Description

一种SE的自动路由方法及电子设备
本申请要求在2019年04月26日提交国家知识产权局、申请号为201910345528.5、发明名称为“一种SE的自动路由方法及电子设备”的中国专利申请的优先权，在2019年05月21日提交国家知识产权局、申请号为201910426179.X、发明名称为“一种SE的自动路由方法及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及近距离无线通信(Near Field Communication，NFC)技术领域，尤其涉及一种安全单元(Security Element，SE)的自动路由方法及电子设备。
背景技术
NFC是一种近距离无线通信技术，允许设备之间进行非接触式点对点数据传输。NFC具有较高的安全性，近年来越来越被大众欢迎和接受。其中，具备NFC功能的电子设备的发展尤为迅速。具备NFC功能电子设备可以工作于三种模式：读卡器模式，卡模拟模式，点对点模式。其中，卡模拟模式的使用频率最高。电子设备可模拟为一张非接触集成电路(Integrated Circuit，IC)卡，用户手持电子设备便可与读卡器进行交互，以完成刷银行卡、刷公交卡或刷社保卡等操作，给生活带来很多便利。
电子设备在模拟为非接触IC卡与读卡器进行交互之前，需下载对应的NFC应用到电子设备的安全单元(Security Element，SE)中。SE可以为NFC应用的运行提供安全的执行环境，为其敏感数据提供安全的存储环境。
目前，一个电子设备可能有多个SE。通常来说，移动运营商倾向于使用以用户标识模块(subscriber identification module，SIM)卡形式存在的SE、电子设备制造商倾向于使用eSE、应用生产商倾向于使用主机卡模拟(host card emulation，HCE)。通常，电子设备的NFC控制器可以通过将路由指向某个SE的方法，来决定当前的NFC交易由哪个SE承接。
一个SE中可同时承载多个NFC应用。在SE中承载的NFC应用被激活时，电子设备便可模拟为对应的非接触IC卡与读卡器进行交互。其中，NFC应用可由用户手动激活，也可由电子设备自动激活。具体的，电子设备在接收到读卡器发送的交易指令后，可以根据交易指令中携带的应用标识符(Application Identifier，AID)来判别该交易指令访问的是SE中承载的哪个NFC应用。
通常，只有NFC控制器的路由所指向的SE可以承接NFC交易，即处理交易指令。而当交易指令要访问承载在其他SE中的NFC应用时，交易则无法进行。该其他SE不是NFC控制器的路由所指向的SE。因此，当电子设备有多个SE时，如何让NFC控制器的路由指向交易指令所要访问的NFC应用所在的SE，是亟待解决的问题。
发明内容
本申请实施例提供一种SE的自动路由方法及电子设备，即使电子设备中包括多个SE，也可以自动路由到交易指令访问的NFC应用所在的SE。
第一方面，本申请实施例提供一种电子设备，该电子设备包括NFC控制器和至少两 个SE。该至少两个SE中的每个SE中承载了至少一个NFC应用。该NFC控制器中保存了多个NFC应用的第一标识和SE位置信息。该SE位置信息指示承载对应NFC应用的SE。NFC控制器可接收交易指令；响应于交易指令中携带第一标识，NFC控制器可从NFC控制保存的SE位置信息中，查找交易指令携带的第一标识对应的SE位置信息；NFC控制器根据查找到的SE位置信息,从至少两个SE中确定第一目标SE，向第一目标SE发送所述交易指令。
本申请实施例中，由于NFC控制器可保存多个NFC应用的第一标识和SE位置信息；因此电子设备接收到携带第一标识的交易指令后，则可以根据交易指令携带的第一标识，确定交易指令所要访问的NFC应用的SE位置信息。即电子设备可以确定交易指令所要访问的NFC应用承载在哪一个SE中。
本申请实施例中，NFC控制器可以根据交易指令中携带的第一标识，自动路由至交易指令所要访问的NFC应用所在的SE。
结合第一方面，在一种可能的设计方式中，第一目标SE可以接收交易指令，根据交易指令携带的第一标识，从第一目标SE承载的NFC应用中确定第一目标NFC应用；第一目标SE运行第一目标NFC应用，执行交易指令。
也就是说，目标SE可以根据交易交易指令携带的第一标识，向交易指令所访问的NFC应用发送该交易指令，由交易指令所访问的NFC应用执行该交易指令，以便完成交易。
结合第一方面，在另一种可能的设计方式中，上述第一标识是AID。当然，第一标识包括但不限于AID。
结合第一方面，在另一种可能的设计方式中，第一目标NFC应用的NFC管理应用携带第一目标NFC应用的第一标识和第一目标NFC应用的SE位置信息。该第一目标NFC应用的SE位置信息指示承载第一目标NFC应用的第一目标SE。其中，NFC管理应用用于管理一个或多个NFC应用。NFC控制器，用于接收第一目标NFC应用的NFC管理应用向电子设备的默认付款应用注册时，传输的第一目标NFC应用的第一标识和第一目标NFC应用的SE位置信息。
其中，第一目标NFC应用的NFC管理应用安装时，向电子设备的默认付款应用注册；NFC控制器，还用于保存第一目标NFC应用的第一标识和第一目标NFC应用的SE位置信息。
结合第一方面，在另一种可能的设计方式中，上述向第一目标SE发送交易指令，可以包括：如果第一目标SE是NFC控制器的路由所指向的SE，NFC控制器可以直接将接收到交易指令传输至该第一目标SE，由第一目标SE向交易指令所访问的NFC应用发送交易指令，由交易指令所访问的NFC应用执行该交易指令完成交易。如果该第一目标SE不是NFC控制器的路由所指向的SE，NFC控制器可以修改路由指向该第一目标SE，然后将接收到交易指令传输至该SE，由该SE向交易指令所访问的NFC应用发送交易指令所访问的NFC应用，由交易指令所访问的NFC应用执行该交易指令完成交易。
可以理解，上述SE位置信息所指示的SE可能是NFC控制器的路由所指向的SE，也可能不是NFC控制器的路由所指向的SE。电子设备查找到上述第一标识对应的SE位置信息后，可以判断该SE位置信息所指示的SE是为NFC控制器的路由所指向的SE。如果该SE位置信息所指示的SE是NFC控制器的路由所指向的SE，NFC控制器可以直接将接收到交易指令传输至该SE，由该SE向交易指令所访问的NFC应用发送交易指令，由交 易指令所访问的NFC应用执行该交易指令完成交易。如果该SE位置信息所指示的SE不是NFC控制器的路由所指向的SE，NFC控制器可以修改路由指向该SE，然后将接收到交易指令传输至该SE，由该SE向交易指令所访问的NFC应用发送交易指令，由交易指令所访问的NFC应用执行该交易指令完成交易。
结合第一方面，在另一种可能的设计方式中，由于不是所有的NFC应用都支持并使用第一标识(如AID)。以第一标识是AID为例。例如，一些公交卡不支持并使用AID。因此，电子设备的NFC控制器接收到的交易指令中是不包括第一标识的。基于这种情况，电子设备的处理器中可以保存一个或多个非标准NFC应用的使用场景信息、SE位置信息和第二标识。
