Intelligent network management for 5G
What is network management?
Network management is an integral part of mobile networks. It covers configuring, automation and optimization tasks as well as monitoring, analytics and troubleshooting. Network management needs to follow the rhythm of network evolution.
In mobile networks, the volume of data traffic and network complexity are increasing continuously. Many operators are running multi-vendor and multi-technology networks, which brings a further challenge from network management perspective. Network management must be able to tackle both the increasing network complexity and the growing amount of traffic and data.
A network management system consists of tools for handling various network elements in live network and also for the future network expansion. It offers a wide range of common operation and maintenance capabilities for network elements in core, radio and transport networks both for managing physical network elements as well as virtualized network functions.
Why is intelligence necessary in network management?
With the introduction of 5G, there are more network elements, sites, and cells than ever before. Managing the complexity of 5G in a cost-efficient way requires more than just automation. Machine learning brings the necessary intelligence for managing 5G networks, resulting in operational efficiency.
Managing multi-technology networks is time-consuming. It is not possible to manually handle all network management tasks in a 5G network without impacting subscriber experience. Furthermore, most network outages are caused by human error. Automated routines with machine learning algorithms help eliminate typical human mistakes. They also make introduction of new services faster. When the burden of repetitive network management tasks is moved to the algorithms, the operator’s network engineers can concentrate on more value-adding tasks.
Seamless network management also in 5G
With MantaRay NM, mobile network operators can easily handle the continuous growth of data. Its seamless management capability shows the biggest values when there are many technologies and layers in the networks. Nokia MantaRay NM functionalities are developed to take care of 5G from day 1.
This is also supported by the continuous introduction of premium features, for example zero-touch 5G rollout with Plug-and-Play functionality, mass base station rebuilding for smooth SRAN migration, or mass change verification on network elements.
Worlds first automated 4G/5G slicing in RAN domain
Nokia network management system is slice aware starting from 4G. Slice automation enables operators to streamline operations, thereby reducing operational costs and meeting expectations for service velocity. Nokia MantaRay NM is an integral part of Nokia‘s end-to-end 4G/5G radio slicing solution.
Our flagship network management system is providing both automated Configuration and Performance management for 4G/5G radio slices.
Machine learning in network management
Nokia MantaRay NM leverages big data and combines it with machine learning techniques for various functionalities. Being the central source of network-wide operations, MantaRay NM also provides a great source of input for other machine learning applications in CSP networks.
There are close collaborations ongoing between operators and Nokia on machine learning concepts and use cases, e.g. intelligent correlation of network alarms. These innovations help maximize the value of machine learning in network management.
Reduce radio network energy consumption without compromising the end user experience
70-80 percent of a mobile network’s energy is consumed by base station sites. Mobile operators face an overall increase of 10-30 percent annually in mobile network energy use. Managing energy efficiency is necessary to control the costs while maintaining the service level that end users are expecting.
MantaRay NM is part of Nokia's MantaRay Energy solution, which significantly reduces power consumption of radio networks, helping CSPs reach their zero-emission targets.
