Evolving Architectures for Small Cells in the Enterprise
- 1. Evolving architectures for Small Cells in the Enterprise Small Cell World Americas 2013 Andy Odgers, CEO www.quortus.com
- 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. Enterprise Architecture Concepts 1. 3G Iuh aggregation 2. Mobility offload 3. Voice and data offload 4. Local service interaction www.quortus.com 12
- 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. 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. 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. Enterprise Architecture Concepts 1. 3G Iuh aggregation 2. Mobility offload 3. Voice and data offload 4. Local service interaction www.quortus.com 16
- 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. 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. 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. Enterprise Architecture Concepts 1. 3G Iuh aggregation 2. Mobility offload 3. Voice and data offload 4. Service interaction www.quortus.com 20
- 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. 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. 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. 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. 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. 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
