SANTA CLARA, Calif. -- LongBoard, Inc., a leading provider of IP Multimedia Subsystem (IMS)-compliant software that powers the next generation of personalized multimedia services, is moving forward aggressively to enable carriers to deliver seamless IMS multimedia services across fixed and mobile networks.

LongBoard, which currently offers the industry's leading IMS-compliant solution for the seamless handover of voice calls across mobile and fixed networks, is adding new capabilities that enable seamless multimedia services. This includes unique new capabilities that provide carriers and mobile users with multimedia session continuity across multiple networks and devices with quality of service assurance.

IMS is an emerging reference architecture that enhances carriers' ability to quickly launch new, personalized multimedia services across a variety of access technologies. More than three dozen major carriers, including all major carriers in U.S. and Europe, have announced plans to deploy IMS services and are conducting technical trials of IMS products.

"We believe in the vision of IMS. We therefore have ensured that from day one that our software products are 100% compatible with emerging IMS specifications," said Hari Haran, CEO and President of LongBoard, Inc. "Our IMS-compliant software enables carriers to maximize the potential of IMS by offering subscribers revenue-generating converged services," he stated.

Interoperability with Leading IMS Vendors

LongBoard is working closely with leading Tier 1 networking equipment manufacturers to ensure interoperability between their IMS products and LongBoard's. This includes ensuring that the LongBoard Multimedia Application Platform (LMAP), the company's converged services platform, which includes the Call Continuity Control Function (CCCF), communicates with the Call Session Control Function (CSCF) in these vendors' IMS products via the standard IMS Service Creation (ISC) interface. In addition, LongBoard is ensuring that its software interoperates with the Home Subscriber Subsystem (HSS), the main centralized database that holds all the end user information, via the SH interface.

VCC-Compliant Mobile Call Handover

LongBoard's commitment to IMS starts with OnePhone, an IMS-compliant solution for seamless handoff of voice calls between cellular networks and 802.11 (WiFi) networks. OnePhone complies fully with the Third Generation Partnership Project's (3GPP) emerging Voice Call Continuity (VCC) specification (3GPP TS 23.806). LongBoard is working with key partners such as Stratus Technologies, HelloSoft, and Ecrio to deliver a comprehensive client/server solution for seamless mobility.

Seamless Mobility for Multimedia

LongBoard is bringing to market new IMS software that enables continuous multimedia sessions across heterogeneous networks and devices. This software ensures that mobile users' multimedia sessions won't be compromised or the session dropped as mobile users move across different access networks. This is key to ensuring quality user experiences and boosting Average Revenue Per User (ARPU), the main driver for carriers' moving to the IMS architecture.
