Hi All.

Is there any 3GPP or vendor based document of how and when the UE shall retransmit a new TAU request?

For example MME retransmit the tracking update accept message based on a 3GPP timer t3450 or if it is received a 2nd TAU update request from the UE?

You can refer 3gpp 24.301 for UE side TAU, there are all scenarios and timers available.
