相关申请的交叉引用
本申请基于申请号为202010881130.6、申请日为2020年08月27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
本申请实施例涉及但不限于无线通信技术领域，尤其涉及一种转卡切片切换方法、设备及存储介质。
背景技术
网络切片技术(Network Slicing)，最简单的理解，就是将一个物理网络切割成多个虚拟的端到端的网络，每个虚拟网络之间，包括网络内的设备、接入、传输和核心网，是逻辑独立的，任何一个虚拟网络发生故障都不会影响到其它虚拟网络。每个虚拟网络具备不同的功能特点，面向不同的需求和服务。
目前，终端都只有一套射频，所以数据业务只能选定一个卡常驻。具有多卡多待功能的终端，在进行转卡切换的时候，无法实现当前卡的切片到待转入目标卡的切片的切换。例如，市面上的双卡双待手机只能选定一个卡常驻，经常在现网下发现，若卡1和卡2不是同一个运营商，则信号有差异，若直接将卡1的转卡切片切换到卡2的切片，由于卡1和卡2获得的可用切片服务是不同的，无法实现卡1的切片到卡2的切片的切换，从而导致切片连接服务质量较低。

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。不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
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”、“第三”、“第四”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。
网络切片技术就是将一个物理网络切割成多个虚拟的端到端的网络，每个虚拟网络之间，包括网络内的设备、接入、传输和核心网，是逻辑独立的，任 何一个虚拟网发生故障都不会影响到其他虚拟网络。每个虚拟网络具备不同的功能特点，面向不同的需求和服务。网络切片技术带来如下价值：保证不同等级业务的服务质量，包括带宽、延迟、丢包和抖动等传统网络指标，使用户可以获得一个逻辑上独立的网络，避免网络风险，同时避免泄密；用户可以查看自己的切片套餐有关的网络统计指标和状态。
终端在进行网络注册时(如5G网络注册)，与网络协商或由网络提供一个切片集合的网络切片选择辅助信息(Network Slice Selection Assistance Information，NSSAI)以获得切片相关信息，切片相关信息包括切片内的数据网络名称(Data Network Name，DNN)。而终端内含有UE路由器选择策略(UE Route Selection Policy，URSP)，且UE路由器选择策略中含有网络切片选择策略(Network Slice Selection Policy，NSSP)，终端中的应用按照网络切片选择策略选择切片，网络切片选择策略的元素包含数据网络名称、应用ID(Application ID)等，且应用可以选择网络切片选择策略中的元素来匹配网络切片选择策略。运营商可以为UE预配置UE路由选择策略，或由PCF动态下发或者更新UE路由选择策略。
传统的终端只有一套射频模块，所以数据业务智能选定一个卡(如SIM卡、baiMicro-SIM卡和Nano-SIM卡等)常驻，经常在现网下发现，如果终端内任意两张的卡不是同一个营运商，则该两张卡对应的网络信号有差异。假设某应用在当前卡上使用切片，需要将当前卡切换到待转入目标卡，由于当前卡的切片集合和待转入目标卡的切片集合不同，前卡切换到待转入目标卡后，应用使用的切片切换到待转入目标卡对应的切片，则无法实现将该应用使用的切片从当前卡切换到待转入目标卡，一定程度上影响用户应用的使用，则降低切片连接服务质量。
基于此，本申请实施例提供了转卡切片切换方法、设备及存储介质，能够完成切片从当前卡向待转入目标卡的切换，达到不影响用户应用使用，且可以提高切片连接服务质量。
第一方面，参照图1，本申请实施例公开了一种转卡切片切换方法，包括：
S1000、获取转卡切片切换信号；
