Description

运营商网络切换方法、装置、设备及计算机存储介质
本申请要求于2022年12月09日提交中国专利局、申请号为202211580849.1、申请名称为“运营商网络切换方法、装置、设备及计算机存储介质”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
本发明涉及通信技术领域，尤其涉及一种运营商网络切换方法、装置、设备及计算机存储介质。
背景技术
用户身份识别模块(subscriber identity module，SIM)卡是全球移动通信***(global system for mobile communications，GSM)的移动用户所持有的身份卡，通过SIM卡可以接入其对应的运营商网络，为终端设备提供网络连接服务。
在使用SIM卡连接其对应的运营商网络时，需要先将SIM卡与终端设备中的无线通讯模块连接，再将SIM卡对应的配置数据下载到无线通讯模块中，以使无线通讯模块连接上该运营商网络，并确定无线通讯模块的运行方式以及无线通讯模块与该运营商网络的交互方式。如果更换了不同网络运营商的SIM卡，为使终端设备能够连接上新的运营商网络进行上网，则需要切换无线通讯模块接入的运营商网络。目前，切换运营商网络的方法通常是，由终端设备从服务器下载与新的运营商网络匹配的配置数据到无线通讯模块中，并重启无线通讯模块，以实现网络运营商的切换。
但是在上述方法中，终端设备从服务器下载与新的运营商网络匹配的配置数据的过程耗时较长，会导致终端设备发生较长时间的网络中断。
发明内容
本申请实施例公开了一种运营商网络切换方法、装置、设备及计算机存储介质，以期在切换运营商网络的过程中，缩短终端设备发生网络中断的时长。
第一方面，本申请实施例提供了一种运营商网络切换方法，应用于包含无线通讯模块的终端设备，上述无线通讯模块包含有第一模块固件和至少两组配置数据，上述第一模块固件支持至少两个运营商网络的准入标准，上述至少两组配置数据中的任意一组配置数据与上述至少两个运营商网络中的一个运营商网络匹配，包括：在检测到上述终端设备的标识信息发生变化的情况下，获取上述终端设备的标识信息，上述标识信息与目标运营商网络对应；在上述目标运营商网络为上述至少两个运营商网络中的任意一个运营商网络的情况下，从上述至少两组配置数据中获取与上述目标运营商网络匹配的第一配置数据；根据上述第一配置数据，连接上述目标运营商网络。
在本申请实施例中，无线通讯模块用于将终端设备接入运营商网络，在检测到上述终端设备的标识信息发生变化的情况下，表示需要切换运营商网络。由于终端设备连接并使用目标运营商网络所需的第一模块固件和第一配置数据均包含在终端设备的无线通讯模块中，在切换到目标运营商网络时，可以在无线通讯模块内部加载第一模块固件和第一配置 数据，以切换无线通讯模块的运行方式和无线通讯模块与目标运营商网络之间的信息交互方式。可理解，在该切换过程中，终端设备无需重新从服务器下载新的配置数据以及重启无线通讯模块，可以避免终端设备因此发生网络中断。
在第一方面一个可能的实施方式中，在上述在检测到上述终端设备的标识信息发生变化的情况下，获取上述终端设备的标识信息之前，上述方法还包括：将上述至少两组配置数据集成在运营商配置数据镜像文件中；上述从上述至少两组配置数据中获取与上述目标运营商网络匹配的第一配置数据包括：从上述运营商配置数据镜像文件中获取与上述目标运营商网络匹配的上述第一配置数据。
在本实施例中，由于相较于其他类型的文件，镜像文件具有方便查找以及支持快速启用的优点，因此将每组配置数据集成在运营商配置数据镜像文件中，可以在从上述至少两组配置数据中获取与目标运营商网络匹配的第一配置数据时，减少查找上述第一配置数据消耗的时间，并可实现快速加载上述第一配置数据以使其生效，实现更方便快捷地将终端设备接入目标运营商网络。
在第一方面一个可能的实施方式中，在上述根据上述第一配置数据，连接上述目标运营商网络之前，上述方法还包括：在检测到上述第一配置数据的版本更新的情况下，获取版本更新后的第二配置数据；上述根据上述第一配置数据，连接上述目标运营商网络包括：根据上述第二配置数据，连接上述目标运营商网络。
