Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The method for re-identifying the SIM card after the SIM card is removed can be applied to terminal equipment, and the terminal equipment can be but is not limited to various personal computers, notebook computers, smart phones, tablet computers and portable wearable equipment, and can also be some outdoor communication equipment, for example: relay stations, vehicle-mounted communication devices, industrial communication devices, and the like.
In an embodiment, as shown in fig. 1, a method for re-identifying a card after a SIM is removed is provided, which is described by taking the method applied to the terminal as an example, and includes the following steps:
In the process of using the communication module to communicate with the base station, the communication module can normally communicate with the base station after the SIM card is used for registering on the network. Optionally, the SIM card and the communication module may be in a form that the SIM card is connected with the communication module as a peripheral of the communication module, or the SIM card may be integrated inside the communication module. However, in any existing form, the SIM card is usually affected by strong factors in some special environments, such as: the SIM card in the communication module is in an out-of-place state due to low temperature, pressure, instant vibration and the like, and the communication module is disconnected from the network communication of the base station due to the fact that the SIM card is out of place.
In this case, the communication module generally sets a Reread (Reread) mechanism, that is, the communication module may continuously initiate several times of Reread card operations, and optionally, the Reread card operations may be performed by detecting a connection condition between an in-place detection pin of the SIM card and a pin of the communication module, or by detecting a level change condition of the in-place detection pin, to determine whether the SIM card is in place. But after the in-place detection is carried out for a plurality of times continuously, if the communication module can not detect that the SIM card is in an in-place state; at this time, the communication module gives up reading the card again, and no longer supplies power to the SIM card, and no longer communicates with the SIM card, resulting in disconnection of communication between the communication module and the base station. After that, if the communication module wants to recover the communication, the normal communication can be recovered only by manually plugging and unplugging the communication module in the field or inputting an initialization command. This results in high manual maintenance costs and inefficient recovery of the SIM card.
After the SIM card is dropped, carrying out on-site detection on the SIM card for continuous preset times according to the existing SIM card recovery method; if the SIM card is not detected to be in place after the in-place detection is performed for the preset number of times, the CPU of the communication module is controlled to perform a delay operation, where the delay operation includes waiting for a preset duration (that is, the terminal controls the CPU to wait for the preset duration). Optionally, the preset waiting time may be several seconds, several minutes, or several hours; the time delay operation can provide a recovery time for waiting for a preset time for the SIM card, and the SIM card is not directly abandoned for reading. For example: when the communication module is in a low-temperature state, such as-30 ℃, the SIM card may drop, if a re-reading mechanism in the existing communication module is adopted, after the SIM card is re-read for a plurality of times continuously, the terminal detects whether the SIM card is in place for the plurality of times continuously, and if the SIM card is not detected yet, the card reading is abandoned again; however, after the temperature rises, the SIM card returns to the on-site state again, but at this time, the communication module has abandoned the operation of reading the card again, so that the communication module cannot return to the networking state. However, after the delay operation is set, if the temperature rises back and the SIM card is in an in-place state within the recovery time of waiting for the preset duration, the communication module may detect the in-place state of the SIM card again after the preset duration is over.
And 102, after the preset duration is over, controlling the CPU to electrify the SIM card, and executing the in-place checking operation of the SIM card again to obtain a detection result.
After the SIM card is disconnected, the communication module powers up the SIM card again, that is, the communication module powers up the SIM card again, and the SIM card can perform a series of subsequent operations only when powered, and optionally, the SIM card can be connected to the communication module only when powered.
Specifically, after the CPU controlling the communication module executes the delay operation and the waiting preset time period is over, the communication module controls the CPU to power on the SIM card and execute the in-place check operation of the SIM card again on the SIM card. Optionally, the connection state between the in-place detection pin of the SIM card and the pin of the communication module may be determined according to the level change condition of the in-place detection pin of the SIM card by detecting the level change condition of the in-place detection pin of the SIM card, so that whether the SIM card is in place or not may be known. Generally, before the SIM card is connected to the communication device, the presence detection pin of the SIM card is in an initial level state, and accordingly, the initial level state corresponds to the SIM card being in a non-presence state. When the level of the in-place detection pin of the SIM card changes, the in-place detection pin of the SIM card and the pin of the communication module are in a connection state, and the SIM card is in an in-place state; if the level of the on-site detection pin of the SIM card is not changed, the on-site detection pin of the SIM card and the pin of the communication module are in an unconnected state, and the SIM card is in an off-site state.
