具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合实施例对本申请的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
目前，移动终端所处区域改变可能导致移动终端无法访问网络，进而导致网络数据丢失影响用户体验，基于此，本申请实施提供了一种网络数据的恢复方法、装置及移动终端，可以改善网络数据丢失的问题，有效提高了用户使用网络数据的体验。
为便于对本实施例进行理解，首先对本申请实施例所公开的一种网络数据的恢复方法进行详细介绍，该方法应用于移动终端，诸如应用于智能手机或平板电脑等设备，参见图1所示的一种网络数据的恢复方法的流程示意图，该方法主要包括以下步骤S102至步骤S106。
步骤S102，如果监听到移动终端所处区域发生改变，获取预先设置的载波组合优先级。
其中，载波组合优先级为移动终端支持的多个候选载波组合的优先级排序，候选载波组合可以用于访问网络，每个候选载波组合访问网络的速率不同，或者，多个候选载波组合中的至少部分候选载波组合访问网络的速率不同，移动终端将载波组合上报至网络后即可在该载波组合对应的速率范围内访问网络。移动终端所支持的候选载波组合可以根据移动终端的终端能力确定，终端能力可以包括移动终端连接网络的能力，诸如2G能力、3G能力、4G能力和5G能力中的一种或多种，如果移动终端的终端能力包括4G能力，表明移动终端可以连接4G网络。在实际应用中可以预先配置每种终端能力对应的CA组合(也即，上述载波组合)以及每个CA组合的优先级，得到候选载波组合优先级，并对移动终端进行跟踪以监听移动终端所处区域的变化，当移动终端从一个网络覆盖区域移动至另一个网络覆盖区域后，获取移动终端待访问的网络对应的候选载波组合优先级。
步骤S104，根据载波组合优先级确定目标载波组合。
在一种实施方式中，可以按照载波组合优先级从高到低的顺序，从多个候选载波组合中选取一个可以访问移动终端所处区域对应的网络的候选载波 组合，并将选取的候选载波组合确定为目标载波组合，其中，移动终端所处区域对应的网络也即上述待访问的网络。
步骤S106，基于目标载波组合访问移动终端所处区域对应的网络，用以恢复网络数据。
其中，网络数据可以理解为用户联网浏览的网页、视频或图像等数据。在实际应用中，移动终端将确定的目标载波组合上报至网络，并判断移动终端是否可以基于目标载波组合访问网络，若移动终端可以正常访问网络，则可以恢复移动终端所处区域改变前的网络数据。例如，移动终端通过4G网络浏览页面X，若监听到移动终端从4G网络覆盖区域A移动中另一个4G网络覆盖区域B，且移动终端所支持的4G网络对应的候选载波组合为组合1、组合2和组合3，按照载波组合优先级确定目标载波组合为组合1，则利用组合1访问区域B对应的4G网络，从而使用户可以继续浏览页面X，以实现网络数据的恢复。
本申请实施例提供的上述网络数据的恢复方法，在监听到移动终端所处区域改变后获取载波组合优先级，然后根据载波组合优先级确定目标载波组合，并基于目标载波组合访问移动终端所处区域对应的网络，以实现网络数据的恢复。上述方式在移动终端区域改变时，可以自适应地根据多个候选载波组合的优先排序确定访问网络所需的目标载波组合，基于目标载波组合访问网络以恢复网络数据，改善了网络数据丢失的问题，进而有效提高了用户使用网络数据的体验。
为了使移动终端可以保持较高的网络访问速率，可以在确定目标载波组合时应优先选择访问网络速率较高的候选载波组合，在此基础上，本申请实施例提供了一种载波组合优先级的设置方法，参见如下步骤1至步骤2。
步骤1，获取移动终端支持的多个候选载波组合。考虑到移动终端所支持的候选载波组合与移动终端所使用的运营商相关，因此在执行上述步骤1时，可以按照如下步骤1.1至步骤1.3获取移动终端支持的多个候选载波组合。
步骤1.1，确定移动终端所处区域对应的网络所属的运营商。在一种实施方式中，可以通过读取移动终端中放置的SIM(Subscriber Identity Module，用户身份识别)卡，确定移动终端所处区域对应的网络所属的运营商(诸如中国移动、中国电信或中国联通等)。
步骤1.2，获取针对运营商和移动终端的终端能力编写的载波代码。其中，载波代码可以用于表征移动终端所支持的载波组合。目前，同一个区域可能同时布设有多个运营商的网络，为使移动终端可以使用不同运营商的网络，可以针对终端能力和多个运营商分别编写载波代码，例如，在编写移动4G网络对应的载波代码时，由于CMCC(China Mobile Communications Corporation，中国移动)支持LTE B38、LTE B39和LTE B40等频段，配置上述频段对应的载波组合，并将配置的载波组合以载波代码形式写入移动终端中，用以在设置载波组合优先级时确定移动终端支持的多个候选载波组合，其中，移动4G网络表示运营商为移动且终端能力为4G能力。
步骤1.3，基于载波代码确定移动终端支持的多个候选载波组合。例如，若确定移动终端所处区域对应的4G网络属于中国移动，则获取移动4G网络对应的载波代码，从而确定移动终端支持的与移动4G网络对应的多个候选载波组合。
