osmith gerrit-no-reply at lists.osmocom.orgHello Vadim Yanitskiy, Pau Espin Pedrol, Neels Hofmeyr, Harald Welte, Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/14096 to look at the new patch set (#2). Change subject: GSUP: document inter-MSC handover additions ...................................................................... GSUP: document inter-MSC handover additions Message formats of the new messages look mostly the same (IMSI, Message Class, Source Name, Destination Name, AN-APDU). That is, because AN-APDU is storing results, error reasons etc. This can be seen clearly in osmo-msc.git: * src/libmsc/msc_a_remote.c:msc_a_remote_fsm_communicating() * src/libmsc/msc_i_remote.c:msc_i_remote_fsm_ready() The message squence charts in the E Procedures section are directly based on Neels' interMSC_HO_GSUP_msgs.txt [1]. It seems that using AN-APDU made some other new IEs redundant: RR Cause, BSSAP Cause, Session Management Cause had been added to GSUP for the MSC handover, and are documented now, but they are currently not used in osmo-msc.git. The new message OSMO_GSUP_MSGT_E_ABORT is not used either, so I left a stub for it in the message format section. I mentioned in the Source Name IE section, that source and destination names are sent as nul-terminated strings. This is for legacy reasons, Neels wrote a nice summary in the commit message of [2].
