5. A method performed by a user equipment (UE) comprising:
generating a radio resource control (RRC) message 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
transmitting the RRC message to a second network node, which second network node is a radio access network (RAN) node, to facilitate an initial message to be transmitted from the second network node to a first network node, which first network node is a mobility management entity (MME) or an access and mobility management function (AMF), wherein the initial message indicates that the UE is a category M device and for the first network node to use a category M of the UE to select a dedicated core network (DCN) for the UE as a category M device.
