Abstract: PURPOSE: An apparatus and method for authenticating a terminal and processing a call in a private EV-DO are provided to reduce an unnecessary load in a public network DLR(Data Location Register) by processing a call in a private network DLR after obtaining essential session information from the public network DLR when a call is first connected. CONSTITUTION: An AT(Access Terminal) transmits a signal requesting access to a private EV-DO wireless network to a private ANTS(Access Network Transceiver System)(S301). The private ANTS routes the private network access request signal to a pANC(private Access Network Control)(S302). The pANC determines whether the call connection signal is for a private EV-DO wireless network access or for a public EV-DO wireless network access(S303). If the call connection request signal is the private EV-DO wireless network access request signal, the pANC provides a session information request signal(S305). A pDLR(private Data Location Register) determines whether session information for the AT has been stored in a database(S306). If there is no session information on the AT, the pDLR requests session information on the AT from a public DLR of a public EV-DO wireless network(S307). The public DLR searches the session information on the AT and transmits it to the pDLR(S308). The pDLR extracts terminal authentication information, namely, IMSI(International Mobile Station Identity) information, included in the received session information(S309). The pDLR compares the extracted IMSI information of the AT and IMSI information of private network ATs registered in its database(S310). If the IMSI of the AT has been registered in the database, the pDLR stores the session information in the database(S311) and transmits it to the pANC(S312). The pANC allocates a traffic channel to the AT and sets a service(S313), and then, registers at a pPDSN so as to be connected(S314).
