CUPERTINO, Calif. and TOKYO, Feb. 25, 2013  — Renesas Mobile Corporation,  announces the completion of the integration of the Voice over LTE (VoLTE) capabilities for Renesas Mobile’s communication processor and slim modem platforms for LTE smart phones. Ecrio’s FlexIMS based VoLTE Client Software is now integrated and optimised in the MP5232 and SP2532 multi-mode LTE platforms paving the way for the broad supply of VoLTE Services based on the 3GPP IP Multimedia Subsystem (IMS). Renesas Mobile combined the FlexIMS based SMS and VoLTE software with its own technology to meet the GSMA IR.92 requirements for efficient usage of LTE radio resources through techniques such as header compression and voice specific scheduling plus ensuring conversational Quality of Service (QoS) over both TD-LTE and FDD-LTE. Full inter-system handovers are also supported. Renesas Mobile will be demonstrating VoLTE capabilities on the MP5232 platform at Mobile World Congress 2013 in Barcelona on both TD-LTE and FDD-LTE systems. Further details of the embedded solution were recently published in the February 2013 edition of Mobile Europe and Renesas Mobile has written a whitepaper about VoLTE power consumption.

Based on the FlexIMS™ Architecture, Ecrio’s Mobile Communications Client Suite (MCCS) is a unique solution that incrementally enables VoLTE, Video Calling and Rich Communication Suite (RCS) services to be implemented with the flexibility to distribute functionality across processors. This architecture enables low power consumption in both LTE and 3G modes, as well as the low latencies for all the related IMS services.

“Ecrio’s unique solution has rapidly enabled VoLTE and Video Calling services across our product portfolio,” commentedHeikki Tenhunen , senior vice president Renesas Mobile. “The combined Renesas Mobile and Ecrio turn-key solution enables the OEMs to deliver a richer service experience with the highest quality multimedia communication functionality. Renesas Mobile has commercial grade VoLTE solutions available on our power and performance optimised platforms.”

“This is a proud moment in our relationship with Renesas Mobile, where our companies have executed flawlessly,” said Michel Gannage , Ecrio founder and CEO. “We are pleased to provide a ready and mature solution, leveraging our mutual industry-leading positions.”
