[0004] 図 13の通信システムでは、携帯電話機に高価な GPSアンテナ、 GPS受信デバイス を必要とする。図 14は力かる高価な GPS受信デバイスを必要としない従来技術であ る (例えば特許文献 1参照)。この従来技術は、電柱などに路上掲示物 5を取り付け、 該掲示物にその地点の位置情報と地図情報サーバ 6のアドレスとをコードィ匕した QR コード (2次元コード) 5aを掲載しておく。携帯電話機 1の図示しない情報コード読取装 置 (カメラ、画像読取処理部）は、路上掲示物 5の QRコード 5aを読み取ってデコードし て位置情報とアドレスを取得し、該アドレスを用いて基地局 2、ネットワーク 3を介して 地図情報サーバ 6に接続し、位置情報を送信する。地図情報サーバ 6は該位置情報 が示す位置周辺の地図情報を読み出して前記と逆方向に携帯電話機 1に送信する また、雑誌、新聞、パンフレット、地図などの書籍上に記録されている QRコード (2次 元コード)を読み取って施設の位置情報を取得し、該施設を目的地とする従来技術 もある (特許文献 2、特許文献 3参照)。 In the communication system shown in FIG. 13, an expensive GPS antenna and GPS receiving device are required for the mobile phone. FIG. 14 shows a conventional technique that does not require a powerful and expensive GPS receiving device (see, for example, Patent Document 1). In this prior art, a road sign 5 is attached to a utility pole, and a QR code (two-dimensional code) 5a in which the position information of the point and the address of the map information server 6 are coded is posted on the sign.

Further, when a destination is input from the mobile phone terminal 20, it is possible to search for a guide route from the current position to the destination and download the guide route information to the mobile phone terminal 20. According to the communication system of FIG. 1, by using an RFID tag, a GPS receiving device is not required, and a medium corresponding to the current location is detected by detecting the current position of the mobile phone terminal without using a two-dimensional code. Information can be provided to the mobile phone terminal. In addition, in the RFID tag readable range (several centimeters to the maximum several meters), position information can be accurately read by simply holding the mobile phone terminal, for example, and usability can be improved. In addition, even in areas where GPS reception is not possible (for example, underground malls, indoor buildings, tunnels, etc.), there is an effect that it can be used within the mobile phone reception area.
[0011] (b) RFIDタグへの書込み法 [0011] (b) Writing to RFID tag
図 4は、 RFIDタグへの第 1の書込み方法説明図であり、 RFIDタグ設置管理者が RFIDタグを電柱、掲示板、施設などに設置する前に、該 RFIDタグに設置場所毎に異 なる位置情報を書き込んで事前に準備する場合である。  Fig. 4 is an explanatory diagram of the first writing method to the RFID tag. Before the RFID tag installation manager installs the RFID tag on a utility pole, bulletin board, facility, etc., the RFID tag has different positions for each installation location. This is a case where information is written and prepared in advance.
RFIDタグ 10a, 10b, . . .、 10Nは、 RFIDリーダ 21または RFID書込み装置 60 (RFIDラ イタ）力も電力、クロックを搬送波で供給されるパッシブ型であり、図では RFIDライタ 60 を複数示しているが説明のためであり、実際には 1台の RFIDライタ 60により各 RFIDタ グ 10a〜10Nに設置場所毎に異なる位置情報を書き込むようになつている。  RFID tag 10a, 10b,..., 10N is a passive type in which RFID reader 21 or RFID writer 60 (RFID writer) power is also supplied by power and clock with carrier wave, and the figure shows multiple RFID writer 60 However, this is for the purpose of explanation. Actually, a single RFID writer 60 writes different position information to each RFID tag 10a to 10N for each installation location.
