VoNR: The evolution of Voice in the Era of Connectivity

In the ever-changing world of telecommunications, IMS and, specifically VoNR (Voice over New Radio) have taken on a key role in ensuring that voice calls can continue to function amidst in the rapid expansion of 5G networks. For these services to also be easy to scale, flexible and resilient, it is essential to use solutions that meet the CNF (Colud-Native Network Functions) criteria.

IMS: The foundation of the evolution of voice services

IMS (IP Multimedia Subsystem) is the IP-based architecture that enables the convergence of voice, video and other data services within a single infrastructure. This facilitates a smooth transition from older circuit-switched networks (2G/3G) to a completely packet-based architecture (4G onwards).

To harness its full potential, the optimal strategy is to implement IMS with a Cloud Native approach, using containers and microservices to enable better resource management, automated deployment, and dynamic scalability. IMS architecture based on CNF provides high availability and resilience, facilitating more efficient network use and reducing operational costs. This consequently leads to optimal consumption of resources.

The transition from VoLTE to VoNR with a Cloud Native infrastructure

VoLTE (Voice over LTE), already in the era of 4G, allowed operators to offer voice calls with higher quality than in 2G and 3G. Now, with the development of 5G, the so-called Voice over New Radio (VoNR) has arrived, operating directly on the new networks (5G).

• VoNR leverages the 5G architecture to deliver reduced latency and improved call quality.
• VoNR operates entirely on 5G spectrum and infrastructure. This means that operators can deploy voice services without the need to maintain active LTE networks, optimizing spectrum usage and improving network efficiency.

Deploying VoNR on a Cloud Native platform allows all its benefits to be amplified. Among the most prominent, it should be noted that operators can scale their services in an agile way, automate processes and reduce the time-to-market for new functionalities. This ensures an optimal user experience and more efficient network infrastructure management.

Benefits of VoNR and IMS in the Connectivity Era

The integration of IMS with VoNR and an infrastructure based on Cloud Native Network Functions (CNF) brings advantages for both operators and their customers:

1. Superior voice quality: VoNR provides high-definition calls with lower latency and better noise cancellation compared to previous technologies.
2. Increased efficiency: By operating entirely on 5G infrastructure, VoNR allows for better utilization of radio spectrum, eliminating the need to maintain multiple access networks simultaneously.
3. Scalability and automation: The implementation of IMS and VoNR on a Cloud Native architecture enables a dynamic scaling of services according to demand, optimizing costs and resources.
4. Lower energy consumption: Improvements in 5G network efficiency and the use of microservices-based solutions reduce energy consumption in devices and base stations, extending the battery life of mobile phones.
5. Resiliency and high availability: Thanks to CNF, IMS and VoNR can ensure continuous operation without interruptions, even in conditions of high demand or network failures.
6. Support for advanced services: Thanks to IMS, VoNR facilitates the integration of high-quality video calls, augmented reality, and unified communication with other data services.

The Future of Legacy Voice and Networking in a Cloud Native Environment

The future of telecommunications points towards a total convergence of IP services, legacy rees, where IMS plays a central role in the communication between legacy devices, applications and emerging services. The adoption of an IMS solution will allow a more efficient management of voice services, reducing the costs of maintaining legacy infrastructure, including fixed telephony.

In conclusion, the combination of IMS, along with an infrastructure based on Cloud Native Network Functions (CNF), is a crucial step in the evolution of telecommunications. This approach not only improves the efficiency and scalability of services but also prepares operators for the next generation of mobile network innovation, ensuring that voice and connectivity continue to evolve in the digital future.
