I am Tiger. Glad to connect with you.From osmo-bts commitment I see you are working on dynamic PDCH which I think is a breakthrough. Is it working now? It looks like only support PDCH and Full TCH switch,right?
Hi Tiger,
thanks for your comments and enquiry!
I am still working on TCH/F <-> PDCH switching for the osmo-bts-trx SDR platform, but for ip.access nanobts, SysmoBTS and the litecell15, dynamic TCH/F <-> PDCH switching is already functional.
TCH/F <-> PDCH could be called the ip.access compatibility mode, as it uses ip.access vendor specific messages to activate and deactivate PDCH on a TCH/F_PDCH timeslot.
There are plans to include TCH/H as well, using a different vendor specific extension. Though development has not commenced yet, which will depend on funding by interested parties.
See: http://osmocom.org/issues/1565 http://osmocom.org/issues/1757
BTW, Tiger, you have contacted my private email address. Instead, I'm replying from my sysmocom address, Bcc to you and copying to our mailing list, which would be the most appropriate place for questions on osmocom development.
