Description

Technical Field

[0001] The present application relates to the field of communication technologies, and in particular, to a method, apparatus, electronic device, and readable medium for processing SIM card writing and erasing operations. Background Art

[0002] A SIM (subscriber identification module) is an identification card used to uniquely identify a mobile user in a cellular mobile communication system. The SIM card stores user data, authentication methods, and keys, which can be used by the communication network to authenticate the user's identity.

[0003] When the SIM card terminal is in some specific scenarios, it is necessary to frequently perform SIM card file writing and erasing operations. For example, the terminal device is at the edge of two cells, traveling at high speed, in arrears, or frequently powered on and off. Even in these scenarios, some data does not need to be actually written to the SIM card immediately because it will soon be overwritten by new data. However, once the terminal device is in such a scenario, it will perform frequent and unnecessary writing and erasing operations on the SIM card. Frequent and unnecessary SIM card writing and erasing will shorten the service life of the SIM card, increase the maintenance cost of the device, and the risk of potential service interruption.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0025] In subsequent descriptions, suffixes such as "module", "component", or "unit" used to represent elements are only for the convenience of description of the present application, and they have no specific meaning in themselves. Therefore, "module" and "component" can be used interchangeably.

[0026] A SIM (subscriber identification module) is an identification card used to uniquely identify a mobile user in a cellular mobile communication system. The SIM card stores user data, authentication methods, and keys, which can be used by the communication network to authenticate the user's identity.

[0027] When the SIM card terminal is in some specific scenarios, it is necessary to frequently perform SIM card file erasing and writing operations. For example, the terminal device is at the edge of two cells, traveling at high speed, in arrears, or frequently powered on and off, etc. Even in these scenarios, some data does not need to be actually written to the SIM card immediately because it will soon be overwritten by new data. However, once the terminal device is in such a scenario, it will perform frequent and unnecessary erasing and writing operations on the SIM card. Frequent and unnecessary SIM card erasing and writing will shorten the service life of the SIM card, increase the maintenance cost of the device, and the risk of potential service interruption.

[0028] To solve the problems mentioned in the background art, according to one aspect of the embodiments of the present application, a method for processing SIM card erasing and writing operations is provided, as Figure 1 shown, including:

[0029] Step 101, detecting whether the SIM card terminal is currently in a preset scenario, where the preset scenario is a scenario that requires frequent erasing and writing of the SIM card;

[0030] Step 103, if it is determined that the SIM card terminal is currently in the preset scenario, start the SIM card protection mode and turn on the timer;

[0031] Step 105, when the timing duration of the timer is less than the preset duration, store the first data to be erased and written in the local cache;

[0032] Step 107, when the timing duration of the timer is equal to the preset duration, perform the target erasing and writing operation on the SIM card using the first data to be erased and written in the local cache.

[0033] The present application provides an embodiment for protecting the SIM card from being damaged by frequent erasing and writing in a preset scenario, while ensuring the timely update and accuracy of the data.

[0034] The preset scenario is a scenario that requires frequent erasing and writing of the SIM card. The preset scenario can have multiple scenarios (such as, the terminal device is at the edge of two cells, traveling at high speed, the SIM card is in arrears, or frequently powered on and off, etc.), including but not limited to the scenarios listed in the present application.

[0035] The preset duration can be set according to the actual situation, and the present application does not limit this.

[0036] The present application adds a judgment mechanism for the scenario where the SIM card terminal is located. If the SIM card terminal is in a frequent erasing and writing scenario, the protection mode is turned on. In the protection mode, the data to be erased and written is first stored in the local cache, and then the erasing and writing operations are uniformly performed every certain duration, which can effectively reduce the number of erasing and writing times.

[0037] As an alternative embodiment, detecting whether the SIM card terminal is currently in a preset scenario includes: detecting whether the number of handovers of the area where the SIM card terminal is located within a first duration is greater than a first number; if the number of handovers is greater than the first number, it is determined that the SIM card terminal is currently in the preset scenario; or detecting whether the number of consecutive power - on / off operations of the SIM card terminal within a second duration is greater than a second number; if the number of consecutive power - on / off operations is greater than the second number, it is determined that the SIM card terminal is currently in the preset scenario.

[0038] Specifically, the first duration, the second duration, the first number, and the second number can be set according to the actual situation, and the present application does not limit the specific values.

[0039] Exemplarily, if it is detected that the number of consecutive cell handovers of the SIM card terminal within a time interval T is greater than n, it is determined that the terminal enters the high - speed driving state. At this time, the SIM card protection mode is enabled, and the write - protection of the corresponding file is enabled, where T and n need to be determined according to the specific scenario of the terminal. For example, if it is an automobile or an electric vehicle, then T can be set to 2 minutes and n can be set to 3 times; if it is a bicycle, then T can be set to 3 minutes and n can be set to 2 times.

[0040] Exemplarily, if it is detected that the registration of the SIM of the terminal in the HPLMN, EHPLMN, and RPLMN is continuously rejected and the reason for rejection is "No suitable cells in tracking area", it is determined that the SIM card is in an overdue scenario. At this time, the SIM card protection mode is enabled, and the write - protection of the corresponding file is enabled. When the registration is successful, the SIM card protection mode is exited.

