Policy management based routing and filtering of charging data records in an Internet Protocol Multimedia Subsystem

摘要

A system and method for policy management based routing and filtering of charging data records (CDRs) used to bill for services provided by an Internet Protocol Multimedia Subsystem (IMS). The system includes a Vortex Rule Engine (VRE), which includes handling instructions for routing CDRs, and a CDR routing unit. The CDR routing unit receives a CDR, sends a query to the VRE for handling instructions relating to the received CDR, and routes the CDR based on the handling instructions received from the VRE in response to the query. The method includes the steps of receiving a CDR from a charging data function (CDF), sending a query relating to the CDR to a vortex rule engine (VRE), and routing the CDR to a storage location based on instructions received from the VRE.
