　近年、情報通信技術が種々の情報媒体に活用され、多くの情報が様々な情報媒体を介して利用者に配信されている。このような状況は、利用者が多くの情報を享受することができるメリットがある一方で、氾濫する情報から必要な情報を必要な局面で取得することが困難となるデメリットを生んでいる。このため、移動端末の利用者にとって有用な情報を自動的に選別し提供する、または配信予定の情報を必要としている利用者の移動端末を自動的に選別する情報処理システムの開発が多々なされてきた。 In recent years, information communication technology has been utilized for various information media, and a lot of information has been distributed to users via various information media. Such a situation has a merit that the user can enjoy a lot of information, but has a disadvantage that it is difficult to obtain necessary information from the flooded information in a necessary situation. For this reason, many information processing systems have been developed that automatically select and provide useful information for users of mobile terminals, or automatically select the mobile terminals of users who need information to be distributed. It was.
　この種のシステムとして、特許文献１（特開２００５－２２８１５４号公報）には、次のようなシステムが開示されている。このシステムは、移動端末の利用者が滞在した位置の履歴に基づいて新たなコンテキストを生成し、当該利用者に生成したコンテキストを提供することができる。さらに、各移動端末から常時位置情報を受信し、複数の移動端末が連続して近傍に滞在していることを同伴行動として検知し、同伴行動の頻度や時間等からコンテキストを生成することもできる。 As this type of system, Patent Document 1 (Japanese Patent Laid-Open No. 2005-228154) discloses the following system. This system can generate a new context based on the history of the location where the user of the mobile terminal stayed, and can provide the generated context to the user. Furthermore, it is also possible to receive location information from each mobile terminal at all times, detect that a plurality of mobile terminals are continuously staying in the vicinity as accompanying actions, and generate a context from the frequency and time of the accompanying actions. .

When requesting information provision from one mobile terminal to another mobile terminal via a service center, this system automatically sends another mobile terminal that transmits an information provision request according to the content of the requested information. It is possible to execute a search process for searching. In addition, this system requests information provision by dividing mobile terminals that can be communicated by the service center into several groups based on information input to the mobile terminals by the user in advance of performing the search process. Search processing can be executed for mobile terminals belonging to the same group as the mobile terminal. Thus, the search process can be performed quickly and reliably.

　〔第１の実施形態〕
　図１は、第１の実施形態の情報処理システム１００の構成を示すブロック図である。図１を参照すると、第１の実施の形態は、利用者が携行する複数の移動端末１１、１２、及び１３と、移動端末１１、１２、及び１３を介して利用者に情報提供を行う情報提供サーバ２０（情報処理装置）とから構成されている。情報提供サーバ２０は、受信部２１と、移動履歴記憶部２２と、相互関係抽出部２３（第１比較手段）と、相互関係記憶部２４と、同一組検索部２５（第１取得手段、第２取得手段および第２比較手段）と、コンテンツ送信部２６と、を含む。 [First Embodiment]
FIG. 1 is a block diagram illustrating a configuration of an information processing system 100 according to the first embodiment. Referring to FIG. 1, in the first embodiment, a plurality of mobile terminals 11, 12, and 13 carried by a user and information for providing information to the user via the mobile terminals 11, 12, and 13 are provided. It is comprised from the provision server 20 (information processing apparatus). The information providing server 20 includes a receiving unit 21, a movement history storage unit 22, a correlation extracting unit 23 (first comparison unit), a correlation storage unit 24, and the same set search unit 25 (first acquisition unit, first acquisition unit). 2 acquisition means and second comparison means) and a content transmission unit 26.
　複数の移動端末１１、１２、及び１３はそれぞれ、自機の位置を示す位置情報と、自機を示す識別情報（自機識別情報）と、を間欠的に送信することができれば、その形態はいずれでも構わない。例えば、移動端末１１、１２、及び１３は、携帯電話、ＰＨＳ、カーナビゲーション機器等である。図１では、移動端末１１、１２、及び１３は三台を図示しているが、複数であれば何台であってもよい。また、移動端末１１、１２、及び１３は必ずしも同種の装置でなくてもよい。 If each of the plurality of mobile terminals 11, 12, and 13 can intermittently transmit position information indicating the position of the own device and identification information (own device identification information) indicating the own device, the form is Either is fine. For example, the mobile terminals 11, 12, and 13 are mobile phones, PHS, car navigation devices, and the like. In FIG. 1, three mobile terminals 11, 12, and 13 are illustrated. Further, the mobile terminals 11, 12, and 13 do not necessarily have to be the same type of device.
