dear
can any body help me that I checked in TEMS ( neighbor and serving cell) the same cell appear in different RX level let say
cell A RX level -56dBm amd in the same next one cell A RX level -65 dBm
Might be two cells with same BCCH and BSIC serving in the area. If this is the case, you must be having very bad HSR and Random Access Success Rate there.
One of them is serving and other the neighbor right? Please check if you have included the own BCCH of serving cell in the Active BA list. I am working on Ericsson and they have introduced this feature “Own BCCH” in R12 to improve the multiband cell performance.
Well as per my understanding in some operators a parameter like Pbgt_Mode is provided which is especially useful for dual band cells. It allows an MS on the DCS inner zone of the cell to compensate for the difference in the prorogation losses of the two frequencies GSM-BCCH and DCS Inner zone.
dear bilal
thanks for your reply
but for more information I have onle singleband(900) and also the BCCH is not included in the BA list and this make me surprise for appearing same BCCH for the same cell with different RX level
Since its a parameter like pbgt_mode=0 add the serving cell to the BA list. now the MS only reports 5 neighhbours as the 6th is the serving cell. in your case this parameter can be wrongly set as it would still work in the same manner even if no inner zone.
