1. A method performed by a first access management entity of a network, comprising:
determining whether a user equipment (UE) is using LTE-M radio access technology (RAT);
obtaining access restriction or RAT restriction data associated with the UE, wherein the access restriction or RAT restriction data includes first information indicating whether the UE is allowed to use the LTE-M RAT type and second information indicating whether the UE is allowed to use a WB-E-UTRAN RAT type other than the LTE-M RAT type; and
determining whether the UE is allowed to attach or register to the network based on the obtained access restriction or RAT restriction data associated with the UE;
wherein the access restriction or RAT restriction data indicating whether the UE is allowed to use the LTE-M RAT type is a second bit and the access restriction or RAT restriction data indicating whether the UE is allowed to use a WB-E-UTRAN RAT type other than the LTE-M RAT is a third bit, and wherein the second bit and the third bit are only used when a first bit for indicating whether the WB-E-UTRAN RAT type is not allowed is not set.
