hi harald,
as i am still working on RR MM and CC layer, it seems to be more complicated as i thought.
remember all the messages in 04.08? but most problem is that i must first understand it
all. i get more and more knowledge about it while reading it. i started implementing some
parts, but most parts i do not understand yet. as i know from earlier project, it requires
exact knowledge of every bit to do it right.
when i am finished, i will tell you as soon as possible, but i think it takes some more
weeks. anyway, there will be many issues then. as i can see, there the layer 2 and layer 1
will also be not that easy too. e.g. layer 2 must process channel descriptions to connect
to the right channel and the right configurations and mode. also when i am finished, i
will need to solve some coding issues, like message flow, queueing (to prevent message
loops), and structures for subscriber data, telephone settings and system informations. as
soon i am finished, i will make a list of remaining unsolved issues.
and finally gsm 03.22 (selecting and changing cells) must also wants to be implemented.
if you like to be aware of what i am doing, just watch my code base. it is live, so every
time i do a write, it will be available at:

andreas
