Telephony parameters not available through framewo

问题:

I have to fetch the info related to following Telephony parameters: BCCH, Band, DL ARFCN,UL ARFCN, BLER, MOS DL, MOS UL, Txpwr & Handover Parameters.

I searched a lot but didn't find any way to get this information through APIs. There may be some other ways (I am not sure), like:

1. Using AT command.
2. Using AIDL, talk to RIL & fetch the info.
3. Using NDK, write c code which will directly talk to modem/low level implementation.

But I don't know which is the right way or how to proceed with the right approach. Any help regarding any of the Telephony parameters will be highly appreciated.
