wherein the routing information identifies a given Public Safety Answering Point (PSAP) for the emergency services call. Further, the emergency gateway can route the emergency services call to the given PSAP based on the routing information.

Supplemental location information for an emergency services call

A data request is generated (e.g., text, email, SMS, multimedia messaging system (MMS), etc.) from a source device. The data request is delivered to a PSAP or other emergency monitoring service location in a useable format. Exemplary useable formats include a canned voice message, delivery to a call center that translates data to voice, text to speech, and text to instant messaging (IM). Additional information and location are staged for use by the PSAP or other monitoring service location.

The format of the Presence Information Data Format-Location Object (PIDF-LO) as defined by the Internet Engineering Task Force (IETF) is extended or modified to accommodate, within the standard PIDF-LO format, an association of geospacial location to XML content on the Internet. A geospacial location is associated with Extensible Markup Language (XML) content on the Internet. The XML content is identified by a universal resource locator (URL), and associated with geospatial location information (either a specific location, zone, or direction). The URL is inserted into a &#x3c;presence . . . &#x3e; section of a Presence Information Data Format-Location Object (PIDF-LO) compliant document as defined by the Internet Engineering Task Force (IETF). In this way, geospacial location information is associated with Internet based XML content using a standard PIDF-LO format.

A gateway can be configured to receive an emergency event message in a predefined format via a network. The emergency event message can characterize a location and a nature of an emergency event. The gateway can also be configured to identify a particular Public Safety Answering Point (PSAP) customer premise equipment (CPE) to service the emergency event. The gateway can further be configured determine a format of messages employable by the particular PSAP. The gateway can still further be configured to provide the particular PSAP CPE with an output message in the format employable by the particular PSAP CPE. The output message can characterize the nature and the location of the emergency event.

Dynamically selecting and facilitating stored caller information to a communications recipient device with a communications event, based on communication recipient credentials (e.g. MDN, etc.), preferences outlined in a subscriber profile associated with a relevant calling device, and other variables, e.g., time of day, etc. A subscriber provisions subscriber preferences and subscriber information associated with users of a subscribing communications device in to a subscriber profile, for use during a communications event. Subscriber preferences place restrictive conditions on stored subscriber information that may be transmitted with a communications event initiated by a corresponding communications device. A content collection node dynamically selects customized caller information via a subscriber information content collection process. Customized caller information is transmitted to appropriate recipient devices with a corresponding communications event. In the event of a 911 communications event, customized caller information may be transmitted to emergency dispatch personnel via the legacy E2 query interface.

Wireless emergency caller profile data delivery over a legacy interface

The risk that an incoming emergency call is a prank call is presented in real-time to the called party, in the form of, e.g., an index of suspicion. An index of suspicion aggregation server quantifies, qualifies, and aggregates risks, suspicions, and/or threats relevant to a call center to formulate a scale of suspicion. Metrics are acquired (e.g., calling device location information, device configuration information, caller information, etc.) relevant to each communications request made to a call center and uses acquired metrics to rate communications requests based on a known scale of suspicion. Once a suspicion rating is determined for a communications request, the communications request is routed to a relevant call-taker terminal, as is the index of suspicion for that incoming call. Real time presentation of the index of suspicion enables call-takers to make better call-handling decisions based on risk analysis and historical call data associated with a given caller.

The format of the Presence Information Data Format-Location Object (PIDF-LO) as defined by the Internet Engineering Task Force (IETF) is extended or modified to accommodate, within the standard PIDF-LO format, an association of geospacial location to virtual content on the Internet. A filename of virtual content is associated with geospatial location information (either a specific location, zone, or direction). The filename is inserted into a &#x3c;presence . . . &#x3e; section of a Presence Information Data Format-Location Object (PIDF-LO) compliant document as defined by the Internet Engineering Task Force (IETF). In this way, geospacial location information is associated with Internet based virtual content using a standard PIDF-LO format.
