Abstract: In a communications network, it is necessary for client software applications to monitor detail records constructed from messages transmitted in a signalling network (100) associated with the communications network. Prior techniques for delivery of the detail records to the client software applications included separate generation of the detail records for each client software application resulting in duplication of effort in the collection and dissemination of the detail records as well as the prolific number of detail record generation tasks required. The present invention overcomes these disadvantages by having a single generator (200, 410) of detail records per site in the signalling network (100), the delivery of the detail records to the client software applications (400, 402, 710, 712, 718) involving a point-to-multipoint communication.
