After the subsystem is displayed in the foreground, the user can still view the first SMS message associated with the subsystem received while the subsystem is closed, preventing SMS data loss and allowing the user to view the second SMS message at an appropriate time. Furthermore, the user needs to view the second SMS message through the subsystem, and cannot directly view it through the main system, achieving isolation of SMS messages from different SIM cards, thereby hiding the second SMS message and protecting user privacy.
  • the electronic device may display a fourth interface of the subsystem before displaying the third interface of the first information application of the subsystem.
  • This fourth interface includes a first notification message indicating the existence of a text message for the first SIM card.
  • the electronic device can first display a prompt message so that the user can be informed in a timely manner of receiving SMS messages associated with the subsystem during the subsystem shutdown period, thus enabling timely viewing of the SMS messages.
  • the fourth interface described above is the desktop of the subsystem, and the second operation described above can be the operation of starting the subsystem.
  • the first prompt information described above is the unread mark on the icon of the first information application on the subsystem's desktop.
  • the unread mark includes the number of SMS messages received by the electronic device from the first SIM card associated with the subsystem while the subsystem is not turned on.
  • the aforementioned fourth interface can also be other interfaces of the subsystem, such as the interface displayed when switching to the inactive state. This application does not limit it.
  • the aforementioned first information is carried in the first notification message.
  • the electronic device does not display the notification message for the first SMS (or the notification message corresponding to the first SMS), thereby disabling SMS notifications for the SIM card associated with the parallel space while the parallel space is not enabled. This prevents unnecessary frequent push notifications and avoids interference with the user's use of the electronic device. Furthermore, it also prevents the leakage of SMS messages corresponding to the parallel space, satisfying the user's need to use part of the SIM card for private purposes, thus effectively protecting the user's privacy.
  • the aforementioned first information includes the contact information corresponding to the second number in the contact information within the subsystem.
  • the electronic device can display a notification message from a second SMS message, which does not include the first information from the second number. Based on this, it prevents user privacy leaks and improves the user experience while providing SMS notification reminders.

  • the sender number of the third SMS message is the same as that of the fourth SMS message.
  • the sixth interface of the first information application of the subsystem is displayed.
  • the sixth interface includes the third SMS message associated with the subsystem, but does not include the fourth SMS message associated with the main system. Based on this, normally, SMS records from the same number would be displayed on the same interface.
  • the recipient number of the third SMS message is the number of the first SIM card
  • the recipient number of the fourth SMS message is the number of the second SIM card.
  • the electronic device switches to displaying the interface of the first information application of the subsystem that includes the third SMS message, allowing the user to quickly view the third SMS message. Furthermore, this interface does not include SMS messages received with the second SIM card after association, achieving isolated management of the SIM cards.
  • the electronic device displays the interface of the main system's second information application, which includes the fourth SMS message.
  • a subsystem being inactive indicates that it is neither displayed in the foreground nor running in the background. Specifically, a subsystem being inactive indicates that it has been exited or destroyed.
  • a third notification message from the second SMS message is displayed when the subsystem is active. Based on this, the active subsystem indicates it is in use, allowing the electronic device to send SMS notifications normally.
  • the fourth notification message of the second SMS message is displayed. Based on this, the fact that the subsystem is not enabled and the first hidden function is disabled indicates that the user wants the electronic device to still send SMS notifications to messages associated with the subsystem even when the subsystem is not enabled.

一种信息隐藏方法及电子设备
本申请要求于2024年07月12日提交国家知识产权局、申请号为202410941875.5、发明名称为“一种信息隐藏方法及电子设备”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
本申请涉及终端技术领域，尤其涉及一种信息隐藏方法及电子设备。
背景技术
随着电子设备(如手机)的发展，越来越多手机支持双卡。其中，手机能够使用两张用户标识模块(subscriber identification module，SIM)卡中的任意SIM卡进行短信服务，如接收短信。
然而，由于手机可以使用两张SIM卡中的任意SIM卡进行短信服务，而不同场景下，用户对短信服务的需求不同。因此，亟需一种关于如何使用不同SIM卡进行短信服务的方案，以满足用户在不同场景下对于短信服务的需求，从而提高用户的使用体验。
发明内容
本申请实施例提供一种信息隐藏方法及电子设备，用于在特定场景下，不显示接收到的短信的相关信息，防止用户隐私泄露，满足不同使用场景下的用户需求。
为达到上述目的，本申请采用如下技术方案：
第一方面，提供了一种信息隐藏方法，应用于电子设备，电子设备包括第一SIM卡和第二SIM卡。在显示主系统的第一界面期间，电子设备接收第一号码对第一SIM卡的第一短信。之后，电子设备显示第一号码的第一信息。之后，响应于用户输入的第一操作，将子系统与第一SIM卡关联。在关联之后，在显示主系统的第二界面期间，电子设备接收第二号码对第一SIM卡的第二短信。在子系统处于未开启且第一隐藏功能开启的情况下，不显示第二号码的第一信息。
