If UE sends attach request in Uplink and gets no answer from RAN to RRC connection request in good RF, how often it should repeat the Attach request / RRC connection request?
I believe every 5 seconds, Is there a timer for this?
Because I have seen cases where for 11 seconds UE is not sending again Attach request / RRC connection request in good RF.
NAS timers come into picture only after RRC declares failure for the connection establishment.
Probably in your case RRC reported failure after 1sec and NAS retrys attach recovery after T3411 which is 10 secs (NR also has T3511 with the same default value of 10secs).
