ただし、距離は式１に限るものではない。ステップ８２２では現在地から最も近いアイコンが前回選択されたアイコンかどうか確認する。前回選択されたアイコンが最も近いアイコンである場合にはステップ８２１に移行する。異なる場合にはステップ８２３に移行する。ステップ８２３では上記現在地から最も近いアイコンを選択、ステップ８２４に移行する。ステップ８２４では選択されたアイコンの色を変更し、ステップ８２５に移行する。ステップ８２５では位置情報を示すアイコンを分割画面（例えば、左画面）上に表示し、ステップ８２６に移行する。ステップ８２６ではステップ８２３でアイコンが選択された詳細情報をメモリから読み出し、ステップ８２７に移行する。ステップ８２７ではステップ８２６でメモリから読み出された詳細情報を残る分割画面（右画面）に表示し、ステップ８２１に移行して、以下同様の動作を繰り返す。以上のようにアイコン自動選択が選択されている場合、常に現在地から最も近い地域サービス情報を自動的に表示することができる。
【００８８】
上述した例で説明すると、現在地が図２９のところにあるときは経路上でもっとも近いレストランＸＹＺの詳細情報を表示し、車１がレストランＸＹＺを通り過ぎ、現在地が図３０のところに来ると現時点で経路上もっとも近い喫茶○の詳細情報を表示する。このとき、通り過ぎたアイコンは表示しても非表示にしても構わない。また、アイコン表示する表示範囲の更新は車１の移動の度に行なってもよいし、一定時間あるいは一定距離間隔で行なってもよい。
【００８９】
上記では、情報サーバ５から位置情報と詳細情報とが同時に配信されるものとして説明したが、詳細情報が必ずしも位置情報と同時に配信される必要はない。詳細情報はアイコンを選択することにより情報サーバ５に要求され、配信されるよう構成してもよい。アイコンの自動選択を設定している場合にはステップ８２１の段階で、２番目に近い情報を常に先行して要求するように構成しておくことにより、位置情報と詳細情報を同時に受信するのと同じ効果がある。
【００９０】
実施の形態４の移動通信端末は、以上のように情報検索配信装置から配信された検索結果を位置情報と詳細情報に分け、位置情報をアイコン表示することにより現在地との位置関係を視覚的にわかりやすく表示し、詳細情報はアイコン選択することにより表示するよう構成されているため、利用者が欲しい情報を自身で選択して画面に表示することができる。また、移動通信端末の移動とともに最寄りの詳細情報を自動的に更新するように構成されているため、利用者は何もしなくても最寄りの詳細情報を得ることができる。
【００９１】
実施の形態５．
次に、本発明の実施の形態５を図３１を用いて説明する。図３１は実施の形態５のカーナビ３のブロック構成図であり、実施の形態４とは情報処理部２００の構成のみが異なる。実施の形態５の情報処理部２００は画像処理部１０３と情報検索範囲設定部２５からなる。
【００９２】
図３１を用いて、実施の形態５の移動通信端末の動作を具体的に説明する。補助記憶装置１０１より読み出された地図情報等の情報信号は一旦メモリ１０２に格納される。メモリ１０２では上記情報信号は、画像情報、番地情報とに区別される。地図情報等の画像情報は情報処理部２００に入力されるとともに、経路検索部１１２に入力される。また、番地情報は情報処理部２００に入力されるとともに、番地情報演算部１０６に入力される。一方、自車情報検知装置１０５により検知された現在地情報は番地情報演算部１０６に入力され、番地情報演算部１０６において自車の現在地と地図上の位置が照合される。番地情報演算部１０６より得られた自車位置情報は情報処理部２００に入力され、内部の画像処理部１０３でメモリ１０２より出力された地図情報と上記自車位置情報が加え合わされ、画像表示装置１０４に表示される。自車情報検知装置１０５において自車の現在地が不明の場合には、現在地設定部１１３において現在地を入力することにより上記番地情報演算部１０６と同様の動作を行なう。
【００９３】
目的地設定部１１１で目的地を設定した場合には目的地設定部１１１より目的地情報が経路検索部１１２に出力される。経路検索部１１２では目的地設定部１１１より出力される目的地情報、メモリ１０２より出力される地図情報、番地情報演算部１０６あるいは現在地設定部１１３より出力された現在地情報をもとに現在地から目的地までの経路検索を行なう。経路検索部１１２より出力される現在地、目的地、目的地経路情報は情報処理部２００に入力され、画像処理部１０３で画像変換されて画像表示装置１０４に表示される。
【００９４】
また、経路探索部１１２より出力された現在地、目的地、目的地経路は情報処理部２００内部の情報検索範囲設定部２５にも入力される。情報検索範囲設定部２５では上記情報に加えて、自車情報検知装置１０５で検知された自車の進行方向、移動速度から情報検索範囲を設定する。具体的な情報検索範囲設定の方法は実施の形態１と同様である。
【００９５】
上記情報検索範囲設定部２５で設定された情報検索範囲はメモリ１１５に格納される。通信部１１４では、検索項目設定部１１６により設定されメモリ１１５に格納された情報検索項目とともに上記情報検索範囲をメモリ１１５から読み出し、情報サーバ５に送信する。
【００９６】
カーナビ３から情報サーバ５に送信する情報検索範囲指定パケットの一例を図３２に示す。図３２はカーナビ３に目的地経路情報があり、その目的地経路情報に基づき情報検索範囲を設定した場合である。この場合、現在地、目的地、および検索中心地点（図１４、図１５参照）がそれぞれパケットとして送信される。また、それぞれのパケットはヘッダ、データ属性（現在地、目的地、検索中心地点等の区別をする）、総パケット数、残りパケット数、日時、緯度、経度、範囲パラメータ（検索中心地点に対する各情報検索範囲を指定する四角形の一辺、あるいは円の半径等）、フッタ等から構成される。また、進行速度情報や移動速度情報により情報検索範囲を決定したときには、データ属性で現在地を指定するとともに、円や扇形の半径、扇形の中心角（検索範囲を円形、扇形とした場合）を上記範囲パラメータとして送信する。なお、上記パケットは情報検索範囲設定部２５で生成する。
