HSDPA about Throughput is very low 15kb/s

Hi

Have you checked HSDPA parameters setting in the RNC? and the PHY channel/scheduling in the NodeB.

Hi,

No big findings.
What can be seen are most of the time is used QPSK and small TB size as DTX around of 50% which is strange taking into account good radio conditions.
I would suggest you following actions:


1) Start downloading and use LMT IMSI trace and Wireshark in parallel.
2) Try the test with another data modem.
3) Use internal server connect directly to the GGSN.
4) Just in case double-check your Iub configuration.

From LMT trace and wireshark you can find probably where the problem comes from.

Wish you success.

And something totally apart from your case. I noticed that the cell 616 in your RNC1 use RSCP for reselection. I wouldn't recommend it. In my opinion it should be set to Ec/No but could be operator strategy as well in specific cases...just mention it.
