Understanding OSS: The Key to Network Operations and Maintenance

23 Jan 2023

Operations Support System (OSS) is a crucial aspect of any telecommunications network. It is the backbone of network operations and maintenance and is responsible for ensuring that the network runs smoothly and efficiently. But what exactly is OSS and why is it so important for network operations and maintenance?

What is OSS?

OSS, or Operations Support System, is a set of systems and software that support the management, operation, and maintenance of a telecommunications network. It is responsible for ensuring the network runs smoothly, efficiently, and cost-effectively. OSS includes a wide range of functions such as network planning, inventory management, and performance management. It also deals with the administrative and financial aspects of network operations through BSS (Business Support System). Together, OSS and BSS form an end-to-end solution for network operations and maintenance.

In today’s fast-paced digital world, networks are becoming more complex and demanding. OSS plays a vital role in ensuring that the network can handle the ever-increasing volume of data and traffic. It helps network operators to quickly identify and resolve any issues that arise, reducing downtime and ensuring that customers experience minimal disruptions.


In addition to OSS, another important aspect of network operations is Business Support Systems (BSS). While OSS deals with the technical aspects of managing a network, BSS deals with the business aspects such as customer management, billing, and revenue management.

BSS systems include Customer Relationship Management (CRM) systems, Billing systems, and Revenue Management systems. These systems are used to manage customer information, billing and invoicing, and revenue forecasting. They also provide important data on customer usage and behavior, which can be used to improve network operations and develop new products and services.

The integration of OSS and BSS systems is crucial for CSPs to fully leverage the capabilities of 5G-era networks and move into new business areas. OSS provides the technical capabilities to manage and optimize the network, while BSS provides the business capabilities to manage customers, billing, and revenue. Together, they provide a comprehensive view of the network and its customers, enabling CSPs to better understand their customers’ needs and develop new products and services to meet those needs.

Key Features and Components of OSS

The key features and components of Operations Support System (OSS) include:

  • Network planning and optimization: OSS includes tools and techniques for network planning and optimization such as traffic engineering, capacity planning, and network topology design. They ensure the network is designed and configured efficiently and can handle the expected level of traffic.
  • Inventory management: OSS is responsible for keeping track of all the network elements and their configurations and ensuring they are up-to-date and working properly.
  • Performance management: OSS includes tools for monitoring and analyzing network performance, such as fault management. These tools help network operators quickly identify and resolve any issues that arise, reducing downtime and ensuring that customers experience minimal disruptions.
  • Automation: OSS helps to automate many of the tasks involved in network operations and maintenance, such as network monitoring, troubleshooting, and provisioning. This reduces the workload on network engineers and increases the efficiency of the network.
  • Network Configuration: OSS includes network configuration management, which is the process of managing the entire process of deploying network devices, such as routers, switches, and servers.
  • Accounting: OSS includes financial management services like accounting, which ensure the network runs smoothly and efficiently.

Big Networks and How OSS can Help

As networks continue to grow and become more complex, the importance of effective OSS becomes increasingly vital. Big networks, such as those of Communications Service Providers (CSPs), require efficient management and monitoring to ensure smooth operation and optimal performance.

One of the key challenges in managing big networks is the sheer volume of data and information that must be processed and analyzed. OSS systems can help by providing advanced analytics and visualization tools that enable operators to identify and diagnose problems quickly and easily. This includes real-time monitoring of network performance, automated alarms and notifications, and Root Cause Analysis (RCA) tools to quickly identify the source of problems.

Another important aspect of OSS in big networks is automation. As networks continue to grow in size and complexity, manual management becomes increasingly difficult and time-consuming. OSS systems can help by automating repetitive tasks, such as provisioning, configuration, and troubleshooting. This not only reduces the workload on operators but also improves the speed and efficiency of network management.

Moreover, OSS can also help CSPs to increase their revenue by identifying new business opportunities and providing insights on customer behavior, network performance, and their network’s capacity.