S2000、根据转卡切片切换信号、当前卡的应用网络使用状态和预设的切片数据库，得到可切换切片；切片数据库包含应用网络使用状态和待转入目标卡的可切换切片之间的匹配信息；
S3000、根据可切换切片进行转卡切片切换。
在一些实施例中，当终端完成当前卡和待转入目标卡的网络注册后，在网 络注册信令交互过程中，分别获得当前卡和待转入目标卡网络支持的切片集合。将当前卡和待转入目标卡的切片集合进行比对，以根据匹配信息获取当前卡和待转入目标卡的切片以得到可切换切片，并将可切换切片存储于切片数据库中。
当接收到转卡切片切换信号，根据转卡切片切换信号、当前卡的应用网络使用状态和预设的切片数据库得到可切换切片。由于切片为5G网络的应用技术，若当前卡的网络类型为2G、3G、4G网络中的任意一种，而待转入目标卡的网络类型为5G网络，则当前卡没有使用切片，根据转卡切片切换信号和预设的切片数据库得到可切换切片，也即当前卡切换到待转入目标卡后应用可以使用的切片。若当前卡和待转入目标卡的网络类型都为5G网络，当前卡的应用网络使用状态相当于当前卡的应用使用的切片，则根据当前卡的应用网络使用状态和待转入目标卡的可切换切片之间的匹配信息，得到可切换切片，即可根据可切换切片进行转卡切片切换，使当前卡切换到待转入目标卡时，完成从当前卡到待转入目标卡的切片切换，既不影响用户应用的使用，又可以提高切片连接服务质量。
在一些实施例中，切片数据库包括：可切换切片数据库和可替换切片数据库，可切换切片数据库包括当前卡和待转入目标卡中流量描述符相同的切片之间的匹配信息；和/或，可替换切片数据库包括当前卡和待转入目标卡中替换参数相匹配的切片之间的匹配信息。
流量描述符为一组用于在一个给定的标准接口上描述一个IP流的流量特性的流量参数，流量描述符包含但不限于数据网络名称、应用ID、IP-3Tuple、Non-IP描述器(Non-IP descriptors)。当前卡和待转入目标卡完成网络注册后，当前卡和待转入目标卡会获取切片集合，然后对当前卡的切片集合和待转入目标卡的切片集合进行分析，将当前卡和待转入目标卡中流量描述符相同的切片之间的匹配信息存储至可切换切片数据库，然后在剩余的切片中查找当前卡和待转入目标卡中替换参数相匹配的切片之间的匹配信息存储至可替换切片数据库。通过可切换切片数据库包含当前卡和待转入目标卡中流量描述符相同的切片之间的匹配信息，可替换切片数据库包含当前卡和待转入目标卡中替换参数相匹配的切片之间的匹配信息，以便于根据当前卡的应用网络使用状态获取不同数据库内的可切换切片，以便于在当前卡切换到待转入目标卡后，待转入目标卡的应用使用的切片更加贴合当前卡应用使用的切片。
在一些实施例中，替换参数包括以下一种或多种：服务质量参数(Qos)、带宽参数和延时参数。
由于可切换切片数据库包含当前卡和待转入目标卡中流量描述符相同的切 片之间的匹配信息，当前卡和待转入目标卡的切片集合中除去可切换切片数据库的切片后得到剩余切片，可替换切片数据库则包含剩余切片中选择替换参数相匹配的切片之间的匹配信息。通过在剩余切片中将服务质量参数和/或带宽参数和/或延时参数相匹配的切片筛选出来，以得到可替换切片数据库的切片之间的匹配信息。
在一些实施例中，参照图2，一种转卡切片切换方法，还包括：
S4000、获取切片变更信号；
S5000、根据切片变更信号更新可切换切片数据库和/或可替换切片数据库；
当终端运行过程中，当前卡的应用网络使用状态是变化的，因此当前卡使用的切片也是不同的。通过无线协议栈订阅切片变更消息以获取切片变更信号，若当前卡的切片集合发生变更，则获取到切片变更信号，根据切片变更信号更新可切换切片数据库和/或可替换切片数据库，以便于通过更新的可切换切片数据库和可替换切片数据库获取更加准确的可切换切片。
在一些实施例中，参照图3，一种转卡切片切换方法还包括：
S6000、监测和对比当前卡和待转入目标卡的网络质量；
S7000、若待转入目标卡的网络质量优于当前卡的网络质量，输出转卡切片切换信号。
