MWC 2025: New Calling Innovates Voice Services in the 5G Era

MWC 2025: Shaping the Future of Telecommunications with New Calling

As we approach MWC 2025 in Barcelona, the spotlight is firmly on the telecommunications sector, particularly on innovations revolving around voice services. These services are integral to operators, playing a significant role in our interconnected world. Recent developments have highlighted the impressive growth of 5G technology, with a notable shift from older 2G and 3G networks towards fully maintaining 5G capabilities.

With over 5 billion users opting for Voice over LTE (VoLTE), its significance in 5G's voice and video services cannot be understated. As the industry transitions into the 5G Advanced (5G-A) era, New Calling emerges as a breakthrough that promises to dramatically enhance voice services, revolutionizing user interactions. At this year's MWC, Huawei will unveil its latest advancements in New Calling, emphasizing how these innovations empower operators.

The SVC4 Series: A Paradigm Shift in 5G Voice Networks

Huawei presents the SVC4 series of solutions designed to assist operators in constructing robust 5G voice networks. Notably, the Single Voice Core (SVC) is a pioneering solution capable of fully integrating voice services from 2G through 5G. This seamless transition is critical for operators aiming to provide consistently evolving voice network experiences. In tandem, Single Voice Roaming (SVR) facilitates circuit-switched roaming on VoLTE networks, a crucial component as the industry phases out legacy networks.

Moreover, Single Voice Insight (SVI) enhances network quality, while the innovative Single Voice Bypass (SVB) ensures that calls remain reliable, even amidst peripheral failures or data transmission issues. With the introduction of kite-like Session Border Controllers (SBC), Huawei guarantees that voice services remain consistently accessible, establishing a formidable backbone for the future of communication.

Global Expansion of New Calling Services

The concept of New Calling is rapidly gaining traction beyond China's borders. Operators like China Mobile are leading the charge, rolling out enhanced voice and video services, including features like Visualized Voice Calling and Real-Time Translation. By 2024, these offerings attracted a staggering 40 million users, prompting a strategic pivot from conventional voice services to more interactive, content-rich experiences. As we enter 2025, the market will witness an influx of terminals equipped to support data channels, allowing users to engage in interactive calls seamlessly—completely avoiding the need for dedicated applications.

The evolution of foundational models has paved the way for Huawei to launch an intelligent calling agent. This AI-driven service, built on the framework of New Calling, is designed to enrich user experiences and aid operators in transforming traditional dialing mechanisms into gateways for a variety of AI-powered services.

Collaborating for the Future of 5G-A

The advancement of communication technology requires the collective effort and investment from a wide array of stakeholders, including operators, equipment vendors, chip manufacturers, and industry standard organizations. Huawei is committed to collaborating with these entities to nurture the development of New Calling and foster an ecosystem beneficial for the telecommunications industry.

At MWC 2025, Huawei hopes to engage in substantial discussions with global partners, focusing on the innovative prospects for intelligent communications and the future trajectory of voice services. As the telecommunications landscape continues to evolve, the introduction of New Calling stands poised to redefine user interactions and operator capabilities in the fast-approaching future.
