Trends for Service Revenue

Services Trends Shaping Evolution

• Multimedia
• S

ervices are becoming more visual as the phones will be able to capture and display pictures, graphics and video

• Rich S

ervice Creation

• 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

• S
• cial 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

• Brief history
• formed in June 2002 by 200 companies (now over 400 memberships)
• maj or parent body was WAP Forum
• 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.

• 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 Environm ent ( OSE)

New Service Platform Paradigm in Standardization

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

into these components and the interactions between them.

• OMA is defining a new paradigm for an

integrated service architecture: OS E (OMA S ervice Environment)

RPC CORBA/ Java Web Services

IN/ CSE platform IP GPRS / UMTS GSM ISDN Parlay X

SIP Interface INAP/CAP Interface OSA / Parlay Interface

OMA OSE OSA /Parlay gateway IMS platform

OMA analysis how OSE and Parlay/OSA architectures could be integrated and how components implementation/ realizations coexist for OSA/Parlay, Parlay X Web Service and OSE.

Future Attractive Services

Mobile Services built over I MS

• IMS

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

• IMS

realizes t he Rich Communication:

• Real-time Multi-media,
• Group and community centered services
• Example IMS

S ervices:

• Instant Messaging, Presence List
• Rich Voice Call (Presence based call forwarding & barring,

voice enabled games, bearer change, etc.)

• Group Text Chatting
• Live Goals: Video S

treaming S ervice (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 S

Push-to-Talk over Cellular

W hat 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.

• The communication is half-duplex
• Right-to-S

peak amongst different participants is controlled

• 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.

• PoC utilizes the Group Management and Presence enablers to

support Group List, Access Lists, and Presence.

Future Ubiquitous Life

Personalization and Context-aw areness

• 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.

• Personalization and Context-aware service are key technologies.
• E.g. based on IMS

user profile information.

• 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 S ervice, with emerging sets of sensors like GPS , RFID, etc.,.

• Application can be a watcher of its serving users to tailor services it
• ffers according to individual users’ presence information.
