Ericsson and china mobile make the world's first dual mode HD voice over LTE call based on multi-mode chipsets
(Thomson Reuters ONE) -
* The world's first dual mode HD voice over LTE call between TD-LTE and LTE
FDD demonstrated
* Based on ST-Ericsson Thor LTE modem and Renesas Mobile' quad-mode chipsets
* LTE TDD/FDD converged network infrastructure provided by Ericsson
Ericsson has successfully supported China Mobile in demonstrating the world's
first dual mode HD voice over LTE (VoLTE) call between TD-LTE and LTE FDD based
on ST-Ericsson's multimode modem and Renesas Mobile' quad-mode chipsets during
the 2013 Mobile World Congress (MWC) in Barcelona. The success of the
demonstration further paves the way for the ultimate commercial launch of Voice
over TD-LTE.
The demonstration was accomplished on Ericsson's commercially verified LTE
TDD/FDD converged radio solution and mature IMS platform, adopting ST-Ericsson's
commercial Thor LTE modem and Renesas Mobile' quad-mode chipsets that are ready
for mass production. TD-LTE and LTE FDD enjoy a technical similarity of over
90 percent, making it possible for both networks and terminal chipsets to share
a common commercial platform.
By deploying communication services over an all-IP network, like LTE, the
opportunity opens up to evolve the voice business and launch new services like
HD voice and video calling, with telecom grade quality. At present VoLTE has
been put into commercial service with several operators, and the demand for TD-
LTE voice services is also growing, not only because the coming expanded
deployment of TD-LTE networks, but also the realization of TD-LTE voice will
allow TD-LTE operators to free up their 2G and 3G frequency bands, creating a
competitive edge at a time when spectrum resources are quickly becoming scarcer.
The demonstration also achieved HD quality TD-LTE voice service. As of January
2013, operators in 45 countries have launched HD voice over WCDMA/GSM/LTE in 61
live networks, supported by mainstream devices. HD voice over TD-LTE will ensure
superior user experience also for TD-LTE subscribers in the near future.
At its MWC debut as an exhibitor, China Mobile showcased a series of innovative
applications in an LTE TDD/FDD integrated network environment, and also
demonstrated the most complete TD-LTE end-to-end converged ecosystem so far. The
network infrastructure on site at the China Mobile booth, as well as the
integration of multi-frequency bands and multi-vendor systems and terminals, are
provided by Ericsson.
Mats H Olsson, President of Ericsson North East Asia, said: "Ericsson is honored
to support China Mobile in establishing yet another milestone in the development
of TD-LTE. The technology readiness and commercial availability of the system,
platform and devices for TD-LTE that we demonstrated here is a strong
testimonial to the maturity of a converged end-to-end TD-LTE ecosystem. 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."
Heikki Tenhunen, Senior Vice President Renesas Mobile Corporation, said;
"Renesas Mobile's long relationship with China Mobile and Ericsson brings
another joint achievement to Mobile World Congress 2013. Renesas Mobile's SP253x
and MP5232 platforms are quad-mode platforms supporting TD-LTE/LTE FDD/DC-
HSPA+/GSM. They offer commercial-grade VoLTE and high performance LTE today."
In December 2012, Ericsson assisted China Mobile Hong Kong in demonstrating the
world's first live, seamless, bi-directional LTE TDD/FDD interworking on the
converged LTE TDD/FDD network.The launch of this converged network architecture,
based on the recognized 3GPP standard, combines the power of both networks to
benefit both China Mobile Hong Kong and its subscribers and the industry as a
whole.
The convergence of TD-LTE and LTE FDD enables operators to maximize networks
based upon traffic demands and spectrum availability. Convergence provides an
operator the flexibility to deploy LTE FDD and LTE TDD throughout the network to
ensure adequate coverage, and then add additional LTE in those areas where
additional capacity is needed.
With convergence, the TDD/FDD network can be operated as a single network with
the scale needed to foster the transformation of industries like entertainment,
transportation, education, healthcare and energy.
As a firm supporter of TD-LTE, Ericsson also has a clear leadership position in
the LTE market, with more than 120 LTE/EPC contracts on six continents.
Ericsson's well-proven LTE solutions support the world's busiest networks. It
has signed contracts with nine out of the 10 highest ranked mobile operators by
revenue.
