Description

The present invention relates to an information distribution server for distributing distribution information to the mobile communication terminal, relates to information distribution systems and information distribution method.

Services for distributing useful information to users of mobile communication terminals are widely spread to mobile communication terminals such as mobile phones. Among them, a position-dependent service that determines information to be distributed using the current position information of the user is often used. For example, the position information of a user is specified using sensor information such as GPS (Global Positioning System) or information on a base station wirelessly accessed by a mobile communication terminal, and information that is highly likely to be needed at the specified location. The user's convenience is improved by selecting and presenting (for example, refer to Non-Patent Documents 1 and 2). In addition to location information such as GPS, for example, in Patent Document 1, a traffic route is determined from information related to movement by a commuter pass, and information on bases that can be used when using the traffic route (advertising etc.) ) Is acquired and transmitted to the user's terminal. Patent Document 2 proposes a system in which an action pattern is extracted in advance from a user's action history and information to be distributed is determined based on the action pattern in addition to position information.
Japanese Patent No. 3372935 JP 2002-342367 A K. Takahashi, N. Miura, S. Yokoji and K. Shima, “Mobile Info Search: Information Integration for Location-Aware Computing”, IPSJ Journal, Vol. 41, No. 4 pp1192-1201, 2000 Satoshi Oyama, Satoshi Hiramatsu, Koichi Yamada, “Digital City Kyoto: Toward Public Information Space for Citizens”, bit, Vol.33, No.4, pp.8-12, 2001

  However, as described in Non-Patent Documents 1 and 2 and Patent Document 1, the method for determining information to be distributed based only on position information distributes appropriate information according to the user's behavior and purpose. I can't. For example, although the user has just passed near a certain store, the advertisement information of the product in the store may be distributed even though the user is not interested.

  As described in Patent Document 2, if the information to be distributed is determined in consideration of the user's behavior, the above problem is solved. However, even if the behavior is the same at the same place, the purpose of the behavior is generally different for each individual. Therefore, even if information to be distributed is determined in consideration of behavior, appropriate information may not be distributed. For example, despite going to a bookstore to purchase a Christmas present, there arises a problem that information on advertisements that are not suitable for the present is distributed.

The present invention has been made to solve the above problems, an information distribution server which can perform an appropriate information delivery depending on the purpose and higher user behavior, information distribution system and an information distribution method The purpose is to provide.

  Hereinafter, preferred embodiments of an information distribution server, a mobile communication terminal, an information distribution system, and an information distribution method according to the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 shows a configuration of an information distribution system 1 according to the present embodiment. As shown in FIG. 1, the information distribution system 1 includes an information distribution server 10 and a mobile communication terminal 20. The information distribution server 10 and the mobile communication terminal 20 can transmit / receive information to / from each other by mobile communication. Although only one mobile communication terminal 20 is shown in FIG. 1, the information distribution system 1 usually includes an infinite number of mobile communication terminals 20. The information distribution system 1 is a system in which the information distribution server 10 distributes information (distribution information) to the mobile communication terminal 20. The distribution information is usually useful for the user of the mobile communication terminal 20. Specifically, for example, it is information on advertisements for products that the user is interested in.

  FIG. 2 shows a hardware configuration of the information distribution server 10. As shown in FIG. 2, the information distribution server 10 is a data transmission / reception device such as a central processing unit (CPU) 101, a random access memory (RAM) 102 and a read only memory (ROM) 103, which are main storage devices, and a network card. Hardware such as a communication module 104, an auxiliary storage device 105 such as a hard disk, an input device 106 for inputting information to the information distribution server 10 such as a keyboard, and an output device 107 for outputting information such as a monitor It is comprised as a computer provided with. The functions described later of the information distribution server 10 are exhibited by the operation of these components.

  FIG. 3 shows a hardware configuration of the mobile communication terminal 20. As shown in FIG. 3, the mobile communication terminal 20 includes hardware such as a CPU 201, a RAM 202, a ROM 203, an operation unit 204, a wireless communication unit 205, a display 206, and an antenna 207. When these components operate, each function of the mobile communication terminal 20 described below is exhibited.

