Dear Experts ,

Need your support to find out solution about Latency issue .

I have tested Ping from Data card and UE in 5 diffrent ping packet type (32,100,200 and so on) , Below are my observation

1. DATA CARD - Channel type FACH for firts four test (32,100,200,300 and 400 byte ping) , DCH for 500 Byte.
2. UE W995 - Channel type DCH for all scenario .

Dlrlcbufferupswitch/ ULrlcbuffupswitch is 1000/512.

Please suggest .


many Thanks

Hi,

Try setting 512/256 for channel switching setting.

Many Thanks for your response ,

Setting 512/256 will be implemented for RNC , will have impact on all the UE Categories . I want to change some setting to make Datacard connection on HS which will reduce RTT as UE is already connected with DCH Channel only.

Please suggest .

Many Thanks

I have found one difference Max bit rate for Downlink in case of Datacard (256000 Kbps) is very high as compared to UE (8640 Kbps) and other network setting. I guess it is related to HLR QOS .

Please suggest whether re-tuning will help or not.
