Re: [Openbts-discuss] Handover Implementation_openbts 3

[Dmitri S. <ds...@fl...>]

Hi Deepika,

the approach works well, and should be suitable for other versions. Please
note:
- it was implemented for OpenBTS 2.8 (that was pretty unstable), and
OpenBTS internal architecture essentially changed - it was not so easy to
follow it, taking into account that the official updates were a bit
unpredictable and git-ed in huge portions. It took me unreasonable efforts
to follow..
- as far as I remember, the key idea of handover implementation from Range
(by the end of 2013) was "freezing call state at the serving host as is and
moving it (over some protocol) to the new one, in a sort of a container".
Sorry for such an official re-telling
- there were some issues with processing re-Invite in Asterisk. I would
recommend to look at Freeswitch
