To develop and promote open-architecture, multiservice Next Generation Networks, GENBAND, a developer of IP infrastructure and application solutions, has participated in the GSMA backed MultiService Forum (MSF) Voice over LTE (VoLTE) Interoperability Test Event 2011 with the GENBAND A2(TM) Communications Application Server.
According to a press release, offering the role of VoLTE Telephony Application Server (TAS), the A2 provided Multimedia Telephony (MMTel) services with IMS to LTE mobile devices through 3GPP standard ISC and Ut interfaces.
“GENBAND's commitment to the VoLTE interoperability event, alongside Vodafone and China Mobile, highlights the significance of the combination of IMS and LTE for the telecommunications industry,” said Kyu-Ou Lee, MSF president. “The MSF and GSMA are working together to validate the standards to benefit the vendor and service provider ecosystem.”
The test event was hosted by MSF and GSMA operator members Vodafone and China Mobile in the Vodafone Centre.
GENBAND tested TAS functions using the ISC interface and successfully executed MMTel services to LTE devices via a third party IMS core. GENBAND also tested the Ut interface directly with the LTE devices for MMTel service configuration.
“The MSF/GSMA test event provides an ideal forum to validate core network interfaces that are essential to future multivendor deployment of LTE,” said Fred Kemmerer, chief technology officer at GENBAND. “We are pleased to have successfully conducted a broad range of strategic tests with our multi-service A2 platform, paving the way for not only core MMTel services for consumers, but also enabling unified communications for mobile business customers. These capabilities are being deployed in today's mobile networks in advance of LTE rollouts as networks prepare for migration.”
In other news, Interoute, the owner/operator of Europe’s most advanced and densely connected voice and data network, and GENBAND will deliver an official IPv6 VoIP network in Europe. Leveraging S3 Session Border Controller from GENBAND, Interoute will try and extend its existing Carrier IP Interconnect and SIP Business Trunking solution into its Next Generation IPv4 and IPv6 native network. Interoute plans to connect its operators and clients using IPv4 network with the ones using IPv6.
