Technical Field

Background
A Subscriber Identity Module (SIM) card is a Subscriber Identity Module (SIM) card, and a mobile phone must be equipped with the SIM card for communication, and the SIM card is an essential important component in the mobile phone. At present, the SIM card is generally dropped under the following conditions that 1) the card support is displaced due to dropping or collision of the mobile phone, so that the electrical contact of the SIM card is displaced, and finally the SIM card cannot normally communicate with a 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. Because the SIM card dropping caused by the electrical signal interference is sudden, and cannot communicate with the baseband chip in a short time, but the interference disappears quickly, and so on, the SIM card dropping method for solving the reason is usually that the user manually restarts the mobile phone after the SIM card is dropped. If the mobile phone is abnormal after being restarted, the user can try to manually restart the mobile phone for a plurality of times until the SIM card is recovered to a normal state.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminology used in the following embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used in the specification of the present application and the appended claims, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the listed items.
It should be noted that the terms "first," "second," "third," and the like in the description and claims of the present application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in other sequences than described or illustrated herein. Furthermore, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or server that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Some terms of art related to the embodiments of the present application are described below:
one, cold reset operation
After the SIM card contact is activated, the reset (reset) signal is pulled high. The cold reset is the reset of powering on the SIM card again after powering off the SIM card. Therefore, the cold reset operation of the SIM card can also be understood as powering down and then powering up the SIM card.
Second, hot reset operation
The hot reset operation of the SIM card means that a reset signal is sent to the SIM card under the condition that the SIM card is electrified.
Third, timer
Namely, a timing device simulated by software needs to acquire a timestamp a of a current system when a timer is started, then adds a time B to be timed with the timestamp a, and when the system timestamp is greater than a + B, indicates that the timing time is up, and starts to call a callback function to execute corresponding operations.
Fourth, nonvolatile memory (NV)
Once data is written into NV, the data cannot be lost even if power is lost, and the original setting can still be kept when the data is restarted next time.
The method, the apparatus, the chip and the module device for recovering the SIM card provided in the embodiments of the present application are further described in detail below.
Fig. 1 is a schematic flowchart of a SIM card recovery method according to an embodiment of the present application. As shown in fig. 1, the SIM card recovery method includes the following steps 101 and 102. The method execution subject shown in fig. 1 may be a terminal device. Alternatively, the method execution body shown in fig. 1 may be a chip in the terminal device. Fig. 1 illustrates an execution subject of the method by taking a terminal device as an example.
101. And when the terminal equipment detects that the state of the SIM card is the card-dropping state, carrying out hot reset operation on the SIM card.
In the embodiment of the application, the terminal equipment can detect whether the SIM card is dropped by sending an instruction to the SIM card. For example, after the terminal device sends the instruction to the SIM card, if the terminal device does not receive the response of the SIM card within the preset time, the terminal device determines that the SIM card is dropped. Or after the terminal equipment sends the instruction to the SIM card, if the terminal equipment determines that the information returned by the SIM card is abnormal, the terminal equipment determines that the SIM card is lost. After detecting that the SIM card is lost, the terminal equipment carries out hot reset operation on the SIM card, namely the terminal equipment sends a reset signal to the SIM card under the condition that the SIM card is kept powered on.
102. And if the state of the SIM card is still in the card-off state after the hot reset operation is performed on the SIM card for N1 times, the terminal equipment performs a first cold reset operation on the SIM card.
In the embodiment of the application, N1 is greater than or equal to 1.
When N1 is 1, after the terminal device performs the first hot reset operation on the SIM card, if the SIM card is still in the card-off state, the terminal device may perform the cold reset operation on the SIM card.
When N1 is greater than 1, after the terminal device performs the first hot reset operation on the SIM card, if the SIM card is still in the card drop state, the terminal device may perform the hot reset operation on the SIM card again until the SIM card returns to the normal state, or until the number of times of performing the hot reset operation on the SIM card reaches N1 times. For example, N1 is 2, 3, 4, 5, 6, 7, or 8, and the like. If the number of times that the terminal device performs the hot reset operation on the SIM card reaches N1 times, and the SIM card is still in the card-dropping state, the terminal device may perform the cold reset operation on the SIM card.
In one possible implementation, N1 is system preset or user-defined.
It can be seen that, based on the method described in fig. 1, the terminal device may perform a hot reset operation on the SIM card first. If the SIM card is in the card-dropping state after N1 times of hot reset operation, then the SIM card is in cold reset operation. Because the SIM card is not required to be powered off and then powered on in the hot reset operation, the SIM card can be recovered to a normal state in more time by carrying out the hot reset operation on the SIM card.
