12 April 2011, Barcelona, Spain – ZTE Corporation (“ZTE”) (H share stock code: 0763.HK / A share stock code: 000063.SZ), a publicly-listed global provider of telecommunications equipment and network solutions, today announced at IMS World Forum 2011 that it will participate as a Gold Sponsor in the first ever MSF/GSMA VoLTE (Voice over LTE) Interoperability Event scheduled for September 2011 in the Vodafone Test and Innovation Centre in Düsseldorf, Germany.

"We are delighted to work with the MSF and the GSMA on this world first VoLTE interoperability test, which will deliver real value towards the deployment and implementation of VoLTE for operators," said Mr. Wang Xiaoqiang, Vice President of ZTE Core Network Products. "ZTE has extensive expertise in the field of voice services for LTE network operators and is committed to heavily investing in VoLTE to offer continuously innovative VoLTE solutions, including the newly-launched zVOA solution."

The zVOA solution is composed of the iCX (intelligent Controller eXtensive) and iMG (integrative Media Gateway) products which are able to offer normal CS (CircuitSwitching) services as well as VoLTE services including SRVCC (Single Radio Voice Call Continuity) and CSFB (Circuit Switched Fall Back). All the CS/IMS related signaling elements and media plan elements such as SBC, MGW run on one shelf to enable flexible networking and simplified network architecture for operators.

The MSF VoLTE Interoperability test event will focus on validating key network interfaces to ensure multi-vendor deployment strategies for LTE/EPC/IMS technologies. A key objective of the testing is to validate the GSMA's technical recommendations for IMS-based VoLTE. Test scenarios include VoLTE basic interoperability, roaming and interconnection, non-LTE Access to EPC (e.g. GERAN/UTRAN), handover/relocation and Self Organizing Networks (SON).

ZTE is the world's leading vendor of VoLTE technologies and systems. ZTE provides LTE operators with an ideal IMS-based architecture to deploy voice and their own multimedia services and, as it is an open system, other application developers can build a wide variety of applications to run on the system. Rich services include voice services, messaging services, HD video conferencing, video surveillance and RCS. With the GSMA and Hong Kong operator CSL, ZTE successfully established the world's first VoLTE call based on IMS between LTE network and the existing 2G/3G networks in November, 2010 at the Mobile Asia Congress.

"We're delighted that ZTE is supporting this industry-first VoLTE testing activity, and we look forward to a fascinating and challenging event in Düsseldorf that will help define the future of mobile communications," said MSF President Jim McEachern.
