Objective FMC
•
•
•
•
•
Seamless services from the user perspective across the heterogeneous
fixed (i.e., PSTN, ISDN, PSDN, WAN/LAN/CATV, etc) and mobile
networks should be guaranteed in FMC.
Seamless service provisioning from the operator perspective across the
heterogeneous fixed (i.e., PSTN, ISDN, PSDN, WAN/LAN/CATV, etc) and
mobile networks should be guaranteed in FMC.
Generalized Mobility supporting should be supported in FMC (i.e.,
terminal mobility, user mobility and session mobility). For a given scenario,
different level mobility may be needed.
Ubiquity of service availability. The end-users can enjoy virtually any
application, from any location, on any device. All the services/application
can be used by an end-user through any kind of access technology if that
service has been subscribed and is supported by his/her terminal device.
The service/application availability is only dependent on the user's
subscription and capability of the terminals.
Supporting multiple user identities and authentication/authorization
mechanisms.

So why don’t I give all my employees a mobile phone and
be done with it?
•
Cost - mobile minutes are more expensive than landline minutes
•
Stranded Assets – I’ve invested in IP PBXs and IP desk phones
and do not want those investments to go to waste
•
Lack of Integration - My deskbound employees don’t need a
mobile phone, but I don’t want two islands of users (desk and
mobile)
Fixed Mobile Convergence – the seamless integration of mobility into
business’s fixed infrastructure - addresses each of these concerns
FMC addresses “going mobile”
•
Cost - mobile minutes are more expensive than landline minutes
A key component of FMC is cost efficiency – many implementations
can keep calls “on-net”, saving mobile minutes
•
Stranded Assets – I’ve invested in IP PBXs and IP desk phones
and do not want those investments to go to waste
FMC is designed to work in tandem with existing infrastructure, in
many cases making it more useful
•
Lack of Integration - My deskbound employees don’t need a
mobile phone, but I don’t want two islands of users
The beauty of FMC is that deskbound, semi-mobile, and mobile
employees share the same feature capability and environment
Levels of FMC
 Network Convergence: Fixed/mobile
networks physically share transportation
infrastructure. (access N/w & core N/w)
 Commercial Convergence: Resources of
Fixed/mobile networks are pooled.
 Service Convergence: Seamless delivery
of Fixed/mobile telephony and supporting
services is achieved. (voice, IM, SMS)
 Terminal Convergence:
FMC + Access Technologies:
Digital subscriber line (DSL):
24 Mbps downstream
3 Mbps upstream.
converged multimedia applications
Wireless local area network (WLAN):
low-cost, high-bandwidth
A user with WLAN access could be connected
through appropriate multi-access (WLAN and
cellular) terminals to the Internet, to the PSTN,
or to mobile network(s).
FMC + Access Technologies
Wireless Interoperability for Microwave
Access (WiMAX) :
Broadband wireless access (BWA). 2 - 11
GHz frequency band range (as per IEEE
specification in 2004).
Unlicensed Mobile Access
(UMA):roaming between a cellular network
and fixed IP-based wireless networks.
FMC in Some Places Include
 Multi Media Messaging Service (MMS)
 WLAN with CDMA service
 Integrated Portal Service
Multi Media Messaging Service
(MMS)
• MMS allows mobile phone users send and
receive messages with formatted text
graphics, photographs and audio –video
clips.
• With the integration of digital camera and
mobile phone, MMS usage increases.
WLAN with CDMA
• In a zone where an access point is
established, subscribes use WLAN
service. When the subscribers are out of
zone, they use CDMA.
• High speed, low price from WLAN
• Wide coverage from CDMA
Integrated Portal Service
• Integration of mobile and Web-based
portals.
• It provides aggregated content and
services through a mobile Internet
network.
Current Typical Solutions for
FMC
IP-PBX or soft-switch with mobile n/w
interface
IMS based coverage solution
UMA Dual Mode solution
What is IP-PBX???
• The Internet Protocol Private Branch eXchange
(IP PBX) is telephone switching equipment that
resides in a private business instead of the
telephone company.
