Preferred embodiment of the invention

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

Embodiment 1

The embodiment relates to a lock unlocking process when a mobile terminal enters a trusted cell. As shown in FIG. 1 , the lock unlocking method based on the CGI in this embodiment includes:

Step 110: The mobile terminal acquires CGI information of the currently accessed cell, and compares the obtained CGI information with the saved CGI information of the trusted cell.

The mobile terminal of the present invention includes, but is not limited to, a mobile phone. The mobile terminal can acquire the CGI information of the current cell when the mobile terminal detects the handover of the connected cell.

The CGI information of the trusted cell saved by the mobile terminal may be obtained by the following steps: the mobile terminal sets the CGI information of the currently accessed cell according to an instruction input by the user to set the current cell as a trusted cell. The CGI information is saved as a trusted cell. Specifically, the mobile terminal may prompt the user whether to set the current cell as a trusted cell, and the user may set the current cell as a trusted cell according to the prompt or initiative. After the setting, the mobile terminal saves the CGI of the current cell as the CGI of the trusted cell. The CGI of the trusted cell that the mobile terminal sets to save may have one or more, and the user may also delete the CGI information of the previously set trusted cell.

In another embodiment, the user may also query the CGI information of the cell through the mobile terminal. For example, in the Android system, for the GSM network, the mobile terminal may obtain the CGI information and display by: listening to the PhoneStateListener and rewriting the onCellLocationChanged function. First, obtain the MCC and MNC through the TelephonyManager, then obtain the LAC and CID from the location variable, and connect the four values of MCC, MNC, LAC, and CID together as the CGI value. The user can also obtain the CGI information of the cell through other means such as the telecommunication department, and the like. After learning the CGI information of the cell, the user may directly input and save the CGI information of one or more trusted cells in the mobile terminal.

Step 120: The mobile terminal determines that the acquired CGI information is consistent with the CGI information of the trusted cell.

Because this embodiment is a scenario in which the mobile terminal enters the trusted cell, the mobile terminal determines that the acquired CGI information is consistent with the CGI information of the trusted cell.

In step 130, the mobile terminal determines whether the automatic locking function is in an active state, and if so, proceeds to step 140, and if not, ends.

The above locking function may be a screen locking function, which may be a locking function of all or part of an application that can be locked on the mobile terminal, and may also include the above two types of locking functions.

The auto lock function is activated. For example, if the user sets the screen lock function and/or the application lock function to the on state, and the auto lock function is activated, there may be corresponding parameter configuration, such as how much time to automatically lock in standby mode.

Step 140: The mobile terminal blocks the automatic locking function.

The automatic lock function is blocked, and the activation state and corresponding parameters of the automatic lock function set by the user are retained, but the automatic lock is not performed. In this way, when the mobile terminal enters the non-trusted cell, the masking is cancelled, and the automatic locking is performed according to the activated automatic locking function.

Through the above process, when the mobile terminal enters the trusted cell, the automatic locking function can be shielded, and the user does not have to perform the unlocking operation frequently when using the mobile terminal, and the operation is more convenient. , greatly improved the user experience. In addition, the global uniqueness of the CGI can also ensure that the CGI is not recognized as a misidentification of the trusted cell and thus poses a security risk when the CGI is used as the identification information of the cell.

Optionally, after step 130, the mobile terminal further determines the current screen and/or the application. Whether it is locked, the current screen and/or the application are unlocked. This allows the user to unlock the operation and is more convenient for the user.

Optionally, after step 130, the mobile terminal further masks the manual locking function. In a trusted cell, some users may prefer to allow the manual locking function. Some users may manually lock in order to prevent the user from being unclear that the current cell is a trusted cell, which may cause operational inconvenience, and may also tend to not allow manual locking. Therefore, the manual locking function is shielded in the trusted cell as an alternative to the present invention.

Embodiment 2

The embodiment relates to a lock unlocking process when a mobile terminal enters a non-trusted cell. As shown in FIG. 2, the lock unlocking method based on the CGI in this embodiment includes:

Step 210: The mobile terminal acquires CGI information of the currently accessed cell, and compares the obtained CGI information with the saved CGI information of the trusted cell.

This step is the same as step 110.

Step 220: The mobile terminal determines that the acquired CGI information is inconsistent with the CGI information of the trusted cell.

Because this embodiment is a scenario in which the mobile terminal enters the non-trusted cell, the mobile terminal determines that the acquired CGI information is inconsistent with the CGI information of the trusted cell.

Step 230: The mobile terminal determines whether the automatic locking function is blocked, and if so, proceeds to step 240, and if not, ends.

In step 240, the mobile terminal cancels the shielding of the automatic locking function.

Through the above process, when the mobile terminal enters the non-trusted cell, the automatic locking function can be cancelled to meet the requirements of security and the like. That is, different lock unlocking functions can be provided for different areas, and the implementation is simple and convenient.

In addition, if the manual lock function is blocked when the mobile terminal enters the trusted cell, after step 230, the mobile terminal cancels the masking of the manual lock function.

Includes screen lock feature and/or application lock feature.

Optionally, the lock unlocking module 30 is further configured to: when the comparison result is that the acquired CGI information is consistent with the CGI information of the trusted cell, further determine whether the current screen and/or the application is locked, if , unlock the current screen and / or the application.

Optionally, the lock unlocking module 30 is further configured to cancel the shielding of the automatic locking function when the acquired CGI information is inconsistent with the CGI information of the trusted cell and the automatic locking function is blocked.

Optionally, the lock unlocking module 30 further shields the manual locking function when the acquired CGI information is consistent with the CGI information of the trusted cell; and the acquired CGI information and the CGI information of the trusted cell. When the inconsistency and manual lock function are masked, the masking of the manual lock function is canceled.

Optionally, the mobile terminal further includes: an information storage module, configured to: save CGI information of the currently accessed cell as CGI information of the trusted cell according to an instruction input by the user to set the current cell as a trusted cell .
