A COMMUNICATIONS NETWORK AND METHOD FOR SCREENING INCOMING CIRCUIT SWITCHED CALLS

摘要

A communications network (100) and method for screening incoming circuit switched calls (108) directed to a mobile terminal (116) operating in packet switched mode. The communications network (100) includes a circuit switched network (104) and a packet switched network (102). A called party uses the mobile terminal (116) to transmit to the packet switched network (102) a screening list (132) containing at least one listed phone number. The packet switched network (102) uses the screening list (132) to inform the called party whenever an incoming circuit switched call (108) of a calling party has a phone number matching anyone of the listed phone numbers.
