Interoperability Testing of Voice over LTE (VoLTE)
March 30, 2011 By 1 Comment
International Multimedia Telecommunications Consortium (IMTC) is pleased to announce that interoperability testing of Voice over LTE (VoLTE) will be one of the key focus areas during their flagship SuperOp! 2011 interoperability testing event in Kona, HI, May 15-20. IMTC’s VoLTE testing will focus on terminals and core network interoperability. IMTC invites all interested parties to participate in this engineering test event.
IMTC has a special area of interest with VoLTE testing. While other organizations may test VoLTE on network interfaces, IMTC has a keen focus for VoLTE testing on terminals and with the core network. This makes the IMTC SuperOp! 2011 testing event unique, and one of the few places to actually accomplish this level of engineer to engineer interoperability testing. A complete network inclusive of LTE access is being hosted by Huawei at the May 2011 SuperOp!, and IMTC is inviting all terminal companies to participate including ST-Ericsson, Nokia, Samsung, Sharp, LG, RIM and others, as well as Operators with interest in VoLTE.
At the June 2010 SuperOp!, participating companies included Alcatel-Lucent, Cisco, LifeSize Communications, Nextreaming Corp., Nokia, NXP, Orange France Telecom, PacketVideo, Polycom, RADVISION, RealNetworks, TANDBERG Telecom, Vidiator Technology and Vidyo.

Full details including the ‘rules of engagement’ for this engineering only testing event can be found at the link above. This is a closed and confidential interoperability testing event, it is not a public event. Access to IMTC interoperability testing events is available to all IMTC member companies, and invited non-member companies who can contribute to the interop testing activities. IMTC member companies participate in ongoing development of the interoperability testing plans and specifications, organize and conduct face-to-face and virtual interoperability testing events on the regular basis, and provide feedback for improvements to national and international standardization bodies like ITU-T, 3GPP, IETF, GSMA and others.
SuperOp!, organized and conducted by the IMTC annually, is a significant event for the telecommunications, video conferencing and Telepresence sector. It brings together engineers from the leading companies developing unified communications, video communications products and services worldwide. The event includes equipment and service interoperability on combinations of IP networks, and covered a broad range of technologies such as HD Videoconferencing, Telepresence, mobile 3G-324M video, new 3G rate adaptation mechanisms in Packet Switch Streaming, SIP with BFCP and H.323 with H.239, and HTTP Live Streaming features.
About the International Multimedia Telecommunications Consortium (IMTC)
The IMTC is an industry-leading, non-profit organization whose mission is to promote and facilitate the development and use of interoperable, real-time, multimedia telecommunication products and services based on open international standards. The IMTC hosts interoperability testing events and demonstrations throughout the world. IMTC has hosted more than 50 such events to test SIP, IMS, VoLTE, H.323, 3G-324M, 3G-PSS, Nat/Firewall Traversal, T.120, H .320, and other Voice over IP products and services with each other. The IMTC Board of Directors includes representatives from AT&T, Cisco Systems, Ericsson, HP, Huawei, LifeSize Communications, Nokia, Polycom, RADVISION and Vidyo. The San Ramon, California-based consortium comprises approximately 40 member organizations from around the globe.

VoLTE – The first IOT event
February 22, 2010 By 1 Comment
At the 2nd of February in Stockholm, winter-time in the city filled with snow, the IMTC IMS AG (Activity Group) met F2F (Face to Face) for inter-operability activity. This time, our challenge was to help bringing IMS Voice over LTE (VoLTE, a single industry-wide solution for voice over LTE adopted by GSMA) to the market. [Read more...]
VoLTE and the IMTC

One of the important aspects of an open standard is the ability to rigorously test it for interoperability. And then when you’re done testing – test yet again. It is an ongoing process that never seem to end.
Take our 3G-324M AG at the IMTC – I’ve been an active participant of this group from its inception, and that was over 5 years ago. And this year, the 3G-324M AG is going to have some more testing done – it seems like there is no rest for engineers.
So now that the GSMA has decided to go full force and work on the VoLTE specification so that operators can start rolling out all-IP mobile networks and still provide the basic services they do today, there was a missing piece in the puzzle – they have the ecosystem, but not real place to use for interoperability testing amongst the vendors implementing VoLTE.
That’s exactly where the IMTC comes into the picture [Read more...]
A Short Introduction to VoLTE

A few years ago, when it seemed apparent that all communications are moving to an IP based world, mobile operators had to decide on the standard to use in their all-IP world. SIP was selected for that purpose as the base protocol, with a lot of additional protocols taking part to comprise the whole network. The end result (which is an ongoing standardization effort) is IMS – the IP Multimedia Subsystem.
IMS was adopted by all other incumbent service providers – wireline, wireless and cable, which in a way made sure of continuity of service, interoperability and roaming between operators. Fun as it is, the problem with IMS is its complexity: it comes to replace a hundred years of developments in voice technologies, and wrap into their future network advanced services such as rich multimedia and presence.
