Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Currently, the SIM card is dropped in general in the following situations: 1) the mobile phone is dropped or collided, so that the card support is displaced, the electrical contact of the SIM card is displaced, and the SIM card cannot normally communicate with the baseband chip. The dropped card in this case belongs to a dropped card in the aspect of hardware structure, and can be manually recovered only by a user. 2) Due to the interference of the electrical signals, the SIM card cannot normally communicate with the baseband chip within a specified time, and finally the card is dropped. The SIM card dropping method for solving the problem has the characteristics that a user can restart the mobile phone after dropping the card, and can try to restart for many times if the mobile phone is abnormal after being restarted until the SIM card and the mobile phone can work normally, but the method consumes a long time, and the communication of the user is easily influenced when the SIM card drops in an emergency, so that the inconvenience is brought to the user.
In order to solve the above problem, in this embodiment, when it is detected that the SIM card is in the card dropping state, the SIM card may be subjected to a normal recovery operation, where the normal recovery operation includes an operation of powering down and then powering up the SIM card at a time when the SIM card is detected to be in the card dropping state; detecting a state of the SIM card after each of the normal recovery operations; after the conventional recovery operation is performed for M times, when the state of the SIM card is detected to be a card dropping state, performing enhanced recovery operation on the SIM card, wherein the enhanced recovery operation comprises the operation of starting timing from the detection that the state of the SIM card is the card dropping state, and powering off and then powering on the SIM card after a preset time period; after each enhanced recovery operation, detecting the state of the SIM card until the state of the SIM card is detected to be a normal state; wherein M is an integer greater than or equal to 1. Therefore, the user terminal can be quickly restored to a normal working state from the SIM card-dropping state, the user does not find that the mobile phone has the card-dropping problem, and the user experience is improved; in addition, the enhanced recovery operation is performed after the conventional recovery operation is performed for M times, so that the power-on and power-off frequency of the SIM card can be reduced, and the SIM card is prevented from being burnt by frequent power-on and power-off.
Fig. 1 is a flowchart illustrating a method for recovering a SIM card lost according to an exemplary embodiment, where as shown in fig. 1, the method for recovering a SIM card lost is used in a terminal, and includes the following steps 101 and 104:
in step 101, when it is detected that the SIM card is in the card-dropping state, performing a normal recovery operation on the SIM card, where the normal recovery operation includes an operation of powering down and then powering up the SIM card at a time when it is detected that the SIM card is in the card-dropping state.
In step 102, the state of the SIM card is detected after each of the normal recovery operations.
In step 103, after M times of the normal recovery operations are performed, when it is still detected that the state of the SIM card is the card-off state, performing enhanced recovery operations on the SIM card, where the enhanced recovery operations include starting timing from the detection that the state of the SIM card is the card-off state, and after a preset time period, performing power-off and then power-on operations on the SIM card.
In step 104, after each enhanced recovery operation, detecting the state of the SIM card until detecting that the state of the SIM card is a normal state.
Wherein M and N are integers greater than or equal to 1.
Here, when the terminal detects that the SIM card cannot normally communicate with the baseband chip, it detects that the SIM card is in a card dropping state, and since the card dropping state is probably caused by interference of an electrical signal, and the card dropping caused by the interference of the electrical signal has the characteristics of burstiness and quick disappearance of the interference, the terminal can perform a conventional recovery operation on the SIM card at this time, that is, the terminal immediately performs a power-off operation on the SIM card at the time of detecting that the SIM card is in the card dropping state, and then performs a power-on operation.
Here, after the terminal performs the above-mentioned normal recovery operation, it needs to detect the state of the SIM card to determine whether the normal recovery operation allows the SIM card to recover to the normal state, and if there is no interference of an electrical signal after power-on, the terminal may detect that the state of the SIM card after power-on recovers to the normal state, and may perform normal communication with the baseband chip, which indicates that this normal recovery operation allows the SIM card to recover to the normal state; if the interference of the electrical signal still exists after the power-on, the terminal can detect that the SIM card still cannot normally communicate with the baseband chip after the power-on, and the state of the SIM card is still in a card-dropping state, which indicates that the SIM card is not restored to the normal state by the conventional restoring operation.
