Method and apparatus for controlling communications terminal and corresponding communications terminal
First Claim
1. A method for controlling a communications terminal, comprising:
- setting, in a communications terminal, authentication information of a subscriber identity module (SIM) change;
monitoring a SIM change broadcast sent by the communications terminal, and setting, after the SIM change broadcast is monitored, the communications terminal to a locked state; and
monitoring input information on the communications terminal, performing first authentication and comparison, by the communications terminal, after the input information is monitored, on the input information and the set authentication information of a SIM change, and performing second authentication after the first authentication succeeds,wherein the second authentication comprises;
displaying a list of options, receiving a selection instruction for the options, determining whether a selected option is the same as a preset correct option, and releasing by the communications terminal, if same, the locked state of the communications terminal, or otherwise, keeping the locked state of the communications terminal;
wherein the method further comprises;
determining, after the SIM change broadcast is monitored and before the communications terminal is set to the locked state, a content parameter of the SIM change broadcast,when the content parameter is null, an incorrect SIM change broadcast is monitored, and the locking module is configured to continue to monitor a SIM change broadcast sent by the communications terminal without setting the communications terminal to the locked state,when the content parameter is not null, a correct SIM change broadcast is monitored, and the locking module is configured to set the communications terminal to the locked state.

7. An apparatus for controlling a communications terminal, comprising:
-
a setting module, configured to set, in a communications terminal, authentication information of a subscriber identity module (SIM) change; a locking module, configured to monitor a SIM change broadcast sent by the communications terminal, and set, after the SIM change broadcast is monitored, the communications terminal to a locked state; and an unlocking module, configured to monitor input information on the communications terminal, perform first authentication and comparison, after the input information is monitored, on the input information and the set authentication information of a SIM change, and perform second authentication after the first authentication succeeds, wherein the setting module is further configured to set a correct option; wherein the second authentication comprises; displaying a list of options, receiving a selection instruction for the options, determining whether a selected option is the same as a preset correct option, and releasing, if same, the locked state of the communications terminal or otherwise, keeping the locked state of the communications terminal; wherein the locking module is further configured to determine, after the SIM change broadcast is monitored and before the communications terminal is set to the locked state, a content parameter of the SIM change broadcast, when the content parameter is null, an incorrect SIM change broadcast is monitored, and the locking module is configured to continue to monitor a SIM change broadcast sent by the communications terminal without setting the communications terminal to the locked state, when the content parameter is not null, a correct SIM change broadcast is monitored, and the locking module is configured to set the communications terminal to the locked state. - View Dependent Claims (8, 9, 10, 11)