RFIDタグ設置管理者は、タグ書き込み作業所 TWWにお 、て RFIDライタ 60を用い て各 RFIDタグ 10a, 10b, . . .、 10Nへ異なる位置情報をライトアトワンス（一度のみの 書込み)で書込みする。図 4の例では、 RFIDライタ 60の書き込み制御部 61の制御で 記憶部 62に設定してある座標 Aから座標 Nまでの座標情報を各 RFIDタグ 10a, 10b, . . .、 10Nに順次ライトアトワンスで書き込む。書込み制御部 61は詳細に示してないが 、 RFIDリーダ 21と同様な構成を備えている。この方法によれば、 RFIDタグ設置前に多 数の位置情報書込み済みの RFIDタグを簡単に準備可能になる。  The RFID tag installation manager writes different location information to each RFID tag 10a, 10b,..., 10N using the RFID writer 60 on the tag writing work site TWW with write-at-once (one-time writing). To do. In the example of FIG. 4, coordinate information from coordinates A to coordinates N set in the storage unit 62 under the control of the write control unit 61 of the RFID writer 60 is sequentially written to each RFID tag 10a, 10b,. Write at once. Although not shown in detail, the writing control unit 61 has a configuration similar to that of the RFID reader 21. According to this method, it is possible to easily prepare a large number of RFID tags in which position information has been written before the RFID tag is installed.
[0012] 図 5は RFID書込み制御フローである。予め、 RFIDライタ 60の記憶部 62に RFIDタグ 10a〜10Nに書き込むデータ (座標 A〜N)を設定記憶しておく（ステップ 101)。ついで 、パッシブ型の各 RFIDタグ 10a, 10b, . . .、 10Nにライトアトワンスで順次座標 A〜Nを 書込み (ステップ 102〜103)、書き込んだ RFIDタグをそれぞれの設置場所に設置す る（ステップ 104)。 FIG. 5 is an RFID write control flow. Data (coordinates A to N) to be written to the RFID tags 10a to 10N are set and stored in advance in the storage unit 62 of the RFID writer 60 (step 101). Next, write the coordinates A to N sequentially to each passive RFID tag 10a, 10b,..., 10N with write-at-once (steps 102 to 103), and install the written RFID tags at the respective installation locations ( Step 104).
各 RFIDタグ 10a, 10b, . . .、 10Nにライトアトワンスで位置情報を書き込むステップ 102において、 RFIDライタ 60は RFIDタグ 10a〜10Nからライトワンスフラグを読出し、該 ライトワンスフラグがオン（1回書込み済みである）かチェックし (ステップ 102a)、フラグ がオンでなければ位置情報を RFIDタグに書き込み (ステップ 102b)、 RFIDタグのライト ワンスフラグ（初期値はオフ）をオンにする（ステップ 102c)。一方、ステップ 102aにお いて、フラグがオンであれば、対象 RFIDタグは既に位置情報を書込み済みであるか ら再書き込みを禁止する (ステップ 102d)。 Step to write location information to each RFID tag 10a, 10b,. In 102, the RFID writer 60 reads the write-once flag from the RFID tags 10a to 10N and checks whether the write-once flag is on (already written once) (step 102a). Write to the RFID tag (step 102b), and turn on the write once flag (initial value is off) of the RFID tag (step 102c). On the other hand, if the flag is turned on in step 102a, the target RFID tag prohibits rewriting since the position information has already been written (step 102d).
以上より、 RFIDタグ設置管理者は RFIDタグ設置前に、設置場所毎に異なる位置情 報を RFIDタグに書込む簡単な作業で、位置情報書き込み済みの RFIDタグを多数準 備でき、作業コストメリットを格段に有利にできる。また、書き込み制御部 61は、 RFIDタ グに既に位置座標が書き込み済みであれば、位置座標の再書き込みを禁止するよう にしたから、 RFIDタグの設置後に、いたずらされて記録内容が改竄されるのを防止す ることがでさる。  From the above, RFID tag installation managers can prepare a large number of RFID tags with location information written in a simple task of writing different location information to the RFID tag before installing the RFID tag. Can be greatly advantageous. In addition, if the position coordinates have already been written to the RFID tag, the writing control unit 61 prohibits rewriting of the position coordinates. Therefore, after the RFID tag is installed, the recorded content is tampered with and the recorded contents are altered. It is possible to prevent this.
