Abstract

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.

a first sending system configured to send a response signal for providing the service to the client in response to the request signal being received by the first receiving system; and

a time information adding system configured to add time information that represents 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 for requesting to provide the service, and

wherein the client includes;

a second sending system configured to send the request signal to the providing server;

a second receiving system configured to receive the response signal sent from the providing server; and

a control system configured to control the second sending system to send the request signal at the timing represented by the time information included in the response signal received by the second receiving system.

2. The service providing system according to claim 1,

wherein the providing server further includes a database storing the time information corresponding to each of processes to be executed while providing the service associated with each of the processes, and

wherein the time information adding system is configured to judge which process among the processes to be executed while providing the service the response signal is to be sent from the first sending system in, and add the time information stored in the database associated with the process specified by the judgment to the response signal.

3. The service providing system according to claim 1,

wherein the providing server further includes:

a load rate detecting system configured to detect a rate of a load for a processing capacity of the providing server;

a load rate judging system configured to judge which range among a plurality of ranges predetermined on the basis of a level of the rate of the load for the processing capacity of the providing server the rate detected the load rate detecting system is in; and

a database in which the time information determined depending on each of the plurality of ranges is stored associated with each of the plurality of ranges, and

wherein the time information adding system is configured to determine the time information stored associated with the range specified by the load rate judging system in the database as the time information to be added.

4. A service providing system, comprising:

a providing server configured to provide at least one service; and

a client configured to receive the at least one service to be provided from the providing server,

wherein the providing server includes;

a starting command sending system configured to return a first execution command for instructing to execute a process to be executed by the client for starting to provide a service, in response to a starting request for requesting to start to provide the service being received from the client;

a continuing command sending system configured to sequentially return one of second execution commands for instructing to execute a corresponding one of processes to be executed by the client to receive the service to be provided every time receiving a continuing request for requesting to continue to provide the service from the client until having returned all of the second execution commands corresponding to all of the processes to be executed by the client to receive the service to be provided after the starting command sending system has returned the starting command; and

a time information adding system configured to add time information that represents timing at which a next continuing request is to be sent to the second execution command returned from the continuing command sending system when requesting the client to continuously send the continuing request for requesting to continue to provide the service, and

wherein the client includes;

a starting request sending system configured to send the starting request to the providing server;

a continuing request sending system configured to send the continuing request for requesting to continue to provide the service to the providing server, in response to the one of the processes corresponding to the second execution command having been completed in the case where the providing server has started to provide the service based on the starting request being sent from the starting request sending system; and

a process executing system configured to execute a process corresponding to one of the first execution command returned by the starting command sending system in response to the starting request being sent from the stating request sending system and the second execution command returned by the continuing command sending system in response to the continuing request being sent from the continuing request sending system, and

wherein the continuing request sending system is configured to send the continuing request to the providing server in accordance with the time information added to the second execution command, when the process corresponding to the second execution command has been completed.

5. The service providing system according to claim 4,

wherein the providing server further includes a database storing the time information corresponding to each of processes to be executed while providing the service associated with each of the processes, and

wherein the time information adding system is configured to judge which process among the processes to be executed to receive the service the second execution command is to be sent from the continuing command sending system in, and add the time information stored in the database associated with the process specified by the judgment to the second execution command returned by the continuing command sending system.

6. The service providing system according to claim 4,

wherein the providing server further includes:

a load rate detecting system configured to detect a rate of a load for a processing capacity of the providing server;

a load rate judging system configured to judge which range among a plurality of ranges predetermined on the basis of a level of the rate of the load for the processing capacity of the providing server the rate detected the load rate detecting system is in; and

a database in which the time information determined depending on each of the plurality of ranges is stored associated with each of the plurality of ranges, and

wherein the time information adding system is configured to determine the time information stored associated with the range specified by the load rate judging system in the database as the time information to be added.
