This unit details the operational standard practices for the various roaming environments. In particular, the use of roaming signaling for authentication and authorization, the postpaid business model and various means of credit management (HUR and NRTDE). Both of the two seperate models for prepaid billing - CAMEL and USSD will be discussed, and we will review the lifecycles associated with each of those operational practice areas.
