� The same physical infrastructure is
used for both fixed and mobile
services.
Definition of Fixed Mobile Convergence (FMC). FMC areas identified in ScaleNet.
� One terminal could access to
services by different technology.
� Same services are offered in
fixed and mobile networks.
� The marketing and administration
personnel of both the fixed and
mobile departments are pooled
together.
Terminal convergenceNetwork convergence
Commercial convergenceService convergence
In general, FMC enables the combination of wireline and wireless/mobile networks
to provide multiple services to the customer independently of location, access
technology and device. (Source: ScaleNet)

Today's logical view
ScaleNet architecture – Network convergence.Challenges and solutions.
There is a common set of requirements and
functions like QoS, AAA, …
…but very different implementations:
� Costly, ineffective
� Mobility is major difference
� Mobility will become also a requirement in
fixed networks

Demonstrator –MeshBed.Objectives.
The aim of the testbed is to investigate carrier grade aspects of mesh networks for BWA scenarios,
e.g:
� Network architecture based on standardized equipment
� QoS support including admission control
� AAA & Security concepts
� Integration into network operator’s core networks
� Support of “Triple Play” services with comparable quality compared to fixed networks
Current mesh deployments lack carrier grade services support
� IEEE 802.11 based community networks without QoS support
� Proprietary mesh solutions based on WiMAX equipment
� Only insufficient AAA & Security support

Conclusions.
Service convergence
Control layer (IMS-3GPP/TISPAN)
� Enables Service convergence
� Standardised service control overlay for easy and
fast service creation and delivery in an IP based
environment
� Offers a set of basic control mechanisms
necessary for every service, common functions
can be reused for multiple applications., e.g.
AAA, QoS, Security, …
Network convergence
Converged Access Aggregation Network
� Enables Network convergence
� Data processing of Fixed and Mobil access
without pure tunnelling
� Uniform methods for traffic forwarding, QoS,
Mobility, AAA, …
� Universal Access node function/Interface used
for adaptation to different Access solutions
enabling flexible and scalable network utilisation
� Flat and cost efficient IP aggregation
� Access Border Controller enables interworking
with the control layer regarding QoS, Mobility,…
� Integrated FMC approach enables new attractive services bundles, increasing revenues,
retaining and winning customers, cost reductions (CAPEX and OPEX)
� Integrated Fixed/Mobile operator needs an strategy considering both Fixed and Mobile Network
ScaleNet proposes an integrated FMC network addressing Network and Service convergence