例如，电子设备(例如，电子设备的处理器)可以维护一个非标卡信息表。该非标卡信息表中可以包括电子设备中安装的非标准NFC应用的查询信息。非标准NFC应用的查询信息可以包括非标准NFC应用的使用场景信息、SE位置信息和第二标识。
其中，非标准NFC应用不支持AID。第二标识用于标识非标准NFC应用，第二标识不是第一标识(如AID)。使用场景信息用于指示使用对应非标准NFC应用的场景信息。
具体的，处理器响应于NFC控制器接收的交易指令中未携带第一标识，可以获取电子设备的当前场景信息；处理器从一个或多个非标准NFC应用的使用场景信息中查找当前场景信息对应的使用场景信息，并确定查找到的使用场景信息对应的第二标识和SE位置信息；处理器根据查找到的SE位置信息，从至少两个SE中确定第二目标SE,向第二目标SE发送交易指令；第二目标SE接收交易指令；处理器向第二目标SE指示查找到的第二标识；第二目标SE根据处理器指示的第二标识，从第二目标SE承载的NFC应用中确定第二目标NFC应用，第二目标NFC应用是非标准NFC应用；第二目标SE运行第二目标NFC应用，执行交易指令。
本申请实施例中，即使一些NFC应用不支持AID，电子设备也可以在接收到交易指令后，根据电子设备的当前场景信息，确定交易指令所要访问的非标准NFC应用所在的SE。即可以实现交易指令所访问的非标准NFC应用所在SE的自动路由。
并且，还可以根据电子设备的当前场景信息，确定交易指令所要访问的非标准NFC应用。如此，SE便可以向交易指令所要访问的非标准NFC应用发送交易指令。
结合第一方面，在另一种可能的设计方式中，上述NFC控制器可保存路由表，该路由表中包括多个NFC应用的第一标识和SE位置信息。该路由表还可以包括非标卡缺省项，非标卡缺省项用于在交易指令未携带第一标识的情况下，指向电子设备的当前场景信息对应的SE。其中，处理器可根据查找到的SE位置信息，从至少两个SE中确定第二目标SE，向NFC控制器指示第二目标SE。NFC控制器响应于处理器的指示，可配置非标卡缺省项指向第二目标SE。NFC控制器可向非标卡缺省项指向的第二目标SE发送交易指令。
结合第一方面，在另一种可能的设计方式中，上述与当前的场景信息对应的SE位置信息所指示的第二目标SE可能是NFC控制器的路由所指向的SE，也可能不是NFC控制器的路由所指向的SE。电子设备查找到上述SE位置信息后，可以判断该SE位置信息所指示的SE是否为路由表中的非标卡缺省项所指向的SE。如果该SE位置信息所指示的SE是非标卡缺省项所指向的SE，NFC控制器可以直接将接收到交易指令传输至该SE，由该SE自动激活与当前的场景信息对应的标识所指示的非标准NFC应用，执行该交易指令完成交易。如果该SE位置信息所指示的SE不是非标卡缺省项所指向的SE，NFC控制器则可以配置路由表中的非标卡缺省项指向该SE，然后将接收到交易指令传输至该SE，由该 SE自动激活与当前的场景信息对应的标识所指示的非标准NFC应用，执行该交易指令完成交易。
结合第一方面，在另一种可能的设计方式中，上述场景信息至少包括地理位置信息、时间信息和操作信息中的一项或多项；地理位置信息用于指示对应非标准NFC应用可被使用的地理位置；时间信息用于指示对应非标准NFC应用可被使用的时间；操作信息用于指示对应非标准NFC应用被使用前用户对电子设备的操作。
结合第一方面，在另一种可能的设计方式中，上述至少两个SE中的第一SE中承载有第一NFC应用和第二NFC应用；其中，第一NFC应用支持的NFC业务的验证方式为直接刷卡模式，不需要进行用户验证。例如，第一NFC应用可以是“公交卡”应用。第二NFC应用支持的NFC业务的验证方式为要求验证模式，需要进行用户验证。例如，第二NFC应用可以是“银行卡”应用。其中，“银行卡”应用对应要求验证模式，需要通过用户验证(如密码验证、指纹验证、人脸验证、虹膜认证、声纹认证、行为认证等)，才可以完成交易。而“公交卡”应用则对应直接刷卡模式，不需要用户验证便可以完成交易。
其中，电子设备的处理器响应于用户的设置操作，激活第一NFC应用，以设置第一NFC应用为电子设备中默认的NFC应用；处理器响应于用户的预设快捷操作，去激活第一NFC应用，自动激活第二NFC应用，以设置第二NFC应用为电子设备中默认的NFC应用。
上述方案可以理解为本申请实施例提出“直刷为常态，验证为临时”的概念。在该电子设备中，上述第一NFC应用可以为常态下默认的NFC应用，上述第二NFC应用可以为临时默认的NFC应用。
具体的，一般情况下，电子设备中默认的NFC应用可以为上述第一NFC应用(该第一NFC应用可以由用户设置为默认的NFC应用)；如此，用户随时使用该电子设备都可以与第一NFC应用对应的读卡器或POS机具完成交易。而当用户想要使用上述第二NFC应用付款时，则可以在电子设备输入预设快捷操作。响应于该预设快捷操作，电子设备可以临时将上述第二NFC应用设置为默认的NFC应用，以使电子设备可以与第二NFC应用对应的读卡器或POS机具完成交易。
本申请实施例中，即使一个NFC管理应用中管理了直接刷卡模式的第一NFC应用(如“公交卡”应用、“社保卡”应用，或者“车钥匙”应用等)和要求验证模式的第二NFC应用(如“银行卡”应用)，也不需要用户在该NFC管理应用中频繁设置默认的NFC应用。电子设备可以随时与第一NFC应用对应的读卡器或POS机具完成交易；并且，可以响应于预设快捷操作，与第二NFC应用对应的读卡器或POS机具完成交易。
第二方面，本申请实施例提供一种电子设备，该电子设备包括处理器和至少两个安全单元SE，至少两个SE中的第一SE中承载了第一NFC应用和第二NFC应用，第一NFC应用支持的NFC业务的验证方式为直接刷卡模式，不需要进行用户验证；第二NFC应用支持的NFC业务的验证方式为要求验证模式，需要进行用户验证；用户验证至少为密码验证、指纹验证、人脸验证、虹膜认证、声纹认证、行为认证等中的任一项。处理器响应于用户的设置操作，激活第一NFC应用，以设置第一NFC应用为电子设备中默认的NFC应用；处理器响应于用户的预设快捷操作，去激活第一NFC应用，自动激活第二NFC应用，以设置第二NFC应用为电子设备中默认的NFC应用。

具体实施方式
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
请参考图1A，其示出本申请实施例提供的一种NFC通信系统示意图。如图1A所示，该NFC通信系统可以包括电子设备100和外界读卡器101。
其中，电子设备100和外界读卡器101中均包括NFC芯片，可以通过NFC通信。示 例性的，外界读卡器101可以为图2所示的银行POS机、公交POS机或车门读卡器等。或者，外界读卡器101还可以是社保卡读卡机等。本申请实施例对外界读卡器101的具体形态不作限定。
为了便于理解，示例的给出了部分与本申请实施例相关概念的说明以供参考。如下所示：
