Training - Evolved Packet Core

  • Duration: 2 Days 
  • Price: 1200 EUR (excl. VAT)

TECHNOLOGY FOCUS

3GPP does not only define a completely new air interface called Evolved UMTS Terrestrial Radio Access Network (E-UTRAN), but also an Evolved Packet Core (EPC) as part of the System Architecture Evolution. The latter represents a framework for an evolution or migration of the 3GPP system to a higher-data-rate, lower-latency, packet-optimized system that supports multiple radio access technologies (RATs). It is based on a flat, simplified all IP based architecture with a reduced number of network entities, a new Quality of Service concept,  and the support of seamless mobility between heterogeneous access networks. 3GPP has completed the standardisation; extensive trials are under preparation while services are expected to start around 2010.

COURSE CONTENT

This course provides a detailed understanding of the general EPC architecture and protocols that are part of the latest version of the 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) will be explained together with the underlying protocol stack. Special focus will be given on the Non-Access Stratum (NAS) signalling between a User Equipment (UE) in the E-UTRAN and the EPC network, as well as on the overall Quality-of-Service (QoS) concept. In addition, authentication, addressing, security and location management within the service area will be treated. A final aspect will be the 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).
