Beijing,
June
6,2007 -
Beijing T3G technology Co., Ltd. (T3G) and NXP Semiconductors
(NXP), the independent company founded by Philips, today made
a joint announcement of the world¡¯s first voice automatic
handover of multi-mode TD-SCDMA and GSM/GPRS/EDGE in a
handset. This breakthrough handset enables seamless usage for
end-users by providing bi-directional on-the-fly automatic
handover between TD-SCDMA and GSM networks. NXP and T3G
powered multi-mode handsets can automatically scan for
available networks and smoothly switch to between TD-SCDMA and
GSM networks ensuring the best quality of service and high
user satisfaction.
The automatic handover feature has been achieved and validated
successfully on T3G¡¯s TD-SCDMA/GSM/GPRS/EDGE dual mode handset
reference design platform in multiple network environments
built by all major Chinese infrastructure vendors including
Datang Mobile, ZTE and TD-Tech. Seamless automatic handover of
voice calls between 3G TD-SCDMA R4 wireless network and 2.5G
GSM/GPRS/EDGE mobile networks are supported.
Even while a call is being placed, a TD-SCDMA/GSM phone
equipped with the automatic handover feature moving out of TD-SCDMA
network coverage will automatically switch the user onto the
existing GSM network, without any adverse effects such as call
drop. Because the network selection and transition are done by
the phone automatically, TD-SCDMA subscribers will not have to
make any manual selection of service, and thus will be able to
enjoy a true ¡°seamless¡± multi-mode experience.
Currently, TD-SCDMA networks are being rolled out in 10
Chinese cities including 6 host cities of Beijing Olympics by
China Mobile and other Chinese operators. Automatic handover
TD-SCDMA phones not only facilitate the provision of advanced
TD-SCDMA 3G services to interested audiences at these Olympic
host cities, but also allow the continued use of existing 2.5G
network infrastructure.
Mr. Daijun Zhang, CTO of T3G said, ¡°With the realization of
TD-SCDMA and GSM/GPRS/EDGE automatic handover feature thus
ensuring great backward compatibility with 2.5G networks, the
most challenging technological hurdle facing the TD-SCDMA
handsets at the initial commercial stage has been cleared. The
addition of the TD-SCDMA/GSM/GPRS/EDGE automatic handover
feature to the T3G reference design platform will give our
handset maker customers an advantage in creating a rich
variety of competitive TD-SCDMA mobile handsets that meet the
demands of the China market.¡±
Mr. Dan Rabinovitsj, Senior Vice President for Cellular
Systems of NXP said, ¡°NXP has been cooperating closely with
T3G and has made substantial investment in the China 3G
standard from the very start. By leveraging NXP¡¯s EDGE
leadership and system maturity and T3G¡¯s cutting-edge R&D
capabilities, NXP and T3G achieved the first TD-SCDMA/GSM/GPRS/EDGE
automatic handover. Working closely with local handset
manufacturers, NXP and T3G have contributed substantially to
creating a local ecosystem driving towards wide deployment of
next generation 3G services in China. The industry¡¯s first
achievement of automatic handover is testimony of our
preemptive strategy to gain a leading position in the Chinese
market.¡±
This automatic handover is enabled by the Nexperia cellular
system solution T3G 7208 GSM/GPRS/EDGE/TD-SCDMA reference
design. Based on NXP's leading EDGE system solution, the
design full meets China major operators¡¯ plan to upgrade
theirs 2G network to EDGE to offer fallback of data services.
By keeping the same baseband, 2G chipset and application
software interfaces for both standards, the reference design
enables handset manufactures to maximize their R&D investment
in both TD-SCDMA and WCDMA.
T3G and NXP have been providing comprehensive technical
support and key technology and products to its customers in
order to promote the speedy ramp-up of the TD-SCDMA handset
market.
