Asia-Pacific 5G Core Network Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

Asia-Pacific 5G Core Network Market Trends and Insights

Accelerated 5G Standalone Core Migration

Operators across the Asia-Pacific 5G core network market are moving away from non-standalone architecture because advanced 5G services require a standalone core. Network slicing, private networks, and low-latency APIs cannot offer their intended capabilities through a 4G Evolved Packet Core. This requirement turns migration into a broad software, infrastructure, and integration program, involving new packet-core functions, lifecycle tools, data migration, testing, security validation, and operational preparation before commercial traffic can be moved. NTT DOCOMO and NEC launched Japan's first commercial 5G core on AWS in February 2026. The companies said AI-based construction cut deployment time by 80%, and AWS Graviton2 processors reduced power consumption by 70%.^{[1]NTT DOCOMO, “DOCOMO and NEC Launch Japan's First Commercial 5G Core on AWS, Built With World's First AI-Automated Network Construction Technology,” NTT DOCOMO, docomo.ne.jp} Reliance Jio's standalone core supported 130 million users and carried 33% of its total data traffic in 2025, showing the scale available once a migration is complete.

Cloud-Native Core Modernization in Tier-1 Operator Networks

Cloud-native modernization has become central to how large operators in the Asia-Pacific 5G core network market plan future network operations. Containerized functions and automated orchestration can reduce the time required to deploy and update network services. Ericsson signed a multiyear agreement with SoftBank in March 2026 to modernize nationwide core functions with a cloud-native dual-mode 5G Core. The program covers access and mobility management, mobility management entity functions, voice gateways, and policy control.^{[2]Ericsson, “Ericsson to Expand and Modernize SoftBank Corp.'s Core Network in Japan,” Ericsson, ericsson.com} Tune Talk completed the first phase of its cloud-native core modernization with Nokia in January 2026, becoming the first Southeast Asian telecommunications operator to deploy the architecture at scale. These deployments place public cloud providers more firmly within the core network supply chain, while leaving operators responsible for selecting which functions can run centrally and which require local processing for latency, resilience, or data control.

Network Slicing Demand from Manufacturing and Industrial IoT

Manufacturing and logistics facilities are creating a clear commercial case for network slicing in the Asia-Pacific 5G core network market. These sites need predictable connectivity for automated guided vehicles, production control, machine vision, and maintenance systems. Telkomsel and Pegatron deployed a standalone 5G private network at a factory in Batam with sub-10-millisecond latency and network slicing. The deployment supported production reconfiguration that was more than 70% faster, a 5% improvement in overall equipment effectiveness, and 99.9% uptime for automated guided vehicles.^{[3]GSMA, “APAC 5G Industry Case Study Report 2025,” GSMA, gsma.com} Bharti Airtel launched commercial 5G network slicing in India with Ericsson technology in 2025. Dedicated service levels allow operators to charge enterprises for assured network performance rather than only for data volume, thereby linking service pricing to measurable operational requirements such as response time, reliability, traffic priority, and consistent coverage within a facility.

Private Networks and Enterprise API Monetization

Private networks and standardized network APIs are expanding the revenue options available to core network operators. A standalone core can expose controlled features, including location, session control, and quality of service, to approved third-party applications. The GSMA reported that its CAMARA initiative had commitments from 47 operator groups representing 239 networks and 65% of global connections. This common interface gives developers a more consistent way to use network capabilities across operators. Reliance Jio launched 10 active 5G network slices nationwide in August 2025 for IoT, gaming, fixed wireless access, and mission-critical uses. The Network Exposure Function is consequently becoming more important because it provides the controlled gateway for these API services, allowing an operator to apply permissions, service rules, and quality controls before network capabilities are made available to enterprise users and developers.

