Description

APN匹配方法、终端及存储介质
本申请要求于2019年10月31日提交中国专利局、申请号为“201911055000.0”、申请名称为“APN匹配方法、终端及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种APN匹配方法、终端及存储介质。
背景技术
APN(Access Point Name，接入点名称)是移动网络数据业务的基本配置参数之一，不同APN标识了终端访问网络使用数据业务的方式。
现有的通过APN建立网络连接的方法，通常先对APN进行获取，获取后使用与运营商对应的APN进行上网。现有的APN匹配方法，通常在终端中预置国内或者全球范围内的所有运营商的公共陆地移动网络(Public Land Mobile Network，缩写：PLMN)和APN之间的对应关系。每个运营商通常会有多个PLMN，因此会出现多个PLMN对应同一组APN的情况。在用户将全球用户识别卡(Universal Subscriber Identity Module，缩写：USIM)放入终端后，终端可以从指定文件中读取国际移动用户识别码(International Mobile Subscriber Identification Number，缩写：IMSI)，通过IMSI前几位读取运营商PLMN，即归属PLMN，再根据终端中预置的列表查找到对应的APN，并选择APN，保证用户使用连接网络并使用数据业务。
但是，随着用户数量的增加，如果原有PLMN不足以容纳，运营商很可能增加新的PLMN，由于终端中预置的列表不会随之更新，就会出现在预置APN列表中难以匹配到对应PLMN的情况，那么终端将难以使用APN建立网络连接。
申请内容
本申请实施例提供一种APN匹配方法、终端及存储介质，用于解决现有技术中当运营商增加新的PLMN时，终端中用于存储运营商PLMN与运营商PLMN对应的APN信息之间关系的列表中没有存储新增的PLMN时，难以匹配到APN的问题。

具体实施方式
为了更好的理解本申请的技术方案，下面结合附图对本申请实施例进行详细描述。
应当明确，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。基于本申请中的实施例，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它实施例，都属于本申请保护的范围。
在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请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它含义。
应当理解，本文中使用的术语“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
针对预置APN列表中找不到对应PLMN的情况，现有技术中提供了以下方案：
方案一：使用EHPLMN(Equivalent Home Public Land Mobile Network，等效的归属PLMN)进行APN匹配。
具体地，EHPLMN为与终端当前所选择的PLMN处于同等地位(等效)的本地PLMN，EHPLMN存储于全球用户识别(Universal Subscriber Identity Module，缩写：USIM)卡中，举例来说，中国移动对应的HPLMN是46000，EHPLMN可以有：46002，46007等。
如附图1所示，进行网络注册(Attach)后，当用户需要上网时，需要先进行PDP(Packet Data Protocol)上下文激活，如果使用HPLMN匹配不到对应的APN时，则读取USIM卡中的EHPLMN，使用EHPLMN进行APN的匹配。
针对方案一，如果HPLMN没有匹配到对应的APN，则USIM卡中需要有EHPLMN，而且EHPLMN的匹配必须要准确，否则APN的匹配就会出错，而全球的运营商非常多，难以避免一定数量的运营商的卡没有写入EHPLMN或者一定数量的卡EHPLMN不准确。
方案二：使用4G(4rd Generation，第4代移动通信技术)网络注册(Attach)时网络分配的APN；
具体地，如附图2所示，4G在注册(Attach)时，如果终端未上报APN，网络会分配默认APN承载于注册接受请求中，若终端使用HPLMN匹配APN失败，终端可使用4G网络分配的默认承载的APN进行PDP上下文激活。针对方案二：使用4G网络在Attach时网络分配的APN有以下几个缺点：
(1)Attach时网络分配的APN可能是IMS的APN，终端无法通过该APN连接网络；
(2)Attach时网络分配的APN中可能不会携带DNS(domain name system，域名系统)信息，终端无法通过该APN连接网络；
(3)无法解决5G(5th generation mobile networks，第5代移动通信技术)、3G(3rd Generation，第3代移动通信技术)及2G(2rd Generation，第2代移动通信技术)等情况下，APN为空的问题。
