    In my point of view TCH accessibility is directly proportional to TCH blocking. As you improve the TCH blocking your TCH accessibility will improve

    Hi,
    Formula for TCH blocking is :
    number of TCH seizure failure * 100 / number of TCH seizure attempt

    Hi all,
    It is not 100% true.
    There could be losses not only due to blocking (SDCCH, TCH, ABIS, A …) but also due to HW failure. For example: in case of cross connected Antennas between sectors, or one of TRX could be damaged.

    Hi Akramots,

    that’s true, failure can be due to various reasons, but all these will come in failure part
    the formula i have given is a general formula

    Hi Srinivasa,

    Is the Cells with high SD Drop a border Cell? Check out ur CRH value. Try to increase ur CRH value to 8 if not. This may reduce ur LU.

    But Bijoy,

    Could u explain me wat exactly is definition of TCh Blocking and SD Blocking. Wats teh difference btw Blocking, Congestion and drop.

    Hi Prabeen,
    Thanks for the suggestion. A small elaboration on CRH will be helpful. We use NOKIA system here and there is no results for CRF in NED..

    Please suggest.
