Trends for Service RevenueServices Trends Shaping Evolution

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”


ITU-T

Grouping, Presence, Context Drivers for Enhanced Communication

o 3G and Internet Technologies enable many new services

o How to provide applications & services while taking advantage of the new network capabilities efficiently?

Open Mobile Alliance (OMA)The Leading Standardization Organization for Mobile Service

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, ensuringseamless 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

OMA Service Environment (OSE)New Service Platform Paradigm in Standardization

o The OMA specifies service enablers.o The OMA enablers ! the decomposition

into these components and the interactions between them.

o OMA is defining a new paradigm for an integrated service architecture: OSE (OMA Service Environment)

Future Attractive ServicesMobile Services built over IMS

o IMS provides an integration environment for all communication media, such as Voice, Video & Text.

o IMS realizes the Rich Communication:• 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 CellularWhat is it ?

A form of communication that allows users to engage in

immediate communication with one or more users,

providing a “walkie-talkie”like P2P and group

service.

o The communication is half-duplexo Right-to-Speak amongst different participants is controlledo 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 thesender's voice.

o PoC utilizes the Group Management and Presence enablers to support Group List, Access Lists, and Presence.

Future Ubiquitous LifePersonalization and Context-awareness

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.