Here, if the current normal recovery operation does not recover the SIM card to a normal state, the terminal will cyclically perform steps 101 and 102, perform the normal recovery operation on the SIM card, and detect the state of the SIM card after each normal recovery operation, and if the terminal performs M times of normal recovery operations, detect that the state of the SIM card is a card-off state after each normal recovery operation, which indicates that interference of electrical signals in this period of time is present all the time, at this time, to avoid the SIM card being burned off by a continuous powering-down and powering-up operation, the terminal may perform an enhanced recovery operation on the SIM card, that is, to start timing from the detection that the state of the SIM card is the card-off state, and perform powering-down and then powering-up operations on the SIM card after a preset time period; therefore, the power-off and power-on operations are carried out at intervals of the preset time period, so that the SIM card can be prevented from being burnt by frequent power-off and power-on operations. It should be noted that the preset time period is not too long to avoid the user from noticing that the SIM card is dropped from the terminal, and is not too short to avoid the power-down and power-up operations being too frequent, for example, the preset time period may be between 3S and 60S.
Here, after the terminal performs the enhanced recovery operation, it needs to detect the state of the SIM card to determine whether the enhanced recovery operation allows the SIM card to recover to the normal state, and if there is no interference of an electrical signal after power-on, the terminal may detect that the state of the SIM card after power-on recovers to the normal state, and may perform normal communication with the baseband chip, which indicates that this enhanced recovery operation allows the SIM card to recover to the normal state; if the interference of the electrical signal still exists after the power-on, the terminal can detect that the SIM card still cannot normally communicate with the baseband chip after the power-on, and the state of the SIM card is still in a card-dropping state, which indicates that the enhanced recovery operation does not recover the SIM card to a normal state.
Here, if the enhanced recovery operation does not recover the SIM card to the normal state, the terminal will loop to steps 103 and 104, perform the enhanced recovery operation on the SIM card, and detect the state of the SIM card after each enhanced recovery operation, and if it is detected that the state of the SIM card is the normal state, the SIM card is dropped and recovered this time, and this flow ends.
Here, in this embodiment, the manner of detecting the state of the SIM card may be that the baseband chip sends a state query instruction to the SIM card, if the baseband chip receives a normal response returned by the SIM card, it is detected that the SIM card is in a normal state, and if the baseband chip does not receive a normal response returned by the SIM card, it is detected that the SIM card is in a card dropping state.
It should be noted that M is a preset integer value, and a value range of M may include an integer less than or equal to 10. The M is not easy to be too large so as to avoid burning the SIM card for too many times of power-off and power-on operations, and meanwhile, the M is also not easy to be too small so as to avoid the situation that the state of the SIM card cannot be recovered due to too few power-off and power-on operations; illustratively, the value of M may range from 5 to 10.
In this embodiment, when it is detected that the SIM card is in the card dropping state, a conventional recovery operation may be performed on the SIM card, where the conventional recovery operation includes an operation of powering down and then powering up the SIM card at a time when it is detected that the SIM card is in the card dropping state; detecting a state of the SIM card after each of the normal recovery operations; after the conventional recovery operation is performed for M times, when the state of the SIM card is detected to be a card dropping state, performing enhanced recovery operation on the SIM card, wherein the enhanced recovery operation comprises the operation of starting timing from the detection that the state of the SIM card is the card dropping state, and powering off and then powering on the SIM card after a preset time period; after each enhanced recovery operation, detecting the state of the SIM card until the state of the SIM card is detected to be a normal state; wherein M is an integer greater than or equal to 1. Therefore, the user terminal can be quickly restored to a normal working state from the SIM card-dropping state, the user does not find that the mobile phone has the card-dropping problem, and the user experience is improved; in addition, the enhanced recovery operation is performed after the conventional recovery operation is performed for M times, so that the power-on and power-off frequency of the SIM card can be reduced, and the SIM card is prevented from being burnt by frequent power-on and power-off.
In a possible implementation manner, in the SIM card drop recovery method, a preset time period of an enhanced recovery operation performed on the SIM card this time is greater than a preset time period of an enhanced recovery operation performed on the SIM card last time.
