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 challengeso Requires knowledge of a wide range of
technologies
How can the customer use it? What about the user experience?
The Complexity
• Convergenceo 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)

The real developer challenge…
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
Customer objective
• Identical user experience• Additional services:
o Simplify call forward between wireline and wirelesso Alarm systemo Faxo Mobile stations to act as cordless phones when at
home, calls idle phones when busyo Intercom featureo Multimedia services
• One consolidated bill• Reduced cost, time, and hassle
Customer objective
• Works on multiple networks (enterprise, home, home office, cellular)
• Coverage and seamless transitions (roaming and handover) between networks
(cont.)
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
• 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
3G New Breed of Services
• Enhanced Messagingo Video Mail (VM)o Advanced Multimedia Advertisemento Multimedia Messaging (MMS)
• Conversational Multimediao Push-To-Talk (PTT) over Cellular (PoC)o Push to Show/ Push to Viewo Videoconferencing for business or
private use “on the go”
3G New Breed of Services
• Video Streamingo Live video broadcasting – TV on the
goo Video On Demand (movies, news
clips) - VODo Video session archiving serviceso Playback & recording
