1/ Connect your phone to your Computer, so that it acts as a Modem
2/ Attach your computer to your network using the Phone connection
3/ open Windows Command Prompt
4/ type “ping ip_address_of_ggsn”
check the delay of the first ping (estabilishment of TBF)
check the delay of next pings (tbf already established)
I don’t think so. From GGSN, you can try to ping the MS, so that will tell you the DL latency…
But there are no statistics about this, as far as I know. I’m not a core network expert though…
