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。
应了解，在本申请实施例的描述中，多个(或多项)的含义是两个以上，大于、小于、超过等理解为不包括本数，以上、以下、以内等理解为包括本数。如果有描述到“第一”、“第二”等只是用于区分技术特征为目的，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或者隐含指明所指示的技术特征的先后关系。
在第五代移动通信***(the fifth generation，5G)中引入了网络切片(network slice，NS)的概念，以应对不同通信业务对网络性能需求的差异。网络切片是可以提供特定网络功能、满足特定服务需求的逻辑网络，包括了完成特定功能或服务所需的网络功能模块和资源的集合。
参照图1，为本申请实施例提供的用户设备100(User Equipment，UE)的架构示意图，其中，该用户设备100包括监听模块101、切片管理模块102、连接管理模块103、切片选择模块104、加速模块105以及白名单管理模块106，其中：
监听模块101被设置成监听是否有应用启动并申请对应的网络切片；
切片管理模块102被设置成向网络侧申请、维持或者释放网络切片；
连接管理模块103被设置成配置网络接口及相关路由，以连接对应的网络切片；
切片选择模块104被设置成筛选网络切片；
加速模块105被设置成将待发送的数据分发至相应的网络切片进行传输；
白名单管理模块106被设置成供用户设置需要加速的目标应用的清单。
其中，用户设备100可以是无线终端，例如可以为移动电话、计算机、平板电脑、个人数码助理(personal digital assistant，PDA)、移动互联网设备(mobile Internet device，MID)、互联网协议(Internet Protocol，IP)电话、网络打印机和电子书阅读器(e-book reader)、车载设备、可穿戴设备、物联网终端设备，比如火灾检测传感器、智能水表/电表、智能单车、无人机、工厂监控设备等等。
其中，加速模块105可以是VPN加速模块。
参照图2，本申请实施例提供了一种数据传输方法，包括但不限于以下步骤201至步骤202：
步骤201：连接与目标应用对应的第一网络切片；
其中，在步骤201中，目标应用可以为视频类应用、游戏类应用等等，可以理解的是，目标应用是一类应用的总称，并不对其数量、类型等进行限定。
其中，目标应用可以携带有对应的DNN(Data Network Name，数据网络名称)，相应地，第一网络切片对应第一DNN，通过目标应用携带的第一DNN，切片管理模块102可以根据第一DNN申请对应的第一网络切片，具体地，切片管理模块102根据第一DNN申请对应的第一网络切片，可以是切片管理模块102根据第一DNN，在URSP(user equipment routing selection policy，用户设备100路由选择策略)规则信息中匹配到相应的S-NSSAI(Single Network Slice Selection Assistance information，单网络切片选择辅助信息)，然后向网络侧发起PDU(Protocol Data Unit，协议数据单元)会话创建请求，信令中携带该S-NSSAI。网络侧答复PDU会话创建接受，完成PDU会话建立流程。完成第一网络切片的申请以后，连接管理模块103配置相应的网络接口以及相关的路由，从而完成与目标应用对应的第一网络切片的连接。
步骤202：从第一网络切片以外的网络切片中确认第二网络切片，连接第二网络切片；
