Abstract

A remote control method may include: sending a control privilege request message to a control privilege manager; receiving, by an agent, a control privilege response message corresponding to the control privilege request message; and transitioning from a passive mode during which the agent is remotely controlled by an external device to an active mode during which the agent remotely controls an external device.

Claims

1. A method comprising:

sending a control privilege request message to a control privilege manager;

receiving, by an agent, a control privilege response message corresponding to the control privilege request message; and

transitioning from a passive mode during which the agent is remotely controlled by an external device to an active mode during which the agent remotely controls an external device.

2. The method of claim 1, wherein the transitioning from the passive mode to the active mode is performed when a control privilege grant indication is present in the control privilege response message.

3. The method of claim 1, further comprising:

receiving, by the agent included in a terminal, user input information.

4. The method of claim 3, wherein the user input information is one of voice data, touch data, and image data.

5. The method of claim 3, wherein, when the user input information is the voice data, the sending the control privilege request message is performed after a user of the voice data is recognized.

6. The method of claim 1, wherein the sending the control privilege request message comprises:

transmitting the control privilege request message containing reference information comprising at least one of terminal characteristic information, terminal state information, user input information, requested function information indicating a user requested function, and user identification (ID).

7. The method of claim 1, wherein the agent operates in the active mode and the method further comprises:

detecting, by the agent, a privilege transfer event;

sending, upon detection of the privilege transfer event, a privilege transfer request message to the control privilege manager; and

transitioning, by the agent, from the active mode to a wait mode, during which the agent is remotely controlled by the external device and is permitted to re-request the control privilege.

8. The method of claim 1, further comprising:

entering, by the agent, the passive mode during which the agent executes a function of a terminal under remote control of the external device or a wait mode during which the agent is remotely controlled by the external device and is permitted to re-request the control privilege, when a control privilege grant indication is absent in the control privilege response message.

9. The method of claim 8, wherein the control privilege response message comprises a candidate indication for the control privilege and the method further comprises:

entering, by the agent, the wait mode;

detecting, by the agent operating in the wait mode, a privilege re-request event; and

sending, upon detection of the privilege re-request event, a control privilege re-request message to the control privilege manager.

10. A method comprising:

receiving request messages for a control privilege enabling remote control of an external device from at least two agents included in a terminal and in the external device;

determining to grant the control privilege to at least one of the at least two agents based on reference information contained in the request messages; and

sending a response message containing a control privilege grant indication to the agent determined to receive the control privilege.

11. The method of claim 10, wherein the determining to grant the control privilege comprises:

selecting one or more candidates from the at least two agents based on user input information contained in the reference information; and

determining to grant the control privilege to one of the one or more candidates.

12. The method of claim 11, wherein the selecting comprises selecting one or more agents, which received voice data as user input information, as the one or more candidates, respectively.

13. The method of claim 11, wherein the determining to grant the control privilege comprises granting the control privilege to the candidate with a highest signal-to-noise ratio (SNR) for the voice data, if more than one candidate is selected.

14. The method of claim 11, wherein multiple candidates are selected and the determining to grant the control privilege comprises:

representing reference information of each of the candidates as a numerical score; and

granting the control privilege to the candidate with the highest score.

15. A terminal comprising:

a wireless communicator configured to communicate with an external device; and

a controller configured to control the wireless communicator,

wherein the controller is configured to control the wireless communicator to send a control privilege request message and to receive a control privilege response message corresponding to the control privilege request message, and transitions, from a passive mode during which the controller is remotely controlled by an external device to an active mode during which the controller remotely controls the external device when a control privilege grant indication is present in the control privilege response message.

16. The terminal of claim 15, further comprising a user interface interacting with a user,

wherein the controller is configured to control the user interface.

17. The terminal of claim 16, wherein the controller is configured to control, upon reception of user input information through the user interface, the wireless communicator to send the control privilege request message.

18. The terminal of claim 15, wherein the controller controls, upon detection of a privilege transfer event, the wireless communicator to send a privilege transfer request message, and

transitions from the active mode to a wait mode during which the controller is remotely controlled by the external device and is permitted to re-request the control privilege.

19. The terminal of claim 15, wherein the controller is configured to enter the passive mode during which the controller executes a function of the terminal under remote control of the external device or a wait mode during which the controller is remotely controlled by the external device and is permitted to re-request the control privilege, when a control privilege grant indication is absent in the control privilege response message.

20. The terminal of claim 15, wherein the control privilege response message comprises a candidate indication for the control privilege,

the controller is configured to enter the wait mode, and

the controller is configured to control, upon detection of a privilege re-request event, the wireless communicator to send a control privilege re-request message.

21. A terminal comprising:

a wireless communicator configured to receive request messages for a control privilege for enabling remote control of other devices, from external devices; and

a controller configured to control the wireless communicator,

wherein the controller is configured to determine to grant a control privilege to one of the external devices based on reference information contained in the request messages, and controls the wireless communicator to send a response message containing a control privilege grant indication to the external device determined to receive the control privilege.

22. The terminal of claim 21, wherein the controller selects one or more candidates from the external devices based on user input information contained in the reference information and determines to grant the control privilege to one of the candidates.

23. The terminal of claim 22, wherein multiple candidates are selected,

the controller represents reference information of each of the candidates as a numerical score and determines to grant the control privilege to the candidate with a highest score.

24. A non-transitory storage medium storing program instructions which, when executed a processor of a terminal supporting wireless communication, cause the processor to execute a method comprising:

sending a control privilege request message to a control privilege manager;

receiving, by an agent, a control privilege response message corresponding to the control privilege request message; and

transitioning from a passive mode during which the agent is remotely controlled by an external device to an active mode during which the agent remotely controls an external device.
