功能背景说明
分析日志中关于AT “< OPERATOR” 的运营商名称信息来源。
04-22 22:53:25.915403 2140 2140 D RILJ : [0209]> OPERATOR [PHONE0]
04-22 22:53:25.922854 2140 2157 D RILJ : [0209]< OPERATOR {telering, telering, 23207} [PHONE0]
与MD交互，RILJ和RIJD（RIL_REQUEST_OPERATOR）
根据ril.h的注释说明，该信息是EONS的（Enhanced Operator Name String），即EF文件信息。
EONS信息来源：
- EF_PNN(PLMN Network Name, fid: 6FC5) ：LAC和EF_PNN中的Record Identifier
- EF_OPL(Operator PLMN List, fid: 6FC6) ：Network Name，具体名称
Code in SIMRecords.java getEonsIfExist()
因此< OPERATOR {long Alpha, short Alpha, MCCMNC}
