Benefits of technology

This approach guarantees that either the content validation or payment processing is completed, preventing issues like duplicate billing or unvalidated content, thus ensuring transaction integrity and user satisfaction.

Problems solved by technology

At this time point, the content is still in an encrypted state, such that the content is not adequately reproducible, that is, the content is not validated.
For example, if malfunctions occur on the network as the ID (identification) and the password are being transmitted from the server device to the client device, there arises a situation in which, even though the user has made payment, the user cannot validate the content.

first embodiment

[0105] A first embodiment of the present invention is now explained.

[0106] The network system embodying the present invention is configured as shown in FIG. 3. In the network system, shown in FIG. 3, an application server 100, a content server 310, a billing server 320, an accessing server 330 and a terminal device 400 are connected to the Internet 21. To a public network 22, a portable telephone set 200, the billing server 320 and the accessing server 330 are connected over a base station 23.

[0107] The base station 23 transmits / receives speech or data, over a radio route, with the portable telephone set 200 and with other portable telephone sets within a preset area, not shown.

[0108] The application server 100 performs the process of validating payable content provided from the content server 310 to the general public, such as music data, picture data or application programs for computers, in cooperation with portable telephone sets 200 or terminal devices 400.

[0109] The portab...

second embodiment

[0266] A second embodiment of the present invention will now be explained. In the second embodiment, when the process of content validation in the portable telephone set 200 or in the terminal device 400 has come to a close, the TID associated with the process is deleted from the application server 100. This enables the hardware resources (such as the HDD storage area) of the application server 100 to be utilized effectively.

[0267]FIG. 21 is a sequence diagram of a transaction to validate the content in the second embodiment of the present invention. FIG. 21 shows an example of content validation using the portable telephone set 200. In FIG. 21, processes similar to the processes shown in FIG. 16 are depicted by the same step numbers and the corresponding explanations are omitted for simplicity. Moreover, the processing by the content server 310 and the billing server 320 is the same as the processing of the first embodiment and hence the content server 310 and the billing server 3...

third embodiment

[0270] A third embodiment of the present invention will now be explained. In the third embodiment of the present invention, there is provided a defensive function against a person with a malignant intention. That is, even if data or messages transmitted on the network are intercepted, the content cannot be validated except by a device used by a person who paid for the content.

[0271]FIG. 22 shows a block diagram illustrating the processing functions of an application server in the third embodiment of the present invention. In FIG. 22, parts or components having the same functions as those of the first embodiment are depicted by the same reference numerals as those used in the first embodiment shown in FIG. 11, and the corresponding description is omitted for simplicity.

[0272] An application server 100a of the third embodiment corresponds to the application server 100 of the first embodiment shown in FIG. 11 except that it includes an encryption unit 116. Additionally, the function ...

Abstract

A communication system for guaranteeing only one each of two processing operations, correlated with each other and executed on different devices. A server has a unit which, on receipt of a first processing request, with identification information, executes this processing only once for one item of the identification, and a unit for transmitting a first processing completion notice to the transmission source of the processing request on completion of the first processing or on re-receipt of the processing request for the first processing with the same identification of the completed first processing. The client has a server, a unit for transmitting the processing request for first processing with identification information, a unit for executing a second processing, previously correlated with the first processing, on receipt of the completion notice, and a unit for re-transmitting a processing request on detection of an error before receipt of a transmitted completion notice.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a divisional of U.S. application Ser. No. 10 / 363,379, filed on Feb. 27, 2003, which is a U.S. national stage application of International Application No. PCT / JP02 / 06700, filed on Jul. 2, 2002, which has designated the U.S. and claims priority to Japan Patent Application No. 2001-204575 filed on Jul. 5, 2001, the disclosures of which are incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] This invention relates to a communication system for information communication between computers, a server device, a client device, a portable telephone set, a communication method, a concerted processing providing method, a concerted processing method, a billing surrogating method, a content validating method, a program and a recording medium. More particularly, it relates to a communication system for performing concerted processing among plural devices, interconnected over a network, a server device, a client devic...
