Abstract

Disclosed is a system for remotely controlling a mobile terminal in a mobile communication system. The mobile terminal receives a control command through a call link and performs an operation according to the received control command. An Internet service provider including a remote control emulator transmits a mobile terminal remote control command to the mobile terminal through the call link, upon receipt of the mobile terminal remote control command through a user interface of the remote control emulator.

Claims

1. A system for remotely controlling a mobile terminal in a mobile communication system, comprising:

the mobile terminal for receiving a control command through a call link and performing an operation according to the received control command; and

an Internet service provider including a remote control emulator, for transmitting a mobile terminal remote control command to the mobile terminal through the call link upon receipt of the mobile terminal remote control command through a user interface of the remote control emulator.

2. The system as claimed in claim 1, wherein the call link is a voice call link.

3. The system as claimed in claim 1, wherein the call link is an SMS (Short Message Service) call link.

4. The system as claimed in claim 1, wherein the call link is a data call link.

5. The system as claimed in claim 1, wherein the mobile terminal transmits a remote control process result to the Internet service provider through the call link.

6. The system as claimed in claim 1, wherein the user is connected to the Internet service provider through another mobile terminal.

7. The system as claimed in claim 1, wherein the user is connected to the Internet service provider through a computer.

8. The system as claimed in claim 1, wherein the mobile terminal operates based on an IS-637+ layer structure in which a remote control layer exists on a teleservice layer.

9. The system as claimed in claim 8, wherein the remote control layer includes a remote control type field indicating whether a character field of user data of a teleservice layer represents an SMS message or a remote control message, a result code field indicating a remote control process result for the mobile terminal, a security code length field, a security code field indicating whether remote control access to the mobile terminal is available, a remote control parameter length field, and a remote control information parameter field.

10. The system as claimed in claim 1, wherein the web emulator operates based on an IS-637+ layer structure in which a remote control layer exists on a teleservice layer.

11. The system as claimed in claim 10, wherein the remote control layer includes a remote control type field indicating whether a character field of user data of a teleservice layer represents an SMS message or a remote control message, a result code field indicating a remote control process result for the mobile terminal, a security code length field, a security code field indicating whether remote control access to the mobile terminal is available, a remote control parameter length field, and a remote control information parameter field.

12. The system as claimed in claim 1, wherein the mobile terminal includes a remote control application for converting a remote control command or a remote control process result to a user interface signal of the mobile terminal.

13. A method for remotely controlling a mobile terminal through an Internet service provider connected to a mobile communication system providing a short message service, comprising the steps of:

(a) driving an mobile terminal web emulator by logging in through a client terminal;

(b) setting up a call by inputting a phone number of a remote server terminal after driving the mobile terminal web emulator;

(c) outputting a remote control main menu provided by the remote server terminal through the set call and transmitting a remote control command to the remote control server; and

(d) performing emulation according to a reply, upon receipt of the reply from the remote control server within a prescribed time.

14. The method as claimed in claim 13, further comprising the steps of:

determining whether the remote control is completed;

ending the call, when the remote control is completed; and

returning to the step (c), when the remote control is not completed.

15. A mobile terminal comprising:

a user interface having a remote control application which is activated in a remote control client mode when an origination call is connected to an interactive remote control teleservice in an SMS service option, and is activated in a remote control server mode when a call from a network is connected to the interactive remote control teleservice in the SMS service option.
