Description

一种增强型近场通信终端、 智能卡及其通信方法 技术领域
本发明涉及增强型近场通信技术， 特别是指支持一种增强型近场通信
( eNFC, enhanced Near Field Communication )终端、 智能卡及其通信方法。 背景技术
集成电路（IC, Integrate Circuit )卡、 特别是非接触式 IC卡经过十多 年的发展， 已经被广泛应用于公交、 门禁、 小额电子支付等领域。 与此同 时， 移动终端经历二十多年的迅速发展， 在居民中基本得到普及， 为人们 的工作及生活带来极大的便利； 并且， 移动终端的功能越来越强大， 存在 集成更多功能的趋势。 将移动终端与非接触式 IC卡技术结合， 使移动终端 应用于电子支付领域， 会进一步扩大移动终端的使用范围， 为人们的生活 带来更多便捷， 存在着广阔的应用前景。
在移动终端中增加对非接触式 IC卡的支持功能后， 移动终端就可以模 拟为非接触 IC卡， 与支付系统的非接触读卡器进行交互， 实现非接触支付 应用。 使用移动终端实现非接触支付的技术方案存在多种， 目前业界的主 流技术方案为 eNFC, 该技术方案得到了运营商和有关终端厂商的支持。
eNFC方案是对近场通信（NFC, Near Field Communication )方案的增 强和改进， 是工作于 13.56MHz 的一种近距离无线通信技术， 由射频识别 ( RFID , Radio Frequency Identification )技术及互连技术融合演变而来。
在移动通信终端上实现 eNFC方案需要在终端上增加 NFC模拟前端芯 片（ CLF, Contactless Front-end )和 NFC天线，并使用支持单线协议（ SWP, Single Wire Protocol ) 的智能卡， 智能卡可以是客户识别模块 （SIM , Subscriber Identity Module )卡、或用户识别模块 ( UIM, User Identity Model ) 卡、 用户服务识别模块（USIM, User Service Identity Module )卡、 或者其 它智能卡等。其中， NFC模拟前端芯片支持的通信标准包括 ISO 14443 Type A/Type B , Felica、 Mifare、 IS015693等。 移动终端中的 NFC模拟前端芯片 和 NFC天线实现非接触通信功能， 可以和外部的非接触读卡器按照有关通 信标准进行通信。
在 eNFC方案中， NFC模拟前端芯片可以通过通用异步接收 /发送装置 ( UART, Universal Asynchronous Receiver/Transmitter )接口与终端主处理 器芯片通信， 由移动终端主处理器控制 NFC模拟前端芯片的功能。 NFC模 拟前端芯片通过一根信号线与智能卡的 C6引脚连接，在物理层使用单线通 信协议（SWP, Single Wire Protocol )与智能卡通信； 在逻辑层采用主机控 制接口 （HCI, Host Control Interface ) 完成 NFC模拟前端芯片和智能卡之 间， 关于非接触卡模拟及读卡器模拟等应用的通信过程。 智能卡通过 IS07816接口和终端的主处理器芯片连接， 该连接使用到了智能卡的复位 ( Reset ) 管脚、 时钟（CLK ) 管脚、 输入输出 （10 ) 管脚， 分别对应智能 卡的 C2、 C3、 C7管脚。
eNFC的特点是， 将与电子支付有关的应用存储在智能卡中， 由智能卡 进行电子支付应用的存储和执行。 另外， 通过将智能卡的电源 （VCC ), 即 C1管脚与 NFC模拟前端芯片相连， 使 eNFC技术能够支持终端掉电模式。 在这种模式下， NFC模拟前端芯片和智能卡通过 NFC天线， 从外部的非接 触读卡器产生的电磁场获取能量， 在移动终端没电的情况下也同样能够工 作在卡模拟模式下， 与外部的非接触读卡器交互完成电子支付。
移动终端实现非接触支付时， 可以同时支持多个非接触支付应用。 智 的技术要求， 智能卡可以支持多应用， 来自不同应用提供商的支付应用可 以放在智能卡中不同的安全域， 安全域之间实现逻辑隔离， 应用之间的存 储和运行互不干扰， 从而提供安全的应用运行环境。
另外， Java卡已经成为智能卡的发展趋势， 智能卡采用 Java卡规范， 运行在智能卡中的应用可以实现平台无关性， 按照 Java卡技术规范开发的 支付应用能够运行在不同智能卡厂家的 Java卡中， 从而为支付应用的推广 带来很大的技术优势。 因此， 移动终端在支持非接触支付时， 智能卡通常 遵守 Java卡技术规范，支付应用程序采用 Java语言编写并符合 Java卡技术 规范。
