doc.: IEEE /162r0 Submission March 2003 Stephen McCann & Max Riegel, SiemensSlide 4 Is interworking inside the scope of Yes, it defines the functions of a public access Wireless Ethernet interface. Yes, similar approach to TGf : signalling to enable communications between access points.

doc.: IEEE /162r0 Submission March 2003 Stephen McCann & Max Riegel, SiemensSlide 8 Interworking : What ? Seems to be a lot of interest here. What can WNG do ? –Look at current functions/interfaces –What additions are required to meet W-ISP & Cellular requirements (3GPP and 3GPP2) –Come up with a model which matches the external networks of all these guys.

doc.: IEEE /162r0 Submission March 2003 Stephen McCann & Max Riegel, SiemensSlide 9 What do you mean ? requires some work in the access network to define external interfaces TGe, TGf, TGi and TGk have started to do this already with functions. Need to look at Accounting as mentioned yesterday Let‘s start by looking at issues in the 3GPP requirements document. Must also address W-ISP and 3GPP2
