相关申请的交叉引用
本申请基于申请号为202011181482.7、申请日为2020年10月29日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及无线通信技术领域，特别涉及一种小区重选方法、终端以及计算机可读存储介质。
背景技术
在无线通信系统中，基站是给终端提供服务的设备，基站与终端之间通过电磁波进行无线通信。通过基站，无线通信系统可以为一定地理范围内的终端提供无线覆盖，这个地理范围称为小区。由于通信业务质量出错等原因，终端偶尔需要重新选区。而在一些情况中，通常采用增强信号强度的方式，或者增加一定的阈值或偏置量来控制终端的重选行为。
在一些情况中，针对多卡终端的情况，例如双卡终端，可能存在两张手机卡属于同一运营商，并且两张手机卡注册在同一基站上的情况，或者，可能存在两张手机卡分别属于不同运营商，并且两张手机卡注册在同一共享基站上的情况。在当前使用的手机卡由于当前所连接的基站出现异常而导致进行重新选区时，备用的手机卡也需要进行重新选区，由于两个手机卡会各自进行小区重选而各自与基站交互，因此会占用网络资源。
发明内容

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
需要说明的是，虽然在装置示意图中进行了功能模块划分，在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于装置中的模块划分，或流程图中的顺序执行所示出或描述的步骤。说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
本申请提供了一种小区重选方法、终端以及计算机可读存储介质，终端安装有第一USIM卡和第二USIM卡，第一USIM卡和第二USIM卡均注册到第一基站，终端在第一USIM卡完成小区重选而从第一基站重选到第二基站的情况下，会获取第二基站的基站参数信息，基站参数信息包括目标基站的最低接收电平、目标基站与原基站之间的偏置量、小区重选的迟滞值以及目标基站的优先级中的一种或多种。根据第二基站的基站参数信息完成第二 USIM卡的小区重选，即，利用通过第一USIM卡进行小区重选而获取到的重选基站后的基站参数信息，为第二USIM卡的小区重选提供数据参考，从而能够缩短第二USIM卡的小区重选耗时，并且能够避免第二USIM卡进行小区搜索而导致的网络资源占用。
下面结合附图，对本申请实施例作进一步阐述。
如图1所示，图1是本申请一个实施例提供的用于执行小区重选方法的系统架构的示意图。在图1的示例中，该系统架构包括终端110、第一基站120、第二基站130、运营商A核心网140以及运营商B核心网150。
其中，终端110被设置成向核心网请求无线通信，第一基站120与第二基站130分别被设置成在终端110与运营商A核心网140以及终端110与运营商B核心网150之间的数据传输，运营商A核心网140和运营商B核心网150被设置成将从基站收到的请求转接到不同的网络上。
在一实施例中，终端110安装有第一USIM卡和第二USIM卡，并且第一USIM卡与第二USIM卡均注册至第一基站120，通过第一基站120与运营商A核心网140进行数据传输。当终端110与第一基站120或第一基站120与运营商A核心网140之间的交互出现异常，第一USIM卡进行小区重选而从第一基站120重选至第二基站130，获取第二基站130的基站参数信息，并根据基站参数信息，对第二USIM卡进行小区重选。
本申请实施例描述的系统架构以及应用场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域技术人员可知，随着系统架构的演变和新应用场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本领域技术人员可以理解的是，图1中示出的系统架构的结构并不构成对本申请实施例的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
基于上述系统架构的结构，提出本申请的小区重选方法的各个实施例。
在一实施例中，如图2所示，图2是本申请一个实施例提供的小区重选方法的流程图。该小区重选方法应用于终端，该终端安装有第一USIM卡和第二USIM卡，且第一USIM卡和第二USIM卡均注册到第一基站。该方法包括但不限于有以下步骤：
步骤S110，在第一USIM卡进行小区重选而从第一基站重选到第二基站的情况下，获取第二基站的基站参数信息；
步骤S120，根据基站参数信息对第二USIM卡进行小区重选。
在一实施例中，当第一USIM卡正在进行业务发起，或是正在进行业务中，若第一基站无法发起对应的业务，或者无线质量无法保障业务的最低需求阈值，第一USIM卡进行小区重选。当第一USIM卡重选至第二基站，获取第二基站的基站参数信息，并根据第二基站的基站参数信息对第二USIM卡进行小区重选。通过第一USIM卡选取的驻留基站的基站参数信息，为第二USIM卡的小区重选提供了数据参考，以避免第二USIM卡在进行小区重选时仍需重新搜索的情况。该方法能够缩短第二USIM卡的小区重选耗时，并且能够避免第二USIM卡进行小区重选而导致的网络资源占用。
