One of the main attractions of the SuperOP! 2011 was the first ever multi-device VoLTE call over live LTE equipment supplied by Huawei – LTE enchanced radio access (eNB), Evolved Packet Core (EPC) and IMS core.

During SuperOp! 2011, for the first time ever, Voice over LTE testing was conducted by Ericsson AB, Huawei, Intel Mobile, RADVISION, Samsung and ST Ericsson over a live LTE. Complete infrastructure to include LTE enhanced radio access (eNB), Evolved Packet Core (EPC), and IMS were provided by Huawei. “This year’s event was a significant milestone in demonstrating for the first time ever, a successful VoLTE interoperability on a common User Network Interface (UNI) in a live LTE infrastructure. A fully interoperable and high quality voice service is fundamental to operators globally, and Huawei is honored to be a part of the effort in realization of that goal by providing our end-to-end VoLTE solution,” said Rouzbeh Farhoumand, Senior Director of Huawei and an IMTC Board of Directors Member.
Voice over LTE testing plans had being developed by the IMTC IMS Activity Group, which was designated by GSMA, the owner of the GSMA PRD IR.92 VoLTE specification, as leading testing group.
Testing during SuperOp! 2011 covered areas such as LTE voice call establishment, supplementary services ( OIP, OIR, TIP ,TIR, HOLD and 3-way conferencing) and connectivity to legacy services. “Voice over LTE is gaining momentum, and there is a clear need for interoperability before commercial services can be deployed” said Tsahi Levent-Levi, IMS Activity Group Co-Chairman and CTO of Technology Business Unit for RADVISION, ”Testing over a live LTE network at the SuperOp! 2011 is an important milestone that we have successfully achieved.”
The IMTC IMS Activity Group continues to develop testing plans for VoLTE IR.92 and plans to conduct additional VoLTE interoperability testing events this year, both independently and in cooperation with other industry consortia such as MSF and ETSI. Current members of the IMS Activity Group include AT&T, Alcatel-Lucent, Ericsson AB, Huawei, Nokia, Nokia Siemens Networks, Orange-FT, Qualcomm, RADVISION, Samsung, Sasken Communication, Sony Ericsson and ST Ericsson. The IMTC IMS Activity Group likes to reiterate its open call for participation for all operators and equipment manufacturers to facilitate VoLTE service delivery world-wide.
IMTC’s SuperOp! 2011 was hosted by IMTC with event management from Global Inventures. Sponsors included Cisco, Polycom, Huawei, UCIF and Vidyo. Next SuperOp! interoperability testing event is expected to take place during April/May 2012 timeframe, location will be announced at a later date.
