Easing Network Congestion

Radio access network (RAN) congestion is increasing, driven by the rapid growth in mobile data traffic, traffic concentration in urban centers, heavy users, and video applications. This congestion strains network resources and negatively impacts your subscribers’ quality of experience (QoE), which can increase churn. Maintaining optimal QoE takes more than simply mitigating RAN congestion.

With Tekelec’s unique RAN-Aware Policy Management solution, you can improve your customers’ experience by combining historical and real-time network performance data with subscriber profile, device, application, and location information to define policies in real time.

Proactively manage network congestion in real time, using three key steps:

• Analyze the activity on your network and QoE with Tekelec’s Performance Intelligence Center (PIC). Real-time and historical metrics from several data sources - including signaling and user-data probes - identify issues and provide the input required for unparalleled levels of network decision making.
• Decide where and how to handle traffic. The solution couples Tekelec’s Subscriber Data Management system, a real-time source for data and customer information, with its sophisticated Policy Server (PCRF) product, which applies business rules based on subscriber data and optimizes traffic through routing and load balancing.
• Act on the decision to dynamically tune or balance traffic flows to ensure that high-priority traffic or latency-sensitive traffic is delivered with a guaranteed quality of service (QoS) and give premium subscribers priority.

Tekelec’s RAN-Aware Policy Management solution improves your subscriber QoE and guarantees service levels by prioritizing subscribers based on entitlements, service tier and device or application usage. It provides transparent notifications to alert your subscribers to network conditions and service options such as a service-tier upgrade, alternative access such as Wi-Fi or a temporary bandwidth boost.
