High Implementation and Integration Costs
5G infrastructure spending is set to exceed USD 1.3 trillion by 2030, while individual base stations cost USD 100,000–200,000 and core upgrades add USD 20,000–50,000 per site PatentPC. These obligations prompt vendor partnerships, network-sharing alliances, and mergers—such as Nokia’s USD 2.3 billion Infinera acquisition—to spread financial risk Fierce Network. Smaller operators may resort to core-as-a-service models hosted by hyperscalers to contain CAPEX spikes.
Legacy Interoperability Complexity
Multi-generation coexistence means operators must preserve 2G/3G signaling, 4G interworking, and 5G service-based interfaces simultaneously GSMA. Three UK’s replacement of Nokia and Microsoft gear with Ericsson’s unified platform shows the drive to simplify vendor stacks LightReading. Harmonizing lawful intercept, billing, and customer-care processes across divergent network technologies extends timelines and raises integration bills.
Segment Analysis
By IMS Core: SBC Leadership in Voice Evolution
The segment generated the largest revenue slice as Session Border Controllers claimed 38.76% of the mobile core network market share in 2025. SBCs underpin secure IP voice and mediate signaling as operators retire circuit switching. Cloud-native SBC sub-systems will grow at 9.05% CAGR by 2031, propelled by voice-over-5G and enterprise UCaaS overlays. These dynamics elevate the mobile core network market size for SBC providers that marry encryption, analytics, and slice-aware session control. Operators in markets planning 2G/3G sunsets accelerate IMS investments to maintain ubiquitous voice roaming, supporting demand visibility through 2031.
A second wave of modernization targets Voice Application Servers and CSCF nodes. Although smaller in absolute revenue, these functions enable differentiated calling features, integration with collaboration platforms, and service exposure via APIs. The mobile core network market, therefore, opens incremental value pools for software-only vendors that can deliver feature velocity and automation.

By 4G/5G Packet Core Controller: SMF Momentum
The Mobility Management Entity retained the largest installed base, accounting for 30.15% of the mobile core network market size in 2025. Yet its growth plateaus as operators converge on 5G Stand-Alone designs. The Session Management Function, by contrast, surges at 10.45% CAGR, emerging as the logical service anchor for PDU sessions and edge breakout. As SMF deployments rise, adjacent User Plane Function spending follows, creating a multiplier effect inside the broader mobile core network market.
Operators negotiate the coexistence of legacy SGW-C/PGW-C controllers with emerging AMF and SMF stacks. Smooth migration paths, API gateways, and common policy engines are key buying criteria. Vendors able to bundle control-plane, user-plane, and analytics layers within cloud-native constructs gain share as telcos seek integrated, slice-ready platforms.
By 4G/5G Subscriber Data Management: UDM Upswing
Home Subscriber Server dominated in 2025 with a 58.05% share of the mobile core network market size. However, operators recognize the limitations of siloed HSS and increasingly adopt Unified Data Management. UDM’s 12.17% forecast CAGR reflects its ability to present a single subscriber view irrespective of radio technology, enabling micro-segmented policies and slice-specific entitlements. As UDM adoption widens, the mobile core network market sees a pivot from static provisioning toward real-time, context-aware orchestration.
Migration involves schema conversions, latency-sensitive database clustering, and northbound exposure of data via APIs to adjacent IT systems. Vendors offering low-disruption overlays win early projects. Cyber-resilience features are also decisive, given the criticality of subscriber data repositories for identity and billing.
Note: Segment shares of all individual segments available upon report purchase
By Deployment Model: CNF Adoption Curve
Virtualized Network Functions commanded 59.05% of revenue in 2025, reflecting a decade of NFV roll-outs. Converged orchestration and shared x86 hardware drove the first cost-down wave, but operators seek deeper automation and cloud agility. Cloud-Native Functions expand at 7.98% CAGR as telcos containerise control and user planes for microservice scaling. The shift enlarges the mobile core network market as software support, Dev-Sec-Ops tooling, and managed services accompany CNF adoption.
Nevertheless, VNF-to-CNF migration is more than a technical rewrite. Telcos retrain operations teams, rediscover CI/CD pipelines, and redefine vendor contracts for consumption-based pricing. Those unable to operationalize new workflows risk extending the life of VNFs, tempering short-term displacement revenue.
Geography Analysis
Asia-Pacific contributed 39.48% of 2025 revenue, making it the largest regional slice of the mobile core network market, LightReading. China alone invested USD 3 billion in 5G-Advanced cores in 2025 and activated 5.8 million 5G-A users across 300 cities. India’s 687 MHz spectrum reform worth USD 23.16 billion presses operators to accelerate core upgrades. Regional GDP uplift from mobile technologies reached USD 880 billion in 2023, reinforcing political commitment to telecom expansion GSMA. Combined, these factors anchor a robust addressable base for vendors throughout the forecast.
The Middle East represents the fastest-growing theatre at a 13.86% CAGR to 2031. Oil-funded infrastructure programs and sovereign digital agendas collectively escalate spending on cloud-native cores, security overlays, and AI-driven automation.
North America and Europe show mature saturation, yet modernization cycles sustain investment in the mobile core network market. Ericsson’s 54% North American revenue jump in Q4 2024 signals renewed operator spending triggered by spectrum auctions Ericsson. European telcos prioritise Open RAN and energy-efficiency, pairing them with AI-infused core upgrades for private 5G enterprise propositions. Monetisation shifts from new radio footprints to premium API access, edge compute, and intent-based network functions.
Competitive Landscape
Market Concentration
Market concentration is high. Huawei, ZTE, Ericsson, and Nokia captured roughly 70% of 2024 revenue in the mobile core network market TelecomLead. Huawei’s 22% revenue rise to USD 118 billion in 2024 contrasted with Ericsson’s 5% dip and Nokia’s 21% Q4 2023 fall LightReading. Geopolitical restrictions reshape addressable territories: Huawei dominates in APAC and Middle East, while Ericsson fortifies ties in Europe and North America. Operator preference for fewer suppliers drives replacement deals such as Three UK’s migration to Ericsson’s unified core LightReading.
Technology leadership hinges on AI integration and cloud-native feature sets. Huawei premiered an AI-native core at MWC 2025, TotalTelecom released an autonomous network white paper, and Ericsson partnered with Google Cloud for core-as-a-service. Hyperscalers push deeper: Microsoft’s Azure Operator 5G Core and AWS Outposts threaten traditional vendor margins by bundling cloud credits with telco platforms. In response, legacy vendors broaden software portfolios, acquire optical players to control transport layers, and promote DevOps-centric engagement models.
