ITU-T
For communication and messaging services o o o
PC, phone(s) and PDA end up being different user interfaces of the same network-based application
Common, network-based directory for
• Phone numbers
• Buddies & presence
• Email address book
• All applications
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

For communication and messaging services
ITU-T o o
User selects a person to call on the PC from a network-based directory
Click on the person and set up a call between the user’s mobile phone and the callee

o o o o
Does not necessarily require providing wireline connectivity
• Interaction is at the service level
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
SMEs may outsource PBX services to the operator for service harmonization between external and internal calls
Big corporations will own their infrastructure and interface it with the operator

Summary o o o
The Operator becomes the ultimate single point of contact for the user
Single phone number/address will always be used to contact a person
Receiving party then decides where to answer the call
• Mobile phone(s)
• PDA
• PC
• Wireline phone
15

ITU-T
Summary 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

ITU-T
Further considerations o 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
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 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
NGN bridges the ultimate gap in person-to-person communication

ITU-T o 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
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.

Generalised session establishment protocol.
• Any type of session
• Any end-point
Integration-Interaction
• Session comprised by many types of media
(integration)
• Easy added or removed of each session

Simplification

o o 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
Wireline extranet has standardized on HTTP/WWW to avoid distribution of custom clients
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 o
Drivers
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” ?