接收用户输入的第二操作，电子设备显示子系统的第一信息应用的包括第二短信第三界面。
本申请中，在将子系统与第一SIM卡关联之前，在前台运行主系统期间，在接收到第一SIM卡的第一短信，可以正常显示该第一短信的发送方号码，即第一号码的第一信息，实现接收短信的正常提醒。之后，在将子系统与第一SIM卡关联之后，如果在前台运行主系统期间，电子设备接收到第一SIM卡的第二短信。在该子系统处于未开启且第一隐藏功能开启的情况下，表明在子系统处于未开启时，用户希望电子设备隐藏与子系统关联的短信的情况，则电子设备可以不显示第一号码的第一信息，避免第一信息的泄露，有效保护与未开启的子系统关联的用户数据。在前台显示子系统后，用户还可以查看在子系统关闭期间所接收到子系统关联的第一短信，避免短信数据的丢失，使得用户可以在适当时候查看该第二短信。并且用户需要通过子系统查看，而无法直接通过主系统查看第二短信，实现不同SIM卡的短信的隔离，从而实现第二短信的隐藏，保护了用户隐私。
在一种可能的设计方式中，在显示子系统的第一信息应用的第三界面之前，电子设备还可以显示子系统的第四界面。其中，第四界面包括第一提示信息，第一提示信息提示存在对第一SIM卡的短信。
本申请中，在将子系统切换至前台显示后，电子设备可以先显示第一提示信息，以使用户能够及时获知在子系统关闭期间，接收到子系统关联的短信，从而短信的及时查看。
在一种可能的设计方式中，上述第四界面是子系统的桌面，上述第二操作可以是开启子系统的操作。上述第一提示信息为子系统的桌面中的第一信息应用的图标上的未读标记。未读标记包括在子系统处于未开启期间，电子设备接收到的子系统关联的第一SIM卡的短信的数量。
基于此，通过在第一信息应用的图标上显示未读标记，使得用户能够快速获知，在子系统关闭期间，电子设备接收与子系统所关联的短信的数量，从而使得用户能够及时查看相关短信。
可选地，上述第四界面也可以是子系统的其它界面，如切换至未开启状态时所显示的界面。本申请不对其限制。
在一种可能的设计方式中，上述第一信息携带在第一通知消息中。基于此，在子系统处于未开启时且第一隐藏功能开启的情况下，电子设备不显示第一短信的通知消息(或称为第一短信对应的通知消息)，从而实现在平行空间未开启的同时关闭与该平行空间关联的SIM卡对应的短信通知，进而放置不必要的通知消息的频繁推送，防止对用户使用电子设备产生干扰。并且，也可以防止平行空间对应的短信泄露，满足用户想要将部分SIM卡作为隐私的使用需求，从而有效保护了用户的隐私。
在一种可能的设计方式中，上述第一信息包括子系统内的联系人信息中的第二号码对应的联系人信息。
在子系统处于未开启且第一隐藏功能开启的情况下，电子设备可以显示第二短信的通知消息，该通知消息不包括第二号码的第一信息。基于此，实现在短信通知提醒的基础上，防止用户的隐私的泄露，提供用户的使用体验。
其中，可选地，该通知消息可以包括第一图标，第一图标表示存在子系统的新信息。
在一种可能的设计方式中，在将子系统与所述第一SIM卡关联之后，在显示所述主系统的第五界面期间，该第五界面表示主系统的任一界面，在所述子系统处于开启，且前台不可见的情况下，接收对所述第一SIM卡的第三短信，显示第一弹窗，所述第一弹窗包括第一通知消息和第一图标；所述第一通知消息提示存在新信息，所述第一图标表示存在所述子系统的新信息；
在所述子系统处于开启，且前台不可见的情况下，接收对所述第二SIM卡的第四短信，显示第二弹窗，所述第二弹窗包括第二通知消息，所述第二通知消息提示存在信息。
基于此，在前台运行主系统期间，如果接收到子系统关联的第三短信，在子系统处于开启，且前台不可见的情况下，表明子系统在后台运行，则电子设备可以显示第一弹窗，该第一弹窗包括第一通知消息和第一图标，从而提醒用户接收到子系统关联的短信。如果接收到主系统关联的第四短信，在子系统处于开启，且前台不可见的情况下，则电子设备可以显示第二弹窗，该第二弹窗不包括第一图标，实现上述主系统关联的短信的通知。
在一种可能的设计方式中，上述第三短信与所述第四短信的发送方号码相同。在主系统显示上述第一弹窗之后，响应于对第一弹窗的操作，显示子系统的第一信息应用的第六界面，第六界面包括上述与子系统关联的第三短信，而不包括与主系统关联的第四短信。基于此，通常来讲，同一号码的短信记录会显示在同一界面，但在将第一SIM卡与子系统关联后，即使接收到同一号码的短信，如第三短信和第四短信，但该第三短信的接收方号码是第一SIM卡的号码，第四短信的接收方号码是第二SIM卡的号码，因此，需要隔离保存。相应的，在触发第一弹窗后，电子设备切换显示子系统的第一信息应用的包括该第三短信的界面，使得用户能够快速查看第三短信。并且，该界面不包括在关联之后接收到与第二SIM卡的短信，实现SIM卡的隔离管理。
在一种可能的设计方式，在对第二弹窗操作后，电子设备显示主系统的第二信息应用的包括该第四短信的界面。
在一种可能的设计方式中，子系统处于未开启表示子系统未在前台显示，且未在后台运行。具体的，子系统处于未开启表示子系统被退出或被销毁。
在一种可能的设计方式中，在子系统处于开启的情况下，显示第二短信的第三通知消息。基于此，在子系统处于开启的情况下，表明子系统处于使用中，则电子设备可以正常进行短信通知提醒。
在子系统处于未开启，且第一隐藏功能关闭的情况下，显示第二短信的第四通知消息。基于此，在子系统处于未开启，且第一隐藏功能关闭的情况下，表明用户希望在子系统未开启时，电子设备仍可以对与子系统关联的短信进行短信通知，则电子设备可以显示第二短信的第四通知消息，以实现短信通知提醒，使得用户能够及时查看接收到的与子系统关联的短信。
在一种可能的设计方式中，上述第三通知消息包括第一信息。第四通知消息不包括第一信息，从而实现在短信通知提醒的基础上，保护用户隐私。
在一种可能的设计方式中，第三通知消息和第四通知消息均包括预设提示信息，预设提示信息指示第一信息应用的接收到短信。基于此，实现短信通知提醒，并且保护用户隐私。
在一种可能的设计方式中，上述子系统与第一SIM卡的关联是在子系统内进行的。响应于用户在主系统输入开启子系统的操作，开启子系统，以在子系统内将子系统与第一SIM卡关联，提高关联的安全性，以及隐私性。相应的，在显示主系统的第二界面期间，接收第二号码对第一SIM卡的第二短信之前，响应于用户在子系统输入的第四操作，切换显示主系统。
其中，可选地，为了提高安全性，响应于用户在所述主系统输入开启子系统的操作，身份验证成功后开启子系统。
另外，上述子系统与第一SIM卡的关联也可以是在主系统内进行的，提高关联的便捷性。
其中，可选地，上述关联的过程可以包括：
响应于用户输入的操作，显示相应的界面。其中，该界面包括对应第一SIM卡的第一选项，和对应第二SIM卡的第二选项。第一选项用于将子系统与第一SIM卡关联，将主系统与第二SIM卡关联。第二选项用于将子系统与第二SIM卡关联，将主系统与第一SIM卡关联。
其中，上述第一操作是指对对应第一SIM卡的第一选项的操作。
基于此，子系统提供能够关联的界面，用户可以根据关联需求，选择该界面上的第一选项或第二选项，提高关联操作的便捷性，方便用户将平行空间与SIM卡进行关联。
在一种可能的设计方式中，上述开启子系统的操作包括对主系统的桌面上的子系统的图标的操作、手势操作、语音操作、或对主系统的设置应用提供的进入控件的操作，方便用户快速开启子系统。
在一种可能的设计方式中，在将子系统与第一SIM卡关联之后，用户便无法通过主系统设置第一SIM卡是否可用，保证SIM卡隔离的有效性，使得在主系统内，用户仅能够设置该主系统关联的第二SIM卡。接收用户在主系统内输入的操作，显示相应的界面。其中，该界面包括第一SIM卡的信息，和第二SIM卡的信息。第一SIM卡的信息包括提示信息，且不包括第一SIM卡的号码。该提示信息提示第一SIM卡与子系统关联。第二SIM卡的信息包括第二SIM卡的号码。基于此，在将第一SIM卡与子系统关联后，通过主系统查看不到第二SIM卡的号码，保护用户隐私。
该界面包括对应第二SIM卡的第三选项，不包括对应第一SIM卡的第四选项。第三选项用于设置第二SIM卡开启或关闭。第四选项用于设置第一SIM卡开启或关闭。基于此，防止用户获知与子系统关联的第一SIM卡的信息，保护用户隐私。
或者，该界面包括第三选项，和对应第一SIM卡的第五选项，第五选项用于指示第一SIM卡与子系统关联，且第五选项卡不能够用于设置第一SIM卡开启或关闭。
在一种可能的设计方式中，上述第三界面包括第一发送控件和第一SIM卡的短信记录，不包括SIM卡选项控件和第二SIM卡的短信记录。第二短信属于SIM卡的短信记录中的短信。第一发送控件用于触发使用第一SIM卡发送短信。
在将子系统与第一SIM卡关联之前，响应于用户输入的第四操作，电子设备显示主系统中的第二信息应用的第七界面，该第七界面包括SIM卡选项控件和第二发送控件，第一SIM卡的短信记录和第二SIM卡的短信记录，SIM卡选项控件用于触发切换发送短信的SIM卡。
本申请中，在将子系统与第一SIM卡关联之前，由于电子设备包括多张SIM卡，主系统的第二信息应用提供的包括发送控件的第六界面还包括SIM卡选项控件，使得用户需要根据需求选择进行短信服务的SIM卡。之后，在将子系统与第一SIM卡关联之后，子系统的第一信息应用提供包括发送控件的第三界面，该第三界面不再包括SIM卡选项控件，不支持用户选择进行短信服务的SIM卡，使得能够直接使用特定SIM卡进行短信服务，实现SIM卡的隔离，满足用户在子系统，即在平行空间下，使用特定SIM卡进行短信服务的需求，从而满足不同使用场景下的用户需求，进而满足用户的个性化通信需求。并且避免用户在进行短信服务时，还需要选择SIM卡才能使用特定SIM卡进行短信服务，提高进行短信服务的效率。另外，在关联之前，第六界面混合了多张SIM卡的短信记录，而在关联之后，第三界面仅包括与使用的子系统关联的第一SIM卡的短信记录，实现SIM卡的短信记录的隔离，满足用户想要将部分SIM卡作为隐私的使用需求，从而有效保护了用户的隐私。
在一种可能的设计方式中，第一SIM卡的短信记录表示通过第一SIM卡接收、发送的短信。上述第二SIM卡的短信记录表示通过第二SIM卡接收、发送的短信。
在将子系统与第一SIM卡关联之后，第一SIM卡的短信记录保存在第一存储位置，第二SIM卡的短信记录保存在第二存储位置。其中，第二存储位置与第一存储位置不同，实现不同SIM卡的短信记录的隔离保存，从而保证不同系统内的短信记录互不可见，保护用户隐私，实现SIM卡隔离的有效管理，提高用户使用体验。
在一种可能的设计方式中，第一存储位置是电子设备中的短信数据库中的第一数据表，第二存储位置是短信数据库中的第二数据表。第一数据表与第二数据表不同。基于此，通过将不同SIM卡的短信记录存储在同一短信数据库中的不同数据表中，使得电子设备仅需要管理、维护一个数据库，在实现不同SIM卡的短信记录的隔离保存的基础上，提高电子设备管理、维护短信数据库的效率。
或者，第一存储位置是电子设备中的第二短信数据库，第二存储位置是电子设备中的第一短信数据库，第二短信数据库与第一短信数据库不同。基于此，通过将不同SIM卡的短信记录存储在不同短信数据库，使得一个短信数据库仅保存对应SIM卡的短信记录，方便短信记录的管理。
在一种可能的设计方式中，在将子系统与第一SIM卡关联之前，第一SIM卡的短信记录和第二SIM卡的短信记录均保存在第二存储位置。相应的，在将子系统与第一SIM卡关联之后，电子设备可以将第二存储位置中的第一SIM卡的短信记录保存至第一存储位置，实现短信记录的迁移，从而实现不同SIM卡的隔离保存。
或者，在将子系统与第一SIM卡关联之前，第一SIM卡的短信记录和第二SIM卡的短信记录均保存在第三存储位置。第三存储位置与第一存储位置、第二存储位置均不相同。在将子系统与第一SIM卡关联之后，电子设备可以将第三存储位置中的第一SIM卡的短信记录保存至第一存储位置，将第三存储位置中的第二SIM卡的短信记录保存至第二存储位置，实现短信记录的迁移，从而实现不同SIM卡的隔离保存。
在一种可能的设计方式中，上述第三界面包括第一联系人控件，第一联系人控件用于触发显示子系统内的联系人信息。
第七界面包括第二联系人控件，第二联系人控件用于触发显示主系统内的联系人信息。
其中，子系统内的联系人信息与主系统内的联系人信息不同。
基于此，实现子系统内的联系人信息和主系统内的联系人信息相互隔离，使得用户根据需求设置不同系统内的联系人信息。并且在某一系统内，查看不到另一系统内的联系人信息，保证不同系统内的联系人信息互不可见，保护用户隐私。
在一种可能的设计方式中，上述子系统内的联系人信息与主系统内的联系人信息不同包括以下中的至少一种情况：
子系统内的联系人信息包括第一联系人名称，主系统内的联系人信息包括第一联系人名称，且子系统内的第一联系人名称所对应的号码与主系统内的第一联系人名称对应的号码不同。
