Remote control of functions via wireless transmission of text-based messages
View Patent ↗A remote control device is located in an environment proximate to conditions to be monitored and actions to be implemented. The remote control device is able to receive and transmit wireless text based communications. A user employing a wireless communication device that supports text based messaging can transmit a control message containing a predetermined command to the remote control device. After preferably authenticating the user, the remote control device initiates a predetermined action based on receipt of a corresponding command.
1. A method implemented by remote control device for remotely controlling functions and providing status information comprising the steps of:
storing predetermined text based commands;
receiving a control message transmitted over a wireless communication channel;
parsing the control message to identify a first text based command;
comparing said first text based command with said stored predetermined text based commands to determine if the first text based command is a valid command;
executing a predetermined control action corresponding to said first text based command if the latter is determined to be a valid command;
wherein the step of executing a predetermined control action comprises generating a request for information signal, transmitting the request for information signal to an apparatus external to the remote control device, receiving first status information from the apparatus in response to said request for information signal, and transmitting a reply message containing the first status information in text based format to an address from which the control message was received.
2. The method according to claim 1 wherein the step of executing a predetermined control action comprises generating a control signal and transmitting the control signal to a first function controllable by the control signal.
3. The method according to claim 1 wherein the step of receiving a control message comprises receiving a short messaging system message received over a cellular wireless communication channel.
4. The method according to claim 1 wherein the received control message includes a first text based command and an associated first parameter where the first parameter defines a numeric value that is utilized in determining the control action to be executed.
5. The method according to claim 1 further comprising the step of connecting the remote control device to electronic control means in a vehicle, at least a group of said predetermined text based commands having a corresponding control action associated with an operable function of the vehicle.
6. The method according to claim 1 wherein the remote control device includes a means for generating location coordinates, the step of executing a predetermined control action comprising generating a request for location signal, transmitting the request for location signal to the means for generating location coordinates, receiving first location information from said means in response to said request, and transmitting a reply message containing the first location information in text based format to an address from which the control message was received.
7. The method according to claim 1 further comprising the steps of storing authentication information associated with at least one of a first user and a first user's wireless communication device, and utilizing said at least one to determine whether the received control message is valid.
8. The method according to claim 7 wherein the authentication information associated with the first user'wireless communication device comprises an electronic serial number of said device.
9. The method according to claim 1 wherein the generating of the request for information signal is in response to the receipt of the first text based command, and the first status information received by the remote control device was originated by and transmitted from the apparatus.
10. A method for remotely controlling functions and providing status information comprising the steps of:
storing predetermined text based commands in a remote control device;
transmitting a text based control message addressed to the remote control device from a cellular telephone;
upon receipt of said control message at the remote control device, parsing the control message to identify a first text based command;
determining the validity of the first command based on whether the first command is a match with any of said stored predetermined text based commands;
executing a predetermined control action corresponding to said first text based command by the remote control device upon the first command having been determined to be valid;
wherein the step of executing a predetermined control action comprises generating a request for information signal, transmitting the request for information signal to an apparatus external to the remote control device, receiving first status information from the apparatus in response to said request for information signal, and transmitting a reply message containing the first status information in text based format to the cellular telephone based on an address of the cellular telephone received with the control message.
11. The method according to claim 10 wherein the step of transmitting the control message comprises transmitting a short messaging format message by the cellular telephone, and wherein the step of executing a predetermined control action comprises generating a control signal and transmitting the control signal from the remote control device to an apparatus having a first function controllable by the control signal.
12. The method according to claim 10 wherein the received control message includes a first text based command and an associated first parameter where the first parameter defines a numeric value that is utilized in determining the control action to be executed.
13. The method according to claim 10 further comprising the step of connecting the remote control device to electronic control means in a vehicle, at least a group of said predetermined text based commands having a corresponding control action associated with an operable function of the vehicle.
14. The method according to claim 10 wherein the remote control device includes a means for generating location coordinates, the step of executing a predetermined control action comprising generating a request for location signal, transmitting the request for location signal to the means for generating location coordinates, receiving first location information from said means in response to said request, and transmitting a reply message to the cellular telephone containing the first location information in text based format.
15. The method according to claim 10 further comprising the steps of storing in the remote control device authentication information associated with at least one of a first user and the cellular telephone, and utilizing said at least one to determine whether the received control message is valid.
16. The method according to claim 15 wherein the authentication information associated with the cellular telephone comprises an electronic serial number of the cellular telephone.
17. The method according to claim 10 wherein the generating of the request for information signal is in response to the receipt of the first text based command, and the first status information received by the remote control device was originated by and transmitted from the apparatus.
