8. A method, comprising:
determining, at a user equipment (UE), one or more cellular internet of things (CIoT) features that are required by the UE;
indicating, from the UE to a core network via a radio access network (RAN), a capability of the UE to support the one or more CIoT features that are required by the UE, wherein the core network comprises an enhanced packet core (EPC) and a 5G core (5GC);
indicating, from the UE to the core network via the RAN, CIoT network behavior expected from the core network to support the determined one or more CIoT features that are required by the UE;
receiving, at the UE, from the core network via the RAN, a first set of CIoT features supported by the EPC and a second set of CIoT features supported by the 5GC;
selecting, based on the first set of CIoT features supported by the EPC and the second set of CIoT features supported by the 5GC, the EPC or the 5GC to establish a wireless connection with the core network; and
establishing a connection with the core network based on the selected EPC or 5GC.
