Fixed-mobile convergence has been growing in importance for several reasons, among them a general demand shift to wireless access, but also because of growing preferences for a more unified user experience and broadband economics.
On the latter score, the key issue is simply that wireline broadband is more economical than wireless broadband, and likely always will be. So to the extent that end user demand shifts to wireless devices, service providers must find ways to offload traffic to the wired network.
.
On that score, KT Corporation of Korea, TelcoWare, and mobile broadband gateway developer Stoke say they have succeeded in implementing seamless network handover between 3G, Wi-Fi and WiMAX networks, even when users are moving at speeds of 60 kilometers per hour.
Seamless handoff will be key for mobile providers trying to automatically shift access to any available wired broadband network, and to enhance seamless handoff back to the mobile network.

can i get more technical details about this.
This is an example of lots of work going on to ensure session handoff between cells. See the WiMAX Forum site, for example.
It would be really interesting to get more technical details about this. Are they using 802.21?
Maybe they are implementing the 802.21...
