Description

一种搜网方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种搜网方法及装置。
背景技术
公共陆地移动网络(PLMN，Public Land Mobile Network)，由政府或它所批准的经营者，为公众提供陆地移动通信业务目的而建立和经营的网络。该网络通常与公众交换电话网互连，形成整个地区或国家规模的通信网。PLMN的网络标识通常是一串数字码，例如中国移动的PLMN的网络标识为46000，中国联通的PLMN的网络标识为46001等。
随着人们生活水平的提高，携带终端设备(如手机)出国旅游或出差办事的用户也越来越多，当用户进行漫游通信(如国际漫游通信)时，其终端设备等需要重新找网，以接入到当地网络进行正常通信。例如，当终端设备从归属地移动到拜访地(例如终端设备从归属国漫游至拜访国)，终端设备需要接入到当前归属地的公共陆地移动网络PLMN，然而，目前经常发生的情况是终端设备从某归属地移动到拜访地，终端设备经常需要很长的时间才可成功接入当前拜访地的公共陆地移动网络，这极大的影响用户通信体验。
针对以上技术问题，现有技术中的一些解决方案是通过在终端设备的等效PLMN(Equivalent PLMN，EPLMN)列表中预先存储一些漫游国家的PLMN，以将拜访地(漫游国家)的PLMN与归属地(本地)的PLMN进行等效，以加快搜网速度，但是由于目前协议中EPLMN列表中只能存放固定数量(通常是16个)PLMN的网络标识，因此很有可能导致在一些国际漫游场景中，需要等效的PLMN的网络标识没有预先存储或者是没有空间存储在该EPLMN列表中，从而无法进行等效搜网，最终致使终端设备搜网效率低，用户体验差。

以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、终端设备，又称之为用户设备(User Equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，如具有无线连接功能的手持式设备、车载设备等。常见的终端设备例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(Mobile Internet Device，MID)、可穿戴设备、智能手环、计步器、MP3播放器(Moving Picture Experts Group Audio Layer III，动态影像 专家压缩标准音频层面3)、MP4(Moving Picture Experts Group Audio Layer IV，动态影像专家压缩标准音频层面3)播放器、个人数字助理(Personal Digital Assistant，PDA)和膝上型便携计算机等。

图1是本申请实施例提供的一种搜网方法的流程示意图，下面将结合附图1从终端设备侧对本申请实施例中的一种搜网方法进行详细介绍，该方法包括以下步骤S101-步骤S103。
步骤S101：在终端设备开机后或者处于无服务状态的情况下，获取当前搜索到的公共陆地移动网络PLMN的网络标识中的第一移动国家码MCC。
具体地，终端设备或者终端设备中的相关处理器或者相关处理模块(后续相同不再赘述)在终端设备开机后或者处于无服务状态的情况下，获取当前搜索到的公共陆地移动网络PLMN的网络标识中的第一移动国家码MCC。因为， 在本申请中获取当前搜索到的PLMN的网络标识中的第一MCC的目的在于确定终端设备当前具体处于哪个国家，进而根据确定的国家精确搜索该国家对应的PLMN，以避免盲目搜索其它不相关的网络，从而导致搜网速度慢。而其中如何确定当前搜索到的PLMN，可选地，可以将当前搜索到的最强信号的PLMN，也可以将当前最快搜索到的PLMN，还可以将搜索到的所有PLMN中出现次数最多的MCC对应的PLMN确定为所述当前搜索到的PLMN。
步骤S102：根据所述第一MCC从第一预置列表中获取与所述第一MCC对应的第一国家的PLMN的网络标识。
