Abstract

The present disclosure provides a method in a Next Generation Core Control Function (NG-CCF) node for communication with a Next Generation Policy Control Function (NG-PCF) node. The method comprises: communicating network related parameters with the NG-PCF node via a direct interface between the NG-CCF node and the NG-PCF node.

First claim

The invention claimed is:

1. A method in a Next Generation Core Control Function (NG-CCF) node for communication with a Next Generation Policy Control Function (NG-PCF) node, the method comprising:
communicating network related parameters with the NG-PCF node via a direct interface between the NG-CCF node and the NG-PCF node, wherein the NG-CCF node is an Access and Mobility Management Function (AMF) node, and wherein communicating the network related parameters comprises:
transmitting, to the NG-PCF node, a request for a mobility policy associated with one or more of Location-Based Service (LBS) and Next Generation User Plane (NG-UP) selection; and
receiving the mobility policy from the NG-PCF node.

2. The method of claim 1 , wherein the mobility policy is further associated with one or more of mobility preference information handling and Radio Access Technology (RAT)/Frequency Selection Priority (RFSP) selection.

3. The method of claim 1 , wherein communicating the network related parameters further comprises:
receiving, from the NG-PCF node, a request to modify the mobility policy associated with one or more of the LBS and the NG-UP selection.

4. The method of claim 1 , wherein the direct interface is further configured to serve as a Gx interface.

5. A Next Generation Core Control Function (NG-CCF) node for communication with a Next Generation Policy Control Function (NG-PCF) node, the NG-CCF node comprising a transceiver, a processor, and memory, the memory containing instructions to cause the processor to:
communicate network related parameters with the NG-PCF node via a direct interface between the NG-CCF node and the NG-PCF node, wherein the NG-CCF node is an Access and Mobility Management Function (AMF) node, and wherein to communicate the network related parameters, the instructions further cause the processor to:
transmit, to the NG-PCF node, a request for a mobility policy associated with one or more of Location-Based Service (LBS) and Next Generation User Plane (NG-UP) selection; and
receive the mobility policy from the NG-PCF node.

6. The NG-CCF node of claim 5 , wherein the mobility policy is further associated with one or more of mobility preference information handling and Radio Access Technology (RAT)/Frequency Selection Priority (RFSP) selection.

7. The NG-CCF node of claim 5 , wherein to communicate the network related parameters, the instructions further cause the processor to receive, from the NG-PCF node, a request to modify the mobility policy associated with one or more of the LBS and the NG-UP selection.

8. The NG-CCF node of claim 5 , wherein the direct interface is further configured to serve as a Gx interface.

9. A method in a Next Generation Policy Control Function (NG-PCF) node for communication with a Next Generation Core Control Function (NG-CCF) node, the method comprising:
communicating network related parameters with the NG-CCF node via a direct interface between the NG-CCF node and the NG-PCF node, wherein the NG-CCF node is an Access and Mobility Management Function (AMF) node, and wherein communicating the network related parameters comprises:
receiving, from the NG-CCF node, a request for a mobility policy associated with one or more of Location-Based Service (LBS) and Next Generation User Plane (NG-UP) selection; and
transmitting the mobility policy to the NG-CCF node.

10. The method of claim 9 , wherein the mobility policy is further associated with one or more of mobility preference information handling and Radio Access Technology (RAT)/Frequency Selection Priority (RFSP) selection.

11. The method of claim 9 , wherein communicating the network related parameters further comprises:
transmitting, to the NG-CCF node, a request to modify the mobility policy associated with one or more of the LBS and the NG-UP selection.

12. The method of claim 9 , wherein the direct interface is further configured to serve as a Gx interface.

13. A Next Generation Policy Control Function (NG-PCF) node for communication with a Next Generation Core Control Function (NG-CCF) node, the NG-PCF node comprising a transceiver, a processor, and memory, the memory containing instructions to cause the processor to:
communicate network related parameters with the NG-CCF node via a direct interface between the NG-CCF node and the NG-PCF node, wherein the NG-CCF node is an Access and Mobility Management Function (AMF) node, and wherein to communicate the network related parameters, the instructions further cause the processor to:
receive, from the NG-CCF node, a request for a mobility policy associated with one or more of Location-Based Service (LBS) and Next Generation User Plane (NG-UP) selection; and
transmit the mobility policy to the NG-CCF node.

14. The NG-PCF node of claim 13 , wherein the mobility policy is further associated with one or more of mobility preference information handling and Radio Access Technology (RAT)/Frequency Selection Priority (RFSP) selection.

15. The NG-PCF node of claim 13 , wherein to communicate the network related parameters, the instructions further cause the processor to transmit, to the NG-CCF node, a request to modify the mobility policy associated with one or more of the LBS and the NG-UP selection.

16. The NG-PCF node of claim 13 , wherein the direct interface is further configured to serve as a Gx interface.
