ABSTRACT OF THE DISCLOSURE
1.0 BACKGROUND OF THE INVENTION
1.1 Field of the Invention
This invention relates to telecommunication networks and more particularly, to a method of third-party notification which responds whenever a call to an emergency service has occurred by placing real-time incident and response information content into an outbound notification call to a list of predetermined telephone numbers.
1.2 Description of the Prior Art
Nationwide, a non-toll telephone number 9-1-1 has been designated for calls relating to emergencies that threaten human life or property. Similar telephone numbers have been designated in many foreign countries. The calls are directed by the telephone company's End Office/Central Office (CO) and 9-1-1 Tandem to a Public Safety Answering Point (PSAP) where the calling number Automatic Number Identification (ANI) is displayed on a viewing screen. Most areas now have “Enhanced 9-1-1” which allows selective routing and through which both the calling number and address of the caller are displayed on a viewing screen at the PSAP, thus enabling the emergency agency to locate the caller if the call is interrupted. The address of the caller is obtained from the telephone company's customer records Automatic Location Identification (ALI) database system. Currently mobile communications systems, such as cell phones, low earth orbit (LEO) satellite phones, wireless IP devices, etc. do not provide a way for a Public Safety Answering Point (PSAP) to determine the actual physical location or address (the street address or coordinates) where the device is located. This has been identified as a major obstacle in providing the enhanced 9-1-1 features for wireless cell phones, one of the key elements of which is locating the caller.
Personnel at the PSAP talk to the caller and route the call to the appropriate agency equipped to handle the emergency, such as ambulance; fire and rescue; police, sheriff and highway patrol; or Coast Guard, Search and Rescue. Third parties, other than the agency responding to the emergency, may also be notified that a 9-1-1 call has been placed. Prior approaches to call notification and/or routing are represented by the following prior art patents:
Carrier, et. al., U.S. Pat. No. 5,195,126, granted Mar. 16, 1993, for “Emergency Alert and Security Apparatus and Method” discloses a wireline telecommunications system which includes a 9-1-1 and voice message service platform for providing such services as telephone answering, voice mail and call completion. An emergency/safety notification system includes a monitor/router device passively connected to the 9-1-1 Tandem to detect number identification signals. In the event of a 9-1-1 telephone call, the service initiates a voice mail call, which plays a custom message from the calling party to designated third parties. The Carrier patent does not provide for the automatic insertion of the calling party's ANI, the date or the time of the 9-1-1 call, or the name or location or address of the telephone customer. The service is driven from a passive monitor/router at every 9-1-1 Tandem or End/Central Office. The service provides only voice mail in the event of a 9-1-1 call. If no voice mail message is provided by the subscriber, no message is played in the event of a 9-1-1 call.
Pons, et. al., U.S. Pat. No. 5,805,670, granted Sep. 8, 1998, for “Private Notification System for Communicating 9-1-1 Information” discloses an advanced personal safety service that is connected directly to 9-1-1 call centers. To activate the service, subscribers complete a questionnaire providing personal information about their location and household and pay a monthly fee. When a subscriber dials 9-1-1 for help and the call is answered at the PSAP, Automatic Number Identification/Automatic Location Identification (ANI/ALI) data is sent from the E-9-1-1 Controller to a Command Control Center. If the Command Control Center determines the ANI is one of a subscriber, it sends personal information to the PSAP CAD, and the CAD may send information about the incident to the Command Control Center. Police, fire and emergency medical services are provided with personal information about subscribers, such as medical history and preexisting conditions, as well as the location of children, elderly or infirm persons within a dwelling. The Command Control Center personnel may place calls to a preselected list of telephone numbers. The information given to the pre-selected recipients may include response or destination information from the CAD. Thus, the service provides emergency services with personal information about subscribers and alerts pre-selected contacts about the incident.
Reich, et al., U.S. Pat. No. 6,151,385 assigned to the assignee of the present invention describes a computer driven telecommunication system that automatically reacts to all emergency 9-1-1 calls that result in a query to the local telephone company's Automatic Location Identification (ALI) database system. This query may come from a tandem selective router, a 9-1-1 controller, a service control point, or other source of an Automatic Number Identification (ANT). Reaction is based on the Automatic Number Identification (ANI) as provided to the system by the local telephone company through a connection from the ALI database system. Reaction to the input includes evaluation of all ANIs to determine if the ANT is for a customer that has subscribed to the system and, pending positive evaluation, reacting through existing telephone networks by notifying addressable communication devices that a 9-1-1 call has been placed from the subscriber's telephone.
Orwick, et al. U.S. Pat. No. 6,201,856, granted Mar. 13, 2001, for “Emergency telephone call notification service system and method” describes a method for emergency telephone call notification for use in a wireline network. The system includes an advanced intelligent network (AIN) capable switch, a service control point (SCP) having a database of designated contact numbers associated with a service subscriber telephone number, and an intelligent peripheral in communication with the SCP for contacting the designated contact numbers. The method recognizes an N11 trigger at the switch in communication with the subscriber telephone (e.g. a dialed 911 call) in response to which the SCP initiates telephone calls, via the intelligent peripheral, to each of the contact numbers corresponding to the telephone number of the subscriber making the emergency telephone call.
The intelligent peripheral supplies a caller ID message to the designated telephone number and plays a prerecorded message if a person answers the emergency call notification call. The system employs a caller ID generator comprising a pre-designated message stored in memory. The intelligent peripheral further comprises a plurality of prerecorded message templates, for example, a prerecorded message for transmission to an answering machine. Each
