本发明要求2015年4月30日递交的发明名称为“一种网络接入方法和移动通信终端”的申请号201510221597.7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
本发明涉及移动通信技术领域，尤其涉及一种网络接入方法和移动通信终端。
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。该网路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。
公共陆地移动网络的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，用户可通过各个运营商提供的移动网络可以进行方便快捷的通信。随着人们生活水平的提高，携带通信终端设备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，其移动通信终端(如手机)等需要重新找网，以获取公共陆地移动网络的网络标识。
当移动通信终端从归属地移动到拜访地(例如移动通信终端从归属国漫游至拜访国)，移动通信终端需要接入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移动通信终端从某归属地移动到拜访地，移动通信终端经常需要很长的时间(有时候甚至可能需要等待几十分钟以上)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。
发明内容
本发明实施例所要解决的技术问题在于，提供一种网络接入方法和移动通信终端，移动通信终端在关机或者开启飞行模式之前，当判断出等效公共陆地 移动网络EPLMNEPLMN列表中不存在拜访地公共陆地移动网络VPLMN时，从运营商服务器中获取运营商推送至所述运营商服务器的共享网络信息中的VPLMN，并将VPLMN添加至EPLMNEPLMN列表。当以已登记公共陆地移动网络RPLMN在拜访地进行搜网时，因搜索的RPLMN与VPLMN等效，而使得移动终端可以驻留到该小区，并尝试发起搜网注册过程，加快搜网速度。
为了解决上述技术问题，本发明实施例第一方面公开了一种网络接入方法，包括：
移动通信终端判断等效公共陆地移动网络EPLMN列表中是否存在拜访地PLMN的网络标识，其中，所述EPLMN列表包括归属地PLMN的网络标识和拜访地PLMN的网络标识，所述拜访地PLMN的网络标识为与所述移动通信终端附带的客户识别SIM卡所属的归属地运营商签订了漫游协议的拜访地运营商的PLMN的网络标识；
当判断结果为否时，获取运营商商服务器中存储的共享网络信息并从所述共享网络信息查找所述拜访地PLMN的网络标识，其中，所述运营商服务器为归属地运营商的服务器或与所述归属地运营商签订漫游协议的拜访地运营商的服务器；
添加所述拜访地PLMN的网络标识至EPLMN列表；以及
根据所述EPLMN列表进行网络接入。
本发明实施例第二方面公开了一种移动通信终端，包括：
存储器，存储计算机可读程序代码；以及
处理器，用于执行所述计算机可读程序代码，以执行以下操作：
判断等效公共陆地移动网络EPLMN列表中是否存在拜访地PLMN的网络标识，其中，所述EPLMN列表包括归属地PLMN的网络标识和拜访地PLMN的网络标识，所述拜访地PLMN的网络标识为与所述移动通信终端附带的客户识别模块所属的归属地运营商签订了漫游协议的拜访地运营商的PLMN的网络标识；
当所述判断结果为否时，获取运营商商服务器中存储的共享网络信息并从所述共享网络信息查找所述拜访地PLMN的网络标识，其中，所述运营商服务器为归属地运营商的服务器或与所述归属地运营商签订漫游协议的拜访地 运营商的服务器；
添加所述获取到的所述拜访地PLMN的网络标识至EPLMN列表；以及
根据所述EPLMN列表进行网络接入。
本发明实施例第三方面公开一种计算机可读存储媒介，存储计算机可读程序代码，所述计算机可读程序代码运行于移动通信终端中，以用于：
判断等效公共陆地移动网络EPLMN列表中是否存在拜访地PLMN的网络标识，其中，所述EPLMN列表包括归属地PLMN的网络标识和拜访地PLMN的网络标识，所述拜访地PLMN的网络标识为与所述移动通信终端附带的客户识别模块所属的归属地运营商签订了漫游协议的拜访地运营商的PLMN的网络标识；
