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.com3 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 stakeholderswww.quortus.com4 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 isnt natural! SCF067 Enterprise Small Cell Network Architectures Document available from www.scf.iowww.quortus.com5 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.com6 7. Where is the network edge? 1. The physical edge Voice Packet DataHNB GWMNO Core network MNO boundary is protected Edge is physical edge, on or colocated with the radio Grow ecosystem Convergence at the edge www.quortus.comNetwork edgeEdge SmartsConsumer / Enterprise space7 8. Where is the network edge? Network edge2. The logical edge The cloudVoice Packet DataHNB GWMNO Core network MNO boundary is protected 3rd party SPs can add value No impact on physical edge Legal intercept compatible www.quortus.comEdge SmartsHosted PBX Hosting SP Consumer / Enterprise space8 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-ablewww.quortus.com9 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, SOHOwww.quortus.comEnterprise 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.com11 12. Enterprise Architecture Concepts 1. 3G Iuh aggregation 2.
