Thousands of companies hope that Nuggets 5G will make 5G development hot. But don't think that the biggest challenge of 5G development lies in business exploration. For network operation engineers, 5G network operation and maintenance also encounters many challenges.
In the 2G era, the mobile network almost only undertakes personal voice/message services, with single functions and good operation and maintenance; in the 3G/4G era, the mobile network also carries a large number of personal data services, which makes it more difficult for operation and maintenance personnel; in the 5G era, the mobile network does not only require Carrying billions of personal data needs, but also supporting the high requirements of digital transformation in thousands of industries, it is the digital base.
Precisely because it plays the role of a base, the stability and reliability of the 5G network are of vital importance. For example, for automated machines in factories, if the network is unstable, the entire production will be affected and economic losses will be caused; in the remote emergency consultation, if the network delay fluctuates, it will cause consultation errors and miss the best treatment period; With the arrival of autonomous driving, if network stability cannot be guaranteed, the popularization of autonomous driving will always be a dream.
Therefore, in the development of 5G networks, efficient operation and maintenance methods are required to ensure network reliability. In the past, we paid more attention to the operation and maintenance of 5G base stations and core networks. In fact, the 5G fronthaul network of the 5G bearer network is also one of the important links that operation and maintenance personnel care about. Many 5G fronthaul networks are passive, and it is difficult to predict and locate faults. What kind of 5G fronthaul deployment methods should operators use to improve network operation and maintenance efficiency and reduce costs?
The 5G era calls for efficient operation and maintenance
In the 5G era on the one hand, the emergence of new services puts forward higher requirements on network performance. For example, applications such as autonomous driving and telemedicine. On the other hand, the number of 5G network terminal connections has increased significantly. According to IDC forecasts, by 2025, approximately 55 billion devices worldwide will be interconnected via the Internet.
At this time, operators' traditional network operation and maintenance methods have long been overwhelmed. According to the OVUM analysis report, the revenue growth of the telecom industry has never outperformed the growth of OPEX in the past ten years. Among them, the operation and maintenance of the telecommunications network relies heavily on personnel experience and skills. On average, 300 engineers are required for the operation and maintenance of 10,000 devices in the telecommunications network, while only 3 engineers are required for OTT, which is a 100-fold efficiency gap.
For example, in the 2G era, when the network fails, the command center will issue instructions to the repair point before the repair point will perform repair work. If the fault is serious, the maintenance staff will not be able to work overtime, but it will take a lot of time to locate the fault point.