子系统内的联系人信息包括第一号码，主系统内的联系人信息包括第一号码，且子系统内的第一号码对应的联系人名称与主系统内的第一号码对应的联系人名称不同。
子系统内的联系人信息包括第一联系人信息，且主系统内的联系人信息不包括第一联系人信息。

子系统内的联系人信息包括第二号码，主系统内的联系人信息不包括第二号码。
在一些实施例中，在关联之前，主系统和子系统内的联系人信息也是隔离的。当然，也可以根据需求，设置为不隔离的。在关联之后，主系统和子系统内的联系人信息是隔离的，也就是说，在主系统内存储的联系人信息与在子系统内存储的联系人信息隔离保存。
第二方面，提供了一种电子设备，包括存储器、显示屏和一个或多个处理器。存储器和处理器耦合。存储器用于存储计算机程序代码，计算机程序代码包括计算机指令。显示屏用于显示处理器生成的图像。当处理器执行计算机指令时，使得电子设备执行如上述第一方面中任一项的法。

具体实施方式
为了便于清楚描述本申请实施例的技术方案，本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。本申请实施例中，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。在本申请实施例中，“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。
为了方面理解，下面先对本申请实施例涉及的部分名词进行解释。
主系统，是电子设备的主要操作系统，其负责管理和控制电子设备的资源，如CPU等硬件资源、应用程序(application，APP)等软件资源。其中，主系统可以运行主空间，该主空间是电子设备的主要用户空间。用户可以根据需求在主空间内可以安装、运行应用程序。
子系统，是运行在主系统的应用层的子系统应用，子系统的运行需要依赖于主系统。子系统可以运行一个虚拟用户空间(以下简称“平行空间”)，平行空间是一个相对于主空间独立的虚拟用户空间，能够提高隐私安全。另外，在平行空间内，也可以安装、运行应用程序。平行空间中的应用程序与主空间中的应用程序是相互独立的，平行空间和主空间中的应用程序可以相同，也可以不同。平行空间可以和主空间同时显示(包括如图1A所示的平行空间与主空间分屏显示，或者如图1B所示的平行空间在主空间上悬浮显示)。或者，平行空间和主空间只有一个在前台显示(参考图1C所示的主空间在前台显示)。其中，上述平行空间和主空间分别具有独立的存储空间。如在主空间内，用户无法访问平行空间中的用户数据，在进入平行空间后，才能访问平行空间的用户数据。另外，平行空间可以存储保密性较高的数据。
上述平行空间与主空间同时显示可以在电子设备前台仅显示平行空间期间，响应用户操作实现的。比如，在电子设备前台显示平行空间期间，电子设备可以显示全屏显示控件、分屏显示控件和悬浮窗显示控件。其中，分屏显示控件用于触发平行空间与主空间分屏显示，悬浮窗显示控件用于触发平行空间在主空间上悬浮显示。用户可以根据需求触发分屏显示控件或悬浮窗显示控件，以使电子设备同时显示平行空间与主空间。又比如，在电子设备前台显示平行空间期间，用户可以通过特定手势1触发同时显示平行空间与主空间。
另外，在平行空间与主空间同时显示期间，用户也可以通过全屏显示控件或特定手势2停止显示平行空间或主空间。
需要说明的是，平行空间与主空间分屏显示可以是左右分屏，也可以是上下分屏。在左右分屏情况下，平行空间可以显示在左侧，主空间可以显示在右侧(参见图1A)；或者平行空间可以显示在右侧，主空间可以显示在左侧。在上下分屏的情况下，平行空间可以显示上方或下方，主空间显示在另一方。
上述悬浮显示可以是上述图1B所示的平行空间在主空间上悬浮显示，也可以是主空间悬浮显示在平行空间，本申请不对其限制。
为了提升平行空间内数据的安全等级，在进入平行空间时可以对用户的身份进行验证，因此，可以设置进入平行空间的密码或生物识别特征，比如指纹、人脸等。平行空间的密码可以与主空间的密码不同，也可以与主空间的密码相同；平行空间的生物识别特征可以与主空间的生物识别特征相同，也可以与主空间的生物识别特征不同，在实际应用中可以根据需要进行选择。举例来说，响应于用户对主空间显示的如图1D中(a)所示的平行空间的图标的操作，电子设备显示如图1D中(b)所示的身份验证界面。在身份验证成功后，进入平行空间，显示如图1D中(c)所示的平行空间的桌面。可以理解的是，图1D中(a)所示的通过主空间显示的平行空间的图标仅是进入平行空间的一种可能的方式，还可以通过其它方式进入平行空间，如图1E中的通过手势进入，或通过图1F所示的主空间的设置应用中的平行空间的进入控件进入。另外，如果电子设备未创建有平行空间，用户也可以先在电子设备上创建平行空间，如当用户需要创建平行空间时，用户可以点击如图1G所示的创建界面上的开启控件，电子设备响应创建平行空间。之后，电子设备便可以直接或响应用户的操作进入平行空间。可选地，在创建平行空间后，电子设备的主空间的桌面上才会显示如图1C所示的平行空间的图标。
平行空间使用/开启：本方案中的“平行空间使用/开启”，包括两种情况：(1)电子设备展示平行空间中的界面时，通过预设手势返回主空间。电子设备检测到预设手势后显示主空间的系统桌面，平行空间在后台运行。例如，用户可以将手指从电子设备的显示屏的底部向显示屏的上方滑动(上滑手势)，直到手指位置超过显示屏的中线后抬起，电子设备检测到上滑手势后，返回主空间，显示主空间的桌面。(2)平行空间在前台显示。
平行空间未使用/未开启：平行空间被退出或者被销毁，在本方案中被称为“平行空间未使用/未开启”用户可以通过点击平行空间的桌面上显示的如图1D中(c)所示的退出控件，触发电子设备退出平行空间，进入主空间。其中，退出平行空间即关闭平行空间，停止对平行空间的使用，退出平行空间后平行空间在后台也不会继续运行。
另外，若用户不想再继续使用平行空间，可以将平行空间进行销毁。例如，响应于用户对如图1F所示的销毁平行空间控件的操作，电子设备销毁平行空间。可选地，在平行空间销毁后，主系统的系统桌面中不存在平行空间图标，平行空间内的数据将不再存在。
平行空间的称呼仅用于示例，在实际应用中，平行空间也可以记为平行系统、双子系统应用、双子安全系统、分身系统、第二系统、安全系统等，在本申请的实施例中均以“平行空间”进行说明。另外，本申请的电子设备可以为折叠屏手机或非折叠屏手机等，在此不做限制，为了便于说明，本申请中以折叠屏手机为例进行图示说明。
上面介绍了本申请涉及的部分名词，下面开始介绍本申请的方案。
基于目前电子设备提供的功能，用户可以使用电子设备进行通话、接发短信等相关的活动。目前电子设备能够支持多SIM卡，即多个电话号码都可以拨打和接听语音通话，并且可以通过收发短信和彩信。以双SIM卡为例，目前用户使用双SIM卡均在主空间下，无法区分使用场景，由此给用户的使用带来不便。而在工作、生活等不同的场景下，用户可能希望能够将区分不同SIM的使用场景。
下面以电子设备是折叠屏手机，且支持双SIM为例，介绍电子设备在主空间下使用多张SIM卡进行短信服务的过程。
发送短信：电子设备处于主空间期间，当用户想要向名称被设置为：“小明”的电话号码发送短信(以下简述为向“小明”发送短信)时，用户可以在如图2中(a)所示的短信界面11上的短信内容编辑框12内输入短信内容。另外，该短信界面11上的SIM卡选项控件13显示SIM卡1的图标(可选的，该图标显示有数字1)，表明如果发送短信，电子设备将使用SIM卡1发送短信。
而如果用户想要电子设备使用SIM卡2发送短信，用户可以点击该SIM卡选项控件13。响应于对该SIM卡选项控件13的点击操作，电子设备可以显示如图2中(b)所示的SIM卡选项14，该SIM卡选项14包括对应SIM卡1的选项15和对应SIM卡2的选项16。之后，响应于用户对选项16的操作，电子设备显示如图2中(c)所示的短信界面17，该短信界面17中的SIM卡选项控件13显示SIM卡2的图标(可选的，该图标显示有数字2)。用户可以点击短信界面17上的发送控件18，响应于用户对发送控件18的点击操作，电子设备使用SIM卡2，向小明发送短信1，显示如图2中(d)所示的界面19。该界面19显示有刚发送的短信1的短信内容20以及该短信1对应的SIM卡2的图标。应理解，短信1可以作为该接收方对应的一条短信记录，或者，短信记录不仅包括短信1，还可以包括短信1的其它内容，如发送时间。
另外，上述界面19还包括“小明”对应的历史短信记录，如界面19上的历史短信记录21a，历史短信记录21b以及历史短信记录22。其中，历史短信记录21a表示电子设备通过SIM卡1发送的短信。历史短信记录21b是电子设备通过SIM卡1发送的短信。历史短信记录22是电子设备通过SIM卡2接收的短信。
接收短信：在处于主空间期间，电子设备接收到接收方号码是SIM卡1对应的号码的短信的情况下，显示如图3中(a)所示的短信通知消息30。响应于用户对该短信通知消息30的点击操作，电子设备显示如图3中(b)所示的短信通知消息30对应的短信31，以指示该短信31的接收方号码是SIM卡1对应的号码，也就是电子设备是通过SIM卡1接收到该短信31。
另外，在处于主空间期间，电子设备还可以接收到接收方号码是SIM卡2对应的号码的短信，如上述图3中(b)所示的短信32。
由于电子设备并未有效地对两张SIM卡进行隔离管理，导致无法根据用户使用需求，在特定场景下仅支持使用特定SIM卡进行短信服务。并且，导致同一用户界面(如上述包括小明对应的短信记录的短信界面)混合两张SIM卡的所有短信数据，增加了用户查看不同SIM卡的短信数据的难度，从而造成增加了短信管理的复杂度。另外，也无法满足用户只想某个用户空间仅显示特定SIM卡对应的短信记录，而不显示所有SIM卡对应的短信记录的使用需求，从而造成无法有效保护用户的隐私数据。
因此，针对上述问题，本申请提出一种对电子设备上的多张SIM卡进行隔离管理的方案。电子设备支持用户空间与SIM卡建立对应关系，使得用户可以根据需求指定用户空间进行服务所使用的SIM卡。以短信服务为例，在用户空间(如平行空间)绑定SIM卡后，在处于该平行空间期间，电子设备仅能够使用该平行空间绑定的SIM卡，即平行空间对应的SIM卡进行短信服务，而无法使用平行空间未绑定的SIM卡进行短信服务。并且主空间仅能够使用其对应的SIM卡，即平行空间未绑定的SIM卡进行短信服务，从而有效地对多张SIM卡进行隔离管理，满足用户在不同用户空间下的使用需求或偏好，进而满足用户的个性化通信服务的需求，避免用户在进行短信服务时，还需要选择SIM卡才能使用特定SIM卡进行短信服务，提高进行短信服务的效率。
在接收到平行空间所绑定的SIM卡的短信后，电子设备可以判断是否满足预设条件。该预设条件可以包括平行空间处于未使用状态，或平行空间处于未使用状态且信息隐藏功能开启中的一个或多个。其中，信息隐藏功能表示在平行空间关闭的情况下，不显示平行空间关联的SIM卡所对应的通知消息。
如果满足预设条件，表明平行空间未使用期间，用户不想要在主空间内显示平行空间对应的短信所对应的通知消息，则电子设备可以隐藏该通知消息，避免显示不必要的通知消息，从而实现在平行空间未开启的同时关闭与该平行空间绑定的SIM卡对应的短信通知，防止对用户使用电子设备产生干扰。并且，也可以防止平行空间对应的短信泄露，以及防止他人获知电子设备还存在其它SIM卡，满足用户想要将部分SIM卡作为隐私的使用需求，从而有效保护了用户的隐私。以及，用户无法通过主系统直接查看该短信，实现短信的隐藏。
另外，通过对SIM卡的隔离管理，使得该用户空间仅显示对应的SIM卡所对应的短信数据(即通过该SIM卡接收或发送的短信)，而不显示其不对应的SIM卡所对应的短信数据，方便用户快速查看所需的短信数据，从而降低短信管理的复杂度。以及保证不同用户空间的短信数据互不可见，满足用户想要将部分SIM卡对应的短信数据作为隐私数据的需求，从而有效保护用户的隐私。
其中，上述平行空间绑定SIM卡的过程可以在平行空间内进行。示例性的，平行空间显示如图4中(a)所示的界面40，该界面40能够用于触发将平行空间与SIM卡绑定，从而触发开启SIM卡的隔离功能。该界面40可以包括对应SIM卡1的选项41、对应SIM卡2的选项42、不设置选项43。其中，对应SIM卡1的选项41用于触发将平行空间与SIM卡1绑定，对应SIM卡2的选项42用于触发将平行空间与SIM卡2绑定，不设置选项43用于触发平行空间不与任何SIM卡建立绑定，即关闭了SIM卡的隔离功能。响应于用户对对应SIM卡2的选项42的选择操作，表明用户想要将SIM卡2与平行空间绑定，那么平行空间将其与SIM卡2绑定，显示如图4中(b)所示的界面44。平行空间与SIM卡2绑定后，两者便建立了对应关系。相应的，主空间与SIM卡1绑定，两者也建立了对应关系。其中，上述图4中(b)所示的界面44还包括信息隐藏功能对应的开关控件45，信息隐藏功能(或称为第一隐藏功能)是指平行空间未使用时，对通过平行空间绑定的SIM卡接收到的短信不进行提醒。该开关控件用于设置信息隐藏功能的状态。该图4中(b)所示的信息隐藏功能对应的开关控件45处于关闭状态，则信息隐藏功能的状态是关闭状态。当用户想要开启信息隐藏功能时，用户可以触发信息隐藏功能对应的开关控件，以使该开关控件处于开启状态(参见图4中(c)所示的开关控件45处于开启状态)，相应的，信息隐藏功能的状态也切换至开启状态。其中，关于信息隐藏功能的详细内容可以参考下文图15的相关内容。