　なお、本実施形態において移動端末１１、１２、及び１３は、自機が有する測位機能によって位置情報を得てもよいし、他の装置から自機の位置情報を得てもよい。また、識別情報とは、移動端末１１、１２、及び１３の固有識別情報であって、製造番号や電話番号、メールアドレス、移動端末の利用者名、移動端末に割り当てられたシーケンス番号等である。本実施形態においては、一様に識別情報として説明するが、識別情報は、情報提供サーバ２０内の処理段階ごとに異なる形態を採ってもよい。例えば、情報提供サーバ２０内の処理途中で、識別情報は製造番号から移動端末の利用者名に変換されてもよい。さらに、位置情報とは、移動端末１１、１２、及び１３の位置を示す情報であって、緯度および経度、通信中の基地局等で示される。 In addition, in this embodiment, the mobile terminals 11, 12, and 13 may obtain position information by a positioning function of the own apparatus, or may obtain position information of the own apparatus from other devices. The identification information is unique identification information of the mobile terminals 11, 12, and 13, and includes a manufacturing number, a telephone number, a mail address, a user name of the mobile terminal, a sequence number assigned to the mobile terminal, and the like. . In this embodiment, although it demonstrates as identification information uniformly, identification information may take a different form for every process step in the information provision server 20. FIG. For example, the identification information may be converted from the serial number into the user name of the mobile terminal during the processing in the information providing server 20. Further, the position information is information indicating the positions of the mobile terminals 11, 12, and 13 and is indicated by latitude and longitude, a base station in communication, and the like.
　識別情報は、移動端末１１、１２、及び１３の形態によって種々の形態を採りうる。そして、間欠的とは、一定の周期で繰り返すことであってもよいし、不定の周期で繰り返すことであってもよい。さらに、移動端末１１、１２、及び１３は、位置情報と識別情報以外の種々の情報を送信してもよく、例えば、位置情報に対応する時刻情報や、自機が有している他の移動端末の識別情報（他機識別情報）等を送信してもよい。 The identification information can take various forms depending on the forms of the mobile terminals 11, 12, and 13. And intermittent may be repeating with a fixed period, and may be repeating with an indefinite period. Furthermore, the mobile terminals 11, 12, and 13 may transmit various information other than the position information and the identification information. For example, time information corresponding to the position information and other movements that the own device has. Terminal identification information (other machine identification information) or the like may be transmitted.
　受信部２１は、情報提供サーバ２０の外部ネットワーク（図示せず）または外部機器（図示せず）から到来する情報を受信することができる機能を有する。本実施形態における受信部２１は、複数の移動端末１１、１２、及び１３の各々から、移動端末自体の位置を示す位置情報と、当該位置情報に対応する移動端末１１、１２、又は１３を識別する識別情報と、を間欠的に受信する。なお、受信部２１は、各移動端末１１、１２、及び１３から位置情報と識別情報とを直接的に受信してもよいし、図１に図示しない種々の装置やネットワーク等を介して間接的に受信してもよい。また、受信部２１は、移動端末１１、１２、及び１３によって送信された位置情報と識別情報以外の種々の情報を受信してもよい。 The receiving unit 21 has a function of receiving information coming from an external network (not shown) or an external device (not shown) of the information providing server 20. The receiving unit 21 in the present embodiment identifies position information indicating the position of the mobile terminal itself and the mobile terminal 11, 12, or 13 corresponding to the position information from each of the plurality of mobile terminals 11, 12, and 13. And identification information to be received intermittently. The receiving unit 21 may directly receive the position information and the identification information from each mobile terminal 11, 12, and 13, or indirectly via various devices, networks, etc. not shown in FIG. May be received. The receiving unit 21 may receive various information other than the position information and identification information transmitted by the mobile terminals 11, 12, and 13.
　移動履歴記憶部２２は、情報提供サーバ２０内に備えられた記憶媒体に含まれる記憶領域である。本実施形態における移動履歴記憶部２２は、受信部２１によって受信された位置情報と識別情報とを関係付けて記憶する。また、移動履歴記憶部２２は、受信部２１によって受信された位置情報と識別情報以外の種々の情報を、それぞれに対応する位置情報と識別情報と関係付けて記憶してもよい。 The movement history storage unit 22 is a storage area included in a storage medium provided in the information providing server 20. The movement history storage unit 22 in the present embodiment stores the positional information received by the receiving unit 21 and the identification information in association with each other. The movement history storage unit 22 may store various information other than the position information and identification information received by the reception unit 21 in association with the corresponding position information and identification information.
　本実施形態における相互関係抽出部２３は、移動履歴記憶部２２に記憶された位置情報のうち、一の識別情報に関係付けられた位置情報と、他の識別情報に関係付けられた位置情報と、を比較する比較処理（第１比較処理）を実行し、一の識別情報と他の識別情報との間の相互関係の有無を判定する。ここで、実行される第１比較処理は、後述する検索処理の事前処理であって、過去の位置情報に基づいて、検索処理によって同一組として検索される可能性の高いと判定される識別情報同士を関係付けて相互関係記憶部２４に記憶しておくことを目的とした処理である。 The correlation extracting unit 23 in the present embodiment includes the positional information related to one identification information and the positional information related to other identification information among the positional information stored in the movement history storage unit 22. Are compared to determine whether or not there is a mutual relationship between one piece of identification information and another piece of identification information. Here, the first comparison process to be executed is a pre-process of a search process to be described later, and identification information that is determined to be highly likely to be searched as the same set by the search process based on past position information This is a process aimed at associating them with each other and storing them in the correlation storage unit 24.
　相互関係記憶部２４は、移動履歴記憶部２２と同様に、情報提供サーバ２０内に備えられた記憶媒体に含まれる記憶領域である。本実施形態における相互関係記憶部２４は、相互関係抽出部２３によって実行された比較処理の判定結果に応じて、一の識別情報と他の識別情報とを関係付けて記憶する。 Similar to the movement history storage unit 22, the interrelation storage unit 24 is a storage area included in a storage medium provided in the information providing server 20. In the present embodiment, the correlation storage unit 24 stores one identification information and other identification information in association with each other according to the determination result of the comparison process executed by the correlation extraction unit 23.
