    Hi Suresh
    half rate to full rate parameter-Ratio of TCHH(%)
    full rate to half rate parameter-TCH Traffic Busy Threshold(%)
    intra cell handover parameter-Intracell HO allowed
    queuing-Allow EMLPP
    cls parameter-Load HO Allowed
    ondemand pdch parameter-Maximum Ratio Threshold of PDCHs in a Cell(%)
    spdch-Huawei doesn’t have SPDCH concept.
    dynamic allocation-PDCH reforming
    uplink 4 timeslot-Allocate Two Timeslots Switch for MS over Uplink.Till C12 version huwai supprts only 2 TSL in UL.

    Hi bijoy,

    thanks buddy great thanks a lot.

    still want to know abt some parameter

    here pdch reforming is for PS to CS.

    but which parameter is for CS to PS. IF THERE IS PLZ TELL. because if i am defining dynamic pdch and there is more cs traffic then it will preempt my edge pdch.
    So plz tell this also if possible plz tell which are there counters.

    Hi Suresh
    Check out these parameters
    1.Level of Preempting Dynamic Channel
    2.Reservation Threshold of Dynamic Channel Conversion
    For counters,check R93* counters

    Thanks Pix.Hope you will arrange some water:-)(kidding dear)

    Sure ,there is.
    1.IntraCell AMR TCHH-TCHF Qual Ho Allowed
    2.IntraCell AMR TCHH-TCHF Ho Qual. Threshold
    3.IntraCell AMR TCHF-TCHH Ho Qual. Threshold
    4.IntraCell AMR TCHF-TCHH Qual Ho Allowed

    Hi bijoy,

    thanks buddy here i am facing the problem of poor ho sucess at bsc boundries within same msc everywhere in my network so by enabling handover power boost will help to improve ho sucess?

    Hi Suresh
    HPB will definitely supress the poor radio environment.Also try increasing the Timers T3107 & T3121.

    Like RPP in Er\\,in huawei we have GDPUP(PCU).
    Max PDCH(static+dynamic) per PCU =1024.
    Max cells per PCU =2048
    Max PDCH per BSC=8192.
    Max PCU Num=32.

    Hi Suresh
    HPB will not impact TCH Drop.
    Rgarding PCU,this is what I know for BSC6000.

    Regarding Nokia,max no. of logical PCU for BSCi was 8+1,higher versions have much more,say the latest flexi BSC have 60+10 logical PCU.

    Hi Suresh
    With HPB, the BTS transmit power is adjusted to the maximum before the BSC sends a handover command to the MS. In addition, the BTS transmit power is not adjusted during the handover to ensure the success of the handover.

    When the receive level of an MS drops rapidly, a handover occurs. In this case, the BSC cannot adjust the transmit power of the MS and BTS in time. The MS may fail to receive the handover command, thus leading to the call drop.