具体地，由于PLMN＝MCC+MNC，例如中国移动的PLMN为46000，中国联通的PLMN为46001。因此可以根据PLMN的网络标识中的MCC来判定该PLMN对应的国家，即同一个国家的MCC一定是相同的。所以在经过步骤S101中确认了终端设备的第一MCC后可以进一步确定该第一MCC对应的第一国家。并且由于本申请中提供的第一预置列表中包括多个国家的PLMN的网络标识，因此终端设备可以根据该第一预置列表获取该第一国家对应的所有PLMN。可以理解的是，第一预置列表中可以存放所有国家的PLMN的网络标识，也可以只存放多个热门国家的PLMN的网络标识，例如，旅游热门国家，出差热门国家。可选地，第一预置列表中存储的为与所述终端设备中所插入的用户身份识别卡进行了签约的PLMN，即第一国家的PLMN的网络标识可以是指该第一国家的所有PLMN的网络标识，也可以是指与终端设备中所插入的用户身份识别卡进行了签约的PLMN的网络标识。
在确定了第一MCC之后，就需要在第一预置列表中找出所有PLMN的网络标识中包含的MCC为第一MCC的PLMN，并确定为第一国家的PLMN的网络标识。例如，假设第一MCC为460，那么对应的第一国家就为中国，而第一国家的PLMN的网络标识，就包括中国移动(PLMN为46000,46002等)，中国联通(46001,46007等)和中国电信(46006等)。假设第一MCC为310，则第一国家为美国。
在一种可能的实现方式中，所述获取当前搜索到的公共陆地移动网络PLMN的网络标识中的第一移动国家码MCC，包括：获取当前最快搜索到的 PLMN的网络标识中的第一MCC；或者获取当前搜索到的信号最强的PLMN的网络标识中的第一MCC，或者是根据相关算法计算得到的终端设备当前最大可能性所在的国家对应的第一MCC，本申请对此不作具体限定。
在一种可能的实现方式中，所述第一预置列表中的所述多个国家的PLMN的网络标识按照MCC的不同进行分类存储，即MCC相同的PLMN放置在一起，便于查找获取的时候更加快速精准，提高查表效率。可选地，多个国家之间的PLMM的网络标识可以根据MCC的数字大小进行顺序排列，进一步便于查找。
在一种可能的实现方式中，所述EPLMN列表或者EHPLMN列表中默认存储所述终端设备已经签约的预设国家的PLMN的网络标识。即在没有更新EPLMN列表之前，可以在EPLMN列表或者EHPLMN列表中默认存储一些热门的与终端设备进行签约的国家的PLMN。
在一种可能的实现方式中，本申请中的第一预置列表中存储的各个国家的PLMN可以是针对不同的终端设备(本质上是插入了不同的运营商的用户身份识别卡，或插入了同一运营商开通了不同业务的用户身份识别卡的终端设备)量身定制的第一预置列表，并且第一预置列表中存储的各个国家的PLMN也可以根据实际情况实时更新，以保证终端设备搜网的准确性和高效性。
步骤S103：将获取的所述第一国家的PLMN的网络标识更新至所述终端设备的等效公共陆地移动网络EPLMN列表和/或等效本地公共陆地移动网络EHPLMN列表中，并根据更新后的所述EPLMN列表和/或所述EHPLMN列表进行搜网。
具体地，由于根据现有技术中的PLMN列表的搜网优先级，终端设备开机后或者无服务时，一般会首先搜索RPLMN，如果RPLMN搜索失败，则会根据对应的EPLMN或者EHPLMN进行搜网。即若当前EPLMN列表和/或EHPLMN列表中没有存储所达到的漫游国家的PLMN，则会导致无法进行等效搜网。因此，在确定了终端设备当前所处于的具体国家后，则可以将该国家对应的PLMN更新至终端设备的EPLMN列表和/或EHPLMN列表中进行等效，以便于快速搜网。即本申请将获取的第一国家的PLMN的网络标识更新 到终端设备的EPLMN列表和/或EHPLMN列表中进行等效，如此一来，由于EPLMN或EHPLMN列表中的PLMN与RPLMN是等效的，因此可以以更精准更小的搜索范围进行搜网，便可以快速的驻留到该第一国家。需要强调的是，本申请中的将获取的第一国家的PLMN的网络标识更新至终端设备的EPLMN列表和/或EHPLMN列表中，是指将第一国家的PLMN替换覆盖掉EPLMN列表和/或EHPLMN列表中本来存放的PLMN的网络标识，即每次更新后，EPLMN列表和/或EHPLMN列表中默认的或者上一次更新的PLMN的网络标识就不复存在了，只保留当前所更新的PLMN的网络标识。
