Method for providing data for a querying communication terminal

摘要

The invention relates to a method for providing data relating to a user of a communication terminal for a querying communication terminal. The method involves a network node in a telecommunication network receiving a data query message from the querying communication terminal, the data query message being used to transmit an identifier for the querying communication terminal or for a user of the querying communication terminal. A data store is read to determine whether the received identifier is associated with a group of communication subscribers, and the existence of such an association prompts the network node to ascertain which information types are associated with this group. The data which relate to the user of the communication terminal and are connected with these information types are then provided for the querying communication terminal.
