The operation according to the embodiment of the present invention configured as described above will be described in more detail with reference to FIGS. 3A to 3D.

First, in the present invention, a buyer or seller for purchasing or selling an item connects to an electronic commerce system using his communication terminal 200. Here, the communication terminal 200 uses a personal computer (PC) or a portable mobile communication terminal such as a mobile phone or a PDA capable of accessing the Internet. In addition, the communication network 300 mainly uses a public telephone network (PSTN) or the Internet network, the present invention will be described as an embodiment of the Internet network.

As shown in FIG. 3A, when the purchaser or seller terminal 200 is used to access the electronic commerce system 400 through the Internet, the electronic commerce system 400 may be connected to the terminal 200 connected to the Internet. The home page is displayed on the output unit 202 through the first connection unit 205, the first interface unit 204, and the processing unit 203.

After confirming this, the buyer or seller inputs his ID and a password if necessary through an input unit 201 such as a keypad provided in the terminal 200. (S102) (S302) When the ID and password are converted and processed by the processing unit 203 and transmitted to the corresponding electronic commerce system 400 through the first interface unit 204 and the first connection unit 205, the electronic commerce system 400 is provided with a first ID. 2 is transmitted to the operating system 405 through the connection unit 401, the second interface unit 403. The operating system 405 transmits the inputted ID and password to the e-commerce operation server 430 to log in.

The e-commerce operation server 430 checks the ID to determine the membership. (S202) (S204) If confirmed as a member, transmits and displays a screen for purchase or sale (S206).

If the purchaser selects a purchase registration using his terminal (S104), the electronic commerce system 400 confirms the selection (S208) and transmits the purchase information input screen to the purchaser terminal for display. (S210)

If the seller selects the sale registration using his terminal (S304), the electronic commerce system 400 checks the selling option (S208) and then displays the sales information input screen to the seller terminal. )

The buyer or seller who confirms the registration screen checks the screen and inputs purchase information or sales information. (S106) (S306).

After checking the inputted information in the electronic commerce system 400 (S212), whether the purchase request or the sales request is determined and proceeds with the corresponding process. (S214)

First, in the case of a purchase request by the purchaser, a purchase agent is generated (S216), and the purchase information is registered in the corresponding record and field set in the purchase database 412 (S218).

Here, the purchase information or sales information inputted by the buyer or seller and registered in the purchase database 412 or the sales database 413 may be purchased or sold agent program (hereinafter referred to as "purchasing agent" or Through the "Sales Agent", it is necessary to choose whether to buy or negotiate according to the automated rules, or whether the buyer or seller to buy or sell using the terminal directly. The selection criteria, deadlines for purchase and sales activities, and the negotiation rules for purchase and sales agents should be selected.

Here, the details of the purchase information are as follows.

Firstly, the item information includes a purchase item specification, an upper limit of purchase price, a lower limit of purchase price, and the like. The purchase negotiation mode needs to be selected whether to be set to automatic or manual negotiation mode for purchase, that is, negotiation mode (Auto, A) by the purchasing agent or manual negotiation mode (Manual, M) that the buyer negotiates directly. The negotiating partner selection criterion selects the minimum selling minimum among the sellers (Minimize Minimum) or the minimum selling average among the selling sellers (Minimize Average). The choice of counterpart allows the buyer to choose a counterparty to price negotiations. Others compare the upper and lower price ranges to reflect the choices such as limiting the search for those who have a smaller, larger, or higher sales limit.

Negotiation End Time (T1) enters the closing time for purchasing activities.

The purchasing agent rule selects and inputs the price suggestion collection and price suggestion activity model. The price suggestion activity model can lead to the termination of negotiations early by allowing the price suggestion to be proposed based on the number of times rather than the time in the activity model between user agents. Variables for determining the offer price include cases by time, number of proposals, time and number of proposals as shown in FIGS. 4A and 4B.

Meanwhile, specific contents of the sales information are as follows.