进一步地，终端设备根据第一MCC从第二预置列表中获取与第一MCC对应的第一国家的禁用公共陆地移动网络FPLMN(Forbidden PLMN)的网络标识，其中，第二预置列表中包括终端设备中当前所插入的用户身份识别卡所对应的多个国家的FPLMN的网络标识；将获取的第一国家的FPLMN的网络标识更新至终端设备的FPLMN列表中。即本申请中除了可以更新EPLMN以外，还可以更新终端设备的FPLMN，由于FPLMN为被禁止访问的PLMN，通常终端在尝试接入某个PLMN被拒绝以后，会将其加到本列表中。本申请中的第二预置列表中预先存储了终端设备中所插入的用户身份识别卡对应的在各个国家所禁用的PLMN，因此可以在根据第一MCC判断出当前所在的国家后，快速的从第二预置列表中获取该用户身份识别卡在该第一国家中对应的无法使用的FPLMN的网络标识，再将其更新到终端设备的FPLMN列表中，便于终端设备快速的获知哪些网络无法使用，即在搜网时避免搜索该网络，从而进一步地节省搜网时间，加快入网效率。
再进一步地，终端设备根据第一MCC从第三预置列表中获取与第一MCC对应的第一国家的优选公共陆地移动网络PPLMN(preference PLMN)的网络标识，其中，第三预置列表中包括终端设备中当前所插入的用户身份识别卡所对应的多个国家的PPLMN的网络标识；将获取的第一国家的PPLMN的网络标识更新至终端设备的PPLMN列表中。即本申请中除了可以更新EPLMN和/或FPLMN以外，还可以更新终端设备的PPLMN，由于PPLMN为优选的PLMN，通常是终端设备搜网优先级最高的网络。本申请中的第三预置列表中 预先存储了终端设备中所插入的用户身份识别卡对应的在各个国家所优先搜索的PLMN，因此可以在根据第一MCC判断出当前所在的国家后，快速的从第三预置列表中获取该用户身份识别卡在该第一国家中对应的优先搜索的PPLMN的网络标识，再将其更新到终端设备的PPLMN列表中，便于终端设备快速的搜网过程中，可以优先搜索PPLMN，从而进一步地节省搜网时间，加快入网效率。
需要说明的是，对于一个终端设备来说，通常需要维护几种不同类型的PLMN列表，每个列表中会有多个PLMN。但是，目前根据协议规定，EPLMN列表中只能存放16个PLMN的网络标识，若终端设备经常需要在多个国家之间进行漫游，那么EPLMN列表和/或EHPLMN列表中的PLMN需要经常更新，或者在某些情况下，无法及时获取终端设备所需要的PLMN进行等效，所以终端设备在漫游时不能使用准确有效的签约的PLMN进行漫游地的进行等效搜网，导致搜网速度慢。
而本申请实施例，通过在终端设备开机后或者处于无服务状态的情况下，获取当前搜索到的公共陆地移动网络PLMN的网络标识中的第一移动国家码MCC；并根据所述第一MCC从第一预置列表中获取与所述第一MCC对应的第一国家的PLMN的网络标识；最终将获取的所述第一国家的PLMN的网络标识更新至所述终端设备的等效公共陆地移动网络EPLMN列表和/或等效本地公共陆地移动网络EHPLMN列表中，并根据更新后的所述EPLMN列表和/或所述EHPLMN列表进行搜网。即本申请在第一预置列表中存放多个国家的PLMN，在根据当前搜索到的PLMN的网络标识中的MCC确定终端设备当前所在的国家后，便在第一预置列表中获取该所在国家对应的PLMN，并将该国家对应的PLMN更新到该终端设备的EPLMN列表中进行等效，便于终端设备根据该EPLMN列表进行搜网，加快搜网效率。本申请可以解决终端设备在根据EPLMN列表和/或EHPLMN列表进行等效搜网过程中可能存在的等效网络不准确或者等效网络不全面导致的搜网效率较低的问题，提升用户通信体验。
图2是本申请实施例提供的另一种搜网方法的流程示意图，下面将结合附图2从终端设备侧对本申请实施例中的另一种搜网方法进行详细介绍，如图2所示，该方法可以包括以下步骤S201-步骤S207。
步骤S201：在终端设备开机后或者处于无服务状态的情况下，获取所述终端设备的已登记公共陆地移动网络RPLMN的网络标识中的第二MCC。
