Ulticom provides carrier-grade service-enabling signaling software for wireless, wireline, and Internet communications. With more than 3,000 deployments in over 100 countries across six continents, Ulticom’s products are being used by more than 300 leading telecommunication equipment and service providers to deploy mobility, location, payment, switching, and messaging services.

Ulticom has over three decades of proven signaling expertise – it is our core competency. Our service-essential Signalware® software provides you with an unparalleled combination of scalability, global interoperability, fault tolerance, carrier-grade reliability, and standards-based APIs – all on open computing platforms.

 

The SIP architecture is modular and provides a simple, easy to use development environment for handling SIP session control. Ulticom’s carrier-grade Signalware SIP provides a complete development and deployment environment for customer-developed applications based on the SIP signaling protocols. This includes the combination of flexible SIP protocol access and platform management features that simplify the development process. Signalware SIP enables developers to maintain state information at either the transaction level or at the call level. Because it is modularized, the underlying transport protocol (UDP, TCP, SCTP) is transparent from the user application. This transparency hides the communication details so developers can concentrate on the application.

Signalware SIP

Ulticom’s carrier-grade Signalware SIP software is a robust solution that is built on the same proven fault-resilient platform as Signalware SS7 and Signalware SIGTRAN. Signalware SIP uniquely enables customers to build reliable systems ensuring no loss of revenue due to down time. Support is provided for Application Management, Load Sharing or Active/Standby Configurations, SIP Routing Function, and an optional Virtual IP feature.

Signalware SIP's high availability and scalability distinguish it from other SIP offerings. Features such as multiple computer element clusters (up to four CEs) and application failover and restart ensure revenue will not be lost due to downtime. Signalware SIP APIs can be added along side of SS7 or SIGTRAN signaling nodes to take advantage of Signalware's proven operational environment. Signalware SIP can also be deployed in a standalone environment, reducing product life cycle costs since one signaling platform supports multiple customer products.

Signalware applications can access the SIP protocol stack using any of three abstraction levels.

 

IMS-Ready Signalware

The IP Multimedia Subsystem (IMS) provides a reference architecture for operators to realize real-time communication services such as push to talk, ad hoc conferencing, and instant voice messaging. By abstracting the service and control functions from the access, this architecture will eventually be used to blend fixed and mobile capabilities creating a seamless service experience regardless of the communication device used by the subscriber.

As a trusted partner to network equipment manufacturers and application developers around the world, Ulticom supplies standards-based signaling solutions that simplify service creation and help promote service innovation. IMS-Ready™ Signalware will put you on the path to providing innovative new services to your customers.

In addition to support and services, the IMS-Ready Signalware package is a complete set of carrier-grade signaling software for the development and deployment of IMS network components and applications, including:

• SIP for multimedia session control and service management 
• Diameter to facilitate the exchange of subscriber data for authentication, authorization, and accounting and for service mobility management 
• GSM MAP and TIA/EIA-41 MAP to handle mobility management for interworking with 2.5G networks 
• CAP and WIN to create virtual home environments by interworking between IMS and CAMEL environments for service convergence 
• INAP and AIN for access to service logic in the legacy switched circuit network 
• SS7 and SIGTRAN for connectivity with existing signaling networks

 

 IMS Converged Services Gateway  (567kb)

The use of SIP as a common signaling protocol allows independent software developers to leverage a broad range of third party application servers, media servers, and SIP-enabled end user devices to create next generation services.
 

Signalware and Diameter

Ulticom offers support for the Base Diameter protocol and specific applications for IMS including the Cx and Sh interfaces. Since Diameter is easily extensible, customers can use the base specification to offer other applications or use the upper level AVP definitions defined by the 3GPP.

Signalware Diameter is designed with the same carrier-grade reliability, scalability, and portability as all the Ulticom products. Diameter, combined with SIP and SS7/SIGTRAN protocols, enables network equipment manufacturers to develop any IMS network element within a proven development and deployment environment. Signalware and Diameter advantages include:

• Secure, reliable signaling for IMS user authorization and service control 
• Easy integration with SS7 protocols like MAP, CAP, IS-41, and SIP 
• Faster time-to-market for service convergence gateway applications 
• Integration with Signalware management interfaces such as SNMP 
• Support for multiple applications per CE 
• Service continuity in case of online upgrade

Signalware SIGTRAN

Signalware SIGTRAN offers Network Equipment Providers an incremental approach to leverage the flexibility of IP networks while maintaining existing mobility, location, payment, switching, and messaging services on the Switched Circuit Network. By blending SS7 and packet protocols, Signalware SIGTRAN preserves current network architecture while laying the foundation for differentiating, revenue-generating services.

Signalware SIGTRAN is more than a protocol stack; it is an integrated platform that provides carrier-class qualities, including fault resiliency, scalability, out-of-the-box interoperability, and maintainability. Running on open computing platforms, Signalware SIGTRAN includes SCTP, M2PA, M3UA, and SUA as specified by the Internet Engineering Task Force. Leveraging experience in developing clustered SS7 Signaling End Point (SEP) platforms, Signalware SIGTRAN provides an Application Server (AS) and IP Signaling Point (IPSP) signaling framework with unique flexible clustering options. Signalware SIGTRAN key benefits and advantages include:

• SCTP provides carrier-class signaling characteristics to packet transport
• M2PA lowers network operation and management costs
• M3UA simplifies network engineering
• SUA streamlines transaction transport

Signalware Gateway

The Signalware Gateway is a bridge between the legacy circuit network and the all-packet NextGen network. Providing a portal between the two networks, the Signalware Gateway enables coexistence and interoperability for call set up and enhanced value-added services between monolithic switching platforms and the modular components in the NextGen network. It provides a complete, carrier-grade software solution for flexible, circuit-to-packet signaling interworking, offering network equipment vendors and service providers the flexibility for migrating platforms, applications, and services to evolving protocols and networks.

The Signalware Gateway provides the following advantages and benefits:

• Gracefully migrates from legacy SS7 
• Leads to efficient packet networking 
• Strategically positions operators for future all-IP network 
• Frees link capacity while maintaining reliability and stability 
• Deploys collocated IP-based IN applications and services 
• Reduces core network operating costs 
• Increases revenues / additional value-added services

 SIP to TCAP Gateway  (0.98Mb)

Next generation networks that are deployed using SIP need a simple way to access SS7 databases in order to offer comparable services to the incumbent fixed and wireless network operators. Signalware offers an integrated development platform for delivering SIP to TCAP gateway functionality. Signalware, SIP, and SS7 protocols can be combined to offer a gateway application on open Solaris® or LinuxTM based server platforms.
