Ericsson Virtual Session Border Gateway Certified

vSBG is a high-performance carrier-class session controller product. It provides the ability to correlate all signaling and media streams (such as audio and video) that pass the network borders, hence providing a comprehensive suite of functions required to access and interconnect IP core domains (for example, IMS) and other IP networks with preserved security, privacy, and Quality of Service (QoS). SBG can be deployed in different roles and at different locations in various IMS-based architectures. 3GPP (IMS was originally standardized in 3GPP) have specified IMS-based architectures with network border functional entities, such as Proxy-Call Session Control Function (P-CSCF) and Interconnection Border Control Function(IBCF).
