Abstract

The present invention provides a method for user control of a gateway in a wireless data communicator network. The present invention includes transmitting a data packet to the gateway, including control data continuing a plurality of commands to be executed by the gateway. The gateway then parses the plurality of commands and executes the commands.

Claims

1. A method of remote control by a user of a gateway that forms a bridge between different data networks, said gateway converting received data from one data network protocol to another, the method comprising the steps of:

storing, within the gateway, one or more commands which may be invoked remotely by the user, said commands causing a data exchange between the gateway and a remote system connected to one of the data networks;

transmitting via one of the data networks at least one data packet from data terminal equipment operated by the user to the gateway, wherein at least one data packet includes control data containing information directing the gateway to execute one or more commands on behalf of the user;

validating that each of the one or more commands to be executed on behalf of the user is stored within the gateway; and

executing each command that is validated in the validating step.

2. The method of claim 1, wherein the method further includes a step of transmitting to the user via the gateway a response to each command executed in the executing step, said response originating from either the gateway or the remote system connected to one of the data networks.

3. The method of claim 1, wherein such method further includes a step of treating data requesting a connection with the gateway as control data containing the information directing the gateway to execute one or more commands on behalf of the user, said commands establishing a connection via the gateway to the remote system.

4. The method of claim 1, wherein such method further includes a step of directing control data from the gateway to data communications equipment that is connected to the remote system, said control data altering the operational parameters of said data communications equipment.

5. The method of claim 1, wherein the step of executing each command that is validated in the validating step includes executing at least one command that creates a connection between the remote computer system and the gateway.

6. The method of claim 1, wherein the step of executing each command that is validated in the validating step includes a step of providing a communication script for filtering out unnecessary data received by the gateway from the remote system from being transmitted to the user.

7. The method of claim 1, wherein the step of executing each command that is validated in the validating step includes a step of establishing and implementing file transfer protocols between the gateway and the remote system connected to one of the data networks.

8. The method of claim 1, wherein the step of executing each command that is validated in the validating step includes a step of executing at least one command to enable the user to initiate at least one of opening, switching between and closing a plurality of connections with multiple remote systems and a step of enabling the user to manage the plurality of connections simultaneously.

9. The method of claim 1, wherein at least one of the communications networks is a wireless data communication network.

10. A method of remote control by a user of a gateway that forms a bridge between different data networks, said gateway converting received data from one data network protocol to another, the method comprising the steps of:

storing, within the gateway, one or more commands which the user may remotely direct be executed;

transmitting via one of the data networks to the gateway at least one data packet from data terminal equipment operated by the user to the gateway, wherein at least one data packet includes control data;

using the gateway to extract from the data packet the control data, said control data including information directing the gateway to execute one or more commands stored in the gateway; and

executing at least one command extracted from the data packet transmitted by the user, thereby changing the operation of the gateway.

11. The method of claim 10, wherein the method further includes a step of transmitting to the user via the gateway a response to each command executed in the executing step, said response originating from either the gateway or a remote system connected to one of the data networks.

12. The method of claim 10, wherein such method further includes a step of treating data requesting a connection with the gateway as control data containing the information directing the gateway to execute one or more commands, said commands establishing a connection via the gateway to a remote system connected to one of the data networks.

13. The method of claim 10, wherein such method further includes a step of directing control data from the gateway to data communications equipment that is connected to one of the data networks and is located remotely from the data terminal equipment, said control data altering the operational parameters of said data communications equipment.

14. The method of claim 10, wherein the step of executing at least one command that is extracted from the data packet transmitted by the user includes executing at least one command that creates a connection between a remote computer system connected to one of said data networks and the gateway.

15. The method of claim 10, wherein the step of executing at least one command that is extracted from the data packet transmitted by the user includes a step of providing a communication script for filtering out unnecessary data received by the gateway from a remote system from being transmitted to the user.

16. The method of claim 10, wherein the step of executing at least one command that is extracted from the data packet transmitted by the user includes a step of establishing and implementing file transfer protocols between the gateway and a remote system connected to one of the data networks.

17. The method of claim 10, wherein the step of executing at least one command that is extracted from the data packet transmitted by the user includes a step of executing at least one command to enable the user to initiate at least one of opening, switching between and closing a plurality of connections with multiple remote systems and a step of enabling the user to manage the plurality of connections simultaneously.

18. The method of claim 10, wherein at least one of the communications networks is a wireless data communication network.
