Trends for Service Revenue
Services Trends Shaping Evolution
ITU-T
o Multimedia
• Services are becoming more visual as the phones will be able to
capture and display pictures, graphics and video
• Rich Service Creation
o Contextual and Personal
• communication networks ! know more about users !
influence the services users receive
• gather more information about others ! share more
information about ourselves with others
• Context awareness leads to higher degree of personalization !
requirement for successful new services
o Social and Community Focused
• People are social animals. We build social networks
• Modern networks and services offer the chance to build services
that allow users to interact in groups, as they do in the “real
world”

Open Mobile Alliance (OMA)
The Leading Standardization Organization for Mobile Service
ITU-T
o Brief history
• formed in June 2002 by 200 companies (now over 400 memberships)
• major parent body was WAP Forum
o
The Mission of OMA is to grow the market for the entire mobile
industry by removing barriers for global user adoption, ensuring
seamless application interoperability, while allowing business to
compete through innovation and differentiation.
o OMA aims for a uniform service architecture for:
• Compelling new mobile services
• Interoperability between infrastructure, devices and services
• Healthy competition
• Less market fragmentation
• Lower cost in service development
• Faster global service deployment
• Enriched user experience across service providers

Future Attractive Services
Mobile Services built over IMS
ITU-T
IMS provides an integration environment for all communication
media, such as Voice, Video & Text.
o IMS realizes the Rich Communication:
o
• Real-time Multi-media,
• Group and community centered services
o
Example IMS Services:
• Instant Messaging, Presence List
• Rich Voice Call (Presence based call forwarding & barring,
voice enabled games, bearer change, etc.)
• Group Text Chatting
• Live Goals: Video Streaming Service (let your phone watch..)
• Phone trader: Automatic call set up when stocks hit their sell
price
• Push-to-Talk
• Multimedia Multiparty Conferencing (e.g. Multiparty Games)
• Personalized Information Services

Push-to-Talk over Cellular
What is it ?
ITU-T
A form of communication that
allows users to engage in
immediate communication
with one or more users,
providing a “walkietalkie”like P2P and group
service.
Member A
Wireless Network
Member E
Member B
Member D
Member C
o The communication is half-duplex
o Right-to-Speak amongst different participants is controlled
o The receiving participants hear the sender's voice either by Auto
Answer without any action on their part, or by Manual Answer, i.e.
being prompted/alerted and accepting the call before hearing the
sender's voice.
o PoC utilizes the Group Management and Presence enablers to
support Group List, Access Lists, and Presence.

Ongoing Service Developments in OMA
over IMS and beyond (selection)
ITU-T
o Messaging
• Ideas to bring IM, PoC, and other messaging enablers together
o Content-related
• Content Screening
— Terminal-based framework
— Categorized content screening on server and terminal side
• Dynamic Content Delivery
— Periodic/on-demand content push
• Digital rights Management
o Delivery Mechanism
• Mobile Broadcast

Future Ubiquitous Life
Personalization and Context-awareness
ITU-T
o Group Communication over IMS enlarges the possibilities of
communication but requires more personalized and context-aware
service.
• Individual participants have different preferences and can be in
different situations regarding time, location, activity etc., which must
be taken into consideration.
o Personalization and Context-aware service are key technologies.
• E.g. based on IMS user profile information.
o Context-awareness as a presence-enhanced service.
• Context, as background information, to adapt the service to the user’s
situation can be fed by the IMS Presence Service, with emerging sets of
sensors like GPS, RFID, etc.,.
• Application can be a watcher of its serving users to tailor services it
offers according to individual users’ presence information.
