Adroid: GSM connection does not timeout even after the device goes to sleep

+2 votes

We have some native code that was doing a xmpp ping every 12 minutes, and if a ping didn't happen til 5 minutes after the device went to sleep, the GSM connection would silently drop.
If we change our ping interval to something like 4 minutes, the GSM connection will stay up even after the device goes to sleep.
My question is are the rules for how the GSM radio and sleeping documented anywhere?Are the rules changed by Manufacturer or by Carrier?

What network an iPhone is connected to (LTE vs GSM). How to confirm this ?

With the release of iOS 6 and iphone-5 I'm trying to figure out how my app can know if the phone is in LTE mode vs GSM mode.

I haven't seen any updates to the Reachability API which can give whether it is connected to Wifi vs WWAN but I need to know what kind of WWAN connection it is.

Any ideas?
