he Radisys MediaEngine™ Virtualized MRF (vMRF) is a media processing powerhouse for a wide range of revenue-generating interactive HD audio and HD video services. The software-only solution is highly optimized to deliver exceptional performance in virtualized and cloud environments. With support for 3GPP IR.92, IR.94 and WebRTC, the vMRF is ideally suited for communication service providers deploying VoLTE, IMS and over-the-top (OTT) services.
The 3rd Generation Partnership Project (3GPP) calls media server as a Media Resource
Function (MRF). Web and Universal Control (UC) developers call it a media server. The
conferencing industry calls it a conference bridge or a multipoint control unit (MCU).
Regardless of the name or the underlying IP network infrastructure deployed, Radisys
MediaEngine is the leading solution for enabling rich media applications using MRF. The
Radisys MediaEngine portfolio delivers the solution on MRF, which is a key component in IP
Multimedia Subsystem (IMS) architecture for Long Term Evolution (LTE) technology.
Radisys is the leading supplier of IP MRFs for Communication Service Providers (CSPs). Radisys
has created the next generation of MediaEngine product family combining the best of the
Internet and telecommunication world. Our award-winning family of IP media servers and
IMS MRF allow service providers to reduce service delivery costs and increase revenues
through new approaches to network- based services. The Radisys MediaEngine product family
consists of the highly reliable and scalable virtualized MRF (vMRF).
For CSPs, VoLTE moves voice processing to the LTE network, freeing up the 2G and 3G spectrum and reusing the spectrum to expand the LTE network footprint and increase performance. CSPs can deliver connections with guaranteed QoS and end-to-end low latency due to native support for voice and video on their LTE network.
The Radisys MediaEngine portfolio delivers the MRF, which is a key component in an IMS architecture for LTE. MRF enables mobile operators to rapidly deploy VoLTE not only by supporting essential functions (such as tones, announcements, and three-way calling) but also by offering a common media processing platform for all of your media processing needs including transcoding, video services, and margin-rich value added services. The vMRF are optimized for VoLTE offering support for IR.92 and IR.94—the standards for voice and video over LTE. For IR.94, vMRF particularly support those features that maintain call quality amidst the bandwidth fluctuations and packet loss found in mobile networks.
vMRF in the IMS/VoLTE network
CSPs that deploy a decomposed network architecture gain significant advantages over the competition. CSPs can reduce costs and network complexity by decoupling media resources from the applications that use media resources and by deploying a shared MRF as defined in the IMS architecture.
Many services in the network utilize media processing; individual applications generally experience peaks and valleys. This means that in an IMS architecture, more applications can use fewer media resources. Administrators no longer need to learn multiple ways to install, manage, and administer the elements that perform the same role. MediaEngine is the leading choice of OneMRF deployments by service providers. The
application provides a number of standards-based control interfaces for broad application server interoperability and delivers a rich audio and video feature set to serve hundreds of media application use cases. Radisys boasts deployments around the world in the network infrastructures and platforms of leading IMS and WebRTC vendors.
