Abstract

An information input-output system comprises a mobile communication terminal, and a host computer that performs communications with the terminal over a radio transmission line and has a database relating to services that can be provided to the user of the terminal. This system also comprises an input-output gateway server that verifies whether the user is a subscriber who can be provided with a variety of services, and an input-output control unit that receives data from the database over an established line and then outputs the data.

Claims

1. An information input-output device comprising:

a service provision unit which has a database relating to services that can be provided to a user of the device, and provides an output job code for a service to be provided to the user; and

an input-output control unit which receives data from said service provision unit, and the output job code, and outputs data associated with the output job code, wherein

data in the database is read out through operation from said input-output control unit; and

said service provision unit determining the output job code for the user who can be provided with the service, said input-output control unit receives the data, the output job code, and then outputs the data associated with the output job code.

2. An input-output control method comprising the steps of:

receiving data from a service provision unit corresponding to a data output process requested by a user;

receiving an output job code from said service provision unit corresponding to the data output process;

reading said data from an input-output control unit; and

outputting the data associated with the output job code.

3. A computer readable storage medium containing a computer readable code for operating a computer to perform an input-output control method, said input-output control method comprising the steps of:

receiving data from a service provision unit corresponding to a data output process requested by a user;

receiving an output job code from said service provision unit corresponding to the data output process;

reading said data from an input-output control unit; and

outputting the data associated with the output job code.
