71 Fixed-mobile convergence IMS definition standardization
A Definition of FMC
The following definition of FMC is based on the ETSI FMC ad hoc workgroup docs
Fixed and Mobile Convergence (FMC) is concerned with the provision of network and service capabilities which are independent of the access technique This does not necessarily imply the physical convergence of networks It is concerned with the development of converged network capabilities and supporting standards This set of standards may be used to offer a set of consistent services via fixed or mobile access to fixed or mobile public or private networks

B FMC motivationsCustomer motivations ndash more mobility with required list of services
The FMC greatest benefits - for the end-user Mobility of people and the need to communicate on the move Conventional fixed networks continue to serve the home or the office Wide range of services within a uniform network Quality standards regarding reliability security etc
Three aspects of mobility - terminalservicepersonal mobility
bullTerminal mobility - the use of personal terminal at any place
bullService mobility - set of services independent of the access type and location
bullPersonal mobility - the customer is reachable with one number his personal number everywhere

Service convergence
Focus - on end-user requirements and the service experience The primary goal is the concurrent delivery of all media types mdash voice data and videomdash to an easy-to-use graphical user interface with mobility access and device awareness Multitude of services (person-to-person person-to-content and content-to-person) can be provided to the same user over different access networks and to different devices From a service perspective the consumer and enterprise user expect convenience ease of use reliability security and support to be always connected in the best way

D IMS Definitionbull The IP Multimedia Subsystem (IMS) is a standardized NGN architecture
for telecom operator that want to provide mobile and fixed multimedia services It uses a VoIP implementation based on a 3GPP standardized implementation of SIP and runs over the standard IP Existing both PS and CS systems are supported
bull The aim of IMS - providing all services for fixed and mobile usersbull IMS provides the unified architecture that supports a wide range of IP-
based services over both packet- and circuit-switched networks employing a range of different wireless and fixed access technologies
bull IMS uses open standard IP protocols bull Interfaces for service developers are also based on IP protocolsbull For providers - the ability to control and charge for each service bull For users ndash the ability to execute all their services when roaming as well as
from their home networks

telecommunications specifications-setting project comprising North American and Asian interests developing global specifications for ANSITIAEIA-41 network evolution to 3G
bull 3GPP2 was born out of the ITU International Mobile Telecommunications IMT-2000 initiative covering high speed broadband and IP-based mobile systems featuring network-to-network interconnection service transparency global roaming and seamless services independent of location

Key attractions of IMS bull Access independence IMS will eventually work with any network (fixed
or mobile) with packet-switching functions such as CDMA2000 GPRS UMTS and WLAN Open interfaces between control and service layers allow elements and callssessions from different access networks to be mixed
bull Different network architectures IMS allows operators and service providers to use different underlying network architectures
bull Terminal and user mobility The mobile network provides terminal mobility while user mobility is provided by IMS and SIP
bull Extensive IP-based services IMS should make it easier to offer just about any IP-based service Examples include voice over IP (VOIP) push-to-talk over cellular (POC) multiparty gaming videoaudio conferencing and content sharing

B FMC motivationsCustomer motivations ndash more mobility with required list of services
The FMC greatest benefits - for the end-user Mobility of people and the need to communicate on the move Conventional fixed networks continue to serve the home or the office Wide range of services within a uniform network Quality standards regarding reliability security etc
Three aspects of mobility - terminalservicepersonal mobility
bullTerminal mobility - the use of personal terminal at any place
bullService mobility - set of services independent of the access type and location
bullPersonal mobility - the customer is reachable with one number his personal number everywhere

FMC motivations bullOperator motivations ndash better position on the market ndashincreasing
revenue gaining new users
FMC can be understood as a marketing strategy to attract new customers by
launching new innovative products
Offering customized set of attractive services (VPN VHE hellip)

D IMS Definitionbull The IP Multimedia Subsystem (IMS) is a standardized NGN architecture
for telecom operator that want to provide mobile and fixed multimedia services It uses a VoIP implementation based on a 3GPP standardized implementation of SIP and runs over the standard IP Existing both PS and CS systems are supported
bull The aim of IMS - providing all services for fixed and mobile usersbull IMS provides the unified architecture that supports a wide range of IP-
based services over both packet- and circuit-switched networks employing a range of different wireless and fixed access technologies
bull IMS uses open standard IP protocols bull Interfaces for service developers are also based on IP protocolsbull For providers - the ability to control and charge for each service bull For users ndash the ability to execute all their services when roaming as well as
from their home networks

bull Different network architectures IMS allows operators and service providers to use different underlying network architectures
bull Terminal and user mobility The mobile network provides terminal mobility while user mobility is provided by IMS and SIP
bull Extensive IP-based services IMS should make it easier to offer just about any IP-based service Examples include voice over IP (VOIP) push-to-talk over cellular (POC) multiparty gaming videoaudio conferencing and content sharing

Key attractions of IMS bull Access independence IMS will eventually work with any network (fixed

bull Different network architectures IMS allows operators and service providers to use different underlying network architectures
bull Terminal and user mobility The mobile network provides terminal mobility while user mobility is provided by IMS and SIP
bull Extensive IP-based services IMS should make it easier to offer just about any IP-based service Examples include voice over IP (VOIP) push-to-talk over cellular (POC) multiparty gaming videoaudio conferencing and content sharing

Key attractions of IMS bull Access independence IMS will eventually work with any network (fixed

bull Different network architectures IMS allows operators and service providers to use different underlying network architectures
bull Terminal and user mobility The mobile network provides terminal mobility while user mobility is provided by IMS and SIP
bull Extensive IP-based services IMS should make it easier to offer just about any IP-based service Examples include voice over IP (VOIP) push-to-talk over cellular (POC) multiparty gaming videoaudio conferencing and content sharing

Key attractions of IMS bull Access independence IMS will eventually work with any network (fixed
or mobile) with packet-switching functions such as CDMA2000 GPRS UMTS and WLAN Open interfaces between control and service layers allow elements and callssessions from different access networks to be mixed
bull Different network architectures IMS allows operators and service providers to use different underlying network architectures
bull Terminal and user mobility The mobile network provides terminal mobility while user mobility is provided by IMS and SIP
bull Extensive IP-based services IMS should make it easier to offer just about any IP-based service Examples include voice over IP (VOIP) push-to-talk over cellular (POC) multiparty gaming videoaudio conferencing and content sharing
