Nokia Networks selects Radisys MRF product family for its open VoLTE/VoWiFi solution

Nokia Networks has selected Radisys' Media Resource Function (MRF) product family as the media processing foundation for its Voice over LTE (VoLTE) and Voice over Wi-Fi solution portfolio for standards-based IP Multimedia Subsystem (IMS) deployments.

Nokia will use Radisys' Virtualized MRF and high-capacity MPX-12000 Broadband MRF to provide mobile operator customers with the flexibility to choose the media processing solution that best fits their economic and technical requirements for VoLTE/VoWiFi service, according to a press release.

"Partnering with Radisys on media processing is a great example of how Nokia Networks can extend its portfolio with solutions from partner companies. In this case, the Radisys product family extends our end-to-end VoLTE solution," Michael Clever, senior vice president of Core at Nokia Networks, said in the release. "We're able to quickly provide operators with the right media processing solution for their VoLTE deployment, whether it's a virtualized solution or not.

"Radisys' virtualized MRF has been certified within Nokia Networks' telco cloud partner certification program to work with our virtualized VoLTE solution," he added. "This certification program ensures operators get the most comprehensive solutions, which meet the highest quality and security standards."

It's a typical build vs. buy type of scenario. Nokia Networks could have tried to build a solution in house, but it decided to partner with Radisys, recognizing Radisys' expertise in the very specialized area of media processing, according to Ray Adensamer, director of marketing at Radisys.

Radisys is providing both hardware and software, Adensamer told FierceWirelessTech. "They've embraced the idea of using the Radisys MRF," and they're using it in both purpose-built hardware platforms as well as virtualized MRF. "This allows Nokia to focus on its strengths," such as its integration services. "They trust us to do the IP media processing."

"Doing media processing in real time is kind of tricky, and that's why the majority of our customers right now in the field still use hardware media processing," he added. But the trend is to go to software and virtualized functions, and Radisys supports that. "We offer that choice to Nokia as well as Nokia's customers."  

Radisys has one unnamed mobile operator customer in North America that uses Nokia and Radisys in six of its data centers. Radisys also is working with companies like Mavenir and Genband; it has more than 25 VoLTE trials and deployments worldwide.

Radisys also stresses the importance of  a "OneMRF strategy"--one media processing infrastructure to address a mobile operator's entire range of IMS, WebRTC, OTT and transcoding media processing requirements. Mobile operators can deploy a Radisys MRF for one initial service, typically VoLTE, and then deploy additional applications using the same MRF as a common media processing resource.