  Subsequently, functions of the information distribution server 10 and the mobile communication terminal 20 will be described. As shown in FIG. 1, the information distribution server 10 includes a task model database 11, a distribution information database 12, an action schedule information database 13, an action schedule information registration unit 14, a position information reception unit 15, and an effective task determination unit. 16, a distribution information acquisition unit 17, and a distribution information transmission unit 18.

  The task model database 11 is a database in which action information that specifies user actions is hierarchized and stored in association with position information that specifies positions where the actions are performed. Specifically, user behavior information is managed as a “task” and modeled as a task model. Note that this task model database 11 is not a database that specifies the actions of individual users, but is a database that models actions that users can take. Specifically, the task model database 11 holds a task model management table 11a and an event management table 11b, and holds information by storing data in these tables.

  FIG. 4 shows the task model management table 11a. As shown in FIG. 4, in the task model management table 11a, “task ID”, “task name”, “parent task ID”, “metatask flag”, “reference metatask ID”, and “location information” are recorded as one record. Are stored in association with each other. “Task ID” is an ID for uniquely identifying a task, and is composed of a character string of several characters. The “task name” is information indicating specific contents of a task such as “buy a book” or “move to a bookstore”. The “parent task ID” is a “task ID” that identifies the parent task of the task, and is information that forms a hierarchical structure of tasks. A parent task is a higher-order task. From the perspective of the parent task, the task becomes a subtask. For example, a task such as “move to a bookstore” or “select a book to purchase” refers to “1001” as a “parent task ID”, and is a subtask of a reference destination task “buy book”. Show. Note that this information is not stored when there is no parent task.

  The “metatask flag” is information indicating whether or not the task is a metatask. If it is a metatask, it is “True”, and if it is not a metatask, it is “False”. The metatask will be described later. The “reference metatask ID” is a “task ID” that identifies a metatask related to the task. This information is not stored if there is no associated metatask. “Position information” is information indicating a position where the task should be performed. This information is not stored for tasks whose location is not specified.

  Tasks are managed with the above data structure. The tasks included here have three types of tasks. The first is a task associated with specific position information. In the task model management table 11a shown in FIG. 4, a task to which “position information” such as “task ID” “1002”, “1003”, etc. is assigned. A task defined in association with such “position information” is called a “primitive task”. The second corresponds to a complex task defined as a set of a plurality of “primitive tasks”. A task referred to from a plurality of subtasks such as “buy a book” in the task model management table 11a shown in FIG. This type of task is called a “composite task”. Whether or not a certain task is a composite task or a primitive task can be identified by whether or not “position information” is given.

  The third corresponds to a task that expresses a subjective meaning such as an action purpose of a task expressed by a primitive task or a composite task. In the task model management table 11a shown in FIG. 4, tasks having “task IDs” such as “1006” and “1007” correspond to this. Such a task is a “metatask”. The metatask is a task for expressing an action purpose, and is associated with a task that does not include an action purpose such as “buy a book” by the above-mentioned “reference metatask ID”. The metatask indicates, for example, that a specific action for the action purpose of “buying a Christmas present” may be achieved by an action of “buying a book”. As described above, the metatask can be distinguished from other tasks by the “metatask flag”. Metatasks can also be described as a hierarchical task structure by describing a reference relationship using a “parent task ID”. These data are input in advance by, for example, an administrator of the information distribution server 10 when information distribution is performed to the mobile communication terminal 20.

  FIG. 5 shows the event management table 11b. The event managed by the event management table 11b is an object of the user's action, for example, a motive when the user visits a specific facility (shopping center or the like). For example, “Christmas”, “year-end”, “birthday”, and the like. The information distribution system 1 according to the present embodiment enables more convenient information distribution using the concept of an event. As shown in FIG. 5, in the event management table 11b, data of “event ID”, “event name”, and “related task ID” are stored as one record in association with each other. “Event ID” is an ID for uniquely identifying an event, and is composed of a character string of several characters. The “event name” is information indicating the specific content of a task such as “Christmas” or “New Year's holiday”, for example. The “related task ID” is a “task ID” that identifies a task related to the event. This task is stored in the task model management table 11a. As shown in FIG. 5, the “related task ID” can hold a plurality of “task IDs”. These data are input in advance by, for example, an administrator of the information distribution server 10 when information distribution is performed to the mobile communication terminal 20.

