具体实施方式
随着LTE技术的日益成熟，移动终端的通信能力越来越强大，更多的频段得到移动终端的支持，甚至出现全频段移动终端。但是移动终端支持频段的增加可以扩大移动终端的适应范围，但同时也带来了一个问题。现有技术中，移动终端在手动搜网、漫游或第一次开机搜网等场景中，也就是移动终端无法从预先保存的历史记录频点中获取到能够用于当前网络注册的频点的场景中，会对自身支持的所有频段进行频段扫描以搜索用于当前网络注册的频点。然而，由于移动终端支持的频段越来越多，频段扫描速度也就会变得很慢，从而导致移动终端的入网速度很慢，影响用户体验。
例如，某移动终端支持band1，band2，band3，band4，band5，band7，band8，band12，band17，band18，band19，band20，band25，band26，band28， band29，band30，band38，band39，band40，band41，band66共22个按顺序排列的频段。需要说明的是，上述的band1，band2，band3等为频段号，根据LTE网络频段的划分规则，每个频段号均分别对应有一个频段。不管在哪个地域，该移动终端第一次开机搜网的时候都需要将所有的频段均扫描一遍。如果所处区域的通信网络支持的频段排在这些频段的最后面，例如，当前地域覆盖的通信网络的运营商为中国移动，中国移动支持的频段为：band38，band39，band40，band41。而这四个频段的在该移动终端支持的频段中的排列位置比较靠后，这样就需要花很多时间去先扫描当前网络不支持的频段，消耗很多不必要的时间。
鉴于此，本申请实施例提供了一种频段扫描方法及装置，应用于移动终端，以有效地提高移动终端频段扫描效率，减少频段扫描消耗的时间，提升用户体验。
图1示出了一种可应用于本申请实施例中的移动终端的结构框图。如图1所示，移动终端100包括：存储器102、存储控制器104、一个或多个(图中仅示出一个)处理器106、外设接口108、射频模块110。这些组件通过一条或多条通讯总线/信号线相互通讯。
存储器102用于存储软件程序以及模块，如本申请实施例中的频段扫描方法及装置对应的程序指令/模块，处理器106通过运行存储在存储器102内的软件程序以及模块，从而执行各种功能应用以及数据处理，如本申请实施例提供的频段扫描方法。存储器102可包括高速随机存储器，还可包括非易失性存储器，如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。处理器106以及其他可能的组件对存储器102的访问可在存储控制器104的控制下进行。
外设接口108将各种输入/输出装置耦合至处理器106以及存储器102。在一些实施例中，外设接口108，处理器106以及存储控制器104可以在单 个芯片中实现。在其他一些实例中，他们可以分别由独立的芯片实现。
射频模块110用于接收以及发送电磁波，实现电磁波与电信号的相互转换，从而与通讯网络或者其他设备进行通讯。
可以理解，图1所示的结构仅为示意，移动终端100还可包括比图1中所示更多或者更少的组件，或者具有与图1所示不同的配置。图1中所示的各组件可以采用硬件、软件或其组合实现。
本实施例中涉及的移动终端100，可以包括智能手机、平板电脑、电子书阅读器、动态影像专家压缩标准音频层面3(Moving Picture Experts Group Audio Layer III，MP3播放器)、动态影像专家压缩标准音频层面4(Moving Picture Experts Group Audio Layer IV，MP4)播放器、膝上型便携计算机、车载电脑、穿戴式移动终端等等。
下面将结合本申请实施例中附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。通常在此处附图中描述和示出的本申请实施例的组件可以以各种不同的配置来布置和设计。因此，以下对在附图中提供的本申请的实施例的详细描述并非旨在限制要求保护的本申请的范围，而是仅仅表示本申请的选定实施例。基于本申请的实施例，本领域技术人员在没有做出创造性劳动的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。
第一实施例
图2示出了本申请第一实施例提供的一种频段扫描方法的流程图。本实施例提供的频段扫描方法应用于移动终端100。请参阅图2，所述方法包括：
