    Integration of UMTS and WLAN can be performed at different levels. A promising interworking approach embeds the WLAN into the UMTS radio access network. It provides additional license-free capacity to operators and good vertical handover performance. As the WLAN is attached directly to the UMTS radio resource manager, this approach allows possibility of collocation of resource managers of both networks. Common radio resource management allows more efficient use of resources and facilitates vertical handover management. The paper discusses this issue for two architectural options for WLAN-UMTS integration at radio access level.
