  10. 10. Alberto Diez – 2016 The role of policy control today • Shift from QoS to VoLTE • Competition with Charging for Usage Monitoring / FUP upsell of data plans • Overcoming DPI and circumventing Net-neutrality with OTT & zero-rating VoLTE Data Plans Zero-Rating OTT
  11. 11. Alberto Diez – 2016 VoLTE • VoLTE made PCRF mandatory when it was not • VoWiFi and ViLTE not as relevant • What is needed for VoLTE? – Rx interface – Emergency support – NetLoc – Basic Events – MPS – SIP-Forking No Need for: - user profiles - usage monitoring - DPIs - S9
  12. 12. Alberto Diez – 2016 Usage Monitoring and Data Plans • Disputed feature with OCS • In favor of PCRF are – Required for postpaid too – Personalization / Subscriber profiles – Policy and QoS effect – Application / Context awareness – More flexible rules engine • Against it – Rating / Bill Shock prevention
  13. 13. Alberto Diez – 2016 OTT & Net-neutrality • Zero-rating as killer application where its allowed • Net-neutrality permits – Emergency – VoLTE and operator services prioritization – Congestion control
  14. 14. Alberto Diez – 2016 Value for the end user • Classical – QoS & dedicated bearer but user cares about QoE – Emergency calls but PCC is optional • Innovative – Personalization – Data plans upsell (e.g. roaming, video)
  15. 15. Alberto Diez – 2016 Value for the service provider • Gain agility with a common point for control and provisioning of a service proposition – Usage Caps – QoS & policies – Traffic steering • Congestion control
  16. 16. Alberto Diez - alberto@mobileplots.com 3GPP
  17. 17. Alberto Diez – 2016 Traffic Detection Function • ADC rules • Redirection • Unsolicited ADC rules operation
  18. 18. Alberto Diez – 2016 Interaction with OCS • Sy interface • Spending Limits as input for policy decision Integration with BBF • S15 and S9a interface • Irrelevant
  19. 19. Alberto Diez – 2016 Congestion Control • RCAF and Np interface • RUCI info per IMSI or APN and ECGI, SAI eNodeB-Id.. • PCRF to consider this information for new policy decision • Possibility to activate it by IMSI (restrictions) • Mobility to new RCAF area an issue
  20. 20. Alberto Diez – 2016 Traffic Steering • TSSF and St • Selecting between different (S)Gi-LAN • Can be done by the PCEF or TDF instead • Traffic description and reference to traffic steering policy
  21. 21. Alberto Diez – 2016 APIs & Network Capabilities • Nt interface to SCEF for exposure of network capabilities (i.e. OMA or others) – Background data transfer window reservation “transfer policy” • Rest-Rx and Protocol Converter
  22. 22. Alberto Diez – 2016 NBIFOM • Related to Multi-access IPCAN sessions • UE initiated and Network Initiated • PCRF is not mandatory • Routing Rules authorization (UE) and selection (Network)
  23. 23. Alberto Diez - alberto@mobileplots.com NFV/SDN
  24. 24. Alberto Diez – 2016 NFV/SDN promise • Flexibility • Agility • Time-To-Market • Reduce OPEX
  25. 25. Alberto Diez – 2016 NFV Management & Orchestration • MANO does have service models and interacts with BSS/OSS but – Reserves resources – Instantiate and deploy Functions – Provisions Services – Configure Services MANO Telco Network BSS Onboard new enterprise With these policies 1. Reserve virtual resources 2. Instantiate new elements (PDN-Gw, PCRF) 3. Configure networking (SDN) 4. Configure new elements 6. Configure existing elements (DRA, SGw) 5. Provision policies

  30. 30. Alberto Diez – 2016 OpenDayLight and its projects • SDN Controllers use models (described with YANG) for network elements and for the information send to them • Projects: – ASPEN – Real time Media REST NBI. Intent based. Dynamic QoS reservation for Lync and Webex. – Boulder – Intent framework for any controller – Service Function Chaining – Group Based Policy – Network Intent Composition

  32. 32. Alberto Diez - alberto@mobileplots.com IoT
  33. 33. Alberto Diez – 2016 Use of policy in M2M • Known operators cases – Usage monitoring and group counters to control M2M expenditure – Selecting 2G, 3G or LTE speed
  34. 34. Alberto Diez – 2016 Does IoT need policy? • Wearables • Connected House • Connected Car • Smart Cities • eHealth Background application data transfer windows is interesting because of mass rollout of updates etc. But why does the PCRF predict? Couldn’t someone else do it?
  35. 35. Alberto Diez – 2016 Industry 4.0 and policy • Going beyond sensors and actuators • Low-latency industrial applications • High bandwidth critical data

  40. 40. Alberto Diez - alberto@mobileplots.com Telecom trends* *(selected from Gartner)
  41. 41. Alberto Diez – 2016 Big Data • PCRF can be both source or sink of big data • Source: PCRF receives a lot of information from the network, applications, user • Sink: PCRF can learn from Big Data to optimize policies and achieve network efficiency
  42. 42. Alberto Diez – 2016 Machine Learning • The PCRF could automatically learn from the networks new policies • Congestion avoidance • Optimizations • Combined with Big Data • Manual approval?
  43. 43. Alberto Diez – 2016 Natural Languages noun verb adjective • Could policies be expressed in natural language? • Combined with Intent • Would it reduce complexity and OPEX?
  44. 44. Alberto Diez – 2016 WebRTC / Contextual Services • Can policy add to context? • Can policy grant QoE in WebRTC services?
  45. 45. Alberto Diez – 2016 Open APIs / Open Data • To few attempts to expose policy as part of network capabilities • APIs e.g. OMA One • Data can be exported for analytics
  46. 46. Alberto Diez – 2016 Open Source • Fundamental in NFV/SDN – OSM group in ETSI – OPNFV – OpenDayLight and ONOS • If policy is part of SDN Control then Open Source is part of policy
  47. 47. Alberto Diez - alberto@mobileplots.com Future of policy control
  48. 48. Alberto Diez – 2016 The role of policy control • QoS might be done by the SDN Controllers via API • Data Plans might be a charging feature OSS/BSS • Zero-rating and OTT partnership might be an SDN Controller exposed API QoS Data Plans Zero-Rating OTT
  49. 49. Alberto Diez – 2016 Value for the end user • Personalization combining Real-Time and Subscriber Data awareness
  50. 50. Alberto Diez – 2016 Value for the service provider • Not from 3GPP • Does it help to reduce OPEX? • Does it make the network simpler? • Does it contribute to quick deployment of services? • Does it provide flexibility?
  51. 51. Alberto Diez – 2016 Thank you! http://mobileplots.com Takeaways 3GPP Core Network losing relevance PCRF needs to cooperate with SDN Controller and provide value by itself Slice-PCRF and use-case specific PCRF Upcoming Trends Simplification of core network Automated and intelligent policy
