Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for updating Subscriber Identity Module (SIM) card system data.

Background

With the development of communication technology, programmable SIM cards such as embedded subscriber identity module (eSIM) cards are widely used in consumer terminals, in particular, terminals such as wearable devices, mobile phones, tablets, and personal computers. The programmable SIM card can run a separate operating system, namely a Card Operating System (COS), and like other Operating Systems (OS), the COS has a problem of requiring updating. Therefore, a method for updating the system data of the SIM card is needed.

In the prior art, when an eSIM card needs to be upgraded, a technician of a COS manufacturer generates a new version of COS, then the new version of COS and a related upgrade script are provided to a terminal manufacturer, and then the related technician of the terminal manufacturer runs the upgrade script in a research and development environment to manually update the COS in the eSIM card.

However, since it is necessary for a technician associated with a terminal manufacturer to obtain the new version of the COS and the upgrade script and manually update the COS in the eSIM card, efficiency and flexibility are low, and the off-line operation and maintenance cost is also increased.

Disclosure of Invention

In view of this, the present application provides a method and an apparatus for updating system data of an SIM card, so as to improve efficiency and flexibility of updating the system data and reduce offline operation and maintenance cost.

In order to achieve the above object, in a first aspect, an embodiment of the present application provides a method for updating SIM card system data, where the method includes:

verifying the updating description information based on the system information of the target SIM card;

and updating the system data in the target SIM card based on the target update file.

The update indication message may be used to indicate that the system data in the target SIM card may be currently updated (i.e. to indicate an opportunity to update the system data); and the update file can be used for updating the system data in the target SIM card.

It should be noted that the terminal may include at least one programmable SIM card, and the target SIM card may be one of the at least one programmable SIM card.

In the embodiment of the present application, when the update indication message of the target SIM card is detected, at least one piece of update description information may be acquired. Since the update description information may describe an update characteristic of an update file corresponding to the update description information, the update description information may be verified based on system information of the target SIM card. When a certain update description information passes the verification, the update description information is the target update description information, so that a target update file corresponding to the target update description information can be obtained, and the system data in the target SIM card is updated based on the target update file. That is, whether the system data needs to be updated or not can be automatically judged according to the acquired update description information, and when the system data needs to be updated, the corresponding target update file is acquired to update the system data, so that the COS does not need to be updated by the related technical personnel through the operation upgrade script under the research and development environment, the efficiency and the flexibility of updating the system data are improved, and the operation and maintenance cost is also reduced.

Optionally, the SIM card may include system data and user data, and the system data may include the COS, and the user data may include a profile (profile).

Alternatively, the update description information may be used to describe an update characteristic of an update file corresponding to the update description information. The update description information may include a first system vendor identification and at least one first system version identification, and may further include at least one of a third system version identification, an update file path, a system data erasure identification, and a user data erasure identification.

When the terminal acquires the update description information, the terminal may acquire the update description information according to the update description information address. The update description information address may be obtained by receiving user submission or setting in advance, and the update description information address may include a second network address pointing to a second preset server or a second local address pointing to the terminal home terminal. And when the update description information address includes the second network address, the update description information may be acquired through Over The Air (OTA) mode.

Optionally, the update indication message includes an update trigger instruction of the target SIM card or a power-on message of the target SIM card.

Optionally, the updating description information includes a first system vendor identifier and at least one first system version identifier, the system information includes a second system vendor identifier and a second system version identifier of system data in the target SIM card, and the checking the updating description information based on the system information of the target SIM card includes:

Optionally, the update description information further includes a third system version identifier.

Optionally, the checking the update description information based on the system information of the target SIM card includes:

Since the first system manufacturer identifier is the identifier of the system manufacturer corresponding to the update file, and the first system version identifier is the version identifier of the system data that can be updated based on the update file, when the first system manufacturer identifier is the same as the identifier of the second system manufacturer, it may be stated that the manufacturer corresponding to the update file is consistent with the manufacturer of the system in the target SIM card, and when the at least one first system version identifier includes the second system version identifier (i.e., the second system version identifier is one of the at least one first system version identifier), it may be stated that the current system version in the target SIM card is the same as the system version to which the update file is directed. Therefore, when the first system manufacturer identifier is the same as the second system manufacturer identifier and at least one first system version identifier includes the second system version identifier, it may be determined that the verification is passed, and subsequent steps may be continuously performed to update the system data in the target SIM card, otherwise, it may be determined that the verification is not passed, and thus the system data is not updated. That is, on one hand, the terminal can compare the first system manufacturer identifier with the second system manufacturer identifier of the target SIM card, so as to ensure that the system data of the target SIM card is updated through the update file corresponding to the manufacturer of the system in the target SIM card, thereby being capable of updating the system data of different manufacturers; on the other hand, the at least one first system version identification is compared with the second system version identification in the target SIM card, so that the system data of the target SIM card is ensured to be updated through the update file which is adaptive to the system data in the target SIM card, and whether the programmable SIM cards with the system data of different versions are updated based on the update file can be flexibly and accurately controlled.

Optionally, the checking the update description information based on the system information of the target SIM card includes:

when the first system vendor identifier in the update description information is the same as the second system vendor identifier, any one of the first system version identifiers in the update description information is the same as the second system version identifier, and the third system version identifier in the update description information is higher than the third system version identifier and the second system version identifier included in other update description information in the at least one update description information, it is determined that the update description information passes verification.

