Methods for unified billing across independant networks

摘要

A method of generating a unified billing statement common to at least two independent networks is described, where accounting records of a user are collected from at least two networks and a single billing statement encompassing the two networks is generated for the user based on the accounting records. The accounting records may include Call Data Records (CDRs) in a UMTS, Usage Data Records (UDRs) in a cdma2000 system and accounting records of a wireless local area network (WLAN), for example. The accounting records may include user attribute information common to each of the networks. This common user attribute information may be used to generate common billing records which are then used to generate the single, unified billing.
