Text message generation for emergency services as a backup to voice communications
View Patent ↗A mobile device may detect when a calling party dials an emergency service to request emergency assistance. Following input of the dialed digits, the device may automatically generate a text message in addition to initiating a voice call, both of which may be transmitted over a wireless data network. The wireless network may correlate the two calls as originating from the same emergency situation and may attempt to deliver the two calls to a Public Services Answering Position (PSAP) at an appropriate emergency center. If the PSAP does not receive a voice call, the PSAP may communicate with the device via test messaging.
1. A method comprising:
receiving an indication of an emergency voice call;
receiving an indication of an emergency text message;
generating an identifier indicating that the emergency voice call and the emergency text message are correlated based on the emergency voice call and the emergency text message being generated by a common source, the identifier comprising:
an indication of the common source; and
a correlation number;
generating first signaling comprising the indication of the emergency voice call and the identifier;
generating second signaling comprising the indication of the emergency text message and the identifier;
providing the first signaling via a first communication network; and
providing the second signaling via a second communication network.
2. The method of claim 1 , wherein:
the first network differs from the second network.
3. The method of claim 1 , wherein:
the first network comprises circuitry for communicating a voice call; and
the second network comprises circuitry for communicating data.
4. The method of claim 1 , wherein:
the indication of the emergency text message is indicative of being automatically generated upon dialing a number for the emergency voice call.
5. The method of claim 1 , wherein:
the second signaling comprises a data packet comprising the identifier.
6. The method of claim 1 , wherein:
the second signaling comprises a IP data packet comprising the identifier in a header of the IP data packet.
7. The method of claim 1 , wherein:
an intended recipient of the emergency voice call is a public services answering position.
8. The method of claim 1 , wherein:
the emergency text message comprises a an indication of sender of the emergency text message.
9. The method of claim 1 , wherein:
the emergency text message comprises a an indication of a location of a device from which the emergency text message was sent.
10. The method of claim 1 , wherein:
the emergency text message comprises a text message resulting from a voice to text conversion.
11. A method comprising:
receiving an indication of a voice call;
determining that the voice call is an emergency voice call;
upon determining that the voice call is an emergency voice call, automatically generating an emergency text message;
generating an identifier indicating that the emergency voice call and the emergency text message are correlated based on the emergency voice call and the emergency text message being generated by a common source, the identifier comprising:
an indication of the common source; and
a correlation number;
generating first signaling comprising the indication of the emergency voice call and the identifier;
generating second signaling comprising the indication of the emergency text message and the identifier;
providing the first signaling via a first communication network; and
providing the second signaling via a second communication network.
12. The method of claim 11 , wherein:
the indication of the initiation of the emergency voice call comprised dialed digits.
13. The method of claim 11 , wherein:
the indication of the initiation of the emergency voice call comprised dialed digits comprising numbers 9, 1, and 1.
14. The method of claim 11 , wherein:
an intended recipient of the emergency voice call is a public services answering position.
15. The method of claim 11 , wherein:
the voice call is determined to be an emergency voice call based on a number dialed being a number of a predetermined list of numbers.
16. The method of claim 11 , wherein:
the emergency text message comprises a predetermined text message.
17. The method of claim 11 , wherein:
the emergency text message comprises a an indication of sender of the emergency text message.
18. The method of claim 11 , wherein:
the emergency text message comprises a an indication of a location of the device.
19. The method of claim 11 , wherein:
the emergency text message comprises a text message resulting from a voice to text conversion.
20. A computer-readable storage medium comprising executable instruction that when executed by a processor cause the processor to effectuating operations comprising:
receiving an indication of an emergency voice call;
receiving an indication of an emergency text message;
generating an identifier indicating that the emergency voice call and the emergency text message are correlated based on the emergency voice call and the emergency text message being generated by a common source, the identifier comprising:
an indication of the common source; and
a correlation number;
generating first signaling comprising the indication of the emergency voice call and the identifier;
generating second signaling comprising the indication of the emergency text message and the identifier;
providing the first signaling via a first communication network; and
providing the second signaling via a second communication network.