　相互関係抽出部２３は、第１比較処理を間欠的に実行するが、その頻度は、受信部２１が位置情報と識別情報を受信する頻度より少ないことが望ましく、移動端末１１（または１２、１３）が位置情報と識別情報とを送信する頻度より少ないことが望ましい。第１比較処理が実行されると、前回の第１比較処理が実行された後に移動履歴記憶部２２に追加された位置情報と識別情報とに基づいて、相互関係記憶部２４に記憶されている各識別情報間の関係が更新または追加される。従って、上記の理由は、新たに位置情報と識別情報とが移動履歴記憶部２２に記憶される前に、第１比較処理が実行されても意味を為さないからである。よって、例えば、相互関係抽出部２３は、移動端末１１、１２、及び１３の利用者があまり移動しないであろう時間帯（深夜等）にバッチ処理で第１比較処理を実行する。 The correlation extracting unit 23 intermittently executes the first comparison process, but the frequency is preferably less than the frequency at which the receiving unit 21 receives the position information and the identification information, and the mobile terminal 11 (or 12, 13). ) Is preferably less than the frequency of transmitting position information and identification information. When the first comparison process is executed, the first comparison process is stored in the correlation storage unit 24 based on the position information and the identification information added to the movement history storage unit 22 after the previous first comparison process is executed. The relationship between each identification information is updated or added. Therefore, the above reason is because it does not make sense to execute the first comparison process before the position information and the identification information are newly stored in the movement history storage unit 22. Therefore, for example, the correlation extracting unit 23 executes the first comparison process by batch processing in a time zone (such as midnight) in which the users of the mobile terminals 11, 12, and 13 will not move much.
　本実施形態における同一組検索部２５は、受信部２１が新規の位置情報と新規の識別情報とを受信したとき、以下の処理を実行することによって、当該新規の識別情報と同一組の識別情報を検索することができる。 When the receiving unit 21 receives new position information and new identification information, the same set search unit 25 according to the present embodiment executes the following process to identify the same set of identification information as the new identification information. Can be searched.
　同一組検索部２５は、新規の識別情報と同じ識別情報と関係付けられ記憶されている識別情報を相互関係記憶部２４から取得する（第１取得処理）。次に、同一組検索部２５は、第１取得処理で取得された識別情報に関連付けられた位置情報を移動履歴記憶部２２から取得する（第２取得処理）。そして、同一組検索部２５は、第２取得処理で取得された位置情報と、新規の位置情報とを比較する比較処理（第２比較処理）を実行し、第２比較処理の判定結果に応じて、第２取得処理で取得された位置情報のうち少なくとも一つを選択し、選択された位置情報に関連付けられた識別情報を出力する。例えば、受信部２１から新規の位置情報と新規の識別情報とを受け付けた都度、同一組検索部２５は、上記の一連の処理を逐次処理で実行する。 The same set search unit 25 acquires the identification information associated with the same identification information as the new identification information and stored from the correlation storage unit 24 (first acquisition process). Next, the same set search unit 25 acquires position information associated with the identification information acquired in the first acquisition process from the movement history storage unit 22 (second acquisition process). And the same set search part 25 performs the comparison process (2nd comparison process) which compares the position information acquired by the 2nd acquisition process, and new position information, and responds to the determination result of the 2nd comparison process. Then, at least one of the position information acquired in the second acquisition process is selected, and the identification information associated with the selected position information is output. For example, each time new position information and new identification information are received from the receiving unit 21, the same set search unit 25 executes the above-described series of processes in a sequential process.
　コンテンツ送信部２６は、新規の識別情報が示す移動端末、及び同一組検索部２５によって選択された識別情報が示す移動端末の少なくとも一方に対して、当該移動端末が可読なコンテンツを送信する。ここで、移動端末が可読なコンテンツとは、移動端末が情報処理可能なデータまたはプログラム等である。移動端末は、受信したコンテンツを処理して表示出力してもよいし、音声出力してもよいし、印刷出力してもよいし、出力せずに内部処理に用いてもよい。なお、コンテンツ送信部２６によって送信されるコンテンツは、第１比較処理や第２比較処理の判定基準に適合した内容であることが好ましい。 The content transmission unit 26 transmits content readable by the mobile terminal to at least one of the mobile terminal indicated by the new identification information and the mobile terminal indicated by the identification information selected by the same set search unit 25. Here, the content readable by the mobile terminal is data or a program that can be processed by the mobile terminal. The mobile terminal may process and display the received content, output it by voice, print it out, or use it for internal processing without outputting it. Note that the content transmitted by the content transmission unit 26 is preferably content that conforms to the determination criteria of the first comparison process and the second comparison process.
　コンテンツ送信部２６によって送信されるコンテンツは、情報提供サーバ２０内に備えられているデータベース（図示せず）に保有されてもよいし、他の装置や他のネットワーク（図示せず）から取得されてもよい。特に、コンテンツ送信部２６は、第１比較処理または第２比較処理の判定条件に応じてコンテンツを検索する機能を有していることが望ましい。 The content transmitted by the content transmission unit 26 may be held in a database (not shown) provided in the information providing server 20, or acquired from another device or another network (not shown). May be. In particular, the content transmission unit 26 desirably has a function of searching for content according to the determination condition of the first comparison process or the second comparison process.