在平行空间绑定SIM卡2后，用户在主空间将不能够设置该SIM卡2，也看不到SIM卡2的信息，如号码。比如，在平行空间绑定SIM卡后，主空间内显示的SIM卡管理界面(参见图4中(d)所示的界面46)中的对应SIM卡1的选项47还能够被用于设置SIM卡1的开启或关闭(或是否可用)，对应SIM卡2的选项48不支持设置SIM卡2的开启或关闭，其指示SIM卡2已经与平行空间绑定。当然，图4中(d)所示的界面46中的对应SIM卡2的选项48所显示的“平行空间已绑定”仅是一种示例，对应SIM卡2的选项48也可以直接显示未插卡，隐藏平行空间所绑定的SIM卡2的信息，满足用户不想要他人获知平行空间绑定SIM卡2的使用需求。
可以理解的是，通常来讲，用户可以选择将SIM卡1或SIM卡2与平行空间绑定，也就是说，上述对应SIM卡2的选项41、对应SIM卡2的选项42实际是单选控件。当然，用户也可以选择将SIM卡1和SIM卡2均与平行空间绑定，也就是说，上述对应SIM卡2的选项41、对应SIM卡2的选项42可以是多选控件。
另外，上述通过在平行空间内进行SIM卡的绑定仅是一种示例，平行空间绑定SIM卡的过程可以也可以在平行空间内进行。以及上述通过图4中(a)所提供的界面40进行SIM卡的绑定也仅是一种示例，还可以通过其它方式实现平行空间与SIM卡的绑定，如通过语音指令，本申请不对其限制。
示例性的，本申请实施例中的电子设备可以是手机、平板电脑、桌面型、膝上型、手持计算机、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本，以及可穿戴设备、个人数字助理(personal digital assistant，PDA)、增强现实(augmented reality，AR)\虚拟现实(virtual reality，VR)设备等能够使用多张SIM卡的电子设备。该电子设备的显示屏可以是折叠屏，也可以是非折叠屏，本申请实施例对该电子设备的具体形态不作特殊限制。

电子设备100可以通过音频模块170，扬声器170A，受话器170B，麦克风170C，耳机接口170D，以及应用处理器等实现音频功能。例如音乐播放，录音等。
传感器模块180可以包括压力传感器，陀螺仪传感器，气压传感器，磁传感器，加速度传感器，距离传感器，接近光传感器，指纹传感器，温度传感器，触摸传感器，环境光传感器，骨传导传感器等。
按键190包括开机键，音量键等。马达191可以产生振动提示。指示器192可以是指示灯，可以用于指示充电状态，电量变化，也可以用于指示消息，未接来电，通知等。
SIM卡接口195用于连接SIM卡。SIM卡可以通过插入SIM卡接口195，或从SIM卡接口195拔出，实现和电子设备100的接触和分离。在本方案中，电子设备100可以支持N个SIM卡接口，N为大于或等于的正整数。
示例性的，上述电子设备100的软件系统可以采用分层架构，事件驱动架构，微核架构，微服务架构，或云架构。本发明实施例以分层架构的Android系统为例，示例性说明电子设备100的软件结构。
图5是本发明实施例的电子设备100的软件结构框图。
分层架构将软件分成若干个层，每一层都有清晰的角色和分工。层与层之间通过软件接口通信。在一些实施例中，将Android系统至少可以分为四层，从上至下分别为应用程序层，应用程序框架层，安卓运行时(Android runtime)和系统库，以及内核层。
应用程序层可以包括一系列应用程序包。
如图6所示，应用程序包可以包括主空间中的应用(如信息应用、联系人应用、通话应用、卡隔离监听模块等)，以及平行空间中的应用(如信息应用、联系人应用、通话应用等)。其中，信息应用又可以称为短信应用。另外，主空间和平行空间还可以包括其它应用，如相机，图库等，本申请不对主空间和平行空间所包括的应用做出限制。
其中，卡隔离监听模块用于确定电子设备的SIM卡的隔离状态，如确定用户空间对应的SIM卡。例如，当用户触发上述图2中(b)所示的对应SIM卡2的选项16后，平行空间将其与SIM卡2绑定，并向主空间的卡隔离监听模块发送绑定指令，该绑定指令包括平行空间的标识及其对应的SIM卡2的ID，以使卡隔离监听模块保存平行空间的标识与SIM卡2的ID之间的对应关系。
其中，平行空间的标识可以是平行空间的userid。示例性的，userid可以是预设数值。
其中，可选地，绑定指令还可以包括主空间的标识及其对应的SIM卡1的标识ID，以使卡隔离模块记录主空间的标识与SIM卡1的ID之间的对应关系。
在一些实施例中，上述平行空间所执行的与绑定SIM卡相关的操作可以通过平行空间的设置应用执行的，如该设置应用向主空间的卡隔离监听模块发送绑定指令。
可以理解的是，由于子系统的运行需要依赖于主系统，因此，为了保证运行流畅性，可以将用户空间(如主空间和平行空间)共用的功能模块(如可隔离监听模块)运行在主空间内。当平行空间需要使用可隔离监听模块，可以与主空间通信，以调用可隔离监听模块。
应用程序框架层为应用程序层的应用程序提供应用编程接口(application programming interface，API)和编程框架。应用程序框架层包括一些预先定义的函数。
如图6所示，应用程序框架层可以包括电信(telecom)服务、通知中心、联系人数据库、通讯提供者(telephonyprovider)、短信数据库和用户空间显示模式设置(User space Mode-Setting，UMS)服务。
其中，telecom服务用于实现短信服务，如发送短信、接收短信等。
通知中心用于显示通知消息，如信息应用的通知消息。
联系人数据库1用于存储电子设备的平行空间内的联系人信息。联系人数据库2用于存储电子设备的主空间内的联系人信息。其中，联系人数据库1和联系人数据库2是相互独立的。可选地，联系人数据库1可以位于平行空间内，联系人数据库2可以位于主空间内。或者，该联系人数据库1位于电子设备的特定位置1，联系人数据库2位于特定位置2。该特定位置1允许平行空间访问，不允许主空间访问。该特定位置2运行主空间访问，不运行平行空间访问。
用户空间显示模式设置服务用于管理用户空间，如用户空间的状态。具体的，该用户空间的状态可以是主空间的运行状态(前台运行、后台运行)、平行空间的状态(使用状态、未使用状态)。
通讯提供者用于将短信(如接收到的短信、接收到的短信)存储到短信数据库。短信数据库用于存储电子设备的平行空间内的短信数据(即通过平行空间对应的SIM卡接收、发送的短信)和主空间内的短信数据(即通过主空间对应的SIM卡接收、发送的短信)。
其中，平行空间内的短信数据和主空间内的短信数据是相互独立的。示例性的，平行空间内的短信数据存储在短信数据库中的平行空间对应的数据表(或称为第一数据表)中，主空间内的短信数据存储在短信数据库中的主空间对应的数据表(或称为第二数据表)中。该平行空间对应的数据表与该主空间对应的数据表不同。可选地，短信数据库可以位于电子设备的特定位置3，该特定位置3允许平行空间以及主空间访问。
在一些实施例中，如图6所示，短信数据库可以包括平行空间对应的短信数据库1(或称为第一短信数据库)和主空间对应的短信数据库2(或称为第二短信数据库)。其中，短信数据库1用于存储平行空间内的短信数据，联系人数据库2用于存储主空间内的短信数据。可选地，该短信数据库1可以位于平行空间，短信数据库2可以位于主空间。或者，该短信数据库1位于电子设备的特定位置4，短信数据库2位于特定位置5。该特定位置4允许平行空间访问，不允许主空间访问。该特定位置5运行主空间访问，不运行平行空间访问。
或者该短信数据库1和短信数据库2均可以保存在主空间，本申请不对其保存位置做出限制。
本申请实施例中，通过应用程序层和应用程序框架层实现对不同用户空间对应的SIM卡所对应的短信数据进行隔离。其中，应用程序层隔离与用户存在交互的操作逻辑，简单来说，用户从用户空间显示的内容上仅能够获知该用户空间对应的SIM卡所对应的短信数据。应用程序框架层对不同用户空间对应的SIM卡所对应的短信数据进行隔离存储。
Android Runtime包括核心库和虚拟机。Android runtime负责安卓系统的调度和管理。
核心库包含两部分：一部分是java语言需要调用的功能函数，另一部分是安卓的核心库。
系统库可以包括多个功能模块。例如：表面管理器(surface manager)，媒体库(media libraries)，三维图形处理库(例如：openGL ES)，二维(2D)图形引擎(例如：SGL)等。
内核层是硬件和软件之间的层。内核层至少包含显示驱动，传感器驱动。
上文介绍的电子设备所包括的软件层仅是一种示例，电子设备可以包括其它软件层或者仅包括上述软件层中的一个或多个，本申请不对其限制。同理，上述软件层所包括的内容仅仅是一种示例，如应用程序框架层还可以包括其它模块，如窗口管理器，内容提供器，视图系统，电话管理器，资源管理器等。
本申请提供一种多用户空间下的短信发送方法、短信接收方法以及通知显示方法。电子设备支持多SIM卡，且电子设备的用户空间能够与SIM卡建立对应关系，使得电子设备无论是在该用户空间内发送短信还是接收短信，均只能使用其对应的SIM卡，而无法使用其不对应的SIM卡，从而有效地实现对SIM卡的隔离管理。另外，在SIM卡隔离期间，在接收到短信后，电子设备还可以根据平行空间的使用情况，隐藏短信通知提醒，保护用户隐私，并且能够避免频繁推送不必要的短信通知对用户的干扰，提高用户使用满意度。
下面将以上述电子设备是折叠屏手机，支持双SIM卡为例，结合上述图5，介绍SIM隔离后短信发送方法、短信接收方法以及通知显示方法的可能的实现过程。其中，短信发送方法的实现过程可以参考下文短信发送部分内容，短信接收方法的实现过程可以参考下文短信接收部分内容，通知显示方法的实现过程可以参考下文隐藏短信通知部分。
短信发送：
本申请实施例中，可以通过上述图4所介绍的SIM卡绑定方式，或者其它方式将平行空间与SIM卡(如SIM卡2)进行绑定。在平行空间绑定SIM卡2后，平行空间与SIM卡2建立对应关系，主空间SIM卡1建立对应关系。之后，当用户想要在平行空间内发送短信时，用户可以在平行空间内输入的相关操作，以触发平行空间显示对应短信界面，该短信界面包括发送控件，且不包括SIM卡选项控件，也就是平行空间不支持选择SIM卡1发送短信。之后，当用户在该短信界面编辑短信完成(如输入接收方号码、短信内容等)后，响应于用户对发送控件的点击操作，平行空间直接使用SIM卡2发送短信，满足用户在特定场景下想要仅使用特定SIM卡的使用需求，从而满足用户的个性化通信需求。具体的，短信发送的过程可以包括如图7所示的S601-S622。
S601、接收用户对信息应用1的操作。
S602、响应用户对信息应用1的操作，启动信息应用1，并向主空间的卡隔离监听模块发送请求1。
其中，请求1用于查询卡隔离状态，即SIM卡的隔离状态。也就是查询电子设备是否开启了SIM卡隔离功能，以及在SIM卡隔离功能开启的情况下，平行空间所对应的SIM卡的ID。
示例性的，上述用户对信息应用1的操作可以是用户对平行空间内的桌面上的信息应用1的图标的操作。当然，通过平行空间桌面显示的信息应用1的图标启动信息应用1也仅是一种可能启动信息应用1的方式，还可以通过其它方式启动信息应用1，如响应于用户输入的特定语音指令，平行空间也可以启动信息应用1，或者，平行空间支持负一屏，响应于用户对负一屏显示的信息应用1的图标的点击操作，平行空间启动信息应用1。
举例来说，用户点击如图8中(a)所示的平行空间显示的桌面上的信息应用1的图标50。响应于用户对该图标50的点击操作，信息应用1可以执行启动操作，并向主空间的卡隔离监听模块发送上述请求1，以确定平行空间是否存在对应的SIM卡。这里用户对信息应用1的图标50的操作可以是指用户对信息应用1的操作。
S603、响应于上述请求1，卡隔离监听模块返回信息1，该信息1包括平行空间所对应的SIM卡的ID。其中，平行空间所对应的SIM卡的ID是SIM卡2的ID。
