Description

USAT application matching management method, terminal, USIM and system

Technical Field

The present disclosure belongs to the field of communication technologies, and in particular, to a USAT application matching management method, a terminal, a USIM, a USAT application matching management system, a computer device, and a computer-readable storage medium.

Background

The USIM (Universal Subscriber Identity Module) card is a continuation and progress of the SIM card used in the UMTS (Universal Mobile Telecommunications System) network, and is used to store user Identity information and personal data, ensure the security of accessing Mobile network services, and perform user identification and user authorization when a user accesses the Mobile network services by using necessary functions and data, so as to implement the requirement that the System network can represent and identify user applications.

With the development of USIM service demand, in order to enhance the initiative of USIM cards in communication with terminals, a USAT (USIM Application Toolkit) technology has been introduced. The USAT technology is based on the original passive operation mode of the SIM card, and adds the new active operation capability of the USIM card, that is, allows the application and service in the USIM card to actively perform interactive operation with the mobile phone terminal. However, USAT application matching is a new function developed in the 4G era, and a USIM card can be restricted to be used on a specific terminal through the USAT function, that is, only when the USIM allows the terminal to be used, the USIM can be authenticated and normally used, and for terminals that are not allowed to be used, the USIM does not authenticate. In order to implement the function, the USIM presets the range of terminals allowed to be used, performs matching verification before an authentication command, that is, initiates a USAT session, obtains the IMEI (International Mobile Equipment Identity) or IMEISV (International Mobile Equipment Identity Software Version) of a terminal through a command of the provider Local Information, checks whether the terminal or IMEISV is in a list of terminals allowed to be used, and does not perform authentication on the IMEI of terminals not in the list. The USIM may record the result of each matching verification as necessary, such as whether the verification is passed or not, the IMEI or IMEISV that failed the verification, and store the result in a corresponding Elementary File EF (Elementary File in the File system of the integrated circuit card).

In the prior art, USAT application matching belongs to a set function, a USIM card performs presettability setting before being issued to a user, and the setting includes whether the USAT application matching function is enabled or not, and if so, the terminal range of use is correspondingly allowed. After the preset setting is completed, the requirement of the USIM card in the aspect is determined, and the USIM card adopts the determined setting to carry out matching verification on the terminal using the USIM card. However, with the mobile service scenario, especially the gradual diversification and complication of the M2M service scenario, the service requirements are likely to be in the middle of changing, the management requirements between the cards are also changed accordingly, for example, the matching performance can be changed from activation to deactivation, the matching range can be widened, and the like, and a single fixed setting cannot meet the flexible and dynamic change more and more, so a new technical scheme is urgently needed to make a certain adjustment on the implementation manner of USAT application matching.

Detailed Description

In order to make the technical solutions of the present disclosure better understood by those skilled in the art, the present disclosure is further described in detail below with reference to the accompanying drawings and examples.

In which the terminology used in the embodiments of the disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in the disclosed embodiments and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

In the following, some terms in the present application are explained to facilitate understanding by those skilled in the art:

UICC (Universal Integrated Circuit Card), which may include multiple logical applications, SIM (Subscriber Identity Module), USIM (Universal Subscriber Identity Module), and other applications (e.g., electronic wallet, etc.). And the terminal and the UICC carry out data interaction through a Cu interface. An STK (SIMTOOL KIT, subscriber identity card intelligent toolkit)/USAT protocol layer is introduced into a protocol stack of a Cu interface, the STK/USAT protocol layer provides a service mechanism on the basis of service provided by a transport layer, USIM application is allowed to interact and operate with a terminal supporting the mechanism, the USIM can actively require the terminal to execute certain operation, and an STK/USAT instruction set is a basis and a main mode for realizing service of a telecommunication intelligent card through the terminal.

With the USAT mechanism, more applications can be implemented on the USIM. Compared with terminal application with more functions and stronger man-machine interaction, the USIM application also has advantages, such as being more suitable for services with strong security. Therefore, in practical applications, more and more schemes need to combine the USIM application and the terminal application so as to exert the advantages of the USIM application and the terminal application together to obtain better effects. The USAT application matching is a new function developed in the 4G era, and the USIM card can be restricted to be used on a specific terminal through the USAT function, that is, only when the USIM allows the use of the terminal, the USIM can be authenticated and normally used, and for a terminal which is not allowed to be used, the USIM does not authenticate.

