Abstract: Embodiments of the present disclosure provide method and apparatus for access or RAT restriction. A method at a first access management entity of a network comprises determining that a user equipment (UE) is using LTE-M radio access technology (RAT). The method further comprises obtaining access restriction or RAT restriction data associated with the UE, wherein the access restriction or RAT restriction data indicates that LTE-M RAT type is restricted. The method further comprises determining whether the UE using LTE-M is allowed to attach or register to the network based on the obtained access restriction or RAT restriction data associated with the UE.
