Abstract

Claims (39)

1. A method comprising:

performing a registration procedure for a user equipment (UE);

performing a session establishment procedure for the UE;

receiving an N4 rule generated by a session management node from the session management node,

wherein the N4 rule includes information related to a change of a service function chaining (SFC) path,

wherein the information related to the change of the SFC path is generated by the session management node or by a policy control node, based on UE power consumption analytics,

wherein the UE power consumption analytics are generated by a network data analytics node, based on information related to power consumption of the UE collected from the UE,

wherein the UE power consumption analytics include at least one of a statistic value or a prediction value for efficiency of the SFC path that is changed depending on whether a specific enabler is used;

determining the SFC path based on the information related to the change of the SFC path; and

communicating with the UE based on the determined SFC path.

2. The method of claim 1 , wherein the method is performed by a network node supporting an SFC, and

wherein the network node supporting the SFC is a user plane node.

3. The method of claim 1 , wherein the method is performed by a network node supporting an SFC, and

wherein the network node supporting the SFC is a network node different from a user plane node, and is located together with the user plane node or located separately from the user plane node.

4. The method of claim 1 , wherein the information related to the power consumption of the UE includes information on a battery level of the UE.

5. The method of claim 1 , wherein the policy control node generates a Policy and Charging Control (PCC) rule including the information related to the change of the SFC path.

6. The method of claim 1 , wherein the information related to the change of the SFC path includes at least one of an index or an indicator associated with an SFC path change rule or a pre-configured SFC change rule.

7. The method of claim 1 , wherein the SFC path is associated with at least one enabler.

8. The method of claim 1 , wherein the UE communicates with at least one of a mobile device, a network and/or an autonomous vehicle other than the UE.

9. A network node comprising:

at least one transceiver;

at least one processor; and

at least one memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:

performing a registration procedure for a user equipment (UE);

performing a session establishment procedure for the UE;

receiving an N4 rule generated by a session management node from the session management node,

wherein the N4 rule includes information related to a change of a service function chaining (SFC) path,

wherein the information related to the change of the SFC path is generated by the session management node or by a policy control node, based on UE power consumption analytics,

wherein the UE power consumption analytics are generated by a network data analytics node, based on information related to power consumption of the UE collected from the UE,

wherein the UE power consumption analytics include at least one of a statistic value or a prediction value for efficiency of the SFC path that is changed depending on whether a specific enabler is used;

determining the SFC path based on the information related to the change of the SFC path; and

communicating with the UE based on the determined SFC path.

10. The network node of claim 9 , wherein the network node supports an SFC, and

wherein the network node supporting the SFC is a user plane node.

11. The network node of claim 9 , wherein the network node supports an SFC, and

wherein the network node supporting the SFC is a network node different from a user plane node, and is located together with the user plane node or located separately from the user plane node.

12. The network node of claim 9 , wherein the information related to the power consumption of the UE includes information on a battery level of the UE.

13. The network node of claim 9 , wherein the information related to the change of the SFC path includes at least one of an index or an indicator associated with an SFC path change rule or a pre-configured SFC change rule.

14. The network node of claim 9 , wherein the SFC path is associated with at least one enabler.
