I am checking Handover relation performance ,, the pM tells me that the handovers reasons are:-
1-Number of handover attempts from selected cell to the adjacent cell due to better UL quality.
2- due to better DL quality.
3-due to better UL strength.
4-due to better DL strength.
5-due to PBGT.
6-due to other factors.
but it is accoding to gsm ralation , for example
CO_Band_Cell ;DCS1800-P-GSM900(Same ID; Same cell ID ;Differenet band) 99.99 % for handover reasons is UL/DL quality and strength , whith high ping pong .
93.6% for handover reasons is Other factor and 6% UL/DL quality and strength , with low % of ping pong.
A)-is there clear handover stragtegy
B)-what is the prefered handover reasons from the above reasons . C)-is there limits for distance between nighboors we habe some casess are reached more than 20 km .
the handover share % between nighboors is it controlled ,, is raeched to 70% between main cell 900 and co band cell 1800 .??
thanks in advanced .
