With Global large-scale deployment of 5G networks in the past few years, the growth rate of 5G users
has slowed down recently. At the same time, the introduction of new video coding algorithm and the peak MOU of mobile users in some areas lead to a slow growth of mobile network traffic. As a result, carriers begin to face slow revenue growth pressure and start to explore from traffic monetisation to experience monetisation transformation.
5G deployment enhances operators’ capabilities to provide differentiated services. The Network Data Analytics Function (NWDAF), which integrates Artificial Intelligence (AI) capabilities, solves key difficulties in experience operation, such as accurate identification of users and services, accurate service experience, and dynamic and timely assurance of user experience. It is a key help for carriers to transform from traffic to experience monetisation.
AI-enabled Intelligent Packet Core (IPC) network has a wide range of business scenarios: such as Cloud Gaming, Video Conference, and Live Broadcast assurance, and can also provide Smart High-Speed Rail Experience Upgrade. In addition, it can be used for Large Events assurance and vertical industries such as manufacturing, Transportation in the future.
The NWDAF, a key Network Element (NE) for experience operation, has been defined in 3GPP specifications. The NWDAF is introduced in 3GPP Release 15 to provide differentiated services and is continuously enhanced in R16 to R19. The dynamic UE logo that enhances user experience has been defined in the GSMA TSG WG. Here is still no unified global standard for service experience evaluation, which needs to be jointly developed by the industry together.
Carriers need to enable intelligent packet core networks step by step. First enable basic network intelligence capabilities and build a closed-loop system for real-time and dynamic user experience. then Introduce native AI to form a closed-loop system for experience operation.
World-leading operators have started to explore the business monetisation of Intelligent Packet Core. Such as AIS, CMCC, e& UAE, Globe, STC, Vodafone, Zain KSA, KT has started commercial use, trial, and PoC (Proof of Concept).
In order to let the IPC fully unleash the potential of 5G and monetise 5G, there is a need to continue to cooperate with the industry to solve the following issues:
- Enhance device and network collaboration to improve service experience;
- Build a global unified experience evaluation system and have a unified measurement standard for experience;
- Continue to explore new scenarios and business opportunities for network intelligence.