步骤S110，获取所述移动终端的当前通信网络，根据所述当前通信网络获取第一运营商数据，所述第一运营商数据包括：第一运营商信息和所 述第一运营商信息支持的网络频段信息；
本实施例中，当前通信网络具体为移动终端100当前所在的地域覆盖的移动通信网络。当前通信网络对应的运营商信息可以为一个，也可以为多个。例如，移动终端100当前所在的地域同时被中国移动和中国联通对应的通信网络覆盖，此时，第一运营商信息则包括中国移动对应的运营商信息和中国联通对应的运营商信息。
根据当前通信网络获取第一运营商数据的实施方式可以为：根据当前通信网络获取第一运营商信息，根据第一运营商信息获取第一运营商信息对应的第一运营商支持的网络频段信息。
本实施例中，运营商信息可以是运营商的名称。此时，获取第一运营商信息的方式可以为：移动终端100根据当前网络下发的消息获取当前所在网络的网络标识信息，将得到的网络标识信息与预设的运营商名称表中存储的网络标识信息进行匹配，并获得匹配成功项对应的运营商名称。运营商名称表中包括运营商名称以及与该运营商对应的网络标识信息。例如，移动终端100接收当前所在网络下发的扩展系统参数消息，并从该消息中提取网络标识信息。其中，网络标识信息可以包括：移动国家码(Mobile Country Code，MCC)和移动网络号码(Mobile Network Code，MNC)。
或者，运营商信息也可以是运营商对应的唯一标识码。例如，该唯一标识码可以包括上述的网络标识信息。
根据第一运营商信息获取第一运营商信息对应的第一运营商支持的网络频段信息的方式可以为：移动终端中预先存储有运营商支持频段表，运营商支持频段表中包括各个运营商对应的运营商信息以及其支持的网络频段信息；根据第一运营商信息查找该运营商支持频段表，即可以获取到第一运营商信息对应的第一运营商支持的网络频段信息。
步骤S120，根据所述第一运营商数据以及所述移动终端支持的频段得 到待选频段；
于本步骤中，移动终端100支持的频段为移动终端100自身所支持的频段。例如，对于支持LTE网络的移动终端100，移动终端100支持的LTE频段可以包括：band1，band2，band3，band4，band5，band7，band8，band12，band17，band18，band19，band20，band25，band26，band28，band29，band30，band38，band39，band40，band41，band66。当然，移动终端100也可以支持所有的LTE网络频段。
第一运营商数据包括第一运营商信息和该第一运营商信息支持的网络频段信息。作为一种实施方式，根据所述第一运营商数据以及所述移动终端支持的频段得到待选频段具体可以包括：根据第一运营商信息获取第一运营商信息对应的第一运营商支持的频段；获取移动终端100支持的频段；对比第一运营商支持的频段和移动终端100支持的频段，得到第一运营商和移动终端100均支持的频段，将该均支持的频段作为待选频段。本实施例中，第一运营商支持的频段以及移动终端100支持的频段可以预先存储于移动终端100中，此时，根据存储路径以及索引即可以查找并获得第一运营商支持的频段以及移动终端100支持的频段。具体的，查找第一运营商支持的频段的索引可以为第一运营商信息，查找移动终端100支持的频段的索引可以为移动终端100对应的唯一身份标识。
需要说明的是，当移动终端100支持全频段时，第一运营商支持的频段即为待选频段。
通过上述方式筛选出当前通信网络和移动终端100均支持的频段作为待选频段，能够有效地避免移动终端100在进行频段扫描时对当前通信网络不支持的频段进行扫描，有利于减少频段扫描消耗的时间，进而减少移动终端100在手动搜网、漫游或第一次开机搜网等场景进行网络注册所消耗的时间。
此外，作为另一种实施方式，当移动终端100需要通过用户身份识别卡(Subscriber Identification Module，SIM)接入移动通信网络时，例如，移动终端100为智能手机时，为了进一步减小频段扫描消耗的时间，提高移动终端100在第一次开机搜网、手动搜网或漫游等应用场景中的入网速度，本申请实施例除了考虑当前通信网络支持的频段外，还考虑了SIM卡的配置。此时，步骤S120具体可以为：根据第一运营商信息支持的网络频段信息、移动终端100支持的频段以及预先获取的第二运营商信息支持的网络频段信息得到待选频段，其中，第二运营商信息为移动终端100的SIM卡对应的运营商信息。
此时，如图3所示，步骤S120可以包括：
步骤S121，判断第一运营商信息和预先获取的第二运营商信息是否匹配；
