Telecommunications Industry:
Constant Innovation
VoIP and Converged
Communications
Wireless to
WiMAX/4G/LTE
Wireline to Wireless
Copper to Fiber
Analog to Digital

Change comes from disruption.
And disruption is constant!
8
Discontinuities
Transition from Fixed to Mobile
Growth of fixed services slowing,
turning negative
Mobile phone growth continues but
levelling off due to market saturation
Chişinău, Moldova, 7 October 2011

Discontinuities
Transition from Analog to Data
On circuit-switched (analog or TDM) voice
networks, data is handled by making it look
like voice (modems)
Phone
Network
On packet switched data networks, voice is
handled by making it look like data (VoIP)

Discontinuities and Convergence
Once we just had a telephone on our desks.
Then we added a computer mainframe terminal,
but replaced that with a personal computer …
… which became portable (laptop), …
… we added wireless networking including voice,
but we shrunk them a
little too much …
… so we enlarged
them to just about
the right size.

Where Should Intelligence
Reside?
SG 13 Work on “Future Networks”
Some Thoughts on the Future

12
Intelligence was centralized,
but is it in the right place?
We began with human operators
“inside the network” handling
switching and services for
“hard-wired” subscribers, …
... “progressed” to analog
mechanical circuit switching (SxS), ...
... refined it with
stored program
control
(#5 XBar, SP1), ...
Chişinău, Moldova, 7 October 2011
13
We continued with the assumption
that terminals were “dumb” …
We converted from
analog to digital
transmission and
switching.
We centralized
network intelligence
into with replicated
islands of intelligence
enabled by common
channel signalling.
Chişinău, Moldova, 7 October 2011
14
… but ISDN and Mobility
changed everything!
Suddenly terminals had to be able to
do a great deal more:
A functional ISDN terminal is a
de facto 2 line exchange!
Cellular networks added
a new dimension to
what terminals had
to do:
Mobility!
Chişinău, Moldova, 7 October 2011
15
Evolution!
We’ve gone from one
extreme to the other:
Start: all intelligence in the network and
none at the edges “dumb” terminals
Advances in technology enabled
“Bell-heads”
intelligence to migrate to terminals
connected to a “dumb” network
Neither end of the pendulum
swing is ideal …
Chişinău, Moldova, 7 October 2011
“Net-heads”

will be connected
Chişinău, Moldova, 7 October 2011
29
Communications-Enabled Applications
•
Reinvention of services and
applications to support new levels of
network-aware intelligence and
an intuitive interaction experience
•
Achieve through advanced technology
frameworks such as IMS and Services
Oriented Architecture (SOA)
Chişinău, Moldova, 7 October 2011
30
True Broadband
•
•
The communications experience is so
seamless that users no longer have to
consider which technology is being
used to make a connection.
Users simply communicate,
anywhere, anytime from whichever
device is most convenient. Most
importantly, the broadband experience
becomes so economical that the range of
uses exceeds any experience of the past.
