5G新召唤：彻底改变通信服务格局-英-35页_6mb

Introduction and Overview

5G New Calling (5GNC) is an innovative service that enhances traditional voice and video calls with advanced features like augmented reality, intelligent interactions, and data sharing, leveraging 5G networks and the IP Multimedia Subsystem IMS. It aims to revitalize operator communication services by offering high-quality, secure, and immersive experiences, countering the decline from over-the-top applications. Key benefits include monetizing existing IMS infrastructure, boosting packet-switched technologies, and facilitating access to the metaverse and immersive communications.

Evolution and Advantages

The evolution of operator services shows voice and video calls as core elements, with operators maintaining advantages like global reach, device integration, carrier-grade quality, regulatory compliance, and transparent charging. 5GNC builds on this by introducing a phased approach, starting with enhancements on existing networks and progressing to IMS DC support for richer data interactions, enabling operators to reverse the decline in voice usage and offer competitive services.

Features and Use Cases

5GNC features include a new experience (ultra-high-definition, interactive calls), new capabilities (media and data integration via Mini-Apps), and a new ecosystem supporting New Calling Mini-Apps developed by operators, device makers, and third parties. Consumer use cases cover smart translation for language barriers, AR calling for enhanced visuals, and content sharing for real-time data exchange. Enterprise use cases include Enterprise Caller ID for verified business interactions and smart customer service for interactive IVRs and guided support, improving efficiency and user engagement.

Standardization

Standardization efforts by 3GPP and GSMA are crucial, with specifications evolving through releases like Rel-18 and NG.134 for IMS DC. This ensures interoperability, security, and alignment with network capabilities, fostering widespread adoption and integrating 5G strengths like low latency and AI.

Trials and Adoption

Global operators like Zain Kuwait and AIS Thailand are conducting proofs of concept, proving smart translation, interactive menus, and real-time services to boost user experience. China is advancing rapidly, with trials integrating advanced features and preparing for ecosystem rollouts.

Industry Impact

Collaboration among operators, vendors, and developers is key for a thriving 5GNC ecosystem. Efforts include shared APIs for innovation, joint trials at events like MWC, and plans to expand roaming and services, positioning 5GNC as a cornerstone for future communications and economic growth.
