Abstract: PURPOSE: A password call control method in asynchronous network is provided to determine whether to allow a call by comparing an inputted password and a previously registered password, and perform a supplementary service if the passwords are not identical. CONSTITUTION: When a subscriber requests call connection, an HLR(Home Location Register) receives a position information request message from a GMSC(Gateway Mobile services Switching Center) and searches information related to password call permission service for a receiving side subscriber(S200,S201). The HLR checks whether the password call permission service for the receiving side subscriber is active and a password has been registered, and if the password call permission service is not active, the HLR performs a procedure for obtaining a password with an originating side subscriber(S203). The obtained password and a previously registered password are compared. If they are identical, position of the receiving side subscriber is connected(S204,S205). If the two passwords are not identical, it is checked whether a supplementary service has been linked and the linked supplementary service is performed or a call processing is terminated(S206-S208).