  The distribution information database 12 is a database that holds distribution information distributed to the mobile communication terminal 20 in association with any of the tasks that are behavior information held in the task model database 11. Specifically, the distribution information database 12 holds a distribution information management table 12a, and holds information by storing data in this table.

  FIG. 6 shows the distribution information management table 12a. As shown in FIG. 6, in the distribution information management table 12a, data of “distribution information ID”, “name”, “content”, and “target task ID” are stored in association with each other as one record. The “distribution information ID” is an ID for uniquely identifying the distribution information, and is composed of a character string of several characters. “Name” and “content” are distribution information distributed to the mobile communication terminal 20. The “target task ID” is a “task ID” that identifies a task that triggers distribution of the distribution information. This task is stored in the task model management table 11a. More details will be described in the distribution process. These data are input in advance by, for example, an administrator of the information distribution server 10 when information distribution is performed to the mobile communication terminal 20.

  The action schedule information database 13 is associated with information for specifying the mobile communication terminal 20, and any of the tasks which are action information held in the task model database 11 as action schedule information for specifying the action schedule of the user of the mobile communication terminal 20. It is a database that holds Specifically, the action schedule information database 13 holds an action schedule information management table 13a, and holds information by storing data in this table.

  As shown in FIG. 7, in the action schedule information management table 13a, data of “terminal ID”, “behavior scheduled task ID”, and “task log series” are stored in association with each other as one record. The “terminal ID” is an ID for uniquely identifying the mobile communication terminal 20 and is composed of a character string of several characters. As the “terminal ID”, each mobile communication terminal 20 corresponding to its own terminal is stored. “Behavior scheduled task ID” is a “task ID” that identifies a task as the user's scheduled behavior information. This task is stored in the task model management table 11a. The “task log series” is a “task ID” of a task that is determined to be actually performed. As shown in FIG. 5, the “task log series” can hold a plurality of “task IDs”. These data are registered in advance from the mobile communication terminal 20 when information distribution is performed, as will be described later. However, these data need not be registered from other than the mobile communication terminal 20, and may be registered by, for example, an administrator of the information distribution server 10.

  The action schedule information registration unit 14 is an action schedule information registration unit that receives a registration request from the mobile communication terminal 20 and registers the action schedule information of the mobile communication terminal 20 in the action schedule information database 13. The process of registering the action schedule information by the action schedule information registration unit 14 will be described in detail later.

  The position information receiving unit 15 is a position information receiving unit that receives position information of the mobile communication terminal 20 from the mobile communication terminal 20. The position information receiving unit 15 notifies the valid task determining unit of the received position information.

  The valid task determination unit 16 is a user behavior specifying unit that specifies the user's behavior with reference to the task model database 11 from the location information of the mobile communication terminal 20 received by the location information receiving unit 15. Details of how to specify will be described later in detail. Here, the user's action is specified by specifying a task. The valid task determination unit 16 outputs information regarding the identified task to the distribution information acquisition unit 17.

  The distribution information acquisition unit 17 determines the distribution information to be distributed from the task model database according to the user action specified by the effective task determination unit 16 and the user action schedule information held in the action schedule information database 13. It is a distribution information acquisition means to acquire. The distribution information acquisition unit 17 outputs the acquired distribution information to the distribution information transmission unit 18.

  The distribution information transmitting unit 18 is a distribution information transmitting unit that distributes the distribution information acquired by the distribution information acquiring unit 17 to the mobile communication terminal 20. The distribution information is distributed by transmitting the distribution information to the mobile communication terminal 20 by mobile communication. This completes the description of the function of the information distribution server 10.

