Online charging systems (OCS) and methods are disclosed for correlating online charging requests for a session over an IMS network. The OCS stores online charging requests that are received from a network element serving the session in the IMS network. When a new online charging request is received from another network element, the OCS determines whether the new online charging request relates to the same session as any previously-stored online charging requests. If so, the OCS correlates the online charging requests for the session, and determines a new charging rate for the session based on correlated online charging requests and correlation charging rate rules that are stored in the OCS. The OCS then uses the new charging rate to grant new credit quotas for the session.
