    Re: High RTWP level in Huawei UMTS network

    How to check RNC parameter for RRC_CONN_REL_CMP? Thanks
  2. Question Re: how to decrease RRC and RAB fail due to NoReply

    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.
  3. Re: Difference Ec/No between Idle, and Voice CS12.2K

    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...

    Re: Cell Breathing..

    I have put a comment which makes me think twice so I edited.
  5. Question Re: How many neighbor cell can be configured of each cell

    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...
  6. Re: Recommended values of MaxPCPICHPower & MinPCPICHPower (Huawei)

    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...

    Re: IRAT HO IMPROVEMENT PARAMETER

    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.

    Question Re: RAB Ext without RRC Est

    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.
  10. Question Re: How to find the relationship between traffic and RTWP

    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...

    Question Re: 3G IRAT down

    Your 2G to 3G handover is based on what?
    Load? Service? Can you post the parameters you changed/enabled?

    Re: IRAT HO IMPROVEMENT PARAMETER

    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.

    Re: IRAT HO IMPROVEMENT PARAMETER

    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...

    Question Re: 3G IRAT down

    By your statement 3G IRAT decrease meaning less ISHO attempts or IRAT SR degraded?
  15. Re: Inter System HO from 3G to 2G ; NSN versus Huawei

    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...

    Re: 3G drop call with CC disconnect message

    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.

    Re: Cell Breathing..

    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,...

    Re: Pilot pollution on Actix

    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.
  22. Re: What are the other parameters to change when increasing the CPICH power

    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...
