@ Basharat : Hi, Its important to realize the traffic in the LAC. Check if its correctly dimensioned. Cover the coverage holes too. Yes there is a mechanism of calculating MFRMS, can share it offline, its a doc. Anyway, pls understand that for high traffic environment i.e. utilization of LAC is >75%, use higher value of MFRMS like 5 or 6(depending upon traffic). Tell me what is the Implicit detach timer value for the network?
