Motivations
MNOs concepts todayTraditional connectivity & voice businessFew VAS only, trend towards OTT provided by
competitors Infrastructure and Platform sharing (MVNOs) Infrastructures, networks, and platforms …
● Pre-sized, Pre-provisioned, Pre-customized, Huge CAPEX
From traditional Mobile Network Operators…
… towards Mobile Cloud providers
MNO concepts tomorrowAdopt IaaS and PaaS for network functions
● Resource pooling, On-demand, Elastic, Pay-as-you-go
Reduce costs, move from CAPEX to OPEXNew approach to MVNO, new customers for
traditional mobile telco businessEnable for seamless integration of Mobile Network +
Computing + Storage● End-to-end platform for novel applications● Eco-system, developers, new business model

Cloud-based mobile networks: the concept
● On-demand and self-service● Elastic● Multi-tenant● Pay-as-you-go
Mobile ConnectivityDecentralized Computing
Smart Storage
offered as a single end-to-end service
Moving cloud computing beyond datacenters…
… towards the mobile end-users.

Extending the Cloud: E2E Service Orchestration
Key challenge● End-to-End Service Orchestration
– Horizontal: RANaaS+EPCaaS+CDNaaS+DSSaaS– Vertical: LBaaS, DNSaaS, MONaaS, RCBaaS

Key MCN Architectural Elements
Service Manager• Provides an external interface to the user
● Business dimension● encodes agreements
● Technical dimension● Management Service Orchestrators of a particular tenant
Service Orchestrator• Oversees the E2E orchestration of a service instance• Domain specific component• Manages service instance• 'Runtime & Management' step of the Service Lifecycle• One SO is instantiated per each tenant within the domain• SO is associated with a Service Manager• Monitors application specific metrics and scales
(SOE/SOD)
CloudController• Supports the deployment, provisioning, and disposal of
services• Gives access to atomic services• Gives access to support services• Provides possibility to configure atomic services (IaaS)

Extending the Cloud: DSSaaS
Service that enables distribution of multimedia content. Main objective:
● Re-design the Digital Signage Service (DSS) to exploit the Mobile Cloud Networking Platform. DSS Components: DSS Central Server, Content Repository, DSS Content Cache

Some Take Aways and Key Research Challenges
MCN aims at enabling mobile operators to turn into MobileCloud operators and providers● Exploit Cloud principles to move from CAPEX to OPEX● New revenue streams by enabling application developersResearch Challenges● Cloud != Telco
● Terminology, definitions, systems versus software, protocols versus APIs● Users? End-users versus application developers
● End-to-End Service Orchestration● Multi-Stakeholder domain, integration with Support Services● Alignment with TMF versus User-Centric on-demand approach by IaaS / PaaS
● Re-architecting Network Functions (e.g. RAN, EPC, IMS)● Software design, design for cloud● NFV alignment
● Telco-readiness of IaaS and PaaS● Performance, High-availability, SLAs
● SDN key enabler, many open questions● Mobile domain, Inter-DC federation, New protocols (SDN applications) for DC
networking● Interoperability and Standards

Using the Cloud: EPCaaS, IMSaaS
Novel Sotware Architectures, “designed for cloud“
● Elasticity, simplifies planning (busy hour), high-availability, migration, etc
● How much to virtualize? Data + Ctrl plane, or ctrl plane only?

Using the Cloud: RANaaS
Cloud-based RAN as a Service (RANaaS):
● Heterogeneous, virtualised and multi-tenant RAN, following cloud principles (self-service, on-demand, multi-tenancy, resource sharing, pay-as-you-go).
© 2012-2015 MCN. All rights reserved. / Page 28
Using the Cloud: RANaaS
Enabled by C-RAN, where● A BS is
– a software-based Base Band Unit (BBU) – a low-cost Remote Radio Head (RRH)– linked by an optical fronthaul
● Data centres host virtualised BBU-pools of heterogeneous Radio Access Technologies (RATs).– BBUs run and provided on cloud principle– C-RAN aims to achieve 15% CAPEX and 50% OPEX
reduction, 71% energy saving and 1/3 roll-out time and performance enhancements.
– High-performance and availability challenge for IaaS/PaaS