通过监测和对比当前卡和待转入目标卡的网络质量，若待转入目标卡的网络质量优于当前卡的网络质量，则输出转卡切片切换信号。通过自动监测当前卡和待转入目标卡的网络质量，实现自动进行当前卡和待转入目标卡的自动转换，既节省人力又能够时刻保持当前应用的网络质量最佳。其中，终端内至少有两张以上的用户识别卡，而当前使用的用户识别卡为当前卡，而终端中除了当前卡，其他用户识别卡中网络质量最优的用户识别卡为待转入目标卡。因此，先将其他用户识别卡的网络质量进行监测和对比以筛选出网络质量最优的用户识别卡为待转入目标卡，然后再将待转入目标卡和当前卡进行监测比对，若待转入目标卡的网络质量优于当前卡的网络质量才输出转卡切片切换信号，以根据转卡切片切换信号进行转卡，使得终端使用的用户识别卡的网络质量保持最优，从而提高了用户体验感。
在其他实施例中，根据用户点击转卡切换按键以输出转卡切片切换信号，也即手动实现当前卡切换到待转入目标卡，根据转卡切片切换信号、当前卡的应用网络使用状态和预设的切片数据库获取可切换切片，并根据可切换切片进行转卡切片切换。采用手动将当前卡切换到待转入目标卡，则无需考虑待转入目标卡和当前卡的网络质量，且待转入目标卡则为用户选定需要转换的用户识 别卡。通过手动将当前卡切换到待转入目标卡，以便于根据用户需求进行用户识别卡的切片。
在一些实施例中，网络质量包括以下一种或多种：参考信号接收功率(RSRP)、参考信号接收质量(RSRQ)、信噪比(SNR)、频段带宽(Bandwith)、网络类型和网络拥塞状况。监测和对比当前卡和待转入目标卡的网络质量具体为监测和对比当前卡和待转入目标卡的参考信号接收功率、参考信号接收质量、信噪比、频段带宽、网络类型和网络拥塞状况中的任意一种或多种。若当前卡的参考信号接收功率、参考信号接收质量、信噪比任意一值低于预设门限值，或者频段带宽过低无法满足切片服务质量，或者网络类型为非5G网络，或者出现网络拥塞，而待转入目标卡的参考信号接收功率、参考信号接收质量、信噪比高于当前卡的参考信号接收功率、参考信号接收质量、信噪比，且待转入目标卡的频段带宽、网络类型满足切片服务质量，则输出转卡切片切换信号。通过监测和对比当前卡和待转入目标卡的网络质量具体为监测和对比当前卡和待转入目标卡的参考信号接收功率、参考信号接收质量、信噪比、频段带宽、网络类型和网络拥塞状况中的任意一种或多种，以更加准确地判断当前卡和待转入目标卡的网络质量后准确地输出转卡切片切换信号。
在一些实施例中，参照图4，应用网络使用状态包括：保全切片应用网络使用状态和非保全切片应用网络使用状态；
根据转卡切片切换信号、当前卡的应用网络使用状态和预设的切片数据库，得到可切换切片，包括：
S2100、获取应用的应用工作状态，应用工作状态包括以下一种或多种：前后台状态、流量状态、活动态的线程类别和使用频率；
S2200、根据应用的应用工作状态确定应用网络使用状态为保全切片应用网络使用状态；
S2300、根据保全切片应用网络使用状态和切片数据库得到可切换切片。
终端在运行过程中，通过实时监控应用的应用工作状态，主要监控应用的前后台状态、流量状态、活动态的线程类别以及使用频率中任意一种或多种，以确定应用网络使用状态为保全切片应用网络使用状态。其中，保全切片应用网络使用状态为当前卡转换到待转入目标卡后应用需要继续提供切片服务。若当前卡转换到待转入目标卡后所有应用都需要提供切片服务，一方面难以匹配所有应用的切片，另一方面所有应用的切片切换的工程量也巨大。因此通过应用的应用工作状态确定应用网络使用状态为保全切片应用网络使用状态，然后根据保全切片应用网路使用状态和切片数据库得到可切换切片，既可过滤掉一 些不重要的应用，以节省切片附图提供的数量，又能不降低当前卡转换到待转入目标卡后的切片服务质量。
在一些实施例中，参照图5，步骤S2200具体包括：
S2210、若应用的前后台状态为前台应用，应用网络使用状态为保全切片应用网络使用状态；
S2220、若应用的前后台状态为后台应用，根据流量状态和/或活动态的线程类别和/或使用频率确定应用网络使用状态为保全切片应用网络使用状态。
通过分析应用的前后台状态，以判断应用的前后台状态为前台应用还是后台应用，针对前台应用则需要保全该前台应用使用的切片，以在当前卡切换到待转入目标卡后，前台应用则需要继续提供切片服务。对于后台应用则根据应用的流量状态和/或活动态的线程类别和/或使用频率确定该后台应用使用的切片是否需要保全下来，进而确定当前卡切换到待转入目标卡后，该后台应用是否需要继续提供切片服务。
