Methods and apparatus for contingency communications
View Patent ↗Methods and systems for contingency communication are disclosed. In one embodiment, a method for providing emergency services may be performed by a base station operating in a communication system. In an embodiment, the method for providing emergency services includes transmitting a beacon signal to indicate an emergency status to enable portable devices to operate in a stress mode. A distress signal may be transmitted by a mobile device in response to the beacon signal to the base station, wherein the distress signal carries information at least comprising user identity associated with the mobile device, geolocation of the mobile device, or biometrics of a user of the mobile device.
1. A method for providing communication by a base station in a network comprising base stations and portable devices, the method comprising:
transmitting a beacon signal indicating an emergency status to a portable device, the beacon signal usable by the portable device to determine whether to enter a stress mode;
receiving an acknowledgement signal from the portable device in response to the beacon signal; and
deriving, from the received acknowledgement signal, information associated with the portable device or a user of the portable device.
2. The method of claim 1 , further comprising transmitting an instruction to activate a monitoring device on the portable device.
3. The method of claim 1 , wherein the beacon signal is generated to facilitate in-building penetration of the transmitted beacon signal.
4. The method of claim 3 , wherein the beacon signal is a spread-spectrum signal with high spreading gain or coding gain.
5. The method of claim 1 , wherein the acknowledgement signal carries information selected from a group comprising: identity of the portable device, position of the portable device, and biometrics of the user of the portable device.
6. The method of claim 1 , further comprising transmitting a scheduling signal containing information indicating instructions for transmitting the acknowledgement signal.
7. The method of claim 1 , further comprising accessing a database or a list of subscribers of a cellular network covering a geographical area near or overlapping with a geographical area covered by the base station.
8. The method of claim 1 , further comprising accessing a database or a list of subscribers of a cellular network covering a geographical area near or overlapping with a geographical area covered by the base station.
9. A base station in a communication network comprising base stations and portable devices, the base station configured to:
transmit a beacon signal indicating an emergency status to enable portable devices to determine whether to enter a stress mode;
receive an acknowledgement signal from a portable device in response to the beacon signal; and
derive, from the received acknowledgement signal, information associated with the portable device or a user of the portable device.
10. The base station of claim 9 , further configured to transmit a scheduling signal containing information indicating instructions for transmitting the acknowledgement signal.
11. The base station of claim 9 , further configured to access a database or a list of subscribers of a cellular network covering a geographical area near or overlapping with a geographical area covered by the base station.
12. The base station of claim 9 , wherein the base station is a mobile communication device configured to be mounted on a vehicle or a portable communication device configured to be carried by an emergency responder.
13. The base station of claim 9 , further configured to transmit an instruction to activate a monitoring device on the portable device.
14. The base station of claim 9 , wherein the beacon signal is generated to facilitate in-building penetration of the transmitted beacon signal.
15. The base station of claim 14 , wherein the beacon signal is a spread-spectrum signal with high spreading gain or coding gain.
16. The base station of claim 9 , wherein the acknowledgement signal carries information selected from a group comprising: identity of the portable device, position of the portable device, and biometrics of the user of the portable device.
17. A non-transitory computer readable storage medium storing thereon computer executable instructions for communicating by a base station in a network comprising base stations and portable devices, the computer readable storage medium comprising:
instructions for transmitting a beacon signal indicating an emergency status to a portable device, the beacon signal usable by the portable device to determine whether to enter a stress mode;
instructions for receiving an acknowledgement signal from the portable device in response to the beacon signal; and
instructions for deriving, from the received acknowledgement signal, information associated with the portable device or a user of the portable device.
18. The computer readable storage medium of claim 17 , further comprising instructions for transmitting an instruction to activate a monitoring device on the portable device.
19. The computer readable storage medium of claim 17 , wherein the acknowledgement signal carries information selected from a group comprising: identity of the portable device, position of the portable device, and biometrics of the user of the portable device.
20. The computer readable storage medium of claim 17 , further comprising instructions for transmitting a scheduling signal containing information indicating instructions for transmitting the acknowledgement signal.