对于智能卡中的应用， 每个应用拥有一个唯一的应用标识符 （AID , Application ID ), AID由注册的应用提供者标识（ RID, Registered Application Provider Identifier )和专用应用标只符扩展 ( PIX, Proprietary Application Identifier Extension )码组成， AID的编码规则符合国际标准组织 7815-5规 范:识别卡 -集成电路卡 -第五部分： 应用提供者的注册 （ISO/IEC 7816-5 Identification cards ― Integrated circuit cards ― Part 5: Registration of application providers :2004 ) 的要求。
智能卡中的支付应用可以在智能卡发行时预置在智能卡中； 也可以在 智能卡发行后， 通过移动终端从远程服务器将支付应用下载到智能卡中。 应用在智能卡上进行安装时， 会将应用的有关信息注册到智能卡中的注册 表（Registry )中， 注册的信息可以包括应用的名称、 AID和应用的状态等。
移动终端模拟为非接触卡进行支付时， 移动终端和非接触支付系统的 非接触读卡器之间采用无线通信技术进行通信， 一般采用射频识别技术， 国外有些国家也采用其他的近距离通信技术。 目前， 现有的非接触支付系 统中非接触卡或者用作非接触卡的终端设备， 与非接触支付系统的读卡器 之间的通信， 并没有采用一个相同的通信标准， 而是非接触支付系统根据 系统自己的需求采用相应的通信标准， 非接触卡和读卡器之间按照采用的 通信标准中规定的射频接口和通信协议进行通信， 应用在非接触支付的通 信标准主要为射频识别技术的有关标准， 包括 IS014443 Type A、 IS014443 TypeB , Mifare、 Felica和 IS015693等， 国外的一些国家采用了其他的近距 离通信技术。 例如： 公共交通卡支付系统一般采用 IS014443 Type A标准和 Mifare标准， 非接触银行卡支付系统一般采用 IS014443 Type B标准。
移动终端采用 eNFC方案和 NFC方案实现非接触支付的目标是能够支 持多种非接触支付应用， 可以支持多种通信标准， 能够按照相应的通信标 准的技术要求和不同的非接触支付系统的读卡器进行通信。 为了使移动终 端可以支持多种通信标准， 移动终端中的 NFC模拟前端芯片应能够支持多 种通信标准， 并且智能卡能够支持多种通信标准。
电子支付应用程序 Applet基于 javacard.framework. Applet类库，可实现
" Java 卡平台运行环境规范 V2.2.2 版本" ( " Runtime Environment Specification for the Java Card Platform, Version 2.2.2" ) 中定义的安装
( install )、注册 ( register )、选择 ( select )、去选择 ( deselect )、进程 ( process ), 先使用 Java编译器将源代码文件编译为二进制的类文件（ .class文件 ), 再 使用转换器和校验器将类文件进行转换， 转换后的文件为可以安装到智能 卡上的安装文件， 即 CAP ( Converted Applet )文件。 支付应用的安装文件 下载到智能卡后， 可以执行支付应用的安装； 支付应用完成安装及个人化 后， 即可启用所安装的支付应用进行相应的支付业务。
在 eNFC方案中， NFC模拟前端芯片和智能卡之间在逻辑层采用 HCI 接口进行通信， 完成移动终端模拟为非接触 IC卡时的通信过程。 在欧洲电 信标准协会 102 622规范： "智能卡 -通用集成电路卡与近场通信模拟前端芯 片接口 -主机控制接口 " （ ETSI TS 102 622 "Smart Cards; UlCC-Contactless Front-end ( CLF ) Interface ;Host Controller Interface ( HCI )" ) 中对 HCI接 口进行了规定。 根据 HCI接口的要求， 在将移动终端模拟为非接触卡时， NFC 模拟前端芯片作为主机控制器 （Host Controller ), 智能卡作为主机 ( Host ), NFC模拟前端芯片处理和外部的非接触读卡器的通信， 智能卡负 责非接触支付应用的处理。
其中， NFC模拟前端芯片至少可以支持一种通信标准， 对于其所支持 的每一种通信标准， NFC模拟前端芯片中存在一个对应的非接触卡射频入 口 （ Card RF Gate ); 智能卡可以至少支持一种通信标准， 对于其所支持的 每一种通信标准， 智能卡中存在一个对应的非接触卡应用入口 （Card Application Gate )。 智能卡中的 Card Application Gate可以和 NFC模拟前端 芯片中对应的 Card RF Gate建立管道（ Pipe ) , 通过管道传递所对应的通信 标准的数据传输。 在智能卡和 NFC芯片之间同时支持多种通信标准时， 每 个通信标准都拥有 NFC模拟前端芯片和智能卡之间的一个专门的管道， 智 能卡负责与 NFC模拟前端芯片之间的管道的建立和关闭。
