Ok, terminology; it may also help you to understand the issue.

There's no such thing as an "ip session".   IP is a one-off datagram
protocol.  

What you probably want is for the link not to drop while you have a TCP
connection open on a remote system.  Unfortunately, it's impossible
to detect this, as an open TCP connection normally only generates 
traffic (which can be detected) when it's doing something.
