Three Business Models for IMS

• Call control for legacy terminals.
• Business motivation is OPEX saving and necessity
  to replace old technology.
• No expected new revenue or new services, PSTN
  evolution.
• IMS is not only solution for this.
• Mobile standard services.
• Few basic services to be standardized (PoC, IM,
  Presence, Video Sharing, etc.).
• Standalone solutions also possible, proprietary
  solutions available.
• Application based communication services.
• Broadband and Mobile services (multi-access).
• Demand for new kind of thinking, processes and
  partnership. New business models, new earning
  models etc.
• New type of communications (Games, Communities,
  Sharing, Corporate solutions BPN, M2M etc.) .

12
IMS for TeliaSonera

• No single reason, but several disruptions or
  changes in the environment.
• Operators will to migrate networks and services
  into IP-based, to reduce cost level -
  rationalization of production.
• New standalone service opportunities PoC, IM,
  Video Sharing, and enablers.
• Bundling of services in a cost efficient way.
• Creating new environment for applications.
• Convergence services and applications for
  multiple accesses with smaller development costs.
• No need for several service specific platforms.
  Handling various tasks, including charging and
  authentication with one single platform.

Towards Service Centric World

• Todays revenues mainly from access.
• Role of access decreasing.
• Price pressure, cost-efficiency.
• Value moving towards services.
• Services main differentiator.
• Multiple services rather than one killer
  application.
• Shorter service life-cycles.
• Service management and delivery in essential
  role.
• Terminals have key role in ensuring end-to-end
  QoS.
• Terminal diversity challenge.
• IMS as a platform for service
  development.

  specific customer needs.
• Multiple application driven services.
• More complex and fragmented service environment.
• Shorter service life-cycle imposes significant
  challenges to time-to-market.
• Third party application developers are an
  essential source of new services.
• Shorter development times.
• Increased customer understanding.
• Concentrating on niche segments.
• The role of partnership management.
• Technological interfaces.
• Commercial interfaces.

IMS Trialling

• Several end-user trials since August 2003.
• The scope end-to-end end-user trials for IP
  multimedia applications and technologies.
• Different types of applications
• Person-to-person communication.
• Group (community) communication.
• Multiplayer gaming.
• Content sharing, both user created and other.
• Technological setup
• Commercial access network.
• Commercial terminals.
• Pilot IMS platform.
• Pilot applications.
• Pre-installed, OTA delivered and customer
  installed software and configuration.
• Several SIP stack, OS software, application
  releases.

21
Media Community Application - PhotoShare

• Community multimedia communication service for
  smartphones.
• Automatic media (e.g. pictures) exchange amongst
  a pre-determined group of users.
• Customer need for the specified application
  arises from a need to continuously share picture
  information from event of interest with other
  customers.
• First piloted during the Neste Rally event in
  August 2003.
• Limited corporate trials during March-May 2004
  with an improved version.
• Significant input on further IMS activities and
  trials.

22
Main Goals of the Trials

• Develop customer understanding on selected
  application areas, and gather end-users views on
  IP Multimedia applications.
• Collect information about customer behavior in
  the trial environment.
• Work as best current practice/preparation for the
  possible commercial IMS launch.
• Identify technical issues that need to be solved
  before commercial IMS.
• Evaluate, implement and test technical solutions
  for provisioning of IMS-based services.
• Evaluate and test potential charging models.

23
Key Learnings from Customer Trials

• Service usage and customer perception of the
  services, spontaneous ideas.
• Increased customer understanding.
• Radio network issues
• 2G-3G network availability.
• Terminal issues, importance of usability.
• Presence and reachability
• Always on-line necessary.
• Auto-registration needed.
• Battery consumption.
• Application availability at the receiving end.
• Addressing
• SIP address vs. telephone number teluri.
• Provisioning on both the platform and the
  terminal side - application management.
• Need for multi-access.

Need for IMS Interoperability

• IMS is a key enabler for new mobile multimedia
  services.
• In deploying IMS, we need to learn from past
  problems
• Consumers want ubiquitous services not islands.
• Successful services require network effects
  (Metcalfes law).
• Interoperability is a key driver for service
  growth.
• Interoperability is a prerequisite not an
  after-thought.

Interoperability across networks, platforms and
devices is essential to drive service take-up and
ensure commercial success.
26
GSMA SIP Trial Test Campaigns

• Spin-off from the IP Inter-working initiative led
  by Vodafone.
• Trial led by TeliaSonera, who originally proposed
  it.
• SIP Trial is not a paper study focus on
  particular technical and functional aspects
  through hands-on work
• More than 40 companies already participated in
  six test campaigns
• 24 MNOs 13 in APAC, 10 EMEA, 1 Americas
• 11 IMS / network / technology vendors
• 8 GRX carriers
• Individual trial members may agree a campaign
  between them based around a certain SIP based
  service
• Multiple campaigns to be run and allows trial
  members to choose trials to be involved in when
  it suits them
• The ultimate goal is to ensure technical and
  commercial interoperability of IMS-based services
  from day one of commercial service.

27

30
Future SIP Interconnection

  controlled carrier providing routing,
  connectivity and interconnection to other service
  providers through an IPX Proxy
• Session value based accounting and settlement
• Low and predictable latency
• Inter-working protocol conversion (if
  necessary)
• GRX Evolution and IPX specification work in GSMA
  under way

Conclusions

• Services are becoming more application centric -
  third parties are increasingly needed in service
  and application creation and provision.
• Services will be more fragmented. There will be
  multiple services with shorter life-cycles.
• End-customer piloting of new technologies is
  essential for identifying and enabling the
  applications and their commercial take-up.
• Usability of the service from the beginning is a
  key factor presence, provisioning, and always
  online.
• Interoperability across networks, platforms and
  devices is essential to drive service take-up and
  ensure commercial success.
