Nokia Session Border Controller (SBC) gives communications service providers (CSPs) economical and reliable means to secure and control media and signaling streams that cross the edges of the IMS network.

Nokia SBC sits at the edge of the access networks to secure any type of IP accesses and deliver all IMS services.
It also sits the edge of the peering networks to support roaming, IMS interconnection or corporate SIP trunking scenario.

You can deploy Nokia SBC either on-site on commercial off-the-shelf (COTS) IT servers or fully in the cloud:

• The integrated vSBC is designed in a scaled-down 2 x 2U form to increase capital and operational savings and optimize power with a small physical footprint
• The decomposed vSBC is designed in a large-scale 10U form and enables independent scaling of the signaling and media planes for greater capital expenditure savings
• The cloud SBC is designed for OpenStack and VMware Telco-cloud environments. The SBC VNF components (VNFC) scale up and down independently in real-time to meet fluctuating service demands, enabling unmatched operational efficiency
