ORIGINATION CONTROL SYSTEM IN AN ASYNCHRONOUS IMT-2000 NETWORK AND A METHOD THEREOF, PARTICULARLY FOR CONNECTING A CALL BETWEEN AN ORIGINATION TERMINAL AND A DESTINATION TERMINAL WHEN A PASSWORD INPUTTED BY THE ORIGINATION TERMINAL IS IDENTICAL TO A PASSWORD PREVIOUSLY SET BY THE DESTINATION SUBSCRIBER

摘要

PURPOSE: An origination control system and method in an asynchronous IMT-2000 network are provided to allow a callee to refuse a call by preventing an erroneously received call or a prank call by controlling a caller side. CONSTITUTION: A Node B(20) performs communications in a radio interface with a mobile terminal(10). An RNC(Radio Network Controller)(30) controls the Node B(20). An MSC(Mobile Switching Center)(60) connected with the RNC(30) handles registration of a location of a subscriber, and controlling, processing and exchanging a line call. An HLR(Home Location Register)(70) manages subscriber location information and supplementary service information. An SGSN(Serving GPRS Support Node)(40), connected between the RNC(30) and an IP network, performs a function of controlling and processing a packet call of a mobile terminal(10). A GGSN(Gateway GPRS Support Node)(50) connected with the SGSN(40) provides a packet data service.