当所述判断结果为否时，获取运营商商服务器中存储的共享网络信息并从所述共享网络信息查找所述拜访地PLMN的网络标识，其中，所述运营商服务器为归属地运营商的服务器或与所述归属地运营商签订漫游协议的拜访地运营商的服务器；
添加所述获取到的所述拜访地PLMN的网络标识至EPLMN列表；以及
根据所述EPLMN列表进行网络接入。
本发明实施例的技术方案中，不仅将移动通信终端归属的PLMN的网络标识添加到等效公共陆地移动网络EPLMN列表，并且还将获取到的与移动通信终端归属的PLMN的运营商签订了漫游协议的拜访地运营商的PLMN的网络标识也添加到EPLMN列表，其中，EPLMN列表中存储了网络标识的各PLMN之间被移动通信终端在一定程度上视为等效，因此，如果根据所述EPLMN列表进行所述移动通信终端的网络接入，那么由于EPLMN列表中存储了与移动通信终端归属的PLMN的运营商签订了漫游协议的一些拜访地运营商的PLMN的网络标识，因此，当所述移动通信终端从归属地移动到某拜访地，所述移动通信终端在移动到的当前拜访地进行网络搜索，那么网络搜索命中EPLMN列表中存储了网络标识的某个PLMN的可能性将极大提高，因此，所述移动通信终端在当前拜访地接入网络的效率可能极大提高，这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。

具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明的是，在本发明实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本发明。在本发明实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
PLMN(Public Land Mobile Network，公共陆地移动网络)，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(PSTN)互连，形成整个地区或国家规模的通信网。PLMN＝MCC+MNC，例如中国移动的PLMN为46000、46002、46007、46008，中国联通的PLMN为46001、46006、46009。PLMN是一个无线通讯系统，趋向于面向陆地上的例如交通工具或步行中的移动用户。然而，移动和 便携的因特网用户也越来越普及。一个理想的公共陆地移动网络PLMN系统提供给移动和便携用户和固定网络相当的服务，这在地形比较复杂的区域是一个特殊的挑战，因为基站会难以被找到和维持。在都市的环境中有很多的障碍，像是建筑物，和各种射频都能引起杂音和干扰的辐射。
RPLMN(RegisteredPLMN已登记PLMN)：已登记PLMN。是移动通信终端在上次关机或脱网前登记上的PLMN。在3GPP 2003年第TSG TP-21次会议上决定，将该参数从USIM卡上删掉，而将其保存在终端的内存中。
EPLMN(EquivalentPLMN等效PLMN)：为与移动通信终端当前所选择的PLMN处于同等地位的PLMN，其优先级相同。
EHPLMN(EquivalentHome PLMN等效归属PLMN)：为与移动通信终端当前所选择的PLMN处于同等地位的本地PLMN。其实：EHPLMN和EPLMN就好比是中移动的新建的158网络，而PLMN就好比是原来的135～139网络。
HPLMN(Home PLMN归属PLMN)：为移动通信终端用户归属的PLMN。也就是说，移动通信终端USIM卡上的IMSI号中包含的MCC和MNC与HPLMN上的MCC和MNC是一致的，对于某一用户来说，其归属的PLMN只有一个。
VPLMN(Visited PLMN拜访地PLMN)：为移动通信终端用户访问拜访地的PLMN。其PLMN和存在SIM卡中的IMSI的MCC，MNC是不完全相同的。当移动通信终端丢失覆盖后，一个VPLMN将被选择。
移动通信终端包含但不限于手机、手表、平板电脑等具有通信功能的终端。
参见图1，是本发明实施例提供的网络接入方法一种实施方式的流程示意图，该方法包括：
步骤S102：移动通信终端判断等效公共陆地移动网络EPLMN列表中是否存在拜访地PLMN的网络标识，其中，所述EPLMN列表包括归属地PLMN的网络标识和拜访地PLMN的网络标识，所述拜访地PLMN的网络标识为与所述移动通信终端附带的客户识别模块(SIM卡)所属的归属地运营商签订了漫游协议的拜访地运营商的PLMN的网络标识。