在本实施例中，由于配置数据是否适用于与其对应的运营商网络会受到该运营商网络的认证周期的影响，在连接目标运营商网络之前，检测与上述目标运营商网络匹配的第一配置数据是否发生了版本更新，在检测到上述第一配置数据的版本更新的情况下，下载版本更新后的第二配置数据，以连接上述目标运营商网络，以避免更新前的版本与上述目标运营商网络认证周期不匹配导致的网络切换失败。
在第一方面一个可能的实施方式中，上述无线通讯模块设置有第一存储分区，上述第一存储分区存储有上述运营商配置数据镜像文件，在上述获取版本更新后的第二配置数据之前，上述方法还包括：将上述第二配置数据下载至上述第一存储分区中，并覆盖上述运营商配置数据镜像文件中的上述第一配置数据。
在本实施例中，将第二配置数据下载至指定的第一存储分区中，由于第一存储分区与无线通讯模块中的其它分区对应不同的存储空间，可以支持不同分区的数据独立下载或更新，因此在下载第二配置数据时可以避免覆盖或损坏其他分区中的数据。此外，将新版本的第二配置数据覆盖掉旧版本的第一配置数据，可以减少镜像文件中的数据冗余，节省配置数据占用的存储空间。
在第一方面一个可能的实施方式中，在上述获取上述终端设备的标识信息之后，上述方法还包括：在上述目标运营商网络为除上述至少两个运营商网络外的任意一个运营商网络的情况下，获取与上述目标运营商网络匹配的固件组合，上述固件组合包括应用处理核(small application processor，SAP)固件、第二模块固件以及第三配置数据；根据上述SAP固件、上述第二模块固件以及上述第三配置数据，连接上述目标运营商网络。
在本实施例中，SAP是上述无线通讯模块中的应用处理核(或称小型应用处理器)。SAP固件用于支持上述无线通讯模块对应的驱动程序管理和调用上述无线通讯模块的功 能，其中上述驱动程序可以与上述无线通讯模块的操作***进行通信，以使上述操作***可以使用无线通讯模块的功能。
在本实施例中，若上述目标运营商网络不是上述至少两个运营商网络中的其中一个，则表示上述第一模块固件不支持上述目标运营商网络的认证标准，因此需要重新下载支持上述目标运营商网络的固件和配置数据。针对单一模块固件支持目标运营商网络的准入标准和不支持该目标运营商网络的认证标准的两种情况，采用不同的切换方式，两种方式组合工作，满足不同场景下网络运营商的切换。
在第一方面一个可能的实施方式中，上述标识信息包括用户身份识别模块SIM卡的移动国家码(mobile country code，MCC)和移动网络号码(mobile network code，MNC)，在上述获取与上述目标运营商网络匹配的固件组合之前，上述方法还包括：获取第一映射表和第二映射表，上述第一映射表记载有MCC和MNC与运营商的关联关系，上述第二映射表记载有运营商身份标识号(identification，ID)与固件组合的关联关系；上述获取与上述目标运营商网络匹配的固件组合包括：根据上述MCC、上述MNC和上述第一映射表，确定上述目标运营商网络对应的运营商ID；根据上述目标运营商网络对应的运营商ID和上述第二映射表，获取与上述目标运营商网络匹配的上述固件组合。
在本实施例中，在用户切换不同运营商类型的SIM卡之后，通常需要切换运营商网络，由于SIM卡的MCC/MNC(MCC和MNC)可以唯一标识SIM卡所对应的国家和网络运营商(即可以唯一标识一个移动网络提供者)，因此通过MCC/MNC和上述第一映射表可以唯一确定一个运营商网络，然后根据该运营商网络对应的运营商ID和上述第二映射表可以确定与上述目标运营商网络匹配的固件组合的信息，便于实现快速获取上述固件组合。
在第一方面一个可能的实施方式中，上述无线通讯模块设置有第二存储分区，在上述根据上述SAP固件、上述第二模块固件以及上述第三配置数据，连接上述目标运营商网之前，上述方法还包括：将上述SAP固件、上述第二模块固件以及上述第三配置数据下载到上述第二存储分区；重启上述无线通讯模块；上述根据上述SAP固件、上述第二模块固件以及上述第三配置数据，连接上述目标运营商网包括：从上述第二存储分区中加载上述SAP固件、上述第二模块固件以及上述第三配置数据，连接上述目标运营商网络。

