Cellular internet of things (CIoT) optimizations for narrowband (NB) and non-NB IoT networks

An apparatus of a user equipment (UE) operable to support Cellular Internet of Things (CIoT), the apparatus comprising memory;

• and one or more processors configured to:
• generate, at the UE, a radio resource control (RRC) connection setup complete message that includes one or more indicators that one or more CIoT Evolved Packet System (EPS) optimizations are supported at the UE to enable the UE to request a use of the CIoT EPS optimizations from an evolved NodeB (eNodeB);
• and
• signal, at the UE, the RRC connection setup complete message that includes the one or more indicators for transmission to the eNodeB, wherein the one or more indicators in the RRC connection setup complete message include an attach without packet data network (PDN) connectivity indicator to indicate that the UE performs attach without PDN connectivity.

At least one non-transitory machine readable storage medium having instructions embodied thereon for supporting Cellular Internet of Things (CIoT) at an eNodeB, the instructions when executed by one or more processors at the eNodeB perform the following:

• generating, at the eNodeB, a system information block (SIB) that includes one or more indicators that one or more CIoT Evolved Packet System (EPS) optimizations are supported at the eNodeB, wherein the eNodeB is included in a non-narrowband (non-NB) CIoT radio access network (RAN), wherein the one or more indicators in the SIB include an attach without packet data network (PDN) connectivity indicator that denotes support at the eNodeB for attach without PDN connectivity, or wherein the one or more indicators in the RRC connection setup complete message include an attach without PDN connectivity indicator that the UE performs attach without PDN connectivity;
• signaling, at the eNodeB, the SIB that includes the one or more indicators for transmission to a user equipment (UE) that is configured for non-NB CIoT;
• and
• decoding, at the eNodeB, a radio resource control (RRC) connection setup complete message received from the UE, wherein the RRC connection setup complete message includes one or more indicators that one or more CIoT EPS optimizations are supported at the UE.