其中，在步骤202中，第二网络切片为第一网络切片以外的网络切片，即第二网络切片与第一网络切片是两个不同的网络切片，其中，第一网络切片和第二网络切片可以是同一个网络中的网络切片，也可以是不同网络中的网络切片。以用户设备100为手机进行举例说明，该手机可以是单卡单通手机，即该手机仅能***一张SIM卡(Subscriber Identification Module Card，用户识别卡)使用，在这种情况下，第一网络切片和第二网络切片均为同一SIM卡所驻留网络上的网络切片；另外，该手机也可以是双卡双通手机，即该手机可以***两张SIM卡使用，在这种情况下，第一网络切片和第二网络切片既可以是同一SIM卡所驻留网络上的网络切片，也可以是不同SIM卡所驻留网络上的网络切片。
类似地，确认第二网络切片后，连接管理模块103配置相应的网络接口以及相关的路由，从而完成与第二网络切片的连接。
步骤203：将目标应用待发送的数据分发至第一网络切片和第二网络切片上进行传输。
其中，在步骤203中，将目标应用待发送的数据分发至第一网络切片和第二网络切片，即同时利用第一网络切片和第二网络切片进行目标应用待发送的数据的传输。举例来说，可以将目标应用待发送的数据包分成两个数据包分别由第一网络切片和第二网络切片进行传输。通过同时连接不同的第一网络切片和第二网络切片，在传输数据时，将数据分发至第一网络切片和第二网络切片上，同时利用第一网络切片和第二网络切片对数据进行传输，有利于缓解网络拥塞和网络延时的问题，从而能够提升数据传输的速率，达到网络加速效果。
参照图3，作为一个示例，上述步骤201中，连接与目标应用对应的第一网络切片，具体可以包括以下步骤301至步骤302：
步骤301：获取目标应用的运行状态；
其中，在步骤301中，目标应用的运行状态可以是启动状态、后台状态或者是关闭状态，其中，启动状态可以是该目标应用从关闭状态启动，也可以是从后台状态切换至前台显示；后台状态可以是该目标应用在后台运行，关闭状态可以是该目标应用完全关闭。
步骤302：当目标应用的运行状态为启动状态并申请对应的第一网络切片，连接第一网络切片。
其中，在步骤302中，当目标应用的运行状态为启动状态并申请对应的第一网络切片时， 才连接第一网络切片，即并非任何时候都连接第一网络切片，能够有针对性地连接第一网络切片，降低用户设备100的整体能耗，优化用户设备100的运行效率。
参照图4，作为一个示例，上述步骤202中，从第一网络切片以外的网络切片中确认第二网络切片，具体可以包括以下步骤401至步骤402：
步骤401：获取预设的应用清单；
其中，在步骤401中，应用清单可以是用户预设的，既可以储存在本地，也可以储存在云端，应用清单可以采用列表的形式储存，应用清单里可以包含有应用名称、应用标识等参数。可以理解的是，每个目标应用在应用清单中可以有唯一的标识参数，从而便于提高判断目标应用是否属于应用清单的准确性。
步骤402：当确认目标应用属于应用清单，从第一网络切片以外的网络切片中确认第二网络切片。
其中，在步骤402中，确认目标应用是否属于应用清单，可以通过应用名称或者应用标识的匹配实现，当确认目标应用属于应用清单时，才从第一网络切片以外的网络切片中确认第二网络切片，即并非任何时候都从第一网络切片以外的网络切片中确认第二网络切片，能够有针对性地确认第二网络切片，降低用户设备100的整体能耗，优化用户设备100的运行效率。
作为示例，上述步骤202或者步骤402中，从第一网络切片以外的网络切片中确认第二网络切片，至少可以有以下四种实现方式：
第一种方式，可以从用户设备100当前建立的公共网络切片池中，根据网络质量参数筛选出除第一网络切片以外的网络切片作为第二网络切片。
其中，用户设备100可以有多个目标应用，每个目标应用可能都会申请各自对应的网络切片，用户设备100会建立对应的网络切片，以此形成该用户设备100的公共网络切片池，然后，可以根据网络质量参数从该公共网络切片池中筛选出除第一网络切片以外的网络切片作为第二网络切片，在一些实例中，网络质量参数可以是网络切片的时延、速率、丢包率中的一种或者多种。
