I wanted to know if there is a way I the client could know if the server (mobile cell) on the other end still has connection with me.
I do so far LCP, CHAP and then IPCP and then sit there hoping users from other end of the world will send me web (HTTP) querries :)
However after long periods of inactivities I have noticed my dongle becomes unresponsive. Well I do a http request after long periods of inactivity, the lil webserver on micro will no longer respond. Well infact the dongle does not receive any data to start with. So my conclusion is that the mobile network operator on the other end has assumed I have gone offline?
So is there a way I could perform "I am alive" or "Are you alive" games with the remote end (mobile network) once in a while to let it know I am still hooked on during periods of inactivity?
I think also the network operators disconnect 3G internet during times of high demand or 4hr session etc, right?
