Abstract: Embodiments disclosed herein relate to methods for handling a resource in a wireless network by a UE 100. The method includes receiving a reject cause message from a network entity. The UE does not support a redirected radio access technology (RAT) indicated in the reject cause message. Further, the method includes considering the reject cause message to represent an abnormal case and performing at least one action based on the abnormal case. The method can be used for enabling enhanced NAS procedure in CIoT devices. The method can also be used to indicate the change in support of CP/UP preference when both CP and UP CIoT optimization are supported, so as to reduce the signalling overhead in the wireless network, improve the UE behavior and NAS procedural efficiencies.