【００９７】
情報サーバ５では上記送信された情報検索範囲と情報検索項目から情報を検索し、カーナビ３に検索結果を送信する。
【００９８】
情報サーバ５より送信された地域サービス情報は通信部１１４により受信され、メモリ１１５に格納される。メモリ１１５では、上記地域サービス情報は位置情報と詳細情報とに分けられる。地域サービス情報の位置情報と詳細情報は情報処理部２００内部の画像処理部１０３で処理され、画像表示装置１０４に表示される。
【００９９】
実施の形態５の移動通信端末は、以上のように移動通信端末が有する現在地情報等の移動通信端末情報をもとに情報検索範囲を設定し、その情報検索範囲を情報検索項目とともに情報検索配信装置に送信し、情報検索配信装置において情報検索を行なうよう構成されているので、移動通信端末が移動先で必要とするその移動先周辺の情報を効率よく得ることができる。また、移動通信端末情報として進行方向情報を有する場合には上記情報検索範囲を進行方向側に広く設定し、移動速度情報を有する場合には上記情報検索範囲をその移動速度に応じて設定するので、移動通信端末の移動状態に応じた情報検索範囲の設定が行なえる。さらに、移動通信端末情報として移動通信端末がこの先移動する経路を表わす目的地経路情報を有している場合には、上記目的地経路に沿った情報検索範囲を設定し、その範囲内で情報検索を行なうので移動通信端末の移動に支障のない検索結果を配信することができる。
【０１００】
また、実施の形態５の移動通信端末は、移動通信端末が有する情報をもとに検索範囲を設定し情報サーバに通知することにより、可能な限り移動通信端末の移動する経路に沿った情報を得ることができる。インターネットなどを利用したキーワード検索の結果に比べて、より移動先の地域に限定された情報を効率よく得ることができる。また、利用者の方でキーワード検索による膨大な数の検索結果から本当に必要な情報、つまり、移動中に必要とする情報を選び出す手間が省ける。また、情報サーバに蓄積する情報を更新することにより移動通信端末は常に最新の情報を得ることができる効果がある。
【０１０１】
本実施の形態１から実施の形態３の移動通信端末向け情報検索配信装置、および実施の形態５の移動通信端末は、移動通信端末が有する情報を有効利用して情報検索方法と情報検索範囲を設定し、情報検索を行なうよう構成されているため、効率よく情報検索をすることができる。また、検索範囲を適宜絞り込むことにより探索時間を短縮することができるとともに、位置的に必要な情報のみを得ることができる。
【０１０２】
また、本実施の形態２の移動通信端末は、情報送信命令部３２において一定時間間隔でカーナビ３に情報送信要求を出すように構成したがこれに限るものではない。例えば、過去にカーナビ３から送信された移動速度情報とタイマー３１より出力される時間から移動距離を求める、あるいは、過去の現在地から推測される移動速度とタイマー３１より出力される時間から移動距離を求めることにより、一定距離ごとにカーナビ３に情報送信要求を出すように構成してもよい。
【０１０３】
また、本実施の形態４の移動通信端末は、情報検索配信装置より配信される検索結果を一旦アイコン化しモニタ画面の地図上に表示するよう構成されているため、視覚的に現在地との位置関係を容易に把握することができる。詳細情報の内容に応じてアイコンの形状、あるいは色等を変えて表示することにより、アイコンから内容がおよそ把握でき、必要であれば上記アイコンを選択することにより詳細情報を得ることができる。
【０１０４】
また、本実施の形態４の移動通信端末はその移動とともに経路上のもっとも近い詳細情報を自動で得ることができるため、走行中にアイコンを選択する必要がない。
【０１０５】
実施の形態１から実施の形態５では移動通信端末としてカーナビを用いたがこれに限るものではない。移動通信端末としてＰＤＡを用いても、ＨＰＣを用いても同様の効果を奏することは言うまでもない。
【０１０６】
また、移動通信端末の現在地を測定する手段としてＧＰＳを用いたがこれに限るものではない。発信機のように移動通信端末側では現在地を知る術がないものでも、基地局で上記移動通信端末の現在地が確認できる場合には同様の効果を奏することはいうまでもない。ＰＨＳ（パーソナルハンディフォンのことを指す）のように通信に際してＰＨＳの所在地がセル単位で分かるような場合にも同様の効果を奏することはいうまでもない。
【０１０７】
また、現在地が正確にわからない、つまり、緯度、経度、標高がわからない場合にも移動通信端末で現在地の住所、あるいは施設名を選択し基地局に通知するように構成しておけば、実施の形態１から実施の形態４、および実施の形態５の情報検索が行なえることは言うまでもない。
【０１０８】
また、本実施の形態４および実施の形態５ではカーナビ自体に通信機能を持たせたが、必ずしもカーナビに内蔵されている必要はない。カーナビと通信機をアダプタで接続し、カーナビから各種情報を通信機を通じて基地局に通知し、同様に検索結果は通信機を通じてカーナビに配信するよう構成してもよい。これは移動通信端末としてＰＤＡ、ＨＰＣ等を使用した場合にも同様である。
【０１０９】
