That would require some serious voodoo as these are nearly always managed by different entities. So essentially this would keep the problem the same but require wifi base stations and gsm/umts infrastructure to solve this and hide the complexity from the hosts. This isn't traditionally the way the IETF does things.

I was actually expecting that, to get this to work well, you'd need to purchase the 3GPP/802.11 roaming service from a single provider...


I know that this isn't how we typically do things in the IETF. However, I am not sure that we are doing this in the IETF. The only place I know that this particular problem is being considered is in the IEEE (802.21, IIRC). It also seems likely to me that some of the cell phone standards bodies are looking at this (3GPP or 3GPP2, for instance), but I haven't heard of anything specific going on there, have you?

I think that mobile IP could be used for something like this, but not without cooperation from the cell phone providers, right?
