LTE Core Network |
Training Course Outline
Course Duration:
2 Days
Training Course Description:
The goal of the LTE SAE from the 3GPP is to achieve a
high-data-rate, low-latency, packet-optimised system that supports
multiple access technologies. Long Term Evolution, as defined in the
3GPP Release 8 standards, has described both an evolved Radio Access
Network (E-UTRAN) and a new core network strategy termed SAE -
System Architecture Evolution.
The main part of SAE is the Evolved Packet Core (EPC), otherwise known as the SAE Core. The new core network is key to achieving the level of performance that LTE must deliver with the sort of low delay across the network that has been hitherto unachievable with GPRS and UMTS.
Prerequisites:
Delegates need an in-depth understanding of LTE
