BARCELONA, SPAIN -- (Marketwire) -- 02/25/13 -- 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..
