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


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

Radisys Common MRF 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

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

Summary


Case Studies IMS Applications, VoLTE, MMtel, RCS

Large European Incumbent Service Provider

• Started with IMS Pilot Project

• Added Conferencing Application – sharing same MRF

• Currently integrating CSCF to share same MRF

• Expanding from wireline to mobile VoLTE deployment

Rapidly Growing VoLTE IMS Solution Vendor

• Common MRF for CSCF and MMTel Services

• VoLTE

• RCS


Case Study NGN Value Added Services

Large TEM (Asia) • TEM performed “buy vs build” analysis for MRF in their NGN and

IMS architecture.

• Early MRF deployments supported announcements, DTMF, and IVR

for Softswitch (Class 5 feature set)

• Updated voicemail AS to use Radisys MRF

• Same MRF used for RBT deployments, and

trials for video RBT and conferencing

• RESULT: Radisys MRF has been deployed in multiple countries

supporting multiple applications.


Case Study Border GW, UC, Conferencing

Large TEM (North America)

• TEM performed “buy vs build” analysis to replace multiple

Media Processing Platforms with Radisys MRF

• Common MRF for

– CSCF / Border Gateway

– UC Application Server

– Conferencing Application Server

– Transcoding in WebRTC gateways

• Virtualized MRF for Cloud Deployment

Summary


Summary

Common MRF

• Operator strategy to deploy with fewer MRF vendors in their IMS rollouts

• Application requirement to reuse common MRF, rather than adding different

MRF resources with each new application.

• Benefits

– Reduces operational complexity, improves MRF reuse

MRB

• Layer of abstraction between IMS applications and MRF resource pools

• Benefits:

– Simply AS design by moving MRF selection and load balancing into MRB

– Cost savings through resource utilization in geos outside peak periods

Radisys Value Proposition

• Radisys is #1 global MRF supplier for IMS industry.
