Good research piece. Definitely something to make people aware of... Thanks for the pointer!


It's interesting to see the actual state transition timing.

I'd like to know how busy the FACH typically is. Could cellular networks be configured so a single UDP packet each way only causes transition to FACH in the first place, and back to idle after 3-6s of silence?

Given the existing chatter that keeps handsets associated with cells, perhaps the network could implement a kind of keep-alive proxy. It requires software changes at both the handset and the network, but would facilitate keep-alive without using any data channel.
