Documenting Samsung Radio variables from the ServiceMode

Dear Baseband developers,

We are a very small group of XDA developers and external people trying 
to realize our Android based IMSI-catcher Detector (AIMSICD) project.

However, to realize such an ambitious feat we really need better access 
to the various RF variables and details of neighboring cells, among many 
other things. We have had partial success in that we're able to use the
ServiceMode (SM) menu from the Samsung ServiceMode application. However, 
this is just a wrapper to accessing OEM_RAW_REQUESTS presented by code 
that is part of the baseband FW. Now, the tricky part for us non-GSM 
experts, is understanding what these variables really mean and represent. 

I have started 2 threads on XDA to:

1) completely map out the ServiceMode menu options, for an GT-I9195 
(S4-mini) but should work on many similar and newer Samsung devices. 

2) To map out the various MM timers and many other RF/GSM variables 
shown and available in the SM menu.

We need help from the baseband community to understand the vocabulary 
used in this information as presented in (2) above, so that we can start to 
fill in the catcher-catcher detection parameters from the table here:

We will be using a modified version of this to do our detection. 

I'd also like to invite anyone interested to participate in this free and

You might want to look into https://github.com/2b-as/xgoldmon - maybe samsung devs
reused for s4 some of the names from s3

Yes, I have ran that already on my I9100, but that is specific for XMM
(XGOLD) modems and not possible (AFAIK) for Qualcomm modems, unless they
both happen to use the same debug output, which I doubt.
Second, xgoldmon requires the device to be connected and externally via
phone USB port, since the debug is coming directly from modem chip (CP) to
USB port, and not via AP kernel. So unless someone knows more about how
Androids are using RIL and modem RF debug output, that is not an option.
