Description

一种网络接入方法及移动通信终端
本发明要求2015年4月30日递交的发明名称为“一种网络接入方法及移动通信终端”的申请号201510221780.7的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明涉及移动通讯技术领域，尤其涉及一种网络接入方法及移动通信终端。
背景技术
公共陆地移动网络(Public Land Mobile Network，PLMN)是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。该网络必须与公众交换电话网络(Public Switched Telephone Network，PSTN)互连，形成整个地区或国家规模的通信网。在用户进行漫游时，其移动通信终端设备如手机等需要重新进行找网，以获取公共陆地移动网信息。
目前，大部分移动通信终端在开机时，会优先搜索已登记公共陆地移动网络(Registered Public Land Mobile Network，RPLMN)，然后才选择归属地公共陆地移动网络(Home Public Land Mobile Network，HPLMN)、等效归属地公共陆地移动网络(Equivalent Home Public Land Mobile Network，EHPLMN)或者拜访地公共陆地移动网络(Visited Public Land Mobile Network，VPLMN)。当移动通信终端漫游至其它国家第一次开机时，移动通信终端并不知道自己处于漫游状态，会默认搜索已登记公共陆地移动网络RPLMN，由于当前漫游国家并不存在该已登记公共陆地移动网络RPLMN，因而导致找网失败。当移动通信终端到第二次进入该地进行网络搜索时，手机依然会继续搜索已登记公共陆地移动网络RPLMN，导致再次找网失败，浪费了网络搜索时间，而且大大地降低了网络接入的效率。

公共陆地移动网络PLMN是一个无线通讯系统，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。该网路通常与公众交换电话网络PSTN互连，形成整个地区或国家规模的通信网。公共陆地移动网络PLMN包括以下几种类型：
(1)已登记公共陆地移动网络RPLMN：是移动通信终端在上次关机或脱网前登记上的PLMN。

