Renesas Mobile and Ericsson Announce First Inter-mode VoLTE Call Between TD-LTE and FDD-LTE Commercial Networks and Devices
TOKYO & STOCKHOLM --(Business Wire)--
Mobile Corporation, an innovative supplier of advanced cellular
semiconductor solutions and platforms and Ericsson (News - Alert), the world's leading
provider of communications technology and services, today announced a
demonstration of the world's first inter-mode Voice Over LTE (VoLTE)
call using pre-commercial devices from a leading manufacturer. This will
take place at China Mobile's booth 5I120 at Mobile World Congress (News - Alert) 2013
The next step in the evolution of VoLTE, this demonstration, held in
conjunction with leading Chinese operator China Mobile (News - Alert), illustrates
Renesas Mobile and Ericsson's commitment to ensure the seamless
operation of VoLTE across different networks. This converged TD-LTE and
FDD-LTE (News - Alert) approach enables operators to balance the load between each LTE
network. It also permits international roaming independent of consumers'
device capabilities as terminals are currently TD or FDD only.
Ericsson's convergent IP Media Subsystem (IMS) core ensures that VoLTE
services are consistent, regardless of the underlying radio network (FDD
or TD), to ensure a more consistent user experience. The Renesas Mobile
multi-mode LTE SP2532, MP5232 and MP6530 platforms all have a
convergence compliant IMS client supporting both networks. This also
means that Renesas Mobile has the capability to support VoLTE on 3rd
party application processors when used in conjunction with the SP2532.
"Renesas Mobile and Ericsson have been collaborting for many years and
this is another example of that relationship bringing direct benefits to
our customers," said Heikki Tenhunen, senior vice president Renesas
Mobile Corporation. He continued "VoLTE is a key enabler for supporting
voice over LTE and we are ensuring that this technology is validated and
proven with leading infrastructure vendors."
This advance in VoLTE will be used by operators who have both FDD and
TD-LTE assets, in either the same, or different countries. Renesas
Mobile and Ericsson are currently in discussions with customers who have
both types of network in use.