　上述した情報提供サーバ２０に含まれる構成の全部または一部は、ハードウェアで実現されてもよいし、あるいは、プロセッサに処理を実行させるプログラム（またはプログラムコード）で実現されてもよい。プロセッサは、不揮発性メモリなどの記録媒体からそのプログラムを読み出し実行する。 All or part of the configuration included in the information providing server 20 described above may be realized by hardware, or may be realized by a program (or program code) that causes a processor to execute processing. The processor reads and executes the program from a recording medium such as a nonvolatile memory.
　図２は、移動履歴記憶部２２に記憶されるテーブルを示す図である。ここで、図２の例において、移動端末１１の識別情報は「００１１」、移動端末１２の識別情報は「００１２」、移動端末１３の識別情報は「００１３」と仮定する。また、図２の例によれば、夫々の位置情報は、緯度と経度とで示される。さらに、図２の例で示されるテーブルには、夫々の位置情報に対応する時刻情報も保有される。ここで、位置情報に対応する時刻情報とは、位置情報が測位された時刻を示す情報であってもよいし、受信部２１によって位置情報が受信された時刻を示す情報であってもよい。なお、ここで示すテーブルは一例であって、必ずしも図示するフォーマットである必要はない。 FIG. 2 is a diagram showing a table stored in the movement history storage unit 22. In the example of FIG. 2, it is assumed that the identification information of the mobile terminal 11 is “0011”, the identification information of the mobile terminal 12 is “0012”, and the identification information of the mobile terminal 13 is “0013”. Moreover, according to the example of FIG. 2, each positional information is shown with the latitude and the longitude. Furthermore, the table shown in the example of FIG. 2 also holds time information corresponding to each position information. Here, the time information corresponding to the position information may be information indicating the time when the position information is measured, or may be information indicating the time when the position information is received by the receiving unit 21. Note that the table shown here is an example and does not necessarily have the format shown.
　図３は、相互関係記憶部２４に記憶されるテーブルを示す図である。ここで、「００１１」「００１２」「００１３」以外の識別情報は、図１で図示されない移動端末の識別情報であると仮定する。相関関係抽出部２３によって相関関係有りと判定された移動端末の識別情報同士は、同じ行に格納される。図３の例では、最も左の列に格納される識別情報（図３における第１の識別情報）を基準として、基準となる識別情報と相関関係有りと判定された識別情報が、同じ行に格納されている。なお、図３には第１～第３の識別情報を図示しているが、同一行に四つ以上の識別情報が格納されてもよい。また、ここで示すテーブルは一例であって、必ずしも図示するフォーマットである必要はない。例えば、相関関係抽出部２３によって相関関係有りと判定される度に新たな行を追加し、判定の対象となった少なくとも二つの識別情報を追加した行に夫々格納するようにしてもよい。 FIG. 3 is a diagram showing a table stored in the correlation storage unit 24. Here, it is assumed that identification information other than “0011”, “0012”, and “0013” is identification information of a mobile terminal not shown in FIG. Identification information of mobile terminals determined to have a correlation by the correlation extraction unit 23 is stored in the same row. In the example of FIG. 3, the identification information determined to have a correlation with the reference identification information is stored in the same row with reference to the identification information stored in the leftmost column (first identification information in FIG. 3). Stored. Although FIG. 3 shows the first to third identification information, four or more identification information may be stored in the same row. Further, the table shown here is an example, and it is not always necessary to have the format shown in the figure. For example, a new row may be added each time it is determined that there is a correlation by the correlation extraction unit 23, and at least two pieces of identification information to be determined may be stored in the added rows.
　なお、相互関係抽出部２３が実行する第１比較処理とはどのような処理であって、どのような判定のとき、相互関係記憶部２４は一の識別情報と他の識別情報とを関係付けて記憶するのかという点について、本実施形態は多様な形態を採りうる。どのような関係性を有する移動端末同士またはその利用者同士を関係付け、どのようなコンテンツを当該利用者に提供するのかによって、その形態は適切に選択されればよい。 In addition, what kind of process is the first comparison process executed by the correlation extraction unit 23, and what kind of determination is made, the correlation storage unit 24 associates one identification information with another identification information. This embodiment can take various forms with respect to whether or not to store the information. The form may be appropriately selected depending on what kind of relationship between mobile terminals or their users and what kind of contents are provided to the users.
