Reply To: ATT flag


Hi Selva!

There are some cases in which cell become overloaded with high traffic , so at that time network set ATT=0,
So any MS/UE is switched off it will not ask resources from network to perform IMSI Detach .But as a disadvantage network try to page the MS/UE even it is not attached to n/w but compared to signalling load occur in performing detach is more if compared to paging ,so in that scenario its better to set ATT=0 and of course on expiry of mobile reachable timer MS/UE IMSI will be marked detached by the network. so overall to save the resources in case of heavy traffic in cell N/w set the ATT =0
