【具体实施方式】
请参阅图1，图1是本发明第一实施例的移动终端的示意框图。如图1所示，本发明的移动终端10包括检测模块11、控制模块12以及存储模块13。
其中，检测模块11用于检测SIM卡是否插入移动终端10内。控制模块12用于当检测模块11检测到SIM卡插入移动终端10内时，复制SIM卡的数据以制作一张虚拟SIM卡，并关闭SIM卡与移动终端10的信号通信。存储模块13用于存储虚拟SIM卡的数据。
本实施例中，检测模块11主要是通过移动终端10的电平的高低变化来检测SIM卡是否插入移动终端10内，具体为：当检测模块11检测到移动终端10的电平由高电平变化到低电平时，则判断为SIM卡插入移动终端10内，当检测到电平由低电平变化到高电平时，则判断为SIM卡从移动终端10内拔出。
应理解，本实施例中，当检测模块11检测到电平由高电平变化到低电平时，还可以判断为SIM卡从移动终端10内拔出，当检测到电平由低电平变化到高电平时，对应判断为SIM卡插入移动终端10内。具体判断规则在此不作限制。
本实施例中，控制模块12复制SIM卡的数据以制作一张虚拟SIM卡具体为：控制模块12复制SIM卡内存储器中的数据到移动终端10的存储模块13内，以制作一张数据信息与SIM卡相同的虚拟SIM卡。
本实施例中，控制模块12在复制SIM卡的数据之前进一步初始化SIM卡。具体而言，控制模块12建立移动终端10与SIM卡之间的通信连接，例如，向SIM卡输送电源信号（VSIM）、复位信号（SRST）、数据信号（SDATA）以及时钟信号（SCLK），使得SIM卡能正常使用。
本实施例中，控制模块12关闭SIM卡与移动终端10的信号通信优选为停止向SIM输送电源信号，使得SIM卡无法与移动终端10进行信号通信。因此，当SIM卡从移动终端10内拔出时，不会损坏SIM卡。
进一步的，控制模块12在关闭SIM卡与移动终端10的信号通信之前进一步建立虚拟SIM卡与移动终端10之间的通信连接，使得移动终端10能直接读取虚拟SIM卡内的数据，进而正常工作。
本实施例中，在控制模块12关闭SIM卡与移动终端10的信号通信之后，检测模块11进一步检测是否需要对SIM卡写入数据，例如添加联系人等，当检测模块11检测到需要对SIM卡写入数据时，控制模块12再次初始化SIM卡，并对SIM卡和虚拟SIM卡同时写入数据，以保持SIM卡与虚拟SIM卡内数据信息的一致性。当完成数据的写入后，控制模块12进一步关闭SIM卡与移动终端10之间的信号通信。
在控制模块12关闭SIM卡与移动终端10的信号通信之后，检测模块11还进一步检测SIM卡是否从移动终端10内拔出，并当检测模块11检测到SIM卡从移动终端10内拔出时，控制模块12卸载虚拟SIM卡的数据。
因此，本实施例通过在SIM卡插入移动终端时，复制该SIM卡的数据到移动终端10的存储模块13中，以制作一张虚拟的SIM，然后关闭SIM卡与移动终端10的信号通信，避免SIM卡热拔插所造成的损坏，有效地保护了SIM卡。
请参阅图2，图2是图1所示的移动终端的一种具体实现方式的结构示意图。如图2所示，本发明的移动终端20包括基带芯片21、SIM卡连接器22和存储器23。其中，基带芯片21分别与SIM卡连接器22和存储器23连接。其中，基带芯片21与SIM卡连接器22的具体连接为：基带芯片21的外部中断引脚EINT与SIM卡连接器22的检测引脚DET连接，并且基带芯片21与SIM卡连接器22进一步通过连接线212连接。
本实施例中，SIM卡连接器22用于收容SIM卡，并通过检测引脚DET检测SIM卡是否插入SIM卡连接器22或从SIM卡连接器22内拔出。基带芯片21实现了图1所示的移动终端10中的检测模块11和控制模块12的功能，具体为：基带芯片21的外部中断引脚EINT用于接收SIM卡连接器22的检测引脚DET传输的信号，并根据该信号产生中断信号到基带芯片21。基带芯片21接收到中断信号后通过连接线212对SIM卡进行信号的控制。
具体而言，当SIM插入SIM卡连接器22时，SIM卡连接器22的检测引脚DET检测到电平从高电平变到低电平，并把该电平的变化传输到基带芯片21的外部中断引脚EINT，基带芯片21的外部中断引脚EINT根据电平的变化产生一个中断信号并将其传输到基带芯片21。基带芯片21接收到中断信号后首先通过连接线212初始化SIM卡。具体而言，基带芯片21通过连接线212向SIM卡输送电源信号、复位信号、数据信号以及时钟信号，使得SIM卡能正常使用。SIM卡正常使用后，基带芯片21复制SIM卡的数据到存储器23中，以制作一张虚拟SIM卡。虚拟SIM卡形成之后，基带芯片21进一步建立虚拟SIM卡与移动终端20之间的通信连接，使得移动终端20能直接读取虚拟SIM卡内的数据。然后基带芯片21关闭SIM卡与移动终端20的信号通信。优选为停止向SIM传输电源信号，使得SIM卡无法与移动终端20进行信号通信。因此，当SIM卡从SIM卡连接器22中拔出时，不会损坏SIM卡。
