An > example of WLAN/GPRS card can be found here: > http://www.nokia.com/phones/nokiad211/ these sound like useful categories. however, for categories #1 and #2 there would need to be different requirements depending on whether or not the device had an external interface to which one or more other IPv6 hosts could be attached. JWi: Thanks for your opinion! This is a relevant point to think about - however, a typical case in 3GPP architecture would be connecting a laptop computer to the mobile terminal using PPP(v6). as for category #3, I'd focus on defining the requirements of the network interface that is seen by the laptop, rather than the requirements of the laptop itself. presumably the laptop is a normal IPv6 host and doesn't have unusual requirements. JWi: Good point as well. Certainly, laptop is a "normal IPv6 host" and does not need special treatment. We could write some clarifying text about the laptop (network interface) and leave the laptop IPv6 functionality to be defined in a separate specification (a generic IPv6 host draft)?
