Evolving Architectures for Small Cells in the Enterprise

  1. 1. Evolving architectures for Small Cells in the Enterprise Small Cell World Americas 2013 Andy Odgers, CEO www.quortus.com
  2. 2. Contents 1. 2. 3. 4. 5. Network edge intelligence SCF Release 2 for Enterprise Enterprise architectural concepts Service integration Where Quortus fits in – our portfolio www.quortus.com 2
  3. 3. Quortus – The company • Headquartered near London, UK • Software technology company • Sub-system oriented • Core network functionality – at the network edge • Technology branded EdgeCentrix • Radio agnostic • Target markets: Enterprise, public-safety, tactical • Channels: System integrators, solution providers • Small Cell Forum award winner 2012 • ‘Best service or application for small cells’ www.quortus.com 3
  4. 4. Small Cell Forum Release 2 • • • • Comprehensive guide to Enterprise deployment Set of 25 documents, including a reference architecture Helps unlock Enterprise opportunity Follows-on from successful Residential Release • New challenges, increased complexity, more stakeholders www.quortus.com 4
  5. 5. SCF Reference Architecture • More functionality outside traditional MNO domain • Careful and considered migration towards network edge • Two new main architectural functions • Enterprise Small Cell Concentrator (ESCC) • Enterprise Small Cell Gateway (ESCG) • Voice is main Enterprise driver – Still the ‘Killer App’ • Data isn’t ‘natural’! • ‘SCF067 Enterprise Small Cell Network Architectures’ • Document available from www.scf.io www.quortus.com 5
  6. 6. The migration to the edge • Traditional network core: • Defined by ‘size and weight’ as much as functionality • Scaled by making big box in the middle even bigger • Compare with Internet-style distributed model: • Scaled by addition of intelligent endpoints • Relatively minor changes to the ‘core’ (ie to capacity) • Need to recognised balance of core/cloud vs edge • Powerful drivers for ‘neutral host’ SP layer www.quortus.com 6
  7. 7. Where is the network edge? 1. The physical edge Voice Packet Data HNB GW MNO Core network • MNO boundary is protected • Edge is physical edge, on or colocated with the radio • Grow ecosystem • Convergence at the edge www.quortus.com Network edge Edge ‘Smarts’ Consumer / Enterprise space 7
  8. 8. Where is the network edge? Network edge 2. The logical edge The ‘cloud’ Voice Packet Data HNB GW MNO Core network • • • • MNO boundary is protected 3rd party SPs can add value No impact on ‘physical’ edge Legal intercept compatible www.quortus.com Edge ‘Smarts’ Hosted PBX Hosting SP Consumer / Enterprise space 8
  9. 9. On-the-edge benefits • • • • • Offload – allows capacity scaling Aggregation – allows coverage scaling Service convergence were services used/consumed Allows better leverage of non-cellular ecosystems Drives innovation, and communities – ‘not just a phone number’ • Disruption kept at edge, (rapid) innovation at edge • More (perceived?!) end-user control – monetise-able www.quortus.com 9
  10. 10. Inputs: ‘Enterprise’ characteristics Residential Single cell (single location) Low user density Low traffic load No mobility Limited local services User expectation same as macro Limited scope to monetise Examples: Home, SOHO www.quortus.com Enterprise Multi-cell (multi-location?) Medium user density Medium traffic load Mobility, local and out to macro High level of local service interop Higher level of user expectation Potential sources of new revenue Examples: SMEs, corporate buildings Shopping malls 10
  11. 11. Inputs: Operator feedback • Need for well defined demarcation point between MNO and Enterprise IT for: • System management, IP security and IP engineering • Service hand-off, any sensitive signalling • • • • • • No ‘hijacking’ of traffic! Quick to scale Maintain network security integrity (eg. IPSec tunnels) Billing integrity. Can monetise solution. Strong firewalling to prevent bridging of IP networks Honour legal intercept & other regulatory obligations www.quortus.com 11
  12. 12. Enterprise Architecture Concepts 1. 3G Iuh aggregation 2. Mobility offload 3. Voice and data offload 4. Local service interaction www.quortus.com 12
