V15.1.0 (Wzip)  2018/03  104 p.

Rapporteur:  Miss CHEN, SHAN

The present document studies the charging architecture, principles and functionalities for the set of features and capabilities supported by the 5G System Phase 1, and for interworking scenarios between the 5G System and existing systems. Evolution of charging mechanisms and charging models to support the Third Parties are investigated.
