The present document studies the charging aspects to better support vertical scenarios, which is different with the existing customer charging baseline, specified in
TS 32.240, and makes the evolution of charging specifications clearer, which focuses on studying the charging principles and references of verticals charging, and aims to provides an guideline for other charging management TSs that specify the verticals charging.
All terms, definitions and abbreviations used in the present document, that are common across 3GPP TSs, are defined in the 3GPP Vocabulary,
TR 21.905.
