“…When connection is loose, a distinct path is supplied for 3G traffic, therefore WLAN traffic is not passed through the 3G network and routing to the Internet is through the WLAN gateway. Thus, various protocols for accounting and authentication might be employed by WLANs and 3G networks [12,13]. When connection is tight, a WLAN is linked to the 3G network in the same way as other radio access networks.…”

Abstract-Current trends show that UMTS network and WLAN will co-exist and work together to support more users with higher data rate services over a wider area. However, this integration invokes many challenges such as mobility management and handoff decision making. Vertical handoff is switching process between heterogeneous wireless networks in a 3G/WLAN network. Vertical handoffs often fail due to the abrupt degrade of the WLAN signal strength. In this paper, proposed a new vertical handoff method for to decrease the number of signaling and registration processes, to examine the Special conditions such as WLAN black holes and to eliminate disconnecting effects. By estimating user locations related to WLAN position, interface on-times will be reduced which makes the power consuming of the system decreased. To indicate the efficiency of proposed approach the performance and the delay results are simulated.

This paper introduces a novel vertical handoff method in which the number of signaling and registration processes is lowered as a result of reduced utilization of home agent and correspondent nodes while users are mobile. Throughput performance of the integrated network is improved by reducing handoff delays and packet losses. We also decrease the system energy by estimating user locations in comparison with the WLANs to decrease interface ontimes. Performance and delay results are presented to demonstrate the effectiveness of the proposed scheme.
