Abstract: This disclosure describes example embodiments and techniques to resolve UE behavior for several SAR use cases. The substate selection for a UE which has a valid SAR list and is currently camped on a cell which is in the registered PLMN or a PLMN from the list of equivalent PLMNs and whose TAI is not in the list of “allowed tracking areas” or is camped on a cell whose TAI is in the list of “non-allowed tracking areas,” has gaps in functionality and certain use cases. There are conflicting requirements as to what is the substate to be chosen by the UE. Additionally, there are certain behaviors missing for a UE in substate 5GMM-REGISTERED.NON-ALLOWED-SERVICE.