また、本実施の形態１から実施の形態３で情報サーバ５が移動通信端末からの検索項目について検索する情報は上記情報サーバ５がローカルに蓄積している情報に限るものではなく、インターネット等を通じて電子的に接続された遠隔地のサーバに蓄積された情報であっても構わない。
【０１１０】
【発明の効果】
本発明は、以上説明したように構成されているので、以下に示すような効果を奏する。
【０１１１】
移動通信端末向け情報検索配信装置は、移動通信端末に対して、情報送信要求手段により現在地情報等の移動通信端末情報と情報検索項目の送信要求を行ない、上記送信要求に対して移動通信端末は移動通信端末情報と情報検索項目を情報検索配信装置に送信し、情報検索配信装置では上記情報検索範囲内で情報検索項目について地域サービス情報等の検索を行ない、検索結果は通信手段を用いて検索要求のあった上記移動通信端末に配信する。なお、一定距離ごとに情報検索配信装置は移動通信端末に情報送信要求をだす。よって、頻繁に情報検索を行なう場合などに、あらかじめ、情報検索項目を設定しておくことにより自動的に情報検索を行ない、その結果を得ることができる。
【０１１２】
さらに、移動通信端末向け情報検索配信装置は、移動通信端末から送信された現在地情報等の移動通信端末情報に基づき、情報検索範囲決定手段により情報検索範囲を設定し、また、情報検索項目決定手段により移動通信端末から過去に送信された移動通信端末情報と情報検索項目から情報検索項目を決定し、上記情報検索範囲内で上記情報検索項目について地域サービス情報等の検索を行ない、検索結果は通信手段を用いて移動通信端末に配信する。なお、情報検索項目決定手段では移動通信端末から過去に検索要求のあった時間帯と利用状況をユーザ履歴情報として蓄積し、上記ユーザ履歴情報に基づき情報検索項目を決定し、移動通信端末に検索結果を配信する。よって、移動通信端末から検索要求をしなくても定期的に必要な情報を得ることができる。
【０１１３】
また、移動通信端末は、移動通信端末情報設定測定手段により、現在地情報等の移動通信端末情報を設定あるいは測定し、情報検索範囲決定手段により上記移動通信端末情報設定測定手段から得られる移動通信端末情報から情報検索範囲を決定し、情報検索項目設定手段により地域サービス情報等の検索項目を設定して、上記移動通信端末情報と情報検索項目を携帯電話等の通信手段を用いて情報検索配信装置に通知し、地域サービス情報等の検索結果を受信。そして、受信した検索結果は表示手段により位置情報と詳細情報とに分けて表示する。なお、情報検索範囲決定手段により現在地情報等の移動通信端末情報から決定した情報検索範囲と情報検索項目を一定距離ごとに自動送信する。よって、移動通信端末は移動中、利用者が何ら操作することなく自動的に情報検索を行ない、移動先の情報を得ることができる。
【０１１４】
さらに、情報検索配信装置から検索結果を受信する移動通信端末において、移動通信端末は移動通信端末情報設定測定手段により現在地情報等の移動通信端末情報を設定あるいは測定し、情報検索項目設定手段により地域サービス情報等の検索項目を設定して、上記移動通信端末情報および情報検索項目を携帯電話等の通信手段を用いて情報検索配信装置に通知し、地域サービス情報等の検索結果を受信する。そして、受信した検索結果は表示手段により位置情報と詳細情報とに分けて表示する。なお、上記詳細情報表示が移動通信端末の移動とともに現在地に最も近い詳細情報に更新され、上記位置情報を上記表示手段上に表示された地図上にアイコン形式で表示する。よって、移動通信端末は利用者が手を煩わされることなく常に最も近い詳細情報を得ることができ、また、移動通信端末は位置情報をアイコンの形で表示するため、現在地に対する情報の所在地が視覚的に分かり易く、利用者自身が情報の所在地を知った上でアイコン選択することにより詳細情報を表示するので、利用者の意思によって必要な情報のみ取り出すことができる。

BACKGROUND OF THE INVENTION
The present invention relates to movement of a car navigation system (hereinafter referred to as a car navigation system), a personal data assistant (hereinafter referred to as a PDA), a handheld personal computer (a palm-sized portable personal computer; hereinafter referred to as an HPC), or the like. A mobile communication terminal that determines an information search range based on mobile communication terminal information such as current location information transmitted from a communication terminal, performs information search within the search range for search items, and distributes search results to the mobile communication terminal The present invention relates to a directed information search and distribution device and a mobile communication terminal.