本申请提供的运营商网络切换方法涉及通信技术领域，具体可应用于切换不同运营商类型的运营商网络。
在用户更换了不同网络运营商的SIM卡之后，为使终端设备能够通过新的SIM卡连接上新的运营商网络进行上网，则需要切换终端设备的无线通讯模块接入的运营商网络。目前，切换运营商网络的方法通常是，由终端设备从服务器下载与新的运营商网络匹配的配置数据到无线通讯模块中，并重启无线通讯模块使该配置数据生效，使得无线通讯模块能够按照该配置数据与基站交互，为终端设备提供网络连接服务。
但是在上述方法中，终端设备从服务器下载与新的运营商网络匹配的配置数据的过程耗时较长，会导致终端设备发生较长时间的网络中断。
针对以上问题，本申请实施例提供了一种运营商网络切换方法，可以在切换运营商网络的过程中，缩短终端设备发生网络中断的时长。
下面将结合本申请实施例中的附图1对上述运营商网络切换方法进行介绍，请参阅图1，图1是本申请实施例提供的第一种运营商网络切换方法的流程示意图。
如图1所示，上述运营商网络切换方法，应用于包含无线通讯模块的终端设备，上述无线通讯模块包含有第一模块固件和至少两组配置数据，上述第一模块固件支持至少两个运营商网络的准入标准，上述至少两组配置数据中的任意一组配置数据与上述至少两个运营商网络中的一个运营商网络匹配，上述方法包括以下步骤：
S101、在检测到终端设备的标识信息发生变化的情况下，获取上述终端设备的标识信息，上述标识信息与目标运营商网络对应。
可理解的，在上述第一模块固件支持至少两个运营商网络的准入标准情况下，说明该第一模块固件也满足上述至少两个运营商网络的准入认证周期，进一步地，在模块固件满足运营商网络的准入标准和准入认证周期的情况下，该模块固件可以使无线通讯模块运行起来以实现无线通讯模块的基本功能或特定功能。
此外，由于不同运营商的网络标准可能是不同的，因此，每个运营商可以各自对应一组配置数据，以满足各个运营商的网络标准。可理解，若一些运营商的网络标准是相同的，则这些运营商可以对应一组通用配置数据或对应多组相同的配置数据。
在本申请实施例中，上述标识信息可以用来唯一区分运营商网络。示例性的，在终端设备检测到上述标识信息发生变化的情况下，表示当前终端设备需要切换运营商网络，此时可以由终端设备内部的指定的监测程序获取上述标识信息，以确定需要切换的目标运营商网络。
S102、在上述目标运营商网络为至少两个运营商网络中的任意一个运营商网络的情况下，从上述至少两组配置数据中获取与上述目标运营商网络匹配的第一配置数据。
在本申请实施例中，若上述目标运营商网络为至少两个运营商网络中的任意一个运营商网络，则表示上述第一模块固件可以支持上述目标运营商网络的准入标准以及满足上述目标运营商网络的准入认证周期，可以使无线通讯模块运行起来，实现无线通讯模块的基本功能或特定功能。示例性的，由于上述第一模块固件和上述第一配置数据是包含在上述无线通讯模块中的，因此可以实现在无线通讯模块内部加载上述第一配置数据以及使其生效。
S103、根据上述第一配置数据，连接上述目标运营商网络。
在本申请实施例中，示例性的，无线通讯模块可按照上述第一配置数据，确定第一模块固件在无线通讯模块中的运行方式以及无线通讯模块与上述目标运营商的交互方式，连接上述目标运营商网络，然后与基站进行交互。可理解的，在采用本方法切换运营商网络的过程中，终端设备无需重新从服务器下载新的配置数据以及重启无线通讯模块，可以避免终端设备因此发生网络中断，进一步的，可以避免终端设备的操作***界面中的蜂窝(cellular)图标消失的情况，提升用户体验感。
在一些可选的实施方式中，为了实现配置数据的独立下载和更新，还可以在上述无线通讯模块内部的存储***中设置独立的存储分区，以存储上述至少两组配置数据。为了进一步介绍上述运营商网络切换方法，本申请实施例还提供了第二种运营商网络切换方法的 流程示意图，请参阅图2，如图2所示，上述方法包括以下步骤：
S201、将至少两组配置数据集成在运营商配置数据镜像文件中。
