Location number and Location info in IDP message

How does IN charge a customer while roaming ?

I read some document about this and found that IN charge by 'location information'. Is this correct ? And this is a standard ?

The parameter shows in 'Location number' is MSC ? And the parameter shows in 'location information' is VLR GT ?

'Location number' is importance or not ? As I found some IDP without 'Location number', it fail !!