其中，在绑定时如果记录的是平行空间的标识与SIM卡2的卡槽slotid ID之间的对应关系，在步骤603中上述请求1用于获取slotid的取值。在slotid的值是第一数值(如-1)的情况下，表明电子设备未开启SIM卡隔离功能，平行空间可以使用任意SIM卡，即不存在对应的SIM卡。在slotid的值是第二数值(如1)的情况下，表明电子设备开启了SIM卡隔离功能，平行空间与SIM卡1对应，相应的，主空间与SIM卡1对应。在slotid的值是第三数值(如0)的情况下，表明电子设备开启了SIM卡隔离功能，平行空间与SIM卡2对应，相应的，主空间与SIM卡1对应。
上述平行空间可以与一张SIM卡绑定，那么slotid的值是一个数值，如是第一数值，或第二数值。另外，平行空间还可能与多张SIM卡绑定，因此，上述slotid的值包括两个数值，如包括第二数值和第三数值。
需要说明的是，SIM卡的ID也可以是其它类型的ID，如SIM卡的subid或者ICCID等，本申请不对其作出限制。另外，上述平行空间所对应的SIM卡的ID是SIM卡2的ID仅是一种示例，平行空间对应的SIM卡也可以是SIM卡1，或者，是SIM卡1和SIM卡2，本申请不对其做出限制。
S604、在启动完成后，信息应用1显示短信界面1。其中，该短信界面1包括新建短信控件1。
其中，新建短信控件1用于触发显示新建短信界面1，通过该新建短信界面1能够触发发送短信。
承接上述举例，在信息应用1启动完成后，信息应用1可以显示初始短信界面，也就是如图8中(b)所示的短信界面51，该短信界面1包括新建短信控件52。这里短信界面51可以是指S604中的短信界面1，新建短信控件52可以是指S604中的新建短信控件1。
S605、响应于用户对新建短信控件1的点击操作，信息应用1显示新建短信界面1。该新建短信界面1包括短信内容编辑框、发送控件、接收方号码输入框和联系人控件，且该新建短信界面1不显示SIM卡1的信息。
其中，短信内容编辑框用于输入短信内容。发送空间用于触发发送短信。接收方号码输入用于输入接收方号码。联系人控件用于选取收件人，也就是短信接收方。
继续承接上述举例，响应于用户对上述图8中(b)所示的新建短信控件52的点击操作，信息应用1可以显示如图8中(c)所示的新建短信界面53，该新建短信界面1可以包括短信内容编辑框54、发送控件55、接收方号码输入框(即收件人号码输入框)56和联系人控件57，且该新建短信界面53不包括SIM卡选项(如上述图2中(a)所示的SIM卡选项13)，不再显示SIM卡1的信息，使得用户在平行空间内感知不到SIM卡1的存在，实现了SIM卡隔离，保护用户隐私。另外，新建短信界面53也可以包括除短信内容编辑框54、发送控件55、接收方号码输入框(即收件人号码输入框)56和联系人控件57以外的其它内容，本申请不对其限制。其中，图8中(c)所示的新建短信界面53可以是指上述S605中的新建短信界面1。
在一些实施例中，在平行空间存在对应的SIM卡，如上述与SIM卡2对应后，短信发送界面(即能够触发发送短信的界面)可以显示SIM卡2的图标，而不显示SIM卡1的信息，从而不支持用户选择SIM卡1。例如，响应于用户对新建短信控件1的点击操作，信息应用1可以显示如图8中(d)所示的新建短信界面58，该新建短信界面58可以包括SIM卡2的图标59，以使用户获知信息应用1将使用SIM卡2发送短信，避免用户想使用SIM卡1发送短信却使用SIM卡2发送短信的情况的出现。其中，图8中(d)所示的新建短信界面58可以是指上述S605中的新建短信界面1。
在一些实施例中，上述短信界面1可以包括短信列表。短信列表可以包括在SIM卡2与平行空间绑定之后，SIM卡2对应的短信条目，其表示通过SIM卡2接收或发送的短信所对应的短信条目(如图8中(b)所示的小明对应的短信条目60)，而不包括在平行空间与SIM卡2绑定后，主空间对应的SIM卡1所对应的短信，从而用户在平行空间内无法感知主空间对应的SIM卡1所对应的短信，实现SIM卡对应的短信的隔离管理，有效保护用户隐私数据。
另外，在平行空间与SIM卡绑定之前，如果平行空间安装有信息应用1，该信息应用1所显示的短信记录与主空间的信息应用2所显示的短信记录相同，不对不同SIM卡对应的短信进行隔离管理，满足用户不想要电子设备隔离管理SIM卡的使用需求，避免用户想要在一个用户空间内同时使用两张SIM卡进行短信服务，由于对SIM卡的隔离管理，导致用户的使用需求得不到满足的情况的出现。
上面介绍了显示信息应用的新建短信界面的过程，在显示新建短信界面后，可以在该新建短信界面上编辑短信，如编辑短信内容、接收方号码等，下面将继续介绍编辑短信的过程。
S606、接收用户对上述联系人控件的点击操作。
以电子设备前台同时运行主空间和平行空间为例，用户点击如图9中(a)中的左侧部分的所示的新建短信界面61上的联系人控件62。这里联系人控件62可以是指S606中的联系人控件。
S607、响应于对联系人控件的点击操作，信息应用1向平行空间的联系人应用1发送请求2。其中，请求2用于查询平行空间对应的联系人信息。
其中，平行空间对应的联系人信息是指保存在联系人数据库1中的联系人信息，用户在主空间内无法获取到。平行空间对应的联系人信息可以与主空间对应的联系人信息全部相同，或不同，具体不同的相关解释可以参考下文介绍。
上述平行空间对应的联系人信息可以是用户在平行空间内输入的，用户可以对同一联系号码在主空间和平行空间设置不一样的联系人名称。平行空间的联系人信息还可以来自主空间的联系人数据库2，例如在平行空间销毁或退出后，可以将原平行空间的联系人数据保存至主空间的联系人数据库2，在下一次开启平行空间后，将主空间内平行空间的联系人数据迁移到平行空间的联系人数据库1。
S608、联系人应用1响应于请求2，从联系人数据库1中查询平行空间对应的联系人信息。
S609、联系人应用1向信息应用1发送平行空间对应的联系人信息。
S610、信息应用1显示平行空间对应的联系人信息。
本申请实施例中，联系人控件触发信息应用1获取并显示平行空间对应的用户数据中的联系人信息(或描述为平行空间内的联系人信息)，以从该联系人信息中选取接收方(即收件人)。
继续承接上述举例，响应于用户对上述图9中(a)中的联系人控件62的点击操作，信息应用1通过联系人应用1查询平行空间对应的联系人信息，显示如图9中(b)中的左侧部分的所示的平行空间对应的联系人信息列表，其包括名称是“小梅”的联系人信息63、名称是“小明”的联系人信息64和名称是“小王”的联系人信息67。其中，小梅的号码是13XX，小明的号码是15XX，小王的号码是18XX。
另外，图9中(b)中的右侧部分所示的是主空间对应的联系人信息列表，通过与左侧部分所示的平行空间对应的联系人列表对比，主空间与平行空间对应的联系人信息列表可以不同，也就是说，主空间内的联系人信息与平行空间内的联系人信息可以不同。
本申请实施例中，不同用户空间对应的联系人数据库不同，实现对不同用户空间对应的联系人信息进行隔离存储，防止某个用户空间显示的联系人信息包括其它用户空间对应的联系人信息，从而防止其它用户空间对应的联系人信息泄露，有效保护用户隐私。
需要说明的是，主空间与平行空间对应的联系人信息不同可以是全部不同，或者部分不同。全部不同是指，平行空间中的每个联系人信息均与主空间内的联系人信息不同。部分不同是指，对于平行空间内的部分联系人信息，主空间内也存在该联系人信息，但对于平行空间内的另一部分联系人，主空间便不存在该联系人信息。其中，平行空间与主空间内的联系人信息不同可以是，对于同一号码，主空间和平行空间均存储了该号码(即联系人数据库2和联系人数据库1均存储了该号码)，但对应的联系人不同。例如，图9中(b)所示的主空间内的名称是“小李”联系人信息65中的号码是“15XX”，平行空间内的名称是“小明”联系人信息64中的号码也是“15XX”，二者虽然号码相同，但对应联系人名称不同。
平行空间与主空间内的联系人信息不同还可以是，主空间和平行空间均存储了某个联系人名称，但该联系人名称对应的号码不同。比如，如图9中(b)所示，主空间和平行空间均存储了名称是“小梅”的联系人信息，该主空间内的名称是“小梅”的联系人信息66中的号码是“12XX”，而平行空间内的名称是“小梅”的联系人信息63中的的号码是“13XX”。
平行空间与主空间内的联系人信息不同还可以是，对于平行空间内的某一联系人信息，主空间内(即联系人数据库2内)不存在与该联系人信息中的联系人名称或号码相同的联系人信息，如图9中(b)所示的名称是“小王”的联系人信息67，主空间不存在名称是“小王”或号码是“小王的号码，即18XX”的联系人信息。同理，对于主空间(即联系人数据库2)内的某一联系人信息，联系人数据库1内不存在与该联系人信息中的联系人名称或号码相同的联系人信息,。
可以理解的是，上述联系人应用1、信息应用1均属于平行空间，上述联系人数据库1也可以属于平行空间，或者位于电子设备的特定位置1，该特定位置1允许平行空间访问，但不允许主空间访问。上述请求2的发送实际是应用之间的相互调用，简单来说，上述S607-S609可以替换描述为，信息应用1通过调用联系人应用1，从联系人数据库1中查询平行空间内的联系人信息。
S611、信息应用1接收用户对平行空间对应的联系人信息中的联系人1的信息的操作。
继续承接上述举例，响应于用户对如上述图9中(b)所示的名称是“小明”的联系人信息64的选择操作，联系人应用1将该联系人信息64发送至信息应用1。之后，信息应用1可以将“小明”显示在图9中(c)所示的界面68中的接收方号码输入框69内，“小明”便是接收方。
S612、响应于对联系人1的信息的操作，信息应用1在接收方号码输入框内显示该联系人1的名称。
S613、信息应用1在短信内容编辑框内显示用户输入的短信内容。
继续承接上述举例，用户可以在界面68内的短信内容编辑框70内输入短信内容，实现对发送短信的编辑。其中，该界面68还可以包括发送控件71，该发送控件71可以用于触发发送短信。
另外，由于平行空间内存在“小明”对应的短信记录，即小明向SIM卡2对应的号码发送过短信，以及小明接收到SIM卡2对应的号码发送的短信，因此，上述图9中(c)还可以显示有“小明”对应的短信记录。
在一些实施例中，上文S606-S612介绍的通过联系人信息确定接收方的号码仅是确定接收方的一种可能的方式，也可以通过其它方式确定接收方的号码，如直接在接收方号码输入框69内输入接收方的号码。另外，上述通过新建短信控件1(或称为新建信息控件1)触发平行空间显示短信发送界面也仅是一种示例，电子设备还支持其它方式显示短信发送界面。比如，以电子设备同时前台运行主空间和平行空间为例，用户可以点击如图10中(a)中左侧部分平行空间所示的小明对应的短信条目72，响应于该点击操作，信息应用1可以显示如图10中(b)中左侧部分平行空间所示的包括“小明”对应的短信记录的界面73，该界面73包括发送控件74，也可以作为短信发送界面。又比如，以电子设备前台仅运行平行空间为例，平行空间显示如图11中(a)所示的小明对应的通话记录。响应于对通话记录中的信息应用1的图标75的点击操作，平行空间启动信息应用1，显示如图11中(b)所示的包括“小明”对应的短信记录的界面76，该界面76包括发送控件77，可以作为短信发送界面。
在一些实施例中，在平行空间与SIM卡绑定后，当平行空间显示短信记录时，该短信记录可以包括平行空间对应的SIM卡2的图标(如图12所示图标78)，以指示该短信记录中的短信数据是通过电子设备的SIM卡2发送或接收的。另外，由于平行空间仅绑定SIM卡2，对于平行空间来说，电子设备相当于是单卡，因此，该短信记录可以不显示SIM卡2的图标，如上述图9中(c)、图10中(b)或图11中(b)所示，从而在前台仅运行平行空间时，避免他人获知电子设备还存在另一张SIM卡，保护了用户隐私。
在一些实施例中，为了有效实现SIM卡的隔离，电子设备前台仅运行平行空间时，电子设备的状态栏上仅显示平行空间对应的SIM卡所对应的信号强度的图标(参见图11中(b)所示的信号强度的图标79)，从而使用户感知不到主空间对应的SIM卡，保护用户隐私。同理，电子设备前台仅运行主空间时，电子设备的状态栏上仅显示主空空间对应的SIM卡所对应的信号强度的图标，从而使用户感知不到平行空间对应的SIM卡。
电子设备前台同时运行平行空间和主空间时，电子设备显示平行空间的界面部分显示有平行空间对应的SIM卡所对应的信号强度的图标，显示主空间的界面部分显示有主空间对应的SIM卡所对应的信号强度的图标，具体参见图10中(a)或(b)所示。其中，无线网络的图标也可以分别显示在图10中(a)或(b)所示的左侧和右侧。当然，无线网络的图标也可以仅显示在一侧，如上述图9中(a)、(b)或(c)所示的无线网络的图标显示在左侧。
另外，无论电子设备前台仅运行平行空间、仅运行主空间或者同时运行平行空间和主空间，电子设备的状态栏上均可以显示平行空间对应的SIM卡所对应的信号强度的图标以及主空间对应的SIM卡所对应的信号强度的图标，具体参见上述图9中(a)、(b)或(c)所示。通常来讲，使用电子设备一般是机主本人，通过显示两张SIM卡的信号强度的图标，避免机主产生为什么安装有两张SIM卡，却仅显示有一张SIM卡的疑惑，从而防止机主误认为电子设备出现故障。
