Background-1 Promotion Promotion Phase III Phase I, II FMC mVoIP Multi- screen FMS mIPTV Unified Single IP Network MMOIP Interworking Wired & wireless IPTV 2010 DCATV MMOIP Define Concept VoIP 서비스 개발 2004 VHO Femto IMS-SC QoS DOCSIS FTTH QoS IMS OpenAPI From 2008, through the BcN project has promoted mobile convergence 21-10-0224-00-srho

Demand for broadband data Background-2 Demand for broadband data Data rate Smart phone: - Bandwidth < 1Mbps - Screen: 3”/ QVGA Complementary Network (Island Coverage) Laptop: - Bandwidth ~ 10Mbps - Screen: 15” / VGA LTE/WiBro/WiFi WCDMA(HSPA) Main Network (Full Coverage) CDMA/1X/EVDO IPTV: - Bandwidth > 10Mbps - Screen: 40” / Full HD Seoul Metropolitan Suburban Major Cities Rural Need to select a RAT and to manage resource effectively in heterogeneous mobile network environments Need to supply same user experience and seamless services 21-10-0224-00-srho

Overall service concept To provide mobile internet access services both HSPA and WiMAX environments with dual mode terminal(USB-dongle type) Supports automatically switching-over both direction Supplementary video clip for describing service concept 21-10-0224-00-srho

Overall architecture The implemented interworking architecture supports inter-technology handover between 3GPP and WiMAX (both direction) Use MIH, PMIPv4(WiMAX domain) and CMIPv4(WCDMA domain) 21-10-0224-00-srho

End user equipment (Terminal) USB dongle type modem(WiMAX & HSPA) Connection Manager in client 21-10-0224-00-srho

Handover Preference 3types preference – client set the modes WiMAX preferred mode WiMAX only mode or WCDMA only mode (no handover occurred) 21-10-0224-00-srho

Handover latency Show Video clip WCDMA to WiMAX < 10s WiMAX to WCDMA < 40s Supplementary video clip to show WCDMA to WiMAX Supplementary video clip to show WiMAX to WCDMA 21-10-0224-00-srho

MIH deployment status Field trial services (1. Sept. ‘10 to 30. Nov. ‘10) 40 trial subscribers 10 test engineers Expect Subscriber’s locking (provides value to use any interfaces with one account(billing)) Start position to be extended multi-devices with one accounting (multiple interfaces to multiple devices with one accounting product) Data off-loading for a 3GPP network, to WiMAX and WiFi Will survey with questionnaire to trial subscribers after end of trial services Satisfaction Necessity Willing to use and Willing to pay What services are apt to using VHO tech. (Streaming, VoIP, Video Conferencing etc.) 21-10-0224-00-srho

Conclusion VHO tech. market positioning for mobile operators Manage VHO accounting and performance efficiently in the view point of mobile operators Data off-loading will be a practical target (based on some operator case) feature phone 12.4M, FMC phone 12,000, iphone 87,000, smart phone 31,000, dongle 35,000 3G data traffics has increased (+420GB, that is 9.7% of total traffics) 21-10-0224-00-srho
