Enhance policy control with subscriber awareness for a seamless and contextualized mobile experience
As the breadth of operator connectivity and digital services continues to grow, policy control is becoming a critical enabler in supporting the management of plans and subscribers. From data bundles and 5G slices to IoT plans, operators rely on various policy control functions in the mobile core to authenticate subscribers and account for the use of valuable network resources. Given the complexities of managing hundreds of millions of subscribers and end nodes, operators are starting to recognize a greater need for subscriber awareness or session awareness that enables policy control functionalities such as authentication and charging to be implemented securely, reliably, efficiently and in real time. Coupling these 5G policy control functions with intelligent load balancing that delivers such awareness has become a prerequisite for seamless access to and the effective delivery of mobile services.
Improved plan management and enhanced fraud protection with GTP correlation
With our GTP Subscriber Resolving Module (R&S®GSRM), operators can incorporate subscriber and session awareness into the mobile core network across LTE and 5G NSA networks. R&S®GSRM correlates the GTP control plane with the GTP user plane to deliver real-time identification of packets by sessions and subscribers. Network packet brokers (NPBs) leverage data gathered by R&S®GSRM to filter and aggregate packets from a single session or subscriber and to forward an entire session to a single policy control device.
This enables functions such as AAA, convergent charging, mediation and rating. These functions are hosted on service-chained sub-systems to receive a session in whole, meaning in a single forwarding instance for complete visibility. This, in turn, permits operators to implement granular access control for different users and plans across different sessions. 5G policy control functions help to implement the integrity of your network infrastructure and enhance network security with access control and real-time threat protection. What is more, it rectifies 5G network security vulnerabilities.
Subscriber awareness also greatly accelerates the speed at which user sessions are aggregated for rating and charging purposes and ensures greater accuracy in accounting for usage. Through the use of R&S®GSRM, policy control functions also benefit from higher processing consistencies (e.g., charging) within a subsystem. Ultimately, subscriber-aware policy control helps tailor the network experience to better suit the user’s individual needs.
Subscriber-aware policy control enables:
- Fine-grained subscriber-based and session-based access policies
- Granular access policies for concurrent access to operator digital and multi-play services
- Differentiated access and network usage policies (micro policies) within shared/private 5G/IoT plans
- Support for ZTNA and SASE implementations on private networks
- Real-time prevention of fraud and network abuse
- Contextualized and personalized offers
- Dynamic rating based on session attributes such as location, applications and content
- Real-time convergent charging across multiple service types
- Proactive notifications and alerting for overage prevention
