procedure
Feature Changes
Behavior Change for Emergency TAU Attach Without Active Flag Set
Previous Behavior: During a TAU attach, when Active Flag (AF) is not set in TAU request, the UE is moved to idle
state.

New Behavior: During inbound TAU of emergency calls, the UE will be moved to connected state even when AF is
not set, so that the NI-LR LCS procedure can be successful. This is done only if it is an emergency call and location
service is configured. If it is not an emergency call, then the previous behavior will be valid and the UE will move to
idle state when AF is not set.
