Hello everyone,
thanks for the ideas you gave me about how i can learn more about the
communication between BSC and MSC in my sysmoBTS. Since last week i've been
looking at the source codes and it's still difficult for me to follow the
exchanged messages betwenn BSC and MSC. I don't have high programming skills.
Instead of using sysmoBTS as an autonomous self-contained GSM network (NITB
mode), i'd like to configure it in the BSC-only mode running the osmo-bts and
osmo-bsc. I read that i will need a MSC that can provide an A-over-IP interface
using SCCP-lite. I saw that the "on-waves/bsc-master" branch is implementing
such a SCCP and works have been done to create a GSM0808 like API and move the
MSC code inside OpenBSC over to use this API. So i was wondering how far this
project has been developed yet. Do you already have any interesting results
that can help me? If not, it can be also interesting for me to know how you did
your tests by implementing the bsc-only mode (osmo-bsc)? Did you connect it to
a real MSC or did you have anything else emulating the MSC/HLR/VLR/EIR
functions?
Best regards
Yann