• An IP PBX delivers employees dial-tone, the
ability to conference, transfer, and dial other
employees by extension number as well as
many other features. (Virtual Private Network
Services..)
• Voice transmissions are sent via data packets
over a data network instead of the traditional
phone network
• Least Routing of cellular.
• 3G ???(not applicable to 3G)…

infrastructure.
• Reduces on-campus and inter-campus calls.
• Only with in campus
• 3G????(not applicable because IP-PBX does
not support)
(companies like Nokia, Avaya, Motorola use this
technology).
FMC using SIP
• FMC solutions aimed at wireline operators
take an opposite approach from those
aimed at wireless providers
• Wireline-oriented FMC solutions are based
on SIP standards
• SIP approach has benefits since SIP has
already entered the emerging wireless
network (via 3GPP) and is inherently
compatible with IMS architecture
INTRODUCTION to SIP
• H.323 protocol
• Session initiation protocol
• SIP considered to be a simpler, more flexible
alternative to H.323 with the ability to support
advanced services.
What is SIP
 SIP or Session Initiation Protocol is an application-level
control protocol for setting up, changing and terminating
multimedia sessions between participants on IP data
networks.
 SIP is a text-based protocol, similar to HTTP and SMTP,
for initiating interactive communication sessions between
users. Such sessions include voice, video, chat,
interactive games, and virtual reality.
SIP Architecture
SIP Entities
• User Agent
User Agent Client
User Agent Server
• Proxy Server
• Redirect Server
• Registrar Server
How SIP works
• Long distance calls through the traditional telephony
• Telephony system works via a cog and wheel setup
• SIP refers to a protocol that allows computers to talk to
each other without going through a central station.
• SIP is typically offered in two formats, computer based
and hardware based

SIP structure
SIP based FMC solution
SIP in FMC
• FMC is likely to bring to reality the following
scenarios hitherto considered impossible.
– A cell phone user may start receiving calls on his SIP home
phone when he enters his home, saving spectrum and charges
for the ‘home roaming usage’. This kind of hand-off is both
extremely non-intrusive and cost beneficial.
– Enterprise subscribers may roam their mobile number into a
business environment via one to many SIP devices. This may be
offered by a service bureau as a managed service.
Contd…
• Enterprise subscribers may roam their mobile numbers in their
enterprise network via one to several SIP devices. This further
establishes that none of the existing infrastructure will be rendered a
waste.
• Mobile subscribers may continue enjoying all enhanced services
available on their home PLMN networks in any roaming network
they are visiting and on their landline networks as well.
• Mobile subscribers may seamlessly roam between locations with
calls transparently following them irrespective of whether they are in
a cable zone or a public WiFi hot spot.
SIP in IMS
• The key technology behind IMS is the SIP
protocol
• Advantages of SIP
– Simple
– Extensible
– Flexible
– Familiar
SIP in IMS
Introduction to IMS
• IMS stands for IP Multimedia Subsystem
• IMS is a key enabler of Fixed-Mobile
Convergence
• IMS is an architecture that merges the
applications and capabilities of the Internet with
both wireless and wire line telephony, and
promotes fixed/mobile convergence.
• An IMS/SIP approach enables both voice and
data applications to run over IP, rather than
locking it into the mobile carriers' legacy
networks.
Layered Approach
• Access Network
– Transport ( Connectivity) layer
• Core Network
– Control Layer
– Service Layer
IMS Architecture Overview
Functional Architecture
Horizontal Integration of IMS
Advantages of Horizontal Integration
• Service Enablers and common functions
can be reused for multiple operations
• Operations competence required is more
generic
• Helps to provide interoperability and
reaming and other such functions more
economically to the consumer
Interoperability in IMS
Advantages over Existing Systems
• The core network is independent of a
particular access technology ( GSM,
WCDMA, CDMA and also WLAN)
• Integrated mobility for all network
applications
• Easier migration of applications from fixed
to mobile users
• Faster deployment of new services based
on standardized architecture
Advantages over Existing Systems
• New applications such as presence
information, videoconferencing, Push to
talk over cellular (POC), multiparty
gaming, community services and content
sharing.
