POOR CSSR 2G E*******

[Aminoo]

Hi Team

Please share your knowledge about the Poor CSSR CS in GSM E*******.

I have a cell that have dual band (900, 1800 ) 4+4+4 (900) 3+3+2(1800) and 12 SDCCH, and i have very high drop due to location update and low SS.

How can i emproove the CSSR and SDCCH drop.

Thanks for your help

Hi,

If low SS, please evaluate TA, and try to downtilt or coverage asessment so drop due to low SS will be reduced.

Is your cell is MBC with OL/UL configuration. if so check the sdcch configuration is only on UL or else check the configurations for OL immediate assignment parameters