可以理解的是，预先获取的第二运营商信息是指在执行步骤S121之前，需要先获取第二运营商信息，第二运营商信息为移动终端100中插入的SIM卡对应的运营商信息。SIM卡中存储有识别码，移动终端100可以读取SIM卡中存储的识别码，根据所读取的识别码获得SIM卡对应的运营商信息，将该运营商信息作为第二运营商信息。例如，SIM卡中存储的识别码为国际移动用户识别码(International Mobile Subscriber Identification Number，IMSI)。IMSI由MCC、MNC和移动用户识别号码(Mobile Subscriber Identification Number，MSIN)组成。其中，MCC用于唯一地识别移动客户所属的国家，例如，中国的MCC为460。MNC用于识别移动客户所归属的移动网络，例如，中国移动为00，中国联通为01，中国电信为03。MSIN用于识别某一移动通信网中的移动用户。此时，第二运营商信息可以包括MCC和MNC，或者是，根据MCC、MNC以及预设的运营商名称表得到的运营商名称。
本实施例中，判断第一运营商信息和预先获取的第二运营商信息是否匹配的方式为判断第一运营商信息中是否存在与第二运营商信息一致的运营商信息。可以理解的是，具体应用中，上述第一运营商信息可以包括一个运营商信息，也可以包括多个运营商信息。当第一运营商信息仅包括一个运营商信息时，该第一运营商信息与第二运营商信息一致，例如均为中国移动对应的运营商信息，则表示第一运营商信息和第二运营商信息匹配。当第一运营商信息包括多个运营商信息时，若这些运营商信息中只要存在一个运营商信息与第二运营商信息一致，则表示第一运营商信息与第二运营商信息匹配，若第一运营商信息包括的多个运营商信息均与第二运营商不一致，则表示第一运营商信息与第二运营商信息不匹配。
当第一运营商信息和预先获取的第二运营商信息不匹配时，执行步骤S122，并在执行完步骤S122后继续执行步骤S123。当第一运营商信息和预先获取的第二运营商信息匹配时，执行步骤S124。
步骤S122，根据第一运营商信息以及第二运营商信息获取授权频段；
其中，第二运营商信息为移动终端100的SIM卡对应的运营商信息。授权频段为第一运营商信息对应的运营商与第二运营商信息对应的运营商约定的频段。例如，授权频段可以为第一运营商信息对应的第一运营商与第二运营商信息对应的第二运营商预先签订的漫游协议中，第一运营商授权给第二运营商使用的频段。本实施例中，各个运营商之间的授权频段可以预先存储于移动终端100中，根据第一运营商信息以及第二运营商信息可以从预先存储的授权频段中查找到第一运营商和第二运营商对应的授权频段。
需要说明的是，当第一运营商包括多个运营商时，第一运营商授权给第二运营商使用的频段包括第一运营商包括的每个运营商授权给第二运营商使用的频段。例如，当第一运营商包括运营商A和运营商B，第二运营 商为运营商C时，步骤S122所获取到的授权频段应该为运营商A授权给运营商C使用的频段和运营商B授权给运营商C使用的频段。
具体的，上述授权频段可以以对应表的形式存储，并以运营商信息作为查表索引。此时，步骤S122可以为：根据第一运营商信息以及第二运营商信息在预设的第一对应表中查找，得到授权频段。此时所得到的授权频段为第一运营商授权给第二运营商使用的频段。
步骤S123，对比授权频段与移动终端支持的频段，得到移动终端支持的授权频段，将该授权频段作为待选频段。
从步骤S122中得到的授权频段中选取移动终端100支持的频段作为待选频段。例如，将步骤S122中得到的授权频段作为第一集合，将移动终端100支持的频段作为第二集合，计算第一集合和第二集合之间的交集，该交集中的频段即为移动终端100支持的授权频段。
步骤S124，获取移动终端与第二运营商均支持的频段，将该频段作为待选频段。
其中，第二运营商为第二运营商信息对应的运营商。当第一运营商信息和第二运营商信息匹配时，说明第一运营商信息对应的第一运营商中，存在与第二运营商信息对应的第二运营商一致的运营商。此时，可以从第二运营商信息对应的第二运营商支持的频段中，选取移动终端100也支持的频段作为待选频段。