Optionally, the checking the update description information based on the system information of the target SIM card includes:

when the first system vendor identifier in the update description information is the same as the second system vendor identifier, any one of the first system version identifiers in the update description information is the same as the second system version identifier, the third system version identifier in the update description information is higher than the third system version identifier included in other update description information in the at least one update description information, and the third system version identifier in the update description information is lower than the second system version identifier, it is determined that the update description information passes verification.

If the third system version identifier is higher than the second system version identifier, the update may be a system rollback, and if the third system version identifier is lower than the second system version identifier, the update may be to a higher version, so that the third system version identifier may be compared with the second system version identifier, and system rollback may be selected or prevented according to different requirements, thereby further improving flexibility of updating system data.

Alternatively, the first system version identification may comprise a plurality of levels of sub-first system version identifications, and the second system version identification may comprise a plurality of levels of sub-second system version identifications.

Optionally, the obtaining of the target update file corresponding to the target update description information includes:

and when the target update description information comprises an update file path, acquiring the target update file based on the update file path.

Optionally, the updating file path includes a first network address, and the obtaining the target updating file based on the updating file path includes:

and acquiring the target update file from a first preset server based on the first network address.

Optionally, the target update file is stored in a first preset server, and the update description information is stored in a second preset server, where the first preset server includes a server of a system manufacturer in the target SIM card, a server of a terminal manufacturer, or a server different from the server of the system manufacturer and the server of the terminal manufacturer; the second preset server includes a server of the system manufacturer, a server of the terminal manufacturer, or a server different from the server of the system manufacturer and the server of the terminal manufacturer.

Optionally, the first preset server and the second preset server are the same server.

It should be noted that the first preset server and the second preset server may be different server modules in the same server or different servers in the same server cluster. When the first preset server is the same as the second preset server, the first preset server and the second preset server may be the same server module in the same server or the same server in the same server cluster.

It can be seen that, in the embodiment of the present application, sources of the update description information and the update file are not limited, the terminal may flexibly obtain the update description information according to the update description information address, and obtain the target update file according to the update file path, instead of obtaining the update file and the update description information only from a system manufacturer of the target SIM card (or called a system data manufacturer), which may implement decoupling between system data in the SIM card and a system data manufacturer, and further improve flexibility of updating the system.

It should be further noted that the file in which the update description information is located may be the same file as the corresponding update file.

Optionally, the obtaining of the target update file corresponding to the target update description information includes:

acquiring an update file set, wherein the update file set comprises at least one update file;

and acquiring the target update file corresponding to the target update description information from the update file set.

Optionally, the target update file includes an Application Protocol Data Unit (APDU) write instruction set, and updating the system data in the target SIM card based on the target update file includes:

and sending the APDU writing instruction set to the target SIM card.

Optionally, the target update file further includes a version identifier update instruction set and a power-on instruction set, and after the sending the APDU write instruction set to the target SIM card, the method further includes:

and sequentially executing the version identification updating instruction set and the power-on instruction set.

And updating the second system version identifier in the target SIM card into a third system version identifier carried by the updating description information through the version identifier updating instruction. Of course, if the target update description information does not carry the third system version identifier, the target update description information may also be updated according to the preset version identifier generation rule and the second system version identifier to generate the third system version identifier, and the second system version identifier is replaced with the third system version identifier.

Optionally, when the target update description information includes a user data erasure identifier, the target update file further includes a user data erasure instruction set, and before the sending the APDU write instruction set to the target SIM card, the method further includes:

executing the user data erasure instruction set.

Optionally, before the updating the system data in the target SIM card based on the target update file, the method further includes:

and outputting user data erasure prompt information.

Optionally, when the target update description information includes a system data erasure flag, the target update file further includes a system data erasure instruction set, and before the sending the APDU write instruction set to the target SIM card, the method further includes:

executing the system data erasure instruction set.

Wherein the system data erasure flag may be represented by a character string. If the update description information includes a system data erasure identifier, it can be shown that the update is to completely update the system data (i.e., upgrade), and the system data needs to be erased; if the update description information does not include the system data erasure identifier, it can be shown that the update is to update the system data in a patching manner (i.e., update), and the system data does not need to be erased.

For example, the system data erasure indicator may be replaced by a full update indicator and a patch update indicator. When the update description information includes the complete update indication identifier, it may be indicated that the update is to completely update the system data, and when the update description information includes the patch update indication identifier, it may be indicated that the update is to update the system data in a patching manner.

Optionally, before the updating the system data in the target SIM card based on the target update file, the method further includes:

and outputting system data erasure prompt information.

Optionally, the target update file further includes an update mode setting instruction set, and before the sending the APDU write instruction set to the target SIM card, the method further includes:

executing the update mode setting instruction set.

Since the target update file includes the APDU write instruction set, the version identifier update instruction set, and the power-on reset instruction set, and may further include at least one of the system erase instruction set, the user data erase instruction set, and the update description information may include at least one of the system data erase identifier and the user data erase identifier, when updating the system data in the target SIM card, it may be determined whether the update is update or upgrade according to the target update description information, whether the system data or the user data needs to be erased first, and the corresponding manner of updating the system data may include the following several cases:

in a possible implementation manner, the target update description information does not include a system data erasure identifier or a user data erasure identifier, and therefore system data and user data do not need to be erased, the terminal may send the APDU write instruction set to the target SIM card, and after the target SIM card executes the APDU write instruction set, the terminal may sequentially execute the version identifier update instruction and the power-on instruction.

