Core networks
Resilient mobile core solutions designed for autonomy
Building core networks for the AI era
The mobile core is becoming the intelligence layer of the network. As you evolve your network to 5G-Advanced and prepare for 6G, you need a core that does more. It must strengthen security, support service innovation, simplify operations and help turn network performance into business value.
Our mobile core is designed for the AI era. It evolves from cloud-native to AI-native, further enhancing our mobile core’s autonomy, resilience and agility with large language models, machine learning, agentic AI and a 5G User Plane Function for inferencing at the network’s edge. By embedding automation, analytics and AI into core network functions, we enable deeper visibility, faster decision-making and more efficient lifecycle management bridging private, public and hybrid cloud environments.
AI-native core for the journey to 6G
AI is becoming intrinsic to the mobile core, enabling predictive operations, anomaly detection, self-healing and intent-driven autonomous operations that support the evolution to 5G-Advanced and 6G.
Built for resilience and security
Advanced threat detection, inline mitigation and AI-assisted insights help protect the mobile core from cyber threats and operational disruption while supporting reliable, continuous service delivery.
Cloud-native scale across multi-cloud environments
Cloud-native network functions and flexible multi-cloud deployments help telecommunication providers scale efficiently, accelerate updates and introduce new services faster across evolving network environments.
One converged core serving multiple mobile generations and cloud platforms
Our core network solutions provide a cloud-native architecture bridging 2G, 3G, 4G and 5G, as well as fixed access and IMS voice. This offers telecommunication providers a consistent foundation for modernizing the mobile core without adding complexity across network generations, domains or deployment models.
With support for private, public and hybrid cloud environments, you can deploy the core on the platform that best fits your business, regulatory and operational needs. The result is a more unified, secure and efficient core that is easier to evolve, manage and scale.

Frequently asked questions
The mobile core controls the mobile network. It manages subscriber authentication, mobility, policy and charging as well as the routing of voice and data traffic. It connects users and devices to services across radio, transport and IT domains, helping ensure the right performance, security and experience. As networks evolve to 5G standalone, the core becomes more service-based, programmable and analytics-driven, enabling new consumer and enterprise services.
Telecommunication providers can deploy the mobile core in several ways, including private cloud environments in their own data centers, edge locations and regional facilities. Some are adopting hybrid models that combine on-premises infrastructure with public cloud resources to balance control, latency, compliance and cost. Some are also turning to SaaS models, where the vendor delivers core software lifecycle management and operations as a subscribed service while the telecommunication provider retains ownership of customer relationships and services.
In 5G standalone, voice is delivered using Voice over New Radio (VoNR), which runs natively over the 5G core and 5G radio, using an IP Multimedia Subsystem (IMS) core for session control. Telecommunication providers operate VoNR alongside VoLTE (4G voice) to maintain service continuity where 5G voice is still evolving. This allows the introduction of new voice experiences, such as IMS Data Channel (also known as New Calling) with a cloud native core.
A cloud-native mobile core disaggregates network functions into microservices that can be deployed, scaled and updated independently. This improves agility, resilience and operational efficiency, helping telecommunication providers introduce new services faster and with less risk. It also provides the foundation for multi-cloud deployment, lifecycle automation and large-scale exposure of network capabilities through APIs.
Core SaaS can help telecommunication providers accelerate deployment and reduce operational complexity by shifting much of the design, integration and lifecycle management to the vendor. Managing the core directly offers greater control over architecture, customization and tooling, but typically requires deeper cloud and DevOps expertise. Key considerations include available skills, regulatory requirements, speed to market, cost model and the strategic importance of owning the core platform.
AI is changing the mobile core in two ways. First, AI can be embedded into the core and its operations to improve automation, assurance, security and efficiency. Second, the 5G core can provide the high-performance, deterministic connectivity needed to support AI applications across cloud, edge and enterprise environments. Together, these roles help telecommunication providers run more autonomous networks while opening new services and monetization opportunities.
