[32] Hereinafter, preferred embodiment of goods exchange service system and method according to the present invention is described referring to attached figures.

[33] FIG. 1 is a goods exchange system according to a preferred embodiment of the present invention.

[34] Referring to FIG. 1, the goods exchange system according to a preferred embodiment of the present invention comprises a web server 100, a matching operation server 102, a goods item database 104 and a user database 106.

[35] The web server generates 100 web pages necessary for goods exchange and provides the web pages to a user client 110. The web server 100 receives request information that user sends using interface of the web pages and processes the request information.

[36] The web server generates various web pages including a web page through which users can upload goods for goods exchange, a web page through which user can examine information on uploaded goods, and a web page through which user can search uploaded goods and provides generated web pages to the user client 110.

[37] The user client 110 performs communication with the web server 100 through network. The network may include various network including the Internet, a private network, a mobile network and WLAN, etc.

[38] Further, the user client 110 may be any kind of device that can perform communication through network and operate application such as web-browser including a PC, a notebook, PDA(Personal Digital Assistant) and a mobile terminal, etc.

[39] In, conventional web service for goods exchange, users upload goods item to exchange and web page for goods item is provided to users. In conventional web service, users can just check uploaded goods, it was hard to accomplish exchange substantially.

[40] In conventional goods exchange service, information on uploaded goods was provided to users in the form of web board. Therefore, users had to check each of the postings of web board one by one in order to search goods to exchange.

[41] Unlike electronic commerce where payment is performed with money, goods exchange can be accomplished when goods for exchange are matched. For example, when user A would like to exchange a TV for a video, the goods exchange can be accomplished when user A can find B who would like to exchange a video for a TV.

[42] However, it was hard to find user B who wants goods that user A uploaded and uploads goods that user A wants because goods information was provided in the form of web board. Although text search function was provided in goods exchange service, it took long time to find user matched using the text search.

[43] Further, in conventional goods exchange service, the exchange was generally accomplished by user's personal communication. When a user finds a matched user, the user accomplishes exchange through the communication with the matched user by mobile phone, e-mail, and electronic message, etc. Therefore, Automatic exchange by system could not be accomplished in convention goods exchange system. The exchange by user's personal communication caused many kinds of troubles such as overlapped exchange.

[44] In other words, the conventional goods exchange system just provided goods information and text search function, matching service for efficient goods exchange was not provided.

[45] According to a preferred embodiment of the present invention, the web server 100 provides web service by which goods exchange can be accomplished more efficiently

[46] The web server 100 according to a preferred embodiment of the present invention provides information on uploaded goods and text search function such as conventional system. Further, the 100 server provides matching operation information by which a uses can find other users to exchange goods with high probability

[47] The matching operation server analyzes information on uploaded goods for exchange and performs matching operation for the users that may exchange their goods with each other and provides the matching operation results to related users. For example, when user A would like to provide video other user and receive TV from other user, the matching operation server 102 finds a user who would like to TV to user and receive TV from other user. After finding matched users, the matching operation server 102 generates matching operation information.

[48] The detailed process for performing matching operation is described referring to other figures.

[49] Users can request matching operation to the web server 100 or the matching operation server 102, and the matching operation server 102 performs matching operation when matching operation is requested from the user client 110 or the web server 100.

[50] The matching operation server 102 may also perform matching operation at predetermined interval without regard to request from the user client 110 or the web server 100, and the match operation result is stored in the goods item database 104.

[51] The web server 100 provides web page including the matching operation result generated from the matching operation server 102 to the user client 110. Therefore, matched users can be found easily without text search.

[52] Further, the web server 100 completes goods exchange through exchange request and exchange acceptance. A user can obtain information on potential users with whom goods change can be accomplished and the user requests goods exchange to the potential users. The web server 100 provides an interface by which a user can send the exchange request to potential users obtained by matching operation or search. The interface may be in the form of a graphic button for requesting exchange. [53] When a user who received an exchange request accepts the exchange request, the exchange is accomplished. The web server provides an interface by which a user can accept the exchange request. According to a preferred embodiment of the present invention, if the exchange request is accepted, a flag indicating that exchange is accomplished is written in the goods item database 104 in order to prevent overlapped exchange.

[54] According to a preferred embodiment of the present invention, the web server 100 provides a personal web page by which user can examine the exchange request received from other users and other users with whom exchange can be accomplished.

[55] The personal web page is generated based on the information stored in the goods item database 104, information on exchange requests received from other users and information on whether exchange requests sent to other users are accepted is provided by the personal web page. The personal web page also provides matching operation result of the matching operation server 102 by which users can find other potential users with whom exchange can be accomplished.

[56] The goods item database 104 stores information on uploaded goods, exchange request information and accomplished exchange information. When event such as exchange request, exchange acceptance and goods upload occurs, the web server 100 generates a query for storing the event occurrence information and provides the query to the goods item database 104. The goods item database 104 stores the event occurrence information according to the provided query. A field structure of the goods item database 104 is described referring to another figure.

After variable grant is completed, matching operation using goods stored in the goods item database is performed. [96] In matching operation, information on the object goods and wish goods of each user in the goods item database is derived. A variable XMP is granted to a second user's wish goods and a variable YMP is granted to a second user's object goods. [97] If a goods in the goods item database is already exchanged between users, the matching operation for the goods is skipped . [98] In matching operation, it is determined if TMP(the wish goods of the first user) is identical to YMP(the object goods of the second user) in step 608. [99] If the TMP is not identical to YMP, matching operation for goods of other user is repeated. [100] If TMP is identical to YMP, it is determined if RMP(the object goods of the first user) is identical to the XMP(wish goods of the second user) in step 610. [101] If RMP is identical to XMP, matching between the first user and the second user is completed and a matching number is granted to the first user and the second user in step 612. [102] If RMP and XMP are not identical, TMP is changed into the wish goods of the second user, and matching operation process is performed again in step 614. After

TMP is changed into the wish goods of the second user, if the object goods of the third user is identical to the with goods of the second user and the wish goods of a third user is identical to the object goods of the first user, matching for the first user, second user and third user is completed. At this case, the first user, second user and third user exchange goods as shown in FIG. 5 [103] As described above, if the matching between the first user and the second user is not accomplished, matching for three users including the third user is performed.
