Communications service providers (CSPs) find themselves in an interesting position, facing an unprecedented opportunity to transform their approach to building and operating network infrastructure. Yet most CSPs remain reluctant to act, as undergoing such a transformation requires many changes within the functioning of telecommunications systems, such as implementing cloud technologies<\/a> and enabling agility, decentralized governance, security, scalability, and continuous delivery.<\/p>\n

Why is BSS\/OSS system architecture transformation critical?<\/h2>\n

More and more telecom subscribers tend to expect cutting-edge automated service delivery and support from their operators. Moreover, the rapid growth of telecom services has increased the complexity of network operations and management. Keeping up with the telecom market competition has become impossible without a proper operations support system (OSS) and business support system (BSS).<\/p>\n

One of the most significant shortcomings of existing telecom mainframes is their rigidity. Telecom software development<\/a> is painstakingly slow, as vendors have to ensure integration and interoperability of their systems with all components available on the market \u2014 or with most of them, at the very least.<\/p>\n

Telecom providers are used to overhauling their OSS\/BSS system design<\/a> every few years or so when newer equipment becomes available \u2014 yet this costs quite a lot. As shown above, the shift towards 5G that started in 2018 is pressing telecom operators to revamp their IT infrastructure once more to support up to the 300 GHz bandwidth. But this is hard to do through hardware alone.<\/p>\n

Legacy systems consist of multiple hardware and software components that are hard to reconfigure. Any update, upgrade, or adjustment entails significant expenses and leads to a high total cost of ownership.<\/p>\n

Also, scaling legacy systems is complicated, as adding more capacity does not remove structural and operational bottlenecks. For example, it doesn\u2019t matter that your network has 15 switches with 1 Gbps bandwidth each if they\u2019re all connected to a 1 Gbps router that physically cannot provide 15 individual 1 Gbps channels. Therefore, installing 15 100 Mbps switches with 70 Mbps max throughput would be a way better option. 5G networks<\/a> face the same problem, just magnified.<\/p>\n

The progress of 5G service rollouts and the constant increase in IoT device deployments<\/a> consequently create greater demand for business agility. Legacy BSS\/OSS architecture in telecom can no longer cover all the market needs or fulfill the necessary security requirements. According to Allied Market Research<\/a>, the global BSS\/OSS market was valued at $36.85 billion in 2019, and it is projected to reach $102.14 billion by 2027.<\/p>\n

Still, communications service providers are striving to modernize. The emerging OSS\/BSS architecture in the telecom sector will help unify the complex system of OSS operations using integral IT paradigms such as network function virtualization (NFV), E2E service orchestration, big data analytics<\/a>, and software-defined networking (SDN).<\/p>\n
