This is an abnormal test case and is used for validating whether the UE is capable of reattaching if it goes through a detach collision.

The pre-requisites of this test is that the UE’s EPS Mobility Management is in the de-registered initiated state.

In this test case, the UE receives the DETACH REQUEST message from the network with cause re-attach required. Then the UE aborts the UE initiated detach procedure and completes the network-initiated detach procedure. Then the UE will complete the UE initiated the attach procedure.

The scenario executed in this test case is Reattach After Detach collision.
