• Challenges and complexity
• Customer perspective
• Service provider perspective
• 3G new breed of services
• Solutions protocols

3
The Challenge

• Hybrid solutions of WiFi/WiMAX and 3G/GSM enabled
  devices - next step in Mobile Broadband evolution
• From a consumer perspective, these technologies
  should operate seamlessly
• This hybrid of technology convergence
• Introduces new challenges
• Requires knowledge of a wide range of technologies

How can the customer use it? What about the user
experience?
4
The Complexity

• Convergence
• Access (XDSL, Cable, Wi-Fi, WiMAX, 3G, )
• Networks (CS, PS, radio)
• Device (per technology vs. cross technology)
• Service (Service per network vs. unified
  services)
• Technologies (DMH, UMA, FMC, IMS)
• Mobility (network independent services)
• Coverage (roaming, handover, handoffs)
• Usability (How can customers use it?)
• Services (Quad play voice, video, data, mobile)

The Broad Picture - WiMax Convergence
The real developer challenge
6
Customer objective Preserve existing services

• Telephony
• Emergency call
• TTY
• SMS, MMS
• Data/ Internet
• Location Service
• Supplementary Services (e.g. Caller ID, one
  voicemail, 3-way conference)

• No change in phone number
• Incoming calls follow me
• Outgoing calls have same caller identity
• Synchronized address book
• One dial plan
• Voice quality
• Security

7
Customer objective

• Identical user experience
• Additional services
• Simplify call forward between wireline and
  wireless
• Alarm system
• Fax
• Mobile stations to act as cordless phones when at
  home, calls idle phones when busy
• Intercom feature
• Multimedia services
• One consolidated bill
• Reduced cost, time, and hassle

8
Customer objective
(cont.)

• Works on multiple networks (enterprise, home,
  home office, cellular)
• Coverage and seamless transitions (roaming and
  handover) between networks

9
Service provider objective Increase ARPU

• Providing mobile access at home or in the office
  to increase usage by customers
• Poor coverage at a subscribers home or office
  ranks as a primary reason for subscriber churn
• Keep customers on their networks where ever
  possible to avoid roaming or other related
  charges while on other networks
• Seamless integration of additional services (e.g.
  multimedia)

10
Service provider objective Services

• Quad play services to its customers
• Bundled services from its inventory of services
• Enter the mobile loop market by providing
  converged fixed/mobile services
• Customer experience the same or better than that
  offered by competing mobile service providers
• All services to perform as well, independent of
  the access/ network including call-setup time,
  voice quality, data rates, etc.
• Use existing core network to deliver all
  services, including authorization and billing,
  for licensed and unlicensed access

11
3G New Breed of Services

• Enhanced Messaging
• Video Mail (VM)
• Advanced Multimedia Advertisement
• Multimedia Messaging (MMS)
• Conversational Multimedia
• Push-To-Talk (PTT) over Cellular (PoC)
• Push to Show/ Push to View
• Videoconferencing for business or private use on
  the go

12
3G New Breed of Services
(cont.)

• Video Chat
• Interactive gaming
• Video sharing (See what I See/ We share)
• Collaboration

13
3G New Breed of Services
(cont.)