Optionally, before the SIM card is connected to the communication device, an initial level of the in-place detection pin of the SIM card may be a high level, and when the level of the in-place detection pin of the SIM card changes to a low level, it indicates that the in-place detection pin of the SIM card is connected to the pin of the communication module, which indicates that the SIM card is in an in-place state, and an obtained detection result is that the SIM card is in the in-place state; when the level of the on-site detection pin of the SIM card is high, it indicates that the on-site detection pin of the SIM card is not connected to the pin of the communication module, which indicates that the SIM card is in an off-site state, and the obtained detection result indicates that the SIM card is in the off-site state.
And 103, determining whether to execute the time delay operation again according to the detection result.
And performing in-place checking operation of the SIM card again on the SIM card to obtain a detection result, wherein the detection result comprises that the SIM card is in an in-place state or the SIM card is in an out-of-place state.
Specifically, after the CPU performs a delay operation, the terminal controls the CPU to perform the in-place check operation of the SIM card on the SIM card again, and obtains the detection result, so that it can be known whether the SIM card is in place or not in place at this time according to the detection result. Optionally, if the detection result indicates that the SIM card is not in place, the CPU may be controlled to execute the second time delay operation again to provide a second chance of reading the card for the re-identification card of the communication module, that is, to provide a second chance of detecting whether the SIM card is in place for the communication module; and controlling the CPU to execute the second time delay operation, which is actually controlling the CPU to wait for a preset time period again (optionally, the preset time period of the second time waiting may be the same as or different from the preset time period of the first time waiting), and after the second time waiting is finished, the terminal controls the CPU to power on the SIM card again, and executes the in-place check operation of the SIM card again to obtain a check result, and in the case that the detection result of this time is that the SIM card is in the in-place state, the card information of the SIM card can be read.
Specifically, when the card information of the SIM card is read, the SIM card may be initialized and then the card information of the SIM card is read, network registration is performed through the read card information of the SIM card, and after the SIM card successfully registers the network, communication between the communication module and the base station may be realized, and normal operation may be resumed. During the normal operation of the SIM card, the communication module will periodically detect whether the SIM card is dropped, and determine whether to execute the above-described delay operation or other procedures according to the detection result.
In summary, in this embodiment, after the SIM card is dropped, the communication module may continuously detect the presence of the SIM card for multiple times; if the SIM card is not in place after being checked for many times, controlling a CPU to execute a delay operation with preset time length, electrifying the SIM card again after the delay operation with the preset time length is finished, and detecting the in-place condition of the SIM card to obtain a detection result; if the detection result is that the SIM card is in an out-of-place state after the time delay operation is executed for the first time, controlling the CPU to execute the time delay operation with a preset time length again, wherein the preset time length can be longer than the preset time length when the time delay operation is executed for the first time; after the delay operation with the second preset time length is finished, controlling the CPU to electrify the SIM card, and executing the in-place inspection operation of the SIM card again to obtain a detection result; if the in-place detection result is that the SIM card is not in the in-place state, the third time of delay operation can be executed, and after the third time of delay operation is finished, the in-place checking operation of the SIM card is executed again; in this way, if the SIM card is not detected after the preset number of delay operations is performed, optionally, the communication module may be restarted, and before the communication module is restarted, it is ensured that the user data of the communication module before the restart operation and the running state data of the communication module are stored, so as to ensure that the communication module after the restart can be restored to the previous running state without losing the historical user data.
According to the method, the device, the computer equipment and the storage medium for re-identifying the SIM card after the SIM card is removed, after the SIM card is detected to be out of position for a continuous preset number of times, the CPU of the communication module is controlled to execute the delay operation, wherein the delay operation comprises the following steps: waiting for a preset time length; after the preset time length is finished, controlling the CPU to electrify the SIM card, and executing the in-place checking operation of the SIM card again to obtain a detection result; and determining whether to execute the delay operation again according to the detection result. That is, after the SIM card is dropped, after the SIM card is subjected to continuous multiple in-place detections, or the SIM card is not detected, the CPU of the communication module in which the SIM card is located is controlled to perform a delay operation (i.e., the CPU is controlled to wait for a preset time), and after the CPU waits for the preset time, the CPU is controlled to power on the SIM card again, and the in-place detection of the SIM card is performed, so as to obtain a detection result; and determines whether to perform the delay operation again according to the detection result, instead of giving up reading the card again. Therefore, the time delay operation can be used for avoiding the abandoning and card reading operation of the communication module on the SIM card after the communication module detects that the SIM card is not in place for the continuous preset times, in addition, the self-recovery card reading efficiency of the communication module can be improved through the time delay module, the self-recovery card reading opportunity of the communication module is increased, the manual recovery of the communication module from the field is avoided, the cost of manual operation is reduced, and the recovery efficiency of the SIM card is improved.
Fig. 2 is a schematic flow chart of a method for re-identifying a SIM card after the SIM card is removed in another embodiment, which relates to an optional implementation process of a change condition of a register status bit in a SIM card re-identifying process. On the basis of the above-described embodiment, as shown in fig. 2.
