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

Nokia Networks will utilize Radisys’ Virtualized MRF and high-capacity MPX-12000 Broadband MRF, built on Radisys’ T-Series Network Functions Virtualization (NFV) platform, to provide its mobile operator customers for VoLTE/VoWiFi service.

Mobile operators are deploying IMS functionality as part of their LTE rollouts to enable VoLTE, as well as enhanced services including video and HD voice. An MRF is an essential element to support real-time voice and video services in an IMS architecture. Concurrently, mobile operators are developing their telco cloud deployment strategies, and need cost-effective, virtualized media processing. 

Nokia Networks will make use of a combination of Radisys’ hardware and cloud-ready software platforms to provide its mobile operator customers with a comprehensive range of deployment options for interactive HD voice and video communication services. These services are invoked by Nokia Networks’ carrier-grade and feature-rich Open Telecommunication Application Server (TAS), built according to IMS Core architecture. 

Mobile operators can deploy a Radisys MRF for one initial service, typically VoLTE, and then deploy additional applications while using the same MRF as a common media processing resource.
