No, that’s not your problem.
When you’re doing the drive test, stop at the point where you should reselect Cell 1, but you’re actually reselected to Cell 2.
Give me the following value, for EACH cell :
and the following cell parameters : RXLEV_ACCESS_MIN
Then we can tell you why you don’t reselect cell 1 🙂

I hope you make us understand thanks in advance.18th February 2008 at 06:09 #50687PixGuest
And what about the RXLEV ?18th February 2008 at 06:41 #50688MazinGuest
you mean the RXLEV i get from Drivetest you mean?18th February 2008 at 14:39 #50689pixGuest
yes, the average rxlev you get from cell 1 and cell 2, static car, at a point where you expect to reselect cell 1.

as the problem now disappeared i remeber one time it was cell1=-61 and for cell2=-7119th February 2008 at 05:55 #50691PixGuest
You said “every time the c2 value of Cell2 was higher than the c2 value of the cell1 the reason was as i think i had 4 trx in cell2 and 6 trx in cell1 maybe that was the problem.”
And then you say : RxLev(cell 1) = -61dBm and RxLev(cell 2) = -71dBm
This is impossible with your parameter settings. In your situation, C2(cell 2) should be lower than C2(cell 1). It seems you need to double check your measures, they don’t seem accurate.
The output power of the antenna is not taken into account in the C2 computation : whether there is 4 or 6 TRX, it wouldn’t change anything, except a lower rxlev in the mobile.
