    Dear Expert;

    Is there any relation between the immediate assignment failure for TCH and the GPRS.

    I’m facing an issue in CSSR,Blocking due to high imm_assig_failure affecting a cluster of cells near each other .I have changed the hardware ,do a lot of BCCH/BSIC changes with out any effect.one of the cells may be reach 30% immediate assignment failure.

    Today ,I tried to Disable the GPRS on the cell and I got a change from 13% failure into 2% failure.still I didn’t check the other cells yet.

    Does anyone has an explaination regarding this?
