What about the laptops with built-in 3G/4G or using UE as a modem?I don't know much about how that interface usually goes (PPP or DHCP+Ethernet), but sure laptops could be modified e.g. by driver updates(?). But then I don't know about laptop OS'es capability for doing DHCPv4 on-demand (I would expect the laptop OS'es would rather try to keep IPv4 address allocated all the time).
There's traditional tethering vs the cpe approach, at the point where the handset simply acts a a router, maintenance of the pdp context(s) and indeed the whole air interface is solely at the discretion of the handset/router, and the PC is invisble in that equation.
We should make this distinction (laptops, UE-only). Laptop OS's do support DHCP obviously. -RajeevYes, but this is *may* per 3GPP TS 23.401. Your draft should be moreexplicitin telling that the percentage of host population that actuallyimplements the*may* part is unknown for time being.I would rather say that DHCP is optional but a provider may require it to be used.Right, consumers often has this power over producers..
