Is it possible that MCC MNC gets changed in the same Diameter session without changing session ID while in Roaming???
As I have come to across an unsupported scenario when some users are roaming in Iceland operator MCC MNC and suddenly switch to different operator MCC MNC which belongs to the USA within the same DCCA session i.e without closing the PDP context and opening a new one (that should not be possible, unsupported scenario). Is it possible??? I'm confused here.

Will it be possible to send multiple CCR-I with same session id and different rating groups?

Hi,
I am unable to get some correct explanations for CCR-Initial.
Will it be possible to send more than one CCR-I with same session Id and different rating groups?

For example,
1.CCR-I with Request-Type = 1,Request-Number = 0 and Rating-Group = 10
2.CCR-I with Request-Type = 1,Request-Number = 1 and Rating-Group = 20

I tried to find the answer in RFC-4006,but didn't get any clue, or may be I am missing any clause or paragraph from that.
It will be great help if any standard RFC or 3GPP TS says about that.
