Smart Serving Gateway


To provide seamless mobility for rich high data rate multimedia applications, between LTE eNodeBs and between LTE and other 3GPP technologies, Serving Gateway provides unprecedented multidimensional 4G performance and functionality. The radically different requirements of 3GPP EPC mandates a new breed of platform to serve as a Serving Gateway.  WiChorus, a Tellabs Company, is a pioneer in developing Intelligent 4G Packet Core platforms that enable world-leading EPC and Serving Gateway solutions.

Serving Gateway offers highly scalable termination point for all UE sessions, mobility anchor point for inter-eNodeB mobility and that between other 3GPP technologies.  Using its industry leading user plane and control plane performance with integrated content management and policy enforcement capabilities,  Serving Gateway gracefully provides the dynamic management of bearers, context management and management of Idle users.