[0002]
[Prior art]
Car navigation, which is one of mobile terminals, is a system that receives radio waves from a satellite and measures the current position. The amount of movement of a vehicle using GPS (Global Positioning System), a gyro sensor, and a vehicle speed sensor. The current position of the vehicle is measured by a self-contained navigation method that measures the distance to the destination while displaying it on the map recorded on the map disk. In addition, by designating a destination on the map in advance and creating a route (route) to the destination, it is possible to guide the route to the destination with a map screen and voice while traveling. (What is described as destination route information below is information indicating the route to this destination.) Furthermore, recently, traffic congestion information and accidents provided by a road traffic information communication system called “VICS”, Traffic-related information such as regulations and parking space availability can also be displayed on the screen in real time.
[0003]
FIG. 33 is a block diagram showing a conventional apparatus disclosed in, for example, Japanese Patent Publication No. 5-81907. In the figure, an information signal recorded on a CD-ROM is reproduced by a CD-ROM driver 301. This information signal is temporarily stored in a memory 302, and then distinguished into image information, address information, and address information. Among the signals, image information and number information are input to the image processing circuit 303. The image processing circuit 303 processes the two types of signals in a form suitable for an image display device 304 such as a TV, and then sends the processed signal to the image display device 304. On the other hand, the position information detected by the vehicle position detection device 305 and the address information are input to the address information calculation circuit 306, and the address information calculation circuit 306 collates the position of the vehicle with the position on the map. The vehicle position information is input to the image processing circuit 303 to be displayed on the image display device 304. In this image processing circuit 303, the image information and the vehicle position information are added and displayed on the image display device 304.
[0004]
Of the information signals stored in the memory 302, the address information is input to the address information extraction circuit 307. The coincidence information is input to the circuit 307 from the address information calculation circuit 306. The coincidence information is information indicating that the vehicle position calculated by the address information computation circuit 306 matches the address on the map where the address information exists, for example, the addresses indicated by P, Q, and R in FIG. . In response to this match information, the address information extraction circuit 307 sends the address information of the address to the search command circuit 308.
[0005]
Now, address information will be described. The map of the normal pattern shown in FIG. 34 is the map of address number 001, and the city area of W city is included in the map, and the address number of the enlarged pattern map (FIG. 35) representing this city area is 002. To do. In this case, all of the address numbers written at the points P, Q, and R in FIG. Now, the operation when driving from the S point to the T point will be described. Referring to the map of the normal pattern in FIG. 34, the coincidence information is sent from the address information calculation circuit 306 to the address information extraction circuit 307 when the vehicle position reaches the point P from the point S. The address number 002 is sent to the search command circuit 308. As a result, the search command circuit 308 operates to instruct the CD-ROM driver 301 to search the map of the enlarged pattern of the address number 002. As a result, the CD-ROM driver 301 searches the CD-ROM for an enlarged pattern map (FIG. 35) representing the W city area, and this map is displayed together with the vehicle position on the image display device 304 in the same manner as the normal pattern map. The driver can drive with reference to this city map. By the way, the places corresponding to P2, Q2, and R2 on the W city street map indicated by the address number 002 are the same points as P, Q, and R on the normal pattern map (FIG. 34) indicated by the address number 001. The address numbers of P2, Q2, and R2 are 001. Therefore, when the car reaches R2 from P2, the normal pattern map of the address number 001 is displayed by the same operation as described above. In this way, the driver can continue driving according to the normal pattern map shown in FIG. 34, and can safely reach the T point.
[0006]
As described above, since the two types of maps of the normal pattern and the enlarged pattern with different scale ratios are automatically switched according to the address number provided on each of the above maps, traffic regulation and detailed roads are required during city driving. It is possible to refer to a map with a small scale ratio written in the map, etc., a map with a large scale ratio while driving in the suburbs, and a map with an appropriate scale according to the driving situation. Convenient, safe and secure driving can be performed.
[0007]
[Problems to be solved by the invention]
As described above, the conventional car navigation system is a system that provides convenient, safe and reliable driving when the driver drives the car. However, the main purpose of the car navigation system is to guide the car to the destination. As a result, most of the information provided by the CD-ROM is map information, and information that is not related to direct driving such as regional service information. There are few offers. Even when such information is provided in the form of a CD-ROM, the latest information is not necessarily provided. On the other hand, in the case of recent car navigation systems, there is “VICS” that receives information related to road traffic such as traffic jam information, regulation information, parking lot information, etc. in a method called FM multiplex broadcasting, optical / radio wave beacon. In addition, the information provided is limited to road traffic information, and there is little information that the driver can use at the destination. In other words, in the current system, various information required by the mobile communication terminal including the current car navigation system before the movement (for example, if the vehicle is moving by car, parking space availability information, restaurant information, recommended sightseeing spot information, etc.) are not necessarily provided. It is not timely, hot and efficient. Specifically, even when the current location or the planned location of movement is known as in car navigation, the location information cannot be effectively used for information retrieval.