  Next, functions of the mobile communication terminal 20 will be described. As shown in FIG. 1, the mobile communication terminal 20 includes a task model display unit 21, an event designation unit 22, an action scheduled task designation unit 23, a task log display unit 24, a position measurement unit 25, and a position information notification unit. 26 and a distribution information display unit 27. Here, the task model display unit 21, the event specifying unit 22, the scheduled action task specifying unit 23, and the task log display unit 24 are components for registering the scheduled action information for specifying the action schedule of the user in the information distribution server 10. It is. The position measurement unit 25, the position information notification unit 26, and the distribution information display unit 27 are components for receiving information distribution.

  The task model display unit 21 is an action schedule information receiving unit that receives and displays a plurality of action information transmitted from the information distribution server 10 as action schedule information candidates for specifying the action schedule of the user of the terminal 20 itself. is there. This reception and display are performed during a user action schedule registration process performed between the mobile communication terminal 20 and the information distribution server 10. The transmission of a plurality of behavior information from the information distribution server 10 is performed, for example, triggered by a request for starting a registration process of a behavior schedule from the mobile communication terminal 20 to the information distribution server 10 by a user operation or the like. The behavior information is displayed as shown in FIGS. 8 and 9, for example. The display contents and processing will be described later in more detail.

  The event designating unit 22 is means for receiving an input designating event information from the user based on the display in the task model display unit 21 and transmitting the input to the information distribution server 10. The action schedule task designation unit 23 receives an input for designating action schedule information from the user based on the display in the task model display unit 21, and transmits it to the information distribution server 10. That is, the action schedule task specifying unit 23 receives the input of the action schedule information for specifying the action schedule of the user and transmits the action schedule information to the information distribution server 10 according to the output of the plurality of action information by the task model display unit 21. Information transmission means. More specifically, these will be described later.

  The task log display unit 24 is an additional information output unit that receives and outputs additional information generated from the action schedule information of the user of another mobile communication terminal 20 from the information distribution server 10. This information is referred to by the user during the action schedule information registration process. More specifically, it will be described later.

  The position measurement unit 25 is a position measurement unit that measures the position of the terminal 20 and generates position information. For the position measurement, for example, a positioning system using an RF-ID (Radio Frequency Identification) tag can be used. This positioning system communicates between an RF-ID tag installed on the environment side and an RF-ID reader provided in the mobile communication terminal 20, and acquires an area code indicating a position from the RF-ID tag. Thus, the position can be measured. This area code corresponds to the position information stored in the task model management table 11a. The area code is expressed by a symbol such as “Loc (00000)”. Note that the numbers included in parentheses indicate specific areas, and each area is uniquely identified by a unique number string. Positioning by the position measuring unit 25 is executed at regular intervals. For positioning, other than the above method, for example, GPS (Global Positioning System) can be used. However, since positioning with GPS is difficult indoors, it is preferable to use the positioning system using the RF-ID tag when assuming indoor information distribution. The location information of the terminal 20 is output to the location information notification unit 26.

  The position information notification unit 26 is a position information notification unit that transmits the position information of the terminal 20 acquired by the position measurement unit 25 to the information distribution server 10 together with the terminal ID that identifies the terminal 20 in order to receive the information distribution. is there. The terminal ID is stored in advance in the mobile communication terminal 20. This transmission is performed with the input of the position information of the terminal 20 from the position measurement unit 25 as a trigger.

  The distribution information display unit 27 is a distribution information output unit that receives and displays distribution information transmitted from the information distribution server 10 in response to the transmission of the position information from the position information notification unit 26. The output of the distribution information is displayed, for example, as characters or images on a display included in the mobile communication terminal 20 so that the user can refer to it. Even if the position information is transmitted, the distribution information may not be transmitted from the information distribution server 10. This completes the description of the function of the mobile communication terminal 20.

  Subsequently, processing (information distribution method) executed in the information distribution system 1 of the present embodiment will be described using the flowcharts of FIGS. In the information distribution system 1, a process of registering action schedule information for specifying a user's action schedule is performed from the mobile communication terminal 20 to the information distribution server 10 before information distribution is performed. First, the registration process will be described with reference to the flowchart of FIG.