本实施例中，基带芯片21关闭SIM卡与移动终端20的信号通信之后，进一步检测是否需要对SIM卡写入数据，并当检测到需要对SIM卡写入数据时，基带芯片21再次初始化SIM卡，并对SIM卡和虚拟SIM卡写入数据，以保持SIM卡与虚拟SIM卡内数据信息的一致性。当完成数据的写入后，基带芯片21进一步关闭SIM卡与移动终端20之间的信号通信。
其中，基带芯片21关闭SIM卡与移动终端20的信号通信之后，SIM卡连接器22的检测引脚DET还进一步检测SIM卡是否从SIM卡连接器22中拔出，当SIM卡从SIM卡连接器22中拔出时，SIM卡连接器22的检测引脚DET检测到电平由低电平变化到高电平，进而基带芯片21的外部中断引脚EINT产生中断信号，基带芯片21根据该中断信号卸载虚拟SIM卡的数据。由于基带芯片21在SIM卡从SIM卡连接器22中拔出前已经关闭了其与移动终端20之间的信号通信，因此，避免SIM卡热拔插而造成的损坏，有效地保护了SIM卡。
请参阅图3，图3是本发明第二实施例的控制SIM卡热插拔的方法的流程图。如图3所示，本发明的控制SIM卡热插拔的方法包括以下步骤：
步骤S1：检测SIM卡是否插入移动终端内；
在步骤S1中，当检测的结果为否，即检测SIM卡未插入移动终端内时，返回步骤S1，继续进行检测；当检测的结果为是，即检测到SIM卡插入移动终端内时，跳转到步骤S2。
步骤S2：复制SIM卡的数据并存储在移动终端中，以制作一张虚拟SIM卡；
步骤S3：关闭SIM卡与移动终端的信号通信。
因此，通过在复制SIM的数据以制作一张虚拟SIM卡后，关闭SIM卡与移动终端的信号通信，由此能够避免SIM卡热插拔所造成的损坏，有效地保护了SIM卡。
本发明进一步提供第三实施例的控制SIM卡热插拔的方法，其在前述第二实施例的控制SIM卡热插拔的方法的基础上进行详述。如图4所示，本实施例的控制SIM卡热插拔的方法包括以下步骤：
步骤S11：检测SIM卡是否插入移动终端内；
在步骤S11中，当检测的结果为否，即SIM卡未插入移动终端内时，返回步骤S11，继续检测；当检测的结果为是，即检测SIM卡插入移动终端内时，跳转到步骤S12。
步骤S12：初始化SIM卡；
在步骤S12中，初始化SIM卡具体为：建立移动终端与SIM卡之间的通信连接，例如，向SIM卡输送电源信号、复位信号、数据信号以及时钟信号，使得SIM卡能正常使用。
步骤S13：复制SIM卡的数据并存储在移动终端中，以制作一张虚拟SIM卡；
在步骤S13中，具体为：复制SIM卡内存储器中的数据到移动终端的存储模块，以制作一张数据信息与SIM卡相同的虚拟SIM卡。
步骤S14：建立虚拟SIM卡与移动终端之间的通信连接；
步骤S15：关闭SIM卡与移动终端的信号通信；
在步骤S15中，关闭SIM卡与移动终端的信号通信优选为停止向SIM卡输送电源信号，使得SIM卡无法与移动终端进行信号通信。因此，当SIM卡从移动终端中拔出时，不会损坏SIM卡。
步骤S16：检测是否需要对SIM卡写入数据或者SIM卡是否从移动终端拔出；
在步骤S16中，当检测到的结果为否，即不需要对SIM卡写入数据以及SIM卡也未从移动终端拔出时，返回步骤S16，继续检测；当检测到的结果为是时，跳转到步骤S17或者步骤S19。
步骤S17：需要对SIM卡写入数据，初始化SIM卡；
其中，步骤S17的初始化SIM卡的操作与步骤S12的初始化SIM卡的操作相同，在此不在赘述。
步骤S18：对SIM卡和虚拟SIM卡写入数据；
在步骤S18中，完成对SIM卡和虚拟SIM卡写入数据后，返回步骤S15，即再次关闭SIM与移动终端的信号通信。
步骤S19：SIM卡从移动终端拔出，卸载虚拟SIM卡。
综上所述，本发明在检测到SIM卡插入移动终端内时，复制SIM卡的数据并存储在移动终端中，以制作一张虚拟SIM卡，使得移动终端可直接读取虚拟SIM卡的数据。当完成虚拟SIM卡的制作后关闭SIM卡与移动终端的信号通信，因此，本发明能够避免SIM卡热插拔所造成的损坏，进而有效地保护了SIM卡。
