Embodiment Construction

[0036] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application.

[0037] figure 1 A schematic diagram of a 5G communication system provided by an embodiment of the present application is shown. In the 5G mobile network architecture, the core network includes control plane (control plane) network elements and user plane (user plane) network elements. Among them, the control plane network element is the traditional control network element of the third generation partnership project (3GPP), the mobility management entity (mobility management entity, MME) and the control plane function of the serving gateway (serving gateway, SGW). A unified control plane formed by merging control plane functions of a packet data network gateway (packet data network gateway, PGW), etc. The user plane network element can implement the user plane functions of the SGW and PGW (...

Abstract

The present application provides a policy-related communication method, including: a network element with a policy control function determines indication information according to identification information of a first event; and sends the indication information to a control plane network element. The indication information is used to indicate that: the control plane network element does not perform subsequent operations associated with the first terminal until the control plane network element receives the policy information of the first terminal from the policy control function network element. The control plane network element is a session management function network element or a mobility management function network element. Through this solution, the signaling processing efficiency of the control plane network element is improved, thereby improving user experience.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a policy-related communication method, device and system. Background technique [0002] A core network (5G core, 5GC) of a fifth-generation (the 5th-Generation, 5G) communication network supports a packet data unit (packet data unit, PDU) connection service. For example, the service provides PDU interaction between a user equipment (user equipment, UE) and a data network (data network, DN). The PDU connection service is supported by the PDU session. For example, a PDU session may be established at the UE's request. [0003] When the quality of service (quality of service, QoS) interacted between the UE and the network side needs to be modified, the UE or the network side will request to initiate a PDU session modification process. In this process, session management policy modification (sessionmanagement policy modification) will be involved. In addition, in pro...
