      The present invention relates to a tag reader device and a tag reading method of a mobile terminal for providing a terminal user with information of a tag read by a reader in a mobile radio frequency identification (RFID) service, in particular, a mobile RFID service. The present invention relates to a tag reader device and a tag reading method of a mobile terminal for arranging a plurality of tag information read by a reader to provide to a terminal user.

RFID system attaches a small chip to various products to transmit tag information including various information related to the product, such as product description, price, manufacturer, etc. at a radio frequency, and receives tag information through a terminal equipped with a reader. Is a contactless recognition system that displays to the user. In such an RFID system, a mobile RFID service may read a tag by attaching a reader to a terminal, and may provide wireless Internet contents related to the information read by the tag to a wireless Internet terminal user including a mobile phone.

The mobile RFID system includes a reader chip in a mobile terminal provided with a mobile RFID service based on a mobile communication system environment, and the middleware of the mobile terminal is located in the middle of the reader chip and various application programs, thereby providing a desired function. Let it run smoothly. An example of middleware supporting such a mobile RFID service is a wireless Inernet Platform For Interoperability (“WIPI”) based platform. Mobile RFID service uses ISO / IEC 18000-6 Type B and ISO / IEC 18000-6 Type C tags, which are ISO / IEC standards.The memory structure of ISO / IEC 18000-6 Type C tags is shown in <Table 1>. same. Hereinafter, information read from each memory bank of a tag will be referred to as tag information.

Bank Bank name Usage 00 Reserved Save Password to Restrict Tag Access 01 UII RFID service code and class storage 10 TID Save unique identification number of tag 11 User Application service data storage

In Table 1, the UII (Unique Item Identifier) is an RFID service code that is uniquely assigned to each tag attached to each RFID service object. In the mobile RFID service, the UII uses an electronic product code (EPC) and a mobile code (m-Code). EPC is a world standard code created for logistics, and m-Code is a domestic code created for mobile RFID service. The mobile code is composed of a combination of a CC (Item Code), an ICC (Item Category Code), an IC (Item Code), and a SC (Serial Code) field. The mobile code can be used to distinguish a type of service target. In Table 1, a tag IDentifier (TID) is a unique identification number of a tag given when a tag is manufactured and is not related to an RFID service. Application data stored in the User Bank can be in various forms, and a plurality of application data can be stored according to the type of application service, and are stored in accordance with the format provided by the standard. The types of application data include application data expiration date, name, description, price, date of manufacture, expiration date, expiration date, manufacturer, contact number, contact number, e-mail, content adult grade, privacy grade, URL (Uniform Resource Locator), Classified into URN (Uniform Resource Name) and location information.

In general, the process of reading an RFID tag by a reader mounted on a mobile phone is as follows. ISO / IEC 18000-6 Type B and Type C have different tag reading process due to the characteristics of the tag. The following procedure assumes that the ISO / IEC 18000-6 Type C tag is read based on <Table 1>.

1. Access all tags in the reader's read range and read the mobile RFID service code of each tag.

2. Read tag application data by connecting each specific tag with each tag identifier individually.

3. Provide the tag information to the user to select the desired tag information.

When reading the mobile RFID service code in the above sequence, since the reader does not know the number of tags located within the read distance, the reader accesses an unspecified tag and reads the mobile RFID service code uniquely assigned to each tag. However, when reading the application data, since the distribution is already known, the application data is read by individually accessing the tag having a specific tag identifier.

1 is a block diagram showing a configuration of a tag information reader device 150 of a mobile terminal for using a conventional mobile RFID service.

In FIG. 1, the tag 100 is generally attached to a service object and has the memory information of Table 1, and the tag information stored in the memory of the tag 100 is transmitted to the terminal by the reader 111. Is sent. The tag reader device 150 of FIG. 1 includes an RFID unit 110, a controller 130, a display unit 131, and a memory 133. The RFID unit 110 is composed of a reader 111 and a tag information processor 115, the controller 130 controls the overall operation of the RFID unit 110, the tag information read through the RFID unit 110 Is stored in the memory 133, and the operation of the display unit 131 is controlled.

Referring to the RFID unit 110, the reader 111 reads tag information from a plurality of tags 100 at a read distance due to the antenna directionality of the reader 111. The tag information processor 115 transmits a tag read command to the reader 111 and stores tag information read through the reader 111 in the memory 133 under the control of the controller 130. In addition, when the tag reading operation is completed, the tag information stored in the memory 133 is read in cooperation with the controller 131 and the tag information processor 115 and the read tag information is displayed to the user through the display unit 131. The tag information processor 115 is included in a part of the operation of the middleware and the application when applied to the mobile terminal.

The display unit 131 may be formed of a liquid crystal display (LCD). The display unit 131 displays a transmission state or a state indicating various operation information provided from the controller 130 on the screen under the control of the controller 130. The memory 133 stores and provides tag data read through the RFID unit 110 as well as various data for processing and control of the controller 130.