在移动终端处于非接触卡模拟模式时， 在 NFC模拟前端芯片给智能卡 上电后， 智能卡和 NFC模拟前端芯片之间采用单线协议， 建立物理层和数 据层的通信； 之后智能卡获取 NFC模拟前端芯片中存在的 Card RF Gate, 然后建立智能卡中的 Card Application Gate和 NFC模拟前端芯片中的对应 的 Card RF Gate之间的管道。 在 NFC模拟前端芯片中的 Card RF Gate和智 能卡中对应的 Application Gate建立管道后， NFC模拟前端芯片才会启动 NFC模拟前端芯片中和该 Card RF Gate对应的通信标准的有关功能， 在移 动终端进入到采用该通信标准的非接触读卡器的工作区域后， NFC模拟前 端芯片会响应非接触读卡器发送的有关信号。
在目前的技术情况下， 非接触支付应用不能标识该非接触支付应用对 应的非接触支付系统所采用的通信标准； 在非接触支付应用被安装到智能 卡后， 智能卡也无法获知卡上已经安装的非接触支付应用所对应的通信标 准。 因此， 智能卡上电后， 智能卡中存在的 Card Application Gate都将与 NFC模拟前端芯片中对应的 Card RF Gate建立管道； 建立管道后， NFC模 拟前端芯片的通信功能都会开启并响应相对应的非接触读卡器的信号。 但 是， 这种处理方法会产生的一个问题是： 即使智能卡中不存在采用某个通 信标准的非接触支付应用， 智能卡仍然会与 NFC模拟前端芯片建立与这个 通信标准对应的管道， 从而开启 NFC模拟前端芯片与这个通信标准对应的 有关功能； 如此， 移动终端进入到采用该通信标准的非接触读卡器的工作 区域内时， 会响应该非接触读卡器发送的信号并与非接触读卡器建立通信， 而智能卡内不存在与该通信标准对应的非接触支付应用， 移动终端是没有 必要与该非接触读卡器建立通信的。 发明内容

本发明还提供了一种 eNFC终端， 包括具有若干个卡射频入口的 NFC 模拟前端芯片和具有若干个卡应用入口的智能卡， 该智能卡具有上面描述 的记录单元、 判断单元和管道创建单元。
本发明还提供了智能卡与 NFC模拟前端芯片通信的方法， 包括： 首先， 在非接触支付应用中提供标志信息来标识支付应用对应的非接 触支付系统所采用的通信标准。
具体而言， 该步骤可以这样实现： 在非接触支付应用程序发布过程中， 使用转换器将类文件转换为可以安装到智能卡上的安装文件，如 CAP文件； 在转化命令中的版本参数中加入非接触支付应用所对应的通信标准的标识 信息， 通过非接触支付应用程序的版本号中的标识信息， 来标识对应的非 接触支付系统所采用的通信标准。
然后， 在非接触支付应用的安装过程中， 在智能卡记录该支付应用的 信息时， 记录该非接触支付应用对应的非接触支付系统所采用的通信标准。
在智能卡的注册表中记录支付应用的信息， 包括： 该非接触支付应用 对应的非接触支付系统所采用的通信标准的标识信息。
接下来， 在智能卡内部执行下面的步骤：
智能卡创建自身中 Card Application Gate和 NFC模拟前端芯片中 Card RF Gate之间的管道时，先对于智能卡中的每个 Card Application Gate,通过 查询智能卡中的注册表来判断是否存在与 Card Application Gate对应的非接 触支付应用， 注册表中记录有已安装的非接触支付应用所对应的通信标准 的标识信息。 这里， 与 Card Application Gate对应的非接触支付应用指安装 在智能卡中的某个或者某些非接触支付应用， 其对应的非接触支付系统所 采用的通信标准与 Card Application Gate对应的通信标准相同。 智能卡在注 册表中进行查询时， 判断在已安装的非接触支付应用中是否有非接触支付 应用所对应的通信标准与 Card Application Gate所对应的通信标准相同。
如果智能卡中存在与 Card Application Gate对应的非接触支付应用， 则 智能卡创建该 Card Application Gate和 NFC模拟前端芯片中对应的 Card RF Gate之间的管道， NFC模拟前端芯片启用被创建的管道所对应的通信标准 的有关功能； 如果智能卡中不存在与 Card Application Gate对应的非接触支 付应用， 则智能卡不创建该 Card Application Gate和 NFC模拟前端芯片中 对应的 Card RF Gate之间的管道， NFC模拟前端芯片也不会启用和该 Card Application Gate对应的通信标准的有关功能。
