CALL SETTING UP METHOD BETWEEN ATM PUBLIC NETWORK AND PRIVATE NETWORK USING EXTENDED ADDRESS

摘要

PURPOSE: A call setting up method between an ATM public network and a private network using an extended address is provided to minimize an overhead by extending an ATM name server to comprise public network address information in one host name. CONSTITUTION: A call setting up method between an ATM public network and a private network using an extended address comprises the steps of a confirmation process, a question process, a transmission process, and a setting up process. The confirmation process is to confirm an address of a receiving ATM terminal is stored in a cache of a transmitting ATM terminal, or not. The question process is to ask a name of the receiving ATM terminal to an ATM name server. The transmission process is to transmit extended address information of the receiving ATM terminal to the transmitting ATM terminal. The setting process is to set a call according to the address form.
