Renesas Mobile and Ericsson Announce First Inter-mode VoLTE Call Between TD-LTE and FDD-LTE Commercial Networks And Devices

Supports drive to converged networks by allowing roaming between TD-LTE and FDD-LTE

26 Feb 2013

TOKYO, Japan and STOCKHOLM, Sweden, 26th February, 2013 — Renesas Mobile Corporation, an innovative supplier of advanced cellular semiconductor solutions and platforms and Ericsson, 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 2013 in Barcelona.

 

The next step in the evolution of VoLTE, this demonstration, held in conjunction with leading Chinese operator China Mobile, illustrates Renesas Mobile and Ericsson's commitment to ensure the seamless operation of VoLTE across different networks. This converged TD-LTE and FDD-LTE 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 collaborating 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.
