Current Situation
 Many mobile operators offer a portfolio of services
to generate voice revenues
• Basic Calling (Class 5), Voicemail, RBT, IVR services, conferencing
 Each service often came with own service platform
• with built-in media processing resources
 Result is a proliferation of media resources in the
mobile network
• Different capabilities, control interfaces, platforms, and vendors
• unused media ports as demand for particular application goes
down

4. 4Radisys Corporation Confidential
Triggers for Change
 LTE leading to converged IP network for mobile industry
 VoLTE driving need for IMS
• IMS provides opportunity for Common MRF strategy
 Video services
• Existing media processing resources often don’t support video
 Cloud deployment
• Increasing requirements for media processing in Cloud
 OTT and carrier networks are blending/overlapping
• Internet users getting telecom services
• Telecom service providers reaching out to Internet users
Increasing requirements for reusable,
efficient media processing infrastructure

The Foundation for many VoLTE and Video Services
Question?
What do all these
VoLTE and IMS services
have in common?
Answer:
They all share an
underlying need for
real-time IP-based
voice and video
RTP media processing
One Common MRF,
Shared amongst all IMS services.

Summary - Common MRF Strategy
 VoLTE and IMS
• Deploying VoLTE or IMS requires MRF that delivers features and
services across access networks and applications.
 As you deploy other real-time LTE communication
services…
• Business objective is efficient and scalable use of media resources
• Video, Conferencing, WebRTC, IVR services, plus many more…
– all can and should use same Common MRF
The more services that share the MRF,
the bigger the benefits

Synopsis – Common MRF
 Consolidating / Pooling Network Media Resources for Re-
usability
 Separation of Application Logic and Control Plane from Media
Plane
 Centralized and Distributed Deployment Architectures
 Benefits
• Improved Economics via Re-use of Media Resources Across
Applications
• Reduces Operational Complexity and Network Management

28. 28Radisys Corporation Confidential
Summary – MRB Strategy
 Current Situation
• MRF selection logic and Load Balancing often needs to be
Implemented into each Application.
• As number of applications and MRF nodes grows, Selective LB
logic becomes unwieldy to manage, while impacting MRF utilization
 MRB
• Media Resource Broker (MRB) is an abstraction layer
between IMS applications and MRF resources.
• MRB dynamically manages state/load of each underlying MRF, as
well as capabilities of each MRF.
• Applications send All media processing request to one entity - the
MRB - simplifying the Application Logic
• Based on load, capability required, and geo location (amongst other
factors), the MRB then selects and forwards the AS media
processing request to the selected MRF
