New Challenges of 5G Network
Challenge posed by complex network management: In the 5G era, the network scale will grow rapidly, the equipment scale is expected to grow by more than 10 times, and the service traffic will increase by dozens of times. Massive network management brings challenges to network CAPEX, OPEX, and network efficiency. Challenge posed by network resource efficiency maximization: According to Gartner's forecast, by 2022, network traffic will increase by more than seven times. With the rapid development of new services such as HD video calls, real-time teleconferences, and live VR sports broadcast，user requirements for traffic increase rapidly, user requirements for traffic increase rapidly, bringing unprecedented pressure to network resources. Challenge posed by experience-centric era: The 5G era is centered on user experience. High-quality user experience is the core factor for obtaining, keeping, and developing users. No matter for ToB or ToC services, the quality of user experience is reflected in the following aspects: simplified service provisioning, real-time service quality monitoring, imperceptible service fault restoration, and flexible service bandwidth adjustment.