NFC应用：是用于实现近距离通信的应用程序，其具备用于模拟非接触IC卡的仿真功能。根据应用场景的不同，NFC应用可以分为不同的类型。如，公交类应用、门禁类应用、银行卡类应用等。
其中，NFC应用具有AID，但并不是所有的NFC应用都支持并使用AID。使用AID的NFC应用支持AID识别，即电子设备100能够根据交易指令中携带的AID识别出交易指令所访问的NFC应用。
电子设备100实现卡模拟需要包括三个功能实体，分别为：设备主机(device host，DH)，NFC控制器(NFC controller，NFCC)和SE。其中：
DH：可以负责NFCC的管理，如初始化、配置和电源管理等。
NFCC：可以负责通过天线进行数据的物理传输。其中，DH可以包含在电子设备100的主芯片中，NFCC可以包含在电子设备100的NFC芯片中。
SE：可以负责为NFC应用提供安全执行环境(如认证、授权等)以及敏感数据存储的环境。SE是一个安全单元芯片。SE中可同时承载多个NFC应用。
其中，电子设备100可以有一个或多个SE。如果电子设备100有多个SE，则这些SE可以以不同的形式存在。
例如，如图1B所示，电子设备100可以有三个SE。这三个SE分别可以为：以用户标识模块(subscriber identification module，SIM)卡形式存在的SE 1，与NFC芯片一起封装的SE 2，以及以电子设备100的主芯片(如图1B中所示的应用处理器(application processor，AP))形式存在的eSE。对于eSE而言，SE的硬件(如图1B所示的SE 3)部署在位于云端的服务器中。其中，SE 3称为主机卡模拟(host card emulation，HCE)。
当然，上述SE只是作为示例，在本实施例中，SE还可以以其他形式存在于电子设备100。如，以SD卡形式存在的SE。又如，以通用集成电路卡(Universal Integrated Circuit Card，UICC)形式存在的SE等等，本实施例对此不作限制。
NFC应用下载到对应的SE之后，NFC应用可以在“默认付款应用”中注册(即执行图2所示的S1)。这样，用户使用某项NFC应用时，才可以在电子设备的默认付款应用的选择界面中设置默认的NFC应用。
具体的，用户可以通过如下操作控制电子设备100显示默认付款应用的选择界面：用户点击“设置”应用的应用图标，电子设备100显示设置界面；用户点击设置界面中的“NFC”选项，电子设备100显示NFC设置界面；用户点击NFC设置界面中的“默认付款应用”选项，电子设备100显示默认付款应用的选择界面。其中，默认付款应用的选择界面中包括一个或多个NFC管理应用(用于管理一个或多个NFC应用)的选项和一个或多个NFC应用的选项。
例如，默认付款应用的选择界面中可以包括图2中的NFC APP 201中的“钱包”(如华为钱包)应用(即NFC管理应用)，以及“车钥匙”应用、“社保卡”应用和“NFC支付APP”应用(即NFC应用)的选项。其中，“钱包”应用是用于管理NFC应用“银 行卡”应用和“公交卡”应用的NFC管理应用。例如，“NFC支付APP”应用可以为图2所示的“京东支付”应用。
如果用户点击默认付款应用的选择界面中的一个NFC应用(独立NFC应用，如“社保卡”应用)的选项，则表示用户选择该NFC应用(如“社保卡”应用)作为默认的NFC应用。其中，需要注意的是，本申请实施例中的“独立NFC应用”的NFC管理应用仅包括一个NFC应用。即该NFC管理应用中仅管理一个NCF应用。例如，假设图2所示的“社保卡”应用是独立NFC应用。如果用户点击默认付款应用的选择界面中的“社保卡”应用的选项，则表示用户选择“社保卡”应用作为默认的NFC应用。如图2所示，“社保卡”应用承载在SE 1中。
如果用户点击默认付款应用的选择界面中的一个NFC管理应用(该NFC管理应用管理多个NFC应用，如“钱包”应用管理“银行卡”应用和“公交卡”应用)的选项，那么用户则可以继续在该NFC管理应用(如“钱包”应用)所管理的NFC应用(如“银行卡”应用和“公交卡”应用)中选择一个NFC应用(如“银行卡”应用)作为默认付款应用。
用户选择默认的NFC应用后，NFCC则可以修改NFCC中的路由表(即执行图2中的S2)，使得路由表指向默认的NFC应用所在的SE。如此，NFCC接收到任意一个交易指令后，NFCC中的路由表均指向该SE。即NFC控制器的路由指向该SE。
例如，假设用户选择默认的NFC应用为图2所示的“社保卡”应用，图2所示的“社保卡”应用承载在SE 1中。那么，NFCC则可以修改NFCC中的路由表(即执行图2中的S2)，使得路由表指向SE 1。如此，NFCC接收到任意一个交易指令后，NFCC中的路由表均指向SE 1。即NFC控制器的路由指向该SE 1。
又例如，假设用户选择默认的NFC应用为图2所示的“银行卡”应用，图2所示的“银行卡”应用承载在SE 2中。那么，NFCC则可以修改NFCC中的路由表(即执行图2中的S2)，使得路由表指向SE 2。如此，NFCC接收到任意一个交易指令后，NFCC中的路由表均指向SE 2。即NFC控制器的路由指向该SE 2。
一般而言，只有NFCC的路由所指向的SE可以承接NFC交易，即处理交易指令。而当交易指令要访问承载在其他SE中的NFC应用时，交易则无法进行。该其他SE不是NFC控制器的路由所指向的SE。具体的，由于NFC控制器的路由无法指向交易指令所要访问的NFC应用所在的SE；因此，NFC控制器无法向该SE发送交易指令，从而该SE中的NFC应用无法执行该交易指令，进而导致交易无法完成。
例如，结合上述图1和图2，以NFCC的路由指向以SIM卡形式存在的SE 1为例。在电子设备100靠近读卡器(或POS机具)时，电子设备可以接收到读卡器(或POS机具)发送的交易指令。如果该交易指令所访问的NFC应用(如图2所示的“社保卡”应用)承载在SE 1中，则NFC控制器可以向SE 1发送该交易指令，由SE 1中对应的NFC应用(如图2所示的“社保卡”应用)执行交易指令，以完成交易。如果该交易指令所访问的NFC应用(如图2所示的“车钥匙”应用)没有承载在SE 1中，而是承载在SE 2或SE 3中(如图2所示的“车钥匙”应用承载在SE 2中)，由于NFC控制器的路由无法指向SE 2或SE 3，NFC控制器则无法向SE 2或SE 3发送交易指令，从而SE 2或SE 3中的NFC应用无法执行该交易指令，进而导致交易无法完成。
本实施例提供一种SE的自动路由方法，该方法可以应用于有多个SE的电子设备，该电子设备具备NFC功能。本实施例提供的方法，即使电子设备有多个SE，也可以自动 路由到交易指令访问的NFC应用所在的SE。

其中，以下实施例中所涉及的技术方案均可以在具有上述硬件架构的电子设备100中实现。以下对本实施例提供的SE的自动路由方法进行详细介绍。为了便于理解，以下 实施例中均以电子设备有三个SE(如参见图1B所示)为例进行介绍。
