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 radio link and performing an operation according to the received control command, the mobile terminal operating based on a layer structure in which a remote control layer exists on a teleservice layer; and

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

wherein the user interface of the remote control emulator provides a fully interactive user interface to a user to control a plurality of functions of the mobile terminal, 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.

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

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

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

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 web emulator operates based on 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 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.

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

(a) driving a mobile terminal web emulator by logging in through a client terminal, the mobile terminal operating based on a layer structure in which a remote control layer exists on a teleservice layer;

(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 a remote control server; and

(d) performing emulation according to a reply received from the remote control server within a prescribed time,

wherein a user interface of the client terminal provides a fully interactive user interface to a user to control a plurality of functions of the mobile terminal, 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 method as claimed in claim 11, 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.

13. 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,

wherein the interactive remote control teleservice provides a fully interactive user interface to a user to control a plurality of functions of the mobile terminal, which operates based on a layer structure in which a remote control layer exists on a teleservice layer; and

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.
