With the explosive growth in mobile data traffic on 3G networks, service providers want more control over how to manage congestion—particularly in urban areas where the majority of traffic is handled by a few cell sites. 3G-Wi-Fi offload is a solution that allows operators to offload 3G traffic to available hotspots.
The Amdocs Policy Controller and Amdocs' Subscriber Data Broker™ play pivotal roles in helping operators address challenges around efficiently offloading subscribers by:
- Detecting locations with Wi-Fi availability;
- Turning on Wi-Fi radios selectively when needed and turning them off to conserve battery life;
- Implementing intelligent policy decisions over which type of traffic to offload; and
- Bringing control right to the device thus avoiding excessive signaling overhead to the core network.
Amdocs' client-based policy solution is unique. It leverages the device as the policy enforcement point to render precise, real-time policy decisions that govern when traffic is offloaded to Wi-Fi. This approach gives operators the level of control needed to manage congestion locally while ensuring a high quality subscriber experience.
