The International Multimedia Telecommunications Consortium (IMTC) has completed Voice over LTE (VoLTE) interoperability testing over LTE network.
In SuperOp! 2011, a testing event of the telecommunications industry for multimedia communication standards and products, more than 70 engineers from 22 multimedia communication companies participated in week-long interoperability testing exercise in Waikoloa, Hawaii.
IMTC SuperOp! 2011 testing covered equipment and service interoperability on combinations of IP, 3G and LTE networks, and covered a broad range of technologies such as Voice over LTE (VoLTE) and IMS, HD Videoconferencing, TIP, Telepresence, HTTP Live Streaming (both Microsoft and Apple varieties) and traditional RTSP Streaming, as well as full spectrum of SIP-based and H.323-based videoconferencing systems.
IMS Activity Group conducted first ever multi-device Voice over LTE (VoLTE) interoperability testing over a live LTE infrastructure. Ericsson, Huawei, Intel Mobile, RADVISION, Samsung and ST Ericsson participated in the testing. Network elements to include LTE enhanced radio access (eNB), Evolved Packet Core (EPC), and IMS were provided by Huawei:
VoLTE testing included LTE voice call establishment, supplementary services (such as OIP, OIR, TIP ,TIR, HOLD and 3-way conferencing) and connectivity to legacy services.
VoLTE testing plan had being developed by the IMS AG which includes AT&T, Alcatel-Lucent, Ericsson AB, Huawei, Nokia, Nokia Siemens Networks, Orange-FT, Qualcomm, RADVISION, Samsung, Sony Ericsson and ST Ericsson.
