Understanding OSS and BSS Systems

What do OSS (Operational Support Systems), and BSS (Business Support Systems) stand for? What are their features and characteristics? Where do OSS/BSS intersect or overlap?

It’s very important to state that the combination of OSS and BSS systems allows communication networks to effectively and efficiently provide services to subscribers.

What are Operational Support Systems (OSS) and Business Support Systems (BSS) in Telecom?

The telecommunication industry is a sector made up of companies that provide communication (internet, cell connection, etc.) globally through ordinary or fiber-optic cables, or wireless means. Telecom offers the infrastructure that enables data such as text, voice, and audio/video to be sent worldwide. It’s a crucial feature for modern business operations as network IT solutions are the key to their growth. Reliable network infrastructure is a must for big data applications which are commonly used by companies for business analysis nowadays.

But what about OSS (Operations Support System) and BSS (Business Support System)?

OSS and BSS are the two main functions of the telecom industry. These functions are designed to increase customer service quality, decrease operating costs, and improve network reliability.

What is OSS?

An Operations Support System (OSS) is used by the Communications Service Providers (CSP) to manage their networks. An OSS system supports several functions that are required to manage a telecommunication network such as:

  • service provisioning and activation
  • network inventory
  • fault management
  • network configuration.

CSPs typically collaborate with OSS vendors to customize their OSS systems depending on their network structure and service portfolios. According to the TM Forum Business Process Framework for Telecommunications Operators, an OSS system offers Fulfillment, Assurance, and Billing of services.

An OSS system is usually accompanied by a Business Support System (BSS), which acts as the customer-facing software and accepts service-related requests from the customers or the operator. The requests are forwarded to the OSS system for the actions on the network. It must be noted that not all requests to OSS systems involve network configuration.

OSS is responsible for

Thanks to OSS mobile operators can remotely manage and monitor day-to-day operations, maintenance issues, and activities across the entire network, all from one central location. The system records and captures all network information and presents the data in an easy-to-read format. Therefore, OSS development and integration is a critical network architecture component.

What is BSS?

BSS is a kind of software developed to help telecom organizations manage and streamline all customer-facing activities. BSS covers the whole telecom business, from ordering services to resolving billing issues to upgrading subscriptions.

How do you protect OSS / BSS data from data breaches?

How do you secure the telecom network?

A comprehensive data security management and strategy process plays a vital role in an organization’s efforts to mitigate the risks associated with human errors and insider threats, both of which remain the primary causes of data breaches.

Why do OSS/BSS Require Ongoing Quality Assurance?

OSS and BSS help companies streamline daily activities, improve operational efficiency, and mitigate business risks. Through OSS, telecom providers oversee diverse operations with networks such as planning, configuration, service delivery, and fault management. BSS is responsible for the interaction between telecom companies and their end users. This stack includes billing, subscriptions, CRM, and more.

However, why do these systems require thorough screening? Let’s look into this in detail. There are several reasons:

  1. The activities performed within their work are related to the processing of sensitive and personal data of end users, and often such databases possess millions of records. When migrating to a new billing solution, for instance, these extensive quantities of data must be transferred in full and without affecting the routine actions of subscribers.
  2. When undergoing a digital transformation and following industry trends such as deploying edge computing for increased bandwidth and low latency or switching to 5G for accelerated connection speed, chances are high that their overall complexity will place a burden on telecom providers.
  3. Need-driven quality assurance makes the process of attaining business goals less complicated — 93% of service providers stated that it positively affects customer satisfaction and decreases the outflow of their subscriber base.

Therefore, QA and software testing eases the process of modernizing digital solutions, ensures boosted cybersecurity and performance, and allows for wise allocation of budgets as QA consulting and analysis help to define the pool of necessary verifications accurately.