其中，本申请实施例中NFC应用的标识可以为第一标识或第二标识，第一标识是标准NFC应用的标识，而第二标识是非标准NFC应用的标识。例如，第一标识可以是AID，标准NFC应用是指支持AID的NFC应用。而第二标识不是AID，非标准NFC应用不支持AID。
本申请实施例提供一种SE的自动路由方法。电子设备100可以从服务器下载多个NFC应用。该多个NFC应用可以承载在电子设备100的一个或多个SE中。每个SE可以承载至少一个NFC应用。
其中，用户可以在电子设备100中设置默认的NFC应用，如用户设置NFC应用1为电子设备100中默认的NFC应用。假设该NFC应用1承载在SE 1中，则电子设备100的NFCC的路由指向SE 1。但是，电子设备100靠近读卡器或POS机具时，电子设备100接收到的交易指令所要访问的NFC应用可能不是SE 1中的NFC应用。例如，交易指令所要访问的NFC应用可能是NFC应用2，NFC应用2承载在SE 2中。由于电子设备100的NFCC的路由未指向SE 1，因此，该交易无法进行。
而本申请实施例中，无论NFCC的路由是否指向交易指令所要访问的NFC应用所在的SE，电子设备100(电子设备100的NFCC)都可以自动路由到交易指令所要访问的NFC应用所在的SE，与读卡器或POS机具交互完成交易。
电子设备100的NFCC可保存多个NFC应用的第一标识和SE位置信息。该SE位置信息指示承载对应NFC应用的SE。例如，电子设备100的NFCC可以维护一个路由表。电子设备100的NFCC可以在路由表中配置一个或多个NFC应用的路由信息，该NFC应用的路由信息可以包括该NFC应用的第一标识和SE位置信息。该SE位置信息指示承载该NFC应用的SE，即该NFC应用的承载在电子设备100的哪一个SE中。例如，上述第一标识可以为NFC应用的AID。当然，第一标识包括但不限于AID。
之后，电子设备100靠近读卡器或POS机具时，电子设备100的NFCC可以接收到来自读卡器或POS机具的交易指令。该交易指令中可能包括第一标识(如AID)，或者该交易指令中也可能不包括第一标识。因此，如图5A所示，电子设备100的NFCC在接收到交易指令后，可以判断该交易指令中是否包含AID。如果该交易指令中包括AID，则可以从上述路由表中查找该AID对应的SE位置信息；然后，将接收到交易指令传输至该SE位置信息所指示的SE(即第一目标SE)。也就是说，NFCC可以根据交易指令中携带的第一标识，自动路由至交易指令所要访问的NFC应用所在的SE。
进一步的，该SE位置信息所指示的SE(即第一目标SE)接收到交易指令后，则可以从第一目标SE承载的NFC应用中确定第一目标NFC应用(即交易指令所访问的NFC应用)，并运行第一目标NFC应用，执行交易指令。
具体的，第一目标SE可以向交易指令所访问的NFC应用(即第一目标NFC应用)发送交易指令，由第一目标NFC应用执行该交易指令，以便完成交易。
其中，本申请实施例中，电子设备100靠近读卡器或POS机具，具体可以为：电子设备100与读卡器或POS机具之间的距离小于预设距离阈值。其中，本申请实施例中的读卡器或POS。
示例性的，请参考表1，其示出图2或图4所示的多个NFC应用的AID标识。
表1
Figure PCTCN2020085520-appb-000001
Figure PCTCN2020085520-appb-000002
如表1所示，“社保卡”应用的AID为AID-1；“银行卡”应用的AID为AID-2；“公交卡”应用的AID为AID-3；“车钥匙”应用的AID为AID-4；“NFC支付”应用的AID为AID-5。例如，“NFC支付APP”应用可以为“美团支付”应用，或者图2所示的“京东支付”应用等。
示例性的，请参考表2，其示出本申请实施例提供的一种路由表实例。
表2
Figure PCTCN2020085520-appb-000003
其中，上述SE位置信息可以为承载该NFC应用的SE的标识。如表2所示，SE位置信息1可以为SE 1的标识，SE位置信息2可以为SE 2的标识，SE位置信息3可以为SE 3的标识。
并且，由表2可知：AID-1对应SE位置信息1，表1所示的AID-1所标识的“社保卡”应用承载在SE 1(即图4所示的以SIM卡形式存在的SE 1)；表1所示的AID-2所标识的“银行卡”应用、AID-3所标识的“公交卡”应用和AID-4所标识的“车钥匙”应用承载在SE 2(即图4所示的与NFC芯片一起封装的SE 2)中；表1所示的AID-5所标识的“NFC支付APP”应用承载在SE 3(即图4所示的以HCE形式存在的SE 3)中。
可以理解，上述SE位置信息所指示的SE可能是NFCC的路由所指向的SE，也可能不是NFCC的路由所指向的SE。电子设备100查找到上述AID对应的SE位置信息后，可以判断该SE位置信息所指示的SE是为NFCC的路由所指向的SE。如果该SE是NFCC的路由所指向的SE，NFCC可以直接将接收到交易指令传输至该SE，由该SE中交易指令所访问的NFC应用执行该交易指令，完成交易。如果该SE不是NFCC的路由所指向的SE，NFCC可以修改路由指向该SE，然后将接收到交易指令传输至该SE，由该SE中交易指令所访问的NFC应用执行该交易指令，完成交易。
例如，假设默认的NFC应用为图4所示的“社保卡”应用，该“社保卡”应用承载在图4所示的SE 1中，NFCC的路由指向SE 1。
如果电子设备100的NFCC接收到携带AID-1的交易指令1。NFCC可以从表2所示的路由表中查找到AID-1对应的SE位置信息1。该SE位置信息1指示该交易指令1所访 问的NFC应用承载在SE 1中。电子设备100则可以直接将交易指令1传输至SE 1，由SE 1中交易指令1所访问的NFC应用(如表1所示，AID-1对应的“社保卡”应用)执行交易指令1，完成交易。
如果电子设备100的NFCC接收到携带AID-3的交易指令2。NFCC可以从表2所示的路由表中查找到AID-3对应的SE位置信息2。该SE位置信息2指示该交易指令2所访问的NFC应用承载在SE 2中。电子设备100则可以修改路由指向该SE 2；然后，将交易指令2传输至SE 2，由SE 2中交易指令2所访问的NFC应用(如表1所示，AID-3对应的“公交卡”应用)执行交易指令2，完成交易。
本申请实施例中，一个NFC管理应用可以管理一个或多个NFC应用。NFC管理应用携带其所管理的NFC应用的第一标识和SE位置信息。其中，电子设备100安装NFC应用的(如第一目标NFC应用)NFC管理应用时，该NFC管理应用可以向电子设备100的默认付款应用注册。如此，默认付款应用便可以向电子设备100的NFCC传输该NFC应用的第一标识和SE位置信息。电子设备100的NFCC便可以保存该NFC应用的第一标识和SE位置信息。
示例性的，电子设备100的NFCC可以维护一个路由表，该路由表中包括多个NFC应用的AID和SE位置信息的对应关系。如此，即使电子设备100中包括多个SE，电子设备100也可以根据交易指令中携带的AID，在路由表中查找到该交易指令所要访问的NFC应用的SE位置信息，确定出承载该交易指令所要访问的NFC应用的SE。即NFCC可以根据交易指令中携带的第一标识，自动路由至交易指令所要访问的NFC应用所在的SE。
