Description

In the current osmo-hnbgw implementation, we simply configure the hNB RTP data to go directly to the MSC (or it's MSC-colocatetd MGW). This requires IP-level routing between the RAN and the CN, which is possible in most lab situations, but not possible in real operator networks.

So we'd need to add support for osmo-hnbgw to control a co-located osmo-mgw. So like osmo-bsc, osmo-hnbgw would have to manage endpoints on osmo-mgw. This way there are separaet RTP flows:
  1. between hNodeB and osmo-mgw on the RAN side
  2. between MSC/MGW and osmo-mgw on the CN side