通过确定应用的前后台状态，以判断在当前卡切换到待转入目标卡后，该应用是否需要继续提供切片服务，既能维持重要的应用继续拥有高质量的切片服务质量，又能提高切片切换的效率。
在一些实施例中，参照图6，步骤S2220具体包括：
S2221、若后台应用的流量状态为单位时间内产生的流量超过预设流量阈值，应用网络使用状态为保全切片应用网络使用状态；
S2222、和/或，若后台应用的活动态的线程类别为必需工作场景，应用网络使用状态为保全切片应用网络使用状态；
S2223、和/或，若后台应用的使用频率超过预设频率阈值，应用网络使用状态为保全切片应用网络使用状态。
其中，预设流量阈值可以根据不同的后台应用设置不同的预设流量阈值，例如对于视频类后台应用损耗的流量较大，对于阅读类后台应用或者短信后台应用则损耗的流量较少，因此根据不同后台应用设置的预设流量阈值不同，以通过判断后台应用在单位时间内产生的流量是否超过预设流量阈值以确定该后台应用对于用户的重要性，若后台应用的流量状态为单位时间内产生的流量超过预设流量阈值，则应用网络使用状态为保全切片应用网络使用状态，也即在当前卡切换到待转入目标卡后，该后台应用使用切片服务需要继续提供。若后台应用的流量状态为单位时间内产生的流量未超过预设流量阈值，则应用网络使用状态为非保全切片应用网络使用状态，也即在当前卡切换到待转入目标卡后，该后台应用无需提供切片服务。
对于活动态的线程类别为必需工作场景，如下载类线程、支付类线程为默认的必需工作场景，且必需工作场景可以根据需求预先设置，以针对不同应用预先设定其应用程序组件活动为必需工作场景，一旦监测到后台应用当前的应用程序组件为预设的，则认定该后台应用的活动态的线程类别为必需工作场景，则根据后台应用的活动态的线程类别为必需工作场景，则应用网络使用状态为保全切片应用网络使用状态，也即在当前卡切换到待转入目标卡后，该后台应用使用的切片服务需要继续提供。若检测应用的活动态的线程类别为非必需场景，则应用网络使用状态为非保全切片应用网络使用状态。也即在当前卡切换到待转入目标卡后，该后台应用无需提供切片服务。
对于后台应用的使用频率是否超过预设频率阈值，以判断应用网络使用状态为保全切片应用网络使用状态还是非保全切片应用网络使用状态。其中，预设频率阈值可以根据用户自行设置，也可以根据所有后台应用被调用的频率的平均值确定。具体地，通过在一段周期内判断后台应用的使用频率是否超过预设频率阈值，若在一段周期内后台应用的使用频率超过预设频率阈值，证明该后台应用为用户常使用应用，则应用网络使用状态为保全切片应用网络使用状态，也即在当前卡切换到待转入目标卡后，后台应用使用的切片服务需要继续提供。若在一段周期内后台应用的使用频率未超过预设频率阈值，则应用网络使用状态为非保全切片应用网络使用状态，也即在当前卡切换到待转入目标卡后，无需提供后台应用切片服务。
由于流量状态和/或活动态的线程类别和/或使用频率能够代表后台应用对于用户的重要性，因此通过判断流量状态和/或活动态的线程类别和/或使用频率确定应用网络使用状态为保全切片应用网络使用状态，进而确定当前卡切换到待转入目标卡后，后台应用是否需要继续提供切片服务，以针对用户而言重要的后台应用则继续提供切片服务，以便于当前卡切换到待转入目标卡后，用户继续能够使用该后台应用。对于用户而言不重要的后台应用，在当前卡切换到代转入目标卡后，则不再对该后台应用提供切片服务，既能够减少终端的运行空间，又能提高切片转换的效率。
在一些实施例中，参照图7，切片数据库包括可切换切片数据库，步骤2300具体包括：
S2310、检测当前卡的应用的切片使用行为；
S2320、根据应用的切片使用行为确定保全切片应用网络使用状态为特定切片应用网络使用状态；
S2330、根据特定切片应用网络使用状态获取特定切片；
S2340、根据特定切片在可切换切片数据库中查询，获取可切换切片数据库中与特定切片相匹配的切片，以得到可切换切片。
