MOBILE NETWORK OPERATOR AND MOBILE VIRTUAL NETWORK OPERATOR WITH COOPERATIVE CHARGING FUNCTIONS WHICH RECORD SERVICE RELATED INTENDED ACTIONS AND INDICATIONS OF SUCCESS

A first charging function (CHF) in a network node of a first communications network, receives a charging data request from a charging trigger function. The charging data request requests quota for a service provided by the network function. The first CHF determines that a second CHF of a second communications network needs to be contacted related to the service. The first CHF opens a charging data record (CDR) and adds charging data related to the service and an indication of intent to contact the second CHF to perform the recording related to the service and at least one of the account balance management related to the service and the rating related to the service. The first CHF sends the charging data request to the second CHF, and receives a charging data response indicating whether the second CHF completed the account balance management and/or the rating, and updates the CDR.