  First, the mobile communication terminal 20 transmits a request to start the action schedule information registration process to the information distribution server 10. This transmission is performed using a user operation as a trigger. This request includes the terminal ID of the mobile communication terminal 20 so that the mobile communication terminal 20 can identify the transmission. In the information distribution server 10, when the action schedule information registration unit 14 receives a request to start this process, the process is started (S01).

  Subsequently, a list of event information is read from the event management table 11 b of the task model database 11 by the action schedule information registration unit 14. Specifically, information of “event ID” stored in the event management table 11b and “event name” corresponding to the event ID is read out as a list. The read event information is transmitted to the mobile communication terminal 20 by the action schedule information registration unit 14 (S02). In the mobile communication terminal 20, the transmitted event information is received and displayed by the task model display unit 21. As shown in FIG. 8, the event information is displayed in a list format so that the “event name” is referred to by the user. Further, this display is performed so that the user can designate any event.

  Subsequently, in the mobile communication terminal 20, an event is selected from the list by the user. In this selection, as described above, what becomes the purpose of the user's action, for example, what motivates the user when visiting a specific facility (shopping center or the like) is selected. For example, “Birthday” is selected if the purpose is “Purchase of a birthday present”, and “Christmas” is selected if it is “Preparation for a Christmas party”. Here, when the user's purpose is not included in the list or when there is no specific purpose, the selection of the event can be omitted. When the event selection is omitted, an item “N / A” is provided in the list displayed as shown in FIG. 8, or a button such as “Omit event selection” is displayed. It can be realized by making it selectable. The user selection input is accepted by the event designating unit 22, and an event ID corresponding to the event is transmitted to the information distribution server 10. At this time, the terminal ID of the mobile communication terminal 20 is given to the transmitted event ID so that it can be identified from which mobile communication terminal 20 the transmission is made. In addition, when the selection of an event is omitted, information to that effect is transmitted, and the information distribution server 10 can recognize that fact.

  In the information distribution server 10, the transmitted information is received by the action schedule information registration unit 14. Subsequently, the action schedule information registration unit 14 determines whether an event is designated based on the information (S03). This determination is made based on, for example, whether the received information includes a valid event ID.

  When an event is specified, the event ID of the event is received by the action schedule information registration unit 14 (S04). Subsequently, the action schedule information registration unit 14 reads out information on the task related to the event ID from the task model management table 11 a of the task model database 11. The task related to the received event ID is read with reference to the related task ID information in the event management table 11b. Information of a task having a task ID that matches the related task ID is read from the task model management table 11a. Specifically, information of “task ID” stored in the task model management table 11a and “task name” corresponding thereto is read (S05, action schedule information registration step). Reading of task information is performed not only for tasks directly related as related task IDs in the event management table 11b, but also for information on tasks that have a parent-child relationship with the task.

  On the other hand, if it is determined by the above-described determination by the action schedule information registering unit 14 that no event is specified, information on tasks for which “metatask flag” is set to “True” among information on all tasks is displayed. Are read from the task model management table 11a (S06, action schedule information registration step).

  The read task information is transmitted to the mobile communication terminal 20 by the action schedule information registration unit 14 as a candidate for the action schedule information of the user of the mobile communication terminal 20 (S07, action schedule information registration step). In the mobile communication terminal 20, the transmitted task information is received and displayed by the task model display unit 21. As shown in FIG. 9, the task information is displayed in a list format so that the user can refer to the “task name” and the parent-child relationship between tasks. For example, in the task model management table 11a shown in FIG. 1, a task “preparing a Christmas present” with a task ID “1006” is indicated by a task ID “1007”, “1008”, and “1009”, respectively. Since these tasks are referred to by the “parent task ID” from the tasks “buy Christmas gifts”, “wrapping Christmas gifts”, and “send Christmas gifts”, these three tasks are higher-order tasks as shown in FIG. Shown to be a subtask of “Preparing Christmas Gifts”. This display is performed so that the user can designate any task as the user's action schedule information.

