Mobile Data Offload
As a market leading provider of Fixed Mobile Convergence (FMC) solutions, GENBAND offers a rich suite of Mobile Data Offload solutions to support service providers as they tackle the exponential growth of mobile data consumption driven by the increase in smart phones and intelligent wireless devices.
Over the past few years smartphones have exposed consumers to mobile internet and rich data services such as mobile video. With the unprecedented growth in new mobile data applications as well as subscribers’ appetites for them, mobile networks are seeing significant network congestion not only due to the increase in the number mobile broadband consumers, but also the usage per customer.
There are various technologies that the operators are leveraging to alleviate network traffic congestion. Wi-Fi and Femtocells are two of the leading key technologies for offload.
The 3GPP I-WLAN standard offers a compelling technology solution for integrating Wi-Fi networks with cellular networks and offloading mobile data traffic. The IWLAN standard provides two modes of interworking, namely Tunnel Termination Gateways (TTG) and Packet Data Gateways (PDG). Termination Gateways (TTG) can be used to access value-add operators’ hosted services from the Wi-Fi domain. Packet Data Gateways (PDG), on the other hand, offload internet traffic without accessing the operator’s core. Both modes are capable of applying service-based local policy for enforcing QoS.
For Wi-Fi based offload solutions, GENBAND’s S-Series Security Gateways can be configured as I-WLAN Tunnel Termination and Packet Data Gateways that work in conjunction with AAA servers and policy controllers to provide intelligent control of data and multimedia traffic. In addition, data session continuity and mobility is provided through support for MOBIKE and Mobile IP.
In addition to I-WLAN based offload solutions, operators are also using Generic Access Network (GAN), pre-Iuh and Iuh femtocell standards-based mobile data offload solutions. In these solutions, mobile data is typically offloaded at the Wi-Fi access points or femtocells. Operator hosted services can be accessed securely via Femto Gateways and GAN Network Controllers and Gateways residing within the operator’s core network.
GENBAND’s S-Series Security Gateways and G9 Converged Gateways support Generic Access Network (GAN), pre-Iuh and Iuh femtocell standards-based data offload solutions simultaneously, providing operators maximum deployment flexibility.
