Abstract

A cordless security system that communicates through a wireless telephone network. A wireless node, having a wireless transceiver adapted to communicate wireless signals with the wireless telephone network, and a cordless transceiver adapted to communicate cordless signals with plural cordless terminal devices enables a cordless local area network. The wireless node also includes a controller that operates to couple telephone calls between the wireless transceiver and the cordless transceiver. The controller routes cordless data packets in the cordless signals through the cordless transceiver and amongst the plural cordless terminal devices. The cordless security system includes plural cordless security sensor terminal devices that communicate cordless sensor signal encoded within a cordless data packet into the cordless local area network. A cordless security control panel terminal device communicates cordless alarm signals encoded within a cordless data packet into the cordless local area network. The control panel also transmits a cordless outgoing audio message within the cordless local area network. A cordless security alarm terminal device, such as a siren produces an audible output.

Claims

1. A cordless security system operable to communicate with a wireless telephone network, comprising:

a wireless node, having;

a wireless transceiver adapted to communicate wireless signals with the wireless telephone network;

a cordless transceiver adapted to communicate cordless signals with plural cordless terminal devices, thereby enabling a cordless local area network;

a cordless security sensor terminal device operable to communicate a cordless sensor signal encoded within a cordless data packet into said cordless local area network upon receipt of an external stimulus;

a cordless security control panel terminal device operable to communicate a cordless alarm signal encoded within a cordless data packet into said cordless local area network upon receipt of said cordless sensor signal, and operable to transmit a cordless outgoing audio message within said cordless local area network, and wherein

said wireless node is operable to receive and route said cordless outgoing audio message through the wireless telephone network to a predetermined telephone number.

2. The system of claim 1, further comprising:

a cordless telephone terminal device operable to communicate cordless signals, including cordless audio signals, within said cordless local area network, thereby enabling telephone communications through said wireless node and into the wireless telephone network.

3. The system of claim 2 wherein said wireless node is operable to route said cordless outgoing message to said cordless telephone terminal device.

4. The system of claim 1, further comprising:

a cordless security alarm terminal device having an alarm output, and operable to activate said alarm output upon receipt of said cordless alarm signal.

5. The system of claim 4, wherein said cordless security alarm terminal device is a cordless siren or a cordless alarm output receiver.

6. The system of claim 1 wherein said cordless data packet portions are uniquely addressed.

7. The system of claim 1 wherein said cordless data packet portions are uniquely addressed with a source and destination cordless terminal device identifier.

8. The system of claim 1, wherein said cordless security control panel further comprises:

a microphone;

a loudspeaker, and

an audio recording means coupled to said microphone and said loudspeaker, and operable to store outgoing message audio signals input to said microphone, and to output said outgoing message audio signals to said loudspeaker.

9. The system of claim 8, wherein said cordless security control panel further comprises:

an alphanumeric display;

a keypad, and

a processor coupled to said alphanumeric display and said keypad, and operable to process security system commands entered via said keypad, and to output security system information to said alphanumeric display.

10. The system of claim 1, wherein said plural cordless terminal devices include one or more of a cordless conductive loop sensor, a cordless smoke detector, a cordless carbon monoxide sensor, a cordless motion detector, and a cordless glass breakage sensor.

11. The system of claim 1, further comprising a cordless remote keypad terminal device having:

a keypad, and

a processor coupled to said keypad, and operable to process security system commands entered via said keypad, and to output said security systems commands encoded within cordless data packets to said cordless local area network.

12. The system of claim 1, wherein said wireless node further comprises:

a metallic telephone line interface coupled to said controller, and wherein

said controller is operable to couple telephone calls between said metallic telephone line interface and said cordless transceiver, thereby enabling access to the public switched telephone network through said cordless local area network.

13. The system of claim 1, wherein said wireless node further comprises:

a subscriber identity module interface adapted to accept subscriber identity modules having user wireless account identities and data stored therein coupled to said controller, and wherein

said controller is operable to transfer user account identity data from said subscriber identity module interface to the wireless telephone network.

14. A method of implementing a cordless security system coupled to a wireless telephone network through a wireless node, the wireless node having a cordless transceiver adapted to communicate cordless signals, according to a cordless local area network protocol, with plural cordless terminal devices, which includes a cordless security sensor terminal device and a cordless security control panel terminal device, the method comprising the steps of:

communicating a cordless sensor signal encoded within a cordless data packet from the cordless security sensor terminal device into the cordless local area network upon receipt of an external stimulus;

routing said cordless sensor signal by the wireless mode to the cordless security control panel terminal device;

communicating a cordless alarm signal encoded within a cordless data packet, by the cordless security control panel terminal device, into said cordless local area network upon receipt of said cordless sensor signal;

transmitting a cordless outgoing audio message, by the a cordless security control panel terminal device, into the cordless local area network;

routing the cordless outgoing audio message through the wireless telephone network to a predetermined telephone number as a wireless telephone call.

15. The method of claim 14, further comprising the steps of:

coupling a telephone call from a cordless telephone terminal device into the wireless telephone network by;

communicating cordless signals, including cordless audio signals, within the cordless local area network, and

enabling telephone communications through said wireless node and into the wireless telephone network.

16. The method of claim 14 further comprising the step of routing the cordless outgoing audio message to a cordless telephone terminal device.

17. The method of claim 14, further comprising the step of activating an alarm output of a cordless security alarm terminal device upon receipt of said cordless alarm signal.

18. The method of claim 17, wherein the cordless security alarm terminal device is a cordless siren or a cordless alarm output receiver.

19. The method of claim 14, further comprising the step of uniquely addressing the cordless data packet portions.

20. The method of claim 14 further comprising the step of uniquely addressing the cordless data packet portions a source and destination cordless terminal device identifier.

21. The method of claim 14, further comprising the steps of pre-recording and storing the cordless outgoing audio message.

22. The method of claim 14, wherein the plural cordless terminal devices include one or more of a cordless conductive loop sensor, a cordless smoke detector, a cordless carbon monoxide sensor, a cordless motion detector, and a cordless glass breakage sensor.
