Introduction:3 The tremendous grow of the mobile network The significant advances of the broadband wirelesstechnologies has led to : The development and the transition to Next Generationmobile Networks which is taking a huge step. 4. The next generation networks (NGN) provide thetechnical underpinning of convergence, representing asingle transport platform on which the carriage ofdifferent service types (video, voice, and data)converges, together with new and emerging servicesand applications.4 5. The Next Generation Mobile Network (NGMN)introduction roadmap overview is illustrated. It clearlyshows the coexistence of various technologies and theneed for minimization of their diversity.5 6. 6 7. The NGMN high-level roadmap points out towards theone integrated all-IP network. According to ITU NGN is A Next Generation Networks(NGN) is a packet-based network able to provideTelecommunication Services to users and able to makeuse of multiple broadband, QoS-enabled transporttechnologies and in which service-related areindependent of the underlying transport-relatedtechnologies. It enables unfettered access for users tonetworks and to competing service providers andservices of their choice. It supports generalised mobilitywhich will allow consistent and ubiquitous provision ofservices to users.7 8. NGN, also defined as broadband managed IP networks,includes next generation core networks, which evolvetowards a converged IP infrastructure capable of carryinga multitude of services, such as voice, video and dataservices, and next generation access networks, i.e. thedevelopment of high speed local loop networks that willguarantee the delivery of innovative services.8 9. NGN Access Networks The definition of next generation access networks isusually specific to investment in fibre in the local loop. In general, this is the definition used in a number ofnational initiatives in examining NGN.9 10. The different technologies available include existingcopper networks upgraded to DSL, coaxial cablenetworks, powerline communications, high speedwireless networks , or hybrid deployments of thesetechnologies. Fibre, in particular point-to-point fibre development, isoften described as the most future proof of networktechnologies to deliver next generation access10 11. CableCable television (CATV) operators have begun toupgrade their infrastructure to hybrid fibre copper (HFC)allowing for bidirectional traffic and to increase networkcapacity These developments are allowing CATV companies tooffer voice and Internet access (data services) incompetition with telecommunication companies whichthrough their offer of Internet TV have begun to competewith CATV companies. Offering data and voice services, in addition to television,helps cable companies differentiate their product offeringfrom satellite providers.11 12. Broadband Wireless Access (BWA)BWA technologies aim at providing high speedwireless access over a wide area. Certain early fixedwireless access technologies did not had a greaterimpact.Wi-Fi (or wireless fidelity) refers to wireless localarea networks Wi-Fi allows LANs to be deployedwithout cabling for client devices, typically reducingthe costs of network deployment and expansion.Due to its affordability, scalability and versatility, itspopularity has spread to rural and urban area.12 13. 3G mobile networks The term next generation networks frequentlyencompasses some kind of fixed-mobile convergence(FMC), as it allows the transition from separate networkinfrastructures into a unified network for electroniccommunications based on IP, which facilitate affordablemultiple play business models,seamlessly integratingvoice, data and video. The introduction of 3G technology supports thetransmission of high-speed data with speeds theoreticallyreaching 2/4 Mbit/s, and third-generation handsets giveusers access to the Internet and content on the go.13 14. NGN Core NetworksThe definition of next generation core networks aredefined on the basis of their underlying technologicalcomponents that include as mentioned in the ITUdefinition packet-based networks, with the servicelayer separated by the transport layer, whichtransforms them into a platform of convergedinfrastructure for a range of previously distinctnetworks and related services14 15. IP-based network: Next generation corenetworks generally cover the migration frommultiple legacy core networks to IP-based networksfor the provision of all services. This means that allinformation is transmitted via packets. Packets cantake different routes to the same destination, andtherefore do not require the establishment of an end-to-end dedicated path as is the case for PSTN-basedcommunications. The core will be IPMultimedia Subsystem (IMS) based.15 16. Packet-based, multi-purpose: While traditionallyseparate networks are used to provide voice, data andvideo applications, each requiring separate accessdevices, with NGN different kinds of applications can betransformed into packets, labelled accordingly anddelivered simultaneously over a number of transporttechnologies, allowing a shift from single purposenetworks (one network, one service), to multi-purposenetworks (one network, many services). Interworkingbetween the NGN and existing networks such as PSTN,ISDN, cable, and mobile networks can be provided bymeans of media gateways.16 17. Separation of transport and service layer: Thisconstitutes the key common factor between NGN andconvergence, bringing about the radical change inrelationship between network layers (transportinfrastructure, transport services and control, contentservices and applications). In next generation networksservice related functions are independent from underlyingtransport-related technologies The uncoupling ofapplications and networks allow applications to bedefined directly at the service level and providedseamlessly over different platforms, allowing for marketentry by multiple service providers on a non-discriminatorybasis. These features may foster thedevelopment and provision of new service17 18. Separation of the functional plansin two NGN stratums.18 19. General NGN functional model19 20.