在本申请实施例中，所述的交易指令可以是任何类型读卡器(如，手持移动读卡器，固定读卡器)或任何类型POS机具(如，手持移动POS机具，固定POS机具)所发出指令。其可以是各种类型或各种帧格式的指令。如，交易指令可以是应用协议数据单元(Application Protocol Data Unit，APDU)帧格式、单字节短帧格式、长帧格式等帧格式的指令。又如，交易指令可以是14443类型(TYPE)A，14443 TYPE B，国际标准化组织(International Standard Organization，ISO)18092，ISO15693等类型的指令。
本申请实施例这里对NFCC配置路由表的方法进行说明。
在一些实施例中，在安装NFC应用的NFC管理应用时，该NFC应用对应在表1所示的路由表中的路由信息可以根据电子设备100的DH下发的路由配置命令来配置。其中，该NFC应用的路由信息可以包括该NFC应用的AID和SE位置信息。SE位置信息用于指示该NFC应用承载在哪一个SE中。其中，上述默认付款应用由DH管理。
具体的，某NFC应用(如“社保卡”应用)下载到了电子设备100的某个SE(如以SIM卡形式存在的SE 1)中。电子设备100的该SE(如SE 1)在确定出该NFC应用下载到该SE成功后，可以向电子设备100的DH发送用于指示该NFC应用已下载成功的消息。电子设备100的DH接收到该消息后，可以向电子设备100的NFCC发送路由配置命令。该路由配置命令可以是在电子设备100的本地预先定义的，也可以是提供该NFC应用下载资源的服务器下发给电子设备100的DH的。该路由配置命令用于指示NFCC在上述路由表中配置该NFC应用的路由信息。电子设备100的NFCC根据该路由配置命令，便可以在上述路由表中配置该NFC应用的路由信息。该路由信息可以包括，该NFC应用的AID与SE位置信息。
例如，以在NFCC中配置“门禁卡”应用的路由信息为例，对在上述路由表中进行路由配置的过程进行介绍。对于“社保卡”应用、“车钥匙”应用以及“公交卡”应用等 的路由信息配置过程的具体描述与“门禁卡”应用对应的路由信息配置过程的具体描述类似。
其中，根据用户的操作，电子设备100可以下载“门禁卡”应用到电子设备100的SE中。如图4所示，该“门禁卡”应用下载到了SE 3中。在该“门禁卡”应用下载到SE 3成功后，该SE 3可以向电子设备100的DH发送指示成功的消息。电子设备100的DH响应于该消息，可以向电子设备100的NFCC发送路由配置命令。如该路由配置命令中包括：“门禁卡”应用的路由信息，如AID-6和SE位置信息3。电子设备100的NFCC根据DH下发的路由配置命令便可以进行路由配置，即在表2所示的路由表中配置“门禁卡”应用的路由信息。例如，配置的路由信息如表3所示的路由表中的路由信息(AID-6和SE位置信息3)。这样，“门禁卡”应用的路由信息便配置完成，后续可利用该路由信息确定出交易指令是否要访问该NFC应用。
表3

可以理解，在“门禁卡”应用下载到SE 3成功后，该SE 3可以向电子设备100的DH发送指示成功的消息。电子设备100的DH响应于该消息，可以将“门禁卡”应用注册到默认付款应用中(即执行图4所示的Sa)。然后，电子设备100的DH可以通过向电子设备100的NFCC发送路由配置命令，指示电子设备100的NFCC在路由表中配置该路由信息(即执行图4所示的Sb)。
可以理解，上述NFC管理应用(如“钱包”应用)可以管理一个或多个NFC应用。例如，如图2或图4所示的“钱包”应用(即NFC管理应用)管理“银行卡”应用和“公交卡”应用这两个NFC应用。其中，不同的NFC应用所支持的NFC业务的验证方式不同。具体的，如图5B所示，“银行卡”应用对应要求验证模式，需要通过用户验证(如密码验证、指纹验证、人脸验证、虹膜认证、声纹认证、行为认证等)，才可以完成交易。而“公交卡”应用则对应直接刷卡模式，不需要用户验证便可以完成交易。
例如，针对“公交卡”应用，电子设备100与读卡器或POS机具(如公交POS机)的交互过程可以包括：(1)公交POS机一直发送NFC场强信号；(2)电子设备100靠近公交POS机时，可接收到公交POS机发送的场强信号；(3)电子设备100的NFCC不需要用户验证便可响应于该场强信号向公交POS机回复响应；(4)公交POS机接收到响应后，向电子设备100发送交易指令；(5)电子设备100的NFCC接收交易指令，并根据交易指令完成交易。
又例如，以使用“银行卡”应用在超市收银台付款为例，电子设备100与超市POS机的交互过程可以包括：(1)超市POS机一直发送NFC场强信号；(2)电子设备100 靠近超市POS机时，可接收到超市POS机发送的场强信号；(3)电子设备100需要调起用户验证(如密码验证、指纹验证、人脸验证、虹膜认证、声纹认证、行为认证等)，在用户验证成功后，才会向超市POS机发送响应；(4)超市POS机接收到响应后，向电子设备100发送交易指令；(5)电子设备100的NFCC接收交易指令，并根据交易指令完成交易。
但是，请参考图6中的(a)，如果用户在上述“钱包”应用中，将“公交卡”应用设置为默认的NFC应用，那么该“钱包”应用中的其他NFC应用(如“银行卡”应用)则会被禁用。此时，如果电子设备100靠近超市POS机，则电子设备100与超市POS机之间的交易则可能会因为无法调起用户验证而失败。如果用户想要使用“银行卡”应用付款，则可以在“钱包”应用中，将“银行卡”应用设置为默认的NFC应用，那么该“钱包”应用中的其他NFC应用(如“公交卡”应用)则会被禁用。此时，如果电子设备100靠近公交POS机，则电子设备100与公交POS机之间的交易则会失败。如果用户想要再次使用“公交卡”应用付款，则可以重新再“钱包”应用中，将“公交卡”应用设置为默认的NFC应用。在用户的日常生活中，该用户可能要频繁的在“钱包”应用中手动切换设置默认的NFC应用，用户体验较差。
基于此，本申请实施例中，提出“直刷为常态，验证为临时”的概念，电子设备100的一个NFC管理应用可以管理的NFC应用包括：第一NFC应用(如“公交卡”应用、“社保卡”应用，或者“车钥匙”应用等)和第二NFC应用(如“银行卡”应用)。其中，第一NFC应用支持的NFC业务的验证方式为直接刷卡模式，不需要进行用户验证。第二NFC应用支持的NFC业务的验证方式为要求验证模式，需要进行用户验证。其中，用户验证至少为密码验证、指纹验证、虹膜认证、声纹认证、行为认证或人脸验证中的任一项。
