Summary of "Remonetizing Voice with Next-Generation 5G Voice and Video Services"

Core Content

This document outlines the transition of mobile network operators (MNOs) from traditional circuit-switched (CS) voice networks to 4G VoLTE and 5G VoNR. It highlights how 5G New Calling, built on the IP Multimedia Subsystem (IMS) and the IMS data channel, offers new opportunities to monetize voice services by enabling advanced multimedia communication features that can rival or surpass over-the-top (OTT) applications.

Main Viewpoints

• Transition to VoLTE/VoNR is unavoidable due to the end of life of CS networks, regulatory requirements, and the need for higher efficiency and better quality of service.
• IMS remains the foundation for voice and video services, supporting both 4G and 5G, and is a key enabler for 5G New Calling.
• IMS data channel is a powerful new feature introduced in 3GPP Release 16, allowing for bonded data and video channels, enabling real-time services and advanced multimedia applications.
• 5G New Calling is a native technology that allows for integrated multimedia services without requiring a device-side client, offering a competitive edge over OTT applications.
• Monetization potential is high with 5G New Calling, as it can support a wide range of value-added services such as AR, conversational AI, and intelligent translation, which can be integrated into both consumer and business applications.
• Deployment strategies are suggested in three phases, aligned with market readiness, user habits, and the evolution of the IMS network.

Key Information

Voice Network Evolution

• MNOs are transitioning from 2G/3G circuit-switched voice to 4G VoLTE and 5G VoNR.
• VoLTE and VoNR both rely on the IMS platform, which is already embedded in MNOs' networks.
• VoNR is expected to become the standard for 5G voice services, with 70% of mobile voice connections projected to use VoLTE or VoNR by 2030.

5G New Calling Overview

• Definition: 5G New Calling is a multimedia communication service based on the IMS data channel, allowing for the integration of data and video during voice calls.
• Features:
  • No device-side client required
  • End-to-end solutions
  • Ecosystem enablement via capability exposure
  • Integration of conversational AI, AR, and avatars
  • Unified and integrated service solutions

IMS Data Channel

• The data channel allows for the bonding of voice and video channels, enabling richer communication services.
• It supports real-time features like automatic translation and transactions, and can be used in both 4G and 5G networks.
• The data channel uses the WebRTC protocol stack and can scale with available spectrum, providing better bandwidth for high-quality services like AR and VR.

Value Chain and Ecosystem

• The IMS data channel opens up a new value chain for MNOs, involving content owners, creators, server providers, and digital rights management.
• MNOs can offer wholesale content delivery to providers, enhancing their revenue streams.
• The use of standardized APIs and commercial relationships is key to maximizing revenue from the ecosystem.

Business and Consumer Use Cases

• Consumer: Enhanced caller ID, scam detection, AR-enabled smart glasses, and home control.
• Business: Real-time translation, customer service automation, and integration with smart home and IoT devices.
• Government: Improved citizen services with AR and AI-based translation for migrant populations.
• Gaming and Entertainment: AR and virtual avatars can enhance the user experience in multiplayer gaming and interactive calls.

Deployment Phases

• Phase 1: Video-based New Calling deployment with minimal core network changes.
• Phase 2: Data channel-based deployment requiring IMS support for DC capabilities.
• Phase 3: Full DC deployment with AI and XR capabilities, enabling immersive services.

ZTE 5G New Calling Solution

• ZTE’s solution is based on IMS and includes support for the IMS data channel.
• It introduces cloud-native network elements such as DCSF, IMS AS, MF, DC AS, and AI MCP.
• These components enable the delivery of advanced multimedia services, including real-time translation and AI-driven media processing.

Conclusion

5G New Calling represents a significant shift in the way voice services are delivered and monetized. By leveraging the IMS data channel, MNOs can offer enhanced multimedia services that integrate with AI, AR, and IoT, creating new revenue streams and improving user experience. The phased deployment approach allows for a gradual rollout, ensuring alignment with market and user readiness.
