OCF – Online Charging Function

In the 3GPP IMS (IP Multimedia Subsystem) architecture, the OCF forms an integral part of the online charging system, determining whether or not, from a billing perspective, the customer is allowed to access network resources or services. The EBCF (Event Based Charging Function) and SBCF (Session Based Charging Function) are key elements of the OCF.
