On March 5, 2025, the 5G-A Core Summit was hosted by Huawei at MWC 2025. During the summit, Chen Haiyong, President of CS&IMS Domain of Huawei Cloud Core Network Product Line, delivered a keynote speech centered on Huawei's AI Calling solution. He stated that this solution can help operators with a transformation from AI-empowered to AI-native in the 5G-A era and build a service entry in the AI era. Operators will further explore the potential value of voice services, unlocking a brand-new path to business success.

As AI technologies advance, leading operators are adopting AI as their development strategy and utilizing AI to revamp the value chain and deliver unparalleled user experiences. By leveraging native dial pads, Huawei has proposed the AI Calling solution to help operators build the New Calling enabling platform, establishing a key entry to intelligent services.
SVC4: Helping Operators Build Innovative Fundamental Networks for New Calling
Fundamental network construction is the cornerstone of New Calling service innovation. According to Chen Haiyong, fundamental networks must be equipped with the simplified architecture, roaming capabilities, and high stability and reliability, as well as be able to deliver optimal service experiences. To fulfill these requirements, Huawei has launched the SVC4series of solutions —Single Voice Core (SVC), Single Voice Roaming (SVR), Single Voice Bypass (SVB), and Single Voice Insight (SVI) — to help operators build voice& video fundamental networks delivering extraordinary communications experiences, consolidate the innovative fundamental networks for New Calling, and build 5G voice networks. SVC is the world's first to fully converge 2G through 5G and fixed networks, helping operators to continuously evolve their voice networks. SVR applies CS roaming to VoLTE networks, making it a must-have when sunsetting 2G/3G networks. SVB ensures network reliability, even if there's a fault with peripheral equipment or data transmission. Lastly, SVI helps improve network quality and increase VoLTE adoption.
VC + DC: Reshaping Basic Services to Expand the User Base
New Calling that supports both Voice/Video Channel (VC) and Data Channel (DC) can revolutionize basic services and foster new user habits. This will expand the user base and promote large-scale deployment and commercial use of New Calling.
On the one hand, the video channel illuminates screens with rich personalized services like AIGC-based digital human, real-time translation, fun calling, and real-time voice-driven avatar. This transforms calling services from voice-only operations into content operations, significantly enhancing user experiences. Additionally, voice channel-based simultaneous interpretation can be used on terminals lacking video capabilities to improve the communication efficiency. On the other hand, DC upgrades the interaction mode of customer services from DTMF key-pressing to screen-touching. With just a few effortless taps, users can book meals and rooms, or receive real-time assistance remotely. In this way, enterprises can efficiently process business transactions through calls, thereby expanding their B2B market reach.
New Calling is now being put into commercial use around the world, with particularly strong adoption in China, where New Calling has drawn in tens of millions of users and a beta recruitment has been launched for DC-based New Calling services. Chen Haiyong views this breakthrough as a significant milestone in the development of the global New Calling industry, and believes that it will further propel the advancement of DC-based New Calling.
Calling Agent: Facilitating Transition from AI-Empowered to AI-Native and Unlocking New Business Opportunities
Empowered by AI, calling agents can now instantly perceive multi-modal interactions — including semantics, emotions, and intentions — allowing for seamless intent analysis and streamlined task orchestration. The calling agents consolidate multiple complex tasks into a single call to enable swift, closed-loop task management, significantly boosting call efficiency and convenience. Leveraging the extensive number resources of operators, industry agents can be accurately contacted. This helps operators build an open application ecosystem, shift from AI-empowered to AI-native, and capitalize on emerging service opportunities in the AI era.
Chen Haiyong concluded the speech by emphasizing Huawei's commitment to collaborating with industry partners, including terminal suppliers, chip vendors, standards organizations, and third-party industry partners, to drive New Calling innovation, bolster fundamental networks, and unlock fresh growth opportunities for the voice industry.
