   Date:2011/10/26

25 October 2011, Shenzhen, China - 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 it has successfully participated in the first-ever voice over LTE (VoLTE) interoperability test event hosted by the MultiService Forum (MSF) and backed by GSMA at the Vodafone Test and Innovation Centre in Düsseldorf, Germany.

The test event centered on validating key network interfaces to ensure multi-vendor deployment strategies for LTE/EPC/IMS technologies, including GSMA's technical recommendations for IMS-based VoLTE. Test scenarios included VoLTE basic interoperability, global roaming and interconnection as specified by the GSMA.

ZTE provided end-to-end system and terminals for the test, including: IMS Core (P/I/S-CSCF), eNodeB, MME, S-GW, P-GW, PCRF, HSS, DRA, IMS MMTel AS, IMS soft client and LTE UEs. ZTE supplied comprehensive network solutions for VoLTE IMS calls.

During the test, VoLTE calls were successfully completed at and between two host sites (including MMTel services). LTE roaming between host sites also was demonstrated successfully through the use of dynamic policy control between home and visited networks that employed Diameter Routing Agents (DRA).

"We are pleased with the results of the MSF VoLTE IOT event because it has laid the foundation for actual deployment of VoLTE," said ZTE Core Network Products Vice President Wang Xiaoqiang. "ZTE is committed to investing in VoLTE and working with LTE operators to achieve innovative voice applications over the LTE network."

"ZTE'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."

ZTE is one of the world's leading vendors of VoLTE technologies and systems. The company provides LTE operators with an IMS-based architecture that enables the deployment of voice and multimedia services. This open system allows developers to build a wide variety of applications. Available services include: voice services, IM/PS/GM, HD video conferencing, video surveillance and RCS.

In cooperation with the GSMA and Hong Kong operator CSL, ZTE successfully established the world's first IMS VoLTE call based on a commercial LTE network and existing 2G/3G networks in November, 2010, at the Mobile Asia Congress.
