Network Operation and Maintenance Solution for Telecom Operators

With the accelerated popularization and application of the new generation of information technology, 5G, cloud and artificial intelligence are accelerating the arrival of the intelligent society, and the three major technologies are reconstructing the network. With the rapid advancement of my country's 5G industry, China Mobile, China Unicom, and China Telecom have accelerated their pace, and the era of full-service operations has arrived. The characteristics of the era of full-service operation are: large-scale network; more and more types of services. More and more people are beginning to enter the information communication network and use various information communication services such as entertainment, business, and trade. Once there is a problem with network security, it will definitely bring about very serious consequences. Therefore, in the process of gradually upgrading the IT operation and maintenance system, in addition to supporting requirements such as multi-service and integrated billing, it must also provide high-level security guarantees.

Pain Points of Network Operation and Maintenance for Telecom Operators

The arrival of the 5G era has brought a new business model to operators. With the development of operators' business, the service support network and service system are becoming more and more complex. The continuous increase of infrastructure such as network lines, network equipment, and cloud resources has made the entire network structure very large and complex; at the same time, with the increase of business systems, there are more and more business scenarios, and the business complexity is getting higher and higher . Under the traditional operation and maintenance management method, for the application of multi-segment network and multi-layer architecture, when a problem occurs, the speed of analysis, location and troubleshooting is relatively slow.

The specific performance is as follows:

1. There are a large number of IT infrastructure facilities, cloud, virtualization, etc. in the network of each telecom operator, and there are many types of equipment and equipment manufacturers, which are difficult to manage in a unified manner;

2. The equipment is mostly distributed in many large and small computer rooms, and the operation and maintenance management efficiency is low, and the decentralized construction of each system causes repeated construction and repeated investment, resulting in waste of resources and unnecessary increase in energy consumption;

3. As business systems are gradually migrated to the cloud, telecom operators have put forward higher requirements for cloud monitoring, and the current control coverage and means for the cloud environment and container environment are still insufficient;

4. There are many business systems and complex network structures in the telecom operator network, and it is difficult to locate problems in network equipment, servers, databases, middleware, distribution equipment, switches, storage, cloud, virtualization, applications, etc.;

5. In various scenarios such as layering, multi-vendors, and heterogeneity, the complexity of problem diagnosis and analysis is high, fault location and root cause analysis are difficult, and troubleshooting is time-consuming and laborious;

6. Operation and maintenance monitoring product capabilities are uneven, operation and maintenance data is scattered, lack of comprehensive data statistics and analysis, and effective linkage cannot be formed when analyzing problems and failures;

7. Lack of life cycle management of network assets such as IP addresses;

8. Operation and maintenance manpower outsourcing is common. Manual operation and maintenance + scattered tools lead to high workload, lack of flexible customization and use capabilities, and rely heavily on the experience of operation and maintenance personnel;
