背景技术
随着3G(Third Generation，第三代移动通信技术)/4G(Fourth Generation，第四代移动通信技术)等移动网络的快速发展，支持单或多3G/4G卡的终端可以预见将会以爆炸式的方式增长。移动网络数据业务已成为智能终端必不可少的关键业务。终端使用移动网络上网必然要用到APN(Access Point Name，接入点名称)。
APN指一种网络接入技术，是通过终端(例如手机)上网时必须配置的一个参数，它决定了终端通过哪种接入方式来访问网络。
对于终端用户来说，可以访问的外部网络类型有很多，例如：因特网(Internet)、WAP(Wireless Application Protocol，无线应用协议)网站、集团企业内部网络、行业内部专用网络。而不同的APN，所能访问的范围以及接入的方式是不同的，网络侧如何知道终端激活以后要访问哪个网络从而分配哪个网段的IP呢，这就要靠APN来区分了，即APN决定了用户的终端(例如手机)通过哪种接入方式来访问什么样的网络。
不同的运营商其APN配置信息是不一样的。定制的项目，运营商会提供其对应的APN信息。APN的关键参数很多，如APN、IP类型(type)、APN type等等；例如安卓(Android)支持的APN类型(APN type)有default、mms、supl、dun等等。
目前市场上手机或其他终端只要数据开关处于打开状态，都是需要建立无线数据网络，而且首先默认建立internet的数据连接。建立数据连接就需要选择APN。选择APN的方案是Android的框架层根据终端中SIM卡(Subscriber Identity Module，用户识别卡)中的MCC(Mobile Country Code， 移动国家码)、MNC(Mobile Network Code，移动网络码)以及SPN(Service Provider Name，运营商名字)等参数作为筛选条件，从预置的APN数据库中筛选出所有符合此SIM卡MCC、MNC、SPN等参数的APN。然后，按照数据库中的顺序从序号小的开始选择一个支持Internet上网的APN(也即默认APN)，建立默认的internet数据连接，并把连接成功状态上报给应用层。当某个应用需要上网时，首先查询此应用所需的数据连接是否存在并且是否是连接态，如果存在并且是连接的，就是使用该连接上传下载数据，达到上网的目的；如果此应用查询连接不存在或者状态为断开，则直接上报给用户，断网状态。
目前常用的通信应用(如浏览器、微信等)都是使用internet数据连接，当这些应用需要上网时就查询internet连接是否为连接态，决定是否能上网；这类应用可以直接使用采用默认APN建立的数据连接。但还有一些应用不能使用默认的APN建立的数据连接，此时尝试失败后需要为这类应用重新选择对应类型的APN建立数据连接供这类应用使用。例如，对于一些不能使用默认APN建立的数据连接的应用，其开启时，先尝试用默认的APN建立的数据连接，尝试失败时再从根据符合终端SIM卡的APN中查找出一个支持该应用的APN建立数据连接，供此应用使用。而目前手机等终端所支持的SIM卡越来越多，例如双3G卡、双4G卡等等，因此，对于一个终端来说符合SIM卡的APN也越来越多，根据上述这种机制为应用重新查找到的匹配的APN的工作量也越来越大，效率越来越低。另外，对于一些应用，其可以使用默认APN建立的数据连接，但其网络质量并不好或并不是最好，而相关机制中该应用会一直使用该默认APN建立的数据连接，无疑会降低用户体验的满意度。
综上可知，目前终端建立数据连接时，不管当前运行什么应用，都直接采用默认APN建立数据连接，在应用开启时都是先直接使用默认APN建立的默认数据连接，然而，对于此应用来说，使用默认APN建立的默认数据连接可能不适用需重选或者并不是最优的选择，影响应用上网质量。也即相关终端建立数据连接过程中，存在建立数据连接时不根据当前应用选择对应的APN，导致建立的数据连接与当前应用不匹配的问题。
另外，目前对于终端中符合SIM卡的APN，终端中任意应用都可以调用，对于网络侧安全性差。例如Docomo运营商系统升级的服务器是专享服务器，对应的接入APN也是特定dun类型的APN。由于任意应用都可以调用该dun类型的APN，因此，如果某恶意程序调用该dun类型的APN建立连接就可连接到系统升级服务器，很可能造成系统升级服务器瘫痪。

