Full Description
ETSI TS 123 234 specifies system description for interworking between 3GPP systems and Wireless Local Area Networks(WLANs). This specification is not limited to WLAN technologies. It is also valid for other IP based Access Networksthat support the same capabilities towards the interworking system as WLAN does. The intent of 3GPP-WLANInterworking is to extend 3GPP services and functionality to the WLAN access environment. The 3GPP-WLANInterworking System provides bearer services allowing a 3GPP subscriber to use a WLAN to access 3GPP PS basedservices.This specification defines a 3GPP system architecture and procedures to do the following: Provide Access, Authentication and Authorisation (AAA) services to the 3GPP-WLAN Interworking Systembased on subscription. Provide access to the locally connected IP network (e.g. the Internet) if allowed by subscription. Provide WLAN UEs with IP bearer capability to the operator's network and PS Services, if allowed bysubscription. Provide WLAN UEs with IP bearer capability to access IMS Emergency calls for both UICC and UICC-lesscases.The interworking between 3GPP systems and Wireless Local Area Networks (WLANs) functionality in thisspecification is replaced by the functionality in 3GPP TS 23.402 [40].
No further changes to this specification are intended. If any future evolution of the procedures in this specification isnecessary, it should be documented in other specifications.
