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 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

• Peer to Peero Video Chato Interactive gamingo Video sharing (“See what I See”/

“We share”)o Collaboration

3G New Breed of Services

• Complementary serviceso Presence aware serviceso Location aware services

(cont.)

The Solution

• Only IP can do it all and integrate services:o Voiceo Videoo Presenceo IMo Mobileo 3G

• Using:o IMS/MMDo SIPo IPPBXo Softswitches

• Enhanced Messagingo SIP or 3G-324M – Video Mail (VM)o 3G-324M or SIP – Multimedia Advertisemento SIP – Multimedia Messaging (MMS)

• Conversational Multimedia o SIP - Voiceo SIP/PoC – Push-To-Talk (PTT) over Cellular (PoC)o 3G-324M or SIP – Video Telephony & Conferencing

• Video Streamingo 3G-324M (DTMF based video portals) o RTSP (IP TV, surveillance)

• Multimedia Gaming o SIP/JSR-180 (J2ME) o SIP/PoC
