That is, because\nAN-APDU is storing results, error reasons etc. This can be seen clearly\nin osmo-msc.git:\n* src/libmsc/msc_a_remote.c:msc_a_remote_fsm_communicating()\n* src/libmsc/msc_i_remote.c:msc_i_remote_fsm_ready()\n\nThe message squence charts in the E Procedures section are directly\nbased on Neels' interMSC_HO_GSUP_msgs.txt [1].\n\nIt seems that using AN-APDU made some other new IEs redundant: RR Cause,\nBSSAP Cause, Session Management Cause had been added to GSUP for the MSC\nhandover, and are documented now, but they are currently not used in\nosmo-msc.git. The new message OSMO_GSUP_MSGT_E_ABORT is not used either,\nso I left a stub for it in the message format section.\n\nI mentioned in the Source Name IE section, that source and destination\nnames are sent as nul-terminated strings. This is for legacy reasons,\nNeels wrote a nice summary in the commit message of [2].\n\n[1] https://osmocom.org/attachments/3720/interMSC_HO_GSUP_msgs.txt\n[2] Change-Id: I9ca8c9eef104519ed1ea46e2fef46dcdc0d554eb (osmo-msc.git)\n\nRelated: OS#3774, OS#3619\nChange-Id: I6b9f23d08cfe53c8b77f51c6afb900c2badc9e2c","distinct":true,"url":"https://api.github.com/repos/osmocom/osmo-gsm-manuals/commits/db0564b763441b8ef2a9e5676e82d1fceb2a688f"}]}