The most typical application scenario of USAT application matching is M2M service, and M2M service has certain specificity compared with personal service, such as obvious difference in service mode, tariff management and the like, so that SIM cards provided for M2M service bring various problems if applied to personal service, and the problem of applying M2M cards to specific M2M terminals can be realized by using USAT application matching function, and the phenomenon of being transferred to personal terminals is avoided. However, when the USAT application matching is used, the determined settings are adopted for matching verification, and with the gradual diversification and complication of mobile service scenes, particularly M2M service scenes, service requirements are likely to be in the middle of change, corresponding changes can be made to the management requirements between the set cards, a single fixed setting is increasingly unable to meet flexible and dynamic changes, and certain adjustment needs to be made on the implementation mode of the USAT application matching.

The following describes the technical solutions of the present disclosure and how to solve the above technical problems in specific embodiments. 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. 1 is a flowchart of a method for managing matching of universal subscriber identity module USIM application toolkit USAT applications provided in an embodiment of the present disclosure, and is applied to a terminal, as shown in fig. 1, the method includes:

step S101: receiving a first command sent by a USIM, wherein the first command is a command generated by the USIM after receiving a requirement for changing USAT application matching, acquiring the information of the requirement for changing the time and according to the information of the requirement for changing the time;

step S102: acquiring a requirement of USAT application matching change according to the first command, and performing initialization operation between the machine and the card according to the requirement of the USAT application matching change, so that the USIM performs matching verification on the terminal when the initialization operation between the machine and the card is performed on the terminal, and completes the USAT application matching change after the verification is passed.

Before a USIM with a USAT application matching function is issued to a user, an operator or an operator can perform presetting on the USIM card, the setting comprises whether the USAT application matching function is enabled, if the USAT application matching function is enabled, a terminal range which is allowed to be used is further set, after the presetting is completed, the requirement of the USIM card on the application matching function is determined, and the USIM card performs matching verification on the terminal which uses the USIM card afterwards by adopting the determined setting. In some cases, however, a server, a user or an operator applied in the USIM or the terminal may generate a need to change settings matched with the USAT application according to a service policy, and make corresponding changes to the management requirements between the cards, such as matching may be changed from enabled to disabled, matching range may be relaxed, etc., after the request to change the USAT application matching is generated, the settings configured for the USAT application matching are changed, and the USIM acquires information of related change requirements, which may include a change type and a change validation setting requirement, by acquiring content changes of the settings matched with the USAT application, including data changes of related files matched with the USIM application in the USAT application, or setting related parameters, and acquiring information of the related change requirements, which may include the change type and a change validation setting requirement, wherein the change type is analyzed and processed according to the changes of the related data and parameters, from which the corresponding change type is parsed, if the specific change type cannot be determined, or the change type is unknown, it may be temporarily set to be unknown, and then the USIM provides the occurrence of an event to the terminal through an extended proactive command, wherein, the requirement of setting change can be included, the terminal analyzes after receiving the instruction to obtain the requirement of USAT application matching change, the requirement of change type and change effective setting can be included, the judgment is carried out according to the change requirement, if necessary, starting necessary updating commands, performing initialization operations (refreshing) between the machine card, including the terminal restarting, the terminal restarting after closing the USIM card, or reminding the user to plug the USIM card again, performing initialization operation with the USIM card again, triggering authentication of the USIM for matching the USAT application of the terminal again, and performing the authentication according to the content and parameters after the setting matched with the USAT application is changed so as to enable the changed setting to be effective.

The embodiment of the disclosure is based on an STK/USAT mechanism, on the premise of observing a basic interaction mechanism between the machine card, firstly, a proactive command needs to be extended, a USAT application matching setting Change event is provided for a terminal, and the extended newly-added command can be named as Pair State Change, namely, a first command. And after receiving the first command, the terminal acquires the requirement of USAT application matching change from the command, and verifies the matching with the USIM according to the requirement to complete the USAT application matching change. The extended Pairing State Change command is as follows in Table 1:

table 1: extended Pairing State Change Command Structure parameters

Note:

m, O respectively refers to optional and optional; min refers to whether there is a minimum length requirement, and Y is an abbreviation for Yes.

The change type is an extended data object, and optionally represents the type of the change of the current USAT application matching relationship, such as the starting/releasing of the matching relationship and the expansion/reduction of the matching range. The starting/releasing of the matching relation respectively represents the requirement of the USIM on whether the USAT application matching relation is started, the expansion/reduction of the matching range respectively represents the expansion and reduction of the terminal list range allowed to be used by the USIM, and the specific codes are shown in the table above;

the change validation setting is an extended data object, optionally, the time that the USAT application matching relation expected by the USIM takes effect at this time is represented, and the change validation setting is divided into two types of real-time validation and delayed validation. The real-time validation request terminal immediately matches with the changed requirement to conduct matching verification again, and the delayed validation request terminal can temporarily not conduct matching verification again according to the changed requirement.

