PRIVATE WIRELSS 1X CDMA EV-DO AND DATA SERVICE METHOD USING THE SAME, CONCERNED WITH SIMULTANEOUSLY PROVIDING BOTH PUBLIC AND PRIVATE WIRELESS 1X CDMA EV-DO NETWORK SERVICES TO USERS

摘要

PURPOSE: A private EV-DO and a data service method using the same are provided to simultaneously provide both public and private wireless EV-DO network services to users by using a CDMA 1x EV-DO type mobile terminal. 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 authenticates the AT(S309). If the AT has been registered for the private EV-DO wireless network(S310), the pDLR stores the terminal session information transmitted from the public DLR in the database(S311) and then transmits it to the pANC(S312). The pANC allocates a traffic channel and processes a call(S313).