  13. 13. Enterprise Architecture Concepts 1. 3G Iuh aggregation 2. Mobility offload 3. Voice and data offload 4. Local service interaction www.quortus.com 13
  14. 14. Iuh Aggregation – Premise based • Aggregation function within ESCC on Enterprise premise • Effective coverage multiplier • Saves on core network capex MNO Enterprise • Not necessarily linear • Creates ‘fan-out’ to achieve scale Mobile operator core HNB Gateway Security Gateway Internet Iuh Enterprise Concentrator Iuh www.quortus.com Iuh 14
  15. 15. Iuh Aggregation – Hosted • Aggregation function within hosted ESCC • Iuh backhauled fully through SeGW • Opportunity for 3rd party SCaaS providers? Mobile operator core HNB Gateway Iuh Enterprise Concentrator Security Gateway MNO Enterprise Internet Iuh www.quortus.com Iuh 15
  16. 16. Enterprise Architecture Concepts 1. 3G Iuh aggregation 2. Mobility offload 3. Voice and data offload 4. Local service interaction www.quortus.com 16
  17. 17. Mobility offload 1 PSTN user • Takes burden of signalling away Mobile operator MSC HNB Gateway from real core (FGW & MSC/SGSN) Iuh • Call continuity during hand-out, anchor point MNO Internet Enterprise • Can’t monetise handover Iuh • Aim: Data/voice session continuity Mobility Control during hand-out to macro ESCC Iuh Cell A www.quortus.com Cell B 17
  18. 18. Mobility offload 2 PSTN user • Mobility anchor point within Enterprise • No handover signalling through HNB GW or MNO MSC • Signalling between on-premise cells only • Faster, higher quality handovers HNB Gateway MNO Enterprise Internet Mobility Control Handover signaling Cell A www.quortus.com Mobile operator MSC Cell B 18
  19. 19. Mobility offload 3 PSTN user • Handset now on Cell B, no HNB Gateway macro signalling occurred • More complex scenarios cover hand-out to the macro network Mobile operator MSC MNO Enterprise Internet Mobility Control Cell A www.quortus.com Cell B 19
  20. 20. Enterprise Architecture Concepts 1. 3G Iuh aggregation 2. Mobility offload 3. Voice and data offload 4. Service interaction www.quortus.com 20
  21. 21. Voice offload - Concept • • • • • • Mobile operator core Authentication still through macro HNB Gateway Bring Your Own Device BYOD Iuh SIP register – like an extension MNO No downloaded clients Internet Enterprise Leverages IP-PBX features SIP Local Offload LTE: Local P-CSCF SIPUA IP-PBX ESCG Control Iuh x2001 www.quortus.com x2020 21
  22. 22. Voice offload – Hosted model • Allow more integration with IP-PBX – HNB Gateway MNO may offer as package • Opportunity for neutral host? Hosted IP-PBX Mobile operator core Iuh SIP MNO Enterprise SIPUA ESCG Offload Control Internet Iuh www.quortus.com 22
  23. 23. Voice offload considerations • • • • • • • • • Dialplan ownership and management User identity and short-code usage (inc. SMS) Audio offload & SIP PBX integration Emergency call handling (even with WAN failure?) Pure local users (‘DECT’ replacement) Legal intercept (operator obligations) Macro hand-in/hand-out management Local P-CSCF anchoring for IMS/LTE calls Class 5 feature conflicts and convergence www.quortus.com 23
  24. 24. Data offload - Concept Mobile operator core • Leverages LIPA Local-GW concept • Access local LAN/Intranet from UE • Firewall for open access APs, avoid network bridging • Offload by specific APN • Transparent to VoIMS HNB Gateway Iuh MNO Enterprise Enterprise LAN Gi Internet ESCG L-GW Offload Control Iuh www.quortus.com 24
  25. 25. Enterprise service integration • Unified Communications can now include cellular access (BYOD) • Key to leverage 3rd party voice & IT app eco-system • Alignment with other evolving standards, eg VINE • Location reporting (potentially fine grained) • Analytics (eg shopping mall footfall) • Community oriented • Branded services (3rd party SP opportunities) • New APIs being introduced specific to small-cells www.quortus.com 25
  26. 26. Quortus product launch - SCA 2013 Two software products, implementing the Small Cell Forum Release 2 reference architecture for Enterprise. ECX Enterprise Concentrator ECX Enterprise Gateway • Built upon award-winning Quortus EdgeCentrix technology • Designed for hosted and on-premise deployment • Sub-system, supplied into solution providers www.quortus.com 26
