A METHOD FOR SERVICE APPLICATION ACCESSING THE CHARGING SYSTEM, A CHARGING ENGINE AND CHARGING NETWORK THEREOF

摘要

A method for OMA service application accessing the charging system supports the charging for various OMA application services including the charging according to the flow, the time, the content or the frequency; the method fulfills the various requirements, and the main charging logic process function includes the functions of credit control, fee-deduction, service charging, pre-deduction and pre-deduction at multiple times, pre-deduction rollback, etc. There are also a charging engine (200) and a charging network. The charging engine (200) generates the charging request which can be identified by the charging infrastructure and sends to the charging infrastructure to complete fee-deduction according to the corresponding charging fashion determined by the user attribute determined by the user identifier within the charging event and the charging event type after receiving the charging event from the service application server (210), so that the present invention can fulfills the charging requirement for multiple OMA services, and enables the each service to be accessed to the charging network for charging conveniently.
