Embodiment Construction

[0075] The inventor noticed during the invention that:

[0076] At present, the strategy issued by the core network is currently obtained by AMF and SMF network elements at the granularity of network elements to PCF, without considering the support capabilities of terminals, slices, and DNN (Data Network Name, Data Network Name), as follows UEpolicy is used as an example for description.

[0077] 1. Introduction to UE policy.

[0078] The user identification message (UE policy) is delivered to the terminal by the PCF, and is mainly used to guide the terminal to register and access and route selection when initiating a session request. It mainly includes the following two strategies:

[0079] 1) Access Network Discovery&Selection Policy (ANDSP, access network discovery and selection policy): used for UE to select non-3GPP network access.

[0080] 2) UE Route Selection Policy (URSP, UE routing selection policy): used for UE to associate related applications and PDU sessions, ...

Abstract

The invention discloses a policy notification method and device, and a storage medium. The method comprises the following steps: receiving a registration and mobility update request of a terminal; and the AMF or the SMF sends a policy request issued by the core network to the PCF based on one of the following information or a combined switch: a user identifier, a slice and a DNN according to the indication. By adopting the method and the device, the function of acquiring the UE Policy / AM Policy / SM Policy through the PCF does not need to be set to be opened or closed by the whole AMF or SMF, signaling interaction between the AMF or SMF and the PCF can be reduced, and signaling resources are saved. According to the invention, the support capability of the terminal, the session capability of the slice / DNN and the capability of flexibly opening / closing an interaction strategy between the AMF or SMF and the PCF can be considered, and different service scenes and requirements can be met. The application range is wide, the strategy UE policy issued by the existing core network can be expanded to the AM policy, the SM policy and various policy information of subsequent inventions, and the expandability is high.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a policy notification method, device and storage medium. Background technique [0002] At present, the policies issued by the core network include UE policy (UE policy; UE: User Equipment, User Equipment), AM policy (AM policy; AMF: Access and Mobility Management Function, Access and Mobility Management Function) and SM policy (SM policy; SMF: session management function, Session Management Function), these policies are currently acquired by AMF (access and mobility management function, Access and Mobility Management Function), SMF (session management function, Session Management Function) network element at the network element granularity A request is initiated to a PCF (Policy Control Function). [0003] The disadvantage of the existing technology is that AMF or SMF can only enable or disable the function of obtaining UE policy, AM policy, and SM policy ...