具体地，移动通信终端可以是手机，当用户携带移动通信终端进行出国旅行、出差等时，移动通信终端网络将处于国际漫游阶段，其中拜访地与归属地 属于不同的国家，归属地可以为中国，拜访地可以为美国、韩国等。例如，用户携带有手机从中国到达美国时，归属地为中国，拜访地为美国，手机网络将处于国际漫游阶段。
移动通信终端在到达拜访地之前，可以预先判断EPLMN列表中是否存在拜访地PLMN的网络标识，其中，拜访地PLMN的网络标识为与移动通信终端附带的SIM卡所属的归属地运营商签订漫游协议的拜访地运营商网络的网络标识。例如，用户携带手机去美国出差，手机在到达美国之前，手机可以预先判断存储的EPLMN列表中是否存在美国的网络标识。
本发明实施例中，网络标识可以包括网络号段，如中国移动包含四个号段，分别为46000、46002、46007以及46008；中国联通包含三个号段，分别为46001、46006以及46009。EPLMN列表中可以包含有预先添加的HPLMN归属地PLMN的网络标识和VPLMN拜访地公共陆地移动网络的网络标识；或者，EPLMN列表中可以包含有预先添加的EHPLMN等效归属地PLMN的网络标识和VPLMN拜访地公共陆地移动网络的网络标识；或者EPLMN列表中可以包含有预先添加的HPLMN归属地PLMN的网络标识、EHPLMN等效归属地PLMN的网络标识和VPLMN拜访地公共陆地移动网络的网络标识。预先添加的VPLMN拜访地公共陆地移动网络的网络标识与终端在上次关机或脱网前登记上的RPLMN等效，其优先级相同。
当判断结果为是时，即移动通信终端的EPLMN列表中存在拜访地PLMN的网络标识，可以触发执行步骤S108根据EPLMN列表进行网络接入；当判断结果为否时，即移动通信终端的EPLMN列表中不存在拜访地PLMN的网络标识，可以触发执行步骤S104获取运营商服务器中存储的共享网络信息并从共享网络信息查找拜访地PLMN的网络标识。
步骤S104：当判断结果为否时，获取运营商服务器中存储的共享网络信息并从所述共享网络信息查找所述拜访地PLMN的网络标识，其中，所述运营商服务器为归属地运营商的服务器或与所述归属地运营商签订漫游协议的拜访地运营商的服务器。
具体地，当步骤S102的判断结果为否时，可以获取运营商服务器中存储的共享网络信息并从共享网络信息查找拜访地PLMN的网络标识，移动通信 终端可以向运营商服务器发送获取运营商服务器存储的共享网络信息的请求。移动通信终端可以接收运营商服务器响应请求而发送的共享网络信息。其中，运营商服务器可以存储有共享网络信息，共享网络信息包含但不限于包括归属地PLMN的网络标识、等效归属地PLMN的网络标识和拜访地PLMN的网络标识，即共享网络信息可以包含有HPLMN、EPLMN和VPLMN等。共享网络信息可以是其他终端推送至运营商服务器的拜访地PLMN的网络标识，以使移动通信终端通过查找运营商服务器中的共享网络信息获取拜访地PLMN的网络标识。
例如，手机可以获取运营商服务器中存储的共享网络信息并从共享网络信息查找拜访地PLMN的网络标识。
步骤S106：添加拜访地PLMN的网络标识至EPLMN列表。
具体地，可以将步骤S104接收的拜访地公共陆地移动网络PLMN的网络标识添加至EPLMN列表。EPLMN列表的展示示意图可以如图2所示，其中，EPLMN(EquivalentPublic LandMobile Network，等效PLMN)网络，是与用户终端当前所选择的PLMN(Public Land Mobile Network，公共陆地移动网络)处于同等地位的公共陆地移动网络，其优先级相同。EPLMN主要解决共享网络与原网络的用户驻留和漫游策略。运营商可以配置等效的PLMN网络，这些网络之间可以实现通信网络资源共享。从业务的角度，它使得不同运营商的网络资源之间，或者同一运营商定义的不同PLMN之间可以实现通信网络资源共享。EPLMN列表中可以包含有预先添加的HPLMN归属地PLMN的网络标识和VPLMN拜访地公共陆地移动网络的网络标识；或者，EPLMN列表中可以包含有预先添加的EHPLMN等效归属地公共陆地移动网络的网络标识和VPLMN拜访地公共陆地移动网络的网络标识；或者EPLMN列表中可以包含有预先添加的HPLMN归属地公共陆地移动网络的网络标识、EHPLMN等效归属地公共陆地移动网络的网络标识和VPLMN拜访地公共陆地移动网络的网络标识。预先添加的VPLMN拜访地公共陆地移动网络的网络标识与终端在上次关机或脱网前已登记的RPLMN等效，其优先级相同。
