The course focuses on PCC used with UMTS and EPS (with GTP-based core network). Relevant functional entities, protocols and interfaces are described, and signalling flows are used to illustrate the PCC mechanisms.


General knowledge about the architecture, terminology and modes of operation of the GSM/UMTS/EPS access and core networks is highly recommended. Basic knowledge of the Internet Protocol (IP) family is useful.
