Broadband wireless networks are approaching saturation due to an explosion of traffic spurred by smart phones and wireless dongles. If not addressed with traffic offload solutions, congestion leads to poor quality of experience and ultimately customer churn.
However, adding capacity to the wireless core network can be a significant investment and thus operators are looking at different approaches to deliver more capacity more cost effectively.
Radisys can empower network equipment providers to incorporate Internet Offload / Traffic Offload Gateway functionality to provide congestion relief for the wireless core network. By identifying and routing certain classes of traffic directly to the Internet rather than via the wireless core network, operators can increase customer satisfaction and delay costly core capacity upgrades. An Internet Offload / Traffic Offload Gateway is flexible in its deployment options and is applicable to both LTE and 3G wireless networks.
Internet Offload / Traffic Offload Gateways are deployed at the edge, connecting via the IuPS (3G) or S1 (LTE) interfaces and associated control plane protocols. Based on application identification, pre-provisioned policy decisions result in traffic either being forwarded to the core network or else “offloaded” directly to the Internet without entering the wireless core network.