The operation of the tag reader device of the mobile terminal using the conventional RFID service of FIG. 1 will be described briefly as follows.

1. The user of the mobile terminal starts reading the tag.

2. The tag information processor 115 commands the reader 111 to read the tag 100.

3. The reader 111 reads the tag information and delivers the tag information to the tag information processor 115, and the tag information processor 115 stores the tag information in the memory 133 until the reading of the tag 100 is completed. .

4. When the tag information processor 115 receives the tag reading end notification, the tag information processor 115 reads the tag information stored in the memory 133 in cooperation with the control unit 131 and displays the read tag information to the user through the display unit 131. Mark it. In the tag reader device and operation of the mobile terminal, since a plurality of tags exist in the read distance of the reader, a plurality of tag information finally provided to the user is also provided. In the standard document related to mobile RFID, there is no special standard for providing a plurality of tag information to a user. Therefore, when displaying a plurality of tag information read by a reader, the conventional mobile RFID application service simply displays the display without performing alignment in consideration of the user's selection. In the prior art, it may be considered to sort the tag information provided by the reader based on the read time. However, in the prior art, it is inappropriate to use the time as the sorting criterion for the following two reasons. First, the closest tag does not always respond first because the reader randomly determines how long each tag reacts to avoid collisions between tags. In addition, the same tag is read repeatedly several times to increase the response rate of the tag desired by the user. The tag information desired by the user may not be read in the first attempt.

Therefore, in the prior art, when a plurality of read tag information is displayed along with tag information that is not desired by the user, the user is inconvenient to find his or her desired tag information. In addition, when displaying a plurality of tag information, there is no predetermined sorting criterion, so a delay occurs when searching the tag information.

The present invention provides a tag reader device of a mobile terminal and a method of arranging tag information therefor that can enhance user convenience when providing tag information read by a reader to a terminal user in a mobile RFID service.

The present invention also provides a tag reader device of a mobile terminal and a method of arranging tag information for the mobile terminal to provide the terminal user with the tag information sorted according to a predetermined criterion when the reader reads a plurality of tag information in the mobile RFID service.

Terms to be described later are terms defined in consideration of functions in the present invention, and may be changed according to intentions or customs of users or operators. Therefore, the definition should be made based on the contents throughout the specification.

FIG. 2 is a block diagram illustrating a tag reader device 150 of a mobile terminal for using a mobile RFID service according to a first embodiment of the present invention. FIG. 2 is the same as the configuration shown in FIG. The same reference number will be used.

In FIG. 2, the tag 100 is generally attached to a product providing an RFID service, and tag information stored in a memory of the tag 100 is transmitted to the terminal by the reader 111 as shown in Table 1 above. . The tag reader device 250 of the present invention includes an RFID unit 210, a controller 230, a display unit 131, and a memory 133.

In the present invention, the RFID unit 210 includes a reader 111, a tag information processor 213, a counter 215, a tag information aligner 217, and the controller 230 controls the overall structure of the RFID unit 210. It controls the operation, stores the tag information read through the RFID unit 210 in the memory 133, and controls the operation of the display unit 131.

Referring to the RFID unit 210, the reader 111 reads tag information from a plurality of tags 100 at a read distance of the reader 111. Since the present invention proposes a method of arranging a plurality of tag information according to the following embodiment, it will be assumed herein that the reader 111 reads a plurality of tag information from a plurality of tags 100 within read distance. .

Meanwhile, depending on how the plurality of tags 100 are connected to one reader 111 or the position of the tag 100 according to the read distance of the reader 111, the reader does not read the plurality of tag information at once. Failure often occurs. In addition, when a user reads a specific tag 100 with a terminal equipped with a reader 111, the user generally directs the direction of the tag. Therefore, since the reader 111 reads all the tags 100 included in the read distance several times, the desired tag 100 is read more than other tags by the antenna direction of the reader and the distance from the tag 100. The tag information processor 213 stores the tag information read from the reader 111 in the memory 133, and determines whether the tag information stored in the memory 133 is duplicate tag information or not. The counter 215 is operated to count the number of times the tag information is duplicated. Hereinafter, a duplicate number of tag information counted through the counter 215 will be referred to as a duplicate counter. In the counter 215, the duplicated town counter is incremented by one each time the duplicated counter is overlapped, and the counted final number of duplicated counters is transmitted to the tag information processor 213 and stored in the memory 133. The tag information sorter 217 sorts the tag information in descending order based on a duplicate counter stored in the memory 133 in cooperation with the controller 230 and the tag information processor 213 when the tag reading operation is completed. The tag information processor 213 reads the tag information sorted in descending order and transmits the tag information to the controller 230. The controller 230 displays the sorted tag information to the user through the display unit 131, and the contents of the selected tag information. To the user.

