Charging systems and methods are disclosed for determining the share of call revenue for multiple entities. One embodiment comprises a charging controller that is coupled to a mobile network and an online charging system. The charging controller receives charging data for a call in the mobile network, and processes the charging data and charging rules to identify entities that have a share in revenue for the call. The charging controller generates a charging request message indicating the entities having a revenue share in the call, and transmits the charging request message to the online charging system to cause the online charging system to determine the revenue share for each of the entities.
