Translated fromChinese技术领域technical field
本公开属于通信技术领域，具体涉及一种USAT应用匹配实现方法，一种USIM，一种终端，一种计算机设备，以及一种计算机可读存储介质。The present disclosure belongs to the field of communication technologies, and in particular relates to a method for implementing USAT application matching, a USIM, a terminal, a computer device, and a computer-readable storage medium.
背景技术Background technique
USIM(Universal Subscriber Identity Module，通用用户识别模块)卡是UMTS(Universal Mobile Telecommunications System，通用移动通信系统)网络中使用的SIM(Subscriber Identity Module，用户标识模块)卡的延续与进步,用于存储用户身份信息和个人数据，保障接入移动网络服务的安全，可以利用必要的功能和数据在用户访问移动网络服务时进行用户识别和用户授权，实现系统网络能够标识和识别用户应用的要求。The USIM (Universal Subscriber Identity Module, Universal Subscriber Identity Module) card is the continuation and advancement of the SIM (Subscriber Identity Module, Subscriber Identity Module) card used in the UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) network. Identity information and personal data ensure the security of accessing mobile network services. Necessary functions and data can be used to perform user identification and user authorization when users access mobile network services, so that the system network can identify and identify user applications.
随着USIM业务需求的发展，为了加强USIM卡在与终端的通信时的主动性，引入了USAT(USIM Application Toolkit，USIM应用工具箱)技术。USAT技术是在原来SIM卡被动式的操作模式基础上，增加了USIM卡新的主动式操作的能力，即允许USIM卡中的应用和服务主动与手机终端进行交互操作。而USAT应用匹配是4G时代发展的新功能，可以通过USAT功能将USIM卡限制在特定的终端上使用，即仅当USIM允许使用该终端时，USIM才可以进行鉴权并正常使用，对于不被允许使用的终端，USIM不会进行鉴权。With the development of USIM service requirements, in order to strengthen the initiative of the USIM card in communicating with the terminal, the technology of USAT (USIM Application Toolkit, USIM Application Toolkit) is introduced. Based on the passive operation mode of the original SIM card, the USAT technology adds a new active operation capability of the USIM card, that is, allows the applications and services in the USIM card to actively interact with the mobile terminal. The USAT application matching is a new function developed in the 4G era. The USIM card can be restricted to 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 used normally. Terminals that are allowed to be used will not be authenticated by USIM.
在现有技术中，USAT应用匹配功能主要基于终端IMEI(International MobileEquipment Identity，国际移动设备识别码)实现，即以IMEI为判断机卡是否匹配的标准，这种功能可以支持基本的关于机卡匹配的要求，而对于其它方面的更加细节或更加复杂的机卡匹配要求则难以支持。而对于终端而言，软件应用设置也是非常关键的影响因素，部署满足要求的系统软件或应用软件，不仅意味在安全性和功能全面性方面的提升，也意味着对管理能力(包括运营商管理能力和策略)的支持。出于业务安全性、管理可实现性等方面的考虑，网络很可能要求允许机卡匹配并接入网络的终端需要具备特定软件应用情况(例如满足指定版本)，但现有技术还无法实现，因此如何实现更加细节或更加具体的机卡匹配要求是目前需要解决的问题。In the prior art, the USAT application matching function is mainly implemented based on the terminal IMEI (International Mobile Equipment Identity, International Mobile Equipment Identity), that is, the IMEI is used as the criterion for judging whether the machine card matches. This function can support basic information about machine card matching. It is difficult to support more detailed or more complex machine-card matching requirements in other aspects. For terminals, software application settings are also a very critical factor. Deploying system software or application software that meets the requirements not only means improving security and comprehensive functionality, but also improving management capabilities (including operator management). capabilities and strategies). Due to the consideration of business security and management achievability, the network may require that the terminal that allows the machine card to match and access the network needs to have specific software application conditions (for example, meet the specified version), but the existing technology is still unable to achieve, Therefore, how to achieve more detailed or more specific machine-card matching requirements is a problem that needs to be solved at present.

具体实施方式Detailed ways
为使本领域技术人员更好地理解本公开的技术方案，下面结合附图和实施例对本公开作进一步详细描述。In order to make those skilled in the art better understand the technical solutions of the present disclosure, the present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments.
其中，在本公开实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚的表示其他含义。The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. As used in the embodiments of the present disclosure and the appended claims, the singular forms "a," "the," and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise.
