November 2019 doc.: IEEE 802.11-19/2046r0 Abstract Current WLAN access network can not access to 5G core network. So the station can not provide dual access of 5G and WLAN using 5G core networks. Therefore, it needs WLAN interworking to 5G network. The initial technical draft report on WLAN interworking to 3GPP 5G network describes the interworking reference model and two types of interworking, and defines the necessary functionalities and specific procedures that enable WLAN access networks to interwork with 3GPP 5G network for data throughput improvement and QoS management. Submission Slide 2 Hyun Seo OH (ETRI)
November 2019 doc.: IEEE 802.11-19/2046r0 WLAN Interworking Functional Model These red coloured Y1, Y2, Y3 and NWu interfaces are in the domain of WLAN and may be provided in STA and WLAN access network. The other reference interfaces are referred to 3GPP core network. Submission Slide 3 Hyun Seo OH (ETRI)
November 2019 doc.: IEEE 802.11-19/2046r0 Modification Part in WLAN Domain Functional entities to be modified - TEC (Terminal Control) and Access Network Control(ANC) function need to provide NWu communication protocol and QoS mapping Signal interface to be defined - Y2 interface : wireline communication between WLAN access data path and N3IWF - Y3 interface : NWu communication protocol Submission Slide 4 Hyun Seo OH (ETRI)
