TRANSMISSION CALL PROCESSING CONTROL METHOD OF LAWLESS SUBSCRIBER

摘要

PURPOSE: A method for controlling an origination call processing of an illegal subscriber is provided to omit an unnecessary process of performing a registration notification map operation for reckless retransmitted calls of illegal subscribers, thereby simplifying a processing function and reducing unnecessary system load. CONSTITUTION: A VLR inputs an origination subscriber information request from an MSC(S1). The VLR searches subscriber information stored in a self database(S2). The VLR decides whether origination subscriber information is registered in the self database(S3). If so, the VLR decides whether an ESN transmitted from a mobile station is equal to an ESN stored in the database(S4). If so, the VLR searches an authentication reject item of the database and decides whether the origination subscriber information is illegal(S5). If so, the VLR outputs a response rejection for the origination subscriber information request to the MSC(S6).
