How to check RNC parameter for RRC_CONN_REL_CMP? Thanks
Check worst cells if FACH utilization high and add another SCPCCH. This could be due to FACH congestion since RRC connection request uses FACH channel.
For you to compare Ec/No in 2 scenario, everything should be equal so its apple to apple. I assume this is in different time since you use same MS for idle and voice.
1. Same time?
2. Same cell...
I have put a comment which makes me think twice so I edited.
Check the AUTODEF measurements or cell to cell handover stats(Huawei) to define "enough" neighbours. Use 1 week data just to be sure then aggregate. Just be careful with deleting neighbours, some...
Just to add in detail, when capacity of a cell is higher than a relative threshold(CellOverrunThd, usually 90%), the cell decreases the CPICH power by a value(PCPICHPowerPace, default 0.2 dB) and the...
The question is even if the network enabled R8 fast dormancy feature, only R8 mobile will get the advantage which is not much..
We set it to 20 MR actually. Each MR can take 0.5 sec(another parameter i forgot already). So a total max CM time of 10 secs.
Is this cell a second carrier?
It might be that the RRC is setup in F1 and then directed to F2 to perform the RAB Estab.
RTWP is total UL load of a cell. This includes but not limited to,
Own cell interference Traffic(AMR,UDI,PSR99,HSPA,etc)
Other cell interference - UE connected to multiple cells(too much...
Your 2G to 3G handover is based on what?
Load? Service? Can you post the parameters you changed/enabled?
Monitor RAB DR, once this gets bad it means the setting is too high. Might want to test this for PS call first.
Check also interference, since you make Compressed Mode longer with GsmMaxMeasPeriod.
There will be much better results if you include "AdjgRxlevminHO" together with "GsmMaxMeasPeriod".
Set AdjgRxlevminHO step by step making it harder to perform ISHO.
For example:
Step 1: -95 dBm...
By your statement 3G IRAT decrease meaning less ISHO attempts or IRAT SR degraded?
Hi Kyokuman,
Did CPICH power increase? Both NSN and Huawei CPICH reference point are after the RF module. -
If CPICH increase/decrease then you increase/decrease the coverage, BUT then your...
Did you see MR with event 1B in SC2? or is it SC1 in the MR?
If "CC Disconnect" sent after "CC Progress" then its more likely system issue or the test number.
If "CC Disconnect" sent after "Call Proceeding" then its more likely RNC issue.
"Too many servers" and "Pilot pollution" can be the same at some points but not all the time.
"Too many servers" is always true in "Pilot pollution" but "pilot pollution" is not always true in "Too...
This is how I understand it. Cell breathing
doesn't affect RSCP,
affects Noise but not Energy/chip(Ec) so thats why we have poor Ec/No during high load.
Suppose UE is situated in RSCP -80dBm,...
Try this query, > 4 serving cell within within 5dB window. You can edit this in actix if you want wider window.
Have you checked the PCH throughput and Paging SR(Need help from Core) in your network?
In 3G, it should not exceed 4kbps per LAC if im not mistaken.
Please be aware that increasing CPICH power by X dBm will also increase common channel power PtxPrimaryCCPCH, PtxPICH, PtxAICH, etc. by x dBm. Because these common channels are relative to CPICH...
its a repost of below I double clicked.. :)
Hi Paboya,
I believe the sample database format is already included in the attachments.. :) and also the user-guide "how to"..
Thanks..
Hi Umar,
For your first question, you can try dv_Com tool in this link http://www.finetopix.com/nokiasiemens/16439-dvcom_3g-optimisation-tool.html This is the best tool in MapInfo in my opinion,...
