Charging method, device and system

Abstract

The embodiment of the invention discloses a charging method and a related product. The charging method comprises the following steps that according to an industry user identifier and a slice user identifier contained in a charging rule, a charging triggering CTF device determines that an industry user charging session exists between the CTF device and a charging function CHF device; when a charging triggering condition is satisfied, a charging request is sent to the CHF device through an industry user charging session existing between the CTF device and the CHF device according to the chargingrule, and the charging request carries the industry user identifier, the slice network instance identifier and charging data. By multiplexing existing industry user charging sessions, online sessionsof a CHF device and a CTF device can be reduced, and the resource utilization rate is increased.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a charging method, device and system. Background technique [0002] In 5G network technology, the most important concept is the concept of network slicing. The essence of network slicing is to run multiple virtual networks on the shared physical network infrastructure. Each virtual network is divided according to different service requirements, such as delay, bandwidth, security, and reliability, so as to flexibly respond to different Network application scenarios. These network slices can be rented by some industry customers with specific needs, so as to provide better services for end users. [0003] The most important application scenarios of 5G include enhanced mobile broadband, ultra-high reliability and low-latency communication, and large-scale connection machine-type communication. These scenarios have very different network characteristic requireme...

Problems solved by technology

[0004] At present, in the 5G scenario, industry users can use network slicing technology to rent operators' resources to carry out services. At this time, the operator's billing system needs to bill industry users and individual users. In the current billing process framework Next, the charging trigger function (charging trigger function, CTF) device and the charging function (charging function, CHF) device are performing charging processing, which need to establish an online session for each user, which can only be performed on the basis of the PDU session Billing, if there are a large number of individual users in this industry, a large number of online sessions and charging requests need to be generated between the billing trigger device and the billing function device, which will generate a huge network resource occupation, and at the same time Billing triggers and billing function devices are often under high load
