Interesting, SCTP on the Abis link is new for me. openbsc (or osmo-nitb) has long been deprecated. The new programs to use are described here: https://osmocom.org/projects/cellular-infrastructure/wiki/Osmocom_Network_In_The_Box All of our currently supported 2G BTS models connect to OsmoBSC via TCP/IP (Abis). SCTP is supported for the A interface (between BSC and MSC), and for Iuh serving 3G cells, but not for 2G BTS to connect to the BSC. And just to make sure we're not confusing things: since your filename is 'hnb.zip' and your pcap contains Iub Signalling, it looks to me like you are trying to connect a 3G cell? We have SCTP support for attaching hNodeB to the osmo-hnbgw -- this is not Abis, but the Iuh interface. There is no "OsmoRNC" program yet (and probably won't be any time soon), so the only way to run 3G with Osmocom CNI is to use an hNodeB femto cell that already includes the RNC and talks Iuh to osmo-hnbgw (or operate your own RNC that talks IuCS to osmo-msc and IuPS to osmo-sgsn, which has never been tested before). I hope this clarifies things? ~N -------------- next part -------------- A non-text attachment was scrubbed...
