问题

打开数据开关后，没有data PDN请求发起，因此无法上网。

根据日志确定是没有找到合适的data profile，原因一般有：

1、APN 没有配置

2、APN 类型/网络能力不满足——APN type或bearer

3、APN 配置了但被disable了——APN proofile的carrierEnable值

日志分析

fail log：

APN 被disable了，所以无法匹配。

//preferred=true说明当前选中的是此条APN

排查接口

canBeSatisfiedBy in TelephonyNetworkRequest.java -【frameworks/opt/telephony】

canHandleType in ApnSetting.java【frameworks/base/telephony】

匹配不到关键就是在网络能力评估的过程，canBeSatisfiedBy会根据APN类型筛选能力匹配的项，在canHandleType检查完APN可用性之后，返回enable且符合网络的APN。

定位原因的方法

查看APNSettings配置是否正确，以上问题就是APN配置了但被disable了。

[DataProfile=[ApnSetting] INTERNET, 3080, xxxxxx, internet, , null, , null, null, 0, supl | hipri | default, IPV4V6, IP, false, 0, true, 0, 0, 0, 0, 0, gid, xxxxx000000000000, false, UNKNOWN, UNKNOWN, 0, -1, -1, false, 961, TrafficDescriptor={mDnn=internet, null}, preferred=true]

根据ApnSettings实体节后打印信息，mCarrierEnabled就是上述日志false的位置。