  Subsequently, in the mobile communication terminal 20, a task is selected from the list by the user. In this selection, as described above, a user's action schedule is selected. When selecting a task, it is not necessary to select a task at the end, and a task higher in the hierarchy may be selected. The user's selection input is accepted by the scheduled action task specifying unit 23, and a task ID corresponding to the task is transmitted to the information distribution server 10 as a registration request. At this time, the terminal ID of the mobile communication terminal 20 is given to the transmitted task ID so that it can be identified from which mobile communication terminal 20 the transmission is made. In the task selection, only one task may be selected, or a plurality of tasks may be selected.

  When a task ID registration request is made (S08, action schedule information registration step), the information distribution server 10 receives the terminal ID and the task ID corresponding to the terminal ID by the action schedule information registration unit 14 (S09). , S10, action schedule information registration step). When the terminal ID and the task ID are received, they are stored in the action schedule information management table 13a of the action schedule information database 13 shown in FIG. 7 by the action schedule information registration unit 14 (S11, action schedule information registration step). . For example, when the received terminal ID is “001” and the task ID is “1006”, the data in the first row of the action schedule information management table 13a shown in FIG. 7 is registered. The above is the process of registering the action schedule information that identifies the action schedule of the user.

  Subsequently, information distribution processing performed based on the registered action schedule information will be described with reference to the flowcharts of FIGS.

  First, in the mobile communication terminal 20, the position measurement unit 25 measures the position of the terminal 20 itself. The position is measured periodically at regular intervals as described above, for example. The measured position information is output to the position information notification unit 26 and transmitted to the information distribution server 10 by the position information notification unit 26. The terminal ID of the mobile communication terminal 20 is added to the transmitted position information.

  In the information distribution server 10, the position information receiving unit 15 receives the position information transmitted from the mobile communication terminal 20 (S31, position information receiving step). Further, the terminal ID added to the received position information is acquired by the position information receiving unit (S32, position information receiving step). The acquired position information and terminal ID are output to the effective task determination unit 16.

  In the effective task determination unit 16, the action of the user of the mobile communication terminal 20 is specified from the acquired position information (S33, user action specifying step). The user's action is specified by determining the effectiveness of the task. The validity of the task is determined by whether or not a specific task is associated with the position information transmitted from the mobile communication terminal 20. Specifically, in the task model management table 11 a of the task model database 11, it is determined as “valid” when there is a task having position information transmitted from the mobile communication terminal 20, and “invalid” when it does not exist. It is determined (S34, user action specifying step). If the valid task determination unit 16 determines “valid”, the task is notified to the distribution information acquisition unit 17. If it is determined as “valid”, the task ID of the task is stored in the “task log series” column for the mobile communication terminal 20 in the action schedule information management table 13a (S35). The “task log series” holds the series information of tasks determined to have been actually performed as described above. If the valid task determination unit 16 determines “invalid”, the information distribution is not performed and the process ends.

  Subsequently, distribution information to be distributed to the mobile communication terminal 20 is acquired by the distribution information acquisition unit 17. The acquired distribution information corresponds to the user task specified above and the task that is the user's action schedule, respectively. Specifically, the distribution information is acquired as follows. First, distribution information as candidates for the acquired distribution information is read from the distribution information management table 12a (S36, distribution information acquisition step). Subsequently, it is determined whether or not each read distribution information is acquired as distribution information to be distributed (S37, distribution information acquisition step). This determination process will be described with reference to the flowchart of FIG.

  First, it is determined whether or not the target task of the distribution information to be determined is a metatask (S37a, distribution information acquisition step). This determination is made with reference to the “metatask flag” information of the task corresponding to the “target task ID” of the distribution information in the task model management table 11a. If the “metatask flag” is “True”, it is determined that the target task is a metatask.