其中，为了提高最终的数据传输速率，根据网络质量参数从该公共网络切片池中筛选出除第一网络切片以外的网络切片作为第二网络切片，可以是选择网络质量参数最优的网络切片作为第二网络切片，例如，可以选择时延最低的网络切片作为第二网络切片，或者选择速率最快的网络切片作为第二网络切片，或者选择丢包率最低的网络切片作为第二网络切片，或者可以综合上述三种网络质量参数进行选择。
举例来说，用户设备100的公共网络切片池中包含网络切片一、网络切片二和网络切片三，并且上述三个网络切片与第一网络切片均不相同，其中，网络切片一的时延最低，因此选择网络切片一作为第二网络切片。
第二种方式，可以根据第一网络切片对应的第一DNN，从URSP规则信息中筛选出除第一网络切片以外与第一DNN匹配的网络切片作为第二网络切片。
其中，目标应用在申请第一网络切片时，会携带有对应第一网络切片的第一DNN。在5G网络中，引入了URSP规则信息，即，5G核心网通过策略控制实体(policy control function，PCF)向终端设备提供其需要遵循的策略规则信息，这样，终端设备会根据URSP规则信息中的一个或者多个规则将应用要发送的数据进行路由，包括路由到一个已经建好的PDU会话，或 者触发建立一个新PDU会话。其中，URSP规则信息中包含有DNN与网络切片之间的匹配关系，并且同一个DNN可能匹配有多个不同的网络切片，并且每个不同的网络切片均有各自的连接优先级排序，其中，连接优先级越高的网络切片优先被连接。以第一DNN为例进行说明，URSP规则信息中可以包含第一DNN匹配的多个网络切片，其中第一网络切片的连接优先级最高，因而目标应用携带第一DNN时，会优先创建第一网络切片。而需要确认第二网络切片时，由于第一DNN还对应有其他网络切片，因此可以从第一DNN匹配的其他网络切片中选择一个网络切片作为第二网络切片。
其中，从第一DNN匹配的其他网络切片中选择一个网络切片作为第二网络切片，可以是选择除第一网络切片以外连接优先级最高的网络切片作为第二网络切片，即用户设备100最终连接的网络切片为：与第一DNN匹配的最高连接优先级的第一网络切片和与第一DNN匹配的次高连接优先级的第二网络切片，使得第一网络切片和第二网络切片与目标应用的匹配性更高，有利于提高最终的数据传输速率。
第三种方式，可以从网络侧提供的ALLOWED_NSSAI(Allowed Network Slice Selection Assistance information，允许网络切片选择辅助信息)列表中获取除第一网络切片以外的网络切片作为第二网络切片。
其中，ALLOWED_NSSAI列表中包含了用户设备100请求的NSSAI中，哪些S-NSSAI被网络侧允许了，可以供用户设备100连接，通过从网络侧提供的ALLOWED_NSSAI列表中获取除第一网络切片以外的网络切片作为第二网络切片，有利于扩大第二网络切片的选择范围。
第四种方式，目标应用可以同时携带有对应第一网络切片的第一DNN以及对应第二网络切片的第二DNN，因此，可以根据第二DNN确认对应的第二网络切片，由于第二DNN是确定的，这种方式有利于提高第二网络切片的确认效率，同时也可以降低用户设备100的整体能耗，优化用户设备100的运行效率。
参照图5，作为一个示例，上述步骤203中，将目标应用待发送的数据分发至第一网络切片和第二网络切片上进行传输，具体可以包括以下步骤501至步骤503：
步骤501：获取第一网络切片和第二网络切片的网络质量参数；
其中，在步骤501中，第一网络切片和第二网络切片的网络质量参数，可以是第一网络切片和第二网络切片的时延、速率、丢包率中的一种或者多种。
步骤502：根据第一网络切片和第二网络切片的网络质量参数确认第一网络切片和第二网络切片的数据承载量；
