Media Processing Strategies for VoLTE & Interactive Voice Services

  1. 1. 1Radisys Corporation Confidential Welcome to today’s Webinar… Media Processing Strategies for VoLTE and Interactive Video Services Webinar October 9, 2013 11am ET, 4pm London
  2. 2. 2Radisys Corporation Confidential Topics  Proliferation of Media Processing  Triggers for Change  Common MRF Strategy • Decomposition and Media Processing Reuse • One MRF for Many Services • Media Processing Deployment Scenarios  Media Resource Broker (MRB) • Efficient use of Media Resources  Benefits  Case Studies  Summary Speakers Ray Adensamer Senior Manager, Product Marketing Radisys Adnan Saleem Chief Architect Radisys
  3. 3. 3Radisys Corporation Confidential 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. 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
  5. 5. 5Radisys Corporation Confidential Radisys Common MRF The Foundation for many VoLTE and Video Services Question? What do all these VoLTE and IMS services have in common?
  6. 6. 6Radisys Corporation Confidential 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.
  7. 7. 7Radisys Corporation Confidential Topics  Proliferation of Media Processing  Triggers for Change  Common MRF Strategy • Decomposition and Media Processing Reuse • One MRF for Many Services • Media Processing Deployment Scenarios  Media Resource Broker (MRB) • Efficient use of Media Resources  Benefits  Case Studies  Summary Speakers Adnan Saleem Chief Architect Radisys
  8. 8. 8Radisys Corporation Confidential 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

  28. 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
