Functions of OSS (Operations Support Systems):


  • Network Monitoring and management

The system provides tools for real-time monitoring and management of network elements, including switches, routers, base stations and transmission equipment. This includes monitoring network performance, overall availability and fault detection to ensure optimal network operation.

  • Fault Management

OSS includes features for detecting, diagnosing and resolving network faults and performance issues. It provides alerts and notifications for abnormal conditions, facilitates fault isolation and supports troubleshooting to minimize service disruptions and anomalies.

  • Service Provisioning

OSS enables the automated provisioning and activation of services for customers. This includes the configuration of network resources, such as bandwidth allocation, service activation and subscriber provisioning, to support new service deployments or modifications and ensuring the services are delivered as promised to the customer.

  • Performance Management

Operation support systems collect, analyze and report on performance data from network performance metrics, such as latency, bandwidth and packet loss, to assess overall network health and performance. This includes monitoring key performance indicators (KPIs), identifying trends and optimizing network capacity and performance.

  • Inventory Management

OSS maintains an inventory of network assets, hardware devices, software components and logical network elements. It tracks the location, status and configuration of these assets to support network inventory planning for provisioning and maintenance activities, to aid in efficient resource allocation and capacity planning.

It ensures that the network operates smoothly, which indirectly impacts customer satisfaction.


BSS and OSS are crucial for the seamless delivery of services and efficient operations for a telecom company. Effective integration ensures that data flows smoothly between the technical and business systems, enabling a comprehensive customer service experience.

For example, when an order is placed, BSS handles the order processing and billing, through the order management system(OMS), which interacts with OSS to provision and configure the necessary network resources and activate the service. 

If a customer reports an issue, the customer service representative can access relevant information from both BSS and OSS,  real-time data from OSS can inform BSS about network performance issues that may affect billing or service quality, enabling proactive customer communication and issue resolution.
OSS provides performance and network statuses to BSS, which are used for decision making, billing and customer service.

Therefore, BSS and OSS play complementary roles to each other and work in Synergy to provide high quality services to customers and maximize revenue.


OSS  and BSS play an important role in a telecom network and act as the foundational pillars of telecom operations, with OSS focusing on the technical operations  and maintenance of the network infrastructure, while BSS centers on managing the customer interactions  and the business processes.
Understanding the differences and the importance of their integration helps telecom companies provide high quality services and maintain operational efficiency.
