Usage Information Model for Telecommunications Services over B-ISDN

This paper defines an end-to-end Billing Process Model. The processes in this model are mapped to the Telecommunication Management Network (TMN) Model. Usage Metering Interface (UMI) in the process model is defined for between Network Providers (NP) and Equipment Providers (EP). And it is designed for the BICI (Broadband ISDN Inter-Carrier Interface) environment where multiple carriers using ATM as underlying technology provide broadband services such as Frame Relay Service (FRS), Cell Relay Service (CRS), and Switched Multimegabit Data Service (SMDS). It also presents the detail contents of usage events over using B-ISDN services.
