How can we make this

Blending User Devices
For communication and messaging services
ITU-T
o PC, phone(s) and PDA end up being different
user interfaces of the same network-based
application
o Common, network-based directory for
• Phone numbers
• Buddies & presence
• Email address book
• All applications
o Unified, network-based, user profile applying
to all terminals
• E.g: set presence location, ( call routing
preferences), etc., on either of the terminals
and apply to all
• Phones (and PC) presence ( call routing
preferences), automatically updated
• PC presence info automatically updated based
on phone location
Increase ARPU: the blended handset is a friendlier handset

Blending User Devices
For communication and messaging services
ITU-T
o User selects a person to call on the PC from a
network-based directory
o Click on the person and set up a call between
the user’s mobile phone and the callee
9
ITU-T
Adding the desktop into the
picture
o Does not necessarily require providing wireline
connectivity
• Interaction is at the service level
o User fidelization
• Once the user gets used to the wireless-based
services he will want to use them even when the
notebook is in the docking station
• Vice versa, if the user gets used to the services
in the office, he will be more willing to use
them when on the road
o SMEs may outsource PBX services to the operator for
service harmonization between external and
internal calls
o Big corporations will own their infrastructure and
interface it with the operator

Just one address to reach the
ITU-T
user
Application-specific
Logic
Call processing logic based on
screening rules (E.g. reject video
calls if not in buddy list/address
book), Presence, location, user
profile, calendar, preferences

GWs may be needed to interface
with legacy infrastructures
Operator becomes the ultimate
single point of contact for the user
Just one phone number will always
be used to contact a person
Network takes over the complexity of reaching the user

Making it real
Summary
ITU-T
o The Operator becomes the ultimate single
point of contact for the user
o Single phone number/address will always be
used to contact a person
o Receiving party then decides where to answer
the call

Making it real
Summary
ITU-T
o Can include ousourced PBXes for SMEs and
voice VPNs for big corporates
• Service may be
• VoIP to the Etherphone
• VoIP to the corporation’s edge – then be converted
into TDM via a GW
• VoIP to the operator’s edge – then converted into TDM
and carried by a wireline TDM operator
16
Making it real
ITU-T
Further considerations
o Blending PCs, wireline phone(s), wireless
phone(s) and PDAs turns the presence info into
the ultimate info on the availability of the
person
o As the operator receives all the the calls for
the person:
• it can provide a common busy (or free,
according to user preferences) tone, regardless
of where the user answers
• it can automatically update the presence to
“on the phone”
• it can associate a complex call screening
profile to the user presence states

o One person uses one“address” for many services, many
devices, many accesses
• User is paged based on his preferences & presence info.
• Same address can be used on the same device from
many locations
• Same address supports Voice, Video or Text (IM or Email)
and the enhanced messaging-based services
• Generic addresses can be shared by multiple users
o NGN bridges the ultimate gap in person-to-person

Access Independence &
WLANs
o Access independence provides service ubiquity
throughout WLANs and Corporations
• Presence information will provide info on the specific
device the user is logged in on, allowing for intelligent
call routing
o Wireless operators are best positioned to leverage this to
become the single point of service contact to the
subscriber
• Wireless Operators will be the only stakeholder with
direct access to key information such as the user’s
location
• Wireless Operators also hold a secure user identity
thanks to Smartcard (SIM)-level authentication, credit
information (where allowed)
• Wireless operator will hold the user’s universal address
and receive the call/service invocation.

ITU-T
Beyond the one service-one
platform paradigm
o Generalised session
establishment protocol.
• Any type of session
• Any end-point
o Integration-Interaction
• Session comprised by
many types of media
(integration)
• Easy added or removed
of each session
(interaction)
o Simplification

The SIP-Based Corporate
Extranet
o Most corporate processes are dealt with custom
applications
• Applications are available to deal with most of the
common internal processes
• Applications have now been developed to allow for
extranet communication to wired users of most of
the relevant info
o Wireline extranet has standardized on HTTP/WWW to
avoid distribution of custom clients
o Will WAP be the wireless equivalent ?
WAP shown wireless paradigm is different from wireline Cannot just port all web-based services to a smaller screen
23

ITU-T
Drivers
o Mobile users want immediate access to the information.
Don’t want to:
• remember and type an URI/URL
• click on several links before getting to the info
• remember and type a username and password
• remember and type any further process codes to get to
specific instances of applications
• e.g. the "delivery code" to track a parcel
• remember and type phone numbers
• install custom application on their phone, possibly
requiring connecting to the PC, or a complicated
network-based procedure.
• especially if they will use that app just occasionally
• repeat a lengthy access to info to know if it changed
• much better to see the desired info automatically
updating itself
Can we think of a standard, general purpose application
execution environment meeting all the “don’t wants” ?
