GENBAND Showcases RCS Voice over LTE Capabilities at MSF/ETSI/GSMA Interoperability Test Event

Frisco, Texas, October 10, 2012GENBAND, a leading developer of IP infrastructure and application solutions, today announced its participation in the Rich Communication Suite (RCS) Voice over LTE (VoLTE) Interoperability Test Event organized by MSF, ETSI and GSMA. The A2™ Communications Application Server  is functioning as the VoLTE application server and RCS application server during the tests, which are being conducted using LTE radio access network infrastructure equipment.

The RCS VoLTE IOT Event is being hosted by China Mobile at the China Mobile Research Institute Laboratory in Beijing, China and by Telecom Slovenia Group in Sintesio, Kranj, Slovenia. The GENBAND Application Server is being deployed in both locations.

“Today service providers are actively examining options for offering the latest RCS VoLTE capabilities and this leading interoperability test event is an ideal forum for GENBAND to showcase the comprehensive carrier-ready capabilities of our A2 Application Server,” said B.G. Kumar, President of GENBAND’s Multimedia Business Unit. “As customers look to deploy RCS VoLTE services, they can rely on the A2 platform to provide the most comprehensive set of IP applications, including business VoLTE services, extensive fixed and mobile services, and support for web clients.”

As the VoLTE application server for the event, the A2 Communications Application Server is providing MMTEL voice service, integrated SCC (service centralization and continuity) and MRF (media resource functionality). It is also supporting the Ut interface, enabling VoLTE clients to control MMTEL services user settings.  Acting as the RCS application server, the A2 is supporting OPTIONS-based capability discovery, video sharing, image-sharing and instant messaging via session and pager mode.

GENBAND’s market-leading application server is the only application server that has fully integrated multimedia applications for voice, video, conferencing, instant messaging, presence, collaboration and mobility. The A2 is also the only application server that works in TDM, IP and IMS networks simultaneously for hybrid network deployments. The A2’s integrated wireless mobility manager allows for mobile integration with any mobile phone for services such as fixed mobile convergence, voice over LTE, Mobile Office and mobile unified communications.

“The RCS VoLTE Interoperability event reflects the MSF’s commitment to carrier-driven interoperability events that validate key emerging standards and technologies, including key network interfaces that ensure multi-vendor deployment strategies for RCS/LTE/EPC/IMS technology,” said Kyu-Ouk Lee, MSF President. “We are pleased that GENBAND is participating at the 2012 event.”

Backed by major operators China Mobile, Verizon and Telecom Slovenia, the event builds on the success of the previous MSF VoLTE Interoperability Event that took place in September 2011. Continued support of interoperability events reflect the commitment of the MSF, ETSI and GSMA to conduct important carrier-driven events that benefit all members in their quest to keep in front of the pace of change in a quickly evolving industry.