应当理解，上述运营商配置数据镜像文件中所包含的配置数据可以与一个或多个运营商匹配。
示例性的，可以在上述无线通讯模块中的存储***中设置第一存储分区，具体的，若上述无线通讯模块包含非易失性存储设备，如NAND闪存(nand flash)，可以在该非易失性存储设备中设置上述第一存储分区，以存储上述运营商配置数据镜像文件。
可理解的，在终端设备执行S202之前，由于上述至少两组配置数据是集成在运营商配置数据镜像文件中的，在后续切换运营商网络过程中可以对上述运营商配置数据镜像文件中存储的配置数据进行访问和更新(如新增、删除、修改)。可以理解的，若无线通讯模块中已经预先设置好包含上述至少两组配置数据的运营商配置数据镜像文件，则在实施本申请时，可以无需执行S201。
在本实施例中由于镜像文件具有方便查找以及支持快速启用的优点，将上述至少两组配置数据集成在运营商配置数据镜像文件中，可以提高配置数据的检索效率，并可实现快速加载对应的配置数据以使其生效，实现更方便快捷地将终端设备接入目标运营商网络。
S202、在检测到上述终端设备的标识信息发生变化的情况下，获取上述终端设备的标识信息，上述标识信息与目标运营商网络对应。
在本实施例中，关于S202的具体实现方式可参考对应于前述实施例中S102中的内容，在此不作赘述。
S203、在上述目标运营商网络为至少两个运营商网络中的任意一个运营商网络的情况下，从上述运营商配置数据镜像文件中获取与上述目标运营商网络匹配的上述第一配置数据。
在本实施例中，若上述目标运营商网络为至少两个运营商网络中的任意一个运营商网络，则表示上述第一模块固件可以支持上述目标运营商网络的准入周期以及可以满足上述目标运营商网络的准入认证标准，可以使无线通讯模块运行起来。示例性的，可先根据上述第一存储分区的内部结构和存储容量，通过特定的操作指令确定上述第一存储分区在上述无线通讯模块的存储***中对应的存储位置，进一步根据上述运营商配置数据镜像文件的文件信息，提取上述第一配置数据。
S204、是否检测到上述第一配置数据的版本更新。
在本实施例中，在执行S203之后，终端设备对上述第一配置数据的版本进行检测，以确定上述第一配置数据是否有更新版本，示例性的，可以通过上述第一配置数据对应的修改时间、数据量大小、版本号等信息确定其是否发生了版本更新。若检测到版本更新，则执行S205，否则执行S207。可理解，由于配置数据是否适用于与其对应的运营商网络还会受到该运营商网络的认证周期的影响，在连接目标运营商网络之前，检测与上述目标运营商网络匹配的第一配置数据是否发生了版本更新，可以避免更新前的版本与上述目标运营商网络认证周期不匹配导致的网络切换失败。
S205、获取版本更新后的第二配置数据。
在本实施例中，在检测到上述第一配置数据发生更新的情况下，下载版本更新后的第 二配置数据到无线通讯模块中，示例性的，可以通过空中下载技术(over the air download technology，OTA)，将上述第二配置数据下载到上述无线通讯模块中的第一存储分区中，并覆盖原本的第一配置数据，以减少上述运营商配置数据镜像文件中的数据冗余，节省配置数据占用的存储空间。
S206、根据上述第二配置数据，连接上述目标运营商网络。
在本实施例中，示例性的，从上述第一存储分区中读取上述第二配置数据，并配合上述第一模块固件连接上述目标运营商网络，与基站进行交互。具体实现方式可对应参考前述实施例中S103中的相关介绍，在此不作赘述。
S207、根据上述第一配置数据，连接上述目标运营商网络。
在本实施例中，在执行S204之后，若没有检测到上述第一配置数据的版本更新，则根据上述第一配置数据，连接上述目标运营商网络，具体实现方式可对应参考前述实施例中S103中的相关介绍，在此不作赘述。
为了更清楚地介绍上述运营商网络切换方法，下面将结合附图3和附图4进行进一步的介绍。
请参阅图3，图3是本申请实施例提供的第一种运营商网络切换方法的应用场景示意图。以终端设备中包含的第五代移动通信技术(5th generation mobile communication technology，5G)无线通讯模块为例，如图3所示，上述无线通讯模块中包括应用处理核SAP和调制解调器核。
