Abstract

Methods, apparatus, and systems are described for improved edge network access for a UE. According to some aspects, a UE may receive a first Data Network Name (DNN) from an application and determine, based on a Data Network Name (DNN) Replacement Rule, the first DNN is associated with a second Data Network Name (DNN), where the first DNN and the second DNN are different. The UE may determine, based on the DNN Replacement Rule, to associate traffic from the application with a Protocol Data Unit (PDU) Session, where the PDU Session may be used to send data from the application to a network and the PDU Session is associated with the second DNN.

First claim

What is claimed is:

1. A wireless transmit/receive unit (WTRU), comprising a transceiver and one or more processors, configured to:
receive a user equipment route selection policy (URSP) rule comprising a traffic descriptor and a route selection descriptor (RSD), wherein the traffic descriptor includes a first data network name (DNN) and the RSD includes a second DNN;
determine information indicating a DNN provided by an application;
determine that the DNN provided by the application matches the first DNN;
based on determining that the DNN provided by the application matches the first DNN, determine, based on the RSD, a protocol data unit (PDU) session associated with the second DNN; and
route, using the PDU session, traffic provided by the application.

2. The WTRU of claim 1 , wherein being configured to determine the PDU session comprises being configured to send a PDU session establishment request comprising the second DNN.

3. The WTRU of claim 2 , wherein the PDU session establishment request includes an indication that the second DNN is a replacement DNN.

4. The WTRU of claim 3 , wherein the WTRU is configured to communicate with a further WTRU using a visible light link.

5. The WTRU of claim 1 , wherein the PDU session is an existing PDU session.

6. The WTRU of claim 1 , wherein the WTRU is configured to receive the URSP rule in a Non-Access Stratum (NAS) message.

7. The WTRU of claim 1 , wherein the WTRU is configured to send an indication that the WTRU is configured to receive the USRP rule and wherein the WTRU is configured to receive the USRP rule in response to the indication.

8. The WTRU of claim 7 , wherein the WTRU is configured to send a registration request including the indication.

9. The WTRU of claim 1 , wherein the WTRU is configured to receive the USRP rule in a user equipment configuration update message.

10. The WTRU of claim 1 , wherein being configured to determine the DNN provided by the application matches the first DNN comprises being configured to determine the DNN provided by the application is equal to the first DNN.

11. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
receiving a user equipment route selection policy (URSP) rule comprising a traffic descriptor and a route selection descriptor (RSD), wherein the traffic descriptor includes a first data network name (DNN) and the RSD includes a second DNN;
determining information indicating a DNN provided by an application;
determining that the DNN provided by the application matches the first DNN;
based on determining that the DNN provided by the application matches the first DNN, determine, based on the RSD, a protocol data unit (PDU) session associated with the second DNN; and
routing, using the PDU session, traffic provided by the application.

12. The method of claim 11 , wherein determining the PDU session comprises sending a PDU session establishment request comprising the second DNN.

13. The method of claim 12 , wherein the PDU session establishment request includes an indication that the second DNN is a replacement DNN.

14. The method of claim 13 , wherein the WTRU is configured to communicate with a further WTRU using a visible light link.

15. The method of claim 1 , wherein the PDU session is an existing PDU session.

16. The method of claim 11 , wherein the URSP rule is received in a Non-Access Stratum (NAS) message.

17. The method of claim 11 , wherein the WTRU is configured to send an indication that the WTRU is configured to receive the URSP rule and the URSP rule is received in response to the indication.

18. The method of claim 17 , wherein the indication is sent in a registration request.

19. The method of claim 11 , wherein the URSP rule is received in a user equipment configuration update message.

20. The method of claim 11 , wherein determining that the DNN provided by the application matches the first DNN comprises determining the DNN provided by the application is equal to the first DNN.
