此外，下面所描述的本申请各个实施例中所涉及到的技术特征只要彼此之间未构成冲突就可以相互组合。
本申请提供了一种数据传输异常恢复方法及装置，该方法及装置应用于终端设备，从而使得该终端设备能够缩短恢复数据传输异常的时间，并且能够避免在恢复数据传输异常时频繁出现无服务状态，提高了用户体验。
下面，将通过具体实施例对本申请进行阐述。
请参阅图1，是本申请实施例提供的一种实施环境的结构示意图，该实施环境包括：终端设备100、接入网200和核心网300。
其中，终端设备100为手机、平板电脑、智能手表等能够进行网络通信的设备。当终端设备100需要获取网络侧的服务时，终端设备100需要与接入网200建立RRC连接，并在核心网300中注册网络(attach)，以在核心网300中登记身份信息和位置信息并激活默认承载，此时，若终端设备100的数据连接处于激活状态，则终端设备100能够与网络建立起对应的用户面数据承载通道，实现数据传输。
在终端设备100数据传输过程中，若终端设备100在核心网300的注册上下文正常，则终端设备100发送的请求能够收到网络侧的响应，终端设备100数据传输正常；若终端设备100在核心网300的注册上下文异常，则终端设备100发送的请求无法收到网络侧的响应，终端设备100数据传输异常。
基于此，当终端设备100数据传输异常时，终端设备100需要重新注册网络来更改在核心网300的注册上下文，以使其在核心网300的注册上下文恢复正常，进而使得数据传输恢复正常。
目前，终端设备100在侦测到数据传输异常时，先重新获取网络注册状态并重启数据开关，若仍侦测到数据传输异常，才重新注册网络，导致恢复数据传输异常耗费的时间较长。
因此，在本申请实施例中，终端设备100通过执行数据传输异常恢复方法来实现对数据传输异常的恢复。在该数据传输异常恢复方法中，终端设备100在数据连接处于激活状态时，启动数据传输异常侦测，若侦测到数据传输异常，则确定保护定时器是否处于运行状态，若保护定时器未处于运行状态，则启动保护定时器，并切换当前网络模式。其中，在侦测到数据传输异常且保护定时器未处于运行状态时，直接切换当前网络模式以实现重新注册网络，简化了恢复数据传输异常的步骤，使得数据传输异常恢复的时间缩短，同时，在保护定时器未处于运行状态时才切换当前网络模式，能够防止终端设备100频繁切换当前网络模式，进而避免终端设备100在恢复数据传输异常时频繁出现无服务状态，提高了用户体验。
具体地，请参阅图2，是本申请实施例提供的一种数据传输异常恢复方法的流程示意图，该数据传输异常恢复方法包括以下步骤。
S100：在数据连接处于激活状态时，启动数据传输异常侦测。
在本申请实施例中，当终端设备的数据开关开启，且终端设备与网络建立起对应的用户面数据承载通道时，终端设备的数据连接处于激活状态。在终端设备的数据连接处于激活状态时，终端设备能够实现数据传输，此时，对终端设备的数据传输状态进行侦测，能够准确确定终端设备的数据传输状态，因此，在数据连接处于激活状态时，启动数据传输异常侦测。
其中，启动数据传输异常侦测时，首先启动异常侦测定时器，该异常侦测定时器设置有第一预设时间；然后在异常侦测定时器计时结束时，统计第一预设时间内的发包数量和收包数量；最后根据第一预设时间内的发包数量和收包数量确定数据传输是否异常，若第一预设时间内的发包数量大于零且收包数量等于零，则确定数据传输异常，否则，确定数据传输未异常。
可以理解的是，在终端设备数据传输过程中，终端设备发送IP封包后，若能够得到网络侧的响应，则终端设备能够接收到网络侧返回的IP封包；若无法得到网络侧的响应，则终端设备无法接收到网络侧返回的IP封包。因此，若第一预设时间内的发包数量大于零且收包数量等于零，则确定终端设备在第一预设时间内发送的IP封包均无法得到网络侧的响应，确定数据传输异常。
其中，终端设备在第一预设时间内的发包数量和收包数量不为负整数。
S200：若数据传输异常，确定保护定时器是否处于运行状态。
S300：若保护定时器未处于运行状态，则启动保护定时器，并切换当前网络模式。
在本申请实施例中，保护定时器设置有第二预设时间，并且该第二预设时间大于第一预设时间。比如，第一预设时间设置为30s时，第二预设时间设置为300s。
该保护定时器用于使终端设备两次切换当前网络模式间隔至少第二预设时间，以防止终端设备频繁切换当前网络模式。优选地，该保护定时器为乒乓保护定时器。
在保护定时器未启动或者保护定时器计时结束时，确定保护定时器处于未运行状态；在保护定时器计时未结束时，确定保护定时器处于运行状态。
