You can also save power by configuring automatic conversion.

The storage unit 23 stores the body information of each of the at least one service item 20 and information received from another wireless device for each service item.

Service items can be divided according to the nature of information to exchange with other users, for example, a commerce service, a meeting service, an emergency notification service. In addition, the body information means any information that a user intends to convey to other users in relation to each service item regardless of the unique meaning of the term.

Therefore, the body information for each service item may have different contents.

For example, the body information about a commerce service item may be made as information about a specific product (shape, color, material, place of purchase, price, etc.), such as a tie worn by the user, and the body information on a meeting service item may be Information and suggest a meeting (face image, photo, education, key, job, time and place you want to meet), and the text information on the emergency notification service item is information to inform the emergency ( Your name and address, your cell phone number, a message asking for help, your contacts, etc.).

The body information for each service item can be set arbitrarily by the user, but the type of service item must be shared by all wireless devices. Therefore, although the service items that the user wants to use can be selectively set in the wireless device among the service items prepared in advance, each user cannot create any service item by himself.

The service item set in each user's wireless device may be fixedly set at the time of manufacture or sale of the wireless device, and the service desired by the user on a server of a specific operator (for example, a server of a company planning and managing a service item). It can be set in various ways such as to download and set only items.

The information requesting unit 24 allows the user to select a desired service item among the currently set service items as shown in the example shown in FIG. 3, and when the user selects the service item and presses the transmit button, The information request signal is transmitted through the wireless transmitter / receiver 21 together with its identification information. When the wireless device 20 requests information of another wireless device, the wireless device 20 transmits an information request signal including information for designating a corresponding service item and its own identification information.

When the first reception processor 25 receives the response information transmitted from another wireless device through the wireless transmission / reception unit 21 according to the information request signal transmitted from the information request unit 24, the first reception processing unit 25 serves as response information for the corresponding service item. The storage unit 23 stores it. That is, in the area storing the received information of each service item in the storage unit 23, response information such as identification information and body information of another wireless device which has sent the response information is stored.

When the first transmission processor 26 receives an information request signal from another wireless device through the wireless transmission / reception unit 21, the first transmission processing unit 26 transmits the response information to the wireless transmission / reception unit 21. Here, the response information may include its own body information about the service item designated by the received information request signal, its own identification information, and identification information of another wireless device that has transmitted the information request signal.

The information management unit 27 has a service program 27-1 for setting and managing the body information for each service item, and displays various information stored in the storage unit 23 in the display unit 22-2.

In order to help the understanding of the description, the process performed between the wireless devices will be described with reference to FIG. 4.

If the user of the wireless device A 30 selects the service item 2 as shown in the example shown in FIG. 3, the wireless device A 30 transmits an information request signal for the service item 2 through the wireless transmission / reception unit 31. Then, the information request signal is received by the wireless device B 40 located around it.

The first transmission processor 46 of the wireless device B 40 accesses the body information for the service item 2 from the storage unit 43, and accesses the body information, the identification information of the wireless device B, and the identification information of the wireless device A. The response information including the transmission is transmitted through the wireless transmitter / receiver 41.

The wireless device A 30 receives the response information transmitted by the wireless device B 40 through the wireless transmission and reception unit 31, and transmits the response information of the other party to the information request signal through the identification information contained in the response information. Recognizing that it is a response, the first receiver 35 stores the identification information and the body information of the wireless device B included in the response information in the storage unit 33. In addition, the user A may query the response stored in the storage 33 through the information manager 37 immediately or after receiving the response information.

Of course, the wireless device B 40 may also store in the storage unit 43 that the information request signal from the wireless device A 30 has been received, and the user of the wireless device B 40 at any time who has information to himself or herself. You can inquire whether or not you have requested.

Meanwhile, referring to FIG. 5, when a wireless device A 51 transmits an information request signal, all the other wireless devices 52, 53, 54 are located within a radius of the wireless signal. 53, 54).

At this time, if the user of the wireless device A (51) wants to obtain information only from the wireless device B1 (52), the wireless device A (51) is the wireless device B1 (52), B2 (53), B3 (54) Since all the sent information can be received, the user of the wireless device A 51 can secure the information of the wireless device B1 52 that he or she wanted. However, the user of the radio device A 51 does not know who the user of the radio device B1 52 is, and furthermore, the identification information of the radio device B1 52 is more difficult to know, so that any one of the received information is radio device B1 52. It is difficult to determine whether it was received from

That is, when only information from a specific counterpart has an important meaning, it is necessary to make it easy to distinguish what information is sent from the wireless device B1 52 for convenience of use. Hereinafter, a wireless device possessed by the specific counterpart will be referred to as an 'target device'.

In addition, although the user of the radio devices B2 53 and B3 54 knows that there has been an information request signal from the radio device A 51, the radio device 53, 54 of the radio device A 51 of the radio device A 51 does not know. It is not known whether it was a target device.

Referring to FIG. 6, a wireless device that transmits an information request signal identifies and classifies response information from a target device among response information received from other wireless devices, and determines whether other wireless devices were the target device. A second embodiment for determining whether or not it will be described will be described. The second embodiment according to the present invention determines the target device through the reception time of the radio signal. Therefore, it is preferable that the user transmits the information request signal after bringing his wireless device as close to the target device as possible.

The second embodiment shown in FIG. 6 further includes a second receiving processor 68 and a second transmitting processor 69 as compared with the first embodiment shown in FIG. Other components 61 to 67 are the same as the corresponding components in the first embodiment described above.

