The reason is that I have not found anything in GSM08.08 that indicates > that the MSC will open a connection. Am I wrong with that? GSM 08.06 Chapter 6.1 Connection establishment: ii) the MSC decides to perform an external handover and a new dedicated radio resource has t obe reserved in the new BSS. The SCCP connection establishment is then initiated by the MSC So there is at least one case in which this procedure is being used. I know, we only do intra-BSC handover at the moment and no external handover is supported. But I think you might be interested in this anyway :) Regards, Harald -- - Harald Welte <laforge at gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