  For example, it is determined that the target task of the distribution information is not a metatask so that the task ID of the target task is “1001” (distribution information corresponding to the distribution information ID “003” in the distribution information management table 12a of FIG. 6). In the case (see the task model management table 11a in FIG. 4), it is determined whether or not the target task is a composite task (S37b, distribution information acquisition step). This determination is made based on whether the task ID of the target task is held as the “parent task ID” of another task. For example, if the task ID of the target task is “1001”, the “parent task ID” of the tasks with the task IDs “1002”, “1003”, “1004”, and “1005” is “1001”. It is judged that. When it is determined that the target task is a composite task, the task is converted into a set of primitive tasks having the composite task as a parent task (S37c, distribution information acquisition step). That is, for the task “Buy Book” with the task ID “1001”, the subtask is “Move to Bookstore” with the task IDs “1002,” “1003,” “1004,” and “1005,” respectively. , “Select a book to purchase”, “Move to cash register”, and “Pay for purchase” task set. Subsequently, it is determined whether or not the task ID of the task identified in this way matches the task ID of the “task log series” related to the mobile communication terminal 20 (S37d, distribution information acquisition step). For example, as shown in FIG. 7, it is determined that the mobile communication terminals 20 whose terminal IDs are “003” and “004” match. Here, the condition for determining whether or not all subtasks are included in the task log series is a condition for determining the coincidence. However, there are various determination conditions, for example, it may be determined that even partial matches are matched, and it is not determined that they are not included unless they are all included and do not match the order of appearance. Rules may be set.

  When it is determined in the above determination (S37b) that the target task is not a composite task, it is determined whether the task ID of the target task matches the task ID of the “task log series” (S37d, distribution information acquisition step).

  If the task ID of the task identified from the target task and the task ID of the “task log series” do not match (S37e, distribution information acquisition step), it is determined that there is no distribution information distributed to the mobile communication terminal 20. The process is terminated. When the task ID of the task specified from the target task matches the task ID of the “task log series” (S37e, distribution information acquisition step), the distribution information is determined as distribution information to be distributed to the mobile communication terminal 20. (S38f, distribution information acquisition step).

  In the determination (S37a), for example, the task ID of the target task is such that the task ID of the target task is “1007” (distribution information corresponding to the distribution information ID “002” in the distribution information management table 12a of FIG. 6). Is determined to be a metatask, a task that refers to the metatask is specified (S37g). This specification is performed by referring to the reference metatask ID of the task corresponding to the target task in the task model management table 11a. For example, if the task ID of the target task is “1007”, the task “buy book” with the task ID “1001” having the reference metatask ID “1007” is identified as a task that refers to the metatask.

  Subsequently, it is determined whether or not the identified task is a composite task, and if it is determined that it is a composite task, it is converted into a set of primitive tasks having the composite task as a parent task in the same manner as in (S37c). (S37h, distribution information acquisition step). Subsequently, matching with the task log series is performed for those tasks in the same manner as (S37d) (S37i, distribution information acquisition step). If the task ID of the task identified or converted from the target task does not match the task ID of the “task log series” (S37j, distribution information acquisition step), there is no distribution information distributed to the mobile communication terminal 20. A determination is made and the process is terminated.

  When the task ID of the task identified from the target task and the task ID of the “task log series” match (S37j, distribution information acquisition step), the task ID of the target task and the information distribution target (location information) It is determined whether or not the action scheduled task ID related to the mobile communication terminal 20 that has been transmitted matches (S37k, distribution information acquisition step). The action schedule task ID related to the mobile communication terminal 20 can be acquired by referring to the action schedule information management table 13a using the terminal ID as a key. For example, if the task ID of the target task is “1007” and the terminal ID is “003”, the scheduled task ID is “1007”, so the task ID of the target task and the scheduled task ID match. . Here, an example is shown in which the task ID of the target task and the scheduled action task ID are completely the same, but in the matching of the scheduled action task ID and the target task ID, the task with the scheduled action task ID is specified as the upper task. Even if it is present (for example, a task with a task ID of “1006”), it is determined that they match.

  If the task ID of the target task matches the scheduled action task ID, the distribution information is determined as distribution information to be distributed to the mobile communication terminal 20 (S37f, distribution information acquisition step). If the task ID of the target task and the scheduled action task ID do not match, it is determined that there is no distribution information distributed to the mobile communication terminal 20, and the process is terminated. As described above, each read distribution information is determined as distribution information to be distributed, and it is determined whether or not it is acquired.

