Service Evolution with IMS
spacer
IMS will shift the focus of mobile services from only voice, one-to-one services to hybrid multimedia services that blend voice, messaging and video. This will switch the delivery of services from a network centric approach, where services are determined by network architecture, to a customer centric delivery that allows users to determine how they want to communicate.

IMS will also break down the access barriers that have existed for communication services. With service delivery shifting to the IP network, services become independent of the access medium. So users will be able to have the same services from their mobile phone, wire line or PC.

New Service Paradigms

Within the realm of digital services, clear trends are shaping the direction that service growth is taking. These are:
  • Increasing use of multimedia - Devices now able to capture and display pictures, graphics and video allow users to create and share their own content and use a larger number of media for communication.
  • Contextual and Personal - Users can now share more information about themselves and know more about other users and this trend of sharing personal and contextual information is growing.
  • Social and Community Focused - People are social animals and build social networks. Communication is more often than not a group activity and placed in context by the community background.

These trends are shaping the direction that user expectations and services will follow and it is these kinds of services that IMS is particularly able to target.

IMS will introduce new elements to the user experience that will make it more intuitive and in line with how people communicate, face to face. The traditional one-to-one model will be eroded as IMS brings in group services that allow users to quickly and easily set up small groups for voice, text and multimedia services.

For end users, the mobile experience until now has been a fragmented experience. While users now enjoy a large number of mobile services their phones, these services are separate and distinct from one another and users have to choose one over another. Services have continued to be built created to suit all with very little real customization to suit individual needs.

IMS, as platform that makes available service enablers for use in services, will allow a more integrated mobile experience to be created. One very obvious example of this is Presence which lets users share information about themselves such as whether they are free to talk or their emotions with others in real-time. Presence is one of IMS’s common enablers and can be integrated across all services by implementation in the address book. Whenever, a user wants to use a service they can launch this by choosing members from their address book that are on-line and free to talk.

With IMS there is an opportunity to deliver to users a larger number of services while making the overall experience simpler and more intuitive.

For network operators and services providers IMS offers more options and tools for creating services and at the same time brings an open standardized approach to service creation. The result of this will be that operators, service vendors and service operators will be able to bring new services to market in shorter cycles and with less investment.
