TECHNOLOGY FOCUS
COURSE CONTENTS
This training course will provide participants with a detailed understanding of the general EPC architecture and protocols that form part of the latest version of 3GPP specifications. In detail, the course covers the architectural layout and the newly-defined network nodes in the Evolved Packet Core (EPC) network. All relevant interfaces between these nodes and the Enhanced UMTS Terrestrial Radio Access Network (E-UTRAN) as well as the underlying protocol stack will be explained. A special focus will be on Non-Access Stratum (NAS) signaling between User Equipment (UE) in the E-UTRAN and EPC network, as well as on the overall Quality-of-Service (QoS) concept. Moreover, authentication, addressing, security and location management within the service area will be treated. One final aspect will be coupling of the EPC network with previously standardized 3GPP radio access networks (e.g. the UTRAN) and other potential non-3GPP IP-based access networks (e.g. WiMAX).
