Abstract

In response to the triggering of a user'"'"'s mobile terminal, such as through pushing a dedicated button, by inputting a predetermined sequence of digits, through a menu selection, or automatically in response to an external input, a digital record containing user-specific information that is stored in the mobile terminal is packetized and transmitted over a signaling channel through the public wireless network, where the one or more packets are marked as being emergency 911 (E911) packets. From the header information in these packets, a Mobile Switching Center (MSC) in the wireless network, recognizes these E911 packets as being destined to that MSC'"'"'s nearest Public Safety Answering Point (PSAP), and transmits the information contained in those packets to that PSAP.

Claims

1. A method in a public wireless communications system comprising:

at a mobile terminal;

in response to a triggering event initiated by an occurrence of a certain type of situation, transmitting a message on a signaling channel that comprises previously stored user-specific information that is associated with the type of situation that has occurred, information that identifies the mobile terminal, and information that identifies a type of destination to which the message is directed and which is also associated with the type of situation that has occurred, wherein when a mobile switching center in the public wireless communications system receives the message, it determines an actual destination endpoint to which the message should be routed from the type of destination information in the message and routes the message to the actual destination endpoint, the message being routed to the actual destination endpoint without establishing an end-to-end connection between the mobile terminal and the actual destination endpoint.

2. The method of claim 1 wherein the message further comprises a geo-location of the mobile terminal.

3. The method of claim 1 wherein the message further comprises a time and date associated with the triggering event.

4. The method of claim 1 wherein the message further comprises a digitized voice snippet of a user.

5. The method of claim 1 wherein the triggering event is an input entered by a user at the mobile terminal.

6. The method of claim 1 wherein the triggering event is detecting an occurrence of a predetermined event external to the mobile terminal.

7. The method of claim 1 wherein the type of destination is a Public Safety Answering Point (PSAP) and the stored user specific information comprises user medical information.

8. The method of claim 1 wherein the message further comprises a priority, the information being transmitted on the wireless communications system in accordance with the priority.

9. The method of claim 1 wherein the message is transmitted within at least one packet, the at least one packet having a header that indicates the type of destination for the information.

10. The method of claim 1 wherein the signaling channel is an SMS signaling channel.

11. A method in a public wireless communications system comprising:

at a mobile switching center;

receiving on a signaling channel a message that was sent by a mobile terminal in response a triggering event that was initiated in response to an occurrence of a certain type of situation, the message comprising user-specific information that was previously stored at the mobile terminal and is associated with the type of situation that has occurred, information that identifies the mobile terminal, and information that identifies a type of destination to which the message is directed and which is also associated with the type of situation that has occurred,

determining an actual destination endpoint from the type of destination information in the message; and

routing the message to the actual destination endpoint, the message being routed to the actual destination endpoint without establishing an end-to-end connection between the mobile terminal and the actual destination endpoint.

12. The method of claim 11 wherein the actual destination endpoint is a mobile terminal and the received message is forwarded to the mobile terminal at the actual destination endpoint on a signaling channel.

13. The method of claim 11 wherein the actual destination endpoint has an associated email address and the received message is forwarded in an email message sent to the email address.

14. The method of claim 11 wherein the actual destination endpoint is a voice terminal and the user-specific information in the received message is converted to a voice signal and is forwarded to the voice terminal.

15. The method of claim 11 wherein the actual destination endpoint is a data terminal and the received message is forwarded on a data network to the data terminal.

16. The method of claim 11 wherein the received message further comprises a geo-location of the mobile terminal.

17. The method of claim 11 wherein the received message further comprises a time and date associated with the triggering event.

18. The method of claim 11 wherein the received message further comprises a digitized voice snippet of a user.

19. The method of claim 11 wherein the user specific information in the received message comprises user medical information, the actual destination endpoint is a Public Safety Answering Point (PSAP), and the received message is forwarded to the PSAP that is nearest to the mobile switching center.

20. The method of claim 11 wherein the received message is within at least one packet, the packet having a header that indicates a the type of destination for the message.

21. The method of claim 11 wherein the signaling channel is an SMS signaling channel.

22. The method of claim 11 wherein the received message further comprises a priority and the message is routed to the actual destination endpoint in accordance with the priority.

23. A computer readable media tangibly embodying a program of instructions executable by a computer to perform a method at a mobile terminal operating on a public wireless communications system, the method comprising:

in response to a triggering event initiated by an occurrence of a certain type of situation, transmitting a message on a signaling channel that comprises previously stored user-specific information that is associated with the type of situation that has occurred, information that identifies the mobile terminal, and information that identifies a type of destination to which the message is directed and which is also associated with the type of situation that has occurred, wherein when a mobile switching center in the public wireless communications system receives the message, it determines an actual destination endpoint to which the message should be routed from the type of destination information in the message and routes the message to the actual destination endpoint, the message being routed to the actual destination endpoint without establishing an end-to-end connection between the mobile terminal and the actual destination endpoint.

24. A computer readable media tangibly embodying a program of instructions executable by a computer to perform a method at a mobile switching center in a public wireless communications system, the method comprising:

receiving on a signaling channel a message that was sent by a mobile terminal in response to a triggering event that was initiated in response to an occurrence of a certain type of situation, the message comprising user-specific information that was previously stored at the mobile terminal and is associated with the type of situation that has occurred, information that identifies the mobile terminal, and information that identifies a type of destination to which the message is directed and which is also associated with the type of situation that has occurred,

determining an actual destination endpoint from the type of destination information in the message; and

routing the message to the actual destination endpoint, the message being routed to the actual destination endpoint without establishing an end-to-end connection between the mobile terminal and the destination endpoint.
