and
Challenges in Convergence
Delivering multimedia services across fixed and mobile accesses.
Augmenting multimedia services – including voice, pictures, text and video - to
existing services.
Utilizing and reusing a common core and control, to the fixed, mobile and cable
communities.
Preserve quality and interoperability of telecoms with the quick and innovative
development of the Internet.
Mixing-and-matching equipment and applications from multiple vendors
Handle non-standardized services in a standardized way – ensuring the
interoperability, access awareness, policy support, charging, security and
quality of service functionality
Interworking with existing networks
Enabling users to enjoy converged multiple services regardless of access
network and device (access-independent)
Enabling mobile users to access their personal set of services wherever they
roam, whichever operator network they are connected to.
The Magic Potion…
IMS
IMS in a Nutshell
The IP Multimedia Subsystem (IMS) standard defines a generic
architecture for offering Voice over IP and multimedia services.
International standard specified by the 3GPP/3GPP2 being embraced
ETSI/TISPAN.
Supports multiple access types
GSM, WCDMA, CDMA2000, Wireline broadband access and WLAN.
For Users
Enable person-to-person and person-to-content communications – including voice, text,
pictures and video.
For Operators
Defines a horizontal architecture - service enablers and common functions can be reused
for multiple applications.
Specifies interoperability and roaming, and provides bearer control, charging and security.
Well integrated with existing voice and data networks - makes IMS a key enabler for fixedmobile convergence.
IMS in a Nutshell
Enables services to be delivered in a standardized, wellstructured way.
Provides a future-proof architecture
Simplifies and speeds up the service creation and provisioning process
…while enabling legacy interworking.
For fixed and mobile operators there are benefits of
introducing the IMS architecture today 
On longer term, IMS enables a secure migration path to an
all-IP architecture that will meet end-user demands for new
enriched services.
IMS becomes a preferred
solution for fixed and mobile
operators’ multimedia business.

IMS Layers
The Application/Service layer
Comprises application and content servers to execute services for the user.
Generic service enablers are implemented as services in a SIP Application Server (AS).
The Control layer
Comprises network control servers for managing call or session set-up, modification and release.
The most important – the CSCF (Call Session Control Function), also known as a SIP server.
Contains a full suite of support functions - provisioning, charging and operation & management (O&M).
Interworking with other operators’ networks and or other types of networks is handled by border
gateways.
Media Resource Function (MRF) – Control and Process Media Stream
The Access/Trasport layer
Comprises routers and switches, both for the backbone and the access network

The API – V2XML over HTTP
The Interactive Video Platform
behaves like a browser – it issues a
HTTP GET request and fetches a
V2XML page
Pages can be static, or dynamic written with standard web
technologies such as cgi, asp, jsp,
php etc.
