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,
