Topics
• Challenges and complexity
• Customer perspective
• Service provider perspective
• 3G new breed of services
• Solutions & protocols
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
o Introduces new challenges
o Requires knowledge of a wide range of
technologies
How can the customer use it? What about the user
experience?
The Complexity
• Convergence
o
Access (XDSL, Cable, Wi-Fi, WiMAX, 3G, …)
o
Networks (CS, PS, radio)
o
Device (per technology vs. cross technology)
o
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)

Customer objective
(cont.)
• Works on multiple networks (enterprise, home,
home office, cellular)
• Coverage and seamless transitions (roaming and
handover) between networks
Service provider objective
Increase ARPU
• Providing mobile access at home or in the office to
increase usage by customers
• Poor coverage at a subscriber’s 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)
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

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
