1. A User Equipment (UE) comprising:
a memory; and
a processor coupled with the memory,
wherein the processor is configured to:
send an IKE_AUTHREQ message to a Non-3rd Generation Partnership Project (3GPP) InterWorking Function (N3IWF) node, wherein the IKE_AUTH_REQ message includes one or more Single Network Slicing Selection Assistance Information (S-NSSAIs);
receive an IKE_AUTH_RSP message from the N3IWF node based on the S-NSSAIs in the IKEAUTHREQ message only including one or more S-NSSAIs indicated in an OVERLOAD START message received by the N3IWF node, wherein the IKE_AUTH_RSP message includes an information element to notify a congestion in a network, and wherein the IKE_AUTH_RSP message further includes a value of a backoff timer; and
not restart a procedure related to Non-Access Stratum (NAS) by the UE until the backoff timer expires.
