TRENDS IN TELECOM ARENA
Telecom companies try to monetize their infrastructure investments and to improve customers’ experience
Mobile network owners are scrambling to stay ahead of data demand
But
Revenues are stagnating
Mobile data traffic demands increases exponentially
OT T players – video, audio, and other services, piggyback free on telecom systems

WHAT OPERATORS DO?
They are scrambling to stay ahead of data
demand
Implement carrier aggregation, made possible in
the 3GPP standards
Employing network densification
and that means more environmental, size, cost,
and power considerations across the network.
Re-farm spectrum as fast as they can

H2020 5G-PPP SESAME PROJECT
Placement of network intelligence and applications in
the network edge through NFV and Edge Cloud Computing.
Consolidation of multi-tenancy in communications
infrastructures. Allow several operators/service providers to engage in new sharing models of both
access capacity and edge computing capabilities.
Small Cells’ evolution is already mainstream in 4G, but expected to deliver its full potential in the challenging
dense deployment 5G scenarios.

OVERVIEW
SESAME proposes the Cloud-Enabled Small Cell (CESC) concept
CESC: a single device that
is able to accommodate multiple operators/’tenants’ in offering network capacity resources into logically isolated ‘slices’
provides a virtualized execution infrastructure, i.e. a Light DC at the edge of the network
be offered on-demand to CSPs/VNOs
Infocom World 2016 _ Athens, Greece, Nov.02, 2016 SESAME-based Special Session
AREAS IN SCOPE
Small Cells:
Radio Architecture: MOCN
Deploy virtualized infrastructure through HW acceleration (non x86 processors)
New network orchestration perspectives in the 5G framework
Network Function Virtualisation for Multi-tenancy & Network Management
Self-x Features: self-organizing, self-optimizing, self-healing, etc.
Cloud technologies: execute novel applications and services inside the access network infrastructure

– A Small Cell network capable to
support more than one network
operator is envisaged.
– 3GPP specifications have already
added some support for Radio
Access Network (RAN) sharing and
Multi-Operator Core Network
(MOCN), where the shared RAN is
directly connected to each of the
multiple operator’s core networks,
has been identified as the exclusive
enabler for multitenancy features in
SESAME platform.
– The infrastructure consists of a
number of Small Cells and the
corresponding SC network functions
such as gateways and
management systems.

CLOUD ENABLED SMALL CELL (CESC)
ATTRIBUTES
The CESC exposes different views of the network resources: per-tenant small cell view, and physical small cell substrate,
The physical small cell part is managed by the SCNO, and decouples the management of the virtual small cells from the platform itself.
Rather than providing multiple S1 (or Iu-h interface) connections from the physical small cell to different operators’ EPC network elements such as MME and SGW, such fan-out is done at the micro server.
The CESC is further the termination of multiple S1 interfaces connecting the CESC to multiple MME/SGW entities as in S1-Flex.
It offers the possibility to offload traffic from congested macrocells, allowing for a variety of value-added services

KEY GOALS
Development and demonstration of innovative architecture, capable of
providing Small Cell coverage to multiple operators, “as-a-Service”.
Logical partitioning of localized Small Cell network to multiple isolated
slices, as well as their provision to several tenants.
In addition to virtualizing and partitioning Small Cell capacity, SESAME
supports enhanced multi-tenant edge cloud services by enriching Small
Cells with “micro servers”.
Apart from benefits offered to existing market players, the SESAME
approach allows new stakeholders to dynamically enter the network value
chain
Infocom World 2016 _ Athens, Greece, Nov.02, 2016 SESAME-based Special Session
INNOVATION POTENTIAL OF SESAME
SESAME creates a standardized, open environment allowing efficient & seamless third-party application integration across multi- vendor platforms
SESAME envisions network neutrality, multi-tenancy whereas is not practical to densify existing networks, and places where dense concentrations of users place extreme demand.
SESAME delivers several computational, storage and networking resources via VNFs empowered by HW accelerators. High performance required at lower costs and with lower power consumption.
SESAME Orchestrator will build services (e.g., service function chaining, billing, or even SLA management) over multiple clusters of virtualised small cells.
