Re: Complete setup with just simulation

For the GSM (voice/sms/ussd/...) side, connecting OsmocomBB with Osmo-BTS has been suggested several times. Instead of sending the messages over a real L1, you could send them over GSMTAP. Different ARFCN/timeslot/etc. can be encoded in the GSMTAP header, and you have nice debugging by the GSMTAP dissector in wireshark. I would guess that this can be done by a skilled developer in one week. For GPRS, a similar approach can be used. but: there is no MS-side implementation at all. You may be able to reuse higher layers like SNDCP and LLC from OsmoSGSN, as well as RLC/MAC message encoding and parsing from osmo-pcu. but you will definitely have to implement the full MS-side GPRS stack, mostly from scratch. We're talking about something in the oder of (few) months of development time.
