1. A method performed by a first network node, wherein the first network node is a mobility management entity (MME) or an access and mobility management function (AMF), the method comprising:
receiving an initial message for a user equipment (UE) from a second network node, wherein the second network node is a radio access network (RAN) node and wherein the second network node transmits the initial message to the first network node to indicate that the UE is a category M device, based on a radio resource control (RRC) message from the UE indicating that the UE is a category M device, wherein the category M of the UE is indicated by a long term evolution (LTE)-M indication for evolved-universal terrestrial radio access (E-UTRA); and
determining that the UE is a category M device based on the initial message,
wherein a category M of the UE is used for selecting a dedicated core network (DCN) for the UE as a category M device.