具体地，在终端设备开机后或者处于无服务状态的情况下，也可以首先获取RPLMN的网络标识中第二MCC。也就是说，由于移动的连续性或者说用户到达一个漫游国家后通常会停留较长的一端时间，因此，在部分场景中，终端设备很有可能还处在上一个注册网络对应的国家，所以可以优先考虑判定终端设备处在RPLMN的网络标识中的第二MCC对应的国家。
步骤S202：根据所述第二MCC从第一预置列表中获取与所述第二MCC对应的第二国家的PLMN的网络标识；
具体地，同理也获取第二MCC在第一预置列表中对应的所有PLMN的网络标识。更具体地可以参照步骤S102，此处不再赘述。
步骤S203：将获取的所述第二国家的PLMN的网络标识更新至所述终端设备的EPLMN列表和/或EHPLMN列表中，并根据更新后的所述EPLMN列表和/或所述EHPLMN列表进行搜网。
具体地，同理也将第二MCC对应的所有PLMN的网络标识更新到EPLMN中。更具体地可以参照步骤S102，此处不再赘述。
需要说明的是，假设在经过上述步骤S201-步骤S203的搜网步骤，已经搜网并注册成功，则可以开始正常通信。即不会出现后续步骤的处于无服务状态的情况，也即是不会执行后续步骤S204-步骤S206。如果经过上述步骤S201-步骤S203的搜网，仍然还是处于无服务状态，则可以确定当前根据RPLMN的网络标识确定的第二MCC有误，即对当前终端设备所处于的具体国家判断有误，因此需要重新判断。因此可以继续执行步骤S204-步骤S206。或者，在经过上述搜网之后，又进行了重新开机，也可以继续执行步骤S204-步骤S206。
步骤S204：在终端设备开机后或者处于无服务状态的情况下，获取当前搜索到的公共陆地移动网络PLMN的网络标识中的第一移动国家码MCC。
步骤S205：根据所述第一MCC从第一预置列表中获取与所述第一MCC对应的第一国家的PLMN的网络标识，其中，所述第一预置列表中包括多个国家的PLMN的网络标识。
步骤S206：将获取的所述第一国家的PLMN的网络标识更新至所述终端设备的等效公共陆地移动网络EPLMN列表和/或等效本地公共陆地移动网络EHPLMN列表中，并根据更新后的所述EPLMN列表和/或所述EHPLMN列表进行搜网。
具体地，步骤S204至步骤S206可参考上述图1实施例中的步骤S101至步骤S103，这里不再赘述。
步骤S207：在所述终端设备入网成功的情况下，将接入成功的PLMN的等效PLMN的网络标识更新至所述EPLMN列表和/或所述EHPLMN列表中进行等效。
具体地，由于前述根据第一MCC或者第二MCC获取的第一预置列表中的对应的PLMN是属于对应国家的全部PLMN，或者是与终端设备中的用户身份识别卡进行签约的PLMN，范围比较大。而最终终端设备只会注册到某一个网络上，因此，此时EPLMN列表和/或EHPLMN列表中更新的PLMN对当前的终端设备来说范围较大。因此，可以在终端设备确定注册上某个网络之后，将成功接入的PLMN的真正等效PLMN更新到EPLMN列表和/或EHPLMN列表中，也即是说此时EPLMN列表和/或EHPLMN列表中更新存放的是范围更为确定而精准的等效网络，便于终端设备在成功注册了某个网络之后，能在该网络的等效网络范围内，进行正常通信。
可以理解的是，本申请中的更新终端设备的EPLMN列表和/或EHPLMN列表，可以理解为一个灵活且根据终端设备的实际情况而实时变化的更新过程，即根据终端设备当前是否有服务，或者当前是否已经成功注册网络，或者是否是刚开机等具体场景来有目的性的精确EPLMN或EHPLMN中的等效PLMN的范围，实时保证终端设备在漫游国家甚至是归属国家搜网的高效性。
在具体的应用场景中，如图3所示，图3是本发明实施例中搜网方法的一个具体应用场景示意图，现有技术中当终端设备漫游到其它国家可能会搜网速 度慢，甚至可能会出现图3中左图所示的连接超时的情况，但是应用了本申请实施例之后，就可以实现图3中右图所示的快速搜网并注册。更具体地，请参见上述方法实施例的说明。
本申请实施例，除了保留了图1对应的实施例中的有益效果。还进一步地通过优先考虑将RPLMN中的MCC对应的国家确定为终端设备当前所在的国家，进而将该国家的PLMN更新到终端设备的EPLMN列表和/或EHPLMN列表中进行等效，可以在终端设备当前没有更换漫游国家的情况下进一步的加快搜网速度。
