Additionally, Sonus said its SBCs provide scalable signaling interworking, media transcoding, signaling and media encryption, policy enforcement, topology hiding and denial of service (DoS) protection needed in VoLTE networks.
Sonus Networks, a global leader in enabling and securing real-time communications, has introduced an embedded Diameter Signaling Controller (eDSC) software that will allow mobile network operators (MNO) to leverage advanced DSC and SS7 capabilities found in standalone DSC platforms. The eSBC can be activated via a software license on the Sonus SBC 5110, Sonus SBC 5210 or Sonus SBC 7000 Session Border Controllers (SBCs). In addition to full SBC and DSC functionality, the Sonus eDSC is designed to provide interworking (IWF) between Diameter and legacy SS7 systems, enabling 2G and 3G networks to deliver smoother operations of dual technology, ensuring a high QoE for subscribers.
According to Sonus, the Sonus eDSC is designed to address these demands by enabling MNOs to solve the Diameter routing issue, while also securely delivering SIP-based, real-time communications like voice, video and collaboration services, from the same platform. Much like the functions a SBC provides for SIP at the peering edge between two operators, a Diameter Edge Agent (DEA) does the same for Diameter. Sonus added that for MNOs looking to normalize these protocols at their ingress/egress point, an integrated SBC/DEA solution helps provide increased network operational efficiencies and performance improvements by integrating common security, interworking, interconnect and network management functions.

Click-to-connect type applications that sit on smartphones, tablets and computers are driving significant amounts of Diameter signaling traffic across LTE networks. The increased congestion, paired with the SIP-based traffic of voice and video, has put new strains on LTE networks worldwide. The Sonus eDSC uniquely solves this challenge, by integrating the capabilities of a DSC and SBC on one common platform, allowing MNO to solve the Diameter dilemma, while also reducing the complexity of their network and saving money.

The increased use of mobile broadband networks is driving the growth of Diameter signaling within and between operators. This signaling traffic, in turn, has hastened the need for centralized controllers that can help manage the traffic in a more efficient and scalable manner. With the addition of the eDSC to its portfolio offering, Sonus provides service providers greater flexibility to deploy hardware, virtualized or SBC-integrated Diameter solutions to best meet their business needs.
