Abstract
Charging systems and associated methods are disclosed that provide correlation across network domains. The charging system includes a plurality of charging functions connected to one or both of an IMS domain and a packet bearer domain, such as a GPRS domain. A first one of the charging functions identifies the charging records for a particular session in the IMS domain based on a charging identifier. The first charging function then selects one of the charging functions on a per-session basis as a correlation charging function for the session, and forwards the identified charging records for the session in the IMS domain to the correlation charging function. A second one of the charging functions selects one of the charging functions on a per-session basis as the correlation charging function for the session, and also forwards charging records for the session in the packet bearer domain to the correlation charging function.
