Operational Support System (OSS) Modernization Market Report 2026

The operational support system (oss) modernization market size has grown rapidly in recent years. It will grow from $16.34 billion in 2025 to $18.66 billion in 2026 at a compound annual growth rate (CAGR) of 14.2%. The growth in the historic period can be attributed to legacy oss fragmentation in telecom, migration to virtualized network functions, growth of service assurance requirements, pressure to reduce opex in network operations, expansion of multi-vendor network environments.

The operational support system (oss) modernization market size is expected to see rapid growth in the next few years. It will grow to $31.42 billion in 2030 at a compound annual growth rate (CAGR) of 13.9%. The growth in the forecast period can be attributed to support for 5g and network slicing operations, intent-based orchestration adoption, genAI copilots for oss operations teams, real-time closed-loop automation, standardization around open digital architectures. Major trends in the forecast period include cloud-native oss transformation programs, aiops for network fault and performance management, api-first oss integration with partner ecosystems, automation of service assurance workflows, unified inventory and resource orchestration.

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.

Major companies operating in the operational support system (oss) modernization market are Huawei Technologies Co. Ltd, Accenture plc, International Business Machines Corporation, Cisco Systems Inc., Oracle Corporation, Hewlett Packard Enterprise Company, Tata Consultancy Services (TCS) Limited, Capgemini SE, Telefonaktiebolaget LM Ericsson, NEC Corporation, Nokia Corporation, Cognizant Technology Solutions Corporation, Infosys Limited, ZTE Corporation, HCL Technologies Limited, Wipro Limited, Tech Mahindra Limited, Amdocs Limited, Ciena Corporation, Comarch SA.

North America was the largest region in the operational support system (OSS) modernization market in 2025. Asia-Pacific is expected to be the fastest-growing region in the forecast period. The regions covered in the operational support system (oss) modernization market report are Asia-Pacific, South East Asia, Western Europe, Eastern Europe, North America, South America, Middle East, Africa. The countries covered in the operational support system (oss) modernization market report are Australia, Brazil, China, France, Germany, India, Indonesia, Japan, Taiwan, Russia, South Korea, UK, USA, Canada, Italy, Spain.

Tariffs have created both challenges and opportunities for the OSS modernization market by increasing the cost of importing telecom servers, storage systems, and networking hardware required for upgrading legacy operational platforms. These cost increases can slow modernization and capacity expansion for communication service providers, particularly in North America and Europe that rely on Asia-Pacific supply chains for critical infrastructure components. Hardware-heavy segments such as on-premises OSS deployments, performance monitoring appliances, and private cloud infrastructure are most affected due to longer lead times and higher capital costs. However, tariffs are accelerating cloud migration, encouraging regional sourcing, and driving vendors to enhance automation and modular architectures that reduce reliance on hardware-heavy upgrades while improving agility.