Fig. 2 is a schematic flowchart of another SIM card recovery method according to an embodiment of the present application. As shown in fig. 2, the SIM card recovery method includes the following steps 201 to 207. The method execution subject shown in fig. 2 may be a terminal device. Alternatively, the method execution body shown in fig. 2 may be a chip in the terminal device. Fig. 2 illustrates an execution subject of the method by taking the terminal device as an example.
201. And when the SIM card is detected to be in the card-dropping state, the terminal equipment carries out hot reset operation on the SIM card.
202. And if the state of the SIM card is still in the card-off state after the hot reset operation is performed on the SIM card for N1 times, the terminal equipment performs a first cold reset operation on the SIM card. Wherein N1 is greater than or equal to 1
For specific implementation of step 201 and step 202, reference may be made to specific implementation of step 101 and step 102, which are not described herein again.
203. And if the state of the SIM card is still in the card dropping state after the first cold reset operation is performed on the SIM card for N2 times, the terminal equipment outputs first prompt information, and the first prompt information is used for prompting the SIM card to drop.
Wherein N2 is greater than or equal to 1. Optionally, N2 is system preset or user-defined.
When N2 is 1, after the terminal device performs a first cold reset operation on the SIM card for one time, the state of the SIM card is still in the card dropping state, and the terminal device outputs first prompt information for prompting that the SIM card drops.
When N2 is greater than 1, after the terminal device performs the first cold reset operation on the SIM card for multiple times, the state of the SIM card is still the card dropping state, and the terminal device outputs first prompt information for prompting the SIM card to drop the card.
Optionally, the terminal device may prompt the SIM card to be dropped by displaying a text or a signal-free icon.
In a possible implementation, if the state of the SIM card is still in the card-out state after N2 times of the first cold reset operation on the SIM card, the terminal device may further output a time for prompting a subsequent automatic recovery operation on the SIM card. For example, the terminal device may prompt the user that a recovery operation will be automatically performed on the SIM card after 20 seconds.
204. If the state of the SIM card is still in the card-dropping state after N2 times of first cold reset operations are performed on the SIM card, the terminal device starts a first reset timer.
205. And the terminal equipment performs second cold reset operation on the SIM card when the first reset timer is overtime.
If the state of the SIM card is still in the card-lost state after N2 times of first cold reset operations, it proves that the SIM card may not be recovered even if the cold reset operation is performed on the SIM card for a short time. In order to save the power consumption of the terminal device, the terminal device may perform a cold reset operation on the SIM card after a preset time. Therefore, it is advantageous to save power consumption of the terminal device by performing step 204 and step 205.
206. And if the state of the SIM card is still in the card-dropping state after the second cold reset operation is carried out on the SIM card, the terminal equipment starts a second reset timer.
207. And when the second reset timer is over time, the terminal equipment performs third cold reset operation on the SIM card.
And the duration of the second reset timer is greater than the duration of the first reset timer. That is, after the first cold reset operation is performed on the SIM card N2 times, the state of the SIM card is still in the card-out state, and the time interval between the subsequent cold reset operations of the terminal device is increasingly larger. This is advantageous in saving power consumption of the terminal device.
In another possible implementation, the duration of the second reset timer may also be equal to the duration of the first reset timer. That is, after the first cold reset operation is performed on the SIM card N2 times, the state of the SIM card is still in the card-out state, and the time interval between the subsequent cold reset operations of the terminal device is equal.
In one possible implementation, if the state of the SIM card is a normal state after the second cold reset operation is performed on the SIM card, the terminal device may prompt the SIM card to return to the normal state. If the state of the SIM card is a normal state after the third cold reset operation is performed on the SIM card, the terminal device may prompt the SIM card to recover to the normal state. Optionally, the terminal device may prompt the SIM card to return to the normal state by displaying a text or an icon with a signal.
In one possible implementation, when the number of cold reset operations performed on the SIM card after N2 times of the first cold reset operation reaches N3 times, if the state of the SIM card is still in the card drop state, the cold reset operation performed on the SIM card is stopped, and second prompt information is output, where the second prompt information is used for prompting the user to insert the SIM card again, and N3 is greater than 1. Optionally, N3 is system preset or user-defined.
When the cold reset operation is performed N3 times after N2 times of the first cold reset operation, it is described that the SIM card is dropped due to the loosening of the SIM card. In this case, therefore, the cold reset operation of the SIM card can be stopped to save power consumption of the terminal device. And the terminal equipment can output second prompt information which is used for prompting the user to insert the SIM card again so that the user can insert the SIM card again in time and restore the SIM card to a normal state in time.