在SAP中设置有OTA分区、SAP分区和非易失性随机访问存储器(non-volatile random access memory，NVRAM)***。在OTA分区中划分有OTA_1分区、OTA_2分区和OTA_3分区。其中，相较于其它分区，OTA_1分区为独立的全球运营商配置数据存储分区(可以是前述第一存储分区)，用于存储前述至少两组配置数据，具体的，该至少两组配置数据可以包括全球运营商网络各自对应的配置数据，也可以包括前述通用运营商配置数据。OTA_2分区为客户客制化数据存储分区，用于存储客户客制化数据。OTA_3分区为客户设备客制化数据存储分区，用于存储客户设备客制化数据。上述SAP分区可以用于存储前述SAP固件。上述NVRAM***可支持调制解调器核从SAP中读取配置数据。
在调制解调器核中设置有调制解调器分区，在上述调制解调器分区中存储有模块固件，该模块固件可以是前述实施例中的第一模块固件。
以上述至少两组配置数据集成在上述运营商配置数据镜像文件中的场景为例，在上述运营商配置数据镜像文件中，每组配置数据可对应一个独立的、按照特定数据结构解析的二进制数据文件(如该二进制文件可以是XXX.mcfopota文件，其中XXX可区分不同的)，在切换运营商网络的过程中，在无线通讯模块内部可从上述OTA_1分区中将上述运营商配置数据镜像文件中的第一配置数据加载至上述NVRAM***中，再由调制解调器对应的无线通信协议栈从该NVRAM***中读取上述第一配置数据，并导入模块固件使该第一配置数据生效，然后上述无线通信协议栈可根据该第一配置数据运行，连接上述目标运营商网络，与基站交互，至此实现运营商网络的切换。
下面将基于如图3所示的应用场景，结合本申请实施例提供的第一种运营商网络切换 方法的交互示意图对上述运营商网络切换方法进行详细介绍，请参阅图4，如图4所示，上述运营商网络切换方法包括以下步骤：
S401、SIM卡驱动向MCC/MNC监测应用程序发送新SIM卡接入消息通知。对应的，MCC/MNC监测应用程序接收上述新SIM卡接入消息通知。
在本实施例中，在用户更换SIM卡之后，上述SIM卡驱动可以检测到SIM卡发生更换，并向MCC/MNC监测应用程序发送新SIM卡接入消息通知，该消息通知用于指示当前SIM卡发生更换。
S402、MCC/MNC监测应用程序通过SIM卡的MCC/MNC，从运营商配置数据存储区获取第一配置数据。
在本实施例中，上述运营商配置数据存储区可以是前述OTA_1分区，其中存储有上述至少两组配置数据或存储有包含上述至少两组配置数据的上述运营商配置数据镜像文件。
示例性的，在SIM卡驱动检测到SIM卡发生更换的情况下，可以读取新SIM卡的文件***，从而获取到上述新SIM卡的MCC/MNC，并将其发送给MCC/MNC监测应用程序，可理解，此时该MCC/MNC可在上述新SIM卡接入消息通知之后被发送，也可以与上述新SIM卡接入消息通知一同被发送。对应的，无线通讯模块内部启动的上述MCC/MNC监测应用程序接收该MCC/MNC。或者，在上述MCC/MNC监测应用程序在接收到SIM卡驱动发送的新SIM卡接入消息通知之后，自主监测并获取上述MCC/MNC。然后，上述MCC/MNC监测应用程序再以上述MCC/MNC为索引，从上述运营商配置数据存储区获取上述第一配置数据。
可理解的，在本实施例中，该MCC/MNC可以包含于前述实施例中的标识信息中，对应的，前述实施例中所描述的终端设备的标识信息发生变化就相当于本实施例中的MCC/MNC发生变化。
S403、MCC/MNC监测应用程序向模块无线通信协议栈发送信号，关闭射频。
在本实施例中，由于在与目标运营商网络匹配的第一配置数据生效之前，上述模块无线通信协议栈使用的是与原先的运营商网络匹配的通信标准，因此在连接上述目标运营商网络之前需要使上述模块无线通信协议栈关闭射频，停止信号收发。示例性的，可以通过断开射频信号的控制逻辑，断开射频开关，以关闭射频。
S404、MCC/MNC监测应用程序加载第一配置数据到NVRAM***中。
