WiMAX-EVDO Inter-Working Using Mobile IP

WiMAX, a fourth generation wireless access technology, has made significant progress both in the standard forums and with the wireless network carriers. It is important that a WiMAX mobile device has to inter-work with existing third generation access networks, before it is uniquely deployed, to ensure service continuity to a legacy end user. This paper addresses this issue and shows how inter-working can be achieved with EVDO, using Mobile IP. We present a network architecture solution and detailed call flows.
