Hello!
As I guess, handover was attepted from BTS 92 to other cell, but it was failed. 92 is source BTS.
01 = the BSC has detected an error in the adjacent cell definitions.
07 = BCC of Target BTS
04 = NCC of Target BTS
820 = BCCH of target cell
So, try to do as following:
ZEAO:BTS=92.
You will get list of cells, which are adjacent cells for Cell92. In the output you find problem target cell description including BCCH=820, NCC=04 and BCC=07.
Regards.