First, the product information includes the sales article specification, the upper limit of the sellable price, the lower limit of the sellable price, and the like. The sales negotiation mode should be selected whether to be in the auto or manual negotiation mode for sale, that is, the negotiation mode (Auto, A) by the sales agent or the manual negotiation mode (Manual, M) directly negotiated by the seller. The bargaining partner selection criterion selects the maximum buyer (Maximize Maximum) among the buyers or the maximum buyer (Maximize Average) among the buyers. Negotiation End Time (T2) enters the closing time for sales activities.

The purchasing agent rule selects and inputs the price suggestion collection and price suggestion activity model. The price suggestion activity model can lead to the termination of negotiations early by allowing the price suggestion to be proposed based on the number of times rather than the time in the activity model between user agents. Variables for determining the offer price include cases by time, number of proposals, time and number of proposals as shown in FIGS. 5A and 5B.

The sales database 413 is searched on the basis of the negotiation partner selection criteria input as described above to determine whether there is a corresponding counterpart (S220).

If the corresponding party is detected as a result of the search, the state of the purchase negotiation mode and the sale negotiation mode of the counterpart merchandise are checked. (S222) (S250).

If the negotiation partner is not found, if it is within the negotiation end time (T1), return to the sales information search step (S220) to re-search the sales database 413, and repeat this until the negotiation end time (S224).

If the registrant wanting the transaction is a merchandise seller, a sales agent is generated (S232), and the sales information input as described above is stored in the sales database 413. (S234)

The purchase information of the purchase database 412 is searched based on the selection criteria of the negotiation partner among the stored sales information. (S236) When the purchase negotiation partner is found, the states of the sales negotiation mode and the purchase negotiation mode are checked. (S238) (S250)

If the negotiation partner is not found, if it is within the negotiation end time (T2), it returns to the purchase information retrieval step (S236) to re-search the purchase database 412, and repeats this until the negotiation end time (T2). S240)

Negotiation type is either one of auto negotiation using buyer's agent (A) or manual negotiation by buyer directly (M) as shown in Table 1, and seller's auto negotiation (A) or seller using agent This mode is one of manual negotiation (M).

buyer seller One A A 2 A M 3 M A 4 M M

In this case, in the case of 2,3 (S251), the partner in the auto-negotiation (A) mode is directly inquired (M), and the negotiation relationship is switched from auto-negotiation (A) to direct negotiation (M). M, M) to go through the steps. Through this process, negotiation types are divided into three types: (A, A), (M, A), and (M, M). (S251) (S270) (S280)

For the other types of negotiations except (A, A), the type of desired price suggestion for each user is entered so that the number of price adjustments can be limited.

The negotiation process for each of the above negotiation types will be described in more detail as follows.

First, as illustrated in FIG. 3B, when the buyer is manual negotiation (M) and the seller is automatic negotiation (A) (S251), the manual negotiation (M) proposal data is transmitted to the seller terminal (S252).

If the seller terminal receives this (S311) and transmits the data accommodating the manual negotiation (M) (S312) (S313), the negotiation type is switched to the (M, M) mode to proceed with the negotiation.

Otherwise, the seller displays the intention of auto negotiation (A) (S314). After confirming the intention of auto negotiation (A) transmitted from the seller terminal, the process proceeds to the (M, A) negotiation mode. (S255)

3C is a flowchart illustrating a negotiation process of the (M, A) negotiation mode (S255), and first, the maximum price proposal collection request data is transmitted from the electronic commerce system 400 to the purchaser terminal 200. (S256) When the number of times is input in the terminal 200, the electronic commerce system 400 stores the maximum number of proposals N of the purchaser (S257).

Next, the purchaser terminal 200 requests a price suggestion (S258), and the sales agent receives a purchase offer price inputted by the buyer (S112) (S259).