In another possible implementation manner, the target update description information does not include a system data erasure identifier, but includes a user data erasure identifier, and the system data may not be erased, then the terminal may execute the user data erasure instruction set first, and then send the APDU write instruction set to the target SIM card, and after the target SIM card has executed the APDU write instruction set, may execute the version identifier update instruction set and the power-up instruction set again.

In another possible implementation manner, the target update description information includes a system data erasure flag, but does not include a user data erasure flag, the system data may be erased, then the terminal may execute the system data erasure instruction set first, then send the APDU write instruction set to the target SIM card, and after the target SIM card executes the APDU write instruction set, may execute the version flag update instruction set and the power-up instruction set again.

In another possible implementation manner, the target update description information includes a system erasure flag and a user data erasure flag, and before sending the APDU write instruction set to the target SIM card, the system data and the user data need to be erased first, that is, the system data erasure instruction set, the user data erasure instruction set, and the update mode setting instruction set may be executed in any order, and then the APDU write instruction set may be sent to the target SIM card, and after the target SIM card executes the APDU write instruction set, the version flag update instruction set and the power-on instruction set may be executed.

It should be noted that, after sending the APDU write instruction set to the target SIM card, the terminal may not execute the version identifier update instruction set and the power-on instruction set.

It should be noted that, when the target update description information does not include the system data erasure flag, the update mode setting instruction set may be obtained from the target update file and executed before the APDU write instruction set is executed, regardless of whether the target update description information includes the user data erasure flag.

That is, by splitting the update file into a plurality of instruction sets and combining the update description information, the instruction sets can be dynamically increased, decreased and arranged according to the actual update requirements, the update (update) without erasing the system data and the update (update) with erasing the system data can be simultaneously satisfied, and the flexibility of updating the system data is further improved.

Optionally, the sending the APDU write instruction set to the target SIM card includes:

Detailed Description

In order to facilitate understanding of the technical solutions in the embodiments of the present application, an application scenario of the embodiments of the present application is first described below.

The SIM card is a subscriber identity card of a digital cellular mobile phone, which can be understood as a key for accessing a terminal device to a mobile network, and has functions of storing data, authenticating a subscriber identity under secure conditions, encrypting subscriber information, and the like. The SIM card may include system data and user data.

The system data may include the COS, the user data may include a Profile (Profile), and the user data may be used for authentication when the terminal joins the mobile network. Of course, in practical applications, the system data and the user data may also include other types of data, and this embodiment of the present application is not particularly limited to this system data and user data.

At present, common physical SIM cards are gradually replaced by programmable SIM cards due to their large size and the need for setting corresponding card slots in the terminal. The data in the programmable SIM card can be erased and rewritten, and may include an eSIM card, a vmsim card, or an iSIM card. An eSIM card, or an embedded universal integrated circuit card (eUICC) card, may be a chip embedded on a terminal board. The vmsim card, or a virtual integrated circuit (vUICC) card, may simulate the related functions of the SIM card through software, without the existence of a physical chip. The iSIM card, or an integrated universal integrated circuit card (uiicc), may integrate the SIM card into a processor of the terminal, that is, a physical chip is not separately configured to be used as the SIM card. Certainly, in practical applications, the programmable SIM card may also be implemented in other forms, and the implementation manner of the programmable SIM card is not specifically limited in this application embodiment.

The programmable SIM card needs to be connected to a server of the network operator, from which the user data is downloaded, installed and activated before being able to connect to the mobile network based on the user data. During the use of the programmable SIM card, the system data in the programmable SIM card may need to be updated, for example, to be compatible with the user data from different network operators, to be updated accordingly, or to be functionally updated.

In the prior art, the COS in the eSIM card can be updated, and the updating process is mainly implemented by a technician of a terminal manufacturer obtaining a new version of the COS and a related upgrade script from the COS manufacturer, then running the upgrade script in a research and development environment, and updating the new version of the COS into the eSIM card. However, this method is cumbersome and requires the participation of related technicians, which not only has low efficiency and flexibility, but also has high offline operation and maintenance costs, for example, if the terminal is sold, the user needs to provide the terminal to an after-sales service center to update the COS in the eSIM card, which is very complicated and costly.

In order to solve the technical problem, the application provides a method for updating the system data of the SIM card. When the update indication message of the target SIM card is detected, at least one piece of update description information can be acquired. Since the update description information may describe an update characteristic of an update file corresponding to the update description information, the update description information may be verified based on system information of the target SIM card. When a certain update description information passes the verification, the update description information is the target update description information, so that a target update file corresponding to the target update description information can be obtained, and the system data in the target SIM card is updated based on the target update file. That is, whether the system data needs to be updated or not can be automatically judged according to the acquired update description information, and when the system data needs to be updated, the corresponding target update file is acquired to update the system data, so that the COS does not need to be updated by the related technical personnel through the operation upgrade script under the research and development environment, the efficiency and the flexibility of updating the system data are improved, and the operation and maintenance cost is also reduced.