在 eNFC方案中， 由智能卡保存非接触支付应用， 智能卡提供安全、 开 放的应用运行环境。智能卡可以根据使用情况的不同，可以是 SIM卡、 UIM 卡、 USIM卡或者其它智能卡。
在下面介绍本发明的一个具体实施方式时， 将以 USIM卡为例； 同样， 在智能卡是 SIM卡、 UIM卡或者其它智能卡时，也可以采用本发明的方法。
USIM 卡可以采用 Java 卡技术， 并遵守 Global Platform Card Specification V2.2; USIM 卡中存在 Java卡运行环境（JCRE, Java Card Runtime Environment )。 JCRE包括 Java卡虚拟机 ( JCVM, Java Card Virtual Machine ), Java卡才 架及 API接口 （ Java Card Framework and API )和卡提 供商指定的扩展接口。
非接触电子支付应用的程序 Applet基于 javacard.framework. Applet类
Version 2.2.2 " 中定义的 install, register, select, deselect, process方法, 以及按照对应的非接触支付应用规范实现支付业务的处理。 每个应用拥有 一个唯一的 AID, AID由注册的应用 RID和 PIX组成， AID的编码规则可 、参月 ISO/IEC 7816-5 Identification cards ― Integrated circuit cards —Part 5 egistration of application providers :2004的要求。
非接触支付应用程序发布时， 需要先使用 Java编译器将源代码文件编 译为二进制的类文件 （.class 文件）； 再使用转换器和校验器将类文件进行 转换， 转换后的文件为可以安装到 SIM卡上的安装文件， 即 CAP文件。
转换器 ( converter )是由 Java卡开发工具包 ( Java Card Development kit ) 提供的字节代码工具，作为字节代码工具， 它需要 Java解释器的帮助才能 运行。 它将 class 文件转换成一些输出文件， 转换时， 输入文件是： 由编 译器生成的 class 文件； 输出文件是： Cap 文件， Export文件， JCA文件， 它们的后缀分别是： *.cap,*.exp,*.jca, 文件名与输入文件一致。 它们将位于 Java卡项目目录下的一个叫 Javacard 的子目录中。
转换器命令行的格式为： <解释器 > <-classpath> <被执行的 class> <可 选参数 > <包 ( package )名> <包 AID> <版本 > 。
其中， 解释器用于提供解释器的路径和文件名， 如 c:\JDK\bin\java.exe; 被执行的 class就是位于 converter.jar中 com\sun\javacard\converter\ converter\ 目录下的一些类。
在安装 Java卡开发工具（ Java Card Development kit )后， 开发工具会 提供一个批处理文件 converter.bat, 该批处理文件包含的就是命令行中： < 解释器 > <-classpath> <被执行的 class> 这三部分内容。 也就是说， 在进行 Applet转换时， 对这三部分参数可以不十分了解， 而直接使用 converter.bat 进行文件转换。
可选参数为命令行中的一些可选参数， 包括有：
-classdir: 项目的才艮目录；
-exportpath： 一些转换时要用到的 Exp 文件的父目录； -d: 输出的路径， 它指明的是根目录；
-applet [AID][classname]:指明缺省 Applet 的 AID,和含 Install ( ) 方 法的 class 文件名。
-out [CAP] [EXP] [JC A]: 说明要转换器生成什么文件， 一般默认为生成 CAP和 EXP文件；
-nobanner: 信息使用标准输出。
包名是指要被转换的包名； 包 AID为指定 Applet 的 AID; 版本为定 义 Applet的版本号。
举个例子来说， 转换器命令行的一个示例可以是： c:\JDK\bin\java.exe -classpath c:\jc211\bin\converter.jar com.sun.javacard.converter.Converter -out EXP JCA CAP -exportpath c:\jc211\api21 -applet OxaO :0x0:0x0:0x0:0x62:0x3:0x1 :0xc:0xl :0x1
com.sun.javacard.samples.HelloWorld.HelloWorld
