Caller specific function providing method, involves performing caller specific function by called terminal based on function of transmitted cryptographic secured subscriber-information data of calling party

摘要

The method involves transmitting cryptographic secured subscriber-information data from a terminal of a calling party (TA) to a called terminal when a signaling phase sets up voice communication between the terminals. A caller specific function by the called terminal is performed based on a function of the transmitted cryptographic secured subscriber-information data of the calling party, where the secured subscriber-information data includes a certificate (ZA). The secured subscriber information data of the calling subscriber is evaluated at a receiving side using stored rules. Independent claims are also included for the following: (1) a called terminal comprising a user interface for entering a password or personal identification numbers (2) a computer program having set of instructions for performing a caller specific function providing method (3) a data storage medium having set of instructions for performing a caller specific function providing method.
