Smart PDN Gateway 


The increasing use of multimedia-rich applications on the move require advanced mobile broadband technology like 3GPP LTE to satisfy the demand.   LTE EPC (Evolved Packet Core) is the bedrock for offering rich revenue-generating services over LTE networks.  The EPC in 3GPP brings radical changes in the underlying requirements to build a differentiated LTE mobile core network, requiring a new breed of platform with new multi-dimensional performance and functionality requirements. 

WiChorus, a Tellabs Company, is a pioneer in developing Intelligent 4G Packet Core platforms that enable world-leading EPC and PDN Gateway solutions.   PDN Gateway offers highly scalable mobility anchor point that delivers high data and control plane performance with integrated granular content management and policy enforcement capabilities.
