In the second method using the conventional host computer and terminal, the terminal side has a basic control program for the terminal such as communication control and display control, but data and control programs unique to the service are provided. Since it is transferred sequentially from the host computer of the center, various services can be used by changing the center, but it is necessary to always connect to the center while the service is being executed. Therefore, the communication cost of the user is increased and the line utilization rate of the public network is reduced. In addition, the center side needs communication processing with many terminals, which complicates the communication control unit and increases the response time.

The third method using the conventional program change type terminal and the service by the telephone with the display are the personal computer for each service or a medium such as a floppy disk or an IC memory card in which the control program of the telephone is recorded. Need to be stored for each service.

Further, the method of registering the control programs corresponding to various services in the public terminal requires an increase in the storage capacity of the public terminal, and the expansion of the storage capacity is required as the types of services are added.

The present invention has been made in view of the above points, solves the above-mentioned conventional problems, and when a service is used by connecting to a center using a public terminal, a service desired to be used from a plurality of services is provided. An object of the present invention is to provide a service providing system and a service providing method which can be selected and used, improve the line utilization efficiency of a communication network for selecting and executing services, and do not need to manage a control program for each service. To do.

A further object of the present invention is to provide a service providing system and a service providing method capable of executing a large-scale control program with a short response time between a terminal and a service providing center.
