[srslte-users] Codeflow for rrc.cc

Greetings srsLTE community,

I'm currently working on my Master's thesis in slicing an LTE network. What
I'm currently trying to do is to pass QCI information from the RRC layer to
the MAC layer. The way I approached it was to add a qci variable under the
UE class in the MAC layer, then I added a function to the existing MAC
interface for RRC to pass QCI from RRC to MAC layer. I would call this
function in rrc.cc in the get_drbid_config because that is where the QCI
value is extracted.

However, I don't think the function is ever called since I couldn't print
any output on the console. I'm not very proficient with C++, but I have
been catching up and reading a large portion of the code, and I assumed
that get_drbid_config function is called with the way eNodeB is setup since
drbs need to be assigned QCI values. Am I missing something with how the
code in rrc.cc flows?

I appreciate your support and apologize for the lengthy post.

Regards,
Ayman
