GlobalData Presents White Paper on Voice Service Evolution at MWC 2026

Insights into Voice Service Evolution

At the Mobile World Congress (MWC) 2026 held in Barcelona, Andy Hicks, a prominent Senior Analyst at GlobalData, unveiled a comprehensive white paper titled "Reinventing Voice: A Converged, AI-Enabled, and Multimodal Core for Next-Generation Telecommunications." This publication sheds light on how telecommunications operators can leverage a fully converged voice network to innovate AI-driven services, thereby redefining their value propositions in a rapidly changing digital landscape.

The white paper emphasizes that as artificial intelligence continues to evolve, it presents ample opportunities for innovation within voice services. Hicks articulated a three-phased approach where AI integration transforms how operators perceive and deliver voice services.

In the first phase, AI enhances overall conversation experiences, which offers operators a competitive edge against Over-The-Top (OTT) applications. Improvements such as intelligent noise suppression and advanced spatial audio effects elevate voice communication into a more immersive and sophisticated interaction. The result is not just crisper sound but also a communication experience that resonates with users, enhancing satisfaction and engagement.

The second phase involves infusing AI into audio channels, introducing revolutionary features like real-time translation and intelligent conversation summaries. These innovative functionalities do not impose additional demands on end-user devices, allowing operators to roll out these enhancements swiftly and solidifying their position as frontrunners in AI-based voice innovations.

Finally, in the third phase, AI integration expands beyond audio to include video and data channels, facilitating a shift from unimodal to multimodal services. This evolution allows operators to offer advanced solutions such as interactive customer support and virtual medical assistant services. Moreover, this phase brings forth the concept of "Call-as-a-Service," positioning voice communication as part of a broader service offering rather than a standalone product.

Hicks stressed the crucial role that operators must play in harnessing the power of AI. By leveraging a fully converged voice network as a solid foundation, they can foster service innovation and rejuvenate the core value of voice services while simultaneously evolving their technologies alongside 5G-A and AI improvements.

Fully Converged Voice Network: A Strategic Necessity

The introduction of a fully converged voice network becomes increasingly relevant amid the global transition towards containerization. It allows seamless transitions from virtual machines (VMs) to containers, enabling operators to lower their total cost of ownership (TCO) while ensuring a continuous stream of service innovations and quick updates to voice functionalities. This adaptability is vital, especially as 2G and 3G networks approach their lifecycle ends, compelling operators to maintain them to support essential services such as M2M communication and international roaming.

As the industry gradually moves towards 5G-A, the convergence of voice calls across various generations—2G, 3G, 4G, and 5G—will alleviate operational challenges associated with technology lifecycle management and pave the way for smooth future transitions in network standards.

By applying an architecture that facilitates voice service evolution, operators can combat the challenges presented by the dynamic landscape and position themselves as leaders in telecommunications innovation. The insights shared during MWC 2026 are not just theoretical; they constitute actionable strategies for operators aiming to adapt and thrive in an age increasingly influenced by artificial intelligence and advanced telecommunications frameworks.
