3. The system according to claim 1, further comprising a data service node connected to the hub to provide data services only to the terminal of the private wireless network.

4. The system according to claim 1, wherein, in a case where the terminal of the private wireless network is also used in the public wireless network, the data location register stores terminal information of both the private wireless network and the public wireless network in the terminal and assigns the UATI of the private wireless network to the terminal when the terminal is located within a range of a predetermined base station.

5. The system according to claim 1, wherein the data location register assigns the UATI of the private network to a corresponding terminal, when the terminal is located within a predetermined base station in a predetermined time zone.

6. The system according to claim 1, wherein the hub discriminates between private wireless network services and public wireless network services by means of the UATIs received from the terminals in connecting a call.

7. The system according to claim 1, wherein, in performing call out to the public wireless network, the hub originates a call through another hub belonging to the public wireless network.

8. The system according to claim 1, wherein the private authentication system further has a database for authentication of the terminal of the public wireless network.

9. A call out method by a high-speed wireless data system, the system comprising a hub and a base station controller, the hub discriminating between public wireless network services and private wireless network services in performing routing, the base station controller performing a control operation for providing the private wireless network services when the hub requires the private wireless network services, the method comprising the steps of:

when a predetermined terminal demands a call out from through a base station, the hub checking an UATI and a destination address received from the terminal by the hub to determine whether private wireless network services are required or not;

when private wireless network services are required, the hub connecting a call to the base station and the base station controller;

the base station controller checking through a private authentication system whether the terminal has been authenticated or not; and

when the terminal has been authenticated, the base station controller directing the call to the requested destination address to perform communication.

10. The method according to claim 9, further comprising a step of recording a location of the terminal upon completion of the communication.

11. The method according to claim 9, wherein, in the step of determining whether private wireless network services are required or not, it is concluded that private wireless network services are required, when the destination address received from the terminal is an address belonging to the private wireless network.

12. The method according to claim 9, wherein the UATI received from the terminal which demanded the call out enables determination of whether the terminal belongs to the private wireless network or the public wireless network.

13. The method according to claim 9, further comprising a step of the hub performing a process for providing public wireless network services when the public wireless network services are required as a result from the checking of the UATI and the destination address of the terminal received through the base station.

14. The method according to claim 13, further comprising a step of the hub transmitting the UATI and the destination address of the terminal demanding the call out to another hub of the public wireless network for providing public wireless network services when the public wireless network services are required.