上述SE的自动路由方法，以及本申请实施例提供的一种NFC应用自动激活的方法可以包括以下方案：电子设备100中的第一NFC应用和第二NFC应用承载在第一SE中；第一NFC应用可以为常态下默认的NFC应用，第二NFC应用可以为临时默认的NFC应用。具体的，电子设备100中默认的NFC应用可以为上述第一NFC应用(该第一NFC应用可以由用户设置为默认的NFC应用)；如此，用户随时使用该电子设备100都可以与第一NFC应用对应的读卡器或POS机具完成交易。而当用户想要使用上述第二NFC应用付款时，则可以在电子设备100输入预设快捷操作。响应于该预设快捷操作，电子设备100可以临时将上述第二NFC应用设置为默认的NFC应用，以使电子设备100可以与第二NFC应用对应的读卡器或POS机具完成交易。
本申请实施例中，即使一个SE中包括直接刷卡模式的第一NFC应用(如“公交卡”应用、“社保卡”应用，或者“车钥匙”应用等)和要求验证模式的第二NFC应用(如“银行卡”应用)，也不需要用户频繁设置默认的NFC应用。电子设备100可以随时与第一NFC应用对应的读卡器或POS机具完成交易；并且，可以响应于预设快捷操作，与第二NFC应用对应的读卡器或POS机具完成交易。
例如，上述预设快捷操作至少可以为：用户对电子设备100的电源键(或者称为锁屏键)的双击操作，用户对电子设备100的预设敲击操作(如对电子设备100的后壳的N次连续敲击操作，N≥2，N为正整数)，用户对电子设备100的Home键的预设操作(如长按操作等)，用户向电子设备100输入预设指纹信息等中的任意一种。
进一步的，在电子设备100与第二NFC应用对应的读卡器或POS机具完成交易后， 或者，从电子设备100将上述第二NFC应用设置为默认的NFC应用开始的预设时间后，电子设备100中默认的NFC应用重新切换为上述第一NFC应用。例如，上述预设时间可以为1分钟，2分钟或者30秒等。该预设时间可以由用户设置，或者预设时间可以是预先配置在电子设备100中的固定时间长度。
示例性的，假设上述第二NFC应用是上述实例中的“银行卡”应用，第一NFC应用是“公交卡”应用。“银行卡”应用和“公交卡”应用包括在“钱包”应用中，用户可以在“钱包”应用中管理“银行卡”应用和“公交卡”应用。例如，用户可以在“钱包”应用中设置“银行卡”应用或“公交卡”应用为电子设备100默认的NFC应用。
例如，请参考图6中的(a)，用户可以设置“公交卡”应用为默认的NFC应用。其中，用户在“钱包”应用中，设置“公交卡”应用为默认的NFC应用的方法这里不予赘述。用户设置“公交卡”应用为默认的NFC应用后，该“公交卡”应用可以作为电子设备100常态下默认的NFC应用。如果电子设备100靠近公交POS机，电子设备100的NFCC不需要进行用户验证，便可以由“公交卡”应用执行交易指令，与公交POS机完成交易。用户想要使用“银行卡”应用付款(如超市购物)时，则可以向电子设备100输入预设快捷操作，然后将电子设备100靠近超市POS机。由于响应于预设快捷操作，电子设备100可以将“银行卡”应用设置为临时默认的NFC应用；因此，当电子设备100靠近超市POS机时，电子设备100可以成功调起用户验证，并在用户验证成功后，由“银行卡”应用执行交易指令，与超市POS机完成交易。随后，在电子设备100与超市POS机完成交易后(图6中的(b)未示出)，或者，从电子设备100将“银行卡”应用设置为默认的NFC应用开始的预设时间(如1分钟)后，电子设备100中默认的NFC应用重新切换为“公交卡”应用。如此，电子设备100中默认的NFC应用又切换为直接刷卡模式的“公交卡”应用。
本申请实施例中，电子设备100可以将直接刷卡模式的第一NFC应用(如“公交卡”应用、“社保卡”应用，或者“车钥匙”应用等)设置为常态下默认的NFC应用；将要求验证模式的第二NFC应用(如“银行卡”应用)设置为临时默认的NFC应用。如此，用户随时使用该电子设备100都可以与第一NFC应用对应的读卡器或POS机具完成交易。而当用户想要使用上述第二NFC应用付款时，则可以在电子设备100输入预设快捷操作。响应于该预设快捷操作，电子设备100可以临时将上述第二NFC应用设置为默认的NFC应用，以使电子设备100可以与第二NFC应用对应的读卡器或POS机具完成交易。
可以理解，一个NFC管理应用中可以包括一个第一NFC应用。或者，一个NFC管理应用中可以包括多个第一NFC应用。例如，“钱包”应用中可以包括“公交卡”应用、“社保卡”应用和“车钥匙”应用等多个NFC应用。
当“钱包”应用中包括“公交卡”应用、“社保卡”应用和“车钥匙”应用等多个NFC应用时，电子设备100可以根据读卡器或POS机具发送的交易指令中的AID，激活对应的NFC应用，由对应的NFC应用执行该交易指令，完成交易。
需要注意的是，为了保证上述用户验证的安全性，上述用户验证(如图2和图4所示的指纹验证)，可以在可信执行环境(trust execution environment，TEE)中进行。而用户对默认的NFC应用的设置，以及NFC应用的注册等对安全性要求比较低的流程则可以在可以执行富指令的普通执行环境(rich execution environment，REE)中执行。
可以理解，不是所有的NFC应用都支持并使用第一标识(如AID)。以第一标识是AID为例。例如，一些公交卡不支持并使用AID。因此，在一些实施例中，电子设备100 的NFCC接收到的交易指令中是不包括AID的。
基于这种情况，上述路由表中可以包括非标卡缺省项。该非标卡缺省项用于在交易指令中不包含AID时，指向电子设备100的当前场景信息对应的SE(即第二目标SE)。电子设备100(如电子设备100的NFC管理应用，如“钱包”应用)可以保存每个非标准NFC应用的查询信息。其中，一个非标准NFC应用的查询信息可以包括：该非标准NFC应用的使用场景信息、SE位置信息和第二标识。非标准NFC应用的使用场景信息用于指示使用该非标准NFC应用的场景信息。
第二标识：该第二标识用于标识非标准NFC应用，第二标识不是第一标识(如AID)。该第二标识可以是电子设备100为该非标准NFC应用分配的编号。
使用场景信息：该使用场景信息至少可以包括地理位置信息、时间信息和操作信息中的一项或多项。
上述地理位置信息用于指示该非标准NFC应用可被使用的地理位置。如西安的“公交卡”应用可被使用的地理位置为西安市，深圳的“公交卡”应用可被使用的地理位置为深圳市。又例如，家门的“社保卡”应用可被使用的地理位置为家对应的地理位置，“车钥匙”应用可被使用的地理位置为车库。
上述时间信息用于指示对应非标准NFC应用可被使用的时间。上述时间信息可以为电子设备100统计的用户经常使用该非标准NFC应用的时间。例如，电子设备100统计得到用户在7:00-7:30和18:00-18:30这两个时间段内经常使用“社保卡”应用，那么该“社保卡”应用的时间信息则可以为7:00-7:00和18:00-18:30。
上述操作信息用于指示非标准NFC应用被使用前用户对电子设备100的操作。例如，假设“社保卡”应用的操作信息可以为用户对电子设备100的机身的双击操作，“车钥匙”应用的操作信息可以为用户对电子设备100的机身的摇晃操作。
SE位置信息：该SE位置信息指示承载该非标准NFC应用的SE，即该非标准NFC应用的承载在电子设备100的哪一个SE中。