其中，在步骤502中，根据第一网络切片和第二网络切片的网络质量参数确认第一网络切片和第二网络切片的数据承载量，可以是第一网络切片和第二网络切片中网络质量参数较优的网络切片所对应数据承载量较大。以网络质量参数为时延进行举例说明，第一网络切片的时延比第二网络切片的时延要低，因此第一网络切片的数据承载量可以比第二网络切片的数据承载量要大。
步骤503：根据第一网络切片和第二网络切片的数据承载量将目标应用待发送的数据分发至第一网络切片和第二网络切片上进行传输。
其中，在步骤503中，根据第一网络切片和第二网络切片的数据承载量将目标应用待发送的数据分发至第一网络切片和第二网络切片上进行传输，即网络质量参数较优的网络切片的数据承载量较大，有利于提高数据分发的合理性，进一步提升数据传输的速率，达到网络 加速效果。以网络质量参数为时延进行举例说明，目标应用待发送的数据包括数据包一、数据包二和数据包三，若第一网络切片的时延比第二网络切片的时延低，将目标应用待发送的数据分发至第一网络切片和第二网络切片上进行传输，可以是将数据包一和数据包二分发至第一网络切片上进行传输，将数据包三分发至第二网络切片上进行传输。
在一实施例中，分发至第二网络切片的数据可以包括分发至第一网络切片的数据，能够实现备份功能，提高数据传输的稳定性。举例来说，目标应用待发送的数据包括有数据包一和数据包二，其中，根据数据分发规则，数据包一分发至第一网络切片，数据包二分发至第二网络切片，在实际传输时，数据包一同时分发至第二网络切片，即第一网络切片传输数据包一，第二网络切片传输数据包一和数据包二，在这种方式下，既能起到提升数据传输的速率的效果，又能提高数据传输的稳定性。
在上述实施例中，第二网络切片的数量可以是一个或者多个，而当第二网络切片的数量为多个时，其数量可以根据目标应用的网络质量参数或者预设的网络切片数量确定，其中，目标应用的网络质量参数可以是时延、速率、丢包率中的一种或者多种。
作为一个示例，第二网络切片的数量根据目标应用的网络质量参数确定时，将目标应用待发送的数据分发至第一网络切片和第二网络切片上进行传输后，可以获取目标应用的网络质量参数，若目标应用的网络质量参数未能达到预设值，则再确认并连接另一个第二网络切片，将目标应用待发送的数据分发至第一网络切片和两个第二网络切片进行传输，如此循环下去，直至目标应用的网络质量参数达到预设值。具体地，目标应用的网络质量参数达到预设值，若网络质量参数为时延，则预设值可以为1毫秒，当目标应用的数据传输时延小于1毫秒时认为目标应用的网络质量参数达到预设值；若网络质量参数为速率，则预设值可以为10兆字节/秒，当目标应用的数据传输速率大于10兆字节/秒时认为目标应用的网络质量参数达到预设值。可以理解的是，预设值可以根据实际情况设定，当然，本申请实施例中的网络质量参数也并不限定于时延、速率、丢包率。
作为一个示例，第二网络切片的数量根据预设的网络切片数量确定时，可以根据用户预设的网络切片数量确定，举例来说，用户预设的网络切片数量为三个，则连接三个第二网络切片。
可以理解的是，目标应用的网络质量参数或者预设的网络切片数量这两个判断条件，可以择一设置，也可以同时设置，当这两个判断条件同时设置时，可以设定满足任意一个条件即确定第二网络切片的数量，这种方式的好处在于，可以避免连接过多的第二网络切片，例如，为了达到较优的网络质量参数连接了过多的第二网络切片，或者，在第二网络切片的数量未达到用户预设的网络切片数量时已经达到较优的网络质量参数，此时也没有必要继续连接新的第二网络切片。
作为一个示例，还可以对目标应用当前的网络质量参数进行显示，便于用户可以直观地得知应用了本申请实施例的数据传输方法后的数据传输加速效果。
作为一个示例，还可以对目标应用当前的数据传输状态进行显示，其中，数据传输状态可以是表示当前的目标应用是否有使用本申请实施例的数据传输方法，例如，若当前的目标应用未使用本申请实施例的数据传输方法，则显示为“普通模式”，若当前的目标应用未使用本申请实施例的数据传输方法，则显示为“加速模式”。