　例えば、第１比較処理は、一の識別情報に関連付けられた複数の位置情報から成る第１データ群と、他の識別情報に関連付けられた複数の位置情報から成る第２データ群と、を比較することであってもよい。より詳細には、第１比較処理は、メッシュ状に区分された二次元空間上に第１データ群と第２データ群とを配置したとき、第１データ群の位置情報と、第２データ群の位置情報とが共に配置されたメッシュの数によって一致度を算出してもよい。このように処理することで、移動端末の移動経路の類似性に応じて同一組となる識別情報を検索することができるので、移動中の移動端末に対して本実施形態を適用する場合に適している。また、各々の移動端末が位置情報を送信（測位）するタイミングが異なる状況であっても、比較的高い精度で比較することができる。 For example, in the first comparison process, a first data group composed of a plurality of position information associated with one identification information is compared with a second data group composed of a plurality of position information associated with other identification information. It may be to do. More specifically, in the first comparison process, when the first data group and the second data group are arranged in a two-dimensional space divided in a mesh shape, the position information of the first data group and the second data group The degree of coincidence may be calculated based on the number of meshes arranged together with the position information. By performing processing in this way, it is possible to search for the same set of identification information according to the similarity of the movement route of the mobile terminal, which is suitable when the present embodiment is applied to a moving mobile terminal. ing. Further, even when each mobile terminal transmits the position information (positioning) at different timings, the comparison can be performed with relatively high accuracy.
　または、受信部２１が位置情報と自機識別情報と他機識別情報とを受信し、移動履歴記憶部２２は、更に自機識別情報と他機識別情報とを関連付けて記憶する場合、第１比較処理は、一の自機識別情報に関係付けられた位置情報と、当該一の自機識別情報に関連付けられた他機識別情報によって示される移動端末を示している他の自機識別情報に関係付けられた位置情報と、を比較することであってもよい。 Alternatively, the receiving unit 21 receives the position information, the own device identification information, and the other device identification information, and the movement history storage unit 22 further stores the first device identification information and the other device identification information in association with each other. In the comparison process, the position information associated with the one apparatus identification information and the other apparatus identification information indicating the mobile terminal indicated by the other apparatus identification information associated with the one apparatus identification information. It may be to compare the related positional information.
　より具体的には、例えば、移動端末１１、１２、及び１３がいずれも携帯電話機であったとする。移動端末１１の着信履歴や受信メールとして、移動端末１２の電話番号やメールアドレス等が残っている場合、移動端末１１は自機の識別情報と、移動端末１２の識別情報とを送信することができる。その後、相互関係抽出部２３は、移動端末１１の識別情報に関連付けられた位置情報と、移動端末１２の識別番号に関連付けられた位置情報とを比較することによって第１比較処理を実行することができる。このように、移動端末が保有している他機の識別情報を用いて第１比較処理を実行することで、より強い人間関係のある利用者が使用している移動端末の識別情報同士を関係付けて、相互関係記憶部２４に記憶させることができる。 More specifically, for example, it is assumed that the mobile terminals 11, 12, and 13 are all mobile phones. If the telephone number or mail address of the mobile terminal 12 remains as the incoming history or received mail of the mobile terminal 11, the mobile terminal 11 may transmit its own identification information and the identification information of the mobile terminal 12. it can. Thereafter, the correlation extracting unit 23 may execute the first comparison process by comparing the position information associated with the identification information of the mobile terminal 11 and the position information associated with the identification number of the mobile terminal 12. it can. In this way, by executing the first comparison process using the identification information of the other device held by the mobile terminal, the identification information of the mobile terminal used by a user with a stronger human relationship is related. In addition, it can be stored in the correlation storage unit 24.
　または、受信部２１は、各々の移動端末から更に、位置情報に対応する時刻情報を受信し、移動履歴記憶部２２は、位置情報と識別情報と時刻情報とを関連付けて記憶する場合、第１比較処理は、時間帯情報を取得し、当該時間帯情報の時間帯を示す時刻情報に関連付けられた位置情報同士を比較することであってもよい。より具体的には、通勤時間が設定入力されている場合、相互関係抽出部２３が、通勤の時間帯に含まれる時刻を示す時刻情報に関係付けられた位置情報同士を比較することによって、同じ通勤経路を利用している利用者同士の移動端末の識別情報を関係付けて相互関係記憶部２４に記憶させること等ができる。 Alternatively, the receiving unit 21 further receives time information corresponding to the position information from each mobile terminal, and the movement history storage unit 22 stores the position information, the identification information, and the time information in association with each other. The comparison process may be to acquire time zone information and compare position information associated with time information indicating the time zone of the time zone information. More specifically, when the commuting time is set and input, the correlation extracting unit 23 compares the positional information related to the time information indicating the time included in the commuting time zone, thereby obtaining the same. The identification information of the mobile terminals between users using the commuting route can be related and stored in the correlation storage unit 24.
　ここで、時間帯情報は、情報提供サーバ２０にデフォルトで設定された値であってもよいし、移動端末１１（または１２、１３）の利用者によって入力された値であってもよいし、情報提供サーバ２０の管理者によって入力された値であってもよい。 Here, the time zone information may be a value set by default in the information providing server 20, or may be a value input by the user of the mobile terminal 11 (or 12, 13). It may be a value input by the administrator of the information providing server 20.
　また、上記と同様に、受信部２１は、各々の移動端末から更に、位置情報に対応する時刻情報を受信し、移動履歴記憶部２２は、位置情報と識別情報と時刻情報とを関連付けて記憶する場合、同一組検索部２５（第２取得処理）は、第１取得処理によって取得された識別情報に関連付けられ、かつ新規の位置情報に対応する時刻情報が示す時刻を基準として所定の時間差に収まる時刻情報に対応する位置情報を、移動履歴記憶部２２から取得してもよい。 Similarly to the above, the receiving unit 21 further receives time information corresponding to the position information from each mobile terminal, and the movement history storage unit 22 stores the position information, the identification information, and the time information in association with each other. In this case, the same set search unit 25 (second acquisition process) uses a predetermined time difference based on the time indicated by the time information associated with the identification information acquired by the first acquisition process and corresponding to the new position information. The position information corresponding to the time information to be stored may be acquired from the movement history storage unit 22.
