Decisions for vertical handovers from WWAN to WMAN or WLAN access technologies are very challenging issue because it needs to deal with different radio access networks and make smart decisions for vertical handover calls between them. Especially the decisions for vertical handovers from WWAN to WLAN hotspots in heterogeneous mobile and wireless networks are very important because they impact the QoS of the mobile users, especially when they are using real-time services. In this paper we propose vertical handover decision algorithm from WWAN to WMAN or WLAN networks based on the load of the networks, speed of the mobile users, bandwidth and priority of the sessions of the mobile nodes. We use the IEEE 802.21 standard as a layout for implementing the algorithm. The results show that the proposed algorithm reduces unnecessary vertical handovers from WWAN to WMAN or WLAN access technologies and optimizes the load of the networks, improves the distribution of the call arrival rates and blocking probability of the vertical handovers from WWAN to WMAN or WLAN.
