本申请实施例所涉及的更换手机卡的方法，旨在解决目前现有技术中将SIM卡更换为USIM卡过程繁琐、人力成本高的技术问题。通过在系统中部署服务器，通过移动终端与服务器之间进行的非结构化补充数据业务(Unstructured Supplementary Service Data，USSD)流程，用户可以自助完成换卡操作，不需要特意到网络运营商的营业厅人工换卡，简化了换卡步骤，节约了人力成本。
下面以具体地实施例对本申请的技术方案以及本申请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。
图2为本申请实施例提供的更换手机卡的方法的消息交互图。如图2所示，本申请实施例提供的更换手机卡的方法，可以包括：
S101、终端设备通过SIM卡向服务器发送第一USSD消息。
相应的，服务器可以接收终端设备通过SIM卡发送的第一USSD消息。
其中，第一USSD消息可以用于请求获得验证码。
具体的，终端设备支持使用SIM卡和USIM卡。终端设备当前通过SIM卡进行网络通信。当终端设备需要将SIM卡更换为USIM卡时，首先通过SIM卡向服务器发送第一USSD消息，用于请求获得一个验证码。验证码通常在一段时间内有效且唯一。
需要说明的是，本实施例对于第一USSD消息的实现方式不做限定，可以根据需要设置。USSD是一种基于全球移动通信系统(Global System for Mobile Communication，GSM)的交互式数据业务。当在终端设备上输入网络预先制定的数字或者符号时，例如*#等，再通过发送键或者拨号键就可以向网络发送一条USSD指令。网络根据该USSD指令提醒相应的服务。例如，作为一个示例，第一USSD消息可以为*112#。
需要说明的是，本实施例对于第一USSD消息中可以包括的其他信息不做限定，根据需要进行设置。可选的，第一USSD消息还可以包括终端设备用户的身份信息。其中，终端设备用户的身份信息用于唯一区分注册SIM卡的用户。通常，SIM卡在注册激活时需要用户身份信息。其中，本实施例对于终端设备用户的身份信息的实现方式不做限定。可选的，终端设备用户的身份信息可以包括用户的身份证号码，或者还可以包括用户姓名。
需要说明的是，本实施例对于验证码的实现方式不做限定，可以采用现有的任意一种验证码的实现方式。可选的，验证码可以仅为数字，且对于数字的位数不做限定。例如4位、6位等。可选的，验证码可以为字符串，且对于字符串的长度不做限定。可选的，验证码可以为数字和字符的组合。
S102、若服务器确定SIM卡合法，则生成验证码。
具体的，SIM卡合法，是指该SIM卡没有被更换为USIM卡，且终端设备可以通过该SIM卡进行正常的网络通信。
下面通过具体示例对SIM卡是否合法进行示例性说明。
假设SIM卡欠费，则SIM卡非法。假设SIM卡正处于注销流程，则SIM卡非法。假设用户在营业厅已经完成了将SIM卡更换为USIM卡的操作，则该SIM卡非法。
需要说明的是，本实施例对于服务器生成验证码的实现方式不做特别限定，可以采用现有的任意一种生成验证码的算法和方法。
可选的，确定SIM卡合法，可以包括：
根据第一USSD消息获得SIM卡的IMSI。
若SIM卡的IMSI合法且SIM卡没有被更换为USIM卡，则确定SIM卡合法。
具体的，SIM卡中存储有国际移动用户识别码(International Mobile Subscriber Identification Number，IMSI)，SIM卡与IMSI一一对应。在HSS/HLR中存储的用户签约数据以及与SIM卡相关的其他信息(例如是否欠费、是否停止使用、是否已经更换为USIM卡等)，均与SIM卡的IMSI相关联。因此，可以通过确定SIM卡的IMSI是否合法来确定SIM卡是否合法。服务器接收到了第一USSD消息，可以根据第一USSD消息获得SIM卡的IMSI。SIM卡的IMSI合法，是指该IMSI对应的是一个SIM卡而不是USIM卡、且终端设备可以通过该SIM卡进行正常的网络通信。
其中，确定SIM卡的IMSI是否合法以及确定SIM卡是否被更换为USIM卡，可以有多种实现方式。可选的，若服务器已经同步获取到HSS/HLR中存储的用户信息，则服务器可以根据IMSI在用户信息中进行查找，从而确定SIM卡的IMSI是否合法以及确定SIM卡是否被更换为USIM卡。可选的，若服务器没有同步获取到HSS/HLR中存储的用户信息，则服务器可以将IMSI发送给HSS/HLR，以使HSS/HLR根据该IMSI在存储的用户信息中进行查找，获得确认结果，并将确认结果返回给服务器。该确认结果可以指示SIM卡的IMSI是否合法以及确定SIM卡是否被更换为USIM卡。或者，该确认结果可以包括与该IMSI相关联的用户信息，服务器可以根据该确认结果确定SIM卡的IMSI是否合法以及确定SIM卡是否被更换为USIM卡。
