This white paper analyses vertical use cases of various domains for their performance KPIs and their mapping to 5G network KPIs. The scope is to identify (based on architectural elements analysis, information flow, etc.) the potential impact on the service performance and user perceived quality. The challenge is to understand the relative influence of 5G network performance indicators to the vertical services. The KPIs mapping methodology includes three steps: - Research on definitions and information derived from the respective 5G-PPP projects, standardisation bodies and respective alliances e.g. ITU, NGMN etc., as well as definition of use cases from 5G-PPP projects' respective. - Identification of relevant key service KPIs and their definitions that are of importance to the respective industry. - Mapping of selected services KPIs on the respective network KPIs that impact the operation of the architectural elements that participate in the service provision process.