The display unit 131 may be formed of a liquid crystal display (LCD). The display unit 131 displays a transmission state or a state indicating various operation information provided from the control unit 230 on the screen under the control of the control unit 230. In particular, the plurality of tag information read in the present embodiment displays the sort order counted by the duplicate counter so that the user can easily select the desired tag information. This is because the most frequently duplicated tag information is most likely to be tag information desired by the user. In other words, when a user reads a specific tag with a mobile terminal equipped with a reader, the direction of the tag is generally oriented, and since there is no obstacle between the tag and the reader, it is more likely to be read more frequently than other tags around it. The memory 133 stores and provides tag information read through the RFID unit 210 as well as various data for processing and controlling the duplicate counter information and the controller 230.

As described above, in the first embodiment of the present invention, the counter 215 and the user can quickly search the desired tag information among the information of the tag 100 read several times due to the read distance of the reader 111. The RFID unit 210 was designed by adding a tag information sorter 217.

Hereinafter, an operation of the tag reader device of the mobile terminal of FIG. 2 will be described with reference to FIG. 3.

3 is a flowchart illustrating a tag information sorting method of a mobile terminal for using a mobile RFID service according to a first embodiment of the present invention. Hereinafter, the method of FIG. 3 will be described with reference to FIG. 2.

FIG. 3 assumes that there are M tags 100 within the read distance of the reader 111 and that N tags are repeatedly read N times. The number of repetitions of a predetermined tag reading is called a read cycle, and it is assumed that the number of tags 100 read by the actual reader 111 in one tag reading operation is K.

In FIG. 3, when a user operates a tag reader device by operating a keypad (not shown) of the terminal, the tag information processor 213 transmits a tag read command to the reader 111 to start tag reading and the reader 111 in step 301. ) Read K tags 100 at a time. The tag read start starts at N = 0. In addition, as shown in step 301, the reader 111 uses a well-known tag collision prevention algorithm to prevent collision between tag information read when K tags are read at a time. In step 303, the read tag information is transferred to the tag information processor 213.

In step 305, the tag information processor 213 interoperates with the controller 230 to compare tag information previously stored in the memory 133 with tag information newly transmitted to the tag information processor 213 to determine whether there is duplicate tag information. To judge. If duplicate tag information exists in step 305, the flow proceeds to step 307 to increase the counter of the duplicated tag information by the counter 215. However, if duplicate tag information does not exist in step 305, the tag information processor 213 proceeds to step 309 and stores tag information that is not duplicated in the memory 133. On the other hand, after increasing the duplicate counter of the duplicated tag information in step 307, in step 311 the reader 111 checks whether the number of repetition of the tag read has reached a predetermined number of read cycles when the number of lead cycles does not reach In step 313, the number of tag read repetitions N is increased by 1, and then the process proceeds to step 301 again to repeat the tag read operation.

However, if the number of tag read repetitions N reaches the number of read cycles in step 311, the process proceeds to step 315. Therefore, the newly read tag information according to the steps 301 to 313 are stored in the memory 133 by the tag information processor 213 and the controller 230, and the duplicated tag information increases only the duplicate count and the memory 133. It is not stored in. To this end, the tag information read by the reader 111 in steps 305 and 307 is not immediately stored in the memory 133, and first, it is determined whether redundancy exists. Therefore, according to the present embodiment, since only non-overlapping tag information is stored in the memory 133, the memory capacity required for storing tag information can be reduced.

In step 315, the tag information sorter 217 sorts the plurality of tag information stored in the memory 133 in descending order based on the number of duplicate counts increased in step 307. The sorted tag information is displayed on the display unit 213 so that the terminal user can quickly search for desired tag information under the control of the tag information processor 213 and the controller 230 in step 317.

As described above, according to the first embodiment of the present invention, due to the directivity of the reader 111 and the distance between the tags, the user may quickly search for the desired tag among the information of the tag 100 read several times compared to other tags. The process of counting duplicate tag information and sorting tag information based on the number of duplicate counts was performed.

4 is a block diagram illustrating a configuration of a tag reader device 450 of a mobile terminal for using a mobile RFID service according to a second embodiment of the present invention. In FIG. 4, the same reference numerals are used for the same components as those of FIG. 2, and redundant descriptions of FIG. 2 will be omitted.

The tag reader device 450 of the present invention includes an RFID unit 410, a controller 430, a display unit 131, and a memory 133. The RFID unit 410 includes a reader 111, a tag information processor 413, and a tag information aligner 415. The controller 230 controls the overall operation of the RFID unit 410, and controls the RFID unit ( The tag information read through the 110 is stored in the memory 113, and the operation of the display unit 131 is controlled.