Here, when the terminal detects that the state of the SIM card is the card dropping state, and after N times of normal recovery operations, it still detects that the state of the SIM card is not recovered, the terminal may start to perform i (where i may be 1, 2, 3 … …) times of enhanced recovery operations on the SIM card, start timing from detecting that the state of the SIM card is the card dropping state, and perform operations of powering off and then powering on the SIM card after a preset time period Ti of the i times of enhanced recovery operations; after the ith enhanced recovery operation, when the state of the SIM card is detected to be a normal state, the process is ended; when the SIM card is detected to be in the card dropping state, the enhanced recovery operation of the (i + 1) th time is carried out on the SIM card, timing is started when the SIM card is detected to be in the card dropping state, and after the preset time period Ti +1 of the enhanced recovery operation of the (i + 1) th time, the SIM card is powered off and then powered on.
For example, when performing enhanced recovery operation, the terminal may start a back-off timer, and the back-off time base of the back-off timer at the first enhanced recovery operation is set to 5 seconds; after 5 seconds, carrying out power-off and power-on operations; if the recovery is successful, the recovery of the SIM card is completed; and when the recovery is unsuccessful, the back-off time of the back-off timer is added by 5 seconds on the basis of the back-off time of the last time, namely, the timing time of each back-off timer is increased by 5 seconds compared with the last time. At this time, the back-off time of the second enhanced recovery operation is 10 seconds, when 10 seconds arrive, the power-off and power-on operations are performed again, and recovery is completed if the operation is successful. Unsuccessful, the back-off time of the back-off timer for the third enhanced recovery operation continues to increment by 5 seconds, 15 s. In this way, the preset time period of the enhanced recovery operation performed on the SIM card at this time is increased by 5 seconds compared with the preset time period of the enhanced recovery operation performed on the SIM card at the last time, and the enhanced recovery operation is performed in a circulating manner until the state of the SIM card is successfully recovered.
In this embodiment, the preset time period of the enhanced recovery operation performed on the SIM card at this time is longer than the preset time period of the enhanced recovery operation performed on the SIM card at the last time, so that the number of power-off and power-on operations in unit time is reduced, and the SIM card is prevented from being burned off due to too frequent power-off and power-on operations.
In a possible embodiment, the SIM card loss recovery method may further include the following step a 1.
In step a1, after detecting that the state of the SIM card is a normal state after one of the M times of normal recovery operations, stopping the subsequent normal recovery operations.
Here, the terminal may cyclically perform steps 101 and 102, perform a normal recovery operation on the SIM card when detecting that the SIM card is in the card dropping state, and detect the state of the SIM card after each normal recovery operation, if the terminal detects that the state of the SIM card is in the normal state after performing the mth (M is less than or equal to M) normal recovery operation, it indicates that the card dropping of the SIM card is recovered, and the SIM card may perform normal communication with the baseband chip, and at this time, may end the process, and stop the subsequent normal recovery operation.
In a possible embodiment, the SIM card loss recovery method may further include the following step a 2.
In step a2, after the number of times of performing the enhanced recovery operation exceeds N times, when it is still detected that the state of the SIM card is the card dropping state, the enhanced recovery operation is stopped, and a prompt message is output, where the prompt message is used to prompt a user that the SIM card has dropped, and N is an integer greater than or equal to 1.
Here, if the terminal performs N enhanced recovery operations, and detects that the states of the SIM card are card dropping states after each enhanced recovery operation, it indicates that the power-down and power-up operations have failed to solve the card dropping problem, the terminal may not try to recover the SIM card any more to prevent the SIM card from being burned off by power-up and power-down, at this time, the terminal may notify an upper layer, output prompt information, for example, display the prompt information on a screen, pop up a prompt window to notify the user that the SIM card is dropped, and ask the user to manually pull the card and then reinsert the card to recover the state of the SIM card.
Here, N is a preset integer value, N is not too large to avoid that the SIM card is burned off too many times by powering down and up operations, and M is also not too small to avoid that the state of the SIM card cannot be recovered because the number of powering down and up operations is too small, for example, the value range of N may be an integer less than or equal to 8.