Fig. 1 is a schematic structural diagram of a data updating system of a SIM card system according to an embodiment of the present disclosure. The system may be provided in a terminal 100, which may be provided with at least one programmable SIM card 110. As shown in fig. 1, the system may include a Local Profile Administrator (LPA) module 120, an Application Programming Interface (API) 130, and an Open Mobile API (OMAPI) 140 for interacting with the programmable SIM card.

The LPA module 120 may include a Local User Interface (LUI), a profile download sub-module for the programmable SIM card, a profile management sub-module, and an osu (os update) sub-module. The LUI may be configured to provide an interface for interaction between the SIM card system data update system and a user, for example, the LUI may receive a corresponding user operation to enter or end system update, and determine a data source of the current update selected by the user through the LUI; the profile downloading submodule and the profile management submodule can be respectively used for downloading and managing user data such as profiles and the like; the OSU submodule may be configured to update a system in the programmable SIM card, the OSU submodule including at least one system vendor's data parser, the data parser being configured to parse and execute instructions for the system in a manner corresponding to the system vendor.

The call system API130 may be configured to interact with the baseband 150 at the hardware layer, including controlling the baseband 150 to enter or exit an update mode (pass through mod). When the baseband 150 is in the update mode, the baseband 150 may reject other service requests that may be related to the network, such as a network searching service, a data service, or a call service, of the terminal.

The OMAPI140 may be connected to the programmable SIM card 110 located in the hardware layer through a SIM card interface driver 150 based on the international organization for standardization (ISO) 7876 standard, such as a Serial Peripheral Interface (SPI) driver or a 7816 driver located in the kernel layer, so that the LPA module 120 may interact with the programmable SIM card 110, thereby updating system data in the programmable SIM card 110.

Optionally, the SIM card system data updating system may further include the server 200. The server 200 may include a server or a server cluster, and the server 200 may provide the terminal 100 with data related to updating the system data, such as at least one of the update description information and the target update file.

It should be noted that the server 200 may be determined by a preset setting, and may include a server of a system manufacturer, a server of a terminal manufacturer, or a server different from the server of the system manufacturer and the server of the terminal manufacturer.

It should be noted that, in the embodiment of the present application, the LPA module 120 in the terminal 100 is used as a SIM card update module to update system data in the programmable SIM card, but in practical applications, other modules capable of writing data into the programmable SIM card in the terminal 100 may also be used as a SIM card update module, for example, a Near Field Communication (NFC) module. The SIM card update module is not particularly limited in the embodiment of the present application.

The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 2 is a flowchart of a method for updating SIM card system data according to an embodiment of the present disclosure. The method can be applied to a terminal. It should be noted that the method is not limited by the specific sequence shown in fig. 2 and described below, and it should be understood that in other embodiments, the sequence of some steps in the method may be interchanged according to actual needs, or some steps may be omitted or deleted. The method comprises the following steps:

s201, when an update indication message of a target subscriber identity module SIM card is detected, at least one piece of update description information is obtained, and the update description information is used for describing the update characteristics of an update file corresponding to the update description information.

In order to update the system data in the target SIM card in time to ensure that the target SIM card can operate reliably, the terminal 100 may detect an update indication message of the target SIM card through a SIM card update module (such as the LPA module 120 in fig. 1), and in order to facilitate the terminal to determine a summary feature of the current update to determine whether to perform the current update or perform other operations, when the update indication message for the target SIM card is detected, the update description information may be obtained.

Optionally, the SIM card may include system data and user data.

The update indication message may be used to indicate that the system data in the target SIM card may be updated currently. Alternatively, the update indication message may include an update trigger instruction of the target SIM card or a power-on message of the target SIM card.

The update triggering instruction can be used for indicating that the system data in the target SIM card is updated, and the update triggering instruction can be triggered by the user executing preset user operation. When the update indication message includes the update trigger instruction, the terminal 100 may present at least one programmable SIM card to the user through the LUI in the foregoing, and then the user may select any one of the programmable SIM cards, so as to update the system data in the selected programmable SIM card.

The power-on message of the target SIM card may indicate that the target SIM card is currently powered on and started. When the update indication message includes a power-on message of the target SIM card, the terminal may subscribe to the power-on message of the target SIM card in advance (e.g., through the OSU sub-module in the LPA module 120) from a power-on management process in the terminal. Then, when the target SIM card is powered up again (for example, the terminal is powered on), the terminal may acquire a power-up message of the target SIM card sent by the power-on management process.

The update description information may be used to describe an update characteristic of a target update file corresponding to the update description information.

Optionally, the update description information may include a first system vendor identifier and at least one first system version identifier, and may further include at least one of a third system version identifier, an update file path, a system erasure identifier, and a user data erasure identifier.

The first system manufacturer identification is the identification of the system manufacturer corresponding to the update file; the third system version identification is the version identification of the system after the system data is updated based on the update file; the first system version identification is the version identification of the system data which can be updated based on the update file; the update file path may be used to indicate a location of the update file, and the update file path may include a network path pointing to a certain location in the network, or may include a local path pointing to a certain location in the terminal; the system erasure identifier can be used for indicating to erase the system data in the target SIM card, if the update description information includes the system data erasure identifier, it can be shown that the current update is to completely update the system data and needs to erase the system data in the system data, and if the update description information does not include the user data erasure identifier, it can be shown that the current update is to update the system data in a patching manner and does not need to erase the system data in the system data; the user data erasure flag may be used to instruct erasure of user data in the target SIM card, and if the update description information includes the user data erasure flag, it indicates that the user data in the system data needs to be erased, and if the update description information does not include the user data erasure flag, the user data in the system data needs to be erased.

