FMC: DefinitionsETSI:

Fixed Mobile Convergence (FMC) is concerned with the provision of network capabilities which are independent of the access technique.This does not imply the physical convergence of networks. It is concerned with the development of a converged network architecture and supporting standards. This set of standards may be used to offer fixed, mobile or hybrid services.An important feature of fixed mobile convergence is the separation of the subscriptions and services from individual access points and terminals and to allow users to access a consistent set of services from any fixed or mobile terminal via any compatible access point. An important extension of this principle is related to internetwork roaming, users should be able to roam between different networks and to be able to use the same consistent set of services through those visited networks".

Q.1761

The Recommendation describes requirements for the use of fixed networks in the role of fixed access networks for IMT-2000networks.This convergence of fixed networks and IMT 2000 networksenables mobile users:

to roam outside the serving area of their IMT 2000 network and still have access to the same set of services outside their IMT-2000 network boundaries as they do within those boundaries.

The recommendation also describes the framework for fixed mobile convergence and the capability requirements for enhanced fixed terminals that may be utilized to enhance the roaming IMT 2000 user’s experience. The Recommendation also details the mobility managementfunctional requirements in fixed networks in support of roaming IMT 2000 subscribers

FMC Service Solutions

Fixed-mobile convergent (FMC) solutions represent exceptional defences against FMS. There are in essence three types of FMC solution:

FMC bundles, where fixed and mobile services are bundledtogether often as flat-rate packages and with a single bill. Verizon, SBC and BellSouth have launched such servicesFMC network-based solutions, which use intelligent networkplatforms to route calls to the fixed or mobile phone as the customer chooses. One number and a single voicemail are often features of such applications. TDC's Duet, Cingular's Fast Forward and Verizon's iobi are examples of such solutionsFMC phones, which combine cellular and Bluetooth/WLANtechnologies in a handset. The device acts as a normal mobile phone until the user is within the range of a Bluetooth/WLAN base station when the calls are routed via them through the fixed line. BT, Telecom Italia and a number of other operators are running trials of such handsets at present.

Pre IMS FMC: CTP and UMA

Cordless Telephony Profile (CTP) and Unlicensed Mobile Access (UMA) are, very loosely, two alternative short-range wireless standards that enable fixed-mobile convergence (FMC) solutions.Most players in the FMC space see UMA as the long-term future technology. However, CTP is being deployed by some manufacturers, and some operators, as an interim solution, because CTP equipment is available now and can be attached to existing networks without any changes.

CTP (Cordless Telephony Profile)

CTP is a profile defined within the Bluetooth specification, by the Bluetooth Special Interest Group, which allows a Bluetooth-enabled mobile phone to be used as a cordless telephone when it is within range of a Bluetooth CTP access point. CTP is thus a way of adding limited mobility - cordlessness - to the fixed network.CTP acts as an application on the device - which is sometimes a mobile phone and sometimes a hands-free headset. The simplest implementations simply use Bluetooth as a local air interface comparable to DECT. Here, the access point plugs directly into an analogue telephone line. Bluetooth Class 1 chips that allow communications over ranges 'up to' 100m are beginning to become available and to be included in mobile devices. This is still not as good as DECT range, but CTP has the advantage of being present in mobile devices and having access to their address books and presentation capabilities.Mobile and fixed access are only loosely converged in CTP. The mobile device retains its GSM number, whereas the CTP access point uses the number associated with the fixed line to which it is attached.

UMA (Unlicensed Mobile Access)

In its earliest implementation, UMA is also a way of using Bluetooth to provide limited mobility, using a cordless link and an access point connected to the fixed network. Although it is superficially similar, UMA is actually very different from CTP. For a start, while CTP is limited to the Bluetooth airinterface technology, UMA is an 'air interface agnostic' specification, which can be used in conjunction with Bluetooth, WiFi or even as yet undefined access technologies. The specification has been developed by a group of manufacturers, with limited input from some operators, notably BT, who intends to use it for its Bluephone deployment. The group is now taking the specification through the 3GPP GERAN standards process 1)

The UMA solution has now become a 3GPP standard named GAN (Generic Access Network) 2)

Strategic significanceDespite the similarities, CTP and UMA have quite different strategic implications CTP is a technology for avoiding the mobile network, and for providing a limited amount of mobility on the fixed networkUMA is a technology for extending the mobile network into the building. Although it uses a part of the fixed network in its access method, the call and the subscriber remain under the control of the mobile networkIt is open to fixed operators to deploy a UMA-based network (provided that their regulator and their licence conditions allow), but they can only do so if they have equipped themselves with a mobile core network - and indeed with the operator-owned radio access network elements For fixed operators, deploying UMA is not only a response to mobile operators' strategies, and to increasing fixed-mobile substitution. It is also intended to be a weapon in the fight back against cable operators' inroads into the fixed market, with the mobility aspect allowing conventional telephone operators to offer a different kind of 'triple play' package

IMS Adoption Phases

Mobile VoIP QoS issues dealt with. Now two distict‘horizontal’ propositions in both fixed and mobile: one based on services, the other on access.

Billing, customer care and user information issues start to be dealt with consistently. Solution maturity brings mainstream market online.

Limited handset availability. Initial technology supplier direction and partnerships are enterprise-focused. Simplest IMS services are more of value to businesses.

Why ?

Broad interconnection and availability of IMS services across all fixed and mobile networks for voice and data. VoIP over mobile brings all services into IP domain.

Operator interworking and significant IMS-capable service deployments. Broader range of agreements spanning fixed and mobile.

Some initial mobile deployment, but services limited in subscriber reach. Likely initial focus in business customers.

What ?

‘Towards the 4G Vision’Stable; full IMS benefits being realisable

‘IMS becomes Real’Early; some benefits are demonstrated

‘The bandwagon rolls’Emerging; first-mover advantage being sought

IMS Trials & DeploymentTrials:

by Jan 2005 around 30 operators have conducted IMS trials 1)

by Jan 2006 around 200 operators are already in trials or in the early stages of IMS deployment 2)

Early deployment examples 2) :BT Group plc‘ have largely announced their 21st Century Network, based upon IMS and SIP infrastructureTelecom Italia Mobile SpA have launched a video-sharing service over its 2.5G and 3G networksIn the U.S., BellSouth Corp. is deploying SIP-based infrastructure

SIP interoperability trials 2) :GSMA has organized trials using infrastructure based on the IMS standard, handsets provided by Nokia using test applications such as voice instant messaging, video sharing and gaming, employing both 2G and 3G access networks.Trials involved six mobile operators (KPN, Orange, SFR, Telenor, TeliaSonera and Vodafone), four GRX carriers (Belgacom, Cable & Wireless, KPN and TeliaSonera), and three infrastructure vendors (Ericsson, Nokia and Siemens).

Regulatory issues raised by FMC

Spectrum – access to licensed and unlicensed spectrum, deregulation of existing allocations and spectrum trading

Numbers – geographic numbers for non geographic services, converged “voice services” numbers, ENUM and mapping telephone service to Internet services

Number portability – “intermodal” portability between fixed and mobile networks

Interconnection – mobile party pays (MPP), calling party pays (CPP), symmetry of charging and cost base
