RFID provides a sensing function that recognizes the surrounding environment and data (ID), which is a standard of judgment, to a host system (data center or database) through an RFID reader and a network, and the host system recognizes and judges the proper Provide service.

RFID is classified into an active type that requires power depending on the presence or absence of a power supply, and a passive type that is operated by an electromagnetic field of an RFID reader without supplying power directly from inside or outside. It has the advantage of reducing the required power and reducing the recognition distance from the RFID reader, but it is limited in operating time because it requires a power supply, and it is more expensive than the passive type, while the passive type is much lighter than the active type, Although it is cheap and can be used semi-permanently, it has a disadvantage of short recognition distance and relatively high power consumption in RFID reader.

The RFID terminal is a term for integrating and referring to an RFID reader, which is a device capable of acquiring information stored in an RFID, through a short-range sensor network, and an RFID writer that can store / change desired information in the RFID.

Acquisition by communication method.

The RFID 110 is attached to a predetermined object or person. The RFID 110 is an electronic system that stores RFID data and is generally called a transponder or an RFID tag. This specification refers to this as 'RFID'. The RFID 110 includes a small antenna so that data can be exchanged with the fusion terminal 200 wirelessly. In addition, the RFID 110 may include an integrated circuit (IC) chip capable of reading and writing RFID data. The RFID 110 may be an active type requiring a direct power supply, or may be a passive type operated by an electromagnetic field of the fusion terminal 200. The RFID 110 transmits RFID data to the fusion terminal 200 in response to a data request of the fusion terminal 200.

The fusion terminal 200 also serves as a function of an ordinary mobile communication terminal and an RFID terminal. The fusion terminal 200 reads the RFID data recorded in the RFID 110, converts the RFID data into data suitable for transmission to the mobile communication network, and transmits the data to the mobile communication network. In transmitting the RFID data to the mobile communication network, the fusion terminal 200 may transmit the RFID data in the form of a message, or may transmit the RFID data to the mobile communication network through a call channel connected by connecting a call channel.

The fusion terminal 200 includes an RFID data processing module that receives radio waves of a predetermined frequency band from the RFID 110 and reads RFID data contained in the radio waves. The RFID data processing module may also play a role of transmitting the corresponding data to the RFID in order to record new data or update the recorded data in the RFID. The fusion terminal 200 also processes functions such as voice calls, wireless Internet services (i.e., transmission and reception of wireless data), messages transmission and reception, similarly to ordinary mobile communication terminals.

Therefore, the fusion terminal 200 transmits the RFID data to the base station 150 of the mobile communication network. The mobile communication network base station 150 exchanges data with the fusion terminal 200 through wireless communication of a predefined protocol. The mobile communication network base station 150 transmits the RFID data received from the fusion terminal 200 to the information management server 170 through the data network 160.

The information management server 170 receives RFID data from the mobile communication network base station 150. In addition to the RFID data, it is preferable to send the information of the terminal 200 together with the information management server 170. The information management server 170 obtains the address information of the subscriber server 190 corresponding to the information of the fusion terminal 200 and transmits the RFID data to the subscriber server 190 corresponding to the obtained address information. At this time, the information management server may be connected to the subscriber server 190 via the Internet (180).

As shown in FIG. 1, when a terminal (120 of FIG. 1) that acquires RFID data and a terminal (1400 of FIG. 1) that are connected to the mobile communication network to transmit the corresponding data exist, the user transmits the RFID data to the mobile communication network. If you want to transmit by using it, there is not only the inconvenience of having to maintain and manage two terminals, but also need to repeat connection / release to the mobile communication network every time RFID data is transmitted. There is a problem that the occurrence of a transmission processing time delay and the occurrence of an error are high because it must be confirmed every time.

On the other hand, the present invention is continuously connected to the mobile communication network by making the terminal and the mobile communication terminal to acquire the RFID data into one convergence terminal 200, so that the RFID data can be acquired and transmitted using the mobile communication network without delay. The high throughput and low error rate can be guaranteed.

The codec unit 270 codes and decodes voice signals and data, but also functions to code RFID data as described above. Similarly, the mobile communication modem 220 not only performs modulation / demodulation of a voice signal for a voice call, but also modulates / demodulates RFID data. The mobile communication signal modulated by the mobile communication modem 220 is RF-processed by the RF unit 210 and transmitted to the mobile communication base station 150 through the mobile communication antenna 2810.

The RF unit 210 transmits and receives an RF signal through a mobile communication antenna 281 as a module for connecting a mobile communication network.

That is, the RFID data acquired from the RFID is transferred to the CPU through the RFID processing module (S530), and the corresponding data is sent to the mobile communication modem for transmission (S540). In response to the transfer request of the RFID data, the mobile communication modem accesses the mobile communication network and transmits the RFID data modulated into the mobile communication signal (S550). The RFID data is transmitted to the information management server through the mobile communication network and the data network (S560). At this time, the information of the fusion terminal is preferably transmitted to the information management server together with the RFID data.

The information management server determines whether the subscriber is a valid subscriber by using the fusion terminal information transmitted together with the RFID data (S561). If the terminal is a valid terminal, the information management server applies the billing application and security module to the information (S562), and transmits the RFID data to the subscriber server (S564). In this case, the call channel connection for the connection is maintained (S563). The result of the transmission is transmitted to the corresponding terminal using the connected call channel (S570).