综上所示，本申请实施例提供了一种APN匹配方法，该方法的核心思想为：当HPLMN所匹配到的APN为空(即没有匹配到对应的APN)时，使用在此之前已经注册成功的PLMN进行APN的匹配。通过上述方法，极大的增加当运营商增加新的PLMN时，终端中用于存储运营商PLMN与运营商PLMN对应的APN信息之间关系的列表中没有存储新增的PLMN或者当终端出现异常时APN匹配成功的概率，且能同时适应5G、4G、3G及2G等，可靠性强。
下面结合附图本申请实施例提供的一种APN匹配方法进行进一步说明。
请参见附图3，附图3示出了本申请实施例提供的一种APN匹配方法的流程图。
一种APN匹配方法，应用于终端，包括：
步骤S01：终端获取归属公共陆地移动网络HPLMN；
步骤S02：终端进行PLMN网络注册，注册成功后，使用HPLMN在第一列表中进行APN匹配，第一列表存储有至少一个PLMN与APN的对应关系；
步骤S03：如果在第一列表中没有匹配到与HPLMN对应的APN，终端使用第二列表中的PLMN在第一列表中进行APN匹配，第二列表中的PLMN为已注册的PLMN。
可以理解，本申请实施例提供了一种APN匹配方法，当HPLMN所匹配到的APN为空(即没有匹配到对应的APN)时，使用第二列表中过去已成功注册过的PLMN进行APN匹配。通过上述方法，极大的增加当运营商增加新的PLMN时，终端中用于存储运营商PLMN与运营商PLMN对应的APN信息之间关系的列表中没有存储新增的PLMN或者当终端出现异常时，APN匹配的成功率，且能同时适应5G、4G、3G及2G等，可靠性强。
下面对本申请实施例提供的APN匹配方法进行更为具体的介绍。
针对步骤S01：获取归属公共陆地移动网络HPLMN；
具体地，终端可以是无线终端，无线终端可以是只向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经RAN(Radio Access Network，无线接入网)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，PCS(Personal Communication Service，个人通信业务)电话、无绳电话、会话发起协议(SIP)话机、WLL(Wireless Local Loop，无线本地环路)站、PDA(Personal Digital Assistant，个人数字助理)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)或用户设备。
归属公共陆地移动网络HPLMN为终端用户归属的公共陆地移动网络PLMN，也就是说，终端USIM卡上的IMSI中包含的移动国家码MCC和移动网络码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。
获取归属公共陆地移动网络HPLMN的过程包括：
当终端插入USIM卡时，终端的AP(application processor，应用处理器)向调制解调器(Modem)发起HPLMN获取请求，调制解调器与USIM卡之间进行通信交互，调制解调器从USIM卡的IMSI文件中读取IMSI，并从IMSI中解析得到归属公共陆地移动网络HPLMN，将归属公共陆地移动网络HPLMN返回给AP(application processor，应用处理器)，其中，HPLMN为IMSI的前五位。
终端中预先设置有用于存储运营商PLMN与的运营商PLMN对应的APN信息之间关系的列表，即第一列表。第一列表在终端出厂时预置在终端中，第一列表包括多个运营商PLMN与多个运营商PLMN对应的APN之间的关系。当出现新的运营商PLMN时，由于终端在出厂之前已经设置好第一列表，因此，新的运营商PLMN可能无法匹配到对应的APN。
针对步骤S02：终端进行PLMN网络注册，注册成功后，使用HPLMN在第一列表中进行APN匹配，第一列表存储有至少一个PLMN与APN的对应关系；
具体地，终端开机时或者脱网后需要重新联网时，需要重新进行PLMN网络注册，PLMN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。该网路必须与PSTN(Public Switched Telephone Network，公众交换电话网)互连，形成整个地区或国家规模的通信网。其中，PLMN包括MCC(Mobile Country Code，移动国家码)和MNC(Mobile Network Code，移动网络号)。例如China Mobile(中国移动)的PLMN：46000，其中，MCC为460，MNC为00。
终端网络注册的过程大致为：终端选择至少一个PLMN，再通过接入网设备和与选择的PLMN对应的核心网设备，在选择的至少一个PLMN中使用一个进行网络注册。
终端网络注册具体过程包括：
步骤S021：终端接收接入网设备发送的系统信息，系统信息中包括PLMN标识，在本申请一个或者多个实施例中，PLMN标识的数量为多个。
步骤S022：终端向接入网设备发送注册请求，注册请求包括终端向至少一个PLMN(通常包括一个或者两个PLMN，下面以包括一个PLMN进行举例说明)请求注册的信息以及终端的IMSI标识；
