Abstract

A protocol data unit (PDU) type setting method, a user equipment (UE) policy setting method, and a related entity, where the PDU type setting method includes: setting, by UE, a requested PDU type of a PDU session in a process of establishing the PDU session, where the requested PDU type of the PDU session is set by the UE based on a first condition, the first condition includes an Internet Protocol (IP) version corresponding to an application, and the application is associated with the PDU session. In the embodiments of the present disclosure, the requested PDU type of the PDU session can be consistent with a PDU type requested by the application, such that the application can normally perform communication.

First claim

The invention claimed is:

1. A protocol data unit (PDU) type setting method implemented by a user equipment (UE), wherein the PDU type setting method comprises:
obtaining a UE route selection policy (URSP) for the UE from a policy control function entity, wherein the URSP comprises a first application identifier which identifies a first application, a first Internet Protocol (IP) version corresponding to the first application, a second application identifier which identifies a second application, and a second IP version corresponding to the second application; and
setting a requested PDU type of a PDU session in a process of establishing the PDU session, wherein the requested PDU type of the PDU session is set for an application associated with the PDU session by the UE based on a first condition, wherein the first condition comprises one of the first IP version or the second IP version corresponding to the application associated with the PDU session, wherein the application associated with the PDU session is identified by one of the first application identifier or the second application identifier, and wherein setting the requested PDU type comprises setting, by the UE, in the process of establishing the PDU session, the requested PDU type of the PDU session to the one of the first IP version or the second IP version corresponding to the one of the first application identifier or the second application identifier associated with the PDU session.

2. The PDU type setting method of claim 1 , wherein the one of the first IP version or the second IP version corresponding to the application associated with the PDU session is requested by the application or an IP version recommended by the application.

3. The PDU type setting method of claim 2 , wherein the IP version recommended by the application is determined based on an IP version supported by a data network name and the first IP version or the second IP version requested by the application.

4. The PDU type setting method of claim 1 , wherein the first condition further comprises at least one of an IP stack capability of the UE or an IP version supported by a data network name.

5. The PDU type setting method of claim 4 , wherein when the first condition comprises the one of the first IP version or the second IP version corresponding to the application associated with the PDU session and the IP stack capability of the UE, setting the requested PDU type of the PDU session in the process of establishing the PDU session comprises setting, by the UE in the process of establishing the PDU session, the requested PDU type of the PDU session to an intersection of the one of the first IP version or the second IP version corresponding to the application associated with the PDU session and the IP stack capability of the UE.

6. The PDU type setting method of claim 4 , wherein when the one of the first IP version or the second IP version corresponding to the application associated with the PDU session is an IP version requested by the application, and the first condition comprises the IP version requested by the application and the IP version supported by the data network name, setting the requested PDU type of the PDU session in the process of establishing the PDU session comprises setting, by the UE in the process of establishing the PDU session, the requested PDU type of the PDU session to an intersection of the IP version requested by the application and the IP version supported by the data network name.

7. The PDU type setting method of claim 1 , wherein the first application identifier and the second application identifier comprise an application name.

8. User equipment (UE), comprising:
a memory configured to store instructions; and
a processor coupled to the memory and configured to execute the instructions to:
obtain a UE route selection policy (URSP) for the UE from a policy control function entity, wherein the URSP comprises a first application identifier which identifies a first application, a first Internet Protocol (IP) version corresponding to the first application, a second application identifier which identifies a second application, and a second IP version corresponding to the second application; and
set a requested PDU type of a PDU session in a process of establishing the PDU session, wherein the requested PDU type of the PDU session is set for an application associated with the PDU session by the UE based on a first condition, wherein the first condition comprises one of the first IP version or the second IP version corresponding to the application associated with the PDU session, wherein the application associated with the PDU session is identified by one of the first application identifier or the second application identifier, and wherein setting the requested PDU type of the PDU session comprises setting, by the UE, in the process of establishing the PDU session, the requested PDU type of the PDU session to the one of the first IP version or the second IP version corresponding to the one of the first application identifier or the second application identifier associated with the PDU session.

9. The UE of claim 8 , wherein the one of the first IP version or the second IP version corresponding to the application associated with the PDU session is requested by the application or an IP version recommended by the application.

10. The UE of claim 9 , wherein the IP version recommended by the application is determined based on an IP version supported by a data network name and the first IP version or the second IP version requested by the application.

11. The UE of claim 8 , wherein the first condition further comprises at least one of an IP stack capability of the UE or an IP version supported by a data network name.

12. The UE of claim 11 , wherein when the first condition comprises the one of the first IP version or the second IP version corresponding to the application associated with the PDU session and the IP stack capability of the UE, the processor is further configured to execute the instructions to set the requested PDU type of the PDU session in the process of establishing the PDU session by setting, by the UE in the process of establishing the PDU session, the requested PDU type of the PDU session to an intersection of the one of the first IP version or the second IP version corresponding to the application associated with the PDU session and the IP stack capability of the UE.

13. The UE of claim 11 , wherein when the one of the first IP version or the second IP version corresponding to the application associated with the PDU session is an IP version requested by the first application identifier or the second application identifier, and the first condition comprises the IP version requested by the application and the IP version supported by the data network name, the processor is further configured to execute the instructions to set the requested PDU type of the PDU session in the process of establishing the PDU session by setting, by the UE in the process of establishing the PDU session, the requested PDU type of the PDU session to an intersection of the IP version requested by the application and the IP version supported by the data network name.

14. The UE of claim 8 , wherein the first application identifier and the second application identifier comprise an application name.

15. A computer program product comprising instructions stored on a non-volatility computer readable medium that, when executed by a processor, cause a user equipment (UE) to:
obtain a UE route selection policy (URSP) for the UE from a policy control function entity, wherein the URSP comprises a
