ali moh’… it means that all the radio channels TCH / SDCCH are fully utilized and that a certain amount of calls is rejected because they have no resource available in the cell.
for instance : TCH congestion rate of CELL A = 3.5% means that 3.5% of the subscribers that tried to perform a call in the cell A were rejected (= blocked call OR the call is handover to a neighbor cell).
