SCP(service control point)je parle pas de SCCP protocle.
if the IAM is sent from the MSC where the mobile is located,why ,i can see the international carrier for the home PLMN in the traces(ISUP traces) taken in home PLMN?

I don't have this problem - my phone is not allowed to roam - I keep it in my pocket!

Camel is for prepaid not for call set up or clearance.
ISUP comes in SS7. IAM originates at the MSC where the basestation picking up the signal is located. SCCP will have been used long before the call, during the location update. I think y are confused about the protocols and when they are used.
