3 is a block diagram illustrating a schematic configuration of a mobile communication terminal 20 having a tag writer / reader function according to an embodiment of the present invention.

As shown in FIG. 3, the mobile communication terminal according to an exemplary embodiment establishes a connection between a tag writer 280 for recording unique identification information on a blank tag, and an RFID tag found by scanning nearby RFID tags. And a tag communication unit 250 for receiving information therefrom, a remote communication unit 270 for performing data communication with a host computer, information on a terminal, and unique information of an RFID tag identified by the tag communication unit. It includes a location information notification unit 211 transmitted to the host computer via.

The tag communication unit 250 performs two-way wireless communication with the RF tag in one embodiment. In order to establish a connection with an RFID tag in a single frequency band, the tag communication unit 250 is an RFID tag according to the present invention by using authentication information of a tag included in a signal received from the RFID tag. Authenticate Thereafter, communication identification information necessary for establishing a connection with a tag is assigned using unique information. The RFID tag can perform one-to-one communication with the terminal by transmitting and receiving data using the received communication identification information. Thereafter, the mobile communication terminal can establish communication with a plurality of RF tags that exist in the periphery individually. Since such communication technology is known a variety of protocols, a detailed description thereof will be omitted.

The remote communication unit 270 is a mobile communication protocol such as CDMA, GSM, WCDMA, WiBro, FH-OFDM, MC-SCDMA, TDD / TDMA, HMm, and Mobile Broadband Wireless Access (MBWA) in one embodiment. However, the present invention is not limited thereto, and the present invention is interpreted to cover various portable wireless communication technologies that can be connected to a host computer such as WLAN, ZigBee, and Bluetooth.

The position calculator 216 receives a position of at least one other mobile communication terminal with respect to the RFID tag and a distance between the RF tag from the host computer, and locates the terminal with a distance between the RFID tag and another mobile communication. The position of the RFID tag is calculated using the distance between the terminal location and the RFID tag. At this time, the position calculation method is shown in FIG. Here, the position calculation unit 216 may notify its host computer of its own information to receive its own position, or, if the GPS receiver is built in, calculates its own position.

Referring to FIG. 4, when the distance between the two or three mobile communication terminals and the RFID tag having the same unique number as each mobile communication terminal is drawn in a circle, an intersection point P is formed, and the intersection point of the RFID tag is shown. Location. Here, the number of mobile communication terminals to be used should be at least two, and the larger the number of mobile communication terminals, the more accurately the position of the RF tag can be obtained, but preferably three or more. However, if there is only one mobile communication terminal communicating with the found RFID tag, it may be able to determine the approximate location by notifying even the distance between the mobile terminal itself and the RFID tag. The method of obtaining the position of the RF tag may be triangulation technique or another method may be used.

Specifically, such a position calculation may be calculated by time synchronization from the terminal or the host computer with the distance information obtained from the three mobile communication terminals, the distance information obtained from the three mobile communication terminals at the terminal ( Each of the three terminals can be calculated by receiving them from the nearest terminal and sending them to the host computer).

In addition, when the location calculation is performed by using the tag terminal and the subscriber guardian terminal, the location information calculated by the tag terminal terminal can be used by a peer-to-peer (P2P) technology such as peer-to-peer. You can also send information directly to the terminal to mark the location immediately. That is, the three terminals may be two terminals including the server and the subscriber customer terminal, or the two terminals including the subscriber customer terminal may calculate and average the positions, respectively.

In one embodiment, the location information of the terminal notified by the location information notification unit 211 may be a unique number such as, for example, a phone number of the mobile communication terminal or its own location. The host computer may query the Home Location Registry of the mobile communication system that manages the location for each phone number from the received phone number to obtain location information of the corresponding terminal. Therefore, it is possible to grasp the location information for each tag module device.

