Ulticom Unveils New IMS-Ready Signalware Package

Launches Comprehensive Program to Accelerate Converged Fixed-Mobile Applications

At the 3GSM World Congress conference, Ulticom, Inc. , the premier provider of signaling software solutions, today announced a comprehensive program to help accelerate the deployment of fixed-mobile solutions that utilize the IP Multimedia Subsystem (IMS) architecture. IMS is rapidly becoming the de facto service delivery architecture for fixed, wireless, and cable networks. Based on the widely deployed Signalware platform, the IMS-Ready Signalware package combines products and services designed to address the complex challenges associated with implementing communications services in a converged network environment.

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 combines the comprehensive Signalware development and deployment environment with subject matter consultation to support a staggered and varied migration path toward an IMS architecture driven by specific service provider needs.

The cornerstone of the package is a complete set of carrier-grade signaling software necessary for the development and deployment of IMS network components and applications:

--  Session Initiation Protocol (SIP) - Enables multimedia session control
    and service management
--  Diameter - Facilitates the exchange of subscriber data for
    authentication, authorization, and accounting (AAA) purposes and service
    mobility management
--  GSM Mobile Application Part (MAP) and TIA/EIA-41 MAP - Provide the
    mobility management basis for interworking with 2.5G visited networks
--  CAMEL Application Part (CAP) and Wireless Intelligent Network (WIN) -
    Create virtual home environments for roaming subscribers by interworking
    between IMS and legacy CAMEL environments for service convergence
--  Intelligent Network Application Part (INAP) and Advanced Intelligent
    Network (AIN)  - Allow access to service logic residing in the legacy
    switched circuit network
--  SS7 and SIGTRAN - Provide connectivity with existing signaling
    networks
    

Key to the IMS-Ready program is the inclusion of Ulticom's highly skilled professional services consultants to help customers implement creative approaches that maximize return on investment and provide a seamless service experience. Backed by Ulticom's world-class customer care organization, this comprehensive program enables the rapid delivery of IMS applications in a manageable, phased approach.

"Service providers will be compelled to adapt to an IMS-based network architecture to protect and leverage their existing value proposition," said Shawn Osborne, president and CEO of Ulticom. "IMS-Ready Signalware simplifies the task by providing a common, reusable, and flexible infrastructure that allows vendors to focus R&D resources on their core value-added capabilities."

"As the industry moves towards all IP-core networks, service providers must integrate next-generation services with existing network infrastructure to ensure a consistent user experience," said XJ Wang, senior analyst at The Yankee Group. "To help fill the gap, IMS vendors can benefit from Ulticom's proven expertise in providing carrier-grade software and services when developing IMS network components."

The IMS-Ready Signalware package will be featured this week in the Ulticom booth (Stand D25, Hall 2) at the 3GSM World Congress conference in Cannes, France. For additional information on IMS-Ready Signalware, please visit www.ulticom.com/IMS.
