scope:

This document studies the feasibility of interworking between 3GPP systems and Wireless Local Area Networks (WLANs). This document identifies and describes:

- Scenarios for 3GPP - WLAN Interworking

- 3GPP - WLAN interworking service requirements

- Guidelines for standardisation of 3GPP-WLAN interworking

The document 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 report 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.