本发明的实施方式
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，所描述的实施例只是本申请中一部分实施例，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做出创造性劳动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。
现通过具体实施方式结合附图的方式对本申请做出进一步的诠释说明。
第一实施例
本实施例根据不同通信应用的需求，可以先设置好通信应用所适配的APN的对应关系，然后在检测到当前有通信应用启动时，可以根据设置好的对应关系直接查找到当前启动的通信应用匹配的APN，相对相关技术中直接选用默认APN的方式，既能避免所建立的数据连接不能被通信应用使用，又能保证建立的数据连接是与该通信应用最为匹配的类型，保证通信应用有最好的上网质量。参见图1所示，本实施例提供的APN分配方法包括以下步骤：
步骤S101：设置包含终端的通信应用与APN对应关系的对应关系列表。
终端中包含总APN数据库，该总APN数据库包含支持全球每个运营商的APN的数据。需根据终端中的SIM卡的APN选择参数(包括但不限于MCC、MNC、SPN等参数)，从该总APN数据库中选择出与该SIM卡匹配的APN放到SIM卡APN数据库中。然后，为终端的每个通信应用从SIM卡APN数据库中选择对应的APN建立对应关系。
步骤S102：检测到终端中当前有通信应用启动时，根据预先设置好的对应关系列表查找该当前启动的通信应用对应的APN。
步骤S103：使用查找到的APN建立数据连接；这样可以最大程度上保证所建立的数据连接与当前启动的通信应用匹配，使得该通信应用最快速地获得最好的网络质量。
应当理解的是，本实施例中的对应关系列表中，一个通信应用可能对应一个或多个APN，一个APN也可能对应一个或多个通信应用。如图2所示， 通信应用1对应的APN有A、B，通信应用2对应的APN有B，通信应用3对应的APN有B、C。对应关系可根据终端中的通信应用类型以及APN类型等确定。
另外，应当理解的是，本实施例中的对应关系列表中可以包含终端的所有通信应用，也即终端中的每一个通信应用所对应的APN在该对应关系列表中都有明确的记载。本实施例中的对应关系列表中也可仅包含用户所关心的通信应用(以下称为目标通信应用)的APN对应关系。例如，假设终端中有10个通信应用，用户仅关心其中的4个，则该对应关系列表中仅包含这4个目标通信应用的APN对应关系；对于剩余的6个，则可默认其对应的APN就是终端中的默认APN，或者采用其他规则选择对应的APN等。
基于上述建立的对应关系列表，在通信应用启动时即可根据该对应关系列表最快、最准确地找到与该通信应用匹配的APN，进而使用该APN建立数据连接。但正如上所述，对于一个通信应用，根据对应关系列表查找到的对应APN可能是一个，也可能是多个。因此，在查找到对应的APN后，对于查找到的APN如何进行调用以保证最终调用的APN是与通信应用最为匹配的也是一个值得深究的问题。对此，本实施例在设置好上述对应关系列表后，还可进一步对对应关系列表中的至少一个通信应用(例如，对应的APN有多个的通信应用，或用户所重点关注的一些特殊通信应用等等，或列表中的所有通信应用)所对应的APN设置APN调用规则。此时，使用查找到的APN建立数据连接的过程如下：
在查找到对应的APN之后，判断该当前启动的通信应用对应的APN是否存在APN调用规则，如存在，根据该APN调用规则从查找到的APN中选择出目标APN，使用目标APN建立数据连接；如不存在，则根据相关机制或随机选择机制从查找到的APN中选择一个作为目标APN。
本实施例中的APN调用规则可包含APN调用顺序规则；当判断当前启动的通信应用对应的APN存在APN调用规则时，则根据APN调用规则包含的APN调用顺序规则，从查找到的APN中选择调用顺序为第一的APN作为目标APN。调用顺序为第一的APN为与该通信应用最为匹配的一个APN，该APN可以保证通信应用有最好的上网质量。
例如，对于图2中的通信应用1，其对应的APN有A、B两个，假设通信应用1使用A的上网质量最好，使用B的上网质量次之，则对应的调用顺序为A第一，B第二。