例如，上述电子设备100(例如，图7所示的场景管理模块701)可以保存一个或多个非标准NFC应用的使用场景信息、SE位置信息和第二标识。例如，电子设备100(例如，图7所示的场景管理模块701)可以维护一个非标卡信息表。该非标卡信息表中可以包括电子设备100中安装的非标准NFC应用的查询信息。非标准NFC应用的查询信息可以包括非标准NFC应用的使用场景信息、SE位置信息和第二标识。
需要注意的是，图7所示的场景管理模块701维护的非标卡信息表中的查询信息可以是电子设备100中安装对应非标准NFC应用时配置的。其中，电子设备100中安装非标准NFC应用时，在电子设备100(如图7所示的场景管理模块701)中配置该非标准NFC应用的查询信息的方法在以下实施例中介绍。其中，本申请实施例中的场景管理模块701可以为用于管理多个NFC应用的NFC管理应用，如上述“钱包”应用。
例如，假设电子设备100中管理了图7所示的非标准NFC应用1(如深圳市的“公交”应用)、非标准NFC应用2(如西安市的“公交”应用)和非标准NFC应用3(如上海市的“公交卡”应用)这三个非标准NFC应用。其中，非标准NFC应用1的标识(如编号)为标识1、非标准NFC应用1承载在SE 1中，使用非标准NFC应用1的场景信息为场景信息1。非标准NFC应用2的标识(如编号)为标识2、非标准NFC应用2承载在SE 2中，使用非标准NFC应用2的场景信息为场景信息2。非标准NFC应用3的标识(如编号)为标识3、非标准NFC应用2承载在SE 3中，使用非标准NFC应用3的场景信息 为场景信息3。
请参考表4，为本申请实施例提供的一种非标卡信息表实例，其示出了上述非标准NFC应用1(如深圳市的“公交”应用)、非标准NFC应用2(如西安市的“公交”应用)和非标准NFC应用3(如上海市的“公交卡”应用)的查询信息。

之后，电子设备100靠近读卡器或POS机具时，电子设备100的NFCC可以接收到来自读卡器或POS机具的交易指令。该交易指令中可能包括AID，或者该交易指令中也可能不包括AID。因此，如图5A所示，电子设备100的NFCC在接收到交易指令后，可以判断该交易指令中是否包含AID。如果该交易指令中不包括AID，电子设备100则可以获取该电子设备100当前的场景信息。电子设备100可以从上述非标卡信息表中查找与当前的场景信息对应的非标准NFC应用的标识(如标识2)和SE位置信息(如该SE位置信息指示SE 2)。电子设备100的NFCC配置路由表中的非标卡缺省项指向查找到的SE位置信息所指示的SE(即第二目标SE，如SE 2)。如此，电子设备100的NFCC便可以将交易指令传输至非标卡缺省项所指向的SE(即第二目标SE，如SE 2)。
进一步的，电子设备100还可以向该SE位置信息所指示的SE(如SE 2)通知查找到的非标准NFC应用的标识(如标识2)。如此，该SE位置信息所指示的SE(如SE 2)接收到交易指令后，则可以自动激活上述标识(如标识2)对应的非标准NFC应用(即第二目标NFC应用)，并执行该交易指令，以便完成交易。
示例性的，本申请实施例这里结合附图7，对上述NFC的交易过程进行详细介绍：
首先，电子设备100靠近读卡器或POS机具时，电子设备100的NFCC接收到来自读卡器或POS机具的交易指令。电子设备100的NFCC确定该交易指令中不包括AID。电子设备100的场景信息获取模块702获取电子设备100当前的场景信息。
其次，场景信息获取模块702向场景管理模块701传输当前的场景信息。场景管理模块701从上述非标卡信息表中查找与当前的场景信息对应的非标准NFC应用的标识(如标识2)和SE位置信息(如该SE位置信息指示SE 2)。
随后，场景管理模块701可以向NFCC指示该SE位置信息，使得NFCC配置路由表中的非标卡缺省项指向该SE位置信息所指示的SE(如SE 2)。如此，NFCC可以将交易指令传输至非标卡缺省项所指向的SE(如SE 2)。
并且，场景管理模块701还可以向上述SE位置信息所指示的SE(如SE 2)通知查找到的非标准NFC应用的标识(如标识2)。这样，上述SE位置信息所指示的SE(如SE 2)接收到交易指令后，则可以自动激活上述标识(如标识2)对应的非标准NFC应用，并执行该交易指令，以便完成交易。
其中，上述场景信息至少可以包括地理位置信息、时间信息和操作信息中的一项或多项。那么上述场景信息获取模块702则可以包括地理位置获取模块(如GPS定位模块)和时间信息获取模块(如电子设备100中的是时钟和日历等)等。
可以理解，上述与当前的场景信息对应的SE位置信息所指示的SE(如SE 2)可能是NFCC的路由所指向的SE，也可能不是NFCC的路由所指向的SE。电子设备100查找到上述SE位置信息后，可以判断该SE位置信息所指示的SE是否为路由表中的非标卡缺省项所指向的SE。如果该SE是非标卡缺省项所指向的SE，NFCC可以直接将接收到交易指令传输至该SE，由该SE自动激活与当前的场景信息对应的标识所指示的非标准NFC应用，执行该交易指令完成交易。如果该SE不是非标卡缺省项所指向的SE，NFCC则可以配置路由表中的非标卡缺省项指向该SE，然后将接收到交易指令传输至该SE，由该SE自动激活与当前的场景信息对应的标识所指示的非标准NFC应用，执行该交易指令完成交易。
例如，假设默认的NFC应用为图7所示的非标准NFC应用1，该非标准NFC应用1承载在图7所示的SE 1中，NFCC的路由表中的非标卡缺省项指向SE 1。
如果电子设备100的NFCC接收到携带交易指令3，该交易指令3中不包括AID，电子设备100获取到电子设备100当前的场景信息为表4所示的场景信息2，那么电子设备100可以从表4可以查找到场景信息2对应的标识2和SE位置信息2。该标识2是非标准NFC应用2的标识，该SE位置信息2指示SE 2。电子设备100的NFCC则可以配置路由表中的非标卡缺省项指向SE 2。然后，将交易指令3传输至SE 2，由SE 2自动激活标识2所指示的非标准NFC应用2，激活的非标准NFC应用2执行交易指令3完成交易。
如果电子设备100的NFCC接收到携带交易指令4，该交易指令4中不包括AID，电子设备100获取到电子设备100当前的场景信息为表4所示的场景信息1，那么电子设备100可以从表4可以查找到场景信息1对应的标识1和SE位置信息1。该标识1是非标准NFC应用1的标识，该SE位置信息1指示SE 1。电子设备100的NFCC则可以配置路由表中的非标卡缺省项指向SE 1，直接将交易指令4传输至SE 1，由SE 1自动激活标识1所指示的非标准NFC应用1，激活的非标准NFC应用1执行交易指令4完成交易。
本申请实施例这里对电子设备100配置上述非标卡信息表的方法进行说明。
在一些实施例中，在安装NFC应用时，该NFC应用对应在表4所示的非标卡信息表中的查询信息可以根据电子设备100的DH下发的路由配置命令来配置。其中，该非标准NFC应用的查询信息可以包括该非标准NFC应用的标识、SE位置信息和场景信息。
