scope:

This Interim European Telecommunication Standard (I-ETS) specifies the management information model which covers the management aspects of the "usage metering information" function. The model specified in this I-ETS applies to the Operations System to Network Element (OS/NE) interface. The scope is further limited to the following priorities assigned for the scope of the work: - modelling of the requirements for the analogue, digital and Integrated Services Digital Network (ISDN) subscribers; - modelling of these subscribers requirements in connection with Intelligent Networks (INs). The scope of this I-ETS is also to give a list of elements needed to provide a complete usage information record to be utilized for charging and itemized billing and accounting. Collected data will be formatted and sent to the specialized centre (OS). The use of this data for other purposes, e.g. statistics, customer care etc. is possible, but out of the scope of this I-ETS. Usage metering in connection with operator assisted calls is out of the scope of this I-ETS. NOTE: The modelling of the charging and the billing processes is outside the scope of this I-ETS. Nevertheless, the usage metering record defined in this I-ETS may contain charge information if the calculation of charge is performed by the NE itself.