High Upfront Integration Cost and Long Payback Cycles

Full standalone core programs require spending on software licenses, cloud infrastructure, orchestration tools, and multiyear integration services. This burden is particularly difficult for smaller operators in Southeast Asia, Pacific markets, and South Asia. Lower average revenue per user limits their ability to absorb the cost within normal investment cycles. Integration work for testing, multi-vendor orchestration, and live traffic migration can account for 30-40% of the project cost. These expenses can emerge late in the project and postpone the launch of enterprise services. Managed service and core-as-a-service models can reduce this pressure by spreading implementation and operating costs over a longer period, but availability outside Japan and Australia remains limited for operators that need local support and proven delivery partners.

Legacy EPC Coexistence Delays and Migration Complexity

Operators often need to run a 4G Evolved Packet Core and a standalone 5G core in parallel during migration. This arrangement duplicates infrastructure costs and creates difficult interworking tasks. It also makes subscriber migration more sensitive, as operators must avoid disrupting existing services. Bharti Airtel has taken a phased approach in India, with fixed wireless access already using standalone 5G while mobile customers move in stages. The longer coexistence period extends payments for legacy maintenance alongside spending on new core equipment. These conditions can delay expected vendor returns and slow growth in the Asia-Pacific 5G core network market in countries with complex legacy estates, especially when operators must maintain old contracts, protect service continuity, and train teams to support two very different core environments simultaneously.

Segment Analysis

By Component: Software Architecture Anchors Long-Term Revenue

Solutions are expected to hold 61.19% of the Asia-Pacific 5G core network market share in 2025. This category includes packet-core software, network functions virtualization infrastructure, and orchestration and management tools. Packet-core software is highly valuable because operators license separate functions that they can upgrade and scale without replacing every hardware layer. Access and mobility management, session management, and user plane functions are examples of these disaggregated functions. Commercial off-the-shelf servers and Kubernetes platforms remain important parts of the infrastructure stack. However, public-cloud contracts are taking on some infrastructure spending that previously went to owned platforms.

Services are projected to expand at a CAGR of 23.44% through 2031 within the Asia-Pacific 5G core network industry. This category covers integration and deployment, consulting and advisory work, and support and maintenance. Integration remains the main service activity for greenfield standalone deployments in India and upgrades in Japan and South Korea. Legacy core coexistence adds testing and traffic cutover work to these projects. Consulting demand is also rising among mid-tier operators that lack deep internal cloud engineering teams. Therefore, the service opportunity in the Asia-Pacific 5G core network market extends beyond the initial buildout, as operators manage and optimize multi-vendor networks, adjust automation policies, and handle regular software releases required in a cloud-native environment.

By Deployment Model: Public Cloud Gains Ground as Operators Pursue Elastic Capacity

On-premises and dedicated architectures are expected to account for 51.69% of the Asia-Pacific 5G core network market size in 2025. Their lead reflects the scale of Chinese Tier-1 operators and the preference for controlled core environments under state-directed infrastructure programs. China Mobile, China Telecom, and China Unicom use standalone core deployments at a national scale. Domestic suppliers Huawei and ZTE have supported these programs. Dedicated installations also suit operators who must keep sensitive data and real-time processing within their own environments. This model remains important where sovereignty requirements are strict or latency guarantees are central to the service.

Public cloud is projected to expand at a CAGR of 26.50% through 2031. NTT DOCOMO's commercial AWS deployment gives regional peers a carrier-scale reference point for cloud-hosted core functions. Tune Talk uses AWS in Malaysia for its control plane while retaining its user plane locally on AWS Outposts at the edge. This arrangement addresses both latency and data residency requirements. Hybrid and telco edge models are also gaining traction in Japan, South Korea, and Australia. These models allow operators to use cloud capacity for less latency-sensitive functions while retaining local processing for enterprise services.

By End User: Operator Scale Underpins Revenue While Enterprises Reshape Growth

Telecom operators are expected to account for 72.25% of end-user revenue in the Asia-Pacific 5G core network market in 2025. National core refresh programs at China Mobile, NTT DOCOMO, Reliance Jio, SK Telecom, and comparable operators are creating the largest purchasing volumes. These companies procure core software, infrastructure, integration, and long-term support at substantial scale. Their role remains central because they operate the public networks that carry most mobile traffic. The Asia-Pacific 5G core network market will continue to rely on these refresh cycles for much of its revenue base. However, operator spending is becoming a smaller share of total demand as dedicated enterprise deployments increase.