以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解：Hereinafter, some terms in this application will be explained so as to facilitate the understanding of those skilled in the art:
UICC(Universal Integrated Circuit Card，通用集成电路卡)，可以同时包括多种逻辑应用，SIM、USIM，及其他应用(例如电子钱包等等)。终端和USIM通过Cu接口进行数据交互。在Cu接口的协议栈中引入STK(SIMTOOL KIT，用户识别卡智能工具包)/USAT协议层，STK/USAT协议层在传输层提供的服务基础之上提供了一种服务机制，允许USIM应用与支持这种机制的终端进行交互和操作，使得USIM可以主动要求终端执行某个操作，STK/USAT指令集是电信智能卡通过终端实现业务的基础和主要方式。UICC (Universal Integrated Circuit Card, Universal Integrated Circuit Card) can simultaneously include multiple logic applications, SIM, USIM, and other applications (such as electronic wallets, etc.). The terminal and the USIM exchange data through the Cu interface. The STK (SIMTOOL KIT, user identification card smart toolkit)/USAT protocol layer is introduced into the protocol stack of the Cu interface. The STK/USAT protocol layer provides a service mechanism based on the services provided by the transport layer, allowing USIM applications to communicate with Terminals that support this mechanism interact and operate, so that USIM can actively request the terminal to perform a certain operation. The STK/USAT instruction set is the basis and main way for telecom smart cards to implement services through terminals.
借助USAT机制，USIM上可以实现更多的应用。与功能更多、人机交互更强的终端应用相比，USIM应用也具有自身优势，如更适合安全性强的业务。因此在实际应用中，越来越多的方案需使USIM应用与终端应用相结合，以便共同发挥二者优势取得更好效果。其中，USAT应用匹配是于4G时代发展的新功能，可以通过USAT功能将USIM卡限制在特定的终端上使用，USIM卡在向用户发行之前进行预置性设置，设置包括是否启用USAT应用匹配功能，如果启用，相应允许使用的终端范围。预置性设置完成之后，USIM卡在该方面的要求得以确定，USIM卡对于此后使用到USIM卡的终端，采用确定后的设置进行匹配性验证。但现有功能是基于终端IMEI实现，只能判断哪些终端可以接入，哪些终端不能接入，而无法根据终端中的软件应用设置情况进行识别，无法实现更加细节或更加具体的机卡匹配要求。With the USAT mechanism, more applications can be implemented on USIM. Compared with terminal applications with more functions and stronger human-computer interaction, USIM applications also have their own advantages, such as being more suitable for services with strong security. Therefore, in practical applications, more and more solutions need to combine the USIM application with the terminal application, so as to jointly exert the advantages of both to achieve better results. Among them, USAT application matching is a new function developed in the 4G era. The use of the USIM card can be restricted to specific terminals through the USAT function. The USIM card is preset before it is issued to users, and the settings include whether to enable the USAT application matching function. , if enabled, the corresponding range of terminals that are allowed to be used. After the preset settings are completed, the requirements of the USIM card in this aspect are determined, and the USIM card uses the determined settings to perform matching verification for the terminals that use the USIM card thereafter. However, the existing functions are implemented based on the terminal IMEI, which can only determine which terminals can be accessed and which terminals cannot be accessed, but cannot be identified according to the software application settings in the terminals, and cannot achieve more detailed or more specific machine card matching requirements. .
下面以具体地实施例对本公开的技术方案以及本公开的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。The technical solutions of the present disclosure and how the technical solutions of the present disclosure solve the above-mentioned technical problems will be described in detail below with specific examples. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.
图1为本公开实施例一提供的一种USAT应用匹配实现方法的流程示意图，应用于USIM，如图1所示，所述方法包括：FIG. 1 is a schematic flowchart of a method for implementing a USAT application matching provided in
步骤S101：当USIM接收到对USAT应用匹配的要求后，根据所述对USAT应用匹配的要求生成第一命令，其中所述对USAT应用匹配的要求包括终端满足预设条件；Step S101: after the USIM receives the requirement for matching the USAT application, it generates a first command according to the requirement for matching the USAT application, wherein the requirement for matching the USAT application includes that the terminal meets a preset condition;
步骤S102：将所述第一命令发送到终端，以使终端根据所述第一命令发送对应的终端状况到USIM；Step S102: sending the first command to the terminal, so that the terminal sends the corresponding terminal status to the USIM according to the first command;
步骤S103：接收终端发送的对应的终端状况；Step S103: receiving the corresponding terminal status sent by the terminal;
步骤S104：根据所述对USAT应用匹配的要求判断所述对应的终端状况是否满足所述预设条件，Step S104: Determine whether the corresponding terminal status satisfies the preset condition according to the requirement for matching the USAT application,
步骤S105：若不满足，则在终端进行鉴权时使鉴权失败。Step S105: If not satisfied, the authentication fails when the terminal performs authentication.
