摘要：Much of interest has been involved in integrating UMTS and WLAN networks in order to takefull advantage of the two. In such an integrated network, UMTS subscribers can access to UMTSservices through 3G or WLAN access networks. This is highly desirable because network operatorswill use WLAN hotspots to increase network coverage, while offering subscribers with high-speedconnections to 3G networks. To achieve this goal, a mechanism for service continuity between UMTSand WLAN is required. 3GPP has defined architecture for WLAN access to 3GPP system, butintersystem handover has not been yet investigated. Based on this architecture, this paper proposes asolution for seamless handover between UMTS and WLAN. Results obtained from the implementationof the proposed mechanism on our experimental system are also described