在本实施例中，在MCC/MNC监测应用程序在模块内部获取到上述第一配置数据之后，将上述第一配置数据加载到上述NVRAM***中，以便于上述模块无线通信协议栈从上述NVRAM***获取上述第一配置数据并使其生效。
S405、MCC/MNC监测应用程序向模块无线通信协议栈发送信号，打开射频。
在本实施例中，示例性的，可以通过连通射频信号的控制逻辑，打开射频。
S406、模块无线通信协议栈从NVRAM***中获取第一配置数据。
S407、模块无线通信协议栈根据第一配置数据运行，与基站交互。
在本实施例中，上述模块无线通信协议栈按照上述第一配置数据中的配置内容，配置上述无线通讯模块中的第一模块固件的运行方式、以及上述无线通讯模块与上述目标运营商网络或基站的信息交互方式。示例性的，假设切换前上述终端设备连接的运营商网络是 运营商网络A，运营商网络A对应的MTU记为M字节，且运营商网络A不支持网际互连协议(internet protocol，IP)多媒体子***(IP multimedia subsystem，IMS)功能。假设上述目标运营商网络是运营商网络B，运营商网络B对应的MTU记为N字节，且运营商网络B支持IMS功能。因此在无线通讯模块工作在运营商网络A上时，通过与其匹配的配置数据可以告知网络上述无线通讯模块支持的MTU为M字节，且此时IMS功能不可启用；在切换到运营商网络B时，通过上述第一配置数据可以告知网络上述无线通讯模块的MTU是N字节，且此时IMS功能可以启用。
可选的，在S404之前，上述终端设备也可以检测上述第一配置数据的版本是否有更新，例如，若有更新，则可通过上述MCC/MNC监测应用程序或上述无线通讯模块中的其它具有下载权限和功能的应用程序，获取版本更新后的第一配置数据(即前述第二配置数据)。可理解，后续上述模块无线通信协议栈会根据该版本更新后的第一配置数据连接目标运营商网络，关于此部分的其它相关的实现方式，可对应参考前述实施例中S204的相关介绍，在此不作赘述。
在一些可选的实施例中，如果由于上述目标运营商网络与其他运营商网络的准入标准和模块固件的准入认证周期不同，导致上述第一模块固件不支持上述目标运营商网络的准入标准时，则可以从终端设备的主机侧下载新的模块固件和相应的配置数据以支持上述目标运营商网络的准入标准，下面将结合附图5至附图7进行具体介绍。
请参阅图5，图5是本申请实施例提供的第二种运营商网络切换方法的应用场景示意图。如图5所示，在主机侧，模块固件包文件夹中包含根据完成运营商认证的模块固件组合成的多运营商的固件包，具体包含不同运营商网络所对应的SAP固件、模块固件、运营商配置数据镜像(对应前述实施例中的至少两组配置数据)，以及客户客制化数据镜像和MCC/MNC与运营商映射表。
其中SAP固件1、模块固件1、运营商配置数据镜像1对应的固件组合与运营商网络1匹配，SAP固件n、模块固件n、运营商配置数据镜像n对应的固件组合与运营商n匹配。可理解，对于同一固件组合而言，其中的SAP固件和模块固件具有对应匹配关系，以避免无线通讯模块因二者不匹配导致的无法启动等问题。客户客制化数据镜像对应用户根据自身需求对上述无线通讯模块的***主体程序的数据进行配置的数据。MCC/MNC与运营商映射表即为公共陆地移动网(public land mobile network，PLMN)与运营商的映射表(对应于第一映射表)，可以支持通过MCC/MNC获取到与SIM卡匹配的运营商ID，以确定SIM卡对应的运营商网络。
基于图5，上述运营商网络切换方法可以包括以下步骤：
S601、在检测到终端设备的标识信息发生变化的情况下，获取上述终端设备的标识信息，上述标识信息与目标运营商网络对应。
在本实施例中，关于S601的具体实现方式，可参考对应于前述实施例中的S101的相关介绍，在此不作赘述。
S602、在上述目标运营商网络为除至少两个运营商网络外的任意一个运营商网络的情况下，获取与上述目标运营商网络匹配的固件组合。
其中，上述固件组合包括应用处理核SAP固件、第二模块固件以及第三配置数据。