具有USAT应用匹配功能的USIM在向用户发行之前，运营商或经营商会对USIM卡进行预置性设置，设置允许使用的终端范围，预置性设置完成之后，USIM卡对于此后使用到USIM卡的终端，采用确定后的设置进行匹配性验证。但是出于业务安全性、管理可实现性等方面的考虑，网络很可能要求允许机卡匹配并接入网络的终端需要具备特定软件应用设置，以保证终端安全。Before the USIM with the USAT application matching function is issued to users, the operator or the operator will perform preset settings on the USIM card to set the range of terminals that are allowed to be used. The terminal uses the determined settings for matching verification. However, due to the consideration of service security and management achievability, the network may require that the terminal that allows the machine card to match and access the network needs to have specific software application settings to ensure terminal security.
本公开实施例在现有USAT应用匹配的基础上，提出基于应用设置的改进方案。使USIM可以预置策略，根据终端的系统软件或应用软件等应用设置情况，判断机卡的USAT应用匹配性，使达到特定要求的终端才得以使用USIM正常接入网络。Based on the existing USAT application matching, the embodiments of the present disclosure propose an improved solution based on application settings. The USIM can preset policies, and judge the USAT application compatibility of the machine card according to the system software or application software of the terminal, so that the terminal that meets the specific requirements can use the USIM to access the network normally.
进一步的，所述终端满足预设条件包括：终端的系统软件的版本满足预设要求，或者终端中安装有指定的应用软件并且所述指定的应用软件的版本满足预设要求。USAT应用匹配要求具体可以为终端的系统软件达到指定版本以上或已安装指定管理应用软件且达到指定版本以上以满足安全性要求。Further, that the terminal satisfies the preset condition includes: the version of the system software of the terminal satisfies the preset requirement, or the terminal is installed with specified application software and the version of the specified application software satisfies the preset requirement. The USAT application matching requirements may specifically be that the system software of the terminal reaches the specified version or above, or the specified management application software has been installed and reaches the specified version or above to meet the security requirements.
进一步的，所述方法还包括：Further, the method also includes:
若所述终端满足预设条件为终端中安装有指定的应用软件并且所述指定的应用软件的版本满足预设条件，则获取所述指定的应用软件的应用数据，并生成对应的第一数据对象；以及，If the terminal satisfies the preset condition that the specified application software is installed in the terminal and the version of the specified application software satisfies the preset condition, the application data of the specified application software is acquired, and corresponding first data is generated object; and,
判断是否需要提供所述指定的应用软件升级提示信息，若需要，则获取所述指定的应用软件升级提示信息的默认文本，并生成对应的第二数据对象；Judging whether it is necessary to provide the designated application software upgrade prompt information, if necessary, obtain the default text of the designated application software upgrade prompt information, and generate a corresponding second data object;
在所述第一命令中加入所述第一数据对象和第二数据对象。The first data object and the second data object are added to the first command.
USIM明确匹配依据对象应用是应用软件还是系统软件，如果是应用软件则确定匹配应用的应用数据，并生成对应的第一数据对象；如果是系统软件则不需要生成应用数据。The USIM clearly matches whether the object application is application software or system software. If it is application software, it determines the application data of the matching application, and generates a corresponding first data object; if it is system software, it does not need to generate application data.
然后USIM根据业务需要判断是否需要提供应用升级提示信息，如果需要则确定升级提示信息的默认文本，并生成对应的第二数据对象；按照业务需求生成Provide LocalInformation命令并发送到终端，可选包含上述所有的数据对象。Then the USIM judges whether it is necessary to provide the application upgrade prompt information according to the business needs, determines the default text of the upgrade prompt information if necessary, and generates the corresponding second data object; generates the Provide LocalInformation command according to the business needs and sends it to the terminal, optionally including the above All data objects.
获取到USAT应用匹配要求后，基于STK/USAT机制，在遵守机卡之间交互基本机制的前提下，首先需要扩展主动式命令，扩展USAT主动式命令Provide Local Information，即第一命令，以通过命令要求终端提供系统软件设置或指定的应用软件设置，在新增数据对象中反应软件的名称、版本等基本信息，为USIM提供USAT应用匹配判断的依据；同时改造USIM基本文件EF，在兼容原文件定义基础上，为符合要求的系统或应用软件限定范围；并设置Terminal Response命令结构，以使终端执行相应的命令之后，通过Terminal Response命令返回结果到USIM，内含USIM要求的终端具备的应用版本信息。扩展后的Provide LocalInformation命令结构可以如下表1：After obtaining the USAT application matching requirements, based on the STK/USAT mechanism, and on the premise of complying with the basic mechanism of interaction between the machine and card, it is first necessary to extend the active command and extend the USAT active command Provide Local Information, that is, the first command to pass the The command requires the terminal to provide the system software settings or the specified application software settings, and reflects the basic information such as the name and version of the software in the newly added data object, so as to provide the USIM with the basis for the matching judgment of the USAT application; Based on the definition of the file, define the scope of the system or application software that meets the requirements; and set up the Terminal Response command structure, so that after the terminal executes the corresponding command, the terminal returns the result to the USIM through the Terminal Response command, including the applications required by the USIM terminal.