可选的，若第一USSD消息还包括终端设备用户的身份信息，则服务器可以根据终端设备用户的身份信息确定SIM卡的IMSI是否合法。
具体的，若服务器已经同步获取到HSS/HLR中存储的用户信息，服务器可以根据IMSI在服务器上存储的用户信息中进行查找，并判断终端设备用户的身份信息与存储的IMSI相关信息是否一致。若一致，则确定SIM卡的IMSI合法。若不一致，则确定SIM卡的IMSI非法。或者，若服务器没有同步获取到HSS/HLR中存储的用户信息，服务器可以将IMSI和终端设备用户的身份信息发送给HSS/HLR，以使HSS/HLR根据该IMSI在存储的用户信息中进行查找，并判断终端设备用户的身份信息与存储的IMSI相关信息是否一致，获得确认结果，并将确认结果返回给服务器。该确认结果可以指示SIM卡的IMSI是否合法。
可见，通过终端设备用户的身份信息确定SIM卡的IMSI是否合法，可以进一步提升确定SIM卡的IMSI是否合法的准确性，从而提升了将SIM卡更换为USIM卡的安全性。
S103、服务器向终端设备发送验证码。
相应的，终端设备通过SIM卡接收服务器返回的验证码。
S104、在将SIM卡更换为USIM卡之后，终端设备通过USIM卡向服务器发送第二USSD消息。
相应的，服务器接收终端设备通过USIM卡发送的第二USSD消息。
其中，第二USSD消息用于请求将SIM卡更换为USIM卡。第二USSD消息可以包括验证码和SIM卡的移动台综合业务数字网号码(Mobile Station Integrated Services Digital Network number，MSISDN)。
具体的，网络运营商会准备一批待更换用的USIM卡，并开户到HSS/HLR中。该USIM卡只能进行位置更新流程和USSD流程。该USIM卡的MSISDN的原始值为预设号段。预设号段是指预留的“非法”号段，“非法”号段与目前各网络运营商可以使用的“正常”号段相对应。“非法”号段仅用于临时的消息处理，以完成USSD消息交互以及位置更新过程中的消息交互。当终端设备需要将SIM卡更换为USIM卡时，在通过SIM卡向服务器发送第一USSD消息并接受到验证码之后，将通过SIM卡通信更换为通过USIM卡通信。通过USIM卡向服务器发送第二USSD消息，用于请求将SIM卡更换为USIM卡。其中，第二USSD消息中包括的验证码，为终端设备接收到的验证码。第二USSD消息中包括的MSISDN，为发送第一USSD消息时的SIM卡的MSISDN。
需要说明的是，本实施例对于第二USSD消息的实现方式不做限定，可以根据需要设置。例如，作为一个示例，第二USSD消息可以为：*113#验证码#MSISDN。假设验证码为88899，MSISDN原始值为23000000000，则第二USSD消息为*113#88899#23000000000。
需要说明的是，本实施例对于第二USSD消息中还可以包括的其他信息不做限定，根据需要进行设置。可选的，第二USSD消息还可以包括终端设备用户的身份信息。
需要说明，本实施例并不限定用户获取USIM卡的方式。例如：SIM卡用户可以凭网络运营商发送的通知信息(例如短信)免费从营业厅或者网络运营商的代理商处获取USIM卡。或者，SIM卡用户可以自费从营业厅或者代理商处购买USIM卡。
需要说明，本实施例并不限定在终端设备上插入USIM卡的时机和方式，可以根据终端类型而有所不同。例如：若终端设备上仅设置了一个卡槽，则在终端设备通过SIM卡向服务器发送第一USSD消息并接收到返回的验证码之后，将SIM卡从卡槽中取出，并将USIM卡插入到卡槽中。若终端设备上设置了多个卡槽，通常为两个，则可以将SIM卡和USIM卡同时插入不同的卡槽中，或者按照上述仅有一个卡槽的场景更换卡。
S105、若服务器根据第一USSD消息确定的SIM卡的MSISDN与第二USSD消息中包含的SIM卡的MSISDN相同、且确定USIM卡合法，则向终端设备发送第一确认消息。
相应的，终端设备可以通过USIM卡接收服务器返回的第一确认消息。
其中，第一确认消息指示了允许将SIM卡更换为USIM卡。
具体的，根据第一USSD消息确定的SIM卡的MSISDN，指示了需要更换为USIM卡的SIM卡。第二USSD消息中包含的SIM卡的MSISDN，也指示了需要更换为USIM卡的SIM卡。如果两次USSD消息指示的SIM卡的MSISDN相同，则可以确定需要更换为USIM卡的SIM卡为同一张SIM卡。在进一步确定USIM卡合法时，允许将SIM卡更换为USIM卡。
