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.
