IP Multimedia Subsystem Market to Reach USD 9.05 Billion by 2032 as 5G, Cloud-Native Networks and VoNR Accelerate Adoption

Market Estimation, Growth Drivers and Opportunities

The global IP Multimedia Subsystem (IMS) Market was valued at USD 3.83 billion in 2025 and is projected to reach USD 9.05 billion by 2032, expanding at a CAGR of 13.07% during 2026–2032. IMS provides a standardized architecture for delivering voice, video, messaging and other multimedia communications across fixed and wireless networks. The transition from legacy networks toward LTE and 5G is a major growth catalyst, as IMS provides the underlying architecture for services such as Voice over LTE (VoLTE), Voice over Wi-Fi (VoWiFi), Voice over New Radio (VoNR) and Rich Communication Services (RCS). Increasing smartphone penetration, rising demand for high-quality communication services and the need for telecom operators to reduce network operating costs are strengthening adoption. The expansion of 5G infrastructure represents a particularly important opportunity because IMS is the standardized voice platform for 5G standalone networks. Telecom operators are also moving toward cloud-native, virtualized and software-defined architectures, creating opportunities for flexible IMS deployments, network automation and new communication-based revenue streams.

U.S. Market Trends and Investment

The United States is at the forefront of IMS adoption as operators modernize networks for 5G and increasingly migrate voice infrastructure toward cloud-native architectures. A significant 2025 development was Boost Mobile's deployment of Nokia's fully cloud-native 5G Voice Core on public cloud, consolidating multiple IMS voice 3GPP functions into a single cloud-native network function. Nokia reported that the deployment was designed to accelerate new 5G services, improve network automation and reduce infrastructure and operating costs, with Boost expecting significant network infrastructure savings. In February 2025, AT&T also expanded its multi-year relationship with Nokia to deploy Nokia 5G IMS Voice Core and Digital Operations software, supporting automation and faster service deployment. These developments coincide with U.S. government efforts to expand advanced wireless capabilities. The National Telecommunications and Information Administration's National Spectrum Strategy is designed to increase access to advanced wireless broadband and promote U.S. leadership in wireless technologies, while its implementation activities continue to examine additional spectrum resources for next-generation connectivity.

Market Segmentation: Largest-Share Segments

Based on operator, the mobile operators segment is expected to register the largest CAGR of 14.87% during the forecast period. Mobile operators are investing heavily in next-generation infrastructure to replace or upgrade legacy technologies and satisfy rising consumer demand for high-quality voice, video and data services. The transition toward 5G and the increasing penetration of smartphones are encouraging operators to deploy IMS-based solutions capable of supporting next-generation communication services.

By component, the product segment is expected to grow at the largest CAGR of nearly 15% during the forecast period. Telecom operators are deploying IMS solutions at scale to support applications including VoLTE, VoWiFi, UCaaS and RCS. The increasing requirement for reliable IP-based communications and standardized service delivery is therefore supporting demand for IMS products.

Competitive Analysis

The MMR report identifies Oracle, Huawei, Ericsson, NEC and Nokia among the key companies covered in the global IMS market. Because the report does not provide individual percentage shares for these companies on the public page, they are presented here as leading/key market participants rather than assigning unsupported market-share rankings.

Oracle is strengthening its communications portfolio around cloud-native 5G core, signaling, routing, automation and analytics. Its 5G Core architecture supports automation, real-time analytics, policy control and multicloud deployment, helping telecom operators modernize infrastructure and introduce new services. In 2025, Transatel selected Oracle's cloud-native 5G signaling core for next-generation connectivity across automotive and industrial applications, highlighting the broader opportunity for programmable communications infrastructure.

Huawei remains a major telecom infrastructure supplier, with IMS positioned within the broader transition toward 5G and cloud-based network architectures. Its focus on intelligent network management, automation and advanced 5G infrastructure supports the industry's movement toward more flexible communications platforms.

Ericsson continues to develop IMS and 5G Voice technologies to support VoLTE and VoNR. Its 5G Voice solutions are designed to provide high-quality voice and video services while enabling operators to introduce new communication services for consumers and enterprises. In April 2025, Ericsson announced a EUR 200 million investment over three years in research, development and innovation at its Athlone facility in Ireland, targeting programmable networks and automation capabilities used in 5G networks globally.

NEC is participating in the evolution toward open, software-defined and cloud-native telecommunications infrastructure. Its focus on virtualization, open networking and 5G-related technologies creates opportunities for IMS modernization as operators move away from proprietary legacy systems.

Nokia made significant progress in cloud-native IMS during 2025. Boost Mobile's U.S. deployment of Nokia's cloud-native 5G Voice Core demonstrated the migration of IMS functions to public cloud infrastructure. Nokia also signed a multi-year agreement with AT&T in February 2025 covering its 5G IMS Voice Core and Digital Operations software. In July 2025, Optus selected Nokia's Cloud Native Communication Suite to refresh its IMS voice platform and support highly resilient 5G voice services through a hybrid-cloud architecture.

Regional Analysis

USA: North America accounted for the largest 32% share of the global IMS market in 2025, supported by smartphone adoption, telecom modernization and initiatives encouraging advanced wireless infrastructure. The region's focus on 5G deployment and spectrum modernization is creating favorable conditions for IMS investment.

UK: The UK market benefits from continued 5G deployment and increasing adoption of cloud-based telecom infrastructure. The migration of operators toward virtualized and automated networks is creating opportunities for IMS providers, particularly in 5G voice and converged communication services.
