What is a Usage to be considered?

    Dear colleagues,

    I am in the process of mapping our business objects to the entities contained in the open API TMF635 "Usage Management" and I have trouble understanding how to incorporate recurring fees into the data model. I understand Usage is "An occurrence of employing a Product, Service, or Resource for its intended purpose, which is of interest to the business and can have charges applied to it.". As such the usage should also represent a recurring fee created by our rating engine on a recurring basis. In that case, however, a RatedProductUsage would immediately be associated with the Usage, as there is no representation of the unrated recurring fee in our systems.
    Is my understanding correct?

    Thanks a lot in advance for your thoughts on this.

    Hi Carsten
    In the Open API model, a recurring fee is modeled as a ProductPrice (in the inventory), derived from a ProductOfferingPrice (in the catalog).
    These are visible in the respective APIs (TMF637 and TMF620).
    The existence of such a fee will eventually cause an AppliedCustomerBillingRate (ACBR) to be generated onto the periodic bill (TMF678).
    Usage is not the same as recurring - in the case of very fine-grained usages (e.g. telephone calls) - the usage records will be rated and aggregated into ​ACBR, while coarse-grained usages (e.g. consuming digital content) could be considered in some billing models as individual one-time charges.

    You can of course model a usage allowance that gives e.g. 100 SMS messages per billing period, for which a recurring charge of 2 Euro is paid.

    Hope it helps
