Abstract
A user equipment (UE) implementing a message recovery method is disclosed, supporting messages of both the circuit switched (CS) domain and the packet switched (PS) domain. The UE roams in a wireless telecommunications system and performs a call setup procedure. When the UE receives an NAS message comprising a domain identifier and a protocol discriminator, the UE determines whether the domain identifier and the protocol discriminator are of the same domain. If the domain identifier and the protocol discriminator are of the same domain, the UE proceeds with processes corresponding to the NAS message. If the domain identifier and the protocol discriminator are of different domains, the NAS message is determined to be an error message, and the UE modifies the domain identifier of the NAS message to generate a recovered NAS message, and determines whether the recovered NAS message is compatible to the call setup procedure.
