Description

Charging management method, device and system

Technical Field

The present application relates to the field of communications technologies, and in particular, to a charging management method, device, and system.

Background

The fifth generation (5rd generation, 5G) converged charging service is a charging standard mainly formulated by the third generation partnership project (3 GPP) organization for 5G data networks, and is used to provide a reliable charging solution for 5G network operators. As shown in fig. 1, a 5G convergence charging service architecture defined for 3GPP includes a Network Function (NF) and a charging function (CHF). The NF integrates a Charging Trigger Function (CTF), and the serving interface provided by the CHF is Nchf. Wherein, NF is the consumer of the convergence charging service, CHF is the producer of the convergence charging service, and CTF mainly realizes the triggering function of the charging event.

The 3GPP currently defines two fusion charging scenarios, event-based charging and session-based charging, respectively. However, the scenario in the fusion charging flow defined by the existing 3GPP is relatively simple, and the message processing in the normal scenario of the Nchf interface link is mainly considered. In the abnormal scene processing, the 3GPP only specifies a failure handling (failure handling) flag under the CHF, and instructs the NF to perform the action processing in the abnormal scene. The failure handling action includes: deactivation (termination), authorization to continue use (continue) and deactivation after retry (retry _ and _ termination). Wherein the deactivation action affects the user's data experience using 5G. And the authorization is directly used to continue using the action, and the protocol does not make clear how to charge subsequently. Therefore, there is no reliable solution for ensuring that the terminal user is not affected to use the 5G data network and the operator is not affected to accurately deduct the fee from the terminal user during the link from nf (ctf) to CHF is interrupted.
