This TR studies the feasibility of interworking between 3GPP systems and Wireless Local Area Networks (WLANs). This TR identifies and describes:
Scenarios for 3GPP - WLAN Interworking
3GPP - WLAN interworking service requirements
Guidelines for standardisation of 3GPP-WLAN interworking
The TR includes a number of different scenarios of 3GPP-WLAN interworking ranging from common billing to the provision of services seamlessly between the WLAN and the 3GPP system. In addition, 3GPP-WLAN interworking feasibility study includes the analysis of a number of environments where both the 3GPP system and WLAN may be deployed. Finally, this TR outlines some of the different WLAN technologies that may be interworked with 3GPP systems.
It is beyond the scope of 3GPP to develop new system functionalities for WLANs that are not interworking with any 3GPP system functionality.
