Description

一种具备近距离无线通信功能的移动设备 技术领域
本发明涉及近场通信技术领域，特别涉及一种具有NFC功能的移动设备。
背景技术
近距离无线通信(NFC，Near Field Communication)技术是一种允许在间隔达十厘米的两个设备之间交换数据的无线通信技术。NFC技术使得移动设备既可用作非接触式卡，也可用作读卡器，以提供执行付款、缴费、售票和访问控制应用程序的能力。
目前通常在移动设备中集成NFC芯片，并在移动设备的客户识别模块(SIM，Subscriber Identity Module)卡内存储相应的数据，使得移动设备具备NFC功能。由于集成在移动设备中的NFC芯片仅有两个电源端口，第一电源端口和第二电源端口。第一电源端口在该移动设备开机时可以由该移动设备中的某些能够提供电源的模块供电(如由该移动设备中的调制解调器(modem)供电)，而在移动设备关机后，NFC芯片中内置的电池可以为第一电源端口供电；在该移动设备进行近距离无线通信(即刷卡)时，该移动设备中的NFC芯片触发的一个电平信号会呈现在第二电源端口。
目前支持双客户识别模块(SIM，Subscriber Identity Module)卡、且集成了NFC芯片的移动设备如图1所示，该移动设备中具有两个SIM卡槽，可以在两个SIM卡槽中分别插入不同的SIM卡，并且可以在不同的SIM卡上存储不同的信息，例如，在插在SIM卡槽1中的SIM卡1上存储银行账户信息，在插在SIM卡槽2中的SIM卡2上存储交通卡信息，这样，用户可以根据应用场景选择刷不同的SIM卡，从而对不同的账户进行操作。其中，SIM卡槽1可以连接移动设备中的NFC芯片上的第一电源端口VCC，SIM卡槽2可以连接NFC芯片上的第二电源端口VDD。对于这种具有NFC功能的移动设备，在用户设备插入两个SIM卡时，可以通过任意一个SIM卡来实现NFC刷卡功能；在用户没有插入SIM 卡时，不能实现NFC刷卡功能。图1中还包括开关S，当移动设备开机时，SIM卡槽2由Modem2供电，当移动设备关机时，SIM卡槽2由NFC芯片供电。
由于移动设备中的NFC的应用程序可以在该移动设备的主应用程序处理器上执行，并存储在该移动设备的主非易失性存储器中，因此，这些NFC应用程序容易受到攻击。并且移动设备的主非易失性存储器通常不安全，不能保护存储在其中的数据免于无意删除或有意操纵。针对这一问题，通常的解决方案是在移动设备中以硬件模块的方式嵌入安全元件(SE，Secure Element)，该安全元件具有嵌入式微处理器的防篡改设备。这种以硬件模块的方式嵌入的SE通常被成为嵌入式SE(embedded SE)。目前eSE是与移动设备中的NFC芯片集成在一起。
当集成NFC芯片的移动设备支持双SIM卡、且具有eSE时，移动设备如图2所示，由于NFC芯片仅有两个电源端口，因此，NFC芯片也只能为eSE和其中一个SIM卡槽供电，在图2中，SIM卡槽1连接第一电源端口VCC，eSE连接第二电源端口VDD。这样，用户只能选择对插在SIM卡槽1中的SIM卡1上存储的账户信息进行操作，或者，对eSE上存储的账户信息进行操作。对于这种移动设备，虽然用户在没有插入SIM卡时，可以通过eSE实现NFC刷卡功能，但是，当用户仅插入一个SIM卡，并且，该SIM卡插在SIM卡槽2中时，若移动设备关机，移动设备不能通过插在SIM卡槽2中的SIM实现NFC刷卡功能，也就是说，此时用户只能通过eSE实现NFC刷卡功能。因此，对于这种移动设备，在用户盲插SIM卡时，若移动设备关机，该移动设备可能仅能通过eSE实现NFC刷卡功能。
综上所述，当移动设备集成NFC芯片、且支持双SIM卡，并具有eSE时，若用户盲插SIM卡，则移动设备关机时可能仅能通过eSE实现NFC刷卡功能。
发明内容

所述选择电路，用于在接收到所述第一电平信号时，通过所述选择电路中的选定的输出端供电。
本发明实施例的有益效果包括：

在本发明实施例提供的具备NFC功能的移动设备中，NFC芯片中的第一电源端口可以为多个SIM卡槽中的一个SIM卡槽供电，供电单元可以在NFC芯片的第二电源端口输出的第一电平信号的控制下为eSE和其余SIM卡槽供电，也就是说，即使在移动设备关机的情况下，只要移动设备进行近距离无线通信，那么NFC芯片的第二电源端口就能输出第一电平信号，该第一电平信号就能够触发供电单元为eSE和与该供电单元相连的SIM卡槽供电，这样，即使在移动设备关机的情况下，无论SIM卡插在移动设备的哪个SIM卡槽中，移动设备都可以通过SIM卡或eSE来实现NFC功能。也就是说，如果本发明 实施例提供的具备NFC功能的移动设备中包括两个SIM卡槽，并且，这两个SIM卡槽均插入SIM卡时，那么本发明实施例提供的具备NFC功能的移动设备在关机状态下，依然可以通过eSE和两个SIM卡中的任意一个来实现NFC功能。
而对于图1所示的移动设备，在插入两个SIM卡后，移动设备只能通过两个SIM卡中的任意一个SIM卡来实现NFC功能。对于图2所示的移动设备，在插入两个SIM卡后，移动设备也只能通过SIM卡1和eSE中的任意一个来实现NFC功能。

