Abstract

A remote wireless device is provided that operates a user interface specific to a particular target application or device. The wireless device receives information regarding the status or operation of the target'"'"'s application, and uses that information to determine what information and controls to present to the remote user. The remote user views information regarding the target application, and makes desired control selections using the available controls. The wireless device generates a message according to the control selections, and transmits the message to the target device. The target device acts responsive to the control message, and updated operational information may be sent to the remote wireless device.

Claims

1. A method for controlling a target device, the method operating on a mobile wireless device, comprising:

operating a target control interface on the mobile wireless device;

presenting target control information at the mobile wireless device;

receiving a control instruction responsive to presenting the target control information;

generating a control message according to the control instruction; and

transmitting wirelessly the control message to an address for the target device.

2. The method according to claim 1, wherein the presenting step further comprises the steps of:

receiving target application status information; and

using the target application status information to present the target control information.

3. The method according to claim 2, wherein the target application status information is selected from the group consisting of:

target device file information;

target device media information;

current display status of the target device; and

current control options available at the target device.

4. The method according to claim 1, further comprising the steps of:

receiving target application status information responsive to transmitting the control message; and

using the target application status information to present the target control information.

5. The method according to claim 1, further comprising the step of receiving the target control interface in a wireless communication.

6. The method according to claim 1, further comprising the step of establishing a trusted communication with the target device.

7. The method according to claim 1, wherein the operating step is initiated responsive to receiving an SMS, MMS, or EMS message or a message at a predefined IP port.

8. The method according to claim 1, wherein the mobile wireless device is a mobile wireless handset operating according to a commercial, military, or governmental air interface.

9. The method according to claim 1, wherein the mobile wireless device is a mobile wireless handset operating according to CDMA, OFDMA, CDMA2000, UMTS, GSM GPRS, EDGE, PHS, or PCS.

10. An article of manufacture having machine readable software for implementing steps comprising:

operating a target control interface on the mobile wireless device;

presenting target control information at the mobile wireless device;

receiving a control instruction responsive to presenting the target control information;

generating a control message according to the control instruction; and

transmitting wirelessly the control message to an address for the target device.

11. A system for controlling the operation of target using a mobile wireless device, comprising:

operating a host process and an application on the target;

operating a client process on the mobile wireless device;

operating an application control interface on the mobile wireless device using the client process;

presenting application control information to a user with the application control interface;

receiving a control instruction from the user responsive to presenting the application control information;

generating a control message according to the control instruction;

receiving wirelessly the control message at the host process on the target; and

using the received control message to implement a control function on the application.

12. The system according to claim 11, wherein the using step includes generating an API instruction to the application operating on the target.

13. The system according to claim 11, wherein the client process starts responsive to receiving an SMS, EMS, or MMS message with a predefined message or receiving a message at a predefined IP port.

14. The system according to claim 11, wherein the presenting step further comprises the steps of:

receiving application status information; and

using the application status information to present the application control information.

15. The system according to claim 14, wherein the application status information is selected from the group consisting of:

target application file information;

target application media information;

current application status; and

current control options available to the application.

16. The system according to claim 11, wherein the application is a file management application, an email application, a presentation application, a media player application, a volume application, or a channel select application.

17. The system according to claim 11, wherein the target is a computer, a television, a digital video recorder, a set top box, a wireless mobile device, or a media player.

19. The system according to claim 11, further comprising a trusted server configured to communicate with the host process and the client process.

20. The system according to claim 19, wherein the host process uses information retrieved from the trusted server to discover the mobile wireless device.

21. The system according to claim 19, wherein the host process uses information retrieved from the trusted server to discover the address and public key for the mobile wireless device.

22. The system according to claim 19, wherein the host process and client process use keys retrieved from the trusted server in an asymmetrical security process to establish trust.

23. The system according to claim 22, wherein the host process and client process use a symmetrical security process for wireless communications after having established trust.

18. The system according to claim 1110, wherein the mobile wireless device is a wireless handset, a wireless PDA, a modem card, a wireless media player, or a dedicated wireless controller.