又例如，对于通信应用2，其对应的APN只有一个B时，也可对该通信应用2设置调用顺序，只是此时的第一就是B。
对于每个APN的调用顺序，除了上网质量这一考量因素外，还可根据具体需求结合其他的因素设置。
另外，对于相关技术中，针对每个APN，终端内的任意通信应用都可以进行调用而存在的安全隐患的问题。本实施例在设置好上述对应关系列表后，还可以对对应关系列表中的至少一个APN(例如运营商指定的特定APN或者用户指定的重点APN等)设置应用限制规则，使得只有满足该应用限制规则的通信应用才有权限对该APN进行调用。这样可以提升网络侧的安全性，进一步提升用户体验的满意度。此时，使用目标APN建立数据连接之前，所述方法还包括：对该通信应用的使用权限进行鉴权，鉴权的过程包括：
判断选择的目标APN是否设置有应用限制规则，如存在，判断该当前启动的通信应用是否满足该应用限制规则，如满足，允许调用目标APN；否则，禁止调动，并通知重选目标APN。
本实施例中的应用限制规则可为：APN仅供专用清单(也即白名单)中的目标通信应用调用；判断通信应用是否满足应用限制规则包括：判断当前启动的通信应用是否为专用清单中的目标通信应用；如是，则满足；否则，判定不满足，当前启动的通信应用没有权限进行调用。
例如，当对于图2中的通信应用1既设定了APN调用顺序规则，又针对其对应的其中一个APN A(假设为排序第一的APN)设置了应用限制规则；则使用查找到的APN建立数据连接包括：
根据APN调用顺序规则选择排序为第一的APN A作为目标APN，判断出排序为第一的APN A设置有应用限制规则，则判断通信应用1是否满足该应用限制规则，如满足，则有权限进行调用，将该APN A作为目标APN；否则，表明无权限调用，需选择排序为第二的APN B重复上述判断过程。
上述示例是结合APN调用顺序规则和应用限制规则而进行的说明。应当理解的是，用户可以根据自己的实际需求选择设置上述两个规则中的任意一个或都进行设置，且其设置的对象也可根据具体的情况灵活选择。
本实施例中，设置好对应关系列表后，可对后续每个通信应用的实际使用情况进行监控，且可根据监测结果对设置的对应关系列表进行适当调整，以保证对应关系的准确性和最优性。例如，当发现终端启动某一通信应用，使用该通信应用对应的其中一个APN建立数据连接失败时，和/或，使用该通信应用对应的一个APN的网络质量反而没有使用其他APN的网络质量好时，都可对对应关系进行适当地更新调整。说明如下：
监测到使用通信应用对应的一目标APN建立数据连接失败时，表明该APN与该通信应用并不匹配，对对应关系列表中该通信应用所对应的该目标APN进行删除更新；
监测到使用通信应用对应的一目标APN建立数据连接后，该通信应用使用其他APN(可能是该通信应用对应APN之外的，也可能是对应APN中的一个，但不是排在第一的)的通信质量比使用该通信应用的目标APN的通信质量好时，将该APN替换为目标APN，也即将该APN作为新的目标APN。例如将该APN放置在对应关系的第一位。
对于一些终端，根据其上网设置情况，可能会在开机启动后就需要建立数据连接，此时建立数据连接时往往是选用默认APN建立数据连接。因此，本实施例中，当对于当前启动的通信应用，根据上述对应关系列表和/或调用规则选择出目标APN后，可以先判断终端当前已建立的数据连接所使用的APN是否就是该目标APN，如是，则直接使用该数据连接，这样就不需要重新建立，可节省资源，提升资源利用率，并同时提升联网效率。如当前已建立的数据连接所使用的APN不是该目标APN，则使用该目标APN重新建立数据连接以供通信应用使用。
第二实施例
本实施例提供了一种APN分配装置，请参见图3所示，包括：
对应关系设置模块31，配置为设置终端的通信应用与APN对应关系的对应关系列表；
终端中有包含支持全球每个运营商的APN的数据的总APN数据库。对应关系设置模块31需根据终端中的SIM卡的APN选择参数(包括但不限于MCC、MNC、SPN等参数)，从该总APN数据库中选择出与该SIM卡匹配的APN放到SIM卡APN数据库中；然后，根据用户指令或其他指令或规律，为终端的每个通信应用从SIM卡APN数据库中选择对应的APN建立对应关系。得到的对应关系列表中，一个通信应用可能对应一个或多个APN，一个APN也可能对应一个或多个通信应用。
