ZTE and Imagination Technologies announce availability of VoLTE on commercial handsets

MWC, 26th
February 2013 –
Imagination Technologies (IMG.L), a leading multimedia, processor, communications and cloud
technologies company, and ZTE
Corporation (“ZTE”) (H share stock code: 0763.HK / A share stock code:
000063.SZ), a publicly-listed global provider of telecommunications equipment, network
solutions and manufacturer of handsets/smartphones, today announce the
HelloSoft VoLTE solution is now available on commercial ZTE VoLTE-enabled
handsets, powered by the MetroPCS 4G LTE network.

ZTE handsets with the embedded HelloSoft
VoLTE client are available at MetroPCS stores in the Dallas (USA) region.

Imagination’s HelloSoft VoLTE is fully
standards-compliant with 3GPP Voice over LTE and GSMA IR.92 specifications. It
incorporates award winning multiplatform HelloSoft VoIP, IMS, VCC, and VoLTE
technology featuring AEC (Acoustic Echo Cancellation) and NC (Noise
Cancellation) to produce superior voice quality on 4G mobile devices.
Imagination’s HelloSoft VoLTE is deeply integrated into the handset and with
the handset native dialer to provide a low-latency, superior voice and video
user experience. HelloSoft VCC (Voice Call Continuity) technology enables
seamless handoff of VoIP and circuit switched calls across 4G/3G/2G networks
and also between multiple IP networks such as LTE and WiFi.

Says Tony King-Smith, VP marketing,
Imagination: “Great teamwork with ZTE has produced a superior quality embedded
VoLTE solution. Unlike over-the-top clients, it is essential to work closely
with the operators, handset manufacturers and other ecosystem partners, including
the chipset providers and infrastructure vendors, to deliver an optimized, low
latency integrated VoLTE client.”

Says Lixin Cheng,
CEO, ZTE USA, and president, North America Region, ZTE: “ZTE has made LTE
handsets a priority in the U.S. market for 2013. Our partnership with
Imagination and MetroPCS will enable our LTE handsets to feature the many benefits
of VoLTE, offering consumers a significantly enhanced user experience.””

ZTE is one of the world’s leading vendors
of LTE technologies, systems and handsets. The company provides LTE operators
with an IMS-based architecture that enables the deployment of voice and
multimedia services.