[0041] Exemplarily, if it is detected that the SIM card terminal has more than 3 cell handovers in two cells within 1 minute and the signal change is greater than 6 dBm, it is determined that the SIM card terminal is at the cell edge. At this time, the SIM card protection mode is enabled, and the write - protection of the corresponding file is enabled.

[0042] Exemplarily, if it is detected that the number of consecutive power - on / off operations of the SIM card terminal within a unit time T exceeds N times, it is determined that the SIM card terminal is in a scenario of repeated power - on / off operations. At this time, the SIM card protection mode is enabled, and the write - protection of the corresponding file is enabled.

[0043] It should be noted that since different files store different data, the files to be protected are different in different scenarios. For example, when the SIM card terminal is moving at high speed or at the edge of the cell, the file to be protected is the EFepsloci file; when the SIM card terminal is in arrears, the files to be protected are the EFFPLMN and EFepsloci files; when the SIM card terminal is in a frequent power-on and power-off state, the files to be protected are the EFepsloci and EFepsnsc files.

[0044] In the embodiments provided by the present application, in addition to scenario judgment, the SIM card terminal can also be forced to enter and exit a certain scenario by sending an instruction.

[0045] By adding a mechanism for judging the scenario in which the SIM card terminal is located, the present application can enable the protection mode in a scenario of frequent erasing and writing to avoid increasing unnecessary erasing and writing times.

[0046] As an optional embodiment, storing the first data to be erased and written in the local cache includes: obtaining the first data to be erased and written; setting a temporary flag bit in the local cache and performing a storage operation on the first data to be erased and written; when it is determined that the first data to be erased and written has been stored in the local cache, updating the temporary flag bit to the target flag bit.

[0047] When receiving an erasing and writing instruction, obtain the first data to be erased and written from the erasing and writing instruction. The first data to be erased and written depends on the application scenario and requirements of the SIM card, and the present application does not limit its specific content.

[0048] Before data storage, first set a temporary flag bit in the local cache to identify that there is currently data waiting to be stored but the storage process has not been completed.

[0049] Store the first data to be erased and written in the local cache. After the data storage is completed, perform necessary verification steps to confirm that the data has been correctly stored in the local cache, and then update the temporary flag bit to the target flag bit.

[0050] By first storing the first data to be erased and written in the local cache and then uniformly writing it into the SIM card, frequent erasing and writing of the SIM card can be avoided. Moreover, setting the flag bit can clearly identify the storage status of the data in the local cache, such as "being stored", "storage completed", etc., which helps the system or application program to track the storage progress of the data in real time and ensure the correctness and integrity of the data.

[0051] As an alternative embodiment, performing a target erasing operation on the SIM card by using the first data to be erased cached locally includes: checking whether a target flag bit exists in the local cache; if the target flag bit exists in the local cache, reading the first data to be erased in the local cache; determining whether there is data in the SIM card that duplicates the data to be written in the first data to be erased; if there is no data in the SIM card that duplicates the data to be written, writing the data to be written into the SIM card.

[0052] After the timing duration of the timer reaches the preset duration, performing the target erasing operation includes: comparing the new file in the local cache (i.e., the first data to be erased) with the file in the SIM card, that is, determining whether there is data in the SIM card that duplicates the data to be written in the first data to be erased); if they are different, writing the new data in the cache into the SIM card and updating the file on the SIM card.

[0053] During the target erasing operation, it is necessary to check whether a target flag bit exists in the local cache. If the target flag bit exists, it means there is new data in the local cache that can be written into the SIM card. If the target flag bit does not exist, it means there is no new data in the local cache that can be written into the SIM card.

[0054] In addition, in addition to setting the flag bit as a temporary flag bit or a target flag bit to indicate whether the data is stored or not, the status of the flag bit can also be set to true to indicate that the data is successfully stored in the local cache, and the status of the flag bit can be set to false to indicate that the data has not been stored in the local cache temporarily.

[0055] After writing the data to be written into the SIM card, erase the target flag bit so that the flag bit can be reset when new data is stored in the local cache next time.

[0056] In the embodiment provided in the present application, the data writing operation in the cache can also be triggered by sending an instruction or calling an interface, and the data in the cache is directly written into the SIM card, which is mainly used when the customer needs to restart the machine or change the card, and the data can be written into the SIM card in time.

[0057] As an alternative embodiment, after performing the target erasing operation on the SIM card by using the first data to be erased cached locally, the method further includes: clearing the timer and controlling the timer to start timing again; when the new timing duration of the timer is less than the preset duration, storing the second data to be erased in the local cache; when the new timing duration of the timer is equal to the preset duration, performing the target erasing operation on the SIM card by using the second data to be erased cached locally.

[0058] In the embodiments provided in the present application, data in the local cache is written into the SIM card every preset time interval. After the data writing is completed, the timer needs to restart timing. In the case where the SIM card is in the protection mode, the following steps are cycled: when the new timing duration of the timer is less than the preset time interval, the second data to be erased is stored in the local cache; when the new timing duration of the timer is equal to the preset time interval, the target erasing operation is performed on the SIM card using the second data to be erased in the local cache.