处理模块32，配置为检测到终端中当前有通信应用启动时，根据对应关系列表查找该当前启动的通信应用对应的APN；
连接建立模块33，配置为使用处理模块查找到的APN建立数据连接，以保证所建立的数据连接与当前启动的通信应用匹配，使得该通信应用最快速地获得最好的网络质量。
应当理解的是，本实施例中的对应关系列表中可以包含终端的所有通信应用，也即终端中的每一个通信应用所对应的APN在该对应关系列表中都有明确的体现。也可仅包含用户所关心的通信应用或一些特殊应用。例如对于对应关系为默认APN的这一类通信应用，在该对应关系列表就不进行统计，当一通信应用启动且该对应关系列表中未查找到该通信应用时，就自然表明该通信应用对应的是默认APN。
请参见图4所示，本实施例中的APN分配装置还包括：APN调用规则设置模块34，配置为对对应关系列表中的至少一个通信应用(例如，对应的APN有多个的通信应用，或用户所重点关注的一些特殊通信应用等等，或列表中的所有通信应用)所对应的APN设置APN调用规则；
所述连接建立模块33包括：
第一判断子模块331，配置为判断当前启动的通信应用对应的APN是否存在APN调用规则；
第一选择子模块332，配置为在第一判断子模块331的判断结果为是时，根据该APN调用规则从查找到的APN中选择出目标APN，使用目标APN建立数据连接；如不存在，则根据相关机制或随机选择机制从查找到的APN中选择一个作为目标APN。
本实施例中的APN调用规则可包含APN调用顺序规则；第一判断子模块331判断当前启动的通信应用对应的APN存在APN调用规则时，则第一选择子模块332根据APN调用规则包含的APN调用顺序规则，从查找到的APN中选择调用顺序为第一的APN作为目标APN。调用顺序为第一的APN为与该通信应用最为匹配的一个APN，该APN可以保证通信应用有最好的上网质量。
应当理解的是，对于每个APN的调用顺序，除了上网质量这一考量因素外，还可根据需求结合其他的因素设置。
对于相关技术中，针对每个APN，终端内的任意通信应用都可以进行调用而存在的安全隐患的问题。本实施例可对特定的或所有APN设置应用限制规则，使得只有满足该应用限制规则的通信应用才有权限对该APN进行调用。这样可以提升网络侧的安全性，进一步提升用户体验的满意度。请参见图5所示，本实施例中的APN分配装置还包括：应用限制规则设置模块35和鉴权模块36。
所述应用限制规则设置模块35配置为对对应关系列表中的至少一个APN设置应用限制规则；
所述鉴权模块36包括：
第二判断子模块361，配置为在第一选择子模块332使用目标APN建立数据连接之前，判断该目标APN是否设置有应用限制规则；
第二选择子模块362，配置为在第二判断子模块361的判断结果为是时，判断当前启动的通信应用是否满足该应用限制规则，如满足，允许调用所述目标APN；否则，禁止调用，并通知第一选择子模块332重新选择目标APN。
应当理解的是，本实施例中的APN分配装置可以灵活地设置包含APN调用规则设置模块34和应用限制规则设置模块35中的任意一个或直接包含这两个模块。
本实施例中，请参见图6所示，APN分配装置还包括：监测更新模块37，配置为在设置好对应关系列表后，对后续每个通信应用的实际使用情况进行监控，且可根据监测结果对设置的对应关系列表进行适当地调整更新，以保 证对应关系的准确性和最优性。例如，当发现终端启动某一通信应用，使用该通信应用对应的其中一个APN建立数据连接失败时，和/或，使用该通信应用对应的一个APN的网络质量反而没有使用其他APN的网络质量好时，都可对对应关系进行适当地更新调整。
对于一些终端，根据其上网设置情况，可能会在开机启动后就需要建立数据连接，此时建立数据连接时往往是选用默认APN建立数据连接。因此，本实施例中，当对于当前启动的通信应用，根据上述对应关系列表和/或调用规则选择出目标APN后，可以先判断终端当前已建立的数据连接所使用的APN是否就是该目标APN，如是，则直接使用该数据连接，这样就不需要重新建立，可节省资源，提升资源利用率，并同时提升联网效率。如当前已建立的数据连接所使用的APN不是该目标APN，则使用该目标APN重新建立数据连接以供通信应用使用。

步骤S801：当SIM卡识别以后，读取手机中SIM卡的APN选择参数(包括但不限于MCC、MNC、SPN等参数)；
