phone, one number and one bill Seamless roaming between cellular, Wi-Fi,
WiMAX and what ever wireless technology comes next.
More reliable mobile service with wider coverage at lower cost. Closer integration between public and enterprise phone networks.
Friendly user interfaces that makes it easy to make and manage calls (the user has a choice to select the type of network depending upon cost and convenience).
Features of FMC
• Friendly user interface that makes it easy to make and manage calls (the user has a choice of N/w depending upon chose and convenience).
Motivator FMC
• Fixed Operator (with no Mobile assets) Perspective– Reverse the loss of voice-service minutes and revenue to mobile providers
(MNVOs)– Reduce CAPEX and OPEX (harmonized network)– Offer new value-added Services– Reduce Churn, attract new customers, market “Brand”
• Fixed Operator (with Mobile assets) Perspective– Reduce CAPEX and OPEX (harmonized network)– Offer new value-added Services -increase revenue
• Mobile Operator Perspective– Reduce CAPEX and OPEX (harmonized network)– Offer new value-added Services`– Improve coverage (indoor /outdoor –Wi-Fi)
• Cable Operator Perspective – Can offer a quadruple bundling of VoIP, video, mobility and broadband
access services

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
• 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
A key component of FMC is cost efficiency – many implementationscan keep calls “on-net”, saving mobile minutes
FMC is designed to work in tandem with existing infrastructure, in many cases making it more useful
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.

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)…

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

Services that SIP can provide
• Call Hold• Consultation Hold• Unattended Transfer• Call forward on Busy/NoAnswer/Unconditiona 3-Way Conference• Find-Me• Incoming/Outgoing Call Screening• Call Waiting
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 SpecificationsSubject 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 in-building 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.