[0008]
The present invention has been made in order to solve the above-described problems. The mobile communication terminal determines an information search range based on mobile communication terminal information such as current location information of a mobile communication terminal as well as a car navigation system.

However, the own vehicle information that can be notified to the base station 2 by the car navigation 3 is limited to information that the car navigation 3 has at the time of communication, and depending on the configuration of the car 1, there is information that the car navigation 3 does not have. In addition, the car navigation 3 does not necessarily have to have a communication function, but a communication means such as a mobile phone is provided outside the car navigation, and the communication means notifies the base station 2 of the vehicle information that the car navigation 3 has. May be.
[0043]
The base station 2 has an information server 5. The information server 5 determines an information search range based on the own vehicle information notified from the car navigation 3 to the base station 2. Further, information search within the above information search range is performed for the search item, and the search result is distributed to the car navigation 3. The area where the information server 5 searches for information is not limited to the information stored locally in the information server 5 in the base station 2 notified from the car navigation 3, but is stored in a remote server connected through a network such as the Internet. Information may be provided.
[0044]

A processing unit 15 sets an information search range from the vehicle information and information search items, performs an information search item within the search range, and outputs a search result to the sending unit 13a, and 15 is a database in which regional service information is accumulated. The search is performed by the processing unit 14.
[0045]
FIG. 3 is a block diagram of the processing unit 14. 20 is an input terminal for the vehicle information and information search items output from the reception unit 12, 21 is an output terminal for outputting the search result to the sending unit 13a, 22 is a terminal for searching the database 15 for information, and 23 is a search from the database 15 A terminal for receiving the result, 24 is the vehicle information and information retrieval item input from the input terminal 20, a memory for temporarily storing the retrieval result output to the output terminal 21, and 25 is a vehicle for reading out the vehicle information from the memory 24 and setting an information retrieval range. An information search range setting unit 26 to be set is an information search unit that searches for information search items stored in the memory 24 within the information search range set by the information search range setting unit 25.
[0046]
The operation of the information server 5 according to the first embodiment will be described with reference to FIGS. The own vehicle information and information retrieval items transmitted from the car navigation 3 are input to the receiving unit 12 via the input terminal 10. The reception unit 12 converts the received vehicle information and information search items into a form that can be processed by the processing unit 14 and outputs the converted information to the processing unit 14. The vehicle information and information retrieval items input to the processing unit 14 via the input terminal 20 are temporarily stored in the memory 24. Of the information stored in the memory 24, the vehicle information is input to the information search range setting unit 25, and the information search unit 26 sets a search range for performing information search. The setting of the information search range in the information search range setting unit 25 will be described later.
[0047]
The search range set in the information search range setting unit 25 is output to the information search unit 26. The information search unit 26 searches the information search items stored in the memory 24 within the search range set by the information search range setting unit 25. The search is performed with the database 15 via the terminal 22. The search result is input from the database 15 to the information search unit 26 via the terminal 23 and then stored in the memory 24. The search result stored in the memory 24 is output to the sending unit 13a via the output terminal 21. The sending unit 13 a converts the search result into a format that can be delivered to the car navigation 3 and delivers the result to the car navigation 3 via the output terminal 11.
[0048]
Next, setting of the information search range in the information search range setting unit 25 of FIG. 3 will be described. FIG. 4 shows a flowchart for determining search methods 1 to 3 based on the presence / absence of current location information, destination information, and destination route information in the vehicle information. In step 500, when own vehicle information such as current location information is input from the memory 24, the process proceeds to step 501. In step 501, it is confirmed whether or not the present location information is present in the vehicle information. If there is no current location information, the process proceeds to step 502. If present, the process proceeds to step 503. In step 502, since the current location is unknown, a command for requesting the car navigation 3 to transmit current location information (referred to as current location information transmission request) is transmitted from the information search range setting unit 25.
[0049]
In step 503, it is confirmed whether the destination information is present in the vehicle information. If there is no destination information, the process proceeds to step 504, and if it exists, the process proceeds to step 505. In step 504, the destination is unknown but the current location is known, so information around the current location is searched. (Search Method 1) The range setting as shown in FIGS. 16 to 19 used for the description when there is traveling direction information and moving speed information as own vehicle information below corresponds to this. FIG. 16 shows a case where traveling direction information exists as own vehicle information, and FIG. 17 shows a case where there is no traveling direction information. Moreover, FIG. 18 is a case where movement speed information exists as own vehicle information, and FIG. 19 is a case where it does not exist.
[0050]
In step 505, it is confirmed whether the destination route information exists in the vehicle information. If not, the process proceeds to step 506, and if it exists, the process proceeds to step 507.