当切片数据库内包括可切换切片数据库，则根据应用的切片使用行为确定保全切片应用网络使用状态为特定切片应用网络使用状态，对于特定切片应用网络使用状态则认为当前卡切换到待转入目标卡后，应用使用的切片服务不变。因此，根据特定切片应用网络使用状态获取特定切片，并在可切换切片数据库内查询特定切片，若在可切换切片数据库中存在与特定切片相匹配的切片，则获取该切片以得到可切换切片，以便于根据可切换切片进行转卡切片切换，由于可切换切片数据库中包括当前卡和待转入目标卡流量描述符相同的切片，所以在可切换切片数据库中获取与特定切片相匹配的切片得到的可切换切片，则当前卡切换到待转入目标卡后，应用的切片服务质量提高。
在一些实施例中，参照图8，切片数据库包括可替换切片数据库，步骤S2300包括：
S2350、检测当前卡的应用的切片使用行为；
S2360、根据应用的切片使用行为确定保全切片应用网络使用状态为系统默认切片应用网络使用状态；
S2370、根据系统默认切片应用网络使用状态获取系统默认切片；
S2380、根据系统默认切片在可替换切片数据库中查询，获取可替换切片数据库中与系统默认切片相匹配的切片，以得到可切换切片。
检测当前卡的应用的切片使用行为，通过应用的切片使用行为确定保全切片应用网络使用状态为系统默认切片应用网络使用状态，对于系统默认切片应用网络使用状态，需要在当前卡切换到待转入目标卡后，应用使用的切片只需要不影响服务质量即可。因此，根据系统默认切片应用网络使用状态获取系统默认切片，然后根据系统默认切片在可替换切片数据库中查询，以通过匹配信息在可替换切片数据库中获取与系统默认切片相匹配的切片以得到可切换切片。通过在可替换切片数据库获取与系统默认切片相匹配的切片以得到可切换切片，以便于针对切片服务质量要求不高的应用，在当前卡切换到待转入目标卡后，应用能够继续使用相同切片服务质量的切片，不影响应用的继续使用。
在一些实施例中，参照图9，步骤2000还包括：
S2400、若切片数据库中不存在可切换切片；
S2500、更新切片数据库以得到二次切片数据库；
S2600、根据当前卡的应用网络使用状态和二次切片数据库，得到可切换切片。
若切片数据库内不存在可切换切片，则证明切片数据库内没有匹配到应用使用的切片，若强行进行切片切换则应用使用的切片服务质量会改变。因此，通过更新切片数据库以得到二次切片数据库，再通过应用网络使用状态和二次切片数据库得到可切换切片，以便于应用能够使用切片质量不变。
在一些实施例中，得到二次切片数据库后，通过应用的切片使用行为判断确定保全切片应用网络使用状态为特定切片应用网络使用状态或系统默认切片应用网络使用状态，若为特定切片应用网络使用状态则获取特定切片，根据特定切片在二次切片数据库中查询，以获取与特定切片相匹配的切片以得到可切换切片，以便于在更新后的二次切片数据库内查询到应用使用的特定切片，从而提高应用使用的切片服务质量。若为系统默认切片应用网络使用状态，获取系统默认切片，并根据系统默认切片在二次切片数据库内查询，以获取与系统默认切片相匹配的切片以得到可切换切片，以便于应用能够保持使用切片服务质量不变的系统默认切片。
具体地，二次切片数据库包括二次可切换切片数据库和二次可替换切片数据库，若可切换切片数据库中不存在与特定切片相匹配的切片和/或可替换切片数据库内不存在与系统默认切片匹配的切片；更新可切换切片数据库和可替换切片数据库，以形成二次可切换切片数据库和二次可替换切片数据库；根据特定切片、系统默认切片在二次可切换切片数据库和二次可替换切片数据库中查询，获取二次可切换切片数据库中与特定切片相匹配的切片和/或二次可替换切片数据库中与系统默认切片相匹配的切片，以得到可切换切片。
若可切换切片数据库中不存在与特定切片相匹配的切片和/或可替换切片数据库中不存在与系统默认切片匹配的切片，则需要重新获取当前卡的切片集合和待转入目标卡的切片集合，然后重新获取当前卡的切片集合和待转入目标卡的切片集合中流量描述符相同的切片以得到二次可切换切片数据库，重新获取当前卡的切片集合和待转入目标卡的切片集合中替换参数相匹配的切片以得到二次可替换切片数据库。得到二次可切换切片数据库和二次可替换切片数据库后，获取二次可切换切片数据库中与特定切片相匹配的切片和二次可替换切片数据库中与系统默认切片相匹配的切片以得到可切换切片，以便于根据可切换切片进行转卡切片切换。
在一些实施例中，参照图10，一种转卡切片切换方法还包括：
