Bi-directional messaging for an emergency services network
View Patent ↗The invention includes a communication network that comprises a conforming emergency system coupled to an emergency services network by a media channel. The emergency services network includes a resource coupled to a plurality of emergency services. When in operation, the conforming emergency system transmits an emergency event message to the resource over the media channel. The emergency event message includes a retrieval key. Responsive to receiving the emergency event message and the retrieval key, the resource initiates an emergency event session corresponding with the retrieval key. During the emergency event session, the resource transmits multiple responses to the conforming emergency system. Also during the emergency event session, the resource receives information corresponding with the retrieval key from at least one of the emergency services, and transmits the multiple responses containing the information.
1. A communication network for providing emergency services, the communication network comprising:
an emergency services network comprising a resource connected to a plurality of emergency services; and
a conforming emergency system (CES) connected to the resource of the emergency services network by a media channel,
wherein the CES is configured to transmit, responsive to an emergency event, an emergency event message to the resource via the media channel, where the emergency event message includes a retrieval key; and
wherein the resource is configured to initiate, responsive to the retrieval key in the emergency event message, an emergency event session corresponding with the retrieval key, and is further configured to transmit multiple responses to the CES during the emergency event session responsive to the emergency event message.
2. The communication network of claim 1 wherein:
the resource is configured to transmit, responsive to receipt of information corresponding with the retrieval key from at least one of the emergency services, the multiple responses containing the information from the at least one emergency service.
3. The communication network of claim 2 wherein:
the resource is configured to transmit individual responses further responsive to receiving information from individual emergency services.
4. The communication network of claim 1 wherein:
the resource is configured to query a first emergency service for first information corresponding with the retrieval key and is configured to transmit a first response containing the first information to the CES responsive to receiving the first information from the first emergency service.
5. The communication network of claim 4 wherein:
the resource is configured to query a second emergency service for second information corresponding with the retrieval key and is configured to transmit a second response containing the second information to the CES responsive to receiving the second information from the second emergency service.
6. The communication network of claim 5 wherein:
the resource is configured to query a third emergency service for third information corresponding with the retrieval key and is configured to transmit a third response containing the third information to the CES responsive to receiving the third information from the third emergency service.
7. The communication network of claim 1 wherein the CES comprises a computer system for a Public Safety Answering Point (PSAP).
8. The communication network of claim 1 wherein the CES comprises a computer system for one of a hospital, a police department, a fire station, a fire alarm company, a security company, an ambulance service, a state 9-1-1 coordinator, the Federal Emergency Management Agency (FEMA), the Department of Homeland Security, the National Geophysical Data Center, or the Center for Disease Control (CDC).
9. The communication network of claim 1 wherein the resource comprises a response gateway.
10. The communication network of claim 1 wherein the emergency service comprises at least one of an ALI database, a Mobile Positioning Center (MPC), a Gateway Mobile Location Center (GMLC), an Emergency Auxiliary Service Provider (EASP), and a Voice over Internet Protocol (VoIP) server.
11. The communication network of claim 1 wherein the retrieval key comprises one of a telephone number, a network address, a Session Initiation Protocol (SIP) address, a trunk ID, a social security number, a street address, an employee ID, an email address, and an incident ID.
12. The communication network of claim 1 wherein information contained in the responses comprises one of streaming video, streaming audio, graphics data, voice, text or binary data, or executable instructions or scripts.
13. The communication network of claim 1 wherein:
the resource is configured to transmit another emergency event message to the CES, where the other emergency event message includes another retrieval key, is configured to initiate another emergency event session corresponding with the other retrieval key, and is configured to transmit multiple responses to the CES during the other emergency event session.
14. A method of operating a communication network for providing emergency services, wherein the communication network includes an emergency services network comprising a resource connected to a plurality of emergency services and a conforming emergency system (CES) connected to the resource of the emergency services network by a media channel, the method comprising the steps of:
transmitting an emergency event message that includes a retrieval key from the CES to the resource via the media channel; and
receiving the emergency event message in the resource, initiating an emergency event session corresponding with the retrieval key, and transmitting multiple responses to the CES via the media channel during the emergency event session responsive to the emergency event message.
15. The method of claim 14 further comprising the steps of:
receiving information corresponding with the retrieval key from at least one of the emergency services, and transmitting the multiple responses containing the information from the at least one emergency service.
16. The method of claim 15 wherein the step of transmitting multiple responses comprises transmitting individual responses further responsive to receiving information from individual emergency services.
17. The method of claim 14 further comprising the steps of:
querying a first emergency service for first information corresponding with the retrieval key, receiving the first information from the first emergency service, and transmitting a first response containing the first information to the CES responsive to receiving the first information from the first emergency service.
18. The method of claim 17 further comprising the steps of:
querying a second emergency service for second information corresponding with the retrieval key, receiving the second information from the second emergency service, and transmitting a second response containing the second information to the CES responsive to receiving the second information from the second emergency service.
19. The method of claim 18 further comprising the steps of:
querying a third emergency service for third information corresponding with the retrieval key, receiving the third information from the second emergency service, and transmitting a third response containing the third information to the CES responsive to receiving the third information from the third emergency service.
20. The method of claim 14 wherein the step of transmitting multiple responses to the CES comprises:
transmitting the multiple responses to the CES in XML messages.
21. The method of claim 14 further comprising the steps of:
transmitting another emergency event message from the resource to the CES, where the other emergency event message includes another retrieval key, initiating another emergency event session corresponding with the other retrieval key, and transmitting multiple responses to the CES during the other emergency event session.
