Abstract

An emergency call system having an emergency call sensing apparatus for transmitting an emergency radio signal upon sensing an emergency event, and at least one mobile unit, which can be located near the emergency call sensing apparatus to receive the emergency radio signal and to establish subsequently an emergency call to a predefined destination. The respective radio interface units of the emergency call sensing apparatus and the mobile unit handling emergency radio signal communications implement NFC technology, so that the emergency call sensing apparatus is able to freely access the mobile unit without using any access control command data generated by the mobile unit.

Claims

1. An emergency call system comprising:

an emergency call sensing apparatus including;

an emergency event sensor adapted to sense an emergency event and to provide a command to send an emergency radio signal;

a first wireless communication device adapted to communicate with a mobile unit to send an emergency radio signal upon receipt of the command sent by the emergency event sensor; and

an emergency control unit to coordinate tasks, to handle a communication with the mobile unit through the first wireless communication device and to provide emergency call data in case of an emergency event sensed by the emergency event sensor; and

at least one mobile unit that can be located near the emergency call sensing apparatus, said at least one mobile unit including;

a second wireless communication device operative to communicate with the first wireless communication device to receive the emergency radio signal;

a third wireless communication device operative to establish an emergency call through a wireless public communication network to a predefined destination upon receipt of the emergency radio signal; and

a mobile control unit to coordinate tasks between the second wireless communication device and the third wireless communication device.

2. The emergency call system of claim 1, wherein

the first wireless communication device implements Near Field Communication (“

NFC”

) technology to transmit the emergency radio signal,

the second wireless communication device implements NFC technology to receive the emergency radio signal from the emergency call sensing apparatus, and

the emergency call sensing apparatus is able to access the at least one mobile unit without using any access control command data generated by the at least one mobile unit.

3. The emergency call system of claim 1, wherein the emergency call sensing apparatus further comprises an emergency call storage unit containing the emergency call data related to the emergency radio signal as prerecorded voice codec data and/or emergency call sensing apparatus positioning data.

4. The emergency call system of claim 1, wherein the emergency call sensing apparatus further comprises a positioning signal receiver unit operative to provide positioning data to be incorporated into the emergency radio signal as emergency data.

5. The emergency call system of claim 1, wherein the emergency call sensing apparatus further comprises a voice codec unit operable to convert an analog voice message into a prerecorded voice data message to be incorporated into the emergency radio signal.

6. The emergency call system of claim 1, wherein the at least one mobile unit further comprises a mobile storage data base to store the totality of the emergency data sent by the emergency call sensing apparatus.

7. The emergency call system of claim 1, wherein the mobile unit further comprises a positioning receiver unit operative to receive mobile positioning data, and means for encapsulating the mobile positioning data in the emergency call data to provide complete emergency call data to be sent to the predetermined destination through the third wireless communication device.

8. The emergency call system of claim 1, wherein the mobile unit further comprises an emergency call disabling device operative to deactivate the second wireless communication device in response to a user command.

9. The emergency call system of claim 1, further comprising

a plurality of mobile units operative to be located near the emergency call sensing apparatus wherein each mobile unit including a second wireless communication device implements NFC technology, and

the emergency call sensing apparatus is operative to freely access each mobile unit of the plurality of mobile units without using any access control command generated by each unit of the plurality of mobile units.

10. The emergency call system of claim 9, wherein each the mobile unit includes the means for establishing an emergency call to a same predefined destination when the mobile unit receives an emergency signal from the emergency call sensing apparatus.

11. The emergency call system of claim 1, wherein the emergency call sensing apparatus segments the emergency radio signal into a number of data blocks or transmission bursts using an Automatic Request protocol (“

ARQ”

) to transmit all the data of the emergency radio signal.

12. A method for gaining emergency assistance in an emergency, the method comprising the steps of

determining the occurrence of an emergency event;

transmitting an emergency radio signal through a wireless communication using Near Field Communication (“

NFC”

) technology when the emergency event has been sensed;

receiving the emergency signal transmitted through the wireless communication using NFC technology; and

processing the emergency signal independent of control command data generated by the source of the emergency signal using NFC technology.

13. The method of claim 12 wherein the emergency radio signal includes emergency call data.

14. The method of claim 13 further comprising storing the emergency call data

15. The method of claim 13 wherein emergency call data includes positioning data.

16. The method of claim 13 further comprising receiving at a positioning receiver mobile positioning data.

17. The method of claim 16 further comprising encapsulating the mobile positioning data in the emergency call data and sending the emergency call data to a predetermined destination.

18. The method of claim 12 further comprising segmenting the emergency radio signal into a number of data blocks or transmission bursts using an Automatic Request (“

ARQ”

) protocol to transmit all data of the emergency radio signal.