步骤2，基于各候选载波组合访问网络的速率的大小，对多个候选载波组合的优先等级进行排序，得到载波组合优先级。在一种实施方式中，可以使候选载波组合的优先等级与候选载波组合访问网络的速率呈正相关，也即，候选载波组合访问网络的速率越快，则其优先等级越高，如表1中所示的候选载波组合访问网络的速率，其中，表1中体现了移动终端支持的候选载波组合(UE DL Category)、在一个TTI(Transmit Time Interval，调度时间间隔)内可接收的最大DL-SCH(Downlink share channel，传输信道)传输块bit数、在一个TTI内可接收一个传输块的DL-SCH传输块最大bit数、软信道比特总数和支持下行空分复用的最大层数，基于表1中提供的数据可以计算得知 Category12和Category11的速率最高，因此设置与Category12相匹配的候选载波组合和与Category11相匹配的候选载波组合的优先等级最高，还可基于实际情况调整与Category12相匹配的候选载波组合和与Category11相匹配的候选载波组合各自的优先级。

考虑到移动终端若始终采用最大载波组合(也即，优先等级最高的候选载波组合)访问网络，可能存在最大载波组合与移动终端所处区域支持的载波组合不符的情况，例如，移动终端的最大载波组合为category20，而移动终端所处区域支持的载波组合为category18，此时将导致移动终端一直无法成功访问网络，因此在上述载波组合优先级的设置方法的基础上，本申请实施例进一步提供了一种根据载波组合优先级确定目标载波组合的可能实现方法，首先按照载波组合优先级由高至低的排列顺序，逐一将候选载波组合上报至网络，直至上报的候选载波组合与网络连接成功。例如，候选载波组合包括组合1、组合2、组合3和组合4等，且按照载波组合优先级由高至低得到排序为[组合1、组合2、组合3、组合4]，在一种可能的实施方式中，首先将组合1上报至网络，判断移动终端是否可以通过组合1与网络连接成功，若确定移动终端与网络连接成功，则将组合1确定为目标载波组合，若确定移动终端与网络连接失败，则将组合2上报至网络，直至上报的候选载波组合可以与网络连接成功，并将与网络连接成功的候选载波组合确定为目标载波组合。本申请实施例通过自适应地确定目标载波组合，可以在移动终端所处区域改变后快速可靠地连接网络，从而缓解了现有技术中因始终采用同一载波组合连网而导致的无法上网的情况。
为便于对上述步骤S106进行理解，本申请实施例在基于目标载波组合访问移动终端所处区域对应的网络时，可以确定与目标载波组合相匹配的网络category，进而基于网络category访问移动终端所处区域对应的网络。其中，网络category可以包括category20、category18、category16和category12等， 例如与候选载波组合1相匹配的网络category为category20、与候选载波组合2相匹配的网络category为category18、与候选载波组合3相匹配的网络category为category16、以及与候选载波组合4相匹配的网络category为category12，若目标载波组合为候选载波组合1，则可以基于category20访问移动终端所处区域对应的网络。
在上述实施例的基础上，本申请实施例提供了一种网络数据的恢复方法的可能应用示例，以手机连接4G网络为例，参见图2所示的另一种网络数据的恢复方法的流程示意图，该方法主要包括以下步骤S202至步骤S210。
步骤S202，手机注册4G网络，并将最大CA组合上报至4G网络。其中，最大CA组合也即前述优先等级最高的候选载波组合，例如，将category20上报至4G网络。
步骤S204，判断是否可以访问4G网络。如果是，执行步骤S210；如果否，执行步骤S206。在一种实施方式中，可以判断预设时长内的网速是否大于预设阈值，若网速大于预设阈值则确定可以访问4G网络；若网速小于预设阈值则确定无法访问4G网络。
步骤S206，手机按照预设的上报顺序调整CA组合。其中，上报顺序也即前述载波组合优先级。在一种实施方式中，可以基于载波组合访问网络的速率对上报顺序进行设置，也可以基于实际需求设置上报顺序。
步骤S208，手机将调整后的CA组合上报至4G网络，并执行步骤S204。例如，若category20无法访问网络，则将category18上报至4G网络，若category18仍无法访问网络，则将category16上报至4G网络，直至上报的CA组合可以访问网络。
步骤S210，手机基于上报的CA组合访问4G网络，以恢复网络数据。
为了使移动终端移动至网速较快的区域时，可以采用更快的网速访问网络，在每次监听到用户携带手机在多个网络覆盖区域间内移动时，均可以执行上述步骤S202至步骤S210调整目标载波组合。例如，手机位于区域1时 通过上述方法确定基于category16访问4G网络，当手机移动至区域2时，则按照上述方法先利用category20访问4G网络，如果区域2支持category20，则手机便可以使用更快的网速访问网络。
综上所述，本申请实施例在监听到移动终端所处区域改变后可以自适应地调整用于访问网络的CA组合，可以快速可靠地使移动终端与网络建立连接，从而恢复因区域改变而丢失的网络数据。而且，由于不同载波组合访问网络的速率不同，因此移动终端自适应调整访问网络的CA组合后，可以体验不同的网络访问速率，从而满足用户的不同速率需求。