在本申请实施例中，网络模式包含网络通信类型，用于表征终端设备所支持的网络通信类型。比如，当网络模式包含的网络通信类型为2G、3G、4G和5G时，表征终端设备支持的网络通信类型为2G、3G、4G和5G；当网络模式包含的网络通信类型为2G、3G和4G时，表征终端设备支持的网络通信类型为2G、3G和4G。
在终端设备中存储有数量若干的预设网络模式，每个预设网络模式包含2G、3G、4G和5G中的至少一种网络通信类型，并且每个预设网络模式所包含的网络通信类型不同。
基于此，当切换当前网络模式时，在预设网络模式中选择与当前网络模式不同的任意一个网络模式作为目标网络模式，然后将当前网络模式切换为目标网络模式后，再将目标网络模式切换至当前网络模式。
由于切换当前网络模式亦即切换终端设备当前所支持的网络通信类型，因此，在将当前网络模式切换为与当前网络模式不同的目标网络模式后，终端设备当前所支持的网络通信类型改变，而终端设备当前所支持的网络通信类型发生改变后，终端设备需要在核心网中重新注册网络，因此，切换当前网络模式能够触发终端设备在核心网中重新注册网络。
在将当前网络模式切换为目标网络模式后，再将目标网络模式切换至当前网络模式，能够触发终端设备在核心网中进行两次重新注册网络，进一步保证恢复数据传输异常，并且能够使得终端设备所支持的网络通信类型回归用户最初设置的状态，提高用户体验。
可以理解的是，由于终端设备在重新注册网络时会处于无服务状态，因 此，在数据传输异常时，若直接切换当前网络模式以实现重新注册网络，则在数据传输频繁出现异常时，会导致终端设备频繁出现无服务状态，影响用户体验，因此，在数据传输异常时，确定保护定时器未处于运行状态时，才切换当前网络模式，以保证终端设备两次切换当前网络模式间隔至少第二预设时间，防止频繁切换当前网络模式；同时，启动保护定时器以保证终端设备下一次切换当前网络模式与此次切换当前网络模式间隔至少第二预设时间，防止频繁切换当前网络模式。
请参阅图3，在一些实施例中，为了实时侦测数据传输状态，在数据传输未异常时，重新启动数据传输异常侦测；或者，在保护定时器处于运行状态时，重新启动数据传输异常侦测；或者，在启动保护定时器并切换当前网络模式之后，重新启动数据传输异常侦测。
在本申请实施例中，在侦测到数据传输异常且保护定时器未处于运行状态时，直接切换当前网络模式以实现重新注册网络，简化了恢复数据传输异常的步骤，使得数据传输异常恢复的时间缩短，同时，在保护定时器未处于运行状态时才切换当前网络模式，能够防止终端设备频繁切换当前网络模式，进而避免终端设备频繁出现无服务状态，提高了用户体验。
进一步地，请参阅图4，是本申请实施例提供的一种数据传输异常恢复装置的结构示意图，该数据传输异常恢复装置应用于上述终端设备，并且该数据传输异常恢复装置各个模块的功能由上述终端设备执行，用于缩短恢复数据传输异常的时间，并避免在恢复数据传输异常时频繁出现无服务状态，提高用户体验。
值得注意的是，本申请实施例所使用的术语“模块”为可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置可以以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能被构想的。
具体地，该数据传输异常恢复装置包括。
启动模块110，用于在数据连接处于激活状态时，启动数据传输异常侦测；
确定模块120，用于在数据传输异常时，确定保护定时器是否处于运行状态；
处理模块130，用于在保护定时器未处于运行状态时，启动保护定时器，并切换当前网络模式。
在一些实施例中，处理模块130具体用于：在切换当前网络模式时，在预设网络模式中选择与当前网络模式不同的网络模式模式作为目标网络模式；将当前网络模式切换为目标网络模式后，再将目标网络模式切换至当前网络模式。
在一些实施例中，启动模块110具体用于：启动异常侦测定时器，异常侦测定时器设置有第一预设时间；在异常侦测定时器计时结束时，统计第一预设时间内的发包数量和收包数量；若发包数量大于零且收包数量等于零，则确定数据传输异常。
在一些实施例中，保护定时器设置有第二预设时间，第二预设时间大于第一预设时间。
在一些实施例中，启动模块110还用于：在数据传输未异常或保护定时器处于运行状态时，重新启动数据传输异常侦测。
由于装置实施例和方法实施例是基于同一构思，在内容不互相冲突的前提下，装置实施例的内容可以引用方法实施例的，在此不再一一赘述。
在本申请实施例中，在侦测到数据传输异常且保护定时器未处于运行状态时，直接切换当前网络模式以实现重新注册网络，简化了恢复数据传输异常的步骤，使得数据传输异常恢复的时间缩短，同时，在保护定时器未处于运行状态时才切换当前网络模式，能够防止终端设备频繁切换当前网络模式，进而避免终端设备频繁出现无服务状态，提高了用户体验。
