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

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, comprising:
communicating network related parameters with the NG-PCF node via a direct interface between the NG-CCF node and the NG-PCF node.

2 . The method of claim 1 , wherein the network related parameters are associated with a mobility-based policy feature.

3 . The method of claim 2 , wherein said communicating comprises:
transmitting to the NG-PCF node a request for a mobility policy associated with one or more of Location-Based Service, Next Generation User Plane (NG-UP) selection, Radio Access Technology (RAT)/Frequency Selection Priority (RFSP) selection and mobility preference information handling; and receiving the mobility policy from the NG-PCF node.

4 . The method of claim 2 , wherein said communicating comprises:
receiving from the NG-PCF node a request to modify a mobility policy associated with one or more of LBS, NG-UP selection, RFSP selection and mobility preference information handling.

5 . The method of claim 1 , wherein the NG-CCF node is an Access and Mobility Management Function, AMF, node.

6 . A Next Generation Core Control Function (NC-CCF) node for communication with a Next Generation Policy Control Function (NG-PCF) node, comprising a transceiver, a processor, and a 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.

7 . The NG-CCF node of claim 6 , wherein the network related parameters are associated with a mobility-based policy feature.

8 . The NG-CCF node of claim 7 , wherein 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), Next Generation User Plane (NG-UP) selection, Radio Access Technology (RAT)/Frequency Selection Priority (RFSP) selection and mobility preference information handling; and receive the mobility policy from the NG-PCF node.

9 . The NG-CCF node of claim 7 , wherein the instructions further cause the processor to receive from the NG-PCF node a request to modify a mobility policy associated with one or more of LBS, NG-UP selection, RFSP selection and mobility preference information handling.

10 . The NG-CCF node of claim 6 , wherein the NG-CCF node is an Access and Mobility Management Function, AMF, node.

11 . (canceled)

12 . A method in a Next Generation Policy Control Function (NG-PCF) node for communication with a Next Generation Core Control Function (NG-CCF) node, comprising:
communicating network related parameters with the NG-CCF node via a direct interface between the NG-CCF node and the NG-PCF node.

13 . The method of claim 12 , wherein the network related parameters are associated with a mobility-based policy feature.

14 . The method of claim 13 , wherein said communicating comprises:
receiving from the NG-CCF node a request for a mobility policy associated with one or more of Location-Based Service (LBS), Next Generation User Plane (NF-UP) selection and/or Radio Access Technology (RAT)/Frequency Selection Priority (RFSP) selection and mobility preference information handling; and transmitting the mobility policy to the NG-CCF node.

15 . The method of claim 13 , wherein said communicating comprises:
transmitting to the NG-CCF node a request to modify a mobility policy associated with one or more of LBS, NG-UP selection, RFSP selection and mobility preference information handling.

16 . The method of claim 12 , wherein the NG-CCF node is an Access and Mobility Management Function, AMF, node.

17 . A Next Generation Policy Control Function (NG-PCF) node for communication with a Next Generation Core Control Function (NG-CCF) node, comprising a transceiver, a processor, and a 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.

18 . The NG-PCF node of claim 17 , wherein the network related parameters are associated with a mobility-based policy feature.

19 . The NG-PCF node of claim 18 , wherein 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), Next Generation User Plane (NG-UP) selection and/or Radio Access Technology (RAT)/Frequency Selection Priority (RFSP) selection and mobility preference information handling; and transmit the mobility policy to the NG-CCF node.

20 . The NG-PCF node of claim 18 , wherein the instructions further cause the processor to transmit to the NG-CCF node a request to modify a mobility policy associated with one or more of LBS, NG-UP selection, RFSP selection and mobility preference information handling.

21 . The NG-PCF node of claim 17 , wherein the NG-CCF node is an Access and Mobility Management Function, AMF, node.

22 . (canceled)

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

24 . The NG-CCF node of claim 6 , wherein the direct interface is further configured to serve as a Gx interface.

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

26 . The NG-PCF node of claim 17 , wherein the direct interface is further configured to serve as a Gx interface.