com. sun.j avacard. samples .Hello World OxaO :0x0: 0x0： 0x0 :0x62:0x3:0x1 : Oxc： Ox 1 Vl.O o
USIM卡支持多应用， 可以在卡上安装多个应用。 支付应用可以预先安 装到 USIM卡， 也可以在 USIM卡发行后通过移动通信网络从远程服务器 上下载并安装到 USIM卡。非接触支付应用的 CAP文件下载到 USIM卡后， USIM可以获取到非接触支付应用的 AID和版本号等信息； 应用在 USIM 卡上进行安装时， 会将非接触支付应用的有关信息注册到 USIM卡中的注 册表中， 注册的信息可以包括应用的名称、 AID和应用的状态等。
为了使非接触支付应用可以标识对应的非接触支付系统所采用的通信 标准， 使用转换器将非接触支付应用程序的类文件转换为可以安装到智能 卡上的安装文件时， 在转化命令的版本参数中加入非接触支付应用所支持 的通信标准的标识信息， 通过非接触支付应用程序的版本号中的标识信息 来标识对应的非接触支付系统所采用的通信标准。 一般， 版本号的格式可以为： AP_ "通信标准的标识符" _ "版本号"， 通信标准的标识符可以采用字母来表示， 比如： 采用 A表示 IS014443 Type A标准， 采用 B表示 IS014443 Type B标准， 采用 C表示 Felica标准， 采 用 M表示 Mifare标准， 采用 F表示 ISO 18092标准。 举例来说， 版本号为 "AP_B_1.0" ,就表示非接触支付应用对应的非接触支付系统所采用的通信 标准为 IS014443 Type B标准， 版本为 1.0。 当然， 根据需要也可以采用其 它的版本号编码格式。
非接触支付应用的程序在被转化为可以安装到 USIM卡上的 CAP文件 后，就可以将该 CAP文件通过移动通信网络从远程服务器上下载到智能卡。 为了实现支付应用程序的远程下载， 移动终端需要支持数据业务， 并支持 采用数据业务的方式实现空中下载 （OTA, On The Air ); 为使数据高速下 载到 USIM卡，移动终端和 USIM卡之间可采用承载无关协议（ BIP, Bearer Independent Protocol )进行通信。
BIP协议是第三代移动通讯伙伴计划（ 3GPP, 3rd Generation Partnership Project )规范中提出的一种面向连接的传输协议， 可支持的高速通道包括： 通用分组无线业务（GPRS )、 增强型数据速率 GSM 演进技术（EDGE, Enhanced Data Rate for GSM Evolution )以及 UMTS等；支持五个主动命令， 具体为： OPEN CHANNEL (打开信道）、 CLOSE CHANNEL (关闭信道）、 RECEIVE DATA (接收数据 )、 SEND DATA (发送数据 )、 GET CHANNEL STATUS (获取信道状态）； 还支持两种事件， 具体为： Data available (数据 可用）和 Channel status (信道状态）， 使 USIM卡能利用移动终端的承载能 力建立与远端 OTA服务器之间的面向连接的数据通道。
智能卡可通过 BIP的 OPEN CHANNEL命令指示移动终端通过移动数 据业务通道连接到远程的 OTA服务器， 通过卡应用工具包 （CAT, Card Application Toolkit )的方式， 浏览 OTA服务器上可下载的非接触支付应用； 在移动终端侧确定下载应用后， 将向远程的 OTA服务器发起应用下载请求 消息， OTA服务器收到应用下载请求后将选择 USIM卡上的安全域， 该安 全域用于存储下载的非接触支付应用； 选择 USIM卡上的安全域后， OTA 服务器将和 USIM中的安全域按照 Global Platform Card Specification V2.2 中对安全信道（Secure Channel ) 的规定建立安全信道； 安全信道建立完成 后， 远程的 OTA服务器向 USIM卡发送 INSTALL[for load]命令， 智能卡与 OTA服务器之间开始非接触支付应用的下载。
在支付应用下载完成后， 远程的 OTA服务器可以发送 INSTALL[for install]命令给 USIM卡， 指示 USIM卡安装下载的支付应用。
本实施例中， 在非接触支付应用安装的过程中， 执行非接触支付应用 的注册时， USIM卡可以将非接触支付应用对应的非接触支付系统所采用的 通信标准信息添加到 USIM卡的注册表中， 通过注册表记录非接触支付应 用所对应的通信标准。 为实现可以在 USIM卡的注册表中记录非接触支付 应用所对应的通信标准， USIM卡的注册表可以在记录已安装的非接触支付 应用的信息中设置一个标识信息， 该标识信息用于记录非接触支付应用所 对应的通信标准。 通信标准的标识信息可以采用非接触支付应用中通信标 准标识符的编码规则， 如： 采用 A表示 IS014443 Type A标准， 采用 B表 示 IS014443 Type B标准， 采用 C表示 Felica标准， 采用 M表示 Mifare标 准， 采用 F表示 ISO18092标准。
