Transform your operations and service portfolio

5G SA delivers an entirely new level of agility for services and their management, driving efficiencies and new opportunities.

Proven technology

Our solutions are proven in deployments globally, both individually and as a complete core – so you can migrate from legacy solutions or start from scratch with greenfield operations and grow with demand.

Benefit from the power of full 5G

5G Standalone provides an entirely new core network, optimised for the new generation of differentiated services – including Voice over New Radio (VoNR), data, and messaging. Migrate from 5G NSA or build out a greenfield network with WTL’s complete range of solutions – a complete core, supporting advanced data processing and efficient operations.

High-speed packet routing

The User Plane Function manages all data routing, providing the link between user devices and external data networks, across different slices.

Control and User Plane Separation

With CUPS, the UPF ensures that user plane data is routed correctly and enables low-latency capabilities for URLLC services. With Edge UPF deployments, you can deliver optimised data management for key services and partners.

Scalable service evolution

WTL’s UPF enables you to efficiently process data, with capacity for 20 Gbps for each instance – so you can build out a complete data fabric as your traffic and service demand grows. Deploy in the core or distribute to the edge, so you can support any kind of 5G service and slice with optimised performance.

Session Management Function

The SMF controls user data sessions from devices in the RAN. It determines which UPF is selected for data handling and provides routing instructions.

Dynamic session control

Fully compliant to 3GPP standards and the SBA, WTL’s SMF is central to the control plane, delivering the session management you need to deliver advanced services and to manage mobility effectively in your network.

Policy management, analytics and more 

The SMF is essential for setting and enforcing policies, with QoS management and application-level granularity – enabling more effective service differentiation and monetisation. The visibility into each session provides analytics and insights for proactive service assurance, supporting operations to meet your SLAs and customer expectations.

Access and Mobility Management Function

The AMF is the heart of mobility management in the 5GC, handling access across multiple carriers and enabling network slicing.

Device registration and authentication

All non-access stratum (NAS) control information is managed through the AMF, with UE connectivity monitored to ensure services can be accessed when required. The AMF ensures control plane data is routed to the appropriate NF, according to policies and slice requests.

Crucial for slice management

By enabling connectivity to specific slices, the AMF is central to differentiated, QoS-dependent services, enabling you to offer valuable performance guarantees, backed by the security you need to meet governance procedures. WTL’s AMF supports all necessary functional and resilience requirements, providing a complete solution.

Policy Control Function

A significant evolution from the PCRF and reinforcing separation of enforcement from policy decisions, the PCF is key to differentiated services and QoE.

Build out enhanced services

Different policies and rules can be applied per service, which means a UE can easily access the resources required by a given application. With the PCF, you can design and launch truly differentiated services, at scale, to enable effective monetisation of your investments.

Performance to match your ambitions

Offering high processing capabilities, WTL’s PCF offers you the scale you need to expand and enrich your service portfolio. Fully leverage the capabilities of 5G by targeting low latency applications, vertical and industrial sectors – or enable new partnerships with specialised requirements. WTL’s solution allows you to build compelling propositions.

Network Repository Function

All 5GC Network Functions and their capabilities must be registered in the NRF to enable them to be accessed to support each active service. 

Enabling dynamic configuration and scale

Capacity and capability management are integral to the 5GC. The NRF supports load balancing and capacity management, in real-time, while also enabling service conditions to be managed during sessions when different slices are required, and protecting security.

Accelerates service launch

The NRF gives you complete control over the performance and security of your 5GC and the deployed NFs, so it’s fundamental to managing a diverse and differentiated service portfolio. Instantly register new NFs and integrate them into your core, allowing dedicated resources to be allocated and new propositions dynamically configured.

Authentication Server Function for AKMA

The AUSF plays a key role in securing the 5GC and supports the complete AKMA workflow for persistent UE authentication and service access.

Enhanced security for UE admission

3GPP specified new protocols for authenticating UEs and the services they can access on first registration with the mobile network – extending existing 4G methods to deliver enhanced protection. Subscription identifiers are encrypted and keys are created for each session.

3GPP and non-3GPP access control

WTL’s AUSF fully complies with the enhanced 3GPP procedures, providing authentication for both 3GPP and non-3GPP access. Because further keys can be derived from the root session key or KUASF, UEs can easily be admitted to different applications – and different AFs can use this central authentication service, without the cost of further validation.

Network Slice Selection Function

Network slices are a foundational innovation unlocked by 5G SA – to capitalise on differentiated and premium offers, you need flexible, dynamic slice control.

Agile slice delivery

With WTL’s NSSF, slices can be allocated to user sessions based on both policies and requests from applications and devices – delivering the performance to meet specific demands, contexts and situations, and enabling mobility between slices.

Performance for demanding services

Like all WTL’s 5G core NFs, the NSSF is built to meet the cloud-native performance and resilience demands of services that can be delivered to different verticals, consumers and businesses, fully aligned with 3GPP standards and security considerations. It’s key to providing a robust portfolio of differentiated 5G services.

Unified Data Management

The UDM function replaces the HSS from the HSS in 4G and provides a new way of managing user profiles and subscriptions, working in tandem with the UDR. 

Comprehensive user and device security

5G brings enhanced security to protect user and UE identities for which the UDM is a key element. It interacts with the AUSF to ensure identities are hidden and encrypted, while also protecting the network from unauthorised users and devices. 

Centralised subscription data

Brining all subscription information together and making it accessible to other NFs in the 5GC, the UDM enables you to control network access and determine the capabilities granted to different users and devices, based on their profiles. It also consolidates in- and outbound roaming service data, supporting your roaming business.