下面将结合附图1-附图2，对本发明实施例提供的网络接入方法进行详细介绍。
请参阅图1，为本发明实施例提供的一种网络接入方法的流程示意图，该方法包括以下步骤。
步骤S101，当移动通信终端的网络记录文件中不存在当前拜访地公共陆地移动网络标识时，获取所述当前拜访地公共陆地移动网络标识并存储至所述移动通信终端的网络记录文件内。
具体实现中，移动通信终端的网络记录文件是指移动通信终端中用于记录网络标识信息的文件，如加密文件系统(Embedded File System,EFS)。当携带该移动通信终端的用户首次来到某拜访地时，移动通信终端的网络记录文件中没有该拜访地的记录，即不存在该拜访地公共陆地移动网络VPLMN标识，则需要通过将该拜访地公共陆地移动网络VPLMN标识添加至移动通信终端的网络记录文件中，以备该携带该移动通信终端的用户第二次或后期多次来到该拜访地时，可根据读取该网络记录文件，获取拜访地公共陆地移动网络VPLMN标识；当该携带该移动通信终端的用户非首次来到拜访地时，移动通信终端的网络记录文件中有该拜访地的记录，即存在该拜访地公共陆地移动网络VPLMN标识，可直接通过移动通信终端读取网络记录文件中的拜访地公共陆地移动网络VPLMN标识。
步骤S102，将所述移动通信终端的网络记录文件内的所述当前拜访地公共陆地移动网络标识和归属地公共陆地移动网络标识同时添加入等效公共陆地移动网络列表。
具体实现中，等效公共陆地移动网EPLMN列表主要用于存储多个等效公共陆地移动网EPLMN标识信息，步骤S101中将获取到的拜访地公共陆地移 动网信息VPLMN标识存储于移动通信终端的网络记录文件内，移动通信终端记录文件中还保存有归属地公共陆地移动网络HPLMN标识，本实施例中，归属地公共陆地移动网络HPLMN标识还包括等效归属地公共陆地移动网络EHPLMN标识，将移动通信终端记录文件中的当前拜访地公共陆地移动网络标识和归属地公共陆地移动网络标识同时添加入等效公共陆地移动网络列表中，为网络搜索提供搜索资源。将当前拜访地公共陆地移动网络VPLMN标识和归属地公共陆地移动网络HPLMN标识添加入等效公共陆地移动网络列表，该当拜访地公共陆地移动网络VPLMN和等效归属地公共陆地移动网络EHPLMN为等效关系，即在找网过程中处于同一优先级。
步骤S103，根据所述等效公共陆地移动网络列表进行网络搜索。
具体实现中，根据添加后的所述移动通信终端的等效公共陆地移动网EPLMN列表，将该列表中的多个等效公共陆地移动网EPLMN信息进行同步网络搜索。
步骤S104，当搜索到所述等效公共陆地移动网络列表中的任意一个网络时，执行所述移动通信终端的网络注册操作。
具体实现中，当搜索到与所述等效公共陆地移动网络EPLMN列表中的任意一个网络时，执行所述移动通信终端的网络注册操作，任意一个网络包括列表中的移动通信终端的拜访地公共陆地移动网络VPLMN和归属地公共陆地移动网络HPLMN中的任何一个等效的公共陆地移动网络EPLMN，如归属地为中国，搜索到中国联通的46001时，则可根据该网号进行网络注册操作。
在本发明实施例中，通过当移动通信终端的网络记录文件中不存在当前拜访地公共陆地移动网络标识时，获取当前拜访地公共陆地移动网络标识并存储至移动通信终端的网络记录文件内，将移动通信终端的网络记录文件内的当前拜访地公共陆地移动网络标识和归属地公共陆地移动网络标识同时添加入等效公共陆地移动网络列表，根据等效公共陆地移动网络列表进行网络搜索，当搜索到等效公共陆地移动网络列表中的任意一个网络时，执行移动通信终端的网络注册操作。通过获取移动通信终端当前拜访地公共陆地移动网络标识并存储至网络记录文件内，并按照网络记录文件内的当前拜访地公共陆地移动网络标识和归属地公共陆地移动网络标识同时添加入等效公共陆地移动网络列表 的方式进行同时找网，这样移动通信终端在当前拜访地接入网络的成功率和速率都可能极大提高，就有利于极大的缩短用户通信等待时长(理想状态下移动通信终端可能只需要几秒就可以完成网络接入)，进而有利于极大的提高用户通信体验。
请参阅图2，为本发明实施例提供的另一种网络接入方法的流程示意图，该方法包括以下步骤。
步骤S201，判断移动通信终端的网络记录文件中是否存在当前拜访地公共陆地移动网络标识。
具体实现中，步骤S201可具体包括步骤A和步骤B：
步骤A：判断归属地公共陆地移动网络信号强度是否小于网络预设阈值；
具体实现中，当移动通信终端漫游至其他国家重新开机时，移动通信终端并不知道自己处于漫游状态，会继续搜索已登记的公共陆地移动网RPLMN，而由于漫游地区并不存在已登记的公共陆地移动网RPLMN，因而会找网失败，并浪费了大量的找网时间。本实施例中，当移动通信终端搜索到的信号较弱时，判断该移动通信终端的归属地公共陆地移动网络HPLMN信号强度是否小于网络预设阈值，以判断携带该移动通信终端的用户是否处于归属地或拜访地或归属地到拜访地之间的地理范围，其中，网络预设阈值为判断当前的信号强度，从而判断是否需要进行网络切换，由移动通信终端系统提供。当携带移动通信终端的用户从归属地前往拜访地的过程中，当移动通信终端处于归属地公共陆地移动网络HPLMN的有效范围内时，移动通信终端会搜索到该归属地公共陆地移动网络HPLMN，而当搜索该归属地公共陆地移动网络HPLMN越来越弱，直至达到小于网络预设阈值，再进行网络搜索操作。
步骤B：当所述归属地公共陆地移动网络信号强度小于网络预设阈值时，判断移动通信终端的网络记录文件中是否存在当前拜访地公共陆地移动网络标识。
具体实现中，当归属地公共陆地移动网络HPLMN信号强度小于网络预设阈值时，判断移动通信终端的网络记录文件是否存在当前拜访地公共陆地移动网络VPLMN标识，移动通信终端的网络记录文件是指移动通信终端中用于记 录网络信息的文件，如EFS文件。当携带该移动通信终端的用户首次来到某拜访地时，移动通信终端的网络记录文件中没有该拜访地的记录，即不存在该拜访地公共陆地移动网络VPLMN标识，则需要通过将该拜访地公共陆地移动网络VPLMN添加至移动通信终端的网络记录文件中，以备该携带该移动通信终端的用户第二次或后期多次来到该拜访地时，可根据读取该网络记录文件，获取拜访地公共陆地移动网络VPLMN标识；当该携带该移动通信终端的用户非首次来到拜访地时，移动通信终端的网络记录文件中有该拜访地的记录，即存在该拜访地公共陆地移动网络VPLMN标识，可直接通过移动通信终端读取网络记录文件中的拜访地公共陆地移动网络VPLMN标识。当所述移动通信终端的网络记录文件存在拜访地公共陆地移动网络标识VPLMN时，表示该携带该移动通信终端的用户为第二次或后期多次来到该拜访地，在首次进入该拜访地已经将拜访地公共陆地移动网络VPLMN标识存储至该移动通信终端的网络记录文件中，并将拜访地公共陆地移动网络VPLMN标识和归属地公共陆地移动网络HPLMN标识添加入等效公共陆地移动网络列表。当移动通信终端的网络记录文件中不存在当前拜访地公共陆地移动网络VPLMN标识时，执行步骤S203。
步骤S202，当移动通信终端的网络记录文件中不存在当前拜访地公共陆地移动网络标识时，获取所述当前拜访地公共陆地移动网络标识并存储至所述移动通信终端的网络记录文件内。
具体实现中，当移动通信终端的网络记录文件不存在拜访地公共陆地移动网络VPLMN标识时，表示该携带该移动通信终端的用户为首次来到该拜访地或首次将拜访地公共陆地移动网络VPLMN标识记录到移动通信终端的网络记录文件中，通过手动或者其它共享方式等获取该拜访地公共陆地移动网络VPLMN标识，并存储至该移动通信终端的网络记录文件内。
步骤S203，从所述移动通信终端的网络记录文件中读取所述当前拜访地公共陆地移动网络标识和归属地公共陆地移动网络标识。
具体实现中，通过访问移动通信终端的网络记录文件，读取出当前拜访地公共陆地移动网络VPLMN标识和归属地公共陆地移动网络HPLMN标识，其中归属地公共陆地移动网络HPLMN标识已经在首次进行找网的时候，存储到 移动通信终端的网络记录文件中，该归属地公共陆地移动网络HPLMN标识包括与移动通信终端USIM卡相匹配的HPLMN和等效归属地公共陆地移动网络EHPLMN标识。
步骤S204，将所述移动通信终端的网络记录文件内的所述当前拜访地公共陆地移动网络标识和归属地公共陆地移动网络标识同时添加入等效公共陆地移动网络列表。
具体实现中，等效公共陆地移动网EPLMN列表主要用于存储多个等效公共陆地移动网EPLMN标识信息，步骤S203中将获取到的拜访地公共陆地移动网信息VPLMN标识存储于移动通信终端的网络记录文件内，移动通信终端记录文件中还保存有归属地公共陆地移动网络HPLMN标识，本实施例中，归属地公共陆地移动网络HPLMN标识还包括等效归属地公共陆地移动网络EHPLMN标识，将移动通信终端记录文件中的当前拜访地公共陆地移动网络标识和归属地公共陆地移动网络标识同时添加入等效公共陆地移动网络列表中，为网络搜索提供搜索资源。将当前拜访地公共陆地移动网络VPLMN标识和归属地公共陆地移动网络HPLMN标识添加入等效公共陆地移动网络列表，该当拜访地公共陆地移动网络VPLMN和等效归属地公共陆地移动网络EHPLMN为等效关系，即在找网过程中处于同一优先级。
步骤S205，根据所述等效公共陆地移动网络列表，发送广播找网指令，执行网络搜索操作。

