Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
Example one
The present embodiment relates to a locking and unlocking process when a mobile terminal enters a trusted cell, and as shown in fig. 1, the locking and unlocking method based on a CGI of the present embodiment includes:
the mobile terminal of the present invention includes, but is not limited to, a cellular phone. The mobile terminal can obtain the CGI information of the current cell when the mobile terminal is started and the connected cell is monitored to be switched.
The CGI information of the trusted cell stored by the mobile terminal may be obtained by the following method before this step: and the mobile terminal saves the CGI information of the current access cell as the CGI information of the trusted cell according to an instruction input by the user for setting the current cell as the trusted cell. Specifically, the mobile terminal may prompt a user whether to set the current cell as a trusted cell, the user may set the current cell as the trusted cell according to the prompt or actively, after the setting, the mobile terminal stores the CGI of the current cell as the CGI of the trusted cell, the CGI of the trusted cell that the mobile terminal sets and stores may be one or more, and the user may also delete the CGI information of the trusted cell that is set before.
In another embodiment, the user may also query the CGI information of the cell through the mobile terminal, for example, in an Android system, for a GSM network, the mobile terminal may obtain the CGI information and display it in the following manner: monitoring PhoneStateListener, rewriting onCellLocationChanged function, firstly obtaining MCC and MNC through TelephonManager, then obtaining LAC and CID through location variable, and connecting the four values of MCC, MNC, LAC and CID together to obtain the CGI value. The user may also be queried to know the CGI information of the cell by other means, such as a telecommunications department, etc. After acquiring the CGI information of the cell, the user can directly input and store the CGI information of one or more trusted cells in the mobile terminal.
since this embodiment is a scenario in which the mobile terminal enters the trusted cell, in this step, the mobile terminal determines that the obtained 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 activated state, if so, the process proceeds to step 140, and if not, the process is ended.
The locking function may be a screen locking function, may be a locking function of all or part of applications that can be locked on the mobile terminal, and may also include the above two types of locking functions.
The automatic locking function is in an activated state, for example, a user sets the screen locking function and/or the application locking function in an opened state, and when the automatic locking function is activated, corresponding parameter configurations may be provided, such as how much time the user waits for automatic locking, and the like.
The shielding automatic locking function is to keep the activation state and corresponding parameters of the automatic locking function set by the user, but not to execute automatic locking. Thus, when the mobile terminal enters an untrusted cell, the shielding can be canceled, and automatic locking can be executed according to the activated automatic locking function.
Through the process, when the mobile terminal enters a trusted cell, the automatic locking function can be shielded, the user does not need to frequently unlock the mobile terminal, and the operation is more convenient. And the user experience is greatly improved. In addition, the global uniqueness of the CGI can also ensure that the CGI is used as the identification information of the cell, so that the trusted cell cannot be mistakenly identified and potential safety hazards are caused.
Optionally, after step 130, the mobile terminal further determines whether the current screen and/or the application program is locked, and unlocks the current screen and/or the application program. Therefore, the user does not need to perform unlocking operation, and the use by the user is more convenient.
Optionally, after step 130, the mobile terminal also masks the manual locking function. In a trusted cell, part of users may prefer to allow the manual locking function, and part of users may prefer not to allow the manual locking function in order to avoid the inconvenience of the user in manually locking the current cell to the trusted cell, and thus, the manual locking function is shielded in the trusted cell as an alternative of the present invention.
Example two
The present embodiment relates to a locking and unlocking process when a mobile terminal enters an untrusted cell, and as shown in fig. 2, the locking and unlocking method based on a CGI of the present embodiment includes:
this step is the same as step 110.
since this embodiment is a scenario in which the mobile terminal enters an untrusted cell, the mobile terminal in this step may determine that the obtained CGI information is not consistent with the CGI information of the trusted cell.
In step 230, the mobile terminal determines whether the automatic locking function is shielded, if so, the process proceeds to step 240, and if not, the process ends.
In step 240, the mobile terminal cancels the shielding of the automatic locking function.
Through the process, when the mobile terminal enters an untrusted cell, the shielding of the automatic locking function can be cancelled, so that the requirements on the aspects of safety and the like are met. Namely, different locking and unlocking functions can be provided for different areas, and the realization is simple and convenient.
In addition, if the mobile terminal blocks the manual locking function when entering a trusted cell, the mobile terminal cancels the blocking of the manual locking function after step 230.

Optionally, the locking and unlocking module 30 is further configured to, when the obtained CGI information is consistent with the CGI information of the trusted cell as a result of the comparison, further determine whether the current screen and/or the application program is locked, and if so, unlock the current screen and/or the application program.
Optionally, the locking and unlocking module 30 is further configured to cancel the shielding of the automatic locking function when the obtained CGI information is inconsistent with the CGI information of the trusted cell and the automatic locking function is shielded.
Optionally, when the obtained CGI information is consistent with the CGI information of the trusted cell, the locking and unlocking module 30 further shields a manual locking function; and when the obtained CGI information is inconsistent with the CGI information of the trusted cell and the manual locking function is shielded, canceling the shielding of the manual locking function.
Optionally, the mobile terminal further includes: and the information storage module is used for storing the CGI information of the current access cell as the CGI information of the trusty cell according to an instruction which is input by a user and used for setting the current cell as the trusty cell.