[0059] Data in the local cache is written into the SIM card every preset time interval. In this process, it involves two parts: storing new data in the local cache and writing the new data in the local cache into the SIM card. The specific steps of these two parts have been described above and will not be elaborated here.

[0060] As an alternative embodiment, after starting the SIM card protection mode and turning on the timer, the method further includes: monitoring whether the SIM card terminal is in a preset scenario; if it is monitored that the SIM card terminal is not in the preset scenario, the SIM card protection mode is turned off; obtaining the current timing duration of the timer and turning off the timer; obtaining the third data to be erased stored in the local cache during the current timing duration; performing the target erasing operation on the SIM card using the third data to be erased.

[0061] The present application repeats the step of writing data in the local cache into the SIM card every preset time interval according to the timing duration of the timer until it is monitored that the SIM card terminal exits the preset scenario, and then the SIM card protection mode is turned off. At this time, the necessary erasing operation to be performed is executed immediately.

[0062] When the SIM card protection mode is turned off, the current timing duration of the timer is usually less than the preset time interval. However, during the current timing duration, there may also be a situation where new data is stored in the local cache. Therefore, it is still necessary to obtain the third data to be erased stored in the local cache during the current timing duration, and then synchronize the third data to be erased to the SIM card according to the steps of the target erasing operation.

[0063] Turning off the SIM card protection mode when the SIM card terminal is not in the preset scenario can ensure that the necessary erasing operation is executed in a timely manner.

[0064] Synchronizing the third data to be erased in the local cache to the SIM card can ensure that the data in the SIM card is the latest data.

[0065] As an alternative embodiment, the method further includes: when a data reading instruction is received, determining a target file to be read corresponding to the data reading instruction; if the SIM card terminal is not in the SIM card protection mode, reading the target file from the SIM card, and if the SIM card terminal is in the SIM card protection mode, determining whether the target file belongs to a file to be protected; if the target file belongs to a file to be protected, reading the target file from the local cache and the SIM card, and if the target file does not belong to a file to be protected, reading the target file from the SIM card.

[0066] If the SIM card terminal is in the SIM card protection mode, it means that some files in the SIM card are in the protection mode, and the latest data of these files may still be cached locally. Therefore, at this time, these files need to be read from both the local cache and the SIM card.

[0067] There are already relatively mature technologies for reading file data from the SIM card, and this application will not elaborate on them here.

[0068] When reading data from the local cache, it is necessary to first check whether the target flag bit exists in the local cache. If the target flag bit exists, it means that there is new data to be written to the target file, and at this time, the new data in the local cache can be read. If the target flag bit does not exist, it means that there is no new data to be written to the target file, so there is no need to read the new data in the local cache at this time.

[0069] Figure 2 The following is a flowchart for reading and writing data files provided by this application. As shown in the figure, when it is necessary to read a SIM card file, since it is not certain whether the file has been written to the SIM card at this time, it is necessary to first determine whether the SIM card terminal is in the SIM card protection mode. If the SIM card terminal is not in the SIM card protection mode, it means that the file data in the SIM card is the latest data, and the SIM card file can be directly read from the SIM card. If the SIM card terminal is in the SIM card protection mode, it is necessary to further determine whether the SIM card file is in the protection mode (it can be determined which file is currently protected according to the current scenario of the SIM card). If the SIM card file is in the protection mode, the SIM card file is directly read from the local cache and the SIM card. If the SIM card file is not in the protection mode, the SIM card file is directly read from the SIM card to ensure that the data read is the latest data.

[0070] By determining whether the file is in the protection mode before reading the file and then selecting the reading location, rather than directly reading data from the SIM card, it is possible to prevent data omission caused by data not being written to the SIM card and ensure that the data read is the latest data.

[0071] Scenes that may frequently write to the card are identified through scene judgment. Files that will be frequently erased and written in these scenes are protected. During the protection process, the SIM card information that needs to be updated is written into the local cache instead of the SIM card. After leaving these scenes, the data in the local cache will be written into the SIM card, so as to achieve the purpose of reducing the number of erase and write operations.

[0072] This application provides a method for processing SIM card erase and write operations, including: detecting whether the SIM card terminal is currently in a preset scene, where the preset scene is a scene that requires frequent erase and write operations on the SIM card; if it is determined that the SIM card terminal is currently in the preset scene, start the SIM card protection mode and start a timer; when the timing duration of the timer is less than the preset duration, store the first data to be erased and written in the local cache; when the timing duration of the timer is equal to the preset duration, perform a target erase and write operation on the SIM card using the first data to be erased and written in the local cache. By adding a judgment mechanism to the scene where the SIM card terminal is located, if the SIM card terminal is in a frequent erase and write scene, the protection mode is enabled. In the protection mode, the data to be erased and written is first stored in the local cache, and then the erase and write operation is performed uniformly at regular intervals, which can effectively reduce the number of erase and write operations and solve the problem that frequent and unnecessary SIM card erase and write operations will shorten the service life of the SIM card.