而在移动设备处于开机状态时，由移动设备中能够提供电源的模块为与供电单元连接的SIM卡槽供电。因此，每个连接所述开关电路的SIM卡槽，由所述供电单元供电或者由所述开关电路连接的一个能够提供电源的模块供电，开关电路连接的不同的能够提供电源的模块为开关电路连接的不同的SIM卡槽供电。
当本发明实施例提供的具备NFC功能的移动设备包括两个SIM卡槽时，本发明实施例提供的具备NFC功能的移动设备如图3所示，开关电路仅包括一个开关S1；SIM卡槽1连接NFC芯片的第一电源端口VCC，当移动设备处于关机状态时，SIM卡槽1由NFC芯片中的电池通过第一电源端口VCC 供电，当移动移动设备处于开机状态时，SIM卡槽1由Modem1通过第一电源端口VCC供电；SIM卡槽2通过开关S1连接供电单元，在移动设备处于关机状态时，SIM卡槽2由供电单元供电，在移动设备处于开机状态时，SIM卡槽2由Modem2供电。同时，供电单元还可以在第二电源端口VDD输出的第一电平信号的控制下为eSE供电。

可选地，本发明实施例提供的具备NFC功能的移动设备，如图4所示，所述供电单元为电源电路，如供电单元为低压差线性稳压器(LDO，Low Dropout Regular)。当电源电路的输出功率足够大时，供电单元可以在NFC芯片的第二电源端口VDD输出的第一电平信号的控制下，同时为eSE和多个SIM卡槽中除连接第一电源端口VCC的SIM卡槽以外的各个SIM卡槽供电。
可选地，本发明实施例提供的具备NFC功能的移动设备，如图5所示，所述供电单元包括选择电路52和控制电路51；
选择电路52第一输入端连接所述NFC芯片中的第二电源端口VDD，选择电路52的第二输入端连接控制电路51，选择电路52的第一输出端连接所述eSE，选择电路52的输出端中除所述第一输出端以外的每个输出端接一个的SIM卡槽，选择电路52的不同输出端连接不同的SIM卡槽；
控制电路51，用于在所述移动设备处于关机状态、且存储待处理账户信息的SIM卡插在所述供电单元连接的SIM卡槽中时，将存储该所述处理账户信息的SIM卡所插的SIM卡槽连接的选择电路52的输出端作为选择电路52中的选定的输出端；并在所述待处理账户信息存储在所述eSE中时，将选择电路52的第一输出端作为选择电路52中的选定的输出端；

其中，选择电路可以为一个选择器开关，选择器开关的一个输入端连接NFC芯片的第二电源端口，控制电路控制该选择器开关中连接NFC芯片的第二电源端口VDD的输入端与该选择器开关中的一个输出端闭合，当选择器开关中与连接NFC芯片的第二电源端口VDD的输入端接通的输出端连接SIM卡槽时，直接采用第二电源端口VDD输出的第一电平信号为选择器开关中与连接NFC芯片的第二电源端口VDD的输入端接通的输出端所连接的SIM卡槽供电；当选择器开关中与连接NFC芯片的第二电源端口VDD的输入端接通的输出端连接eSE时，直接采用第二电源端口输出的第一电平信号为所述eSE供电。
图5以本发明实施例提供的具有NFC功能的移动设备包括两个SIM卡槽为例进行说明。当待处理的账户信息存储在SIM卡槽2中所插的SIM卡时，SIM卡槽2连接的选择电路52的输出端为选择电路52中的选定的输出端；当待处理的账户信息存储在eSE中时，所述eSE连接的选择电路52的输出端，即第一输出端为选择电路52中的选定的输出端。
图3～图5中任一图所示的移动设备中仅给出了NFC芯片、eSE、SIM卡槽1、SIM卡槽2、Modem1和Modem2之间的供电情况，并没有给出它们之间信息交互的情况。当移动设备通过SIM卡槽1中插入的SIM卡实现NFC刷卡功能时，NFC芯片与SIM卡槽1中插入的SIM卡之间有信息交互；当移动设备通过SIM卡槽2中插入的SIM卡实现NFC刷卡功能时，NFC芯片与SIM卡槽2中插入的SIM卡之间有信息交互；当移动设备通过eSE实现NFC刷卡功能时，NFC芯片与eSE之间有信息交互。
