A method for implementing charging communication services is provided, wherein, the charging system includes a charging module and an expression analyzer; the charging module first determines a plurality of basic expression factors, and a user configures expressions based on the expression factors; the charging module reads a communication record, obtains the values of the expression factors by analyzing the communication record, and transmits the values of the expression factors to the expression analyzer; the expression analyzer performs the expression operation assigned with the expression factor values and finally returns the operation result to a charging module; and the charging module searches the corresponding charging rate according to the operation result and calculate the fee. This invention makes the configuration of charging rules more flexible and convenient, raising the development possibility of programs, providing quick support for new service demands, unifying the charging policy description, and simplifying the maintenance work.