具体地， USIM安装非接触支付应用时， USIM卡会调用非接触支付应 用程序的 install方法。在 install方法中，创建非接触支付应用的实例和所需 要的对象， 并进行初始化操作， 为数据赋初值； 最后调用非接触支付应用 的 register方法将非接触支付应用注册到 USIM卡中的注册表中； 在执行注 册时， 将非接触支付应用的信息添加到 USIM卡的注册表， 信息可以包括 非接触支付应用的名称、 AID 和非接触支付应用所对应的通信标准的标识 信息。 register方法成功运行后， 非接触支付应用安装成功， USIM卡可以 在发送给远程 OTA服务器的 INSTALL[for install]响应消息中报告安装成 功。
下面结合图 1说明本实施例中 USIM卡在上电后创建管道的处理过程， 包括以下步骤：
步骤 101 , NFC模拟前端芯片给智能卡上电后， USIM卡与 NFC模拟 前端芯片之间采用单线协议建立物理层和数据层的通信。
步骤 102, USIM卡获取 NFC模拟前端芯片所支持的 Card RF Gate列 表；
这里， USIM卡和 NFC模拟前端芯片之间按照主机控制接口的要求进 行逻辑层的通信。 具体的： USIM卡中的管理入口 （ Administration Gate ) 通过管道 PIPE1向 NFC模拟前端芯片的 Administration Gate发送获取参数 命令 ANY_GET_PARAMETERS ( GATES_LIST ); NFC模拟前端芯片的管 理入口返回 NFC模拟前端芯片支持的入口 （Gate ) 歹l表， 其中包括其所支 持的 Card RF Gate。
步骤 103 , USIM卡为 USIM中的每个 Card Application Gate与 NFC模 拟前端芯片中对应的 Card RF Gate建立管道前， USIM卡会判断自身中的 Card Application Gate是否有对应的非接触支付应用， 如果 USIM卡中存在 与 Card Application Gate对应的非接触支付应用， 则执行步骤 104; 如果 USIM卡中不存在与 Card Application Gate对应的非接触支付应用， 则执行 步骤 105。
这里， 与 Card Application Gate对应的非接触支付应用是指安装在智能 卡中的某个或者某些非接触支付应用， 其对应的非接触支付系统所采用的 通信标准与卡应用入口对应的通信标准相同。例如用于 IS014443 Type A的 Card Application Gate对应的非接触支付应用为同样采用 IS014443 Type A 标准的非接触支付应用。
在本实施例中， 判断的方法为 USIM卡在其注册表中检索非接触支付 应用在安装时注册的对应的通信标准的标识信息， 根据该标识信息判断是 否存在与 Card Application Gate对应的非接触支付应用。
步骤 104, USIM卡创建该 Card Application Gate与 NFC模拟前端芯片 中对应的 Card RF Gate之间的管道， NFC模拟前端芯片开启对应的通信标 准的有关功能；
具体的， USIM 卡可以在 ADM_CREATE_PIPE命令中指定要连接的 NFC芯片中的 Card RF Gate的 ID号， 并将该命令通过 PIPEl管道发送给 NFC 模拟前端芯片的 Administration Gate , NFC 模拟前端芯片的 Administration Gate 接收到命令后指定要创建的管道的 ID 号， 并返回 ANY_OK,从而建立 USIM卡中的 Card Application Gate和与其对应的 NFC 芯片中 Card RF Gate之间的管道； 管道创建完成后， NFC模拟前端芯片开 启对应的通信标准的有关功能， 使移动终端可以与对应的非接触读卡器进 行通信， 并完成有关非接触支付。
步骤 105 , USIM卡不创建该 Card Application Gate与 NFC模拟前端芯 片中对应的 Card RF Gate之间的管道， NFC模拟前端芯片也不开启对应的 通信标准的有关功能。
上面描述了 USIM卡为 USIM卡中的一个 CardApplication Gate创建管 道的处理过程， 如果 USIM卡中存在多个 Card Application Gate, USIM卡 可以采用同样的方法依次为存在的每个 Card Application Gate创建对应的管 道。