As shown in table 1, the change type in table 1 is an extended data object, which indicates the type of a requirement for changing the USAT application matching, and includes activation, deactivation, and adjustment of the matching range of the USAT application matching; the modification type is confirmed after the USIM analyzes the content of modification of the USAT application matching configuration written by the server with authority or the user according to the service policy, besides the above type, the modification type also comprises other requirements which cannot specify the specific type, the USIM provisionally sets the modification type as the condition that the modification type is unknown, when the subsequent matching verification is carried out, the verification is directly carried out according to the data and parameters of the USAT application matching configuration in the USIM card, and the modification of the USAT application matching configuration can be provided to the USIM in a remote or local setting mode or the like.

judging whether the first command contains change effective setting;

if the change validation setting is delayed to be valid, or the first command does not contain the change validation setting, the terminal performs machine-card initialization operation according to the USAT application matching change condition under a preset condition, so that the USIM performs matching verification on the terminal according to the USAT application matching change condition when performing machine-card initialization operation on the terminal.

The terminal analyzes after receiving the first command, and obtains the requirement about the current change in the command, such as the type of the requirement for changing the USAT application matching;

the terminal analyzes the command qualifier b1 from the first command (in table 1) to obtain whether the command contains the change validation setting, if yes, the terminal judges whether the command requires real-time validation, if yes, or the first command does not contain the change validation setting, the terminal executes the real-time validation requirement, sends a second command (FETCH command) to the USIM, and enables the USIM to obtain the condition of the terminal about refresh (initialization operation between machine cards); the USIM receives the FETCH command, sends a REFRESH command to the terminal and requires the terminal to REFRESH; the terminal executes a REFRESH command and executes the REFRESH command, and in the process of initialization operation between the machine card and the USIM card according to the situation that USAT application matching is changed, if the application is changed to adjust the matching range of the USAT application matching, the terminal can check whether the files of the terminal list allowed to be used are updated or not, so that the condition that the matching verification of the USIM card on the terminal is changed according to the USAT application matching is ensured, namely, the matching verification of the terminal and the USIM card is carried out again according to the requirement after the required change is finished;

if the real-time validation is not required, the change is delayed to take effect, and the USIM waits for the opportunity to carry out the matching verification again under the preset condition (such as terminal restart);

and if the first command does not comprise the change validation setting, the terminal executes the real-time validation requirement, performs the same operation as the command requiring the real-time validation, sends a second command (FETCH command) to the USIM, and performs subsequent actions.

According to the embodiment of the application matching setting method and the terminal, the terminal obtains the USAT application matching setting change event, the initialization operation between the machine and the card is carried out according to the event, and the matching verification of USIM dominance can be triggered again, so that the changed matching setting plays a role in real time, and the requirements brought by the change of a service scene or a mode are met.

The embodiment of the disclosure provides a method for realizing timely response to the matching requirement change of a service by a USIM through strengthening USAT application matching management. The concept definitions of change types, change effective settings and the like are provided, the data objects are expanded according to the concept definitions, new active instructions are additionally added, the function, structure and parameter definitions of the active instructions are defined, and the requirements of interaction processes and rules of the USIM and the terminal are stipulated after the USIM strengthens USAT application matching dynamic management. The USAT application matching function flexibility setting is realized, the dynamic property, the flexibility and the real-time property of the USIM function are improved, the management capability of the relation between the USIM and the terminal is improved, and a necessary premise is opened for realizing more management functions.

Fig. 2 is a flowchart of a universal subscriber identity module USIM application toolkit USAT application matching management method provided in a second embodiment of the present disclosure, which is applied to a USIM, and as shown in fig. 2, the method includes:

step S201: when a requirement for changing USAT application matching is received, acquiring information of the change requirement;

step S202: generating a first command according to the information of the current change requirement;

step S203: sending the first command to a terminal, so that the terminal acquires a requirement of USAT application matching change according to the first command and performs initialization operation between the machine and the card according to the requirement of the USAT application matching change;

step S204: and when the terminal carries out initialization operation between the machine and the card, carrying out matching verification on the terminal, and finishing the change of USAT application matching after the verification is passed.

