Pay information distribution system

An information data distribution method comprising:

• a step of distributing information data stored in a server to a data communication terminal via a communication network;
• a step of displaying types of information data, which said server stores, on a display unit of said data communication terminal, and of prompting a user to select;
• a step of displaying a screen for accepting receipt of distribution of the information data on said display unit on condition that billing is performed, and for prompting said user to accept when said user selects types of information data displayed on said display unit;
• a step of distributing information data selected by said user to said data communication terminal from said server after said user inputs acceptance in said data communication terminal;
• a step of transmitting control information data, showing distribution is completed, to said server from said data communication terminal when all of said selected information data is received by said data communication terminal, and of displaying on said display unit, all of said selected information data is received;
• and
• a step of billing said user on condition that said server receives said control information data.

An information data distribution system comprising:

• a server distributes to a data communication terminal via a communication network, information data stored in a server;
• said server distributes said information data to said data communication terminal according to a request from said data communication terminal, and bills a user of said data communication terminal on condition that control information data, showing distribution of said information data is completed, is received from said data communication terminal;
• and
• said data communication terminal notifies a user that reception of said information data is completed when reception of said information data is completed after transmitting said control information data to the server.

A data communication terminal comprising:

• a transmission and reception unit for performing reception of information data stored in a server, and transmission of control information data showing distribution of said information data is completed via a communication network;
• a notification unit for performing to notify a user with regard to reception of said information data;
• and
• a control unit for notifying said user that reception of said information data is completed by utilizing said notification unit after detecting that reception of said information data is completed, generating said control information data, and transmitting said control information data to said server by utilizing said transmission and reception unit.

An information data reception method comprising:

• a step of receiving a total amount of information data transmitted and distributed from a server;
• a step of starting reception of said information data stored in a server, and of evaluating an amount of received integrated information data during reception of said information data after receiving total amount of information data;
• a notification step of evaluating progress status which is later than actual progress status of reception of said information data by the amount of said integrated information data and the total amount of said information data during reception of said information data, and notifying a user of evaluated progress status;
• a step of transmitting a billing request with regard to said information to a server after reception of said information is completed;
• and
• a step of notifying said user that reception of said information is completed after said billing request is transmitted.

A program for performing control of a data communication terminal by computer comprising:

• a step of receiving total amount of information data transmitted and distributed from a server;
• a step of starting reception of said information data;
• and of evaluating amount of received integrated information data during reception of said information data after receiving total amount of information data;
• a notification step of evaluating progress status which is later than actual progress status of reception of said information by the amount of said integrated data and the total amount of said information data during reception of said information data, and notifying a user of evaluated progress status;
• a step of transmitting a billing request with regard to said information data to a server after reception of said information data is completed;
• and
• a step of notifying said user that reception of said information data is completed after said billing request is transmitted.

A recording medium, readable by computer, for recording a program for performing control of a data communication terminal comprising:

• a step of receiving total amount of information data transmitted and distributed from a server;
• a step of starting reception of said information data, and evaluating amount of received integrated information data during reception of said information data after receiving total amount of information data;
• a notification step of evaluating progress status which is later than actual progress status of reception of said information data by the amount of said integrated information data and the total amount of said information data during reception of said information data, and of notifying a user of evaluated progress status;
• a step of transmitting a billing request with regard to said information data to a server after reception of said information data is completed;
• and
• a step of notifying said user that reception of said information data is completed after said billing request is transmitted.

An information data distribution method wherein:

• a server generating random numbers, evaluates second total amount of data based on first total amount of data showing total amount of information data to be distributed to a data communication terminal from a server and said random numbers, and starts to transmit said information data to said data communication terminal after transmitting said first total amount of information data and said second total amount of information data to said data communication terminal;
• and
• said data communication terminal evaluates amount of received integrated information data of said information data during reception of said information data, evaluates progress status which is later than actual progress status of said information data by amount of said integrated information data and total amount of said second information data, notifies a user of evaluated progress status, and determines whether reception of said information data is completed or not by the total amount of said first information data and the amount of said integrated information data;
• and
• said data communication terminal transmits to a server, a billing request with regard to said information data after completing reception of said information data.

18:

• A server comprising:
• a control unit for generating random numbers, and evaluating total amount of second information data based on said random numbers and total amount of first information data showing total amount of information data which is distributed to a data communication terminal;
• and
• a transmission unit which starts to transmit said information data after transmitting to said data communication terminal, the total amount of said first information data and the total amount of said second information data.
