Abstract:
An apparatus and method for determining a vertical handoff for a node supporting a WLAN and an IEEE 802.16 communication system are provided. Reception of a handoff request message from the node is monitored, an expected change in the total throughput of the WLAN in the case where the node is connected to the WLAN is calculated and compared with zero, and if the throughput change is equal to or greater than zero, the handoff request of the node is acknowledged and the node is handed off to the WLAN.