In this embodiment, after the enhanced recovery operation is performed more than N times, the enhanced recovery operation is stopped when the state of the SIM card is still detected as the card drop state, and a prompt message is output, where the prompt message is used to prompt the user that the SIM card has dropped and ask the user to manually unplug the SIM card and then reinsert the SIM card to recover the state of the SIM card, so as to solve the problem of card drop caused by SIM card displacement.
In a possible embodiment, the SIM card-out recovery method may further include the following steps a1 and a 2.
In step a1, when it is detected that the baseband chip sends a status query command to the SIM card within the polling time and does not receive a normal response returned by the SIM card within a first preset time, it is detected that the SIM card is in a card-dropping state.
In step a2, when it is detected that the baseband chip sends data to the SIM card and does not receive a normal response returned by the SIM card within a second preset time in the process of normal interaction between the baseband chip and the SIM card, it is detected that the SIM card is in a card dropping state.
Here, the baseband chip in the terminal may periodically detect the state of the SIM card, issue a STATUS query command, i.e., a "STATUS" APDU (Application Protocol data unit) command, to the SIM card within a period time of the polling time, and if the SIM card is dropped, the SIM card cannot reply a normal response to the STATUS query command within a first preset time, and at this time, the terminal may detect that the SIM card is in a card dropping state. If the SIM card is normal, a normal response to the status query command may be replied within a first preset time, and at this time, the terminal may detect that the SIM card is in a normal status.
Here, in the process of normal interaction between the baseband chip and the SIM card, the baseband chip may also send some data to the SIM card, after the SIM card receives the data, if the SIM card is in a normal state, a normal response may be sent to the baseband chip, and if the SIM card is in a card-dropping state, the SIM card may not return a normal response to the baseband chip; therefore, if the baseband chip does not receive the normal response returned by the SIM card within the second preset time, the terminal detects that the SIM card is in the card-dropping state.
The embodiment can periodically detect the state of the SIM card and detect the state of the SIM card in the process of normal interaction between the baseband chip and the SIM card, and the detection modes are various.
The implementation is described in detail below by way of several embodiments.
Fig. 2 is a flowchart illustrating a method for recovering a SIM card lost according to an exemplary embodiment, where as shown in fig. 2, the method for recovering a SIM card lost can be implemented by a terminal or the like, and includes steps 201 and 206.
In step 201, when it is detected that the baseband chip sends a status query command to the SIM card within the polling time and does not receive a normal response returned by the SIM card within a first preset time, it is detected that the SIM card is in a card-dropping state.
In step 202, when it is detected that the baseband chip sends data to the SIM card and does not receive a normal response returned by the SIM card within a second preset time in the process of normal interaction between the baseband chip and the SIM card, it is detected that the SIM card is in a card-dropping state.
In step 203, when it is detected that the SIM card is in the card-dropping state, performing a normal recovery operation on the SIM card, where the normal recovery operation includes an operation of powering down and then powering up the SIM card at the time when it is detected that the SIM card is in the card-dropping state.
In step 204, after each of the normal recovery operations, the state of the SIM card is detected.
In step 205, after the M times of normal recovery operations are performed, when it is detected that the state of the SIM card is the card drop state, enhanced recovery operations are performed on the SIM card, or when it is detected that the state of the SIM card is the normal state after one time of normal recovery operations in the M times of normal recovery operations, the subsequent normal recovery operations are stopped, and the process ends.
The enhanced recovery operation comprises the steps of starting timing from the state of detecting the SIM card to be in a card-off state, and powering down and then powering up the SIM card after a preset time period. The value range of M comprises an integer less than or equal to 10, and the preset time period of the enhanced recovery operation performed on the SIM card at this time is longer than the preset time period of the enhanced recovery operation performed on the SIM card at the last time.
In step 206, after each enhanced recovery operation, detecting the state of the SIM card, stopping performing the enhanced recovery operation and outputting a prompt message when the state of the SIM card is still detected to be the card-out state after the number of times of performing the enhanced recovery operation exceeds N times, or ending the process when the state of the SIM card is detected to be the normal state after one enhanced recovery operation among the N enhanced recovery operations.
The prompt information is used for prompting a user that the SIM card is lost, and N is an integer greater than or equal to 1.
The following are embodiments of the disclosed apparatus that may be used to perform embodiments of the disclosed methods.