步骤S023：接入网设备根据注册请求，获取注册请求中包括的一个PLMN对应的请求注册的信息，并转发该注册请求给对应的核心网设备，需要知道的是，每个PLMN的标识对应一个PLMN，每个PLMN对应一个核心网设备，且每个PLMN的标识还对应一个注册请求消息，一个核心网设备只能与该核心网设备对应的PLMN进行通信。
步骤S024：核心网设备得到PLMN标识以及终端IMSI标识后，向HLR(HomeLocation Register，归属位置寄存器)中请求进行认证，并根据HLR下达的用户签约数据对终端进行鉴权，同时核心网设备将终端的当前位置信息上传HLR。鉴权通过后，核心网设备就会向接入网设备发送注册接受消息，接入网设备将注册接受信息返回给终端，进而PLMN网络注册成功。
更具体的，运营商的主干网络分为三层：核心层、汇聚层、接入层，从接入层到终端的网络，就是接入网。接入网可以为GPRS(General Packet Radio Service，通用分组无线服务技术)、GSM(Global System For Mobile Communication，全球移动通信)、3G等。核心层为实现主干网络之间的优化传输功能，核心网是核心层上提供终端连接、对终端的管理以及对业务完成承载的网络，即PLMN，其中，核心网为承载网络提供到外部网络的接口。
其中，接入网设备可以为eNB(evolved Node B，演进型基站)、RNC(RadioNetwork Controller，无线网络控制器)或BSC(Base Station Controller，基站控制器)。核心网设备可以为MME(Mobility Management Entity，移动性管理实体)、SGSN(Serving GPRS Support Node，服务GPRS支撑节点)或MSC(Mobile Switching Center，移动交换中心)。
更具体的，以移动通信系统的PS(Packet Switch，分组交换)域为例，在3G中，接入网设备为RNC，核心网设备为SGSN；在4G(4th Generation，第四代移动通信技术)中，接入网设备为eNB，核心网设备为MME；在2G(2rd Generation，第二代移动通信技术)中，接入网设备为BSC、核心网设备为SGSN。以移动通信系统的CS(Circuit Switch，电路交换)域为例，在3G/2G中，接入网设备为RNC(3G)/BSC(2G)，核心网设备为MSC。
PLMN注册成功后，使用HPLMN在第一列表中进行APN匹配具体为使用HPLMN在第一列表进行标识匹配，如果匹配上与HPLMN标识相同的字段，则获取与HPLMN标识相同的字段对应的APN，以完成APN的匹配。
第一列表可以存储于终端的数据库中，也可以存储于配置文件中。
进一步地，在终端进行PLMN网络注册，并注册成功后，APN匹配方法还包括：
判断终端当前是否为漫游状态。
如果不是漫游状态，进一步判断第二列表中是否已经存储有当前注册的PLMN，如果第二列表中未存储有当前注册的PLMN，则将当前注册的PLMN存储于第二列表中；如果第二列表中已经存储有当前注册的PLMN，则不进行将所当前注册的PLMN存储 在第二列表的操作；如果是漫游状态，则不进行将所当前注册的PLMN存储在第二列表的操作。其中，当前注册的PLMN由终端从接入网设备返回的注册接受信息中解析得到。
需要说明的是，在本申请一个或者多个实施例中，第二列表用于存储当前注册成功的和/或历史注册成功的且与HPLMN属于同一运营商(即非漫游的)的PLMN，因此，上述的已注册的PLMN可以是当前注册成功的且为非漫游的PLMN，也可以是历史注册成功的且为非漫游的PLMN。
进一步的，判断终端当前是否为漫游状态，具体包括：判断HPLMN与当前注册的PLMN是否属于同一运营商，如果否，则确定当然终端处于漫游状态，如果是，则确定当前终端不处于漫游状态。
举例来说，中国移动(China Mobile)有“46000，46002，46007”3个PLMN，当HPLMN是46000，注册上的网络PLMN是46002时，虽然HPLMN与注册上网络PLMN不相同，但是都是属于同一运营商中国移动(China Mobile)，因此，不处于漫游状态。
针对步骤S03：如果第一列表中没有匹配到与HPLMN对应的APN，终端使用第二列表中的PLMN在第一列表中进行APN匹配，第二列表中的PLMN为已注册的PLMN。
具体地，终端对第二列表进行遍历，当匹配到APN时，结束遍历，当未匹配到APN时，选择第二列表中的下一个PLMN进行匹配，直到匹配到APN或者第二列表中的所有PLMN均未匹配到APN为止。
终端对第二列表进行遍历可以按照第二列表内PLMN的保存的时间顺序进行遍历或者按照PLMN的数值大小的排序进行遍历等等，本申请实施例对此不做限定。优选地，可以按照第二列表内PLMN的数值从小到大进行遍历(在PLMN为数值的情况下)，通常情况下，各个运营商的PLMN建立时间越早，PLMN的数值越小，依然以中国移动(China Mobile)为例，中国移动(China Mobile)有“46000，46002，46007”3个PLMN，3个PLMN的建网顺序依次为：46000，46002，46007，因此，按照建网顺序从早到晚遍历第二列表的PLMN，PLMN建网时间越早，终端内的第一列表中保存有该PLMN对应的APN的机率越大，因此，按照建网顺序从早到晚遍历第二列表中的PLMN，可以提高APN匹配成功的速度。
