Huawei HSDPA speed problem

**radio_network** · 2014-04-20, 07:44 PM

we are using dedicated ftp server.
From actix, code usage is found ok. CQI also good.

From most of the time channel usage is in FACH 88% . what's the relevant parameter to check for pushing FACH to DCh based on traffic and time
Is there anything i have to do with directed retry, ho timer any help for parameter/command pl.

any explanation for traffic class and THP. and how BE and interactive classes to be configured

any help p.

Increase the Code Max Number for HS-PDSCH from 15 to 30 to increase the OVSF resources and test again.

How come HSDSCH codes be greater than 15?? I don't think so it's possible...Is it?

its possible on the node b level depending on the licence

Watch out when setting the maximum no of 15 HS codes for the Voice/ signalling service; usually 14 HS codes are used to let free 2 SF16 code branches.
Try to test the speed using Handset/ Modem with an unlimited IMSI. What type of scheduler do you have (Round robin? )? Have you checked the load on the NodeB when you tested the speed? what are the maximum throughput speeds at cell level?
