This document discusses delivering fixed mobile convergence using IP Multimedia Subsystem. It explains why FMC and IMS are important, and how to start implementing them by breaking the vicious cycle. It outlines new applications like personal and terminal mobility. Research challenges are identified around maintaining quality of service during handovers between networks. The document proposes establishing a testbed to develop applications and demonstrate IMS capabilities to operators and manufacturers. Milestones for 2008 include setting up an IMS testbed and identifying requirements.

3. Why
FMC?
• Wireless
network
+
fixed
network
+
internet
service
crea5on
&
paradigm
à
All
IP
network
• Overlay
of
various
networks
à
allows
many
IP-‐based
apps
to
be
func5onal
on
the
move
• As
networks
converged
à
need
for
seamless
connec5vity,
to
access
different
services
regardless
of
loca5on,
terminal
and
network
4. Why
IMS?
• Operators
need
to
create
new
revenue
streams,
cut
expenditures,
but
extend
their
value
chain
up
to
service
crea5on
• Improved
end-‐user
experiences
• Standardized
IP
mul5media
environment,
developed
by
ETSI
TISPAN
and
3GPP
5. How
do
we
start?
• Must
Break
the
Vicious
Cycle
Where are the

6. MIMOS
CoE
• Set
up
a
testbed
for
applica5on
developers
and
users
to
try
out
new
services
• Create
new
and
exci5ng
applica5ons
to
aZract
more
users
• Demonstrate
to
both
telcos
and
device
manufacturer
the
importance
of
suppor5ng
IMS
7. New
and
exci5ng
applica5ons?
• Personal
mobility
• Terminal
mobility
8. Applica5on
(1):
Personal
Mobility
• On
his
desktop
(Ethernet),
Bob
sees
that
Jane
is
available
with
the
help
of
the
IMS
presence
server
• Bob
decided
to
talk
to
Jane
by
giving
her
a
call
• Jane
accepted
the
call
and
they
started
talking
• A`er
a
while,
Bob
feels
thirsty
and
wanted
to
get
a
drink
from
the
Pantry.
• So,
Bob
switches
the
call
from
his
desktop
onto
his
PDA
(WiFi),
and
con5nue
talking
to
Jane
on
his
way
to
the
Pantry.
9. Applica5on
(2):
Terminal
Mobility
• On
his
laptop
at
home,
Bob
starts
an
audio
conference
with
his
business
counterpart
• Before
the
mee5ng
finishes,
Bob
rushes
into
a
Taxi
as
to
meet
up
a
customer
at
the
coffee
shop
in
Town
• While
on
mobile,
Bob
con5nues
with
his
mee5ng
using
his
laptop
