IP-based multimedia services
UMTS
Forum
The UMTS Forum proposes a single service concept to
provide customers worldwide with a unified set of
multimedia services, irrespective of access technology
and location.
This service concept is based on:
! the integration of mobile communications and Internet
technologies which will bring the power and richness of
Internet services to the mobile environment and
! the interoperability between fixed and mobile networks
which will allow users to experience seamless converged
services.

Key IMS features
UMTS
Forum
Features
Comments
Real-time, person-toperson, multimedia
IMS will have the ability to deliver enhanced
speech telephony services (including
videophone) using packet technology
Real-time and non realtime services interaction
IMS allows for interaction of real-time and non
real-time services within a single session (call)
Multimedia call model
IMS allows simultaneous use of:
! Multiple multimedia services within a single
session
! Multiple sessions between multiple users
and devices
The user perceives this as service integration
Network interoperability
IMS includes the ability for real-time, personto-person communications, including
exchanging presence and location information,
with other IP networks.

Mobile Videophone service
UMTS
Forum
AT&T’s prototype Picturephone dates back to the 1920s.
More recent consumer interest in video technology has
fostered the introduction and growth of video services.
! Instant messaging “video chat” services (often available at
no charge on the Internet) using Web cameras
! Mobile videophone services for both real-time and
streaming video
The addition of mobility and presence to the videophone
concept has renewed market hopes for a commercially
viable consumer service.

Benefits of mobility and presence
UMTS
Forum
Benefits of mobility
Description
Further field of vision
Since the camera is mobile, it can be
pointed wherever the user desires
Expanded use in time and
place
Mobile Videophone Service would be
accessible from any place within the
mobile operator service area
Benefits of presence
Description
Increased control
Presence allows the called parties to
decide when and how they will accept
a video call.

Additional benefits of IMS
UMTS
Forum
Benefits
Description
Further expanded use in
time and place
With IMS the service would be accessible from
any place within the mobile operator service
area and to other networks. In addition, it is
possible to exchange media elements between
mobile and fixed Internet environments.
Increased interpersonal
connection through
terminal interoperability
and integration of services
The use of SIP and other existing Internet and
video standards will enable increased
interoperability between different terminal
types. Greater integration of services creates a
more natural personal experience.
Guaranteed call
completion
Call completion does not depend on the called
party having a compatible terminal. Calls can
be accepted without the video component, or
the video component can be routed to a
different destination.

Deployment aspects
UMTS
Forum
Operator decisions regarding the introduction of new IMS
technology must consider the following points:
! business plans,
! availability of similar capabilities in fixed networks and in
the Internet,
! impact of delaying deployment (or partial deployment) on
the take-up of 3G services and
! competitive positioning.

Conclusions
As it continues to guide the industry on 3G service
requirements, user expectations and market
opportunities, the UMTS Forum is proposing a single
service concept for IP-based multimedia services.