可理解的，上述目标运营商网络为除至少两个运营商网络外的任意一个运营商网络，则可以表示上述目标运营商网络与上述至少两个运营商网络对应的准入标准和准入认证周期存在差异，使得上述第一模块固件不支持上述目标运营商网络的准入标准，可理解的，此时需要重新下载新的模块固件和相应的配置数据到上述无线通讯模块中。
可选的，在S602之前，上述方法还可以包括如下步骤：
S6021、获取第一映射表和第二映射表，上述第一映射表记载有MCC和MNC与运营商的关联关系，上述第二映射表记载有运营商ID与固件组合的关联关系。
示例性的，上述MCC和MNC(或称MCC/MNC)可以包含于前述标识信息中。
对应的，S602可以包括：
S6022、根据上述MCC、上述MNC和上述第一映射表，确定上述目标运营商网络对应的运营商ID。
在本实施例中，由于上述MCC和上述MNC合在一起可以唯一标识SIM卡对应的国家和运营商，进一步可以确定SIM卡对应的运营商网络，可以通过上述MCC和上述MNC获取到上述运营商ID。
S6023、根据上述目标运营商网络对应的运营商ID和上述第二映射表，获取与上述目标运营商网络匹配的上述固件组合。
示例性的，上述第一映射表可以记录有上述运营商ID，通过上述运营商ID作为索引，可以从上述第一映射表中确定与上述目标运营商网络对应的固件组合的信息，并基于该固件组合的信息从主机端获取与上述运营商网络匹配的固件组合。
在本实施例中，在用户切换不同运营商类型的SIM卡之后，通常需要切换运营商网络，由于SIM卡的MCC/MNC可以唯一标识SIM卡所对应的国家和网络运营商，因此通过MCC/MNC和上述第一映射表可以唯一确定一个运营商网络，然后根据该运营商网络对应的运营商ID和上述第二映射表可以确定与上述目标运营商网络匹配的固件组合的信息，便于实现快速获取上述固件组合。
S603、根据上述SAP固件、上述第二模块固件以及上述第三配置数据，连接上述目标运营商网络。
示例性的，在S603之前，上述方法可以包括如下步骤：
S6031、将上述SAP固件、上述第二模块固件以及上述第三配置数据下载到上述第二存储分区。
在本实施例中，由于SAP与无线通讯模块之间具有对应匹配关系，在下载新的SAP固件时，为避免无线通讯模块无法启动，也需要下载与该SAP固件匹配的模块固件(即第二模块固件)，举例来说，若在SAP和无线通讯模块之间新增了一个接口，且该接口需由SAP使用，此时若依旧使用不包含该接口的旧模块固件，则无线通讯模块使用新的SAP固件后可能会因当前旧模块固件不包含该接口而产生问题，进一步导致该无线通讯模块无法启动。
示例性的，上述第二存储分区可以是在无线通讯模块内部的存储***中划分的可用存储空间，如上述第二存储分区可以是上述无线通讯模块中的NAND闪存中的存储区域，具 体如，该第二存储分区可以是如图3所示的SAP分区、OTA分区和调制解调器分区。由于上述第二存储分区与上述无线通讯模块中的其他分区对应的存储区域不同，便于实现独立下载或更新数据(该数据可以是SAP固件、第二模块固件和/或第三配置数据)，避免覆盖或损坏其他分区中的数据。
示例性的，新下载的上述第二模块固件以及上述第三配置数据可以覆盖上述第二存储分区中原本存在的模块固件以及配置数据，以节约存储空间，如当前无线通讯模块工作在运营商网络A上，对应的模块固件和配置数据分别为模块固件1和配置数据1，当切换到运营商网络B时，需要把与运营商网络B对应的模块固件2和配置数据2下载到无线通讯模块中，并覆盖掉模块固件1和配置数据1。
S6032、重启上述无线通讯模块。
对应的，S603具体可以包括：
S6033、从上述第二存储分区中加载上述SAP固件、上述第二模块固件以及上述第三配置数据，连接上述目标运营商网络。
在本实施例中，示例性的，在重启上述无线通讯模块之后，上述无线通讯模块可以根据上述第二存储分区的内部结构和存储容量，确定上述SAP固件、上述第二模块固件以及上述第三配置数据在第二存储分区中对应的存储地址并进行读取，以使其生效并连接上述目标运营商网络。本实施例针对单一模块固件支持目标运营商网络的准入标准和不支持该目标运营商网络的认证标准的两种情况，采用不同的切换方式，两种方式组合工作，满足不同场景下网络运营商的切换。
