An Introduction to 5G Voice over New Radio (VoNR)

Explore the future of voice services with 5G New Radio (NR)! This course dives deep into Voice over New Radio (VoNR), the key to delivering high-quality voice calls in a 5G environment.

Understand how IMS (IP Multimedia Subsystem) is the foundation for 5G voice, mirroring its role in 4G networks. We'll break down the core concepts and driving forces behind VoNR, including the crucial work of major standards bodies.

Key topics covered:

• VoNR Architecture: Learn the essential components of a VoNR deployment, including the 5G NR access network, the IMS Call Control network, and the Policy and Charging Control (PCC) framework. Discover how these elements work together.
• Initial Access Procedures: Follow the steps a device takes to connect to 5G and register with IMS for voice services.
• Call Establishment: Delve into the technical details of VoNR call setup, including codecs, media packetization, and a simplified overview of SIP (Session Initiation Protocol) message exchange.
• Interworking & Fallback: Explore how VoNR integrates with existing voice networks, including legacy voice services. We'll also cover handovers, Wi-Fi Calling, and EPS (Evolved Packet System) fallback mechanisms for seamless connectivity.

This course is essential for anyone looking to understand the technical aspects of 5G voice, VoNR implementation, and the evolution of mobile communication. Gain a comprehensive understanding of how 5G NR is transforming the future of voice communication.