図 6は RFIDタグへの第 2の書込み方法説明図であり、 RFIDタグ設置管理者が RFID タグを電柱、掲示板、施設などに設置した後に、該 RFIDタグに設置場所の位置情報 を書き込む場合である。  Fig. 6 is an explanatory diagram of the second writing method to the RFID tag. When the RFID tag installation manager installs the RFID tag on a utility pole, bulletin board, facility, etc., the location information of the installation location is written to the RFID tag. is there.
RFIDライタ 60は、 GPSアンテナ 63および GPS受信デバイス 64を備え、 GPSにより自分 の現在位置 (経緯度）を測定できるようになって!/、る。処理部 65は操作部 66力 書込 み指示があると GPS受信デバイス 64が測定した位置座標を書き込み制御部 61に渡し 、書き込み制御部 61は入力された位置情報を電柱などに設置済みの RFIDタグ 10aに ライトアトワンスで書き込む。  The RFID writer 60 has a GPS antenna 63 and a GPS receiving device 64, and can measure its current position (latitude and longitude) by GPS! When there is a writing instruction, the processing unit 65 passes the position coordinates measured by the GPS receiving device 64 to the writing control unit 61, and the writing control unit 61 sends the input position information to the RFID already installed on the power pole etc. Write to Tag 10a with Write At Once.
図 7は RFID書込み制御フローである。 GPS受信機能を備えた RFIDライタ 60を持参し てパッシブ型の RFIDタグが既に設置された地点に赴き (ステップ 201)、該地点の位 置座標 (経緯度）を GPS機能により取得し (ステップ 202)、 RFIDタグ 10にライトアトワン スで位置座標を書込み (ステップ 203)、以後、全 RFIDタグに位置情報を書き込むま で上記処理を繰り返し (ステップ 204)、全 RFIDタグへの書き込み完了により処理を終 了する。  Figure 7 shows the RFID write control flow. Bring the RFID writer 60 equipped with a GPS reception function and go to a point where a passive RFID tag has already been installed (step 201), and obtain the position coordinates (latitude and longitude) of the point using the GPS function (step 202). ), Write the position coordinates to the RFID tag 10 with write-at-once (step 203), and then repeat the above process until the position information is written to all RFID tags (step 204). Exit.
各 RFIDタグにライトアトワンスで位置情報を書き込むステップ 203にお!/、て、 RFIDタ ダカ ライトワンスフラグを読出し、該ライトワンスフラグがオン（1回書込み済みである )かチェックし (ステップ 203a)、フラグがオンでなければ位置情報を RFIDタグに書き込 み（ステップ 203b)、 RFIDタグのライトワンスフラグをオンにする（ステップ 203c)。一方 、ステップ 203aにおいて、フラグがオンであれば、対象 RFIDタグは既に位置情報を書 込み済みであるから再書き込みを禁止する (ステップ 203d)。 Write the location information to each RFID tag with write-at-once Step 203! /, Read the RFID tag write-once flag and turn the write-once flag on (already written once) (Step 203a), if the flag is not on, the position information is written to the RFID tag (step 203b), and the write-once flag of the RFID tag is turned on (step 203c). On the other hand, if the flag is turned on in step 203a, the target RFID tag has already written the position information and prohibits rewriting (step 203d).