上面介绍了编辑短信的过程。在短信编辑完成后，电子设备可以发送编辑完成的短信，以实现短信发送服务。下面将继续介绍短信发送的过程。
S614、响应于用户对上述发送控件的点击操作，信息应用1生成短信1，向telecom服务发送指令1。其中，指令1用于触发telecom服务向联系人1发送短信1。
示例性的，指令1可以包括SIM卡2的ID、联系人1的号码以及短信内容。telecom服务在接收到信息应用1发送的指令1后，响应于该指令1，使用SIM卡2向联系人1的号码发送短信1。相应的，安装有联系人1的号码所对应的SIM卡的终端可以接收到短信1，从而实现在平行空间内使用特定SIM卡发送短信的需求。
S615、响应于指令1，telecom服务向联系人1发送短信1。
S616、在发送成功的情况下，telecom服务向信息应用1发送成功响应消息。
S617，响应于发送成功响应消息，信息应用1显示短信界面2，该短信界面2包括短信1。
示例性的，发送成功响应消息是success消息。在接收发送成功响应消息后，信息应用1确定短信1已经发送成功，短信1可以作为新的一条短信记录显示在短信界面2上。
其中，可选地，上述短信界面2还可以包括短信1对应的发送状态，该发送状态指示已发送，表明成功发送短信1。
在一些实施例中，不仅可能出现短信发送成功的情况，还可能出现短信发送失败的情况。在短信1发送失败时，信息应用1可以显示短信界面3，该短信界面3包括短信1以及对应的发送状态，该发送状态指示发送失败。
其中，可选地，在短信1发送失败的情况下，信息应用1还可以获取并显示短信1发送失败的原因，以使用户及时发现并解决问题。
在一些实施例中，在电子设备发送短信1后，信息应用1也可以将短信1保存在短信数据库，从而信息应用1能够从短信数据库中读取短信1，对短信1执行操作，如显示短信1。下面将继续介绍保存短信1的过程。
S618、信息应用1向通讯提供者发送请求3。其中，请求3用于触发保存短信1。
其中，上述请求3可以包括短信1。在短信1发送成功的情况下，信息应用1可以向通讯提供者发送携带有短信1的请求3，以供利用通讯提供者将短信1保存至短信数据库中。
另外，还可能出现短信发送失败的情况。在短信1发送失败的情况下，信息应用1也可以向通讯提供者发送短信1，以供利用通讯提供者将短信1保存至短信数据库中，从而当信息应用1需要从短信数据库读取联系人1的短信记录时，能够读取到所有短信记录。
其中，可选地，上述请求3还可以包括短信1对应的发送状态信息(或称为状态位)，该发送状态信息指示短信1是否发送成功。如发送状态信息可以是0或1，其中，0指示发送成功，1指示发送失败。
S619、通讯提供者响应于请求3，将短信1保存至短信数据库中。
在一些实施例中，通讯提供者可以将短信1保存至短信数据库中，如将短信1对应的短信记录保存至短信数据库中的平行空间对应的数据表(如threads_para_space表)中。另外，通讯提供者可以将主空间发送的短信保存至短信数据库中的主空间对应的数据表(threads数据表)中。
在另一些实施例中，上述短信数据库可以包括平行空间对应的短信数据库1和主空间对应的短信数据库2。通讯提供者可以将平行空间发送的短信1保存至短信数据库1中。相应的，通讯提供者可以将主空间发送的短信保存至短信数据库2中。
其中，可选地，上述请求3包括标记1(tag1)，tag1用于确定短信1对应的用户空间，即短信1所属的用户空间，从而确定是将该短信1保存至平行空间对应的数据表(或短信数据库1)中，还是将其保存至主空间对应的数据表(或短信数据库2)中。下面将介绍两种可能的通讯提供者通过tag1确定短信1所对应的用户空间的实现方式。
在一种可能的实现方式中，可以通过tag1的取值确定将短信1保存至哪个用户空间对应的数据表或短信数据库中。示例性的，在上述请求3携带的tag1是第一字符的情况下，表明上述请求3是平行空间发送的请求，也即表明短信1对应的平行空间，则通讯提供者可以将短信1保存至平行空间对应的数据表或短信数据库1中。
而在上述请求3携带的tag1是第二字符的情况下，表明上述请求3是主空间的请求，也即表明短信1对应的主空间，通讯提供者可以将短信1保存至主空间对应的数据表或短信数据库2中。
其中，tag1以及tag1的取值可以根据需求设置，如tag1是is_para_space，tag1的取值是第一字符(如true)或第二字符(如false)。在is_para_space＝true的情况下，表明短信1对应平行空间。在is_para_space＝false的情况下，表明短信1对应主空间。
在另一种可能的实现方式中，可以通过判断请求3是否携带有tag1来确定短信1所对应的平行空间。示例性的，在上述请求3包括tag1的情况下，通讯提供者可以将短信1保存至平行空间对应的数据表或短信数据库1中。而在上述请求3未包括tag1的情况下，通讯提供者可以将短信1保存至主空间对应的数据表或短信数据库2中。
当然通讯提供者还可以通过其它方式确定短信1对应的用户空间，如上述请求3携带有用户空间的标识。在该用户空间的标识是主空间的标识的情况下，确定短信1对应主空间。在该用户空间的标识是平行空间的标识的情况下，确定短信1对应平行空间。
在一些实施例中，在用户空间与SIM卡不存在对应关系的情况下，可能仍需要保存平行空间对应的短信。示例性的，响应于用户对上述图4中(a)所示的不设置选项43的点击操作，电子设备关闭SIM卡隔离功能，使得平行空间与SIM卡2解绑，从而使得用户空间与SIM卡不存在对应关系。在需要保存短信时，平行空间向通讯提供者发送的用于触发保存短信的请求中也可以存在指示该短信所属的用户空间的标识的内容，如上述tag1，从而触发通讯提供者将该短信保存至该用户空间对应的数据表或短信数据库中。其中，该短信所属的用户空间的标识可以是根据预设规则确定的。比如，该预设规则是指，平行空间在确定该短信的接收方号码属于平行空间对应的联系人的号码时，确定该短信所属的用户空间的标识是平行空间的标识。又比如，该预设规则是指，根据用户空间的优先级确定，如主空间优先级高于平行空间，那么该短信所属的用户空间的标识是主空间的标识。又比如，该预设规则是指，用户空间的标识是默认的，如在平行空间未绑定SIM卡的情况下，默认将短信保存至主空间对应的数据包或短信数据库中。
S620、在保存成功的情况下，通讯提供者向信息应用1返回至保存成功响应消息。
S621、在保存失败的情况下，通讯提供者向信息应用1返回保存失败响应消息。
S622、响应于保存失败响应消息，信息应用1重新向通讯提供者发送上述请求3。
示例性的，上述保存成功响应消息可以是success消息，上述保存失败响应消息可以是fail消息。信息应用1在接收到保存失败响应消息后，可以重新向通讯提供者发送上述请求3，直至成功将短信1保存至短信数据库中。另外，可选地，一般来说，短信保存失败的可能性较小，因此，信息应用1向通讯提供者发送请求2以触发通讯提供者将短信1保存至短信数据库中后，通讯提供者无需返回相应的响应消息，也就是说，上述S619-S621是可选的步骤，从而减少资源的消耗。
可以理解的是，本申请中的步骤的编号并不代表步骤的执行顺序，如上述S606-S612与S613可以是先后执行的，也可以是同时执行的，本申请不对其做出限制。
本申请实施例中，平行空间内的短信记录包括平行空间在与SIM卡2绑定之后，该SIM卡2所对应的短信记录(也就是电子设备使用该SIM卡2接收、发送的短信)，而不包括在平行空间与SIM卡2绑定之后，SIM卡1所对应的短信记录。同理，主空间内的短信记录包括在平行空间与SIM卡2绑定之后，SIM卡1对应的短信记录，而不包括在平行空间与SIM卡2绑定之后，SIM卡2对应的短信记录。
在一些实施例中，在开启SIM卡隔离功能之前，如在平行空间绑定SIM卡2之前，如果平行空间不存在信息应用1(换言之，在绑定SIM卡2后，信息应用1才安装在平行空间内)，或者平行空间虽然安装有信息应用1，但不存在短信记录，那么在绑定SIM卡2之后，平行空间内的短信记录不仅可以包括上述在平行空间与SIM卡2绑定之后，SIM卡2所对应的短信记录，还可以包括在绑定SIM卡2之前，SIM卡2对应的短信记录，实现短信的迁移。比如，上述图11中(b)所示的平行空间内的“08:00”对应的短信记录是在平行空间绑定SIM卡2之前，电子设备通过SIM卡2发送的短信。相应的，主空间内的短信记录可以不再包括在绑定SIM卡2之前，电子设备通过SIM卡2发送、接收的短信，从而实现将SIM卡2对应的短信记录迁移到平行空间，实现短信记录的隔离，避免属于平行空间内的短信记录的泄露。当然，主空间内的短信记录仍可以包括在绑定SIM卡2之前，SIM卡2对应的短信记录，也就是说，不对在关闭SIM卡隔离功能期间，电子设备的短信记录进行迁移。
其中，上述迁移过程可以包括：在平行空间与SIM卡2绑定后，主空间或平行空间可以通过通讯提供者将发送时间或接收时间在绑定时间之前的SIM卡2对应的短信记录，迁移至该平行空间对应的数据表或平行空间对应的短信数据库1，使得主空间不再显示SIM卡2对应的短信记录，而仅显示SIM卡1对应的短信记录，从而有效保护了用户隐私数据。
当然，上述平行空间对应的数据表或平行空间对应的短信数据库1也可以不包括从主空间内迁移的短信记录，而仅包括绑定之后的SIM卡2对应的短信记录，也就是说，绑定之前的短信记录的存储位置不变。
在另一些实施例中，在开启SIM卡隔离功能之前，平行空间安装有信息应用1，且存在短信记录，该短信记录包括SIM卡1对应的短信记录以及SIM卡2对应的短信记录，平行空间内的短信记录与主空间内的短信记录一致，那么在开启SIM卡隔离功能之后，平行空间内的短信记录可以不再包括SIM卡1对应的短信记录。同理，在开启SIM卡隔离功能之后，主空间内的短信记录可以不再包括SIM卡2对应的短信记录。基于此，实现短信记录的隔离。
其中，上述平行空间可以将在开启SIM卡隔离功能之前的SIM卡2对应的短信记录迁移至短信数据库中的平行空间对应的数据表，或者平行空间对应的短信数据库1中，使得在开启SIM卡隔离功能后，平行空间通过平行空间对应的数据表，或者平行空间对应的短信数据库1加载短信记录时，仅加载SIM卡2对应的短信记录。
当然，平行空间或主空间内的在开启SIM卡隔离功能之前的短信记录仍可以不变，避免用户产生为什么短信记录发生变化的疑惑。并且通常来讲，在开启SIM卡隔离功能之前，表明用户不存在隔离使用SIM卡的需求，用户可能想要在某个用户空间同时使用两张SIM卡，查看SIM卡对应的短信记录，因此，在开启SIM卡隔离功能之后，用户空间仍可以显示其未绑定的SIM卡所对应的短信记录。
需要说明的是，在开启SIM卡隔离功能之前，电子设备的短信记录可以均保存在短信数据库中主空间对应的数据表中，或者主空间对应的短信数据库中。还可以保存至短信数据库中的与主空间和平行空间对应的数据表均不同的数据表中，或与主空间和平行空间对应的短信数据库均不同的短信数据库中。
上面以平行空间发送短信为例详细介绍了在前台运行平行空间期间，电子设备使用平行空间对应的SIM卡2发送短信的过程。另外，用户还可能使用主空间的信息应用(即信息应用2)发送短信。相应的，在前台运行主空间期间，电子设备也可以使用主空间对应的SIM卡1发送短信。其中，使用主空间对应的SIM卡1发送短信可以参考上文介绍的平行空间发送短信的过程，此处不再赘述。
本申请实施例中，用户可以根据自身的使用需求或习惯设置用户空间对应的SIM卡，以使电子设备对不同用户空间对应的SIM卡进行隔离管理。当用户在任意用户空间(如用户空间1)内发送短信时，电子设备可以直接使用与该用户空间1对应的SIM卡发送短信，无需用户选择SIM卡，可以有效提高短信发送消息的效率，并且防止用户由于不知道或者忘记选择SIM卡导致短信发送错误的情况的出现，满足用户在特定用户空间下，仅使用特定SIM卡进行短信服务的需求，提高用户使用满意度。另外，还使得用户感知不到与该用户空间1不存在对应关系的SIM卡的短信记录，保护了用户的隐私。
接收短信：
本申请实施例中，主空间可以接收收件人号码(即接收方号码)是电子设备上的任意SIM卡的号码的短信(或简述为接收任意SIM卡的短信)。当主空间接收到SIM卡的短信后，确定该SIM卡对应的用户空间，从而将该SIM卡的短信保存至对应用户空间下，以使对应用户空间显示该短信，而与该SIM卡不存在对应关系的用户空间并不显示该短信，从而实现对SIM卡的隔离管理，满足用户在特定场景下想要仅显示特定SIM卡的短信数据的使用需求，进而有效保护了隐私数据，并且满足用户的个性化通信需求。具体的，短信接收过程可以包括如图13所示的S701-S711。
S701、接收发送方发送的短信2。
S702、telecom服务发送短信2。
其中，短信2包括发送方的号码、接收方的SIM卡的ID(或称为目标SIM卡的ID)和短信内容。