In the communication module, the in-place situation of the SIM card can be represented by setting a register status bit, and the CPU is instructed to execute relevant operations according to the change situation of the register status bit; optionally, the register status bit may be used to instruct the CPU to perform a delay operation, or may be used to instruct the CPU to perform a power-on operation on the SIM card.
Specifically, after detecting the presence of the SIM card, the communication module selects a register status bit capable of marking the status of the SIM card and having an interrupt trigger function, and sets the register status bit to a first level, where optionally, the first level may indicate that the SIM card is currently in a present status; when the SIM card is dropped and no SIM card is detected for a preset number of times, the communication module may control the preset register status bit to change from a first level to a second level, where the first level and the second level are two levels with opposite logics; optionally, the second level may be used to indicate that the SIM card is in an out-of-place state, and in addition, the second level may be used to instruct the CPU to perform a delay operation. For example: under the condition that the SIM card is in normal operation, the SIM card can be represented to be in an in-place state by setting the status bit of the register to be 1; when the SIM card is in a card-off state, the SIM card can be represented in an off-bit state by controlling the register status bit to be changed from 1 to 0, namely when the register status bit is 0; alternatively, the CPU may be instructed to perform a latency operation when the register status bit is 0.
Specifically, after the SIM card detects that the SIM card is not in place for a preset number of times, the SIM card controls the preset register state bit to be changed from the first level to the second level, so as to instruct a central processing unit CPU of a communication module where the SIM card is located to execute a delay operation of a preset duration; and when the CPU executes the delay operation with the preset time length and the delay of the preset time length is finished, the communication module controls the preset register state bit to be changed from the second level to the first level again so as to indicate the CPU to electrify the SIM card. For example: based on the example in step 201, after the delay operation is ended, the register status bit may be changed from 0 to 1 again, and when the register status bit is 1, the CPU may be instructed to execute a power-on operation on the SIM card.
In step 203, if the detection result is that the SIM card is not in the on-bit state, the register state bit is controlled to change from the first level to the second level again, so as to instruct the CPU to perform the delay operation again.
After the CPU powers on the SIM card according to the change of the register status bit, the in-place check operation of the SIM card is executed again, that is, whether the SIM card is in place or not is determined by checking the connection state between the in-place detection pin of the SIM card and the pin of the communication module, so as to obtain the detection result. If the detection result is that the SIM card is in the not-in-place state, the terminal controls the register state bit to change from the first level to the second level again so as to instruct the CPU to execute the delay operation again.
Optionally, the preset time lengths corresponding to each time of executing the delay operation are different, and the size of the preset time length corresponding to the current time of executing the delay operation is larger than the size of the preset time length corresponding to the previous time of executing the delay operation. For example: when the terminal controls the CPU to execute the first time delay operation, the first preset time length is set to be 30 seconds; the terminal may set the preset time length for the second time to be 90 seconds when controlling the CPU to execute the delay operation for the second time, that is, the preset time length corresponding to the delay operation for the second time may be longer than the preset time length corresponding to the delay operation for the first time.
In this embodiment, the communication module changes the register state bit from a first level to a second level to instruct the CPU to perform a delay operation of a preset duration by setting a register state bit capable of marking a bit state of the SIM card and having an interrupt trigger function, and detecting that the SIM card is not in place; after the delay operation of the preset time length is finished, controlling the state bit of the register to be changed from the second level to the first level again so as to indicate the CPU to electrify the SIM card, and executing the on-site checking operation of the SIM card again to obtain a detection result; if the detection result is that the SIM card is in the out-of-position state, the state bit of the register is controlled to be changed from the first level to the second level again so as to instruct the CPU to execute the delay operation with a preset time length again. The execution operation of the CPU is controlled by the continuous change of the status bit of the register, so that the control logic of the terminal to the CPU is simplified; in addition, the embodiment can also avoid abandoning the card re-reading operation of the SIM card after the communication module detects that the SIM card is not in place for the continuous preset times, can avoid abandoning the card re-reading operation of the SIM card after the communication module detects that the SIM card is not in place for the continuous preset times by setting the state bit of the register and the time delay operation, in addition, the autonomous recovery card reading efficiency of the communication module can be improved through the time delay module, the autonomous recovery card reading chance of the communication module is increased, the manual recovery of the communication module from the field is avoided, the cost of manual operation is reduced, and the recovery efficiency of the SIM card is improved.

In step 304, the preset register status bit is controlled to change from the first level to the second level to instruct the CPU to perform the delay operation.
And 305, after the preset time delay is finished, controlling the preset register state bit to be changed from the second level to the first level again to indicate the CPU to power on the SIM card, and executing the on-site checking operation of the SIM card again to obtain the detection result.
