Communication method and device

Abstract

The invention discloses a communication method and a communication device, which are used for solving the problem of limited system functions caused by limited corresponding actions executed by a corenetwork user plane network element according to rules in the prior art. When the core network control plane network element determines that the core network user plane network element needs to be triggered to carry out bearer connection; and sending a bearer connection request message to the core network user plane network element, creating at least one first EAR by the core network user plane network element according to at least one piece of first EAR creation information included in the bearer connection request message, and correspondingly storing the created at least one first EAR and the identifier of the first EAR. Through the method, the core network user plane network element can execute related actions corresponding to the execution rules except the FAR, the URR and the QER, sothat the aim of extending the action rules is fulfilled, and the integrity of system functions can be improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] The 3GPP standard 29244 version 100 describes the Sx interface used to define the interface between the 4G core network (evolved packetcore, EPC) control plane network element and the user plane network element, and the 5G core network control plane (next generation controlplane, NG-CP) network element When the user goes online or updates, various rules and policy information related to the user will be delivered to the 5G core network user plane (next generation user plane, NG-UP) network elements through this interface. [0003] Wherein, when the core network control plane network element sends a bearer establishment request message to the core network user plane network element, the bearer establishment request message will carry a packet detection rule (packet detection rule, PDR), forwarding...