S8000、若二次切片数据库内不存在可切换切片；
S9000、输出转卡切换提示信号；
S1100、接收操作指令；
S1200、根据操作指令进行切片的转卡切换。
具体地，步骤S8000具体为若二次可切换切片数据库中不存在与特定切片相匹配的切片和/或二次可替换切片数据库内不存在与系统默认切片相匹配的切片。
其中，转卡切换提示信号为“当前卡的信号质量太差，需要切换到待转入目标卡，但会影响某些应用使用切片数据”，以通过切换提示信号提示用户是否需要进行切片切换。其中输出转卡切换提示信号时也输出切片不匹配的应用名单，以便于用户能够清楚哪些应用在当前卡切换到待转入目标卡后受到影响，从而判断是否需要进行转卡切换。若用户同意当前卡切换到待转入目标卡，则可通过人机交互装置(如按键、触摸屏等)接收到用户输入终端的操作指令，以根据操作指令进行切片的转卡切换。若用户拒绝进行转卡切换，则可通过人机交互装置(如按键、触摸屏)接收到拒接指令，以根据拒绝指令停止当前卡切换到待转入目标卡。
综上，当前卡和待转入目标卡完成网络注册后，获取当前卡的切片集合和待转入目标卡的切片集合。获取当前卡的切片集合和待转入目标卡的切片集合中流量描述相匹配的切片之间的匹配信息以得到可切换切片数据库，当前卡和待转入目标卡的切片集合中除去可切换切片数据库的切片后得到剩余切片，在剩余切片中将服务质量参数和/或带宽参数和/或延时参数相匹配的切片筛选出来，以获取该切片之间的匹配信息以得到可替换切片数据库。监测和对比当前卡和待转入目标卡的网络质量具体为监测和对比当前卡和待转入目标卡的参考信号接收功率、参考信号接收质量、信噪比、频段带宽、网络类型和网络拥塞状况中的任意一种或多种。若当前卡的参考信号接收功率、参考信号接收质量、信噪比任意一值低于预设门限值，或者频段带宽过低无法满足切片服务质量，或者网络类型为非5G网络，或者出现网络拥塞，而待转入目标卡的参考信号接收功率、参考信号接收质量、信噪比高于当前卡的参考信号接收功率、参考信号接收质量、信噪比，且待转入目标卡的频段带宽、网络类型满足切片服务质量，则输出转卡切片切换信号。获取转卡切片切换信号以判断应用的前后台状态，若应用的前后台状态为前台应用，应用网络使用状态为保全切片应用网络使用状态，则当前卡切换到待转入目标卡后，需要对应用提供切片服务。若应用的前后台状态为后台应用，若后台应用的流量状态为单位时间内产生的流量超过预设流量阈值，应用网络使用状态为保全切片应用网络使用状态，或者后台应用的活动态的线程类别为必需工作场景，则应用网络使用状态为保全切片应用网络使用状态，或者后台应用在一段周期内使用判断超过预设频率阈值， 则应用网络使用状态为保全切片应用网络使用状态。对于保全切片应用网络使用状态，判断当前卡的应用的切片使用行为，根据应用的切片使用行为确定保全切片应用网络使用状态为特定切片应用网络使用状态或系统默认切片应用网络使用状态。根据特定切片应用网络使用状态获取特定切片，根据系统默认切片应用网络使用状态获取系统默认切片，然后根据特定切片在可切换切片数据库中查询，根据系统默认切片在可替换切片数据库中查询，以通过匹配信息在可切换切片数据库中获取到与特定切片相匹配的切片和/或在可替换切片数据库中获取与系统默认切片相匹配的切片以得到可切换切片，根据可切换切片进行转卡切片切换。若可切换切片数据库中不存在与特定切片相匹配的切片和/或可替换切片数据库内不存在与系统默认切片匹配的切片。重新获取当前卡的切片集合和待转入目标卡的切片集合中流量描述符相同的切片以得到二次可切换切片数据库，重新获取当前卡的切片集合和/或待转入目标卡的切片集合中替换参数相匹配的切片以得到二次可替换切片数据库。得到二次可切换切片数据库和二次可替换切片数据库后，获取二次可切换切片数据库中与特定切片相匹配的切片和二次可替换切片数据库中与系统默认切片相匹配的切片以得到可切换切片，根据可切换切片进行转卡切片切换。若二次可切换切片数据库中不存在与特定切片相匹配的切片和/或二次可替换切片数据库内不存在与系统默认切片相匹配的切片，输出转卡切换提示信息，若用户同意当前卡切换到待转入目标卡，则接收到操作指令，以根据操作指令进行切片的转卡切换。