  The “content” of the determined distribution information is acquired from the distribution information management table 12 a by the distribution information acquisition unit 17 and output to the distribution information transmission unit 18. The output distribution information is transmitted to the mobile communication terminal 20 by the distribution information transmission unit 18 (S38, distribution information transmission step). In the mobile communication terminal 20, the distribution information transmitted from the information distribution server 10 in response to the transmission of the position information is received and output by the distribution information display unit 27.

  As described above, according to the present embodiment, since the distribution information transmitted based on the user behavior that is hierarchized is acquired, according to the user's upper behavior in the hierarchization, that is, the purpose of the user, Appropriate information distribution can be performed. For the user, it is possible to receive appropriate information distribution according to the purpose. In addition, for information providers, it becomes possible to perform information distribution for the subjective behavioral purpose of each user, increasing information distribution opportunities and providing various services according to the individual user's behavioral purpose. Can be induced.

  Further, since the action schedule information can be registered from the mobile communication terminal 20 as in this embodiment, the action schedule information database can be easily constructed, and the highly convenient information distribution system 1 can be realized. .

  If the action schedule information candidates are transmitted from the information distribution server 10 to the mobile communication terminal 20 and the action schedule information is registered based on the candidates, the action schedule information can be easily transmitted from the mobile communication terminal 20. The information distribution system 1 with higher convenience can be realized. Further, as in the present embodiment, if the event is first designated and the action plan information candidates narrowed down based on the event are transmitted from the information distribution server 10, the action schedule information is further transmitted. It can be done easily. Thereby, even if it is the mobile communication terminal 20 with which a screen is small and it is difficult to input information, action schedule information can be registered easily.

  Note that the information distribution system 1 may be modified as follows for the purpose of further improving convenience. In the embodiment described above, the information transmitted from the information distribution server 10 to the mobile communication terminal 20 at the time of registration of the action schedule information is event information and action information. In addition to these, the action schedule information registration unit 14 of the information distribution server 10 generates a plurality of additional information generated from the action schedule information of the user of another mobile communication terminal 20 held in the action schedule information database 13. It is good also as transmitting to the mobile communication terminal 20 in addition to action information. For example, when the task ID of the task “Purchase Christmas gift” is transmitted as the action schedule information from the mobile communication terminal 20, for example, the action schedule information registration unit 14 sets the task “Purchase Christmas gift” as the action schedule information. The other user's task log is transmitted to the mobile communication terminal 20 in a ranking format or the like.

  Other users' task logs are in the form of ranking, etc., from the action schedule information management table 13a, the data from the “task log series” of the user of the mobile communication terminal 20 with the “purchase Christmas gift” task as action schedule information. It can be done by acquiring. In the mobile communication terminal 20, the task log display unit 24 displays and outputs the information thus transmitted from the information distribution server 10 so that the user can refer to it. At this time, various forms can be considered as an actual display method. For example, there are display methods such as “Many people who have input the same purpose are“ purchasing books ””. It is also possible to display a plurality of task candidates (such as “buy book”, “wrapping service”, “buy umbrella”) together with a map on the screen and present it as an action plan.

  When the user moves to a specific position, the information distribution server 10 determines a task from the task model management table 11a, and refers to the “scheduled task ID” of the user who executed the next determined task. Meta-tasks can be presented. For example, when the task “buy book” can be determined from the transition information of the user's position, the user who matches the same task “buy book” is selected from the “task log series” of other users. Then, metatasks that many of these users have pre-registered can be presented. There are various forms of information to be presented. For example, there is information that promotes the willingness to purchase such as "Many customers are purchasing products for" Christmas gifts "here".

  In this way, by using the action schedule information database 13 that records the correspondence between the user's action purpose and the user's action determined using the location information as a log, the user who has acted with a specific action purpose It is possible to show how other users who acted with the same behavior purpose actually performed. This makes it possible to recommend an action plan according to the purpose. Similarly, by using the action schedule information database 13 to present a purpose of action that can be achieved in this area to a user who has visited a specific area, the motivation of the action that the user did not recognize at the beginning is given. be able to.
