  12. Throughput of ring network 1 Gbps Handover time 200ms Throughput of access network 100 Mbps Metroplitan Mobile Ring Network • Goal • Develop large scale micro mobility support in metropolitan area. • Feature • Flat ring architecture for decentralizing routing information ( no bottleneck nodes ) • L2 independent • Achievements • Fast handoff implementation • Performance evaluation • Load balancing in extended WLAN access points 100,000 nodes registrations / LMA

  13. Internet MNb MNc Metropolitan Mobile Ring Network binding list MNa IPa MNb IPb IPx CN IPx IPa MAP2 MAP1 IPx IPa (IPb) GW MNa (IPa) MAP3 MAP4 (IPc)

  14. (3) FH request [MAC=MACmn, IP=?] (4) FH reply [MAC=MACmn, IP=IPmn] binding list oLMA nLMA (2) FH notification oAP nAP (1) Association MN FH request: MN’s MAC address FH reply: MN’s IP and MAC addresses Fast Handoff Process • MN moves from oAP to nAP • nAP sends FH notif to nLMA • nLMA sends FH req. • When oLMA receives FH req, oLMA sends FH rep with MN’s IP address and oLMA’s MAC address. • When nLMA receives FH rep, nLMA registers MN’s IP and MAC addresses to binding list. • nLMA starts transmission MN’s packet to MN.

  15. Video phone Video phone Voice phone Voice phone Cross-Network Services and Mobility Support • RAN-overlaid MIRAI • Enables communications using the optimal wireless system based on user presence, preferences, and network status. • Separates “data paths” and “signaling path” (any radio network can be chosen for the signaling path). • Conserves power by switching off all unused RAN interfaces Network Functions -Basic Access Signaling -Mobile IP Home Agent -SIP Proxy Home Network A Presence Home Network B WLAN The Internet Call button - Video phone - Voice phone - Voice mail WLAN 3G PHS Handover from WLAN to 3G Main Window 2G WLAN Handover from PHS to WLAN Data path Network Status -hot: available -cold: not available -BAN: signaling network -RAN: data network Available Networks - Ethernet - WLAN (11a / 11b) - 3G (WCDMA) - 2G (cdmaOne / PDC) - PHS (AirH” / @FreeD) Signaling path MUT-A MUT-B MUT Prototype(Multi-service User Terminal) Personal Information Window Partner Information Window

Hospital Emergency call by mobile phone with video-recording function Based on the video with the emergency call and data from theambulance, the hospital mayinstruct proper treatment orprepare for a surgery. Injury or health condition can be recorded on the scene by handset to send an accurate picture to paramedics. 54Mb/s 11Mb/s 384kb/s Once the ambulance enters wireless LANcoverage, the stored data may betransmitted to the hospital. High-definition still-image data etc. may be transmitted High-definition video data etc. may be transmitted. Fire Station On the ambulance, a patient’s data is constantly recorded, including pulse rate, heart rate, electrocardiogram, blood pressure, condition (video) and injured part (video), etc. to be stored in the on-board server. Of all the stored data, pulse rate and anyother data of greater urgency is constantlytransmitted by W-CDMA to the hospital.
