  BARCELONA, SPAIN, Feb 25 (Marketwire) -- 
ST-Ericsson, a world leader in wireless platforms and semiconductors, and
Ericsson have successfully demonstrated the world's first dual mode high
definition VoLTE connection between LTE FDD and LTE TDD (TD- LTE) with
China Mobile today at the Mobile World Congress in Barcelona.

    The demonstration was conducted at China Mobile's booth using
ST-Ericsson's commercial Thor LTE multimode modem, and connected to
Ericsson's commercially verified LTE FDD/TDD converged network and mature
IMS platform.

    Mats H Olsson, President of Ericsson North East Asia said, "Ericsson is
honored to support China Mobile in setting up yet another milestone in the
development of TD-LTE. The technology readiness and commercial
availability of the system, platform and terminals of TD-LTE that we
demonstrated here is a strong testimonial of the maturity of a converged
end-to-end TD-LTE eco-system. Ericsson is determined to work continuously
with China Mobile and operators around the world to drive the
globalization and commercialization of TD- LTE."

    Mats Norin, Executive Vice President and Chief Technology Officer of ST-
Ericsson said, "ST-Ericsson is pleased to partner with China Mobile and
Ericsson in successfully demonstrating this great innovative milestone at
Mobile World Congress 2013. ST-Ericsson's Thor modem solutions and
NovaThor ModAp solutions are multimode platforms that are capable of
supporting TD-LTE/LTE FDD/WCDMA/TD-SCDMA/GSM. In addition, ST-Ericsson's
modem and ModAp platforms are able to provide complete voice solutions
including VoLTE, CSFB and SRVCC. We hope to continue our cooperation with
China Mobile to promote the development of TD- LTE."

    VoLTE uses IP packet-based network for voice call, it transmits voice into
data to carry out transmission, which enables a richer telephony
experience and high definition audio in combination with low power
consumption.

    According to GSA (Jan 2013), 61 mobile networks have launched HD voice
services in 45 countries. And there is a strong business case for Mobile
HD Voice. Customers make more, or longer, call with HD Voice, and highly
value the service. HD Voice helps operators to clearly differentiate
their offerings and enable high quality services to voice dependent
business like call centers, informationand emergency services..