[0051]
In step 506, the current location and the destination are known and the destination route information is unknown. At this time, the car navigation 3 is considered to move at least from the current location to the destination location based on the positional relationship between the current location and the destination, and a search range is set. (Search method 2) For example, when the current location and the destination are not so far away, the intermediate point between the current location and the destination is the center of the circle as shown in FIG. 7, and the distance from the intermediate point to the current location is the radius. The search range is within the circle. Also, as shown in FIG. 8, when the distance between the current location and the destination is far, the location where the current location and the destination are connected and the current location and the destination are internally divided to 1: N (N> 0) is a circle. The search range is in the circle centered at. The value of N is set so that, for example, the point dividing the current location and the destination is about 5 km from the current location.
[0052]
The search range is not necessarily limited to a circle, and may be a sector as shown in FIGS. FIG. 9 shows an example of setting a search range when the current location and the destination are not so far apart, and the current location is in the sector with a center angle less than a right angle with the radius from the current location to the destination as the center. FIG. 10 is an example of setting a search range when the distance between the current location and the destination is long. The radius is 1 / N (N ≧ 1) of the distance from the current location to the destination centered on the current location. The center angle is within a sector shape with a right angle. N is set so that, for example, 1 / N of the distance between the current location and the destination is about 5 km. The central angle and radius of the fan shape are not necessarily limited to the above, and may be appropriately set by the information server 5 based on the information amount around the current location and the vehicle information. In other words, where the current location is an urban area, etc., where there are many information registrations and there is a large amount of information per unit area, there are many information items that match the search items. When information is registered on the information server 5 side, it may be set in advance so that the search range is set wider when the number of cases is small and the amount of information per unit area is small. Further, as will be described in detail below, when there is movement speed information as the vehicle information, the search range is wide when the movement speed is fast based on the movement speed information, and the search range when the movement speed is slow. May be set to be narrow.
[0053]
In step 507, since there is destination route information as the vehicle information, information search is performed along the destination route information as shown in FIG. (Search method 3) Even when the destination route information exists, if the current location is far from the destination, as shown in FIG. 12, from the current location to a certain point on the destination route, for example, 10 km away from the current location Is the search range. The destination route information transmitted from the car navigation 3 is, for example, a packet as shown in FIG. That is, information on the current location, the destination, and the waypoint (that is, an intersection that turns right and left) is transmitted as a packet. Also, each packet has a header, data attributes (distinguishes current location, destination, waypoint, etc.), total number of packets, number of remaining packets, date / time, latitude, longitude, range parameters (in the case of destination route information) Unused), footer, etc. The base station 2 side receives the packet and connects the latitude and longitude of each point to obtain a planned route (the destination route) from the current location to the destination.
[0054]
An example of the search range setting when there is destination route information is shown in FIGS. The current location-destination is divided, for example, every 1 km along the destination route received from the car navigation 3, and the search center point is set. Then, each information search range is set around each search center point. For example, as shown in FIG. 14, the information search range (X, Y) is set inside a square represented by X0−Xd <X <X0 + Xd and Y0−Yd <Y <Y0 + Yd. Alternatively, as shown in FIG. 15, the inside of a circle represented by (X−X0) × (X−X0) + (Y−Y0) × (Y−Y0) <R × R. The sum of the information search ranges is the information search range output to the information search unit 26. The destination route dividing method is not limited to the above.
[0055]
Furthermore, the detailed setting of the information search range when the traveling direction information is included as the vehicle information is shown in the flowchart of FIG. Step 600 is started after the information search method is determined in steps 504, 506, and 507 in FIG. 4, and the process proceeds to step 601. In step 601, it is confirmed whether or not traveling direction information exists as own vehicle information. If it exists, the process proceeds to step 602, and if not, the process proceeds to step 603.
[0056]
In step 602, since the traveling direction is known and it is known which direction it will move thereafter, the search range is set wider on the traveling direction side as shown in FIG. The search range is not necessarily limited to a circle.
[0057]
In step 603, since the direction of travel is unknown and it is not known in which direction it will move, the search range is set around the current location as shown in FIG. The search range is not necessarily limited to a circle.
[0058]
Moreover, the detailed setting of the information search range in the case of having moving speed information as own vehicle information is shown in the flowchart of FIG. In step 700, the information search method is determined in steps 504, 506, and 507 in FIG. 4, and when there is traveling direction information, the search range shown in FIG. 5 is set, and then the process proceeds to step 701. In step 701, it is confirmed whether or not the moving speed information exists as the vehicle information. If it exists, the process proceeds to step 702, and if not, the process proceeds to step 703.
[0059]
In step 702, the width of the search range is set according to the moving speed of the vehicle 1. For example, consider a case where the search range is circular as shown in FIG. When the radius of the search range is R [km] and the moving speed of the vehicle 1 is M [km / h], the search range is the circle represented by R = M × 1 [h]. Here, the search range is not necessarily limited to a circle. Moreover, it is not restricted to the above formula.