以上より、 RFIDタグ設置管理者は RFIDタグの設置場所にお 、て GPS受信部で取得 した位置情報 (座標）を、該 RFIDタグへ書込めばよぐ間違った位置情報を RFIDタグ に書き込むミスをなくせ、確実に正 、位置情報を RFIDタグに書き込むことができる。 また、書き込み制御部は RFIDタグに既に位置座標が書き込み済みであれば、位置 座標の再書き込みを禁止するようにしたから、 RFIDタグの設置後に、いたずらされて 記録内容が改竄されるのを防止することができる。  Based on the above, the RFID tag installation manager has made mistakes to write incorrect location information to the RFID tag by writing the location information (coordinates) acquired by the GPS receiver at the RFID tag installation location. The position information can be reliably written to the RFID tag. In addition, if the position coordinates have already been written to the RFID tag, the writing control unit prohibits rewriting of the position coordinates, so that it is prevented from being tampered with and tampering with the recorded contents after the RFID tag is installed. can do.
(c)サービスセンター力 メディア情報を受信する処理  (c) Service center processing process to receive media information
図 8は携帯電話端末 20 (図 1)が RFIDタグ 10から位置情報を取得し、該位置情報を 用いてサービスセンター 50からメディア情報を受信するまでの第 1の処理フローで、 RFIDタグ 10に位置情報として経緯度が記憶されている場合である。  FIG. 8 shows a first processing flow from the mobile phone terminal 20 (FIG. 1) acquiring location information from the RFID tag 10 to receiving media information from the service center 50 using the location information. This is a case where longitude and latitude are stored as position information.
地点 Aの電柱 81に固定設置された RFIDタグ 10に携帯電話端末 20を近づけると共に 、キー部 23で読取を指示する (ステップ 301)。読取指示により RFIDタグリーダ 21は RFIDタグ 10より位置情報 (経緯度）を読取ってアプリケーション処理部 22に入力する（ ステップ 302)。なお、 RFIDタグリーダ 21は RFIDタグ 10より位置情報を常時読み取って アプリケーション処理部 22に入力し、アプリケーション処理部 22はキー部 23より指示さ れたときのみ該位置情報を取り込んで以降の処理を行うようにもできる。  The mobile phone terminal 20 is brought close to the RFID tag 10 fixedly installed on the telephone pole 81 at the point A, and reading is instructed by the key unit 23 (step 301). In response to the reading instruction, the RFID tag reader 21 reads position information (latitude and longitude) from the RFID tag 10 and inputs it to the application processing unit 22 (step 302). The RFID tag reader 21 always reads the position information from the RFID tag 10 and inputs it to the application processing unit 22, and the application processing unit 22 captures the position information only when instructed by the key unit 23 and performs the subsequent processing.

The communication control unit 24 makes a dial-up connection to an Internet service provider (ISP) (not shown) via the radio base station 30 and the network 40, and passes a request message to the ISP. As a result, the ISP uses the home page address to connect to the information providing Sano 50a of the service center 50, and Position information (latitude and longitude) 71a, identifier 71b, time information 71c, and other additional information 71e are transmitted to the information providing server 50a of the service center (step 305).
情報提供サーノ ¾0aは要求メッセージを受信すれば、識別子 71bにより受信した経 緯度座標が RFIDタグ力も読取ったものであると判断し、データベース 50bより該経緯 度に応じた周辺地図などの画像情報あるいは文字情報あるいは音声情報を読み出 して前記の上り方向  When the information providing Sano ¾0a receives the request message, it determines that the latitude and longitude coordinates received by the identifier 71b are also read from the RFID tag power, and from the database 50b image information such as a surrounding map or characters according to the latitude and longitude.

The application processing unit 22 of the mobile phone 20 displays the received image or character on the monitor, or outputs the sound with a force (step 307).
以上のように、位置情報が RFIDタグ力も読取った情報であることを定義するデータ を、該位置情報に付加して前記サービスセンターに送信するようにしたから、サービ スセンターは送られてきた位置情報が携帯電話端末の現在位置であると判別し、該 現在位置に応じたメディア情報を正しく携帯電話端末に提供することができる。  As described above, since the data defining that the position information is information obtained by reading the RFID tag force is added to the position information and transmitted to the service center, the service center transmits the position information sent to the service center. It is possible to determine that the information is the current position of the mobile phone terminal, and to correctly provide the media information corresponding to the current position to the mobile phone terminal.
