INDUCED ANSWERING METHOD AND SYSTEM FOR CIRCUIT SWITCHING-BASED TELEPHONY

摘要

Induced answering method and system for CS-based telephony. A user terminal (5) for communication over a telecommunications network (3) includes at least a CS-telephony device (CSO) for processing CS-based telephony signals (CS1, CS2), the CS-based telephony signals being received and transmitted over a circuit switched bearer service. The user terminal is arranged for receiving an additional answer-related signal (PS1; CS3), the additional answer-related signal being associated with an incoming CS-alert signal (CS1) of an incoming call. Further, the user terminal is arranged for transmitting a response signal or CS-answer signal (CS2) over the circuit switched bearer service in response to information included in, or derived from, the additional answer-related signal.
