Whenever an UE attach to MME, MME updates UE's location into HSS by sending "Update-Location-Request" message. In this Diameter message, {Visited-PLMN} is a mandatory AVP . From HSS, by fetching this parameter value, it can be make out that where exactly the UE is present as of now. PLMN is the combination of MCC and MNC. MCC will say in which country it is roaming and MNC says which network is providing services.

M2M devices and data cards without voice services may not need an MSISDN, how are such records maintained on the HLR? Is it mandatory to have an MSISDN associated with every IMSI record on the HLR? If yes, can we just have a dummy/fake MSISDN associated in such a case so to avoid consuming/wasting a real MSISDN?

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?
