Automatic remote communication using network telephony
View Patent ↗The present invention is a method and apparatus to provide remote communication using network telephony. In a transmitter, an activation message is decoded to generate an activation command. The activation message is sent from an activator via a communication medium in response to a telephony call. An information message is transmitted, responsive to the activation command, to a receiver using a communication protocol. In a receiver, an activation message is decoded to generate an activation command. The activation message is sent in response to a telephone call. An information message is received, responsive to the activation command. The information message is sent from a transmitter according to a communication protocol via a communication medium.
1. A network comprising:
a plurality of commonly coupled location transmitters, each transmitter comprising a transmission unit to broadcast a signal modulated from an information message containing respective location information in response to a telephony call; and
a network component capable of sensing at least one of the plurality of transmitters, the network component comprising:
a sensor capable of at least intermittent coupling to a first transmitter of the plurality of transmitters to receive the respective location information broadcast by the first transmitter, a location determination unit coupled to the sensor to process the received respective location information, and a network interface to externally issue the respective location information in accordance with a packet data format;
wherein the transmission unit of a transmitter broadcasts the respective location information responsive to an activation request.
2. The network of claim 1 , wherein the transmission unit of a transmitter broadcasts the respective location information on a substantially periodic basis.
3. The network of claim 1 , wherein the transmission unit of a transmitter broadcasts the respective location information on a substantially continuous basis.
4. The network of claim 1 , wherein at least one of the plurality of transmitters comprises:
a reception unit coupled to the transmission unit of the at least one of the plurality of transmitters, the reception unit to receive the activation request and to notify the transmission unit of such receipt.
5. The network of claim 1 , wherein each transmitter further comprises a reception unit coupled to the transmission unit to receive the activation request and to notify the transmission unit of such receipt; and wherein the reception units of a set of the transmitters receive the activation request at substantially the same time.
6. The network of claim 5 , wherein the set of the transmitters comprises all of the plurality of transmitters in the network.
7. The network of claim 5 , wherein the set of the transmitters comprises less than all of the plurality of transmitters in the network.
8. The network of claim 1 , wherein the transmitters are geographically dispersed to form a distributed location broadcast system.
9. The network of claim 1 , wherein the transmission unit of a transmitter broadcasts respective location information in a format consistent with at least one of an identification tag, an absolute location, and a relative location.
10. The network of claim 1 , further comprising:
a network component capable of coupling to a first transmitter of the plurality of transmitters to receive and process the respective location information broadcast by the first transmitter.
11. The network of claim 1 , further comprising:
a server coupled to the plurality of transmitters to selectively issue the activation request to the plurality of transmitters.
12. The network of claim 1 , further comprising:
a server coupled to the plurality of transmitters to selectively issue the activation request to the plurality of transmitters responsive to a location event; and
a packet network interposing the network interface of the network component and the server, the packet network to bear the packetized, respective location information to said server.
13. The network of claim 12 , wherein the location event is generated by the network component.
14. The network of claim 13 , wherein the location event comprises an emergency call.
15. The network of claim 12 , further comprising an e-commerce transaction processor coupled to the packet network, wherein the location event is generated by the e-commerce transaction processor.