Enterprises are projected to expand at a CAGR of 25.88% through 2031. Manufacturing is adopting 5G private networks because they can support measurable improvements in production and maintenance processes. At Pegatron's Batam factory, Telkomsel reported a 20% cost reduction, with 50% of the savings linked to reduced cabling.^{[4]Telkomsel, “Telkomsel Launches 5G for IoT and AI in PT Pegaunihan's Smart Factory,” Telkomsel, telkomsel.com} Energy and utilities, transportation and logistics, public safety, and smart city projects are also building cases for dedicated connectivity. Government procurement in Singapore, South Korean industrial corridors, and Chinese pilot zones can help fund initial deployment costs. This trend broadens the buyer base beyond conventional telecommunications operators and requires vendors to serve organizations with procurement cycles, operating priorities, security expectations, and technical teams that differ from those of the national carriers that historically purchased most core network infrastructure.

By Network Function: UPF Anchors the Data Plane While NEF Drives Monetization

The User Plane Function is expected to hold 20.79% of the Asia-Pacific 5G core network share in 2025. It processes subscriber data traffic, so its deployment value rises with subscriber scale and traffic volume. Mavenir's Converged Packet Core, including User Plane Function capabilities, is expected to go live on Rakuten Mobile's network in April 2026. The platform supports the infrastructure used for Japan's emergency roaming service. Access and Mobility Management Function and Session Management Function deployments follow closely because they govern access, authentication, and session management. Together, these functions provide the operational base for large public 5G networks.

The Network Exposure Function is projected to expand at a CAGR of 27.71% through 2031. It provides the controlled API layer through which third parties can use network capabilities. CAMARA's common specifications make this interface more consistent across participating operators. Authentication Server Function, Unified Data Management, and Network Repository Function remain essential to a complete standalone architecture. Deployments of the Network Slice Selection Function, Policy Control Function, and Application Function are also increasing as operators offer differentiated services. These capabilities help align enterprise service requirements with the underlying core network.

Geography Analysis

China is expected to account for 49.50% of the regional total in 2025. State-directed deployment programs have supported the national scale of China Mobile, China Telecom, and China Unicom. The country is expected to have more than 3.6 million 5G base stations operating across these carriers. This radio footprint requires substantial core capacity and supports continued software procurement. China also favors controlled and sovereign core deployments that align with domestic infrastructure policies. Japan has a smaller geographic footprint but maintains a high concentration of cloud-native core deployments.

India is projected to expand at a 25.00% CAGR through 2031 in the Asia-Pacific 5G core network market. Reliance Jio operates an indigenous cloud-native standalone stack, while Bharti Airtel is using a hybrid rollout with Nokia and Ericsson technologies. These models indicate that the India opportunity includes both locally developed and international vendor approaches. India has also expanded the addressable need for core functions through 5G spectrum planning, including the 6 GHz band. South Korea follows a separate path based on its government-led standalone upgrade requirement. KT operates standalone services commercially, while SK Telecom has targeted a commercial standalone launch during Q4 2026.

Southeast Asia remains fragmented, but early deployments provide practical templates for other operators in the subregion. Tune Talk's cloud-native core program in Malaysia showed that the model can work beyond the largest carriers. ZTE and Telkomsel are also expected to introduce a hybrid private network in Indonesia in 2025 for automotive manufacturing. Australia, New Zealand, and Pacific markets are pursuing cloud-native voice core modernization. This pattern places the Asia-Pacific 5G core network market on a varied path, with large national networks, industrial deployments, and cloud-based voice upgrades advancing together. However, local regulation and operator scale continue to determine the preferred core architecture in each country.