　さらには、第１比較処理は、一の識別情報に関係付けられた位置情報が示す位置と、他の識別情報に関係付けられた位置情報が示す位置との距離を算出し、距離に応じて判定してもよい。当然、算出された距離が所定の閾値以下（未満）であるときに双方の位置情報を関連付けて相互関係記憶部２４に記憶してもよいし、算出された距離が所定の閾値以上である（または所定の閾値を超える）ときに双方の位置情報を関連付けて相互関係記憶部２４に記憶してもよい。 Further, the first comparison process calculates a distance between the position indicated by the position information related to the one identification information and the position indicated by the position information related to the other identification information, and according to the distance You may judge. Of course, when the calculated distance is equal to or less than a predetermined threshold (less than), both pieces of positional information may be associated and stored in the correlation storage unit 24, or the calculated distance is equal to or greater than a predetermined threshold ( Alternatively, when the predetermined threshold value is exceeded, both pieces of positional information may be associated and stored in the correlation storage unit 24.
　算出された距離が所定の閾値以下（または所定の閾値未満）であることを判定条件とする場合、例えば、コンテンツ送信部２６から待ち合わせ案内に関する情報をコンテンツとして各移動端末に送信するシステム等に好適である。また、算出された距離が所定の閾値以上である（を超える）ことを判定条件とする場合、例えば、夜間の徘徊癖がある方に移動端末を持たせて、徘徊を検出して他の移動端末に報知するシステム等に好適である。 When the determination condition is that the calculated distance is equal to or less than a predetermined threshold (or less than a predetermined threshold), for example, it is suitable for a system that transmits information on meeting guidance from the content transmission unit 26 to each mobile terminal as content. It is. In addition, when the determination condition is that the calculated distance is equal to or greater than (or exceeds) a predetermined threshold, for example, a person with a night habit has a mobile terminal to detect the hail and perform other movements. It is suitable for a system that notifies a terminal.
　相互関係抽出部２３が、位置と、当該位置の属するカテゴリとが関係付けられた地図情報を記憶しているのであれば、第１比較処理は、一の識別情報に関係付けられた位置情報によって示される位置が属しているカテゴリと、他の識別情報に関係付けられた位置情報によって示される位置が属しているカテゴリとを比較し、互いに一致するか否かを判定してもよい。ここで、地図情報とは、例えば、座標位置と、当該座標位置に位置する建物や施設等と、を関連付けている情報である。本実施形態において、地図情報は必ずしも人間が可視的に認知可能なように表示出力できなくてもよい。 If the interrelation extraction unit 23 stores map information in which a position and a category to which the position belongs are stored, the first comparison process is performed based on position information related to one piece of identification information. The category to which the indicated position belongs may be compared with the category to which the position indicated by the position information related to other identification information belongs to determine whether or not they match each other. Here, the map information is, for example, information that associates a coordinate position with a building or facility located at the coordinate position. In the present embodiment, the map information may not necessarily be displayed and output so that a human can visually recognize it.
　より具体的には、一の識別情報に関係付けられた位置情報と他の識別情報に関係付けられた位置情報とが、Ａ社の事業所に集中しているような場合、双方の位置情報は「Ａ社」というカテゴリで一致すると判定されてもよい。また、このような場合に、コンテンツ送信部２６から送信されるコンテンツは、上記カテゴリに即した内容の情報であることが好ましい。 More specifically, when the location information related to one identification information and the location information related to other identification information are concentrated in the office of company A, both location information May be determined to match in the category “Company A”. In such a case, it is preferable that the content transmitted from the content transmission unit 26 is information of contents in accordance with the above category.
　上述した第１比較処理の判定条件の例示は、いずれか１つを用いてもよいし、いずれか複数を組み合わせて用いてもよい。また、ここで例示した第１比較処理の判定条件は、第２比較処理の判定条件としても同様に適用することが可能である。しかし、第２比較処理の判定条件を少なくすることによって、同一組検索部２５の処理速度の向上を図ることができるので、本実施形態においてはその詳細は説明しない。 Any one of the determination conditions of the first comparison process described above may be used, or any of them may be used in combination. Further, the determination conditions of the first comparison process exemplified here can be similarly applied as the determination conditions of the second comparison process. However, since the processing speed of the same group search unit 25 can be improved by reducing the determination conditions of the second comparison process, details thereof will not be described in the present embodiment.
　図４は、第１の実施形態の情報処理方法を示す流れ図である。図４を参照して本実施の形態の全体の動作について説明する。 FIG. 4 is a flowchart showing the information processing method of the first embodiment. The overall operation of the present embodiment will be described with reference to FIG.