可选地，在本申请的其它一些实施例中，在终端使用第二列表中的PLMN在第一列表中进行APN匹配之前或者之后，还可以使用等效归属公共陆地移动网络EHPLMN在第一列表中进行APN匹配。
可选地，在终端使用第二列表中的PLMN在第一列表中进行APN匹配之前使用等效归属公共陆地移动网络EHPLMN在第一列表中进行APN匹配的方式，具体可以为：如果在第一列表中没有匹配到与HPLMN对应的APN，则在终端使用第二列表中的PLMN在第一列表中进行APN匹配之前，先使用等效归属公共陆地移动网络EHPLMN在第一列表中进行APN匹配；如果使用EHPLMN在第一列表中没有匹配到与EHPLMN对应的APN，则再使用第二列表中的PLMN在第一列表中进行APN匹配。
可选地，在终端使用第二列表中的PLMN在第一列表中进行APN匹配之前使用等效归属公共陆地移动网络EHPLMN在第一列表中进行APN匹配的方式，具体还可以为：先使用等效归属公共陆地移动网络EHPLMN在第一列表中进行APN匹配，如果等效归 属公共陆地移动网络EHPLMN在第一列表中没有匹配到与EHPLMN对应的APN，再使用HPLMN在第一列表中进行APN匹配，如果在第一列表中没有匹配到与HPLMN对应的APN，则再使用第二列表中的PLMN在第一列表中进行APN匹配。
可选地，在终端使用第二列表中的PLMN在第一列表中进行APN匹配之前使用等效归属公共陆地移动网络EHPLMN在第一列表中进行APN匹配的方式，具体可以为：终端使用第二列表中的PLMN在第一列表中进行APN匹配，如果没有匹配到对应的APN，则再使用等效归属公共陆地移动网络EHPLMN在第一列表中进行APN匹配。
可以理解，通过在终端使用第二列表中的PLMN在第一列表中进行APN匹配之前或者之后，使用等效归属公共陆地移动网络EHPLMN在第一列表中进行APN匹配，可以进一步提高APN匹配的成功率，实现了终端预置的第一列表中不包括新增的运营商PLMN与APN对应信息时，通过查询个已注册成功过的PLMN以及已知的EHPLMN获取该运营商的APN，并且通过上述APN建立网络连接，极大可能的避免了运营商PLMN扩容后造成的终端无法使用APN建立网络连接的情况发生。
进一步地，在匹配到APN之后，终端发起向网络侧发起PDP上下文激活请求，PDP上下文激活请求中携带有匹配到的APN以及服务质量等信息，当终端接收到网络侧返回的接受激活PDP上下文请求的信息时，完成PDP上下文激活过程。
请参阅附图4，图4为本申请实施例提供的一种APN匹配方法的交互流程图。如图4所示，终端包括AP(Application Processor，应用处理器)及调制解调器(Modem)，应用处理器通过调制解调器与网络端进行交互，交互过程包括：
1、USIM卡插入成功后，应用处理器向Modem发起HPLMN获取请求；
2、调制解调器从USIM卡的IMSI文件中读取IMSI，并从IMSI中解析得到归属公共陆地移动网络HPLMN，将HPLMN返回给应用处理器，应用处理器将HPLMN保存至终端内；
3、调制解调器向网络侧(包括接入层设备及核心层设备)发起注册请求；
4、网络侧返回注册接受请求给调制解调器，注册接受请求携带注册的PLMN。
5、应用处理器向调制解调器发起获取当前注册的PLMN的请求；
6、调制解调器返回当前注册的PLMN给应用处理器；
7、应用处理器判断当前是否为漫游状态，如果不是，则保存当前注册的PLMN至PLMN列表(PLMN List，即上文中的第二列表)中；
8、当用户需要上网时，使用HPLMN与数据库中的保存有PLMN与APN对应关系的列表(即上文的第一列表)进行匹配；
9、若匹配的APN为空，则遍历PLMN列表，将PLMN列表中的PLMN与数据库中的保存有PLMN与APN对应关系的列表进行匹配；
10、使用匹配到的APN向网络侧发起PDP上下文激活请求，以获取网络数据。
举例来说，假设终端的USIM卡中的HPLMN为46020，终端中的第一列表中预设有PLMN1(46021)与APN1的对应关系和PLMN2(46022)与APN2的对应关系，其中，46020、46021及46022为EPLMN(Equivalent Public Land Mobile Network，等效的 PLMN)，如果PLMN列表中包括PLMN1及PLMN2，则终端发送给网络侧的PDP上下文激活请求中会包括PLMN1或者PLMN2。
可以理解，本申请实施例提供了一种APN匹配方法，当HPLMN所匹配到的APN为空(即没有匹配到对应的APN)时，使用第二列表中已成功注册过的PLMN进行APN匹配。通过上述方法，极大的增加当运营商增加新的PLMN时，终端中用于存储运营商PLMN与运营商PLMN对应的APN信息之间关系的列表中没有存储新增的PLMN或者当终端出现异常时APN匹配成功的概率，且能同时适应5G、4G、3G及2G等，可靠性强。
