Hello Keith,
2) 3G data instabilities
( Just a quick observation note, no pcap! )
I happened to notice that pinging a 3G handset from
the network side
(default ping: 1 sec internal, 64 ICMP bytes) keeps the connection
"alive" and using 3G data is then a pleasant experience, IM, email,
browsing, SIP call all working nicely. peak max download speed of 16Mbps
was reported at one time by m.speedof.me
Can I ask you to expand a bit more on the topic? Sorry, it's been a while after
you sent the original email.
From where did you perform a ping? From the machine
where GGSN is running?
And that also means that to run 3G PS network now it is needed to make some type
of a service which will ping all the handsets registered, right? (Actually, that
is what I am going to do now while the SGSN isn't fixed by somebody or us)
Thank You!
Kind regards,
Mykola