在一实施例中，使得第一USIM卡进行小区重选的原因为终端与基站交互信令异常或终端与基站交互数据质量差。在终端中有业务被触发的情况下，终端发起RRC(Radio Resource Control，无线资源控制)资源连接建立终端与基站的交互流程以及终端与核心 网的交互流程，当终端与基站的交互出现异常，即，由于当前基站太拥挤或受到信号干扰等原因，导致无法完成当前业务，因此，注册在该基站的USIM卡需要进行小区重选；或者是，在终端中有业务被触发并且终端能够正常与基站进行交互的情况下，监测到以下任意情况，进行小区重选：数据吞吐量不达标；信号干扰大，误码率高，导致信噪比过低。本实施例不对触发小区重选的原因作具体限定。
在一实施例中，在终端与基站交互信令异常或终端与基站交互数据质量差的情况下，终端数次控制USIM卡重连基站并发起业务，若均未能正常进行数据传输，控制USIM卡进行小区重选。在进行小区重选前针对原基站进行若干次重连以确认该基站无法使用，能够避免USIM卡进行小区重选导致的网络资源占用。
在一实施例中，本申请提供了小区重选方法应用于5G技术(5th generation mobile networks，第五代移动通信技术)中。此外，该小区重选方法还能够应用于4G技术(the4th generation mobile communication technology，第四代移动通信技术)中，本实施例不对其使用范围做限定。
另外，在一实施例中，如图3和图4所示，图3是本申请一个实施例提供的网络架构的场景示意图；图4是本申请一个实施例提供的当第一USIM卡和第二USIM卡属于不同运营商时的重选方法的流程图。步骤S120还包括但不限于有以下步骤：
步骤S210，根据基站参数信息确定第二基站为共享基站；
步骤S220，控制第二USIM卡注册到第二基站。
在一实施例中，当安装在同一终端的第一USIM卡与第二USIM卡不属于同一运营商，并且第一USIM卡与第二USIM卡均注册在同一共享基站的情况下，对于该终端来说，第一USIM卡与第二USIM卡对应的无线参数是完全一致的，例如信号强度以及信号测量参数。因此，只需对第一USIM卡注册的网络进行网络质量评估，评估结果能够被第二USIM卡直接使用。这能够缩短第二USIM卡进行小区重选的耗时，并且避免了第二USIM卡进行小区重选而导致的网络资源占用。
在一实施例中，参考图3，在第一USIM卡与第二USIM卡不属于同一运营商的情况下，当第一USIM卡驻留的第一基站出现异常，第一USIM卡进行小区重选并重选至第二基站，获取第二基站的基站参数信息。然后根据基站参数信息确认第二基站是否为共享基站。如果第二基站是共享基站，控制第二USIM卡选择第二基站作为驻留基站。这使得第二USIM卡无需再重新检索一遍所有基站的具体情况，缩短了小区重选的耗时，减少了网络资源的占用。
在一实施例中，在第一USIM卡与第二USIM卡均已完成小区重选并由第一基站重选至第二基站后，一定时间间隔后当第二基站出现异常，USIM卡需要进行小区重选，此时会将第一基站作为小区重选的检测目标。本实施例不对该时间间隔作具体限定。
另外，在一实施例中，如图5和图6所示，图5是本申请一个实施例提供的网络架构的场景示意图；图6是本申请一个实施例提供的当第一USIM卡和第二USIM卡属于不同运营商时的重选方法的流程图。步骤S120还包括但不限于有以下步骤：
步骤S310，根据基站参数信息确定第二基站不为共享基站；
步骤S320，控制第二USIM卡从除第一基站和第二基站之外的基站中选择驻留基站。
在一实施例中，参考图5，可以理解的是，当安装在同一终端的第一USIM卡与第二 USIM卡不属于同一运营商的情况下，当第一USIM卡驻留的第一基站出现异常，第一USIM卡进行小区重选并重选至第二基站，获取第二基站的基站参数信息。然后根据基站参数信息确认第二基站是否为共享基站。如果第二基站不是共享基站，第二USIM卡无法选择第二基站作为驻留基站。因此，控制第二USIM卡从除第一基站和第二基站之外的基站中选择驻留基站。当第一USIM卡与第二USIM卡不属于同一运营商，第一USIM卡提供的基站参数信息能够为第二USIM卡排除第二USIM卡无法注册的基站，缩短了第二USIM卡进行小区重选所需的时间。
另外，在一实施例中，参照图7和图8，图7是本申请一个实施例提供的网络架构的场景示意图；图8是本申请一个实施例提供的当第一USIM卡和第二USIM卡属于同一运营商时的重选方法的流程图。步骤S120还包括但不限于有以下步骤：
步骤S410，根据基站参数信息使第二USIM卡注册到第二基站。
在一实施例中，参照图7，当安装在同一终端的第一USIM卡和第二USIM卡属于同一运营商，第一USIM卡与第二USIM卡可选择同一基站驻留。可以理解的是，当第一USIM卡驻留的第一基站出现异常，第一USIM卡进行小区重选并重选至第二基站，获取第二基站的基站参数信息。由于第一USIM卡与第二USIM卡属于同一运营商，控制第二USIM卡直接注册至第二基站。第二USIM卡在进行小区重选时以第一USIM卡提供的数据作为参考，无需再重新检索一遍所有基站的具体情况，能够缩短第二USIM卡的小区重选耗时，并且能够避免第二USIM卡进行小区重选而导致的网络资源占用。
为了更加清楚的说明上述各个实施例中信息处理方法的具体步骤流程，下面以具体的示例进行说明。
示例一：

需要说明的是，本实施例中的终端，可以包括有如图1所示实施例中的系统架构，本实施例中的终端和如图1所示实施例中的系统架构属于相同的发明构思，因此这些实施例具有相同的实现原理以及技术效果，此处不再详述。
