Rule engine and charging system based on rule engine in cloud computing platform

Abstract

The invention discloses a rule engine and a charging system. The rule engine comprises a rule library, a work memory zone and an inference engine. The rule library stores a compilable form of a rule; the work memory zone stores a fact and corresponds an objected transmitted thereto; the inference engine comprises a mode adapter, an agenda and an execution engine; the mode adapter decides a rule for execution selection and time for rule execution; the agenda manages an execution order of a rule selected by the mode adaptor; and the execution engine is responsible for rule execution. The rule engine provided by the invention derives from an expert system, is an inference system based on a production rule, uses a predefined rule language to compile a business rule, and separates the business logic from an application, so the business rule is more readable, compilable, and dynamically configurable, thereby meeting complicated and changing requirements. By use of the charging system based on the rule engine in a cloud computing platform, problems of various complicated models in the charging is solved, a problem that a charging rule cannot be flexibly configured is solved and visualization edition of the charging rule is achieved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a charging system based on a rule engine in a cloud computing platform. Background technique [0002] In the prior art, cloud computing billing services are mainly for three categories: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). The complexity of the business model in the above three services, the real-time nature of billing requirements, the variability and customization of billing modules, and various promotional activities from competitors, various cloud computing packages, and new Products, new solutions, etc. all require business systems to have rapid business deployment capabilities. Especially for the billing system, it is necessary to flexibly customize new billing schemes for various packages and solutions. The traditional method is based on hard coding, writing the billing logic into the code or into the data...