[0060]
In step 703, the search range is set as a default range. For example, the information server 5 sets in advance such that the radius is within 10 km as shown in FIG. This is not limited to a fixed radius. For example, the setting may be different depending on the location, for example, within a radius of 5 km in an urban area and within a radius of 20 km in a suburb. Further, the predetermined range is not limited to the circular shape, and may be a municipal unit.
[0061]

In addition, when the mobile communication terminal information has traveling direction information, the information search range is set wide on the traveling direction side, and when the mobile speed information is included, the information search range is set according to the moving speed. The information search range can be set according to the traveling state of the mobile communication terminal. Further, when the mobile communication terminal has destination route information indicating a route to be moved ahead as the mobile communication terminal information, an information search range along the destination route is set, and the information search is performed within the range.

[0076]
The current location, destination, and destination route information are also stored in the memory 115. In addition to the above information, the memory 115 also stores information such as the traveling direction and moving speed output from the vehicle information detection device 105 via the address information calculation unit 106 and the information processing unit 200, and is read by the communication unit 114. And sent to the information server 5.
[0077]
Conversely, the regional service information transmitted from the information server 5 is received by the communication unit 114 and stored in the memory 115. In the memory 115, the regional service information is divided into location information and detailed information. The location information and detailed information of the regional service information are processed by the image processing unit 103 inside the information processing unit 200 and displayed on the image display device 104.
[0078]
Now, a method for displaying the information transmitted from the information server 5 on the image display device 104 will be described with reference to the flowchart of FIG. The display range of the monitor screen is (0,0)-(1,1), and the map range that is actually displayed is (X1, Y1)-(X2, Y2). Here, X1 and X2 are longitudes, and Y1 and Y2 are latitudes. The position information of the i-th regional service information is assumed to be (Xi, Yi).
[0079]
When the car navigation 3 receives the search result of the regional service information from the information server 5 in step 800, the process proceeds to step 801. In step 801, the currently displayed map range is checked, and the process proceeds to step 802. The currently displayed map range is (X1, Y1)-(X2, Y2). In step 802, only information within the currently displayed map range is extracted from the received search results, and the process proceeds to step 803. In step 803, the search result (position information) is converted into coordinates on the display screen. That is, the coordinates (xi, yi) on the display screen (where 0 <xi <1, 0 <yi <1) are xi = (Xi−X1) / (X2−X1), yi = (Yi−Y1) / (Y2-Y1). Subsequently, the process proceeds to step 804. In step 804, an icon is selected according to the category of the search result, and the process proceeds to step 805. In step 805, the icon selected in step 804 is displayed overlaid on the map (xi, yi) obtained in step 803. Steps 803 to 805 are repeated by the number of information extracted in step 802.
[0080]
An example of the search result display is shown in FIG. FIG. 27 is a display example of a search result when searching for a restaurant at lunch, for example, with a white circle for a restaurant and a gray pentagon icon for a coffee shop. The icon is not limited to the geometric figure as described above, and may be any mark. The current location is also displayed on the screen, and the positional relationship with the search result is displayed in an easy-to-understand manner. The destination is not necessarily displayed depending on the search range. That is, when the search range is narrow or the number of search results is large, the search results near the current location are displayed and the destination is not displayed.
[0081]
The information sent from the information server 5 to the car navigation 3 includes detailed information in addition to the position information. Next, detailed information display will be described with reference to the flowchart of FIG.
[0082]
Step 810 proceeds to Step 811 by selecting an icon displayed on the display screen. In step 811, the display method such as the color of the selected icon is changed, and the process proceeds to step 812. In step 812, whether or not the display screen is two screens is checked. If there are two screens, the process proceeds to step 814, and if it is one screen, the process proceeds to step 813. In step 813, the display screen is divided into two screens, and the process proceeds to step 814. In step 814, the display of the position information described above is displayed on a divided screen (for example, the left screen), and the process proceeds to step 815. In step 815, the detailed information of the selected icon is read from the memory, and the process proceeds to step 816. In step 816, the detailed information read from the memory is displayed on the remaining divided screen (right screen). As described above, the position information and the detailed information are simultaneously displayed on the display screen, and the icon indicating the position information on which the detailed information is displayed is distinguished from other icons.
[0083]
When one restaurant icon is selected in the above example (FIG. 27), detailed information on the selected restaurant is obtained as shown in FIG. For example, in the case of a restaurant, the store name, address, telephone number, food, other parking lot, price, etc. are displayed on a divided screen. At this time, the icon on which the detailed information is displayed is distinguished from other icons by an arrow or a color change to clarify that the icon is selected. Here, the screen may be divided from the beginning, or may be divided by selecting an icon.
[0084]
Further, the icon selection may be automatically performed by the car navigation system instead of the user himself / herself. A method for the car navigation 3 to automatically select an icon will be described with reference to the flowchart of FIG.
[0085]
When the automatic icon selection is selected, step 820 is started and the routine proceeds to step 821. In step 821, the distance between the current location and the location information of the regional service information indicated by each icon is calculated by the following equation 1, and the process proceeds to step 822.
