How to manage multiple access networks

There are many access network methods in China and they are also widely used. It may be irrelevant for many people to know how to achieve diversified management of the access network. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. The trend of network IP is overwhelming, and mobile data services are becoming increasingly colorful. However, the complexity of network maintenance increases accordingly. Therefore, operators need to change from a device-type O & M model to a service-type O & M model.

Diversified Management of Access Networks

The original business transmission media of mobile networks is relatively simple. However, as mobile networks develop towards broadband, the accessibility of access methods is improved, and the base station coverage scenarios are more complex, with policy restrictions, factors such as wider coverage, increased cost pressure, and richer Use Cases of terminals have led to diversified access resources for base stations. Optical fiber, microwave, copper wire, and Ethernet may all undertake mobile bearer tasks. Therefore, maintenance and management of many bearer media will become a challenge that operators have to face.

Optimizing the management of group bearer Pipelines

The end-to-end IP address of the bearer network is one of the main objectives of the mobile network's end-to-end IP address. However, IP is a long-term process, so TDM and Grouping services will coexist in the network for a long time. Group businesses are characterized by traffic uncertainty and bursts. IP networks provide connectionless and best-effort services, which brings a lot of uncertainty to the management of bearer pipelines. The O & M experience of traditional SDH/MSTP networks must be inherited for IP-based bearer networks, and operators must improve end-to-end service management and quality monitoring capabilities.

Improve the intelligence of the network management system

The intensive coverage of base stations makes the number of 3G base stations about twice that of 2G base stations. However, in the initial phase of 3G construction, 80% of the 3G base stations can work with 2G base stations. While 3G carries network compatibility with 2G services, this compatible system should also be met in the maintenance system and network management system. This requires that the O & M system implement more complex and flexible configuration and supervision of multiple business forms under strict control of OPEX; provide a wide range of fault monitoring methods to prevent problems, at the same time, it can be accurately and quickly located to effectively solve user problems and improve user loyalty.

Progressive O & M Evolution

We know that the O & M cost is usually 3 ~ of the network construction cost ~ 4 times, mobile operators need to constantly focus on reducing operation and maintenance costs. However, most operators cannot accept major changes at the O & M level to protect investment and control costs. Therefore, network O & M can only evolve in a progressive access network that is "smooth.

Unified management to reduce maintenance boundaries

While the access network is becoming more diversified, if you only combine the network management systems supporting the technical direction, it will only increase the difficulty of O & M personnel and manually add maintenance boundary points, this leads to unclear responsibilities. Convergence will be the main direction for the development of network management systems. While implementing multi-element access network bearer management, the O & M boundary points caused by technical background are reduced, so that the mobile bearer network can be presented as a whole.

In addition, the Integrated IP mobile bearer network management system reduces technical barriers, shields network complexity, and reduces the skill requirements for O & M personnel. The original network management system can be smoothly upgraded to support the integration of O & M management, reducing the cost of network management investment caused by the introduction of new technologies.

Visual management. For more information about how to dial "Cloud", see routing.

With the development of mobile 3G services and wide coverage of networks, how the IP-based bearer network inherits the O & M advantages of SDH/MSTP bearer networks is a topic of continuous attention. For a long time, because the ip o & M mode is different from the bearer maintenance access network mode built by SDH/MSTP, the command line-based maintenance mode has increased the technical threshold of O & M personnel to a certain extent, this reduces the inheritance of O & M capabilities and lacks intuitive judgment on the network running conditions. Therefore, an IP network is like a group of "Clouds", and the internal routes are only known as "Clouds.

Telecom-level O & M requires visual access network maintenance. The mysterious "Cloud" in the IP network is decomposed and displayed in front of O & M personnel, so that the cloud is no longer confused. Through this access network method, the network can be better evolved from traditional passive O & M to active O & M, and the "soft" pipeline and maintenance indicators can be displayed in a graphical form to provide predictable maintenance of the bearer network, it provides enhanced support for mobile businesses.

O & M decoupling, changing as needed

The mobile bearer network infrastructure is large and distributed across a wide range of geographical spaces. Cross-region requirements are very obvious. networks in different regions are associated with each other to form a complex network structure. This requires the network management system to have a high degree of abstraction. Through full decoupling and abstraction, the managed objects are fully covered.

The loose coupling and distributed deployment capabilities of network management system modules are further improved, which can adapt to large-scale network management and assemble portable network management systems. In view of the features of mobile network maintenance, support single-site maintenance management, provide more maintenance means and greater flexibility for O & M management, meet O & M requirements across regions and CIDR blocks, and effectively increase the maintenance radius per person.

At the same time, due to the massive deployment of the PTN device, the DS-TE is configured on the network side through the rich configuration means of the network management system, and the hierarchical QoS service policy is configured on the user side, independent bandwidth allocation and supervision can be implemented for users' business flows, users, user groups, and physical ports to achieve unified allocation and supervision of network resources as a whole, provides more refined network resource allocation modes to comprehensively improve bandwidth utilization. Through hierarchical business-centric management modeling, the management complexity is reduced, and user, business, and bearer pipelines are associated and mapped. OAM enables end-to-end detection and maintenance, the Fault Locating time is shortened and the accuracy is improved. The root cause failure analysis and business impact analysis are more effective, making the access network that is close to the user for O & M and user-centered more fully realized.

Driven by various driving factors such as technology, competition, and Operation transformation, IP-based mobile bearer network management can only be switched from device-oriented to service-oriented, from distributed maintenance jobs to relatively centralized and highly centralized jobs, the management level is further reduced, from pure pursuit of network quality (QoS) to focusing on user perception (QoE ), from extensive management to intensive and refined management, from function management to process management, operators can be continuously improved in O & M efficiency, network profitability, and user perception, achieve a win-win situation between operators and users.
