Open APIs

Hi,

need your help to understand the difference between  Product Usage Vs Service Usage vs Resource Usage

TM Forum's Business Process Framework (eTOM) groups processes by domains (Product, Service, Resource, etc.) and the Information Framework (SID) and Open APIs are are also modeled around these domains. With the Usage Management API (TMF635) we may manage usage as reported by network elements, or ODA Components, within those domains.  While a 5G Converged Charging System (CCS) may be able to report Rated Product Usage a 5GC AMF, residing wholly within the Resource domain, would not and as such would report Resource usage.
