Which 4G LTE Core Network Components Does WTL Support?
4G LTE solutions
Modernise, extend and enhance your 4G core
WTL’s 4G core solutions are optimised for performance and deliver outstanding value – so you can transform service delivery.
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.
Containerised and cloud native
WTL’s containerised, cloud native architecture reduces hardware requirements and enables rapid deployment – alongside existing investments with minimal operational disruption. Scale resources to match network load for efficient operations and management – without compromising performance, reliability or security. Standardised management interfaces reduce complexity and align with your assurance systems.

4G MVNO
Enhanced authentication and authorisation
Our HSS solution is ideal for replacing legacy platforms or for MVNOs that wish to take control of service access and subscriber data.
Standards compliant for full interop
Supporting all necessary Diameter interfaces, WTL’s HSS slots seamlessly into the core network, with rapid deployment and provisioning, even when migrating an existing data set, so performance is assured from the outset.
Combine HSS and HLR in a single solution
The HSS can be combined with HLR functionality to service legacy networks, reducing operational complexity and overhead. Enhanced security protects against vulnerabilities, assures regulatory compliance, and ensures privacy for your subscribers. Data is protected against unauthorised access and malicious activities and threats, safeguarding your reputation.

HSS
Dynamic policy and charging capabilities
Built for MNOs and MVNOs, WTL’s PCRF solution gives you automated and granular control over your services, enabling new levels of personalisation and charging models.
Automated, real-time policy management
Automatically manage policies based on subscriber behaviour, network conditions and application demands. Ensure consistent service delivery in the context of the live network and usage, dynamically, for optimised resource utilisation and subscriber satisfaction.
Take control with rapid deployment
The PCRF is key to delivering differentiated, QoS-based services. WTL’s PRCF solution can be deployed rapidly and offers the scale and performance you need to boost your service portfolio. MNOs can migrate from legacy solutions and extend their capabilities – or MVNOs can diversify their portfolio and target new opportunities.

PCRF
Combines session management and DPI
WTL’s innovative A-PGW solution unifies Packet Gateway, application visibility and analytics with layered security and an integrated CGNAT in a single, 3GPP-compliant solution.
Reduced latency and TCO
The A-PGW reduces latency with intelligence in the packet forwarding path, eliminating latency introduced when DPI is deployed separately. The solution simplifies network operations and reduces TCO by consolidating functionality into a single platform.
Flow-based DPI
Supporting more than 450 protocols, across consumer and business applications, like gaming, streaming, file sharing, VoIP / UC, collaboration tools, email, VPNs and more, the A-PGW enables policies to be applied with zero latency and backed by multi-layered security that eliminates blind spots — delivering wire-speed, assured performance.

A-PGW
Easily manage Diameter traffic
WTL’s Diameter Routing Agent provides agile capabilities to manage essential Diameter signalling traffic, with intelligent, automated distribution of messages to ensure optimised resource utilisation.
Advanced analytics and data-driven decisions
Real-time insights from traffic patterns and KPIs support proactive operations and reduce overheads. The integrated analytics enable efficient use of hardware resources, maximising ROI, as well as better decisions for new investments, protecting budgets.
Improved service reliability and QoE
WTL's DRA supports intelligent routing mechanisms to optimise Diameter message flows, minimising latency and ensuring timely delivery, enhancing efficiency and reliability. By ensuring seamless interaction between Diameter entities, WTL’s solution delivers more robust interconnectivity, reducing disruptions and boosting customer experience.

DRA
Mobility Management Entity
The MME controls user access and validating UEs during attachment and when roamers activate their devices. WTL’s MME is fully standards-compliant and scales to meet demand.
Network protection and authentication
The MME protects your network from unauthorised devices and visitors through interworking with the HSS. It manages transfer from 4G to legacy networks to ensure device connectivity when moving from one domain to another.
Cost effective and powerful
WTL’s MME solution can be delivered as part of our full EPC, or as a standalone component for multi-vendor networks. It’s ideal for greenfield deployments, for private / isolated networks, or for those dedicated to specific domains, like IoT. It provides a cost-effective solution for MVNOs that want to run hybrid networks.

MME
Serving Gateway
The SGW is the anchor point for user data sessions and is also essential for supporting handover between cells. It is vital for user experience, as it manages UE connections.
Inter-network compatibility
Our 3GPP-compliant SGW provides the link between 4G and other networks, giving you control over data services and QoS enforcement capabilities. Analytics from data flows provides you with more insight into sessions and helps support continuous optimisation.
High throughput and scalability
The WTL SGW can be deployed with a light footprint and then scales with your growth, so you can manage your investments and align with actual traffic and customer growth – so it’s an ideal starting point for MVNOs or for MNOs that are building out LTE but need to manage costs.