It should be noted that, in practical application, the identifier name of the "system data erasure identifier" may also be determined according to actual needs, as long as the identifier can indicate that the update is a complete update of the system data or a patch update of the system data, that is, whether the system data needs to be erased or not. Of course, the identifier name of "user data erasure identifier" may also be determined according to actual needs, as long as it can be stated through the identifier whether the user data needs to be erased in the update.

Alternatively, the update description information may be determined in advance according to a corresponding update file, for example, determined by a technician who generates the update file, or determined by machine mining or machine learning, etc., according to the update file.

For at least one first system version identification, when the update file is generated, whether the update file has conflict with system data of each possible version can be judged. And if the system data of a certain version does not conflict with the update file, determining the version identification of the system data of the certain version as the first system version identification, so that the system data with the first system version identification can be updated based on the update file.

If the system data in a certain SIM card is updated twice in the history, the version identifier includes 000, 001 and 002, and the current update needs to erase the system data, no matter how the previous two updates happen, no conflict will occur with the current update, that is, the system data of the 000, 001 and 002 versions can be updated this time. Therefore, for the update, the third system version identifier in the update description information may be set to 003, the first system version identifier may be set to 000, 001, and 002, and the system erasure identifier may be set to erase _ cos, which indicates that the system in the target SIM card needs to be erased.

If the system data in a certain SIM card is updated twice in the history, the version identifier includes 000, 001 and 002, the system data is not erased in the current update, and the current update and the previous updates are both updates based on different characteristics in the previous version system, no conflict will be generated with the current update no matter how the previous updates are, that is, the system of the 000, 001 and 002 versions can perform the current update. Therefore, for the update, the third system version identification in the update description information may be set to 003, the first system version identification may be set to 000, 001, and 002, and the system erasure identification may be set to erase _ cos.

If the system in a certain SIM card is updated twice in the history, the version identification comprises 000, 001 and 002, the system data is not erased in the updating, and the updating and the previous updating are both updating based on at least the same characteristic in the previous version system, so the updating can be performed only based on the system data of the 002 version. Therefore, for the update, the third system version identifier in the update description information may be set to 003, the first system version identifier may be set to 002, and the system erasure identifier may be set to null, that is, system data does not need to be erased.

It can be seen that by setting at least one first system version identifier, it can be ensured that no matter which version the system data before updating is, as long as the system data of the version does not conflict with the current update file, the system can be updated through the update file, so that in the using process of the terminal, the system does not need to be updated one by one according to the release order of each version in the history, but the terminal can directly upgrade to the latest version across at least one intermediate version, or can perform version rollback. For example, some update description information includes a third system version identification of 003, first system version identifications of 000, 001, and 002, and a system version identification of 001 in some programmable SIM card. If the system in the programmable SIM card is updated to the 002 version and then to the 003 version according to the update method in the prior art. However, in the method for updating the system data of the SIM card provided in the embodiment of the present application, since the system version identifier in the programmable SIM card is one of the first system version identifiers, the system in the programmable SIM card can be updated directly based on the update file corresponding to the description information, and after the update is completed, the version identifier of the system can be 003, so that the process of updating the system data from the 001 version to the 002 version is omitted. Therefore, the method for updating the system data of the SIM card provided by the embodiment of the application not only obviously reduces the time taken for updating and improves the updating efficiency, but also avoids unnecessary erasing of the programmable SIM card in the updating process and prolongs the service life of the programmable SIM card.

In addition, if the update description information includes a system data erasure identifier, it can be shown that the update is to completely update the system data (i.e., upgrade), and the system data needs to be erased; if the update description information does not include the system data erasure identifier, it can be shown that the update is to update the system data in a patching manner (i.e., update), and the system data does not need to be erased.

It should be noted that the system version identifier may be used to indicate the version of the system data. The system version identifier may include at least one hierarchical sub-identifier, for example, the system version identifier may include a primary version identifier and a secondary version identifier, where the primary version identifier is a system identity number (ID) and the secondary version identifier is a platform ID.

It should be noted that the first system manufacturer identifier, the system erasure identifier and the user data erasure identifier may be represented by character strings.

The update file path may be used to indicate a location where the update file is located, and the update file path may include at least one of a first network address pointing to the first preset server and a first local address pointing to the home terminal of the terminal. By setting the update file path, the terminal can conveniently and flexibly acquire the update file according to the update file path instead of acquiring the update file from the system manufacturer, decoupling of system data and the system manufacturer is realized, and flexibility of updating the system data is further improved.

And the update file can be used for updating the system data in the programmable SIM card.

Alternatively, the update file and the update description information may be corresponding. The update file may include an APDU write instruction set, a version identification update instruction set, and a power-on resume instruction set; when the update description information includes a system data erasure flag, the update file may further include a system erasure instruction set; when the updating description information comprises a user data erasing identification, erasing a command set by the user data; in addition, the update file may also update the mode setting instruction set. Alternatively, the update file may further include an update mode setting instruction set only when the APDU write instruction set, the version identification update instruction set, the power-on restart instruction set, and the system erase instruction set are included.