Introduction Fixed operators Many fixed phones replaced with mobile phones Mobile operators Lacking of high bandwidth Hybrid operators Expensive to maintain two separate networks Mobile virtual network operators (MVNOs) Need to offer their services via different kinds ofaccess networks22 New strategies needed, FMC is one possibility 23. Introduction FMC gives possibilities to different types of operators: Fixed operators Possible to enhance their coverage area towards mobile access Mobile operators Possible to enhance their coverage area Hybrid operators Can reduce costs by optimizing their networks Mobile virtual network operators (MVNOs) Possible to utilize both fixed and mobile operators networks23 24. Fixed Mobile Convergence FMC concept is not new FMC target:To have all services seamlessly available from any network and with any terminal device Separate wireless and wireline networks will merge toone several access technologies available to accessthe network IMS architecture and SIP protocol are the main buildingblocks IMS handles SIP sessions between the terminals24 25. Definition of FMC25Fixed and Mobile Convergence (FMC) is concerned with the provision ofnetwork and service capabilities, which are independent of the accesstechnique. This does not necessarily imply the physical convergence ofnetworks. It is concerned with the development of converged networkcapabilities.An important feature of FMC is to allow users to access a consistent setof services from any fixed or mobile terminal via any compatible accesspoint. An important extension of this principle is related to roaming: usersshould be able to roam between different networks and be able to use thesame consistent set of services through those visited networks. Thisfeature is referred to as the Virtual Home Environment (VHE). 26. Fixed-Mobile Convergence allows users to buy and use awider range of personalized services . The primary device willbe portable and for most applications it will be a multi-radiodevice, supporting voice and multimedia services. Users can be contacted with a single number independent ofthe network connection. The target of convergence is to enableeasy implementation for the operator and service provider, andeasy usage of services for end users. This will enable truemobility for users in both the residential and businessenvironment.26 27. End User Services FMCA Fixed mobile convergence association has listed convergence service scenarios Converged contacts personal contact and address book in the network-basedstorage which is accessible from anywhere Personal multimedia - secure access to the users multimedia content that is storedin home or in the network from any device Multimedia call with data sharing service possible to for the user to switchbetween voice only GSM call and multimedia call containing e.g. picture orbroadband-enabled TV Combinatorial services - based on availability of multiple connections (circuit anddata) during the same communication session Electronic Programme Guide service is listing available programmes that can bewatched on the mobile device or recorded on video recorder Automation control and monitoring service makes it possible to control varioushome based tasks via the mobile device such as temperature and access Convergent call control provides the ability to automatically handle the call basedon some events. For example based on the information of the users electroniccalendar, the location of the user and the importance of the caller the call will beconnected to the user or to the voice mail Multimodal services include several scenarios where voice and data sessions aremixed27 28. Influence to Operator BusinessModels FMC offers two main benefits to the operators: Interoperability reduction of the costs because common resources can be used FMC introduced step-by-step Operators want to exploit their existing investments Interworking with existing networks is important FMC solutions must be adjusted to each operator Investment plans the amount of investments is going to increase because of theequipment needed for convergence and next generation networks operators believe that they will get remarkable cost savings by usingIP based techniques Also they believe that convergence will bring new services for endusers28 29. Influence to Operator BusinessModels FMC is a continuously changing and complexenvironment which creates uncertainties attechnology, demand and strategy levels The technological uncertainties are caused by rapidtechnological development and the developingstandards What are the services that the users are willing to paywill be seen in the future. This is causing uncertainty indemand level A clear framework is needed to prevent the operators todo costly mistakes by entering and subsequently exitingnon-core businesses and markets29 30. Vendor Strategies Operators want to reuse their existing networks=> This has to be taken into account by vendors Many vendors have different kinds of evolution pathsand step-by-step network introduction to the FMCand all IP networks Most of the vendors have taken an active role in manystandardization bodies=> standardization is a key issue if vendors want toprovide solutions that can be integrated to theequipment of other vendors30 31. The combination of fixed and mobile networks - Fixed MobileConvergence (FMC) Any combination of mobile and fixed access, voice, video and data servicesdecrease operational costs by using common resources FMC implementation leads to a new market with unique list of services andhigh revenue potential Fixed-Mobile Convergence allows network and service operators to makemore efficient use of existing access technologies (GSM, DSL, Wi-Fi), as wellas taking an advantage of the roll-out of new access technologies such as3G, WLAN, Bluetooth, Wi-Max UMA, etc, by launching new voice &multimedia services and realizing cost reductions by implementing commonservice machinery for different access networks.31 32. Whats Life Like . In early years.. Most people cant do without their mobile phones Content is on DVDs or magazines or books or a local hard-disk Contact Lists are by application, device, and individual situation Today Everyones connected and cant do without being on-line The first place people go for content is on-line Informal peer groups and sharing are commonplace In 2015 Everyone and everything is connected all the time.ywhere The only place people go for content is on-line Dynamic communities of interest without any boundaries32Todays technology savvy young person istomorrows decision maker: our target customer! 33.

Two of the Key enabling technologies for FMC are SIP,IMS . The description of these technologies are given below. SESSION INTERNET PROTOCOL(SIP):SIP is a protocol developed by IETF(Internet engineeringtask force) which can initiate modify and terminateinteractive multimedia communication session. IP MULTIMEDIA SYSTEM(IMS):IMS is an architecture standard based on SIP which allowsfor multiple real time applications such as voice video gamesetc to run on a single network.38 39. FMC Challenges Number plans and number portability Fixed and mobile numbers come from separate blocks and they have prefixes thatcontain information for interconnection charging Currently there is separate fixed number portability and mobile number portabilityavailable but not fixed/mobile number portability Directory services Fixed operators provide directory service to their customers. This catalogue containsinformation on all fixed line customers Currently mobile operators do not offer this kind of service and mobile numbers areconsidered as personal data Handset availability Always a problem in the early stages of any telecommunications technology39 40. Conclusion FMC gives lots of possibilities but on the other hand itmeans also new investments to operators Very complex networks Common standards have a great importance How much the end users are willing to pay for theservices?40 41.