网络搜索单元13，用于根据所述等效公共陆地移动网络列表进行网络搜索。
具体实现中，根据添加后的所述移动通信终端的等效公共陆地移动网EPLMN列表，将该列表中的多个移动通信终端等效公共陆地移动网EPLMN信息进行同步网络搜索。

获取单元11，用于当移动通信终端的网络记录文件不存在拜访地公共陆地移动网络标识时，获取所述拜访地公共陆地移动网络并存储至所述移动通信终端的网络记录文件内。
具体实现中，当移动通信终端的网络记录文件不存在拜访地公共陆地移动网络VPLMN时，表示该携带该移动通信终端的用户为首次来到该拜访地或首 次将拜访地公共陆地移动网络VPLMN记录到移动通信终端的网络记录文件中，通过手动或者其它如共享等方式获取该拜访地公共陆地移动网络VPLMN，并存储至该移动通信终端的网络记录文件内。

列表添加单元27，用于将所述拜访地公共陆地移动网络和等效归属地公共陆地移动网络添加入等效公共陆地移动网络列表。
具体实现中，等效公共陆地移动网EPLMN列表主要用于存储多个等效公共陆地移动网EPLMN信息，步骤S101中获取到的移动通信终端的等效归属地公共陆地移动网信息EPLMN将被存储于该等效公共陆地移动网EPLMN列表中，为网络搜索提供搜索资源。将所述拜访地公共陆地移动网络和等效归属地公共陆地移动网络添加入等效公共陆地移动网络列表，该拜访地公共陆地移动网络和归属地公共陆地移动网络为等效关系，即在找网过程中处于同一优先级。
网络搜索单元28，用于根据所述等效公共陆地移动网络列表，发送广播找网指令，执行网络搜索操作。
具体实现中，等效公共陆地移动网EPLMN列表主要用于存储多个等效公共陆地移动网EPLMN信息，根据添加后的所述等效公共陆地移动网EPLMN列表，根据该列表中的移动通信终端的拜访地公共陆地移动网络VPLMN标识和等效归属地公共陆地移动网络EHPLMN标识进行同步网络搜索，列表中的所有拜访地公共陆地移动网络VPLMN和等效归属地公共陆地移动网络EHPLMN均处于同一优先级。在进行搜索时，移动通信终端需要根据所述等效公共陆地移动网络EPLMN列表，生成包含等效公共陆地移动网络EPLMN列表中的等效公共陆地移动网络EPLMN信息的找网指令，接收与所述等效公共陆地移动网络列表相应的广播消息，执行网络搜索操作。
