(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 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

Page 41: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

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.

Page 42: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

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.

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 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.

Page 52: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

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.

Page 56: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

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.

Page 61: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

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

Page 63: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

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

Page 64: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

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

Page 65: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

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.

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 .

Page 70: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

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.

Page 71: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

UMA Protocols

• UMA is on top of it at the transport layer (Layer 4) and has its own set of control protocols .

Page 72: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

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.

Page 73: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

Cellular /UMA

Page 74: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with 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.

Page 75: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

(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).

Page 76: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

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.

Page 77: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

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.

Page 78: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

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.

Page 79: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA
Page 80: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

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.

Page 81: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

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.

Page 82: Topics  Introduction  Technologies in FMC  FMC with IP  FMC with IMS  FMC with SIP  FMC with UMA

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.