The APDU write instruction set may be used to write APDU data into the target SIM card, and the APDU write instruction set may include at least one APDU instruction, and each APDU instruction may be used to update at least one characteristic in the system data; the version identification updating instruction set may be used to update the system version identification in the target SIM card, including updating the system version identification before updating to a third system version identification included in the update description information, where the version identification updating instruction set may include at least one version identification updating instruction; the re-power-on instruction set may be used to instruct to re-power on the target SIM card, such as instructing to re-start the terminal, and the re-power-on instruction set may include at least one re-power-on instruction; the system erasing instruction set can be used for erasing system data in the target SIM card, and the system erasing instruction set can comprise at least one system erasing instruction; the user data erasing instruction set can be used for erasing the user data in the target SIM card, and the user data erasing instruction set can comprise at least one user data erasing instruction; the update mode setting instruction may instruct the baseband of the terminal to enter an update mode, and the update mode setting instruction set may include at least one update mode setting instruction, wherein when system data or user data needs to be erased for system data update, system function of the target SIM card may be damaged, and thus the baseband may be instructed to enter an update module.

Alternatively, the data format of the update description information may be set in advance. For example, an update description information may be as shown in table 1 below. In table 1 below, the first line "vendor _ ID" may be a first system vendor identifier, the second line "target _ cos _ version" may be a third system version identifier, the third line "allow _ cos _ version" may be a first system version identifier, the fourth line "erase _ cos _ segment" may be a system erase identifier, and the fifth line "erase _ profile _ segment" may be a user data erase identifier.

TABLE 1

It should be noted that, in the embodiment of the present application, only the update description information is introduced in table 1, and table 1 does not set any limit to the specific content and data format of the update description information.

When the terminal acquires the update description information, the terminal may acquire the update description information according to the update description information address. The update description information address may be obtained by receiving user submission or setting in advance, and the update description information address may include a second network address pointing to a second preset server or a second local address pointing to the terminal home terminal. And when the update description information address comprises the second network address, the update description information can be acquired in an OTA mode.

It should be noted that the first preset server may store the update file, the second preset server may store the update description information, and the first preset server and the second preset server may be different server modules in the same server or different servers in the same server cluster, or of course, may also be the same server module in the same server or the same server in the same server cluster. In addition, when the update description information is the same file as the update file, the first local address may be the same as the second local address.

It should be noted that the first predetermined server or the second predetermined server may be a server of a system manufacturer, a server of a terminal manufacturer, or a server different from the server of the system manufacturer and the server of the terminal manufacturer. That is, in the embodiment of the present application, sources of the update description information and the update file are not limited, and the terminal may flexibly obtain the update description information according to the update description information address and obtain the target update file according to the update file path, instead of obtaining the update file and the update description information only from a system manufacturer of the target SIM card (or called a system data manufacturer), so that decoupling of system data in the SIM card and the system data manufacturer can be achieved, and flexibility of updating the system is further improved.

In addition, when the update description information includes the system data erasure flag, the system data erasure prompt information may be output, and when the update description information includes the user data erasure flag, the user data erasure prompt information may be output.

The system data erasure prompting information can be used for prompting that the system data is to be erased, and the user data erasure identifier can be used for prompting that the user data is to be erased.

S202, based on the system information of the target SIM card, the updating description information is verified.

Since the update files corresponding to different update description information may or may not be compatible with the system data in the target SIM card, the update description information may be checked based on the system information of the target SIM card in order to ensure that the system data can be successfully updated.

The system information of the target SIM card may be used to indicate at least one system attribute of the target SIM card. Optionally, the system information may include a second system vendor identifier and a second system version identifier of the system in the target SIM card.

The system information of the target SIM card may be obtained from the target SIM card, or the system information may also be obtained from a preset storage location where the system information is stored.

When the update description information is verified based on the system information of the target SIM card, the second system vendor identifier included in the system information may be compared with the first system vendor identifier included in the update description information, and the second system version identifier included in the system information may be compared with at least one first system version identifier included in the description information. Because the first system manufacturer identifier is the identifier of the system manufacturer corresponding to the update file, and the first system version identifier is the version identifier of the system data that can be updated based on the update file, when the first system manufacturer identifier is the same as the second system manufacturer identifier, it can be stated that the manufacturer corresponding to the update file is consistent with the manufacturer of the system in the target SIM card, and when any one of the at least one first system version identifier is the same as the second system version identifier, it can be stated that the current system version in the target SIM card is the same as the system version to which the update file is directed. Therefore, when the first system manufacturer identifier in the update description information is the same as the second system manufacturer identifier, and any first system version identifier in the update description information is the same as the second system version identifier, it is determined that the update description information passes verification, and the subsequent steps can be continuously executed to update the system data in the target SIM card, otherwise it is determined that the verification fails, and the system data is not updated. That is, on one hand, the terminal can compare the first system manufacturer identifier with the second system manufacturer identifier of the target SIM card, so as to ensure that the system data of the target SIM card is updated through the update file corresponding to the manufacturer of the system in the target SIM card, thereby being capable of updating the system data of different manufacturers; on the other hand, the at least one first system version identification is compared with the second system version identification in the target SIM card, so that the system data of the target SIM card is ensured to be updated through the update file which is adaptive to the system data in the target SIM card, and whether the programmable SIM cards with the system data of different versions are updated based on the update file can be flexibly and accurately controlled.

