Abstract

In one embodiment, a New Radio (NR) core network system comprises a set of network functions to: receive a request from a user equipment (UE) device comprising a virtual local area network data network name (VLAN DNN); determine whether the UE device is authorized to access a particular VLAN implemented on the core network and associated with the VLAN DNN; and cause a message comprising a VLAN identifier (VLAN ID) to be transmitted to the UE device based on a determination that the UE device is authorized to access the particular VLAN, wherein the VLAN ID corresponds to the particular VLAN.

First claim

What is claimed is:

1. An apparatus for a New Radio (NR) core network system, the apparatus comprising:
memory comprising instructions; and
one or more processors to execute the instructions to implement an access and mobility function (AMF) to:
receive a request from a user equipment (UE) device comprising a virtual local area network data network name (VLAN DNN);
select a session/slice management function (SMF) based on a determination that the SMF supports a particular VLAN implemented on the NR core network system and associated with the VLAN DNN;
cause the SMF to determine whether the UE device is authorized to access the particular VLAN; and
transmit a message comprising a VLAN identifier (VLAN ID) to the UE device based on the determination by the SMF that the UE device is authorized to access the particular VLAN, wherein the VLAN ID corresponds to the particular VLAN.

2. The apparatus of claim 1 , wherein the VLAN DNN is obtained from the UE device via a packet data unit (PDU) session establishment request, and the VLAN ID is to be transmitted to the UE device via a PDU session establishment accept message.

3. The apparatus of claim 1 , wherein the one or more processors are to implement the AMF to send a Namf_PDUSession_CreateSMContext Request to the SMF comprising the VLAN DNN.

4. The apparatus of claim 1 , wherein the one or more processors are to implement the AMF to receive a Namf_Communication_NIN2MessageTransfer message from the SMF, wherein the Namf_Communication_NIN2MessageTransfer message comprises the VLAN ID.

5. The apparatus of claim 1 , wherein the one or more processors are to implement the AMF to provide the VLAN DNN to the UE device in response to receiving a request from the UE device comprising a VLAN DNN query as a protocol configuration option (PCO) or extended PCO (ePCO).

6. The apparatus of claim 1 , wherein the one or more processors are to implement the AMF to provide an address of a VLAN Function to the UE device based on a request from the UE device comprising a protocol configuration option (PCO) or extended PCO (ePCO) indicating a request for the address of the VLAN function.

7. The apparatus of claim 6 , wherein the PCO or ePCO comprises a VLAN request flag to indicate the request for the address of the VLAN function.

8. A method to be performed by an access and mobility management function (AMF) of a New Radio (NR) core network system, the method comprising:
receiving a request from a user equipment (UE) device comprising a virtual local area network data network name (VLAN DNN);
selecting a session/slice management function (SMF) based on a determination that the SMF supports a particular VLAN implemented on the NR core network system and associated with the VLAN DNN;
causing the SMF to determine whether the UE device is authorized to access the particular VLAN; and
transmitting a message comprising a VLAN identifier (VLAN ID) to the UE device based on the determination by the SMF that the UE device is authorized to access the particular VLAN, wherein the VLAN ID corresponds to the particular VLAN.

9. The method of claim 8 , further comprising providing the VLAN DNN to the UE device in response to receiving a request from the UE device comprising a VLAN DNN query as a protocol configuration option (PCO) or extended PCO (ePCO).

10. The method of claim 8 , wherein the message is transmitted in response to receiving a request from the UE device comprising a VLAN DNN query as a protocol configuration option (PCO) or extended PCO (ePCO).

11. The method of claim 8 , further comprising providing an address of a VLAN Function to the UE device based on a request from the UE device comprising a protocol configuration option (PCO) or extended PCO (ePCO) indicating a request for the address of the VLAN function.

12. A computer-readable non-transitory storage medium comprising computer-executable instructions operable to, when executed by at least one computer processor, enable the at least one computer processor to perform the method of claim 8 .

13. A computer-readable non-transitory storage medium comprising computer-executable instructions operable to, when executed by at least one computer processor, enable the at least one computer processor to perform the method of claim 9 .

14. A computer-readable non-transitory storage medium comprising computer-executable instructions operable to, when executed by at least one computer processor, enable the at least one computer processor to perform the method of claim 10 .

15. A computer-readable non-transitory storage medium comprising computer-executable instructions operable to, when executed by at least one computer processor, enable the at least one computer processor to perform the method of claim 13 .