需要说明，本实施例对于服务器根据第一USSD消息确定SIM卡的MSISDN的具体实现方式不做限定。例如，可以根据现有的USSD消息流程中携带的相关信息确定。
需要说明的是，本实施例对于第一确认消息的实现方式不做限定，只要符合终端设备与服务器之间的通信协议即可。
可选的，作为第一种实现方式，确定USIM卡合法，可以包括：
根据第二USSD消息获得USIM卡的IMSI。
若USIM卡的IMSI合法、第二USSD消息中包含的验证码与向终端设备发送的验证码相同、且获得的USIM卡的MSISDN为预设号段，则确定USIM卡合法。
具体的，USIM卡中存储有IMSI，USIM卡与IMSI一一对应。在HSS/HLR中存储的用户签约数据以及与USIM卡相关的其他信息(例如该USIM卡是否已经被其他用户正常使用等)，均与USIM卡的IMSI相关联。因此，可以通过USIM卡的IMSI确定USIM卡是否合法。服务器接收到了第二USSD消息，服务器可以根据第二USSD消息确定USIM卡的MSISDN。服务器接收到的验证码与服务器发送给终端设备的验证码可能相同，也可能不同。若USIM卡的IMSI合法、第二USSD消息中包含的验证码与向终端设备发送的验证码相同、且USIM卡的MSISDN为预设号段，则可以确定USIM卡合法。其中，USIM卡的IMSI合法，是指该IMSI对应的是一个USIM卡而不是SIM卡。第二USSD消息中包含的验证码与向终端设备发送的验证码相同，说明服务器发送给终端设备的验证码与接收到的验证码相同。USIM卡的MSISDN为预设号段，说明该USIM卡没有被成功更换过。因此，可以允许终端设备将SIM卡更换为该USIM卡。
需要说明，本实施例对于服务器根据第二USSD消息确定USIM卡的MSISDN的具体实现方式不做限定。例如，可以根据现有的USSD消息流程中携带的相关信息确定。
可选的，作为第二种实现方式，确定USIM卡合法，可以包括：
根据第二USSD消息获得USIM卡的IMSI。
若USIM卡的IMSI合法、第二USSD消息中包含的验证码与向终端设备发送的验证码相同、获得的USIM卡的MSISDN为预设号段、且获得的第一小区标识与第二小区标识相同，则确定USIM卡合法。
其中，第一小区标识为终端设备发送第一USSD消息时接入的小区的小区标识，第二小区标识为终端设备发送第二USSD消息时接入的小区的小区标识。
具体的，如果第一小区标识与第二小区标识相同，说明终端设备连续两次发送USSD消息时位于同一个小区，则极大可能为同一用户通过终端设备正在进行将SIM卡更换为USIM卡的操作。因此，相比于上述第一种实现方式，在本实现方式中，在确定USIM卡是否合法时还参考了终端设备连续两次发送USSD消息的位置信息，进一步提升了确定USIM是否合法的准确性和安全性，从而提升了将SIM卡更换为USIM卡的安全性。
需要说明，本实施例对于服务器获得第一小区标识和第二小区标识的具体实现方式不做限定。例如，终端设备发送USSD消息之前都会进行位置更新流程，可以通过位置更新流程获取第一小区标识和第二小区标识。
可选的，作为第三种实现方式，确定USIM卡合法，可以包括：
根据第二USSD消息获得USIM卡的IMSI。
若USIM卡的IMSI合法、第二USSD消息中包含的验证码与向终端设备发送的验证码相同、获得的USIM卡的MSISDN为预设号段、且获得的第一IMEI与第二IMEI相同，则确定USIM卡合法。
其中，第一IMEI为发送第一USSD消息的终端设备的IMEI，第二IMEI为发送第二USSD 消息的终端设备的IMEI。
具体的，国际移动设备身份码(International Mobile Equipment Identity，IMEI)可以唯一区分不同的终端设备。第一IMEI唯一确定了发送第一USSD消息的终端设备。第二IMEI唯一确定了发送第二USSD消息的终端设备。如果第一IMEI与第二IMEI相同，则极大可能为用户通过同一个终端设备正在进行将SIM卡更换为USIM卡的操作。因此，相比于上述第一种实现方式，在本实现方式中，在确定USIM卡是否合法时还参考了连续两次发送USSD消息的终端设备是否为同一终端设备，进一步提升了确定USIM是否合法的准确性和安全性，从而提升了将SIM卡更换为USIM卡的安全性。
需要说明，本实施例对于服务器获得第一IMEI和第二IMEI的具体实现方式不做限定。例如，终端设备发送USSD消息之前都会进行位置更新流程，可以通过位置更新流程获取第一IMEI和第二IMEI。
可选的，作为第四种实现方式，若第二USSD消息还包括终端设备用户的身份信息，则确定USIM卡合法，可以包括：
根据第二USSD消息获得USIM卡的IMSI。
