MTKSST实现中handlePollStateResult()和pollStateDone()都会refreshSpn()刷新SPN区别于源码的 updateSpnDisplay()并且在上述两个state接口执行时就刷新时间比 updateSpnDisplay 还早。

registrationState 的值为 HOME 表示该设备已成功注册到本地运营商的网络即该设备正在其所属的运营商的服务区域内。networkRegistrationState 的值为 ROAMING 表示该设备正在漫游但是由于accessNetworkTechnology 的值为 UMTS 即设备使用的是 3G 网络因此这种情况下也可以视为没有漫游。roamingType 值为NOT_ROAMING说明非漫游。 日志 NetworkRegistrationInfo{ domainCS transportTypeWWAN registrationStateHOME networkRegistrationStateROAMING roamingTypeNOT_ROAMING accessNetworkTechnologyUMTS rejectCause0 emergencyEnabledfalse availableServices[VOICE,SMS,VIDEO] cellIdentityCellIdentityWcdma:{ mLac1134 mCid149649449 mPsc358 mUarfcn2959 mMcc214 mMnc03 mAlphaLongOrange SP mAlphaShortOrange SP mAdditionalPlmns{} mCsgInfonull} voiceSpecificInfoVoiceSpecificRegistrationInfo { mCssSupportedfalse mRoamingIndicator0 mSystemIsInPrl0 mDefaultRoamingIndicator0} dataSpecificInfonull nrState**** rRplmn21403 isUsingCarrierAggregationfalse}, 专业名词
