Patent ID: 8472601

Claim:
A method for controlling a charging of a composite service in a telecommunications network, the composite service comprising an invocation of a constituent service, the telecommunications network comprising a control node for controlling the composite service, a service node for providing the constituent service, and a charging system for performing the charging, and an interface node communicating with the control node, service node and charging system, wherein the interface node implements steps of: receiving, by the interface node from the control node, control information related to the composite service, the control information indicating that the constituent service is invoked in a context of the composite service, intercepting, by the interface node, a first usage report sent by the service node to the charging system, the first usage report comprising charging indicators related to the invocation of the constituent service, generating, by the interface node, a further usage report by modifying a service name and a service identifier of the charging indicators in the first usage report according to the control information, and sending, by the interface node, the further usage report to the charging system to instruct the charging system to perform the charging according to the further usage report.
