During the transition to full 5G coverage, EPS fallback is used as a mechanism that allows devices to revert to 4G LTE for voice calls when 5G NR coverage is limited, ensuring seamless voice continuity before VoNR becomes widely available.

This evolution is not just about better call quality; it also enables enhanced integration with emerging technologies. For instance, VoNR supports real-time applications like virtual reality and advanced IoT devices, offering a more immersive and interconnected experience. As mobile networks continue to evolve, VoNR represents a foundational technology that will drive future innovations in communication, ensuring users have access to more efficient and reliable voice services.

Technical Aspects of VoNR

Underlying Technology Explained

Voice Over New Radio (VoNR) relies on the sophisticated framework of the 5G network to deliver its enhanced communication capabilities. At its core, VoNR utilises the New Radio (NR) interface, which is a key component of 5G technology. This interface supports a wide spectrum of frequencies, enabling it to handle the increased data demands of modern voice services. Unlike older systems, VoNR operates independently of legacy networks, such as 4G LTE, allowing for a more streamlined and efficient process. It employs advanced codecs that compress and decompress voice data without sacrificing the sound quality itself, ensuring crystal-clear audio. Furthermore, the technology benefits from 5G’s network slicing capability, which allows for the prioritisation of voice traffic, reducing interruptions and improving reliability. This technical foundation not only supports superior voice communication but also facilitates the integration with other 5G-enabled services, creating a robust platform for future innovation.

In the IMS network, the P-CSCF acts as the first point of contact between the user device and the network, handling session initiation and security.

Network Architecture of VoNR

The network architecture of VoNR (Voice over New Radio) is purpose-built to deliver high-quality voice services and multimedia services over advanced 5G networks. At the heart of this architecture is the IP Multimedia Subsystem (IMS), which acts as the central hub for enabling voice calls, video calls, and a range of enhanced voice services. The architecture is composed of several key elements: the User Equipment (UE), such as smartphones or IoT devices; the Next-Generation Node B (gNB), which serves as the 5G radio base station; and the 5G Core Network, which orchestrates the flow of voice traffic and data. The gNB provides robust radio access, ensuring that users can connect seamlessly to the network, while the 5G Core Network manages the routing and prioritization of calls and services. By leveraging the IMS, VoNR supports not only high quality voice but also mission critical services and seamless communication across different devices and networks. This modern network architecture is what enables VoNR to deliver superior voice over new radio experiences, supporting everything from everyday voice calls to advanced video calls and real-time multimedia services.

Core Network Components in VoNR

The core network components in VoNR are essential for delivering the superior voice quality and reliability that users expect from next-generation mobile networks. Central to this is the 5G Core Network, which is made up of several specialized functions. The Access and Mobility Management Function (AMF) is responsible for registering users and managing their mobility as they move between different network areas. The Session Management Function (SMF) oversees the setup and management of communication sessions, ensuring that voice calls and other services are efficiently handled. The User Plane Function (UPF) provides the actual data path for user traffic, enabling high quality voice and fast data transmission. Working alongside these is the IMS Core, which includes the Proxy Call Session Control Function (P-CSCF), Serving Call Session Control Function (S-CSCF), and Interrogating Call Session Control Function (I-CSCF). These components coordinate the setup, management, and teardown of voice calls, ensuring faster call setup times, lower latency, and consistent voice quality. Together, these core network elements form the backbone of VoNR, enabling high quality voice services and seamless communication for users on 5G networks.

IMS Core and Its Role in VoNR

The IMS Core is a foundational element in the VoNR architecture, playing a pivotal role in delivering high quality voice services and multimedia services over 5G networks. As the central platform for managing voice calls, video calls, and mission critical services, the IMS Core ensures seamless communication between users, regardless of their device or network. It is composed of several key components, including the P-CSCF, S-CSCF, and I-CSCF, which work in concert to manage voice traffic, authenticate users, and route calls efficiently. The IMS Core also incorporates advanced security measures, such as Transport Layer Security (TLS) and Secure Real-Time Transport Protocol (SRTP), to protect the integrity and privacy of voice communications. This robust framework not only supports high quality voice and enhanced voice services, but also enables seamless integration with other networks and devices, making it possible to deliver reliable communication services for both everyday users and mission critical applications.