In the present embodiment, the reader 111 of the RFID unit 410 reads and transmits at least one tag 100 at a read distance to the tag information processor 413.

In this embodiment, the tag information processor 413 interlocks with the control unit 430 to check whether the alignment reference information for the tag information that is read several times in the direction of the antenna from the reader 111 is set in the memory 133. do. The alignment reference information for the tag information may use at least one of an RFID service code of a UII bank or application service data of a user bank in Table 1 above. Hereinafter, the RFID service code will be referred to as service code and application service data as application data.

In FIG. 4, the tag information sorter 415 determines whether the sorting reference information transmitted from the tag information processor 413 is a service code or application data. Here, the sorting reference information may be set by the user or may be selected by a user through a keypad not shown among a plurality of preset sorting reference information. The tag information sorter 415 sorts the plurality of tag information transmitted from the tag information processor 413 according to the sorting reference information.

The tag information processor 413 displays a plurality of tag information arranged in the tag information sorter 415 on the display unit 131 under the control of the controller 430 so that a user can easily select the tag information. Provides the user with the contents of the tag information selected by the user.

In the present invention, the display unit 131 displays the tag information arranged by the tag information sorter 315 so that the user can easily select the tag information. The memory 133 stores and provides tag information read through the reader 111, the sorting reference information, and various data for processing and control of the controller 430. As described above, according to the second embodiment of the present invention, among the tag 100 information read several times due to the read distance of the reader 111, the user can quickly search the desired tag information according to the setting of the sorting reference information. The tag information sorter 417 was added to design the RFID unit 410.

5A and 5B are flowcharts illustrating a method of aligning tag information of a mobile terminal for using a mobile RFID service according to a second embodiment of the present invention. First, when a user operates a tag reader device by operating a keypad, in step 501, the reader 111 reads tag information from a plurality of tags 100 within read distances, and the tag information processor 413 according to step 503. To pass. In operation 505, the tag information processor 413 receives tag information from the reader 111 and stores the tag information in the memory under the control of the controller 430.

According to an embodiment of the present disclosure, in step 507, the reader 111 performs a process of determining whether a repetition number of tag reads reaches a predetermined number of read cycles. When the number of read cycles is not reached in step 507, the reader 111 increases the number of tag read repetitions N by 1 in step 509 and then proceeds to step 501 again to repeat the tag read operation.

However, in step 507, the reader 111 proceeds to step 511 when the number of tag read repetitions N reaches the number of read cycles. In step 511, the tag information processor 413 checks whether the alignment reference information of the tag information is set in the memory 133. Here, the alignment reference information may use the application data or the service code described in Table 1. It is also possible to allow the user to define the sorting reference information. In step 513, the tag information processor 413 determines whether the alignment reference information checked in step 511 is application data of the tag information. In step 513, if the sorting reference information transmitted in step 511 is application data, the tag information sorter 415 proceeds to step 515 to sort tag information based on the application data. In operation 517, the tag information processor 413 displays and provides the sorted tag information on the display unit 131. The application data may include data validity period, name, description, price, date of manufacture, expiration date, expiration date, manufacturer, contact number, contact number, email address, adult content, privacy rating, and URL (as shown in Table 1). The data selected from Uniform Resource Locator (URN), Uniform Resource Name (URN), and location information may be used as alignment reference information, or two or more selected data may be combined and used as alignment reference information.

If the alignment reference information is not application data in step 513, the tag information processor 413 proceeds to step 519 and determines whether the alignment reference information checked in step 511 is a service code of tag information. If the sorting reference information is the service code in step 519, the tag information sorter 415 determines whether to sort the service code by group in step 525. As an example of sorting by group, the controller 430 indicates an item corresponding to a service code of tag information read from the reader 111 in the display unit 131, for example, an item such as a book, a record, a video, and the like. The user can set at least one service code to sort into groups.

Therefore, in step 525, when the tag information sorter 415 sorts tag information having different service codes into groups according to the service code, the tag information sorter 415 proceeds to step 527. Sort by and sort. If the tag information is not sorted by group in step 525, that is, only the tag information having the selected specific service code is sorted, the process proceeds to step 529, and the tag information sorter 415 selects in advance among the plurality of read tag information. Sort only tag information of specific service code. The tag information arranged in steps 527 and 529 is displayed on the display unit 131 through the tag information processor 413 in step 531 and provided to the terminal user.

On the other hand, if the alignment reference information is not a service code in step 519, the process proceeds to step 523 and processes as an error. The reason for performing the error processing in step 523 is that as described in FIG. 4, the sorting reference information for the tag information may be set as a service code or application data. Otherwise, the tag information processor 413 is stored in the memory 133. This is because it is determined that the sorting reference information is not set.

As described above, according to the second embodiment of the present invention, the tag information is sorted so that the tag information can be quickly inquired according to the preset sorting reference information.