For example, in the obtained update description information, the vendor _ ID field is 123, the allow _ system _ version field is 000, 001, and 002, and the second system vendor identifier of the target SIM card is 123 and the second system version identifier is 001. Since the second system vendor identifier is the same as the vendor _ ID, it can be determined that the vendor corresponding to the target update file is consistent with the vendor of the system in the target SIM card. Since the second system version is identified as one of the allow _ system _ versions, it may be determined that the current system version in the target SIM card is the same as the system version for which the target update file is intended.

It should be noted that the first system version id may include multiple levels of sub first system version ids, and correspondingly, the second system version id includes multiple levels of sub second system version ids. By setting the multi-level version identification, more detailed updating and checking of the system data can be realized, and the accuracy of updating and checking the system data can be further improved.

For example, the first system version id includes two levels of sub-first system version ids, the second system version id also includes two levels of sub-second system version ids, and two adjacent levels of sub-first system version ids or third sub-system version ids may be separated by a preset separation symbol (e.g., "). If the first system version id includes 000.0, 000.1, 001.0, 001.3 and 002.2 and the second system version id is 001.0, the second system version id is one of the first system version ids.

Optionally, since more than one update file may be included to be suitable for the update only from the aspect of compatibility with the current system data, the version that may be updated based on different update files may be different, and if the update file is updated to an older version, the update may need to be performed again, which results in a long update time and multiple erasures performed on the programmable SIM card. Therefore, in order to realize cross-version updating, significantly reduce the time taken for updating, improve the updating efficiency, avoid unnecessary erasing of the programmable SIM card in the updating process, and improve the service life of the programmable SIM card, when the update description information further includes a third system version identifier, for any update description information, when the first system manufacturer identifier in the update description information is the same as the second system manufacturer identifier, any first system version identifier in the update description information is the same as the second system version identifier, and the third system version identifier in the update description information is higher than the third system version identifier included in other update description information in at least one update description information, it is determined that the update description information passes verification.

For example, the system version of the current system data in a certain SIM card is 001, the first system version identifiers in the obtained update description information 1 and the update description information 2 both include 001, but the third system version identifier in the update description information 1 includes 002, the third system version identifier in the update description information 2 includes 003, and the system version 003 is higher than the system version 002, so that it can be determined that the update description information 1 passes the check, thereby facilitating the direct update from 001 to 003.

It should be noted that the manner of determining the comparison size between the system version identifiers may be determined according to the form of the system version identifiers, where when a certain system version identifier is larger, the version of the system data corresponding to the system version identifier is also higher. For example, the system version identifier is represented by a number, and a larger number represents a higher corresponding version; alternatively, the system version identification is represented by letters, the letters going from a to z, and the corresponding version going from high to low.

Optionally, to prevent version rollback, when the first system vendor identifier in the update description information is the same as the second system vendor identifier, any first system version identifier in the update description information is the same as the second system version identifier, and a third system version identifier in the update description information is higher than the third system version identifier and the second system version identifier included in other update description information in the at least one update description information, it is determined that the update description information passes verification. Or, for version rollback, when the first system vendor identifier in the update description information is the same as the second system vendor identifier, any first system version identifier in the update description information is the same as the second system version identifier, a third system version identifier in the update description information is higher than third system version identifiers included in other update description information in at least one update description information, and the third system version identifier in the update description information is lower than the second system version identifier, determining that the update description information passes verification.

S203, when the updating description information passes the verification, a target updating file corresponding to the target updating description information is obtained.

If a certain update description information passes the verification, the target update file corresponding to the target update description information can be used for updating the data in the target SIM card, so that the terminal can acquire the target update file.

The target update description information is the update description information which passes the verification in the acquired at least one update description information, and the target update file is the update file corresponding to the target description information.

The target update file may be obtained by at least one possible implementation of:

in a possible implementation manner, since the update file path may indicate a location where the target update file is located, and may include at least one of a first network address pointing to the first preset server and a first local address pointing to the terminal home terminal, when the update description information includes the update file path, the target update file may be obtained based on the update file path. When the update file path includes a first network address pointing to a first preset server, the target update file may be acquired from the first preset server in an OTA manner, and when the update file path includes a first local address pointing to a terminal home terminal, the target update file may be acquired from the terminal home terminal.

In another possible implementation manner, when the update description information does not include the update file path, the update description information may be carried in the target update file, and the target update file may be directly obtained; or, the file in which the update description information is located and the target update file may belong to the same file, so that the target update file may be obtained from the file.

Optionally, at least one update file may be in the same update file set, and each update file may correspond to one update description information, and then an update file path carried in the update description information may be a path where the update file set is located, so that the update file set may be obtained from the update file path, and a target update file corresponding to the target update description information may be obtained from the update file set.

And S204, updating the system data in the target SIM card based on the target update file.

The terminal can acquire and execute the instruction included in the target update file, so that the update of the system data in the target SIM card is completed.

Optionally, referring to fig. 3, a flowchart for updating system data in a target SIM card based on a target update file provided in an embodiment of the present application includes:

s2041, opening a logic channel for updating the target SIM card.

The programmable SIM card may include a plurality of different logic channels, and different logic operations may be performed through different channels, so that the terminal may open (through the LPA module 120) a logic channel for updating system data, so as to facilitate subsequent updating operations.

S2042, execute the update mode setting instruction set, and instruct the baseband of the terminal to enter the update mode.

