Usage Management is the conduit for usage events of various types and formats from the different event generating functions like networks, applications, infrastructures, “Management and Control” etc. to various processes such as billing, legal compliance, and service assurance. Usage Event records are collected/processed, edited, correlated, enriched, formatted and distributed to upstream systems. It is not necessary that all usage events are always charged but might be used for enrichment of other usage events.<br/><br/>The Usage Management function supports various types of charging for sessions and events, for example, application instance, Max/Min usage based on flexible time intervals or active users of the application in both batch and real-time.<br/>
