Key trends in the forecast period include technological advancements in artificial intelligence-driven network automation, advancements in cloud-native architecture for operations systems, innovations in data orchestration and analytics for service management, developments in low-code and no-code platforms for operational workflows, research and development in predictive maintenance and fault management solutions, and advancements in API-based integration frameworks for real-time network visibility.

The expansion of 5G deployments is expected to propel the growth of the operational support system (OSS) modernization market going forward. 5G refers to the fifth generation of mobile network technology that delivers faster data speeds, lower latency, and higher connection density than previous network generations. 5G adoption is rising due to the growing demand for faster and more reliable connectivity to support data-intensive applications and real-time digital services. OSS modernization facilitates 5G expansion by enabling automated, scalable, and real-time management of complex, cloud-based network operations. For instance, in June 2025, according to 5G Americas, a US-based wireless industry trade association representing operators and manufacturers in the Americas, global 5G connections reached 2.4 billion in the first quarter of 2025 and are projected to reach 8 billion by 2029. Therefore, the expansion of 5G deployments is driving the growth of the OSS modernization market.

Key companies operating in the OSS modernization market are focusing on incorporating innovations such as generative artificial intelligence (AI) to enhance service agility, automation, and operational efficiency. Generative AI (GenAI) is an advanced form of artificial intelligence that uses large language models and deep learning techniques to create new content, such as text, code, or configurations based on natural language prompts, enabling capabilities such as automated service design, intelligent configuration generation, and rapid product deployment. For instance, in November 2023, Cerillion, a UK-based telecommunications software provider, launched Cerillion 23.2, a GenAI-powered business support system (BSS) and OSS suite designed to simplify product catalog management, accelerate offer creation, and reduce time-to-market for telecom operators. The platform features natural-language-driven product configuration, AI-assisted offer design, and seamless integration with Microsoft Office 365 for cross-platform access. Cerillion 23.2 improves business agility, reduces manual configuration errors, and empowers non-technical teams to innovate faster, supporting the broader modernization of OSS environments.

In July 2025, Virtusa Corporation, a US-based digital engineering and information technology (IT) services provider, acquired Sincera Technologies for an undisclosed amount. With this acquisition, Virtusa strengthens its capabilities in data engineering, BSS and OSS modernization, and AI-driven digital transformation for telecom operators. Sincera Technologies, a US-based provider of cloud and data solutions for the telecommunications industry, is known for its expertise in modernizing legacy BSS/OSS systems and enabling cloud-native network transformations.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid escalation of U.S. tariffs and the resulting trade tensions in spring 2025 are significantly impacting the information technology sector, particularly in hardware manufacturing, data infrastructure, and software deployment. Higher duties on imported semiconductors, circuit boards, and networking equipment have raised production and operational costs for tech firms, cloud service providers, and data centers. Companies relying on globally sourced components for laptops, servers, and consumer electronics are facing longer lead times and increased pricing pressures. In parallel, tariffs on specialized software tools and retaliatory measures from key international markets have disrupted global IT supply chains and reduced overseas demand for U.S.-developed technologies. To navigate these challenges, the sector is accelerating investments in domestic chip fabrication, diversifying supplier bases, and adopting AI-driven automation to enhance operational resilience and cost efficiency.
