Nokia 5G Packet Core Architecture

Course Number: TT01368-V-1809
Course Duration: 5 days
Price: $3,425 US

Course overview

This hands-on instructor-led course explains the 5G end-to-end system architecture and describes the design and components of a 5G system which includes architecture explanations of Nokia’s solution for deployment option 3x and option 2.

It carefully examines the role and functionality of the components in the Next Generation Core (NGC). Students will also learn the procedures for access, mobility, session management, handover, and interworking with EPS, together with the concepts relevant to network slicing, the flow-based architecture of QoS, and 5G security.

The course is accompanied by comprehensive hands-on lab exercises using Nokia Cloud Mobility Manager (CMM), Cloud Mobile Gateway (CMG), and Network Resource Discovery (NRD) to reinforce the course learning objectives.
