规则简介

EONS也是更新PLMN，而不是SPN，SPN都是依据卡信息。

在MTK平台上，提供lookupOperatorName逻辑，根据SPN/EONS/NITZ刷新运营商名称显示内容，也可以自定义优先级。

流程接口

• [SST] refreshSPN 更新SPN =>
  • Note：MTK源码是通过lookupOperatorName，客制化加入config使之执行下述lookupOperatorNameWithConfig，区别只是多加了形参ruleConfig。
• [SST] getConfig 获取配置，确认是否有定制优先级 ——这与display rule没关系 =>
• [RILJ] lookupOperatorNameWithConfig =>
  • 可以自定义来源优先级，比如SA设备用5GEons： lookupOperator5GName 
  • [RILJ]  lookupOperatorNameEons
    • [SIMRecords] getEonsIfExist() 获取卡EF信息 
  • [RILJ]  lookupOperatorNameNitz
  • [RILJ]  lookupOperatorNameMVNO 获取TS25的配置，一般是上层spn-conf.xml文件，在MTK 6835平台由MD维护
• [SIMRecords]
