Hello all, I want a confirmation.
I 've seen in openBSC features that openBSC handles handover between cells inside one BSC. So I think it's possible to connect several nanoBTS to openBSC and move from one cell to another without losing the outgoing call. Am I right ?
Thank you. Chris

Yes, you are right. Please note, you need to use the --rtp-proxy option of osmo-nitb, as hand-over support is only enabled if the RTP data passes through OpenBSC, it can no longer be routed directly between the BTS's.

Yes, there is one bug in the RTP proxy code though. When we move the call we get a new RTP stream (sequence numbers, SSRC...) and our patching seems to add a lag. At public installations (congress) we have not suffered from this as LCR was handling this for us.
I understand, thank you both of you.