为了更清楚地介绍如图6所示的运营商网络切换方法，本申请实施例还提供了第二种运营商网络切换方法的交互示意图，请参阅图7。
如图7所示，上述终端设备的主机端包括运营商固件存储区、运营商与固件组合映射表(对应于前述第二映射表)、SIM卡信息与运营商映射表(对应于前述第一映射表)和固件下载管理应用程序。
其中，运营商固件存储区中存储有多个运营商的模块固件和相应的配置数据(对应于如图5所示的模块固件包文件夹中的模块固件和配置数据)。上述运营商与固件组合映射表可用于根据运营商ID确定与其对应的固件组合的信息。上述SIM卡信息与运营商映射表可用于根据SIM卡信息(如MCC/MNC)确定与SIM卡对应的运营商信息(如运营商ID)，该可以是前述MCC/MNC与运营商映射表。
上述终端设备的模块端包括移动宽带接口模块(mobile broadband interface model，MBIM)应用、SIM卡驱动和固件分区。其中，上述MBIM固件与主机侧的固件下载管理应用程序之间建立有通信连接。上述固件分区可以包含前述第二存储分区。
上述运营商网络切换方法可以包括以下步骤：
S701、SIM卡驱动向MBIM应用发送新SIM卡接入消息通知。对应的，MBIM应用接收上述新SIM卡接入消息通知。
在本实施例中，在用户更换SIM卡之后，上述SIM卡驱动可以检测到SIM卡发生更换，并向MBIM应用发送新SIM卡接入消息通知，以便于MBIM应用将上述新SIM卡接 入消息通知转发至主机侧。
S702、MBIM应用将上述新SIM卡接入消息通知发送给固件下载管理应用程序。对应的，固件下载管理应用程序接收上述新SIM卡接入消息通知。
在本实施例中，示例性的，在S701中，SIM卡驱动可以在检测到新SIM卡***的情况下，访问上述新SIM卡的文件***，从而获得上述新SIM卡的MCC/MNC，并将该MCC/MNC发送给上述MBIM应用。可选的，上述SIM卡驱动可以在发送上述新SIM卡接入消息通知时携带上述MCC/MNC，同样的，在MBIM应用将上述新SIM卡接入消息通知发送给固件下载管理应用程序时，也可以携带上述MCC/MNC。
S703、固件下载管理应用程序根据MCC/MNC从SIM卡信息与运营商映射表中运营商ID。
在本实施例中，在固件下载管理应用程序接收到上述新SIM卡接入消息通知和上述MCC/MNC之后，可以根据MCC/MNC从SIM卡信息与运营商映射表中进行检索，获取到新SIM卡对应的运营商ID。
S704、固件下载管理应用程序根据运营商ID从运营商与固件组合映射表中获取固件信息。
上述固件信息为与上述目标运营商网络匹配的固件组合的信息。固件下载管理应用程序根据上述运营商ID从运营商与固件组合映射表中进行检索，可获取到上述固件信息。
S705、固件下载管理应用程序根据固件信息从运营商固件存储区获取固件组合。
在本实施例中，上述固件组合包括前述实施例中的SAP固件、第二模块固件和第三配置数据，其中SAP固件、第二模块固件和第三配置数据可以分别是如图5中所示的一个SAP固件、模块固件和运营商配置数据镜像。示例性的，上述固件组合可以是存储在主机侧的，也可以是从与主机建立有通信连接的第三方平台(如服务器)下载得到的。
S706、固件下载管理应用程序下载固件组合到对应的第二存储分区。
示例性的，若该第二存储分区为如图3所示的SAP分区、OTA分区和调制解调器分区，则上述固件组合中所包含的SAP固件、第二模块固件和第三配置数据可分别对应被加载至SAP分区、调制解调器分区和OTA分区。关于后续在无线通讯模块内部加载该固件组合的相关实现方式，可对应参考前述图3中的相关介绍，在此不作赘述。
S707、固件下载管理应用程序重启无线通讯模块。
在本实施例中，示例性的，固件下载管理应用程序可与SIM卡驱动交互，重启无线通讯模块，使上述无线通讯模块内部的SAP固件、第二模块固件以及第三配置数据生效，连接上述目标运营商网络。可理解，本实施例针对单一模块固件支持目标运营商网络的准入标准和不支持该目标运营商网络的认证标准的两种情况，采用不同的切换方式，两种方式组合工作，可以满足不同场景下网络运营商的切换。
