Sonus Networks, Inc. (Nasdaq: SONS), a global leader in enabling and securing real-time communications, today introduced the award-winning Sonus embedded Diameter Signaling Controller (eDSC). With the Sonus eDSC, mobile network operators (MNO) can leverage advanced DSC and SS7 capabilities found in standalone platforms by simply activating a software license on the Sonus SBC 5110, Sonus SBC 5210 or Sonus SBC 7000 Session Border Controllers (SBCs).

Diameter, the industry standard for data signaling, and Session Initiation Protocol (SIP), the industry standard for message signaling, work in tandem to provide the signaling needs for Long-Term Evolution (LTE) networks. With the advent of click-to-connect, real-time applications for voice, video and collaboration services, both Diameter and SIP traffic have been rapidly growing as more subscribers drive data and voice over IP-based (VoIP) mobile networks. This signaling traffic, in turn, has hastened the need for centralized controllers that can help MNOs manage this latency sensitive traffic in a more intelligent, secure and scalable manner.

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. For MNOs looking to normalize these protocols at their ingress/egress point, an integrated SBCDEA solution helps provide increased network operational efficiencies and performance improvements by integrating common security, interworking, interconnect and network management functions.

Sonus SBCs help mobile operators deliver a high Quality of Experience (QoE) in Voice over LTE (VoLTE) networks with support for high-definition (HD) voice and SIP signaling control and media anchoring to ensure seamless voice call continuity across networks. Additionally, Sonus 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.

In addition to full SBC and DSC functionality, the Sonus eDSC provides 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. The integration of SBC, DSC and IWF functionality onto a single platform allow LTE service providers to simplify network management, reduce network complexity and speed the roll out of advanced IP-based services for real-time communications.

The Sonus eDSC expands the Sonus Diameter portfolio, giving MNOs greater flexibility to deploy hardware (DSC 8000), SBC integrated (eDSC) or virtualized (DSC SWe) Diameter solutions to best address their business needs.

“Click-to-connect type applications that sit on smartphones, tablets and computers are driving significant amounts of Diameter signaling traffic across LTE networks,” said David Tipping, vice president and general manager, Products, Sonus. “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,” said Diane Myers, principal analyst, Infonetics Research (part of IHS Inc.). “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.”

Other Facts:

  • The Sonus eDSC received the “Best VoLTE Innovation” at the 2014 LTE North America Awards. The product was recognized for innovation specific to virtualizing and joining together the features of a DSC with an SBC to help simply and seamlessly enable and secure VoLTE services. A panel of eight leading industry experts independently judged the competition.
  • Infonetics Research, part of IHS Inc. (NYSE:IHS) , forecasts the global DSC market to grow from $381 million in 2014 to $1.3 billion in 2018, in line with the growth of mobile broadband traffic within and between operators.