Since part of functions of the target SIM card may be temporarily unavailable, for example, the network cannot be used, during the process of updating the system data in the target SIM card, in order to avoid that other applications in the terminal send service requests related to the network to the baseband during the process of updating the system, the terminal may execute an update mode setting instruction set, thereby instructing the baseband to enter the update mode.

It should be noted that, in practical applications, S2042 may not be executed, or S2042 may be executed only when system data or user data needs to be erased.

S2043, executing at least one of the system data erasure instruction set and the user data erasure instruction set, thereby erasing at least one of the system data and the user data in the target SIM card.

When the system data is updated to a smaller extent (i.e., updated), such as patched, the system data may not be erased; when the system data is updated to a greater extent (i.e., updated), for example, the target SIM card supports new services such as a fifth generation mobile communication technology (5th generation mobile networks), and software repair or other failures of the system data are performed, the system data may be erased.

In addition, when updating system data, the updated system data may not be compatible with user data, and thus, the user data may be erased.

S2044, the APDU writing instruction set is sent to the target SIM card, and therefore at least one characteristic of the system data in the target SIM card is updated.

In a possible implementation manner, the terminal may analyze the APDU write-in instruction set through the SIM card update module to obtain at least one APDU write-in instruction, sequentially send the at least one APDU write-in instruction to the target SIM card, and the target SIM card executes the APDU write-in instruction. Or, in another possible implementation manner, the terminal may divide the APDU write instruction set into a plurality of data packets with a preset size through the SIM card update module, send the plurality of data packets to the target SIM card, where the target SIM card obtains the APDU write instruction set based on the plurality of data packets, and then decrypt the APDU write instruction set to obtain the APDU write instruction including at least one APDU write instruction. Or, in another possible implementation manner, the terminal obtains, from the update file, a plurality of data packets with preset sizes obtained by dividing the APDU write instruction set in advance, so that the plurality of data packets may be directly sent to the target SIM card. The terminal may send an execution completion notification message to a system data module in the terminal after executing the APDU write instruction set.

It should be noted that the preset size of the data packet may be determined in advance, for example, the preset size may be 255kb (kilobyte), and each data packet may be encrypted in advance by a manufacturer of the system data or a manufacturer of the target SIM card and may be decrypted by the SIM card.

For example, in the system shown in fig. 1, the LPA module 120 in the terminal may send the parsed APDU write command to the target SIM card through the OMAPI140 and the SIM card interface driver 150.

It should be noted that the manner of parsing the APDU write command set may be determined in advance according to a system manufacturer of the target SIM card or a manufacturer of the target SIM card.

And S2045, executing the version identification updating instruction set, and updating the system version identification in the target SIM card into a third system version identification carried by the updating description information.

The terminal may execute the version identifier update instruction set when receiving the execution completion prompt information, that is, when determining that the target SIM card has executed the APDU write instruction set, where the executing includes replacing the second system version identifier with a third system version identifier included in the update description information.

Optionally, if the target update description information does not include the third system version identifier, the terminal may update according to the preset version identifier generation rule and the second system version identifier, generate the third system version identifier, and replace the second system version identifier with the third system version identifier.

The preset version identifier generation rule may be determined in advance, for example, when the system version identifier is represented by a number, the current system version identifier may be increased by 1 to obtain a new system version identifier.

As can be seen from the foregoing, since the target update file includes the APDU write instruction set, the version identifier update instruction set, and the power-on resuming instruction set, and may further include at least one of the system erase instruction set, the user data erase instruction set, and the update description information may include at least one of the system data erase identifier and the user data erase identifier, when updating the system data in the target SIM card, it may be determined whether the update is update or upgrade according to the target update description information, whether the system data or the user data needs to be erased first, and the corresponding manner of updating the system data may include the following several cases:

That is, by splitting the update file into a plurality of instruction sets and combining the update description information, the instruction sets can be dynamically increased, decreased and arranged according to the actual update requirements, the need for erasing the system data (update) and the need for erasing the update of the system data (update) can be simultaneously met, and the flexibility of updating the system data is further improved.

For example, one sort of combined update instruction may be as follows:

wherein, "erase _ cos" is the system data erase instruction set, "erase _ profile" is the user data erase instruction set, "passthregh" is the update mode setting instruction set, "first segment" and "second segment" are the APDU write instruction set, "write cos version" is the version identification update instruction set, and "reset sim power" is the power-on instruction set again.

Optionally, after the system data in the target SIM card is updated this time, it may be further determined whether a new target update file exists, if so, the system data is updated based on the new target update file continuously according to the steps similar to those described above, otherwise, the pairing is ended.

And acquiring new updating description information again according to the steps similar to the steps, and checking the new updating description information. If the new update description information is acquired and verified, it can be determined that a new target update file exists, otherwise, it can be determined that a new target update file does not exist.

The following describes exemplary workflow of the software and hardware of the terminal 800 in connection with capturing a photo scene.

When the touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into an original input event (including touch coordinates, a time stamp of the touch operation, and other information). The raw input events are stored at the kernel layer. And the application program framework layer acquires the original input event from the kernel layer and identifies the control corresponding to the input event. Taking the touch operation as a touch click operation, and taking a control corresponding to the click operation as a control of a camera application icon as an example, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera drive by calling a kernel layer, and captures a still image or a video through the camera 193.