步骤S108：根据所述EPLMN列表中的网络标识进行网络接入。
具体地，移动通信终端从归属地移动到达拜访地之后，可以接收用户输入 的开机指令或者关闭当前飞行模式的指令，移动通信终端开机后或者关闭当前飞行模式之后，开始进行网络搜索。移动通信终端可以根据EPLMN列表中的网络标识进行网络搜索。移动通信终端扫描可以获取基站广播的VPLMN拜访地公共陆地移动网络的网络标识；移动通信终端可以将上述扫描获取到的公共陆地移动网络PLMN的网络标识与上述EPLMN列表中的公共陆地移动网络PLMN的网络标识进行匹配。
当移动通信终端搜索到小区基站发送的VPLMN拜访地公共陆地移动网络的网络标识与手机EPLMNEPLMN列表中的任意一个网络标识相匹配时，移动通信终端可以发起网络注册，并建立与拜访地网络之间的通信连接。
参见图3，是本发明实施例提供的网络接入方法另一种实施方式的流程示意图，该方法包括：

移动通信终端在到达拜访地之前，可以预先判断EPLMN列表中是否存在拜访地PLMN的网络标识，其中，拜访地PLMN的网络标识为与移动通信终端附带的SIM卡所属的归属地运营商签订漫游协议的拜访地运营商网络的网络标识。例如，用户携带手机去美国出差，手机在到达美国之前，手机可以预先判断存储的EPLMN列表中是否存在美国的网络标识。
本发明实施例中，网络标识可以包括网络号段，如中国移动包含四个号段，分别为46000、46002、46007以及46008；中国联通包含三个号段，分别为46001、 46006以及46009。EPLMN列表中可以包含有预先添加的HPLMN归属地PLMN的网络标识和VPLMN拜访地公共陆地移动网络的网络标识；或者，EPLMN列表中可以包含有预先添加的EHPLMN等效归属地PLMN的网络标识和VPLMN拜访地公共陆地移动网络的网络标识；或者EPLMN列表中可以包含有预先添加的HPLMN归属地PLMN的网络标识、EHPLMN等效归属地PLMN的网络标识和VPLMN拜访地公共陆地移动网络的网络标识。预先添加的VPLMN拜访地公共陆地移动网络的网络标识与终端在上次关机或脱网前登记上的RPLMN等效，其优先级相同。
当判断结果为是时，即移动通信终端的EPLMN列表中存在拜访地PLMN的网络标识，可以触发执行步骤S308根据EPLMN列表进行网络接入；当判断结果为否时，即移动通信终端的EPLMN列表中不存在拜访地PLMN的网络标识，可以触发执行步骤S304获取运营商服务器中存储的共享网络信息并从共享网络信息查找拜访地PLMN的网络标识。
步骤S304：当判断结果为否时，获取运营商服务器中存储的共享网络信息并从所述共享网络信息查找所述拜访地PLMN的网络标识，其中，所述运营商服务器为归属地运营商的服务器或与所述归属地运营商签订漫游协议的拜访地运营商的服务器。
具体地，当步骤S302的判断结果为否时，可以获取运营商服务器中存储的共享网络信息并从共享网络信息查找拜访地PLMN的网络标识，移动通信终端可以向运营商服务器发送获取运营商服务器存储的共享网络信息的请求。移动通信终端可以接收运营商服务器响应请求而发送的共享网络信息。其中，运营商服务器可以存储有共享网络信息，共享网络信息包含但不限于包括归属地PLMN的网络标识、等效归属地PLMN的网络标识和拜访地PLMN的网络标识，即共享网络信息可以包含有HPLMN、EPLMN和VPLMN等。共享网络信息可以是其他终端推送至运营商服务器的拜访地PLMN的网络标识，以使移动通信终端通过查找运营商服务器中的共享网络信息获取拜访地PLMN的网络标识。

具体地，移动通信终端可以是手机，当用户携带移动通信终端进行出国旅行、出差等时，移动通信终端网络将处于国际漫游阶段，当到达拜访地之后，移动通信终端可以在所述拜访地搜索网络。
例如，当用户携带手机从归属地中国到达拜访地美国时进行第一次开机，手机可以在美国进行网络搜索。
步骤S310：若在所述拜访地搜索到了与所述EPLMN列表中的网络标识相匹配的拜访地PLMN，建立所述移动通信终端与所述相匹配的拜访地PLMN之间的通信连接。