具体的，步骤S124可以包括：查找预设的第二对应表，获取第二运营商支持的频段；对比移动终端100支持的频段和第二运营商支持的频段，得到移动终端100与第二运营商均支持的频段，将该频段作为待选频段。其中，第二对应表中包括各个运营商支持的频段。例如，查找第二对应表获取到第二运营商支持的频段为：band34，band38，band39，band40，band41；而移动终端100支持的频段为：band1，band2，band3，band4，band5，band7， band8，band12，band17，band18，band19，band20，band25，band26，band28，band29，band30，band38，band39，band40，band41，band66。则将band38，band39，band40，band41作为待选频段。
本实施例中，第二对应表可以根据需要，收集现有运营商所支持的频段设置。例如，第二对应表可以为如表1所示的对应表。表1中，第一列表示各个国家的运营商，例如，美国(AT&T)表示美国的运营商AT&T，加拿大表示加拿大的运营商。第二列表示对应运营商支持的LTE网络频段。
表1
Figure PCTCN2018088396-appb-000001
需要说明的是，第一对应表和第二对应表的具体内容可以根据需要设置。本实施例中，上述的第二对应表与第一对应表可以是同一个对应表， 该对应表中既可以查找到相关运营商支持的频段，也可以查找到不同运营商之间约定的授权频段。或者，上述的第二对应表与第一对应表也可以是相互独立的两个对应表。
步骤S130，对所述待选频段进行扫描，得到用于网络注册的目标频点。
本实施例中，当待选频段包括多个频段时，可以优选将这些频段按照预先设置的扫描顺序排列，然后按照该顺序对待选频段中的每个频段进行扫描，得到用于网络注册的目标频点。其中，预先设置的扫描顺序可以根据需要设置。例如，预先设置的扫描顺序可以为频段号由小到大的顺序。
具体的，步骤S130可以为：先对待选频段的预选频点进行粗扫描得到有效频段，然后再对有效频段中的各个频点进行细扫描得到目标频点。
作为一种实施方式，预选频点可以是每个待选频段的中心频点，此时，对待选频段的预选频点进行粗扫描得到有效频段的具体方法可以为：按照预先设置的扫描顺序对每个待选频段进行扫描，获取每个待选频段的中心频点的接收信号强度；将该待选频段的中心频点的接收信号强度与预设阈值进行比较，当该待选频段的中心频点的接收信号强度大于或等于预设阈值时，判定该待选频段为有效频段。其中，预设阈值可以根据需要设置。对所有待选频段均进行上述粗扫描后，即可从待选频段中进一步筛选出有效频段。
其中，获取每个待选频段的中心频点的方式可以为：移动终端100中预先存储有每个频段的中心频点，此时，可以通过查找的方式得到每个待选频段的中心频点。或者，也可以根据每个待选频段的上限频率、下限频率以及预设的中心频点计算公式计算得到每个待选频段的中心频点。
作为另一种具体实施方式，预选频点可以是按照预设的第一扫描间隔对每个待选频段进行采样得到的频点。此时，对待选频段的预选频点进行粗扫描得到有效频段的具体方法还可以为：按照预设的扫描顺序和预设的 第一扫描间隔对每个待选频段进行频点扫描，得到该待选频段中多个第一扫描频点的接收信号强度；分别将这些第一扫描频点的接收信号强度与预设阈值进行比较，当存在第一扫描频点的接收信号强度大于或等于预设阈值时，判定该待选频段为有效频段。其中，第一扫描间隔可以根据需要设置。
具体的，对有效频段中的各个频点进行细扫描得到目标频点的方法可以为：按照预设的第二扫描间隔对上述粗扫描过程筛选出的每个有效频段进行频点扫描，得到该有效频段中多个第二扫描频点的接收信号强度；分别将这些第二扫描频点的接收信号强度与预设阈值进行比较，判定接收信号强度大于或等于预设阈值的扫描频点为有效频点；记录该有效频点以及该有效频点对应的接收信号强度。对所有有效频段进行上述细扫描后，即可从有效频段中进一步筛选出有效频点。比较这些有效频点对应的接收信号强度，选取接收信号强度最大的有效频点作为用于网络注册的目标频点。其中，第二扫描间隔也可以根据需要设置，且第一扫描间隔大于第二扫描间隔。
此外，对有效频段中的各个频点进行细扫描得到目标频点的方法还可以为：按照预设的第二扫描间隔对上述粗扫描过程筛选出的每个有效频段进行频点扫描，分别得到每个有效频段中多个第二扫描频点的接收信号强度；然后比较各个有效频段对应的第二扫描频点的接收信号强度，选取接收信号强度最大的第二扫描频点作为用于网络注册的目标频点。
综上所述，本申请实施例提供的频段扫描方法通过第一运营商数据以及移动终端100支持的频段得到待选频段，再对待选频段进行扫描得到目标频点，能够有效地提高移动终端100的频段扫描效率，减少频段扫描所消耗的时间，进而减少移动终端100的网络注册时间。
