Concerning the BSC-MSC association, do we need to use an SG (osmo-stp) ? or could we establish a Point To Point BSC-MSC ? SUA ?
There is the SCCPlite variant of the A-interface, which osmocom supports, but it is not in any active use that I know of. See - 4.2.2.1 BSSAP/SCCPlite - 5.4.1.2 Configure SCCPlite in https://ftp.osmocom.org/docs/osmo-bsc/master/osmobsc-usermanual.pdf
I think you want to use osmo-stp when possible.
Concerning MGW, is there a way to use our MGW ? At this time, with Osmocom corposants, we can see RTP traffic between BTS-TRX and MGW, and some MGCP traffic between (BSC - local MGW) and MGW, and some MGCP traffic between osmo-MGW and osmo-MSC. Is there a way to have a "more standard" architecture: no traffic between BTS and MGW, and MGW controlled by MSC ? Do we have to more study TRAU, AoIP ?
Maybe familiarize with this chart: https://osmocom.org/projects/cellular-infrastructure/wiki/Osmocom_Network_In...
There is lateral MGCP between BSC->MGW and MSC->MGW, and RTP from BTS via the two MGW to the other call leg.
Concerning the Gb, do you think that it 'll work if we configure the Gb on a real SGSN connected to the osmo-pcu, hosted on the osmo-bts-trx?
it may work when you do the integration right =)
It would help if you were more specific, instead of "our MGW", "real SGSN".
