Hi Many many thanks to you, Pau & Neels
Sorry for my unclear questions.
The fact is we want to test to integrate Osmocom with some Ericsson nodes: MSC, MGW, SGSN
If we understand well, concerning the link between BSC and MSC, an OSMO-STP is the best solution (link SCCP M3UA / declaration of AS, ASP, RK, CP, ...)
Concerning the Gb, the link with the SGSN may work. Perfect !
Concerning the CP and UP of the MGW Ericsson and MSC Ericsson, sorry for my misunderstanding, what do you advice us ? if we look to the schema, do we need an Osmocom-mgw ? We presume Yes If Yes, Is it possible to just have one Osmocom-mgw hosted on the Osmocom-bsc ? In this case, There will be RTP traffic between Osmocom-bts and Osmocom-mgw (hosted on Osmocom-bsc) And there will be RTP traffic between Osmocom-mgw (hosted on Osmocom-bsc) and mgw Ericsson. And there will be MGCP traffic between Osmocom-mgw (hosted on Osmocom-bsc) and Osmocom-bsc.
Best regards Have a nice day
Jean-Marc