After a USIM or a server, a user or an operator applied in a terminal generates a requirement for changing the USAT application matching setting according to a service policy, the change requirement is provided to the USIM in a remote or local setting mode and the like, and local file updating of the USIM is carried out in a machine-card interaction mode and the like, so that the USIM can carry out matching verification on the terminal according to the requirement after the USAT application matching change. The USIM generates a first command after receiving a requirement for changing USAT application matching, where the format of the command is as in table 1 in the first embodiment, and sends the generated command to the terminal, so that the terminal performs initialization between the set and the card according to the requirement of the command (the initialization between the set and the card is an existing mature technology and is not described here in detail), and the USIM performs matching verification on the terminal again, so that the setting change of USAT application matching is timely or effective as required.

After a requirement for changing the USAT application matching is generated, a server, a user or an operator applied in a USIM or a terminal may change the setting of the USAT application matching configuration, and the USIM acquires information of a relevant change requirement by acquiring a content change of the setting matched to the USAT application, including a data change such as updating of a relevant file matched to the USAT application in the USIM, or a setting of a relevant parameter, where the information of the change requirement may include a change type and a change validation setting requirement, and the change type is analyzed and processed by the USIM according to the change of the relevant data and the parameter, and a corresponding change type is analyzed from the change type, and if a specific change type cannot be determined or the change type is unknown, the change type may be temporarily set as unknown.

The type of requirement to change the USAT application match is generated by the authority according to the business policy and provided to the USIM. In the process, files in the USIM may be updated and corresponding parameters may be changed. And the USIM judges the type of the requirement for changing the USAT application matching according to the updating of the file or the change of the corresponding parameter, and if the type cannot be judged, the USIM is determined to be unknown.

if yes, adding a change effective setting when generating the first command;

The USIM presets a terminal range allowed to be used, performs matching verification before an authentication command, namely initiates a USAT session, obtains the IMEI or IMEISV through a provision Local Information command, checks whether the IMEI or IMEISV is in a terminal list allowed to be used, and does not perform authentication on terminals which are not in the list. The USIM may record the result of each matching verification, such as whether the verification is passed, the IMEI or IMEISV that failed the verification, and the like, as necessary, and store the result in the corresponding file EF.

The USIM judges whether the acquired change requirement information contains change effective setting or not, and if so, the USIM directly adds the change effective setting into the command according to the requirement; if not, inquiring a basic file EF storing the matching verification result to obtain the matching verification result of the current terminal; and judging the effective setting of the change according to the matching verification result of the current terminal and the acquired type of the requirement for changing the USAT application matching, wherein the effective setting of the change comprises real-time effect and delayed effect. And when the USIM can not obtain the change effective setting, the subsequent command does not contain the change effective setting content.

And judging the effective setting of the change according to the matching verification result of the current terminal and the acquired type of the requirement for changing the USAT application matching, putting the effective setting of the change into a first command, so that the terminal performs matching verification with the USIM according to the command requirement, and completing USAT application matching management.

The embodiment of the disclosure mainly aims at the requirement of the USAT application matching setting change generated in the service evolution process, realizes the timely response to the change requirement by reinforcing the management of the USIM to the function, and improves the dynamic property and the flexibility of the function.

step S2: the USIM provides a change requirement to the USIM in a remote or local setting mode and the like, and the USIM acquires the change requirement and determines a change type;

step S3: the USIM determines whether the acquired change requirement contains a change validation setting, if not, performs subsequent steps S4 and S5, and if so, goes to step S6;

step S4: the USIM inquires a basic document EF storing the matching verification result to obtain the matching verification result of the current terminal;

step S5: the USIM judges the effective setting of the current change by combining the matching verification result of the current terminal and the change type acquired before, such as the following various conditions;

when the matching is started, the matching takes effect in real time;

when the matching is released, if the matching verification of the current terminal fails, the terminal takes effect in real time; if the matching verification of the current terminal passes, the current terminal takes effect after delaying;

when the matching range is expanded, if the matching verification of the current terminal fails, the terminal takes effect in real time; if the matching verification of the current terminal passes, the current terminal takes effect after delaying;

when the matching range is reduced, the current terminal matching verification fails, and then the verification takes effect after being delayed; if the matching verification of the current terminal passes, the terminal takes effect in real time;

if the possible USIM can not obtain the change effective setting, the subsequent command does not contain the change effective setting content;

step S6: the USIM generates a Pair State Change command according to the Change type and the Change effective setting, sends the Pair State Change command to the terminal and provides the USAT application matching Change event occurrence and requirement for the terminal;

step S7: the terminal analyzes the command after receiving the command, and obtains the requirement about the current change in the command, such as the change type;

step S8: the terminal analyzes the command qualifier b1 from the command to obtain whether the command contains the change effective setting, if not, the subsequent step S10 is carried out; if yes, judging whether the command requires real-time validation, if not, performing step S9, and if so, performing the subsequent step S10;
