Handling "Limited Up" modem state | Telit Cinterion IoT Developer Community

In GPRS TCP/IP connection what is the correct way to handle "Limited Up" modem state?

(Internet connection is established, but temporarily no network coverage)

Do I need to constantly pull for "Up" state to resume?

Do I need to issue a Service/session close and open when I got "Up" state?

Or do I only need session open when state reaches "Down" then "Up"?

Can I get away without network state polling? (registered, searching..)

Is there a good flow diagram about connection fallback/escalation handling?

My particular modem is BGS2-W, but I think this is generic.