If the sales agent fails to accept the proposed price (S260), the sales agent transmits the proposed price to the buyer terminal. (S261) If the buyer terminal receives and accepts the proposed price (S113), negotiation is concluded. If it is not accepted, the buyer returns to the price suggestion step (S112) and repeats the above process. (S114) At this time, the price suggestion repetition is performed within the set price suggestion number (N). )

In the above process, when it is accepted at the price suggested by the buyer or the e-commerce system 400, it is determined that the negotiation is concluded and the negotiation conclusion information is stored in the negotiation database 414. (S262) In addition, the negotiation result is stored with the buyer. Each of them is sent to the seller terminal to confirm. (S263) (S116) (S321).

FIG. 3D is a flowchart of a negotiation process when both the buyer and the seller are in the auto-negotiation mode (A, A) and in the case of the manual negotiation (M, M). As shown in the drawing, first, the (A, A) negotiation mode is shown. It will be described as follows.

First, when both the buyer and the seller are in the auto-negotiation mode (A, A) (S271), the auto-negotiation between the purchase agent and the sales agent (S272) is performed.

Negotiations between agents proceed according to the price suggestion activity model.

That is, as shown in FIGS. 4A, 4B and 5A, 5B, negotiations based on a price proposal are performed according to a purchase or sale price suggestion activity model set at the time of registering the purchase information or sale information (S272).

If the negotiation is not concluded, return to the sales information search step (S220) again within the purchase end time, and if the negotiation is concluded (S273), the negotiation conclusion information is stored in the negotiation database 414. (S273) (S274)

In addition, the result of the negotiation is transmitted through the buyer or seller terminal so that the buyer or the seller can check it (S275) (S122) (S336).

If both the buyer and seller negotiation mode are manual negotiations (M, M) (S280) (S281), the electronic commerce system 400 requests the buyer terminal and the seller terminal to input the maximum number of price proposals for manual negotiation respectively. (S282)

The number of times entered through the buyer terminal and the seller terminal stores the maximum number of proposals "N" (N = min (N1, N2)) (S283), and then requests the purchaser to enter a purchase price. )

When the buyer terminal inputs a proposed price to be purchased (S118), the buyer terminal mediates it and transmits it to the seller terminal (S285).

If the seller terminal receives and accepts the transmitted purchase offer price, the negotiation is concluded and stored in the negotiation database 414, and then the negotiation result is transmitted to each buyer and seller terminal (S274) (S275).

However, if the seller does not accept the received purchase offer price, after confirming whether or not within the maximum price proposal number (N) and transmits the price data that you want to sell through the seller terminal to the electronic commerce system 400. (S334 (S335)

In this case, when the maximum price suggestion number (N) is reached, it is returned to the sales information search step after checking whether it is within the end of the sales negotiation (S224).

The selling offer price transmitted from the seller terminal is mediated by the electronic commerce system 400 and transmitted to the buyer terminal. (S286) If the offer price received from the buyer terminal is accepted, the process proceeds to the negotiation conclusion stage and does not accept. If not, check whether it is within the maximum number of proposals and return to the buyer price suggestion step (S118).

If the maximum price suggestion is collected, it is returned to the purchase information search step after confirming whether it is within the end of the sales negotiation (S224).

Thus, the buyer and seller repeat the negotiation and search within the limited number of times and the negotiation end time until they accept the proposed price.

The buyer purchases the goods he wants as cheaply as possible or the seller sells the goods he wants to sell at his desired price.

Although the preferred embodiment according to the present invention has been described above, it is applicable not only to the Internet but also to PSTN, etc., and the buyer and seller are not only 1: 1, but various negotiations such as N: 1 or 1: N are possible, It will be understood by those skilled in the art that various modifications and variations can be made without departing from the scope of the claims.

As described above, the purchase and sale method according to the agent selection in the e-commerce according to the present invention can be negotiated by choosing the buyer directly participating or using the agent during the e-commerce transaction to expand the range of choice for the negotiation negotiation It has the effect of reflecting the preferences of buyers and sellers in the selection of trading partners, and the effect of the early closing of transactions due to the active participation of buyers and sellers, and the price determined by users in real time. By confirming the negotiation result, it is possible to increase the credibility of the transaction, which is effective in the transparency and activation of the transaction.
