Abstract

A method for keeping a scene secret includes the following steps: setting restricted area information containing an identifier of the restricted area, an identifier of a restricted user and a restricted user function in the restricted area; judging whether a mobile phone belongs to the restricted user if determining that the mobile terminal has entered the restricted area, and forbidding the mobile terminal to execute the restricted user function if the mobile phone belongs to the restricted user. A system is used for keeping a scene secret. The method and system prevent the secret of a specific scene from being transmitted outside though a specific function of a mobile terminal.

Claims

1. A method for keeping a scene secret, comprising:

setting restricted area information containing an identifier of the restricted area, an identifier of a restricted user and a restricted user function in the restricted area;

judging whether a mobile phone belongs to the restricted user if determining that the mobile terminal has entered the restricted area, and forbidding the mobile terminal to execute the restricted user function if the mobile phone belongs to the restricted user.

2. The method of claim 1, wherein said judging whether the mobile terminal has entered the restricted area comprises:

sending a registration request to the network side after the mobile terminal is turned on;

registering the mobile terminal and starting a location positioning system to trace the mobile terminal upon receiving the registration request;

judging whether the location of the mobile terminal belongs to the area corresponding to the identifier of the restricted area, if yes, determining that the mobile phone has entered the restricted area;

otherwise, determining that the mobile phone is out of the restricted area.

3. The method of claim 2, wherein the registration request sent by the mobile terminal contains user capability information, the method further comprising:

determining a user function to be forbidden using the user capability information and the restricted area information.

4. The method of claim 1, wherein the restricted area information is stored in the mobile terminal;

and

said judging whether the mobile terminal has entered the restricted area comprises;

broadcasting the restricted area information in the restricted area;

judging whether the restricted area information is same as that saved in the mobile terminal upon entering the restricted area and receiving the broadcasted information;

if the two are the same, determining that the mobile terminal has entered the restricted area;

otherwise, determine that the mobile terminal is out of the restricted area.

5. The method of claim 1, further comprising:

setting a positioning enabling parameter;

broadcasting the restricted area information and the positioning enabling parameter in the restricted area;

wherein said judging whether the mobile terminal has entered the restricted area comprises;

sending a location information request to the network side using the received positioning enabling parameter upon receiving the broadcasted information;

judging whether the location of the mobile terminal is in the restricted area according to the received restricted area information upon receiving the location information of the mobile terminal sent by the network side, if it is in the restricted area, disabling the restricted user function of the mobile terminal on its own initiative.

6. The method of claim 1, wherein said forbidding the mobile terminal to execute the restricted user function comprises:

sending a communication forbidding notification containing the restricted user function of the mobile terminal to the mobile terminal;

disabling the corresponding user function according to the restricted user function in the communication forbidding notification upon receiving the communication forbidding notification.

7. The method of claim 1, wherein the restricted user function comprises a function of communication;

and

said forbidding the mobile terminal to execute the restricted user function comprises;

forbidding the communication by building no connection for the user or refusing to transmit an information flow.

8. The method of claim 1, wherein the restricted user function comprises a function of camera shooting and/or a function of recording, the method further comprising:

sending a function forbidding notification to the mobile terminal;

disabling the restricted user function.

9. The method of claim 1, wherein the restricted user function comprises at least one of functions of camera shooting, recording, answering a phone call and sending a connection request.

10. The method of claim 1, wherein the restricted user function is determined by restriction levels.

11. A system for keeping a scene secret, comprising:

a mobile communication network with a positioning system, for storing restricted area information containing an identifier of the restricted area, an identifier of a restricted user and a user function restricted in the restricted area;

when a mobile terminal is turned on, the mobile communication network starts the positioning system to trace the mobile terminal, and disables the mobile terminal to execute the restricted user function when determining that the mobile terminal is located in the restricted area according to the restricted area information stored in the mobile communication network.

12. A system for keeping a scene secret, comprising:

a mobile communication network, for broadcasting restricted area information comprising containing an identifier of the restricted area, an identifier of a restricted user in the restricted area and a restricted user function in the restricted area;

a mobile terminal, for storing the restricted area information, judging whether the received restricted area information is same as that stored in the mobile terminal upon entering the area and receiving the broadcasted information, and stopping the restricted user function if the two are the same.

13. A system for keeping a scene secret, comprising:

a mobile communication network, for broadcasting in real time a positioning enabling parameter and restricted area information which contains an identifier of the restricted area, an identifier of a restricted user in the restricted area and a restricted user function; and

providing location information for a mobile terminal according to the positioning enabling parameter sent by the mobile terminal;

a mobile terminal, for acquiring the location information of the mobile terminal from the mobile communication network by using the positioning enabling parameter received, judging whether the location is in the restricted area according to the received restricted area information, and stopping the user function when determining that the mobile terminal is in the restricted area.
