Duration and Training Format
3-day instructor-led training
Course Objectives
The course describes in depth the technological solutions and standards that will enable the migration of telephony services over WiFi networks. After successful completion of this course, participants will be able to:
- Describe the network design and infrastructure for WiFi
- Describe the Voice over WiFi architecture
- Understand and describe the WiFi Calling
- Understand the trusted and un-trusted non-3GPP access
- Describe the Packet core infrastructure needed for Voice over WiFi
- Describe on how IMS is working and is related to delivering Voice
- Describe E2E signalling of SIP
- Describe the security related call-flow of a call.
- Understand mobility scenarios (WiFi – EUTRAN, ANDSF, MAPCON, IFOM, NSWO)
- Understand how to engineer WiFi for best possible VoWiFi Quality of Experience
Course Overview
The course provides a solid technical understanding of the Voice over WiFi technologies and architectures
endorsed by 3GPP, and the LTE industry. More specifically, the course covers in depth the procedures call flows as well as the necessary network optimizations required to deliver high performance & experience of voice service. The course contents goes beyond VoWiFi covering in depth WiFi Calling (VoWiFi) its call flows, handovers, and performance optimizations for a holistic and uniform packet based Voice service.
Key Benefits
Completing the course, participants will be proficient enough to be able to design, plan and optimize a best of class VoWiFi service that satisfy the current and future market requirements.
Pre-requisite for Participants
Basic knowledge of the IP. Basic understanding of 3GPP (preferably EPS, UMTS, LTE).
Who Should Attend?
Service Engineers, IP engineers, Radio and Packet core engineers, managers, project managers, Technical product managers, technical marketing officials, and technical strategy officials.
