Abstract

A method for controlling an execution (signalling) of a non-3rd generation partnership project (3GPP) interworking function (N3IWF) is provided. The method includes splitting a signalling of a N3IWF into a control plane signalling and a user plane signalling, where the control plane signalling is handled by an N3IWF-C device and the user plane signalling is handled by an N3IWF-U device. Further, the method includes adding the E10 interface between the N3IWF-C device and the N3IWF-U device. Further, the method includes monitoring the E10 interface, whereas the E10 interface includes an E10AP. The N3IWF-C device and the N3IWF-U device enables a plurality of services between the N3IWF-C device and the N3IWF-U device. The plurality of services includes an interface management service, a bear management service, a trace management service, and a load management service.

First claim

What is claimed is:

1. A method for controlling an execution of a non-3 rd generation partnership project (3GPP) interworking function (N3IWF), the method comprising:
splitting a signalling of the N3IWF into a control plane signalling and a user plane signalling, wherein the control plane signalling is handled by a N3IWF control plane (N3IWF-C) and the user plane signalling is handled by a N3IWF user plane (N3IWF-U);
adding an E10 interface between the N3IWF-C and the N3IWF-U; and
monitoring the E10 interface, wherein the E10 interface comprises an E10 application protocol (E10AP).

2. The method of claim 1 , wherein the monitoring, by the N3IWF-C and the N3IWF-U, of the E10 interface comprises:
enabling, by the N3IWF-C and the N3IWF-U, a plurality of services between the N3IWF-C and the N3IWF-U,
wherein the plurality of services comprises at least one of an interface management service, a bear management service, a trace management service, or a load management service.

3. The method of claim 1 , wherein the E10AP runs on a stream control transmission protocol (SCTP) of a transport layer.

4. The method of claim 1 , wherein the E10AP comprises user equipment (UE) associated services and non-UE-associated services.

5. The method of claim 1 , wherein the E10 interface enables the N3IWF-U to handle Internet protocol security (IPSec) user plane traffic.

6. The method of claim 1 , wherein the N3IWF-C selects one of the N3IWF-U from a plurality of the N3IWF-U during a protocol data unit (PDU) session establishment based on a local selection mechanism.

7. The method of claim 1 , wherein the N3IWF-C is capable of moving UE context from one N3IWF-U to another N3IWF-U during failure scenarios.

8. The method of claim 2 , wherein the interface management service comprises at least one of a reset service, an error indication service, an N3IWF-U E10 setup service, an N3IWF-U E10 setup response, an N3IWF-U E10 setup failure, an N3IWF-C E10 setup service, an N3IWF-C E10 setup response, an N3IWF-C E10 setup failure, an N3IWF-U configuration update service, an N3IWF-U configuration update acknowledge, an N3IWF-U configuration update failure, an N3IWF-C configuration update service, an N3IWF-C configuration update acknowledge, an N3IWF-C configuration update failure, an N3IWF-C configuration service, an E10 release service, or an N3IWF-U status indication service.

9. The method of claim 2 , wherein the bear management service comprises at least one of a bearer context setup service, a bearer context release request for the N3IWF-C, a bearer context release request for the N3IWF-U, a bearer context modification for the N3IWF-U, a bearer context modification for the N3IWF-C, a bearer context inactivity notification service, or a data usage report service.

10. The method of claim 2 , wherein the trace management service comprises at least one of a trace start service or a deactivate trace service.

11. The method of claim 2 , wherein the load management service comprises at least one of a resource status reporting initiation service or a resource status reporting service.

12. A non-3 rd generation partnership project (3GPP) interworking function control plane (N3IWF-C) for controlling an execution of a N3IWF, the N3IWF-C comprising:
a memory;
at least one processor; and
an interface controller, operably connected to the memory and the at least one processor, configured to:
split a signalling of the N3IWF into a control plane signalling, wherein the control plane signalling is handled by the N3IWF-C,
add an E10 interface between the N3IWF-C and a N3IWF-U, and
monitor the E10 interface, wherein the E10 interface comprises an E10 application protocol (E10AP).

13. A non-3 rd generation partnership project (3GPP) interworking function user plane (N3IWF-U) for controlling an execution of a N3IWF, the N3IWF-U comprising:
a memory;
at least one processor; and
an interface controller, operably connected to the memory and the at least one processor, configured to:
split a signalling of the N3IWF into a user plane signalling, wherein the user plane signalling is handled by the N3IWF-U,
add an E10 interface between an N3IWF-C and the N3IWF-U, and
monitor the E10 interface, wherein the E10 interface comprises an E10 application protocol (E10AP).

14. The N3IWF-U of claim 13 , wherein the at least one processor is further configured to:
enable, by the N3IWF-C and the N3IWF-U, a plurality of services between the N3IWF-C and the N3IWF-U,
wherein the plurality of services comprises at least one of an interface management service, a bear management service, a trace management service, or a load management service.

15. The N3IWF-U of claim 13 , wherein the E10AP runs on a stream control transmission protocol (SCTP) of a transport layer.

16. The N3IWF-U of claim 13 , wherein the E10AP comprises user equipment (UE) associated services and non-UE-associated services.
