Claim 7:
8. A first network node, which node is a mobility management entity (MME) or an access and mobility management function (AMF), comprising:
one or more processors; and
one or more memories comprising computer program codes which, when executed by the one or more processors, cause the first network node to:
receive an initial message fora 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
determine that the UE is the category M device based on the initial message, wherein a category M of the UE is used to select a dedicated core network (DCN) for the UE as a category M device.