　情報提供サーバ２０は、複数の移動端末１１、１２、及び１３の各々から、移動端末自体の位置を示す位置情報と、当該位置情報に対応する移動端末１１、１２、又は１３を識別する識別情報と、を受信すると（ステップＳ２のＹＥＳ）、受信された位置情報と識別情報とを関係付けて記憶する（ステップＳ３）。なお、情報提供サーバ２０は、位置情報と識別情報とを受信しない間（ステップＳ２のＮＯ）、待機状態となる。 The information providing server 20 includes, from each of the plurality of mobile terminals 11, 12, and 13, position information indicating the position of the mobile terminal itself, and identification information for identifying the mobile terminal 11, 12, or 13 corresponding to the position information. Are received (YES in step S2), the received position information and identification information are stored in association with each other (step S3). Note that the information providing server 20 is in a standby state while not receiving the position information and the identification information (NO in step S2).
　情報提供サーバ２０は、ステップＳ３で記憶された位置情報と識別情報の少なくとも一部に対して、第１比較処理が実行済みであるとき（ステップＳ４のＹＥＳ）、ステップＳ１１で記憶された識別情報のうち、ステップＳ２で受信した新規の識別情報と同じ識別情報と関係付けられ記憶されている識別情報を取得する（ステップＳ５）。次に、情報提供サーバ２０は、ステップＳ３で記憶された複数の位置情報のうち、ステップＳ５で取得された識別情報に関連付けられた位置情報を取得する（ステップＳ６）。そして、情報提供サーバ２０は、ステップＳ６で取得された位置情報と、新規の位置情報とを比較する第２比較処理を実行し、第２比較処理の判定結果に応じて、ステップＳ６で取得された位置情報のうち少なくとも一つを検索し、検索された位置情報に関連付けられた識別情報を、新規の識別情報の同一組とする（ステップＳ７）。そして、情報提供サーバ２０は、新規の識別情報が示す移動端末、及びステップＳ７で当該新規の識別情報の同一組として検索された識別情報が示す移動端末の少なくとも一方（本実施形態においては移動端末１１、１２、及び１３のいずれか）に対して、当該移動端末が可読なコンテンツを送信する（ステップＳ８）。なお、第１比較処理が未実行であるとき（ステップＳ４のＮＯ）、およびステップＳ８の後は、ステップＳ９に移行する。 When the first comparison process has been executed for at least part of the position information and the identification information stored in step S3 (YES in step S4), the information providing server 20 stores the identification information stored in step S11. Among these, the identification information stored in association with the same identification information as the new identification information received in step S2 is acquired (step S5). Next, the information providing server 20 acquires position information associated with the identification information acquired in step S5 among the plurality of position information stored in step S3 (step S6). And the information provision server 20 performs the 2nd comparison process which compares the position information acquired by step S6, and new position information, and is acquired by step S6 according to the determination result of a 2nd comparison process. At least one of the obtained position information is searched, and the identification information associated with the searched position information is set as the same set of new identification information (step S7). The information providing server 20 is at least one of the mobile terminal indicated by the new identification information and the mobile terminal indicated by the identification information retrieved as the same set of the new identification information in step S7 (in this embodiment, the mobile terminal 11, 12, and 13), the mobile terminal transmits content that can be read by the mobile terminal (step S <b> 8). When the first comparison process is not executed (NO in step S4) and after step S8, the process proceeds to step S9.
　第１比較処理を実行するタイミングであるとき（ステップＳ９のＹＥＳ）、情報提供サーバ２０は、ステップＳ３で記憶された位置情報のうち、一の識別情報に関係付けられた位置情報と、他の識別情報に関係付けられた位置情報と、を比較する第１比較処理を実行する（ステップＳ１０）。そして、情報提供サーバ２０は、第１比較処理の判定結果に応じて、一の識別情報と他の識別情報とを関係付けて記憶する（ステップＳ１１）。なお、第１比較処理を実行するタイミングではないとき（ステップＳ９のＮＯ）、およびステップＳ１１の後は、ステップＳ１に移行する。 When it is time to execute the first comparison process (YES in step S9), the information providing server 20 compares the position information related to one identification information among the position information stored in step S3, A first comparison process is performed for comparing the positional information associated with the identification information (step S10). Then, the information providing server 20 stores the one identification information and the other identification information in association with each other according to the determination result of the first comparison process (step S11). When it is not time to execute the first comparison process (NO in step S9) and after step S11, the process proceeds to step S1.
　ここで、ステップＳ１０が実行される頻度（ステップＳ９でＹＥＳとなる頻度）は、ステップＳ２でＹＥＳとなる頻度より少ないことが望ましい。 Here, it is desirable that the frequency at which step S10 is executed (the frequency at which YES is determined at step S9) be less than the frequency at which YES is determined at step S2.
　情報提供サーバ２０を停止させるべきとき（ステップＳ１のＹＥＳ）、この流れ図で示す情報提供サーバ２０の動作は終了となる。また、情報提供サーバ２０の稼動を継続するとき（ステップＳ１のＮＯ）、情報提供サーバ２０は、再び位置情報と識別情報とを受信するまで待機状態となる。なお、情報提供サーバ２０を停止させるべきときとは、情報提供サーバ２０の電源を切るときや、情報提供サーバ２０と移動端末１１、１２、１３との間で通信不能になったとき等である。 When the information providing server 20 should be stopped (YES in step S1), the operation of the information providing server 20 shown in this flowchart is terminated. Further, when the operation of the information providing server 20 is continued (NO in step S1), the information providing server 20 is in a standby state until it receives the position information and the identification information again. The time when the information providing server 20 should be stopped is when the information providing server 20 is turned off or when communication between the information providing server 20 and the mobile terminals 11, 12, 13 is disabled. .
