Barcelona, February 26, 2013 - ST-Ericsson, a world leader in wireless
platforms and semiconductors, and Ericsson have successfully demonstratedthe
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

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

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..
