How calculate the TCH accessibility.
How to calculate the TCH accessibility.pls help me any body.
In my point of view TCH accessibility is directly proportional to TCH blocking. As you improve the TCH blocking your TCH accessibility will improve
Is there any equation to calculate the TCH blocking for ZTE
Formula for TCH blocking is :
number of TCH seizure failure * 100 / number of TCH seizure attempt
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.
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, Please give me tips for improving sd drop. ( Here we are using NOKIA system ) Mainly for overshooting cells what whould be the parameters that I need to look for…
please explain KPI in details to me?
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.
Could u explain me wat exactly is definition of TCh Blocking and SD Blocking. Wats teh difference btw Blocking, Congestion and drop.
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..
CRH (Cell Reselect Hysteresis),You need to search HYS in NED.
Default value is 4,Can be increases as per requirement.
