I would like to be able to simulate a GSM network in order to be able to develop and test an SMSC in an IP network. However, I don't have any BTS at the moment, and I don't know if I'll have one later.

It's not I want to learn about GSM, it's just I can't use openBSC itself. Since openBSC acts like BSC/MSC/HLR (if we have BTS), then it's theoretically possible to communicate with it (for instance from SMSC). That's why I asked the previous questions and I'll be pleased if someone could answer them. Thank you

Good question,

maybe it is better to ask the other way around. Right now it seems that you do
not want to use OpenBSC in itself but use it to learn about GSM. Is this
correct? What part of GSM are you interested in, what do you want to learn?
What is your motivation?
