4. Small Cells in the Enterprise
• Enterprise voice traffic predicted to grow at 12% to 2017
• Needs:
• Increased integration with IT and local voice systems
• Scalable, high quality voice and data capacity
• Challenges:
• Enhanced quality coverage for voice
• Mobile hand-off
• Demarcation between MNO and Enterprise
• Opportunities
• New MNO business models such as neutral host & cloud services
• Improved relationships with Enterprises – reduced churn

• Cost effective
• Relative ease of installation
• Localised intelligence
• Distributed processing, not unlike small cells themselves
• Option for hosting
• New cloud oriented hosting
• Enabler for future new revenues & services

6. 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
• Published December 2013
www.quortus.com

7. SCF Reference Architecture
• More functionality outside traditional MNO core
• 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

8. ‘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

9. 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

10. 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

15. Design requirements
• 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

27. Voice offload considerations
•
•
•
•
•
•
•
•
Dialplan ownership and management
User identity and short-code usage (inc. SMS)
Audio offload & SIP PBX integration
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 convergence

28. 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

29. 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