示例性的，telecom服务在接收到外部设备发送的短信2后，可以发送广播消息1，该广播消息1包括短信2。
在一些实施例中，电子设备在接收到短信2后，telecom服务在确定发送方属于骚扰号码的情况下，可以对该短信2进行拦截处理，如将其添加至垃圾短信中。相应的，telecom服务也就无需执行下文所介绍的步骤。
S703、主空间中的信息应用2接收短信2。
示例性的，在telecom服务广播短信2后，注册了telecom服务监听的应用(包括信息应用2)能够接收到该广播消息1，也就是接收到短信2。
在一些实施例中，由于平行空间的运行需要依赖主空间，即使电子设备仅显示了平行空间的界面，未显示主空间的界面，但该主空间仍处于运行状态。换句话来说，在电子设备运行期间，电子设备的主空间一直处于运行状态(前台运行，或后台运行)。因此，电子设备可以通过主空间，如主空间的信息应用2接收任意SIM卡的短信，从而避免由于平行空间未运行导致无法接收短信的情况的出现。
S704、信息应用2向卡隔离监听模块发送请求4。
其中，请求4用于查询卡隔离状态，具体可以参考上述请求1的相关介绍。
S705、卡隔离监听模块响应于上述请求4，向信息应用2返回信息2，信息2包括平行空间对应的SIM卡的ID。
其中，信息2的描述可以参考上述图7介绍内容中的信息1的相关介绍。
S706、信息应用2根据接收方的SIM卡的ID以及平行空间对应的SIM卡的ID，确定短信2所关联的用户空间。
本申请实施例中，在接收方的SIM卡的ID与平行空间对应的SIM卡的ID一致的情况下，信息应用2可以确定短信2是平行空间所对应的SIM卡接收的，短信2与平行空间关联(或替换描述为短信2属于平行空间)。在接收方的SIM卡的ID与平行空间对应的SIM卡的ID不一致的情况下，信息应用2可以确定短信2是主空间所对应的SIM卡接收的，短信2与主空间关联。
在一些实施例中，在电子设备开启了SIM卡隔离功能后，卡隔离监听模块会返回平行空间对应的SIM卡的ID。但电子设备可能未开启SIM卡隔离功能，那么卡隔离监听模块返回的SIM卡的ID不是SIM卡1的ID也不是SIM卡2的ID，而是特定值。相应的，信息应用2在确定SIM卡的ID是特定值的情况下，可以确定未开启SIM卡隔离功能。
其中，可选地，在确定未开启SIM卡隔离功能的情况下，信息应用2可以根据上文介绍的预设规则确定短信2所关联的用户空间。
在一些实施例中，信息应用2还可以通过其它方式确定短信2所关联的用户空间，如在SIM卡与平行空间绑定后，卡隔离监听模块可以直接记录每个用户空间与SIM卡的ID的对应关系。信息应用2可以直接通过卡隔离监听模块查询与短信2的接收方的SIM卡的ID对应的平行空间，从而得到短信2所关联的用户空间，而无需再通过比较接收方的SIM卡的ID与平行空间对应的SIM卡的ID是否一致确定与短信2关联的用户空间。
S707、信息应用2向通讯提供者发送请求5。其中，请求5用于触发将短信2保存至短信数据库中的短信2关联的用户空间所对应的数据表中。
S708、通讯提供者响应于请求5，将短信2保存至短信数据库中的短信2关联的用户空间所对应的数据表中。
在一些实施例中，在保存成功的情况下，通讯提供者向信息应用2返回至保存成功响应消息。在保存失败的情况下，通讯提供者向信息应用2返回保存失败响应消息，以触发信息应用2重新向通讯提供者发送上述请求5。
需要说明的是，上述用户空间对应的数据表仅是用户空间对应的存储位置的一种可能的实现方式，该存储位置也可以是其它位置，如用户空间对应的短信数据库。
其中，信息应用2将短信2保存至短信数据库的过程可以参考上文介绍的信息应用1将短信1保存至短信数据库的过程，此处不再赘述。
在接收到短信2后，如果该短信2与主空间关联，用户可以通过主空间查看该短信2。而如果该短信2与平行空间关联，用户可以通过平行空间查看该短信2。下面将以短信2与平行空间关联为例，介绍短信2的查看过程。
S709、接收对信息应用1的操作。
S710、响应于对信息应用1的操作，启动信息应用1，并从短信数据库中读取平行空间对应的短信，基于平行空间对应的短信，显示短信界面3，短信界面3包括短信列表。在与短信2关联的用户空间是平行空间的情况下，该短信列表包括短信2对应的短信条目。
S711、响应于对短信2对应的短信条目的点击操作，信息应用1显示短信界面4，该短信界面3显示有短信2。
示例性的，在启动期间，信息应用1可以从短信数据库中的平行空间对应的数据表或者平行空间对应的短信数据库1中读取平行空间对应的短信。该短信数据可以包括基于平行空间对应SIM卡接收或发送的短信。之后，信息应用1可以显示由平行空间对应的短信所对应的短信条目组成的短信列表(或替换描述为由平行空间对应的短信组成的短信列表)，从而使用户能够通过该短信列表获知平行空间对应的SIM卡所对应的短信情况。并且，使得用户能够通过选择短信条目查看短信的具体信息，也就是查看短信记录。
以电子设备前台同时运行平行空间和主空间为例，响应于对如图14中(a)中的左侧部分所示的平行空间的桌面上的信息应用1的图标的点击操作，电子设备启动信息应用1。在启动结束后，信息应用1显示如图14中(b)中的左侧部分所示的初始短信界面(即短信界面3)。短信界面3显示有短信列表，该短信列表可以包括平行空间对应的SIM卡2所对应的短信的条目，如包括接收到的短信2对应的短信条目80。之后，当用户想要查看短信2的具体内容时，用户可以点击短信2对应的短信条目80，电子设备显示包括短信2的界面，使得用户查看短信2的具体内容。另外，通过比较图14中(b)中的左侧所示的平行空间显示的短信列表和右侧所示的主空间显示的短信列表，平行空间显示的短信列表包括短信2对应的短信条目80，但主空间显示的短信列表不包括该短信2对应的短信条目80，实现了不同SIM卡对应的短信的隔离，从而当前台仅运行主空间时，用户无法通过主空间查看短信2。
本申请实施例中，电子设备在接收到用户发送的短信2后，可以根据短信2的接收方的SIM卡的ID确定短信2所关联的用户空间，从而将短信2保存至短信2关联的用户空间对应的存储位置，如短信数据库中的该用户空间对应的数据表，或者该用户空间对应的短信数据库，从而使得该用户空间能够显示该短信2，而另一用户空间无法显示该短信2，实现不同SIM卡的接收短信的隔离管理，能够实现隐私数据的保护，从而满足用户在特定场景下仅支持特定SIM卡接收短信的使用需求。
可以理解的是，上述S709-S711的仅是显示平行空间显示短信2的一种可能的过程，还可能通过其它方式显示短信2。比如，短信2的发送方是“小明”，平行空间在显示包括“小明”的短信记录的界面期间，接收到该短信2，且该短信2的接收方号码是平行空间对应的SIM卡的号码，那么平行空间可以直接将该短信2显示在该界面上。另外，短信2也可能关联主空间，用户也可以通过主空间查看短信2，其过程与上述通过平行空间查看短信2的过程类似。
上面介绍发送接收到短信2后，用户查看该短信的过程。在接收到短信2后，电子设备还可以进行短信通知提醒。下面将结合隐藏短信通知部分继续介绍电子设备如何进行短信通知提醒。
隐藏短信通知：
在SIM卡隔离功能开启期间，用户可能希望在平行空间关闭后，电子设备能够不再推送与平行空间相关的短信通知，从而避免频繁的短信通知对用户使用主空间造成干扰，并且避免与平行空间关联的短信泄露，保护用户隐私。基于此，电子设备在确定接收到短信2关联的用户空间后，可以根据该用户空间的使用情况，确定是否显示短信2对应的通知消息，以确定是否进行短信通知提醒。下面将结合图15继续介绍确定是否显示通知消息的过程。
S801、在上述电子设备接收到的短信2与平行空间关联的情况下，信息应用2向卡隔离监听模块发送请求6。其中，请求6用于查询信息隐藏功能的状态。
其中，信息隐藏功能的状态指示是否信息隐藏功能是否开启，其包括开启状态和关闭状态。开启状态表示，在接收到属于平行空间的短信后，若平行空间处于未使用状态，则不进行短信通知提醒。关闭状态表示，在接收到属于平行空间的短信后，无论平行空间是否处于使用状态，可以进行短信通知提醒。其中，信息隐藏功能的状态可以通过上文介绍的通过图4中(b)或(c)所示的信息隐藏功能对应的开关控件45设置。
S802、卡隔离监听模块向信息应用2发送隐藏功能的状态信息。
示例性的，卡隔离监听模块可以向信息应用2返回状态位1，该状态位1指示隐藏功能的状态。如状态位1是0或1。其中，0指示隐藏功能的开启状态。1指示关闭状态。
S803、信息应用2向UMS服务发送请求7。其中，请求7用于查询平行空间的状态。
其中，请求7可以携带平行空间的标识，如userid。平行空间的状态可以包括使用状态(或称为开启状态)以及未使用状态(或称为未开启状态)。
在一些实施例中，用户可以通过如图1D中(c)所示的平行空间显示的退出控件、或者图1F所示的销毁平行空间控件触发关闭平行空间，该平行空间处于未使用状态。而通过其它方式，如上述介绍的上滑手势触发将平行空间切换为后台运行。
S804、UMS服务向卡隔离监听模块发送平行空间的状态信息。
示例性的，UMS服务可以向信息应用2返回状态位2，该状态位2指示平行空间的状态。如状态位2是0或1。其中，0指示平行空间处于使用状态，1指示未使用状态。
S805、信息应用2向平行空间的联系人应用1发送请求8。其中，请求8用于包括短信2的发送方号码。
本申请实施例中，由于短信2(或称为第二短信)与平行空间关联，因此，需要从平行空间中查询短信2的发送方号码的联系人情况，则信息应用2可以向平行空间的联系人应用1发送请求8，以查询发送人是否是平行空间内的联系人。
S806、响应于请求8，联系人应用1从联系人数据库1查询短信2的发送方号码所对应的联系人2的名称。
S807、联系人应用1向信息应用2发送联系人2的名称。
S808、在平行空间处于使用状态的情况下，信息应用2向通知中心发送请求9。
其中，请求9包括短信2和联系人2的名称。示例性的，请求9可以包括短信2的短信内容、联系人2的名称或发送方号码中的一个或多个。
本申请实施例中，在平行空间处于使用状态的情况下，表明用户当前在使用平行空间，因此，无论信息隐藏功能是否开启，均可以正常进行短信通知提醒，则信息应用2可以直接向通知中心发送请求9以触发通知中心生成对应的通知消息，从而能够使得用户及时获知到短信2。
在一些实施例中，联系人数据库1还可能不存在号码是发送方号码的联系人，也就是未查询到发送方号码所对应的联系人2的名称，那么，联系人应用1可以向联系人应用1返回发送方号码(或称为第二号码)或其它内容，如空值，以指示不存在号码是发送方号码的联系人。相应的，上述请求9也不包括联系人2的名称。
S809、响应于该请求9，通知中心显示短信2对应的通知消息。
示例性的，上述通知消息可以包括对象1(如下文图16A所示通知消息90中的图标91或图16B所示的通知消息92中的图标93)，对象1(或称为第一对象)指示通知消息属于平行空间，以使用户可以直观获知平行空间接收到短信2。该对象1可以根据需求设置，可以是图16A或图16B所示的图标(或称为第一图标)，或文字，只需能够指示通知消息属于平行空间即可。
另外，上述通知消息的显示位置也仅是一种示例，其不仅可以显示在当前界面的上方，也可以显示在左侧、右侧或下方，本申请不对其限制。以及通知消息不仅可以显示在界面，还可以显示在状态通知栏上。
在一些实施例中，上述请求9可以携带标记2，以供通知中心根据标记2确定是否生成平行空间的通知消息。可选地，标记2可以是isParallelSpaceNotify。一种情况下，通知中心可以根据请求9是否携带isParallelSpaceNotify来确定是否生成平行空间的通知消息(或描述为与平行空间关联的通知消息)。在请求9携带的isParallelSpaceNotify的情况下，确定生成平行空间的短信通知消息，相应的，上述短信2对应的通知消息可以包括对象1。否则，上述短信2对应的通知消息可以不包括对象1。
另一种情况下，通知中心可以根据请求9携带的isParallelSpaceNotify的取值来确定是否生成平行空间的通知消息。在请求9携带的isParallelSpaceNotify的取值是true的情况下，确定生成平行空间的短信通知消息，相应的，上述短信2对应的通知消息可以包括对象1。否则，上述短信2对应的通知消息可以不包括对象1。
或者，上述标记2可以是用户空间的标识。短信2与平行空间关联，则请求9携带平行空间的标识。
在一些实施例中，为了保护隐私，通知消息可以不包括短信2的具体内容，如上述图16A所示的通知消息90。另外，通知消息也可以包括短信2的具体内容以及联系人2的名称，如图16B所示的通知消息92，以使用户快速获知短信2的情况。总而言之，通知消息可以包括短信2的短信内容、联系人2的名称、发送方的号码中的一个或多个，或者，通知消息可以仅包括预设提示信息(如上述图16A所示的通知消息中的“1个通知”)。
