A telecommunications network generally represented by service switching points (SSP) (2) and digital local exchanges (DLE) (3), includes a service management platform (SMP) (1). The SMP (1) provides management of account calling, for example using calling cards. Each card call results in the establishment of a call handling session within the SMP (1), the call handling session comprising a number of service function blocks the sequence being selected in dependence upon the type of card in use. Session context data is established in respect of each call handling session, some of the data therein being derived from the card type while other data therein is modified at points throughout the call by respective service function blocks. <IMAGE> |
