Abstract

Systems, apparatuses, methods, and computer-readable media are provided for a user equipment (UE) of a wireless communication system. The UE includes a processor circuitry, and radio front end circuitry coupled to the processor circuitry. The processor circuitry is configured to determine and indicate, to a core network via a radio access network (RAN), one or more cellular internet of things (CIoT) features that are required by the UE and CIoT network behavior expected from the core network to support the one or more CIoT features that are required by the UE. The processor circuitry is configured to select either an enhanced packet core (EPC) or a 5G core (5GC) to establish a wireless connection with the core network, based on a first set of CIoT features supported by the EPC and a second set of CIoT features supported by the 5GC received from the core network.

Claims20

Dependent claims

A user equipment (UE) comprising:

processor circuitry configured to:
determine, at the UE, one or more cellular internet of things (CIoT) features that are required by the UE;
indicate, from the UE to a core network via a radio access network (RAN), 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);
indicate, from the UE to the core network via the RAN, CIoT network behavior expected from the core network to support the one or more CIoT features that are required by the UE;
receive, 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;
and
select the EPC or the 5GC to establish a wireless connection with the core network, the selection based on the first set of CIoT features supported by the EPC and the second set of CIoT features supported by the 5GC;
and
radio front end circuitry, coupled to the processor circuitry, configured to:
exchange, between the UE and the core network via the RAN, one or more mobility access and management procedure messages based on the selected EPC or 5GC.

7 more elements

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), 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.

4 more elements

A non-transitory computer-readable media (CRM) comprising computer instructions, where upon execution of the computer instructions by one or more processors of a user equipment (UE), causes the one or more processors to:

determine, at the UE, one or more cellular internet of things (CIoT) features that are required by the UE;
indicate, from the UE to a core network via a radio access network (RAN), 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);
indicate, from the UE to the core network via the RAN, CIoT network behavior expected from the core network to support the one or more CIoT features that are required by the UE;
receive, 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;
select, 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
establish a connection with the core network based on the selected PEC or 5GC.
