METHOD AND SYSTEM FOR PROVIDING CALLER RELATED INFORMATION TO RECEIVING TERMINAL WITH INTERWORKING BETWEEN COMMUNICATION NETWORKS

摘要

PURPOSE: A method and system for providing caller related information to a receiving terminal with interworking between communication networks are provided to supply to a receiving terminal through inter-network communication the caller-related information between communication network service providers. CONSTITUTION: A caller-related information providing unit requests the caller-related information of an originating terminal from a terminal information server of a PSTN(Public Switched Telephone Network)(S140). The terminal information server extracts the caller-related information(S150), and the caller-related information providing device generates a call connection request signal based on extracted caller related information(S170). If the call connection request signal is received, a mobile communication network forces a receiving terminal to display the caller-related information(S180, S190).