When the response information is received from another wireless device, the second transmission processor 69 judges the first response information received as the response information sent from the wireless device (target device) to which the user has received the information, and receives the response information from the target device. One response information is processed separately from the response information received from another wireless device. For example, when the response information is stored in the storage unit 63, the main information field and the temporary information field are divided and stored so that the user manages the information stored in the storage unit 63 later. When you do it, it will make it easier to recognize.

In addition, the second transmission processing section 69 transmits the confirmation information to the other wireless device which has transmitted the response information. The identification information is information for enabling the other wireless device to confirm that it was the target device. The identification information includes identification information of all other wireless devices that have sent the response information and information on when the response information is received.

When the second receiving processor 68 receives the confirmation information transmitted by the other wireless device through the wireless transmitting / receiving unit 61, the second receiving processor 68 compares the reception time of the response information for each wireless device included in the received confirmation information, and responds to its own response. If the information receiving time is the fastest, it is determined that the user was the target device. If the device is the target device, information related to the wireless device that has transmitted the information request signal (for example, identification information of the wireless device, the time at which the information request signal was received, etc.) is classified as important information.

For better understanding of the description, a process of applying the second embodiment to the example illustrated in FIG. 5 will be described in more detail with reference to FIG. 7.

In response to the information request signal transmitted by the wireless device A, the wireless device A receives the response information transmitted from each of the other wireless devices B1, B2, and B3 (S71). In other words, the response information received from the target device is determined as the information desired by the device and distinguished from the response information of the other wireless device (S72). At this time, assuming that the response information from the wireless device B1 is received first, the wireless device B1 becomes the target device. In addition, the wireless device A transmits both the identification information and response information reception time of the wireless device B1, the identification information and response information reception time of the wireless device B2, and the identification information and response signal reception time of the wireless device B3 (S73).

The wireless devices B1, B2, and B3 all receive the information transmitted by the wireless device A in step S73, and perform the operations according to the processes of steps S74 to S76, respectively. Hereinafter, only the wireless device B1 will be described, but the same operations are performed in the wireless devices B2 and B3.

That is, the wireless device B1 compares its response information reception time with the response information reception time of other wireless devices B2 and B3 (S74), and determines whether its response information reception time is the fastest (S75). As a result of the determination, since the reception time of the response information of the wireless device B1 is the fastest, it is determined that the wireless device B was the target device of the wireless device A (S76). However, the other wireless devices B2 and B3 determine that their response information reception time is later than the response information reception time of the wireless device B1, so that they are not the target device for the wireless device A.

Referring to FIG. 8, a method of classifying and managing response information received from a target device or information transmitted by a counterpart wireless device using itself as a target device will be described with reference to the example described with reference to FIG. 7.

An embodiment of an information exchange method between wireless devices according to the present invention will now be described with reference to FIG. 12.

First, each wireless device (A, B1 ~ Bn) stores the body information for one or more service items to exchange information with the other party (S120-1, S120-2). The meaning of the service item and the body information is as described above.

When the user selects a desired service item from the wireless device A and instructs to request the other party's information by pressing the transmit button (S120-3), the wireless device A wirelessly transmits an information request signal requesting information on the corresponding service item (S120-3). S120-4). When transmitting the information request signal, the wireless device A's own identification information is also transmitted.

All other radio devices B1 to Bn, which are located within the reach of the radio signal from the radio device A and receive the information request signal of the radio device A, transmit response information including body information on the corresponding service item to the radio device A. (S120-5). The response information includes not only the body information of the corresponding service item, but also its own identification information and the identification information of the wireless device A.

Wireless device A determines the first received wireless device among the response information sent by other wireless devices B1 to Bn as the destination device (S120-6), and treats the response information of the destination device as the information requested by the device. Process differently from the information sent by other wireless devices (S120-7).

In this case, the classification processing is performed by distinguishing and processing response information received from the target device from response information received from other wireless devices, so that the user can easily grasp important information and temporary information. That is, the user may selectively query only the response information received from the target device, or may temporarily delete the temporary information.

In addition, the wireless device A transmits identification information and response information reception time (confirmation information) for all the other wireless devices B1 to Bn that have sent the response information (S120-8).

Then, the user A inquires and confirms various response information stored immediately or after receiving the response information (S120-9).

On the other hand, the other wireless device (B1 ~ Bn) receiving the confirmation information sent by the wireless device A compares its response information receiving time with the response information receiving time of the other wireless device (S120-10), and its response information The wireless device having the fastest reception time determines that the wireless device A is the target device of wireless device A (S120-11), and processes information related to wireless device A as important information (S120-12).

Here, the example of the division processing means that the information of the wireless device which has requested the information as its own target device can be classified and managed as more important information than the other information.

In addition, the users B1 to Bn inquire and confirm various information stored in their wireless devices (S120-13).

In this case, the service item set in each of the wireless devices A, B1 to Bn may include a service item related to commerce, and the body information corresponding to the service item may include information about a commerce target product. . In addition, the service item set in each of the wireless devices A, B1 to Bn may include a service item related to a meeting, and the body information corresponding to the service item may include information for introducing itself.

The information exchange method between the wireless devices according to the present invention is, of course, applicable to each embodiment that does not contrary to the nature of the above description of the information exchange wireless device according to the present invention.

In addition, the present invention is not limited to the above-described embodiments and can be variously modified by those skilled in the art without departing from the technical spirit of the present invention.

According to the present invention, it is possible to subdivide and set various types of information to be exchanged with other users for each service item, and easily exchange information desired by each other without direct contact between people. In addition, since it is possible to accurately determine who received what information when and who, it can be effectively applied to a variety of services that can be used such information, such as e-commerce, instant transactions, meetings, emergency notification services.