　ここで、本実施形態の効果について説明する。本実施形態において、情報提供サーバ２０は、第１比較処理によって複数の移動端末の中から同一組として検索される可能性の高い識別情報同士を予め関係付けて記憶しておく。そして、新規で受信した位置情報を発した移動端末と同一組になる移動端末の識別情報を、予め関係付けられた識別情報の中から選択する。このように、新規の位置情報を受信する事前に、同一組になる移動端末の識別情報の候補を限定するので、その後の検索処理にかかる時間を軽減することができる。 Here, the effect of this embodiment will be described. In this embodiment, the information providing server 20 associates and stores in advance identification information that is highly likely to be searched as the same set from a plurality of mobile terminals by the first comparison process. And the identification information of the mobile terminal which becomes the same group as the mobile terminal which issued the newly received position information is selected from the identification information associated in advance. In this way, since the candidates for identification information of mobile terminals that are in the same set are limited in advance before receiving new location information, the time required for subsequent search processing can be reduced.
　また、本実施形態においては、同一組になる識別情報の候補を限定する第１比較処理は、各移動端末から受信された位置情報や識別情報等を用いるが、これらの情報を入力する作業を利用者に強いることはなく、利用者としては意識せずとも実現可能な処理である。すなわち、利用者の煩雑な作業が不要である。 In the present embodiment, the first comparison process for limiting the candidates for identification information in the same set uses position information, identification information, and the like received from each mobile terminal. This is a process that does not force the user and can be realized without being conscious of the user. That is, no complicated work for the user is required.
　さらに、本実施形態においては、第１比較処理または第２比較処理の判定基準を複数通り挙げている。これらを適切に組み合わせることによって、同一組の識別情報を検索する確からしさが向上する。 Furthermore, in this embodiment, a plurality of determination criteria for the first comparison process or the second comparison process are listed. By combining these appropriately, the probability of searching for the same set of identification information is improved.
　〔第２の実施形態〕
　図５は、第２の実施形態の情報処理システム２００の構成を示すブロック図である。図５を参照すると、第２の実施の形態は、利用者が携行する複数の移動端末３１、３２、及び３３と、移動端末３１、３２、及び３３を介して利用者に情報提供を行う情報提供サーバ４０とから構成されている。情報提供サーバ４０（情報処理装置）は、受信部２１と、移動履歴記憶部２２と、相互関係抽出部２３と、相互関係記憶部２４と、同一組検索部２５と、コンテンツ送信部２６と、同期要求部４１と、を含む。なお、第１の実施形態の情報提供サーバ２０と、情報提供サーバ４０との違いは、同期要求部４１を追加したことにある。その他の構成要素に関しては、第１の実施形態で説明した内容とほぼ同じなので、ここでの詳細な説明は割愛する。 [Second Embodiment]
FIG. 5 is a block diagram illustrating a configuration of the information processing system 200 according to the second embodiment. Referring to FIG. 5, in the second embodiment, a plurality of mobile terminals 31, 32, and 33 carried by the user, and information that provides information to the user via the mobile terminals 31, 32, and 33. And a providing server 40. The information providing server 40 (information processing device) includes a receiving unit 21, a movement history storage unit 22, a correlation extraction unit 23, a correlation storage unit 24, the same set search unit 25, a content transmission unit 26, A synchronization request unit 41. The difference between the information providing server 20 of the first embodiment and the information providing server 40 is that a synchronization request unit 41 is added. The other components are substantially the same as those described in the first embodiment, and thus detailed description thereof is omitted here.
　移動端末３１、３２、及び３３は、自機の位置を測位する測位処理を間欠的に実行し、測位処理によって生成された位置情報を、情報提供サーバ４０に送信する。また、同期要求部４１は、新規の識別情報と、同一組検索部２５によって出力された識別情報が示す移動端末とのそれぞれに対して（移動端末３１、３２及び３３のうち少なくとも二つに対して）、測位処理を同期させる同期要求信号を送信する。ここで、同期要求信号は、例えば、次回以降の測位処理を行う時刻を指令する信号であり、複数の移動端末に対して同一の時刻を指定することによって、測位処理の同期を実現することができる。移動端末３１、３２、及び３３は、同期要求信号を受信したとき、指定された時刻に測位処理を実行する。 The mobile terminals 31, 32, and 33 intermittently execute a positioning process for positioning the position of the mobile terminal, and transmit the position information generated by the positioning process to the information providing server 40. In addition, the synchronization requesting unit 41 responds to each of the new identification information and the mobile terminal indicated by the identification information output by the same set search unit 25 (for at least two of the mobile terminals 31, 32, and 33). A synchronization request signal for synchronizing the positioning process. Here, the synchronization request signal is, for example, a signal for instructing the time for performing the positioning process after the next time, and the synchronization of the positioning process can be realized by designating the same time for a plurality of mobile terminals. it can. When receiving the synchronization request signal, the mobile terminals 31, 32, and 33 execute the positioning process at a designated time.