具体的，在安装某非标准NFC应用(如图7所示的非标准NFC应用4)时，该NFC应用下载到了电子设备100的某个SE(如SE 2)中。电子设备100的该SE(如SE 2)在确定出该非标准NFC应用下载到该SE成功后，可以向电子设备100的DH发送用于指示该非标准NFC应用已下载成功的消息。电子设备100的DH响应于该消息，可以将该非标准NFC应用(如图7所示的非标准NFC应用4)注册到默认付款应用中(即执行图7所示的S-A)。其中，DH响应于该消息将图7所示的非标准NFC应用4注册到默认付款应用时，可以在该默认付款应用中配置该非标准NFC应用4的标识4、指示SE 2的SE位置信息和场景信息4。最后，电子设备100的DH可以在上述场景管理模块701维护的非标卡信息表中配置该非标准NFC应用(如图7所示的非标准NFC应用4)的查询信息(即执行图7所示的S-B)。例如，非标准NFC应用4的查询信息如表5所示的非标卡信息表中的查询信息(标识4、SE位置信息4和场景信息4)。这样，非标准NFC应用4的查询信息便配置完成，后续可利用该查询信息确定出交易指令是否要访问该NFC应用。
表5

需要注意的是，部分非标准NFC卡的场景信息是按照上述方式，在下载该非标准NFC应用时配置的。例如，各地的“公交卡”应用的地理位置信息是下载该“公交卡”应用时配置的。而部分非标准NFC卡的场景信息则是在用户使用该非标准NFC卡一段时间后，电子设备100统计得到的用户经常使用该非标准NFC应用的场景信息(如地理位置信息和/时间信息)。例如，“社保卡”应用的场景信息是在用户使用该“社保卡”应用一段时间后，电子设备100统计得到的用户经常使用“社保卡”应用的场景信息。
在一些实施例中，以上述场景信息是地理位置信息为例。如图8所示，北京“公交卡”应用承载在SE 1中，深圳“公交卡”应用承载在SE 2中，西安“公交卡”应用承载在SE 3中。其中，北京“公交卡”应用、深圳“公交卡”应用和西安“公交卡”应用均为非标准NFC应用，不支持AID。西安“公交卡”应用的标识为标识a、场景信息为西安，SE位置信息指示西安“公交卡”应用承载在SE 3中。
当用户手持电子设备100靠近公交车上的POS机具时，电子设备100的NFCC可以接收POS机具发送的交易指令。电子设备100在接收到交易指令后，可以获取用户当前所处的地理位置信息。如果获取到的地理位置表明用户当前处于西安，电子设备100的NFCC可以将接收到的交易指令传输至SE 3，SE 3自动激活西安“公交卡”应用，并执行该交易指令，如从该西安“公交卡”应用中扣除相应的金额。
例如，如图8所示，场景信息获取模块(如地理位置获取模块)702可以获取当前的地理位置信息，并执行S(1)向场景管理模块(如公交卡管理APP，即NFC管理应用)701发送当前的地理位置信息。场景管理模块(如公交卡管理APP，即NFC管理应用)701可以从非标卡信息表中查找与地理位置信息“西安”对应的西安“公交卡”应用的标识a和指示SE 3的SE位置信息。然后，场景管理模块701可以向NFCC指示该SE位置信息，使得NFCC配置路由表中的非标卡缺省项指向该SE位置信息所指示的SE 3。如此，NFCC可以将交易指令传输至非标卡缺省项所指向的SE 3。并且，场景管理模块701还可以向SE 3通知查找到的西安“公交卡”应用的标识a。这样，上述SE 3接收到交易指令后，则可以自动激活标识a对应的西安“公交卡”应用，并执行该交易指令，以便完成交易。
在一些实施例中，以上述场景信息包括地理位置信息和时间信息为例。假设“车钥匙”应用承载在以SIM卡形式存在的SE 1中。电子设备100统计出用户在7:30-7:50这个时间段内，在地理位置1(如地下车库1)经常使用该“车钥匙”应用。那么如果NFCC接收到了交易指令，可以在获取到当前系统时间(或者说是，接收到交易指令的时间)处于7:30-7:50这个时间段内，且电子设备100的位于地理位置1时，则可以自动激活该车钥匙应用301。也就是说，可以在当前系统时间处于7:30-7:50这个时间段内，且电子设备100的位于地理位置1时，由非标卡缺省项指向的SE 1自动运行“车钥匙”应用。这样，在用户使用电子设备100靠近车门时，无需用户手动激活“车钥匙”应用便 可打开车门。
本申请实施例提供的SE的自动路由方法，即使一些NFC应用不支持AID，电子设备100也可以在接收到交易指令后，根据电子设备100当前的场景信息，自动路由至交易指令所要访问非标准NFC应用所在的SE。
本申请实施例可以根据上述方法示例对上述电子设备进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。需要说明的是，本申请实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
其中，上述方法实施例中的场景管理模块701和场景信息获取模块702可以集成在电子设备100的处理器(如处理器310)中实现。
本申请实施例提供一种NFC芯片，该NFC芯片包括NFCC(即NFC控制器)；NFCC保存了多个NFC应用的第一标识和安全单元SE位置信息，SE位置信息指示承载对应NFC应用的SE。NFCC接收交易指令；NFCC响应于交易指令中携带第一标识，从NFC控制保存的SE位置信息中，查找交易指令携带的第一标识对应的SE位置信息；NFCC根据查找到的SE位置信息,从至少两个SE中确定第一目标SE；NFCC向第一目标SE发送交易指令。例如，上述第一标识可以是AID。
进一步的，上述NFCC还用于在下载第一目标NFC应用时，保存第一目标NFC应用的第一标识和第一目标NFC应用的SE位置信息，第一目标NFC应用的SE位置信息指示承载第一目标NFC应用的第一目标SE。
进一步的，上述NFCC向第一目标SE发送交易指令，包括：NFCC具体用于：如果第一目标SE是NFCC的路由所指向的SE，NFCC可以直接向第一目标SE发送交易指令；如果第一目标SE不是NFCC的路由所指向的SE，NFCC可以修改路由指向第一目标SE，然后向第一目标SE发送交易指令。
进一步的，上述NFCC保存路由表，路由表中包括多个NFC应用的第一标识和SE位置信息。路由表还包括非标卡缺省项，非标卡缺省项用于在交易指令未携带第一标识的情况下，指向电子设备的当前场景信息对应的SE。NFCC还用于在交易指令中未携带第一标识的情况下，接收用于指示第二目标SE的指示信息；配置非标卡缺省项指向第二目标SE。NFCC还用于向非标卡缺省项指向的第二目标SE发送交易指令。
进一步的，上述NFCC还用于向非标卡缺省项指向的第二目标SE发送交易指令，包括：NFCC，具体用于：如果第二目标SE是非标卡缺省项所指向的SE，NFCC可以直接向非标卡缺省项指向的第二目标SE发送交易指令；如果第二目标SE不是非标卡缺省项所指向的SE，NFCC则可以配置路由表中的非标卡缺省项指向第二目标SE，然后向非标卡缺省项指向的第二目标SE发送交易指令。
