Carriers' service delivery infrastructures cannot keep up with customer demand. The existing infrastructure, built on a network designed for a voice-centric, circuit-switched world, was not designed to create and deliver today's content-rich, integrated wireline and wireless packet-based services. Current infrastructure limitations create a "service bottleneck" that limits industry growth, increases churn, lowers average revenue per user (ARPU), and curtails service-based competitive differentiation. To remain competitive, carriers must find new ways to rapidly bring new data-rich telephony services to market, increase the quantity and variety of new available services, and rationalize their service creation and delivery process.
The solution that carriers are turning to is an open, standards-oriented, SIP-based Service Delivery Platform (SDP). Insulating the service developer from the underlying complexities of the network, SDPs streamline the deployment of new services, enabling providers to respond to market needs in less time and at lower cost.
Verscom Service Delivery Solution is built on the most trusted application infrastructure platforms in the telecom industry. The scalable infrastructure is combined with best-in-class service applications that are pre-integrated with the platform. This pre-integration streamlines the deployment of new services and ensures a flexible architecture for meeting future needs.
For service providers seeking to quickly deploy new data services, Verscom delivers the superior technology, applications, and services to meet your business objectives. This includes rapid service deployment for fastest time-to-revenue, service differentiation for better customer acquisition and retention, leveraging investments in network infrastructure and operational support systems, telco-proven, high reliability, and adaptability, reducing maintenance by creating a layer of abstraction above the physical network, and leveraging the legacy network in new and innovative ways.
Verscom Service Delivery Platform (SDP) solution represents an entirely new approach to deploying enhanced services in IMS-enabled, converged TDM/ IP and end-to-end VoIP carrier networks. Its open architecture and innovative use of next-generation network standards—including SIP, IMS, VoiceXML, MGCP, and XML—provide a multi-service platform with tremendous flexibility and scalability.
Key benefits of Verscom SDP solution:
-
Supports multiple hosted value-added services running side-by-side on industry standard hardware.
Enables rapid integration with any service provider network—pure IP or converged TDM/IP, wireless or wireline.
Accelerates development of new applications and features with industry-leading, standards-based software architecture.
Permits graceful, linear scaling to support up to millions of wireline and wireless subscribers and billions of minutes—with carrier-grade performance and reliability.
Delivers carrier-grade reliability and performance—with “five-nine” availability.
Enhances flexibility, enabling carriers to evolve their IP service architecture quickly and cost-effectively.
Reduces costs—as a pure IP solution, the RapidFLEX SDP eliminates costly TDM switches & fixed/mobile IN platforms, dramatically reducing capital and operational costs.
The Verscom SDP solution represents a comprehensive system, comprising both Runtime and Development-time functional software components including:
Application Server: Based on a pure IP design and running on industry-standard off-the-shelf hardware, the Application Server acts as the intelligent controller of switching, gateway, session control, and media server resources. At its core is a high-performance Service Logic Execution Environment (SLEE) built using XML-based scripts. Designed for high volume, high-performance carrier networks, the Application Server can run up to 7,000 concurrent call sessions on a single Linux system, or scale to extremely large call handling capacities by configuring multiple servers. The SDP also features stateful call migration, which allows call session states to be transparently duplicated in real time, protecting calls in progress in the event of an Application Server failure.
Service Creation Environment (SCE): The SCE is a visual service development environment that enables developers to build sophisticated NGN applications easily using drag-and-drop Plug-in Action Components (PACs) to enable various built-in operations, linking them in a visual call flow. This simple, intuitive interface makes applications faster to develop, customize, and modify to meet changing market needs.
Software Development Kit (SDK): The SDK is a software development kit that allows third parties to create their own Plug-in Action Components (PACs) that extend the software framework of both the Application Server and the Service Creation Environment, allowing developers to extend the capabilities of the SDP to add new protocols, APIs or custom features for their market specific applications.
Media Server: The Media Server is Linux-based IP media server software that offloads media processing functions—including voice announcement, recording, audio bridging, transcoding, and multilingual interactive voice response (IVR) capabilities—in SIP-enabled networks. It can be deployed as a standalone, IP-based media server solution in a SIP-enabled network, or used in conjunction with the Application Server to deliver multimedia services.
Session Border Controller: The Session Border Controller provides access network NAT Traversal and SIP endpoint registration for VoBB deployments where the subscriber’s VoIP endpoint device is behind a local firewall on premise.
Network Interface Unit (NIU): The Network Interface Unit acts as a stateless SIP proxy configured to receive incoming SIP network requests and hand them off to an available Application Server. In this role it serves two primary functions: 1) load balancing call traffic among all available Application Servers based on available capacity; and 2) monitoring continuous status of the Application Servers to detect failure conditions and route new call requests to the remaining Application Server clusters.
System Management Interfaces: It’s a Java-based GUI console providing platform operators with a single unified interface to all runtime software components of the SDP for all system configurations, operation, and monitoring tasks.
