Service providing system, and client, server, and program for the same

摘要

A service providing system includes a providing server that provides a service, and a client that receives the service. The providing server includes a first receiving system that receives a request signal for requesting to provide the service, a first sending system that sends a response signal for providing the service in response to the request signal being received, and a time information adding system that adds time information representing timing at which a next request signal is to be sent to the response signal that is sent from the first sending system when requesting the client to continuously send the request signal. The client includes a second sending system that sends the request signal to the providing server, a second receiving system that receives the response signal, and a control system that controls the sending system to send the request signal at the timing represented by the time information added to the received response signal.
