Lets Set the Stage(for this session)
Convergence and Next Generation Networks
NGN Vision
What is IMS?
IMS and Convergence
3
Convergence in the Dictionaryfrom the late Latin convergere, to incline together convergence is a coming together of two or more distinct entities or phenomena
Convergence in Technologythe combination of two or more different technologies in a single device. Such as taking photos with a mobile phone and reading emails on a refrigerator
Fixed Mobile Convergence (FMC)the integration of mobile and fixed technologies to enable the seamless distribution of services over fixed and mobile broadband networks
What is Convergence?
4
From the ITU-T Packet-based network able to provide services including Telecommunication Services and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies. It offers unrestricted access by users to different service providers. It supports generalized mobility which will allow consistent and ubiquitous provision ofservices to users
Practical DescriptionThe convergence of the public switched telephone network (PSTN) voice network, the wireless network (WiFi / WiMax / 2G / 3G) and the data network (Internet)
What is a NGN?
5
Fixed Operator (with no Mobile assets) PerspectiveReverse the loss of voice-service minutes and revenue to mobile providers. (MNVOs)Reduce CAPEX and OPEX (harmonised network)Offer new value-added ServicesReduce Churn, attract new customers, market Brand
Fixed Operator (with Mobile assets) PerspectiveReduce CAPEX and OPEX (harmonised network)Offer new value-added Services - increase revenue
Mobile Operator PerspectiveReduce CAPEX and OPEX (harmonised network)Offer new value-added Services`Improve coverage (indoor / outdoor Wi-Fi)

. and lets not forget the customerUsers can be contacted with a single number independent of the network connection or locationSingle billing for multiple services (mobile calls / fixed / broadband / TV)New innovative servicesPossibility to have the same services independent of location and underlying technology with the same look and feelPossibility to personalize services and define profilesReduction of the number or devices requiredIncreased Mobility
Motivators for FMC

The NGN Vision
Mobile/Fixed Convergence, based on the IMS platform A multi-service multi-protocol, multi-access, IP based network - secure, reliable and trustedMulti-services: delivered by a common QoS enabled core network. Multi-access: diverse connectivity networks; fixed and mobile terminals, (Mobile, xDSL, etc)Not one network, but different networks that interoperate seamlesslyMobility / Nomadicity of both users and devicesMy communications services
anywhere, any terminal>>> all of this leads to a true Next Generation Network

IP Multimedia Subsystem as defined by 3GPP3GPP IMS standards define a network domain dedicated to
the control and integration of multimedia services.IMS is defined by 3GPP from Release 5 onwards (2002)3GPP2 equivalent of IMS is the MMD (MultiMedia Domain),
fully interoperable with 3GPP IMSIMS builds on IETF protocols
Based upon SIP, SDP, COPs and Diameter protocols3GPP have enhanced these IETF protocols for mobility
IMS in shortOpen-systems architecture that supports a range of IP-
based services over both PS and CS networks, employing both wireless and fixed access technologies
What is IMS?
9
Services and ControlAdds call session control to the packet network (GPRS)enables peer-to-peer real-time services - such as voice, video - over a packet-switched domain scalable common service control (based on SIP) give the ability to manage parallel user services
Media MixingAbility to pick and mix various multimedia flows in single or multiple sessionsCan handle real-time voice, video, data
Access IndependenceProvides access to IP based services independent of the underlying access technology (mobile / fixed)
What does IMS provide?
10
Why IMS in NGN?IP Multimedia Subsystem generally fulfills the NGN requirements for conversational services
For managed, carrier operated telecom networkWith Release 6 IMS becomes applicable to a range of access network types (3G RAN, WLAN)
Whole Telecom industry benefitsIMS is being proclaimed as the architecture of choice for converging networks (mobile fixed), as well as Voice and MultimediaIt is predicted that IMS will enable IP to gradually replace circuit switched voiceOperators who own both fixed and mobile networks want to consolidate their networksGrowing IMS market, will encouraging greater usage and creation of new IP based servicesOpen interfaces allow for a wider choice of IMS suppliersMarket stimulation, decreasing costs (thanks to shared development/deployment costs)
11
IMS is stable and well specified in 3GPP Rel-5
IMS is being tested worldwide by a number of operators and vendors
IMS is the platform of choice for Mobile to Fixed converged networks
3GPP and ATIS are working on a single IMS for fixed and mobile networks
Robust and open standards are essential to the long term success of IMS and NGN
Key points to take home
