Network server

Network server (NESERV, NESERV') for the provision of services in a telephone network (TELENET), wherein the network server (NESERV, NESERV') is provided with a first communications unit (INT1, INT1′) for communication with elements (SSP1, SSP2;

• TE1, TE2) of the telephone network (TELENET),
• characterised in that the network server (NESERV, NESERV') is provided with a database (DB) for storing data in accordance with various subscriber-specific hierarchical data structures, that the network server (NESERV, NESERV') is provided with a first access unit (AU1) which is configured so that it allows subscribers (A) of the telephone network (TELENET), by means of a terminal (IPTE), to specify a subscriber-specific hierarchical data structure in the database (DB) that is assigned to the respective subscriber, that the network server (NESERV, NESERV') is provided with a second access unit (AU2) which is configured so that it stores data received by a terminal (IPTE) of a subscriber (A) in the database (DB) in accordance with this subscriber's respective subscriber-specific hierarchical data structure, and that the network server (NESERV, NESERV') is provided with a third access unit (AU3) which is configured so that, on a data request by one of the terminal (TE1 to TE4) of the telephone network (TELENET), it determines the subscribers (A, B, C) of this terminal (TE1 to TE4), allows the terminal (TE1 to TE4) to read out the data stored in the database (DB) in accordance with the subscriber-specific hierarchical data structure of the detected subscriber (A, B, C) and in so doing sends the read-out data by means of the first communications unit (INT1, INT1′) to elements (SSP1, SSP2;
• TE1 to T24) of the telephone network (TELENET).
