What If a Postpaid user is in International Roaming and his credit limit has got Finished?

As we know that on basis of CAMEL contract, International roaming is possible, Visited-PLMN will generate the CDR at end and then forward it to home-PLMN. On basis of Call Data Records (CDR) home-PLMN will bill the user later in their currency.

The charging between the Operator's will happen as per the agreement.

So my Query is What if the user has crossed his credit limit during international roaming and ongoing call. How Visited PLMN will get to know about this information In between the ongoing call?