In one possible implementation, the duration of the first reset timer is a first duration, and the first duration is a sum of durations of all reset timers started for restoring the SIM card to a normal state when the SIM card is dropped last time.
For example, when the terminal device drops the SIM card last time, after N2 times of the first cold reset operation, the state of the SIM card is still the card dropping state. The terminal equipment starts a reset timer 1 to trigger the execution of a cold reset operation 1, the cold reset operation 1 is unsuccessful, and starts a reset timer 2 to trigger the execution of a cold reset operation 2. The time length of the reset timer 1 is 5 seconds, and the time length of the reset timer 2 is 6 seconds. Then, this time the SIM card is dropped, the duration of the first reset timer (i.e. the first reset timer) started by the terminal device is 11 seconds. Since the SIM card was restored to the normal state last time, the sum of the durations of the reset timers started is 11 seconds. When the SIM card is dropped, after N2 times of the first cold reset operation, it is likely that it will need to wait 11 seconds to recover the SIM card to the normal state through the cold reset operation. Therefore, in order to reduce the frequency of the terminal device performing cold reset operation on the SIM card and reduce the power consumption of the terminal device, the terminal device may determine the duration of the first reset timer started when the SIM card is dropped by referring to the sum of the durations of the last SIM card drop and the reset timer started by the terminal device.
In one possible implementation, if the first duration is less than the first duration threshold, the duration of the first reset timer is the first duration; if the first duration is greater than the first duration threshold, the duration of the first reset timer is a preset duration, and the preset duration is less than the first duration threshold. The preset duration may be preset by the system.
For example, if the first duration is 50 seconds, the first duration threshold is 20 seconds, and the preset duration is 10 seconds. Then, the duration of the first reset timer is 10 seconds. This is because, if the first time length is too long, setting the first time length to the time length of the first reset timer may cause the user to wait long before the SIM card is restored to the normal state. Therefore, in order to reduce the time for the user to wait for the SIM card to return to the normal state, the duration of the first reset timer may be set to a preset duration when the first duration is too long. After the duration of the first reset timer is set to the preset duration, it is also possible to restore the SIM card to a normal state through the second cold reset operation. Therefore, based on the possible implementation mode, the time for the user to wait for the SIM card to recover to the normal state is favorably reduced.
In another possible implementation, if the first duration is greater than the first duration threshold, the terminal device may output a selection item of the first duration and the preset duration, so that the user may select whether to set the first time as the duration of the first reset timer or to set the preset time as the duration of the first reset timer. And the terminal equipment sets the time length selected by the user as the time length of the first reset timer. This can better meet the needs of the user.
In one possible implementation, the control switches for N1 hot resets, N2 cold resets, and N3 cold resets can be stored in NV, so as to ensure that the original reset times are unchanged after the reset is successful, and the control switches are ready for the next use.
In a possible implementation, if the state of the SIM card is still in the card-off state after N2 times of the first cold reset operation, the terminal device may not output the first prompt message. But directly performs steps 204 to 205.
In a possible implementation, after the terminal device performs N2 times of the first cold reset operation, if the state of the SIM card is still in the card-off state, the terminal device may not perform step 204 and step 205. Subsequent users may manually restart the terminal device to recover the SIM card.
In another possible implementation, the terminal device may not perform step 206 and step 207. That is, after the first cold reset operation is performed on the SIM card N2 times, the state of the SIM card is still in the card-off state, and the terminal device subsequently performs only one cold reset operation on the SIM card.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a SIM card recovery apparatus according to an embodiment of the present invention, where the SIM card recovery apparatus may be a terminal device or an apparatus (e.g., a chip) having a function of the terminal device.

In a possible implementation, the prompting unit is further configured to, when the number of cold reset operations performed on the SIM card after N2 times of the first cold reset operation reaches N3 times, stop performing the cold reset operation on the SIM card if the state of the SIM card is still in the card drop state, and output second prompting information, where the second prompting information is used to prompt the user to insert the SIM card again, and N3 is greater than 1.
In one possible implementation, the duration of the first reset timer is a first duration, and the first duration is a sum of durations of all reset timers started for restoring the SIM card to a normal state when the SIM card is dropped last time.
In one possible implementation, if the first duration is less than the first duration threshold, the duration of the first reset timer is the first duration; if the first duration is greater than the first duration threshold, the duration of the first reset timer is a preset duration, and the preset duration is less than the first duration threshold.