[0086]
[Expression 1]

[0087]
However, the distance is not limited to Equation 1. In step 822, it is confirmed whether the icon closest to the current location is the previously selected icon. If the previously selected icon is the closest icon, the process proceeds to step 821. If they are different, the process proceeds to step 823. In step 823, the icon closest to the current location is selected, and the process proceeds to step 824. In step 824, the color of the selected icon is changed, and the process proceeds to step 825. In step 825, an icon indicating position information is displayed on a divided screen (for example, the left screen), and the process proceeds to step 826. In step 826, the detailed information in which the icon is selected in step 823 is read from the memory, and the process proceeds to step 827. In step 827, the detailed information read from the memory in step 826 is displayed on the remaining divided screen (right screen), the process proceeds to step 821, and the same operation is repeated thereafter. As described above, when automatic icon selection is selected, it is possible to automatically display the local service information closest to the current location.
[0088]
In the above example, when the current location is in FIG. 29, the detailed information of the restaurant XYZ closest to the route is displayed, and when the car 1 passes the restaurant XYZ and the current location comes to FIG. Detailed information of the coffee shop ○ closest to the route is displayed. At this time, the passed icon may be displayed or hidden. The display range for icon display may be updated each time the vehicle 1 moves, or may be performed at regular time intervals or at regular distance intervals.
[0089]
In the above description, the position information and the detailed information are distributed from the information server 5 at the same time. However, the detailed information is not necessarily distributed simultaneously with the position information. Detailed information may be requested and distributed to the information server 5 by selecting an icon. If the automatic selection of the icon is set, in step 821, the second closest information is always requested in advance so that the position information and the detailed information are received simultaneously. Has the same effect.
[0090]
The mobile communication terminal according to the fourth embodiment divides the search result distributed from the information search / distribution device into position information and detailed information as described above, and visually displays the positional relationship with the current location by displaying the position information as an icon. The information is displayed in an easy-to-understand manner and the detailed information is displayed by selecting an icon, so that the user can select the information he / she desires and display it on the screen. In addition, since the nearest detailed information is automatically updated as the mobile communication terminal moves, the user can obtain the nearest detailed information without doing anything.
[0091]
Embodiment 5 FIG.
Next, a fifth embodiment of the present invention will be described with reference to FIG. FIG. 31 is a block configuration diagram of the car navigation system 3 according to the fifth embodiment. Only the configuration of the information processing unit 200 is different from the fourth embodiment.

In the communication unit 114, the information search range is read from the memory 115 together with the information search item set by the search item setting unit 116 and stored in the memory 115, and transmitted to the information server 5.
[0096]
An example of the information search range designation packet transmitted from the car navigation 3 to the information server 5 is shown in FIG. FIG. 32 shows a case where the car navigation 3 has destination route information and an information search range is set based on the destination route information. In this case, the current location, the destination, and the search center point (see FIGS. 14 and 15) are transmitted as packets. Each packet has a header, data attributes (distinguishes current location, destination, search center point, etc.), total packet count, remaining packet count, date / time, latitude, longitude, range parameters (search information for search center location) (One side of a quadrangle for specifying a range or the radius of a circle), a footer, and the like. In addition, when the information search range is determined based on the traveling speed information and the moving speed information, the current location is specified by the data attribute, and the circle, sector radius, sector central angle (when the search range is circular or sector) are set as above. Send as a range parameter. The packet is generated by the information search range setting unit 25.
[0097]
The information server 5 retrieves information from the transmitted information retrieval range and information retrieval item, and transmits the retrieval result to the car navigation 3.
[0098]
The regional service information transmitted from the information server 5 is received by the communication unit 114 and stored in the memory 115. In the memory 115, the regional service information is divided into location information and detailed information. The location information and detailed information of the regional service information are processed by the image processing unit 103 inside the information processing unit 200 and displayed on the image display device 104.

[0106]
Further, although GPS is used as means for measuring the current location of the mobile communication terminal, the present invention is not limited to this. Needless to say, even if there is no way of knowing the current location on the mobile communication terminal side such as a transmitter, the same effect can be obtained if the current location of the mobile communication terminal can be confirmed at the base station. Needless to say, the same effect can be obtained when the location of the PHS is known on a cell basis during communication, such as PHS (refers to a personal handy phone).
[0107]
In addition, if the current location is not accurately known, that is, if the latitude, longitude, and altitude are not known, the mobile communication terminal can select the current location address or facility name and notify the base station. It goes without saying that the information retrieval from 1 to the fourth embodiment and the fifth embodiment can be performed.
[0108]
In the fourth embodiment and the fifth embodiment, the car navigation itself has a communication function, but it is not always necessary to be built in the car navigation. It is also possible to connect the car navigation system and the communication device with an adapter, notify various information from the car navigation system to the base station through the communication device, and similarly distribute the search result to the car navigation system through the communication device. This is the same when a PDA, HPC or the like is used as a mobile communication terminal.
[0109]
In addition, the information that the information server 5 searches for the search items from the mobile communication terminal in the first to third embodiments is not limited to the information that the information server 5 stores locally.
