Ulticom Diameter Signaling Controller (DSC) -- Momentum Builds

MOUNT LAUREL, NJ and BARCELONA, SPAIN -- (Marketwired) -- 02/24/14 -- Ulticom, an industry leader in signaling solutions, announces a year of successful deployments of their Diameter Signaling Controller (DSC) and mounting market momentum.


  • A leading Telecom Equipment Manufacturer (TEM) is deploying Ulticom's DSC as both a Central Router and Diameter Routing Agent (DRA, includes support for Policy Management specialized routing) in all provinces of a Top 10 Mobile Network Operator. Ulticom's feature rich routing and DRA functionality paired with highly configurable congestion management capabilities set it apart from the competition. This TEM is deploying Ulticom's DSC on high performance blade hardware (tested at rates beyond 300,000 TPS) as part of a large Evolved Packet Core (EPC) deployment. The portability, adaptability, and very high performance of Ulticom's DSC solution were key factors in the selection process.

  • A Charging Solutions Provider is deploying Ulticom's DSC as a load balancing front end to a multi-server charging cluster. The Ulticom DSC's ability to perform load balancing, overload control, and intelligent transaction routing met the customer's essential requirements for fast and efficient charging system growth driven by subscriber demand for data rich services. Ulticom's Service-Oriented Routing™ goes beyond the typical primary-backup reliability strategy used for Diameter Signaling. Service-Oriented Routing creates pools of servers that can deliver a service acting together as a single logical entity. Ulticom's DSC transparently optimizes load distribution across the server cluster while dynamically compensating for congestion and failures within the server pool.


  • A top 5 Mobile Network Operator is deploying Ulticom's DSC in support of LTE Roaming allowing subscribers to utilize LTE devices not just in their home network, but also while traveling. Deployment of this functionality has already occurred in two major national networks operated by the carrier. Ulticom's DSC offers great deployment flexibility; one network is deploying on dedicated servers, while another is deploying in virtualized computing clusters. The flexibility of Ulticom's DSC to embrace virtualization where needed or simply be deployed in a more traditional server model was key to the carrier's many operational constraints.

  • Deployed in a major IPX Provider's network, Ulticom's DSC functions in both Diameter Edge Agent (DEA) and IPX Hub roles. This particular provider is focused on virtualized cloud-based service delivery models. The DEA functionality is being provided in support of multiple LTE Roaming forms, including as a cloud-based service to other MNOs. The Ulticom DSC's virtualization ready, hypervisor independent product was an ideal fit with the customer's requirements.


  • A fast growing Mobile Network Operator deployed Ulticom's DSC to manage Diameter transaction growth and routing for charging. The network operator sees the DSC deployment as a first step in their strategy to incrementally adopt IMS technologies and migrate to LTE. Using Ulticom's FastPath™ scripting technology, this operator was able to immediately work around incompatibilities between network equipment vendors and deploy a highly customized content-based routing strategy to enable load sharing in mere days.