在一些实施例中，上述通知消息也可以不包括上述对象1。如在平行空间处于使用状态的情况下，短信2对应的通知消息也可以不包括该对象1。
S810、在平行空间处于未使用状态，且信息隐藏功能处于开启状态的情况下，联系人应用1不向通知中心发送请求9。
本申请实施例中，在平行空间的状态是未使用状态，且信息隐藏功能的状态是开启状态的情况下，表明电子设备前台运行主空间期间，如果有发送给平行空间绑定的SIM卡的短信，电子设备可以不进行短信通知提醒，避免平行空间所绑定的SIM卡对应的短信通知对用户正常使用电子设备的干扰，并且防止用户隐私泄露的情况，保护用户隐私。具体的，在前台显示主空间期间，电子设备接收到与平行空间绑定的SIM卡2的短信2，电子设备不显示该短信2对应的通知消息，使得用户在使用主空间期间，并不知道电子设备接收到SIM卡2的短信2，避免短信2对用户的使用造成干扰，并且防止短信2的内容泄露，实现SIM卡的隔离管理。
另外，接收到的短信被保存至平行空间内，使得用户可以根据需求在适当的时候查看，避免短信2的丢失。具体的，当从前台显示主空间切换至平行空间后，用户可以通过平行空间中的信息应用2查看接收到的短信2。
在一些实施例中，在平行空间处于未使用状态，且信息隐藏功能处于开启状态的情况下，联系人应用1仍可以向通知中心发送请求9，以触发通知中心显示短信2对应的通知消息，只不过该通知消息可以仅包括预设提示信息，或者该通知消息可以不包括第一信息，如上述联系人2的名称等。具体内容可以参考下文介绍的平行空间处于未使用状态，且信息隐藏功能处于关闭状态的情况下，显示通知消息的过程。
在一些实施例中，在平行空间处于未使用状态的情况下，电子设备可以直接隐藏短信2对应的通知消息，而无需考虑信息隐藏功能是否开启。或者，显示的通知消息可以仅包括预设提示信息，或者该通知消息可以不包括上述联系人2的名称等。
S811、在平行空间处于未使用状态，且信息隐藏功能处于关闭状态的情况下，信息应用2向通知中心发送请求9。其中，请求9包括短信2。
示例性的，S811中的请求9可以包括短信2的短信内容和/或发送方号码。
本申请实施例中，在平行空间处于未使用状态，且信息隐藏功能处于关闭状态的情况下，表明在电子设备前台运行主空间期间，如果有发送给平行空间绑定的SIM卡的短信，用户仍想要电子设备显示平行空间所绑定的SIM卡接收的短信情况，则电子设备可以继续进行短信通知提醒，以使用户能够及时获知短信接收情况，满足用户不同的使用需求。但为了保护用户隐私，信息应用不向通知中心发送平行空间绑定的SIM卡接收的短信(如上述短信2)的发送方对应的联系人情况。
可以理解的是，平行空间未使用时，即平行空间不在前后台运行时，主空间也无法查询平行空间中的数据，如上述联系人数据。相应的，主空间也无需向通知中心发送短信2的发送方对应的联系人情况。由于信息应用2无需向通知中心发送短信2的发送方对应的联系人情况，因此，信息应用2也无需向平行空间查询联系人情况，相应的，S805-S807是可选的步骤。
S812、响应于请求9，通知中心显示短信2对应的通知消息。
其中，短信2对应的通知消息可以仅包括预设提示信息(参考上文图16A所示的通知消息中的“1个通知”)。或者该通知消息可以包括短信2的具体内容，而不包括第一信息，如上述联系人2的名称等，从而在实现短信通知提醒的基础上，保护用户隐私，从而避免平行空间的内容的泄露。可选地，第一信息还可以包括其它信息，如发送方号码等。
其中，S812可以参考上述S809的相关内容。
在一些实施例中，响应于请求9，通知中心在电子设备当前显示的主空间的界面上显示短信2对应的通知消息。当用户想要查看短信2时，用户可以触发电子设备开启平行空间。电子设备响应于用户开启平行空间的操作，将平行空间切换至前台显示，如显示平行空间的桌面。该桌面上存在上述信息应用1的图标。响应于用户对该平行空间的图标的点击操作，电子设备显示包括短信列表，该短信列表可以包括短信2对应的条目。这里或替换描述为响应于用户对该平行空间的图标的点击操作，电子设备显示包括短信2的界面。
在一些实施例中，响应于请求9，通知中心在电子设备当前显示的主空间的界面上显示短信2对应的通知消息。当用户想要查看短信2时，用户可以点击该短信2的通知消息。在短信2属于平行空间的情况下，通知中心可以触发电子设备将平行空间切换至前台显示，以显示平行空间的信息应用1中的包括短信2的短信界面，实现由主空间到平行空间的自动跳转，从而实现短信2的快速查看。
示例性的，在平行空间处于未开启的情况下，通知中心可以直接向平行空间中的信息应用1发送携带有发送方号码的请求，响应于该请求，平行空间显示包括短信2的短信界面，实现短信2的快速查看。在平行空间未开启的情况下，通知中心可以先触发电子设备运行该平行空间，然后向平行空间中的信息应用1发送携带有发送方号码的请求，以触发平行空间显示包括短信2的短信界面。
其中，可选地，在由主空间切换至平行空间之前，需要进行身份验证，以保证安全性。
举例来说，用户点击如上述图17中(a)所示的在主空间内显示的通知消息94，电子设备可以显示如图17中(b)所示的身份验证界面。在身份验证成功后，电子设备前台显示如图17中(c)所示的平行空间的信息应用1的界面95，该界面95包括短信记录96，该短信记录96可以是短信2。
在一些实施例中，在接收到短信2后，还可以更新信息应用1的未读标记。以未读标记是数字为例，可以将该数字加1。如果平行空间处于未使用状态，信息应用2可以更新标记3，如将标记3加1，该标记3指示在平行空间未开启期间，接收到的与平行空间关联的短信的数量。之后，在平行空间处于使用状态时，平行空间中的信息应用1可以读取该标记3，更新信息应用1的图标的未读标记。参见图16A或图16B所示的信息应用1上的“+1”，表明该存在一个未读短信。
需要说明的是，上述显示未读标记仅是电子设备将平行空间切换至前台运行后，显示用于提示存在对SIM卡2的短信的第一提示信息的一种可能的实现方式，还可以是其它实现方式。比如，在显示主系统的界面(或称为第二界面)期间，在接收到与子系统关联的短信2后，如果该子系统处于未开启且信息隐藏功能开启的情况下，不显示短信2的发送方号码的第一信息。之后，响应于用户在该第二界面输入的操作(这里可以作为第二操作的一个示例)，电子设备显示子系统的桌面(这里可以作为第四界面的一个示例)，并在该桌面上显示第一提示信息，该第一提示信息指示在子系统处于未开启期间，电子设备接收到子系统关联的短信。其中，可选地，第二操作可以是对主系统的桌面上的子系统的图标的操作、手势操作、语音操作、或对主系统的设置应用提供的进入控件的操作等。
在一些实施例中，在接收到上述短信2后，如果平行空间处于后台运行，表明用户当前未在前台使用平行空间，则电子设备也可以不显示短信2对应的通知消息，其具体过程与上述在平行空间处于未使用状态的情况下，电子设备确定是否显示短信2对应的通知消息的过程类似。
上面介绍接收到的短信2与平行空间关联的情况，当然还存在短信2不与平行空间关联，而是与主空间关联的可能性。下面将继续介绍在与短信2关联的用户空间是主空间的情况下，电子设备显示短信2对应的通知消息的过程。
S813、在上述电子设备接收到的短信2与主空间关联的情况下，信息应用2向平行空间的联系人应用2发送请求10。其中，请求10用于包括短信2的发送方号码。
S814、响应于请求10，联系人应用2从联系人数据库2查询短信2的发送方号码所对应的联系人3的名称。
S815、联系人应用2向信息应用2发送联系人3的名称。
其中，S813-S815介绍的信息应用2查询短信2的发送方号码对应的联系人的过程可以参考上文S805-S808的相关过程，此处不再赘述。
S816、信息应用2向通知中心发送请求11。其中，请求11包括联系人3的名称和短信2。
S817、响应于请求11，通知中心显示短信2对应的通知消息。
其中，S816-S817可以参考上文S808-S809介绍的显示通知消息的过程。但可以理解的是在短信2属于主空间时，显示短信2对应的通知消息可以无需携带指示短信2属于主空间的对象。
在一些实施例中，上述S813-S817介绍的在短信2与主空间关联时，显示通知消息的过程可以是在主空间处于前台运行的情况下进行的。其中，主空间处于前台运行包括电子设备仅显示主空间的界面，和/或，电子设备同时显示主空间的界面以及平行空间的界面，如上述图1A所示。换言之，在主空间处于后台运行的情况下，电子设备可以不显示短信2对应的通知消息。
另外，在主空间处于后台运行的情况下，表明电子设备仅显示平行空间的界面，为了保护用户隐私，上述请求11可以不包括联系人3的名称，相应的，上述查询联系3的步骤也是可选的步骤。
在一些实施例中，上述通知消息可以是以弹窗的形式显示。在前台运行主系统期间，如果接收到子系统关联的短信，在子系统处于开启，且前台不可见的情况下，表明子系统在后台运行，则电子设备可以显示第一弹窗，该第一弹窗包括通知消息和第一图标，从而提醒用户接收到子系统关联的短信。该通知消息提示存在新信息，示例性的，该通知消息可以包括该短信、该短信的发送方号码以及子系统内该发送方号码所对应的联系人信息中的一个或多个。或者，该通知消息包括预设提示信息，如“1个通知”。
如果接收到主系统关联的短信，在子系统处于开启，且前台不可见的情况下，则电子设备可以显示第二弹窗，该第二弹窗包括通知消息，而不包括第一图标，实现上述主系统关联的短信的通知。同理，该通知消息可以包括该短信、该短信的发送方号码以及子系统内该发送方号码所对应的联系人信息中的一个或多个。或者，该通知消息包括预设提示信息，如“1个通知”。
需要说明的是，由于通知消息可以不包括短信2的具体内容，如上述图16A所示。因此，主空间也需要查询短信2的发送方所对应的联系人，因此，上述查询短信2的发送方所对应的联系人是可选的步骤。相应的，信息应用2向通知中心的请求也可以不用包括短信2的具体内容。
在一些实施例中，在短信2与主空间关联的情况下，用户也可以通过点击显示的通知消息触发电子设备直接显示包括短信2的界面。示例性的，响应于用户对该短信2对应的通知消息的点击操作，通知中心可以向主空间的信息应用2发送携带短信2的发送方号码的请求。之后，信息应用2响应于该请求，信息应用2显示包括短信2的短信界面，实现短信2的快速查看。
在一些实施例中，在短信2属于主空间的情况下，无论主空间是前台运行，还是后台运行，电子设备可以直接更新信息应用2的图标上的未读标记。
本申请实施例中，电子设备在接收到SIM卡2对应的短信2后，在该SIM卡2与子系统绑定的情况下，如果子系统处于未使用状态，且信息隐藏功能开启，表明用户不想要在子系统未使用时还显示关于子系统的短信2的通知消息。则电子设备可以停止显示短信2对应的通知消息，从而可以避免频繁显示不必要的通知消息，进而避免通知消息对用户使用主空间的干扰。并且，可以避免平行空间的用户数据的泄露，另外，也防止SIM卡1的泄露，保护用户隐私。
可以理解的是，在接收到短信2后，上文介绍的关于隐藏短信通知的过程是可选的，也就是说，电子设备在接收到短信2后，可以直接不显示短信2对应的通知消息。另外，上述短信发送过程也可以是可选的，也就是说，电子设备可以不使用上文介绍的短信发送过程发送短信，或者电子设备可以不支持发送短信。同理，上述短信接收过程也可以是可选的，也就是说，电子设备在接收到短信后，可以不使用上文介绍的短信接收过程，处理接收的短信，或者，电子设备可以不支持接收短信。
另外，上述通过对应用的图标的操作，显示应用的界面仅是一种示例，用户还可以通过其它操作，触发电子设备显示用户所需的界面，如手势、语音等。
需要说明的是，在平行空间与SIM卡2绑定之前，如果主空间接收到SIM卡2的短信3(或称为第一短信)，可以显示该短信3的通知消息，无需判断平行空间是否处于开启状态，也无需判断信息隐藏功能是否开启。其中，SIM卡2的短信3的发送方号码可以作为第一号码，短信3的通知消息可以作为第一号码的第一信息的一个示例。
上文模块或应用执行的操作仅是一种示例，该操作也可以是由其它模块或应用执行的，本申请不对该操作的执行主体做出限制。另外，上述模块或应用所执行的操作实际是模块或应用所属的用户空间执行的，如上述信息应用1通过联系人应用1查询联系人直接是平行空间查询联系人。但总得来说，上述操作均是电子设备执行的。
在一些实施例中，附图(如图1A)所示的“安全水印”仅是为了方便区分平行空间和主空间的界面。在实际应用中，平行空间的界面可以存在“安全水印”或与“安全水印”类似的指示信息，也可以不存在，本申请不对其做出限制。
在一些实施例中，上述是以平行空间与SIM卡2关联，主空间与SIM卡1关联介绍本申请的方案的，该平行空间也可以与SIM卡1关联，主空间与SIM卡2关联。换言之，平行空间(即子系统)可以与电子设备的第一SIM卡关联，主空间与电子设备的第二SIM卡关联，第一SIM卡与第二SIM卡不同，第一SIM卡是SIM卡1，第二SIM卡2是SIM卡2；或者，第一SIM卡是SIM卡2，第二SIM卡2是SIM卡1。