• Evolution to combinational services, for
example by combining instant messaging
and voice
• User profiles are stored in a central
location
Issues Related to IMS
• Benefits need to be further articulated in terms of
actual savings.
• IMS is "operator friendly" which means that it
provides the operator with comprehensive
control of content at the expense of the
consumer.
• IMS uses the 3GPP variant of SIP, which needs
to interoperate with the IETF SIP.
• IMS is an optimization of the network, and
investments for such optimization are
questionable.
Substitution of Legacy System
CS vs PS
What is UMA?
Unlicensed Mobile Access
Unlicensed Mobile Access (UMA)
technology provides access to GSM and
GPRS mobile services over unlicensed
spectrum technologies, including Bluetooth
and 802.11.
 It establishes a standard for seamless
hand-off and roaming between a cellular
network and fixed IP-based wireless
networks .
UMA
• UMA lets mobile operators deliver voice, data
and IMS/SIP(IP Multi media Subsystem
/Session Initiated Protocol) applications to
mobile phones on Wi-Fi access network
using dual-mode mobile handsets.
• In order to promote the widespread adoption
of UMA technology, a number of leading
companies within the wireless industry have
jointly developed a set of open specifications.
UMA Protocols
• UMA is on top of it at the transport layer
(Layer 4) and has its own set of control
protocols .
UNC
 The UMA specification is based around UNC.
What is UNC???
A UMA Network Controller (UNC) acts as a
virtual base station,
providing handoff
between cellular
and Wi-Fi networks.
Cellular /UMA
How UMA Technology Works
• A mobile subscriber with a UMA-enabled,
dual-mode handset moves within range of an
unlicensed wireless network to which the
handset is allowed to connect.
• Upon connecting, the handset contacts the
UMA Network Controller (UNC) over the
broadband IP access network to be
authenticated and authorized to access GSM
voice and GPRS data services via the
unlicensed wireless network.
(Contd..)
•If approved, the subscriber’s current location
information stored in the core network is
updated, and from that point on all mobile
voice and data traffic is routed to the handset
via the Unlicensed Mobile Access Network
(UMAN) rather than the cellular radio access
network (RAN).
Roaming
• When a UMA-enabled subscriber moves
outside the range of an unlicensed wireless
network to which they are connected, the
UNC and handset facilitate roaming back to
the licensed outdoor network. This roaming
process is completely transparent to the
subscriber.
Handover
 Handover in:
The mobile station moves from macro network to a
UMAN.
 Handover out:
The mobile station moves from UMAN to macro
network.
 Handover UMA:
The mobile station moves with in a UMAN or from
UMAN to UMAN.
Handoff Specifications
Subject to mode selection, UMA shall support
seamless handover in and handover out
,provided the following conditions are true:
 The mobile station stays within the limits of
service (pedestrian state of motion)
 The mobile station remains during the time of
handover within the coverage of both the
networks.
 UMA shall manage bandwidth during handover
between macro network and UMAN.
Security in UMA
Different security mechanism operate at different levels:
• MS to AP – UMA does not mandate any security
mechanism, but can coexist with those available, such
WPA, WPA2, or WEP.
• MS to UNC – The UNC includes a security gateway
that provides mutual authentication and encryption for
the traffic across the WLAN and the broadband
connection.
• MS to core mobile network – The encryption and
authentication methods used by the MS when using
the GERAN are also used to protect UMA connections.
• MS to application server – An additional end-to-end
data application mechanism (for example, HTTPS)
may be used if needed.
Advantages
Availability & Pricing
 UMA could be used to provide better inbuilding coverage for customers who don't
get a good cellular signal in some areas,
including basements.
 It enables service providers to deliver voice at
a lower cost when handsets are within range
of an unlicensed wireless network.
Issues
 If a customer doesn't have a wireless network already
in the house, a wireless access point would be
needed in addition to a broadband link .
 The most expensive and technologically challenging
component of UMA solution is the Wi-Fi and cellular
handset, because of battery-life limitations, cost, and
size .
 UMA cannot guarantee the quality of a voice call or
the throughput of a data connection and traffic
prioritization with QoS can significantly improve
performance, especially in a residential environment
where traffic is likely to be less heavy than in the
enterprise.