According to a further aspect of the present invention, a mobile communication terminal according to a preferred embodiment further includes a location detecting unit 230 for determining the location of the terminal, wherein the information of the terminal notified by the location information notification unit 211 is the location. It may be a distance between the location information of the terminal identified by the grasping unit 230 and the RFID tag. For example, the positioning unit 230 may be a module that receives navigation data of a satellite calculating a position and processes data, such as a GPS module. Here, the position information is interpreted to include not only coordinate data but also basic data capable of calculating position coordinates, for example, navigation data.

In addition, the location determiner 230 may include a distance sensor to measure the distance to the RF tag. The specific distance measuring method may be performed by a general method using electromagnetic waves (RF), may use TDOA using the difference of arrival of sound as in terrestrial LBS, or may calculate distance using ultrasonic waves or sound waves.

In one embodiment, the location information notification unit 211 detects the nearby RFID tag periodically through the tag communication unit 250 or only at the request of the customer in order to minimize battery consumption. However, if there are numerous RFID tags in the vicinity of the mobile communication terminal, all of them are transmitted to the server through the tag communication unit 250 and the remote communication unit 270, so that the amount of data and the cost of heavy traffic may explode periodically or Upon request, the tag is scanned in the vicinity of the RFID tag and the tag registration unit 215 is searched to send information to the host computer 50 only when the corresponding RFID tag to be found exists. That is, the location information notifying unit 211 periodically wakes up to a power active state and scans nearby RFID tags to collect information.

As another example, the location information notification unit 211, when requested from the host computer 50 through the remote communication unit 270, detects nearby RFID tags and transmits unique information and distance information to the host computer 50. do. For example, when a user connects to the host computer 50 through his personal computer 30 and legally inquires about the location of a specific RFID tag, the host computer 50 is sent to all mobile communication terminals 20. Can be commanded to find an RF tag with that unique information. For example, such a command may be broadcast in a batch through a control channel of a mobile communication terminal. At this time, all the mobile communication terminals 20 are switched to the power active state and searches for the RFID tag having the corresponding unique information. The invention is intended in the claims to cover such embodiments.

According to an embodiment of the present invention, a mobile communication terminal transmits biometric information received through the tag communication unit 250 to a host computer through the remote communication unit 270 together with the unique information of the RFID tag. The biological information notification unit 213 is further included. As mentioned above, various health related data of a human or animal can be collected. These are combined with the RFID tag's unique information and sent to the host computer, so that the host computer may collect health-related data for the person or animal only at the time of transmission or in succession, or at the request of the customer (subscriber). .

According to an exemplary embodiment of the present invention, a mobile communication terminal includes an operation unit 290 for receiving an operation signal of a user, unique information of a tag received through the tag communication unit 215, and the operation unit 290. It may further include a tag registration unit 215 for registering the user of the tag by transmitting the personal information entered through the remote communication unit 270 through. The operation unit 290 may be, for example, a keypad, a touch screen, or voice recognition.

For example, an RFID tag provider might distribute an RFID tag that already has all the information recorded, as well as include nothing but a default or unique information on the tag. You can easily register using your own mobile terminal without visiting. The RFID tag user first visits a specific wireless Internet page, authenticates himself / herself according to a menu provided on this page, and inputs personal information through the operation unit 290. At this time, the personal information can be registered only by calling party number by simply accessing it. Accordingly, the RFID tag having the corresponding unique information may be matched with the user and may be databased. In addition, the corresponding unique information may be written to the memory by the tag writer. The tag writer 260 receives unique identification information to be stored in the memory 120 of the tag from the host computer or stores a plurality of unique information in its own memory. It transmits to a blank RF tag without identification information like a blank CD to give unique identification information. Such identification information may be stored in a mobile communication terminal or a host computer.

In the present embodiment, the position calculating unit 216, the position information notifying unit 211, the biometric information notifying unit 213, and the tag registering unit 215 are implemented by a microprocessor and a series of program codes executed by the same. One component of the control unit 210.
