Hi guys,
While analyzing attach failure in a 3G network i find many failures with cause 'SCCP connection refused (end user originated)' sent from the SGSN toward the RNC after a 'L3 GMM attach request, follow on request', these failures affects only few cells, and i'm really confused why it's happening for these cells while the failure is sent from the SGSN.
Any explanations for this behaviour?
