Description

[Technical field]

[0001] The present invention relates to a message delivery system for delivering a predetermined message to a user's terminal, and more particularly to a message delivery system capable of carefully selecting and delivering messages to be sent to mobile terminals mounted on vehicles traveling on roads based on location information and the like, and capable of changing the message to be delivered depending on the user. [Background technology]

[0002] Several message delivery systems for delivering a predetermined message to the terminals of users staying in a certain area (also called a geofence) have been considered (see, for example, Patent Documents 1 and 2). These systems can acquire the current location using a means for acquiring location information of the terminal, and deliver a message associated with the area to the terminal. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2009-169500 ​​A [Patent Document 2] JP 2019-36897 A Summary of the Invention [Problem to be solved by the invention]

[0004] Patent Document 1 outputs advertisements to user terminals moving along a specific route such as an arbitrarily set road, etc. Also, it has an advertisement bidding function, and can calculate the travel time of the route and output advertisements according to that time. Patent Document 2 discloses a method for setting a non-circular partitioned area as a geofence, and for providing a predetermined service such as sending useful information to a user to a terminal that is within the geofence.

[0005] On the other hand, in Patent Document 1, advertisements according to the travel route can be output, but all advertisements included in the travel route are targeted, including advertisements that are in the opposite direction to the travel direction and do not need to be viewed because they have already passed. In addition, Patent Document 2 can determine more complex areas, but cannot exclude information within the area that is not intended to be visited. Furthermore, Patent Documents 1 and 2 do not consider providing different information to each registered user, such as information for general users and information for in-company business use. To provide a message system capable of carefully selecting and delivering messages to terminals moving within a route based on location information, etc., and capable of changing the messages to be delivered depending on the user. [Means for solving the problem]

[0006] The present invention is as follows. 1. A message delivery system for transmitting notification information appropriate for a specific area to a user terminal moving within the area, Each of the regions is determined based on a reference point, a transmission information database for storing transmission information including a set of the notification information to be transmitted, destination area information indicating the moving direction and area of ​​the user terminal, and transmission management identification information for identifying a sender; determining the area from location information received from the user terminal; determining a moving direction from the position information and previous position information obtained before the position information; a notification information transmitting means for referring to a transmission information database for the transmission destination area information consisting of the determined area and the determined moving direction, and the transmission management identification information included in the transmission information that matches the transmission destination area information, and transmitting the notification information included in the transmission information obtained to the user terminal; two or more transmission information management means for registering the transmission information to be transmitted from a registration terminal in a registration management database; A message delivery system comprising: the sender, and two or more sender management means for limiting the transmission information management means that the registered terminal can use by using transmission management identification information. 2. The message delivery system according to claim 1, wherein the notification information sending means is capable of sending the notification information when the user terminal enters or exits the area. 3. The user terminal is a communication terminal that moves along with a vehicle traveling on a road, The destination area information of the transmission information includes road reference point information as the area and road movement direction information as the movement direction, The message delivery system described in 2., wherein the notification information sending means obtains the reference point information and the travel direction information of the road from the location information sent from the user terminal, and refers to the transmission information database for which the reference point information and the travel direction information match. 4. A message delivery system as described in claim 3, wherein the reference point is a milepost on the road, and the direction of movement is determined by a change in the reference point that is closest in distance. 5. The message delivery system according to claim 4, wherein each of said transmission information management means is capable of registering in said registrant management database only the transmission information that includes said transmission management identification information that is different from each other. 6. A message delivery system according to claim 5, further comprising a transmission fee calculation means for calculating a usage fee for each of said transmission information management means, said transmission fee calculation means calculating a usage fee by referring to an amount of said notification information transmitted to said user terminal. Effect of the Invention

[0007] According to this message delivery system, the notification information transmission means transmits notification information limited by the direction of movement in addition to the area to the user terminal, so that the terminal user can be provided with accurate information on the destination of the movement, excluding unnecessary notification information. It is expected that the user will take action by utilizing the transmitted information limited to the area. In addition, by providing two or more transmission information management means and sender management means, it is possible to separate the management contents by, for example, changing the notification information to be handled or changing the manager by allocating the transmission information management means and sender management means for each field of notification information, etc. This makes it easy to carry out smooth operation by separating the management contents for each field, etc.

[0008] If the notification information sending means is capable of sending the notification information when the user terminal enters or exits the area, it can send the notification information to be sent without delay upon arrival at or leaving the area. When the destination area information includes road reference point information, it can be used to provide road congestion and danger information and to take detours or to stop at facilities along the road. When the reference points are distance markers on the road and the direction of travel is determined by changes in the reference point that is closest in distance, by utilizing location information that is spaced at regular intervals along the travel route, notification information can be registered without dividing the area into overpopulated and sparsely populated areas, and accurate information according to the location can be provided. When each of the transmission information management means is capable of registering the transmission information in the registrant management database only if the transmission information includes transmission management identification information that is different from one another, the transmission information can be divided by purpose, field, etc. and managed separately. When a transmission fee calculation means is provided for each transmission information management means, the transmission information can be divided into different applications or fields, and the fees can be calculated based on different standards.

[0010] The matters shown herein are illustrative and are intended to exemplify the embodiments of the present invention, and are described for the purpose of providing what is believed to be the most effective and easily understandable explanation of the principles and conceptual features of the present invention. In this respect, it is not intended to show structural details of the present invention beyond the extent necessary for a fundamental understanding of the present invention, and the description in conjunction with the drawings will make it clear to those skilled in the art how some forms of the present invention can be actually embodied.

[0011] The present invention will now be described in detail with reference to the accompanying drawings. This message delivery system is a system for transmitting notification information suited to a specific area to a user terminal moving within said area, and as shown in Fig. 1, comprises a transmission information database 12, a notification information transmitting means 11, a transmission information managing means 13, and a sender managing means 14. In addition, the system may further comprise a transmission fee calculating means 15.

[0012] The predetermined area is one or more areas. The area indicates a certain range of an area that is appropriately set for distributing notification information. The area indicated by this area can be an area within a certain distance from an appropriately set reference point. In addition, multiple areas may be set adjacent to each other, or may be set apart. In addition, the multiple areas that have been set may overlap in part or in whole. A reference point is a point that can represent a point in an area using information about a location such as latitude and longitude. Reference points can be prepared arbitrarily. Furthermore, by using existing location information, data can be reused and the effort of creating the information from scratch can be eliminated. An example of this existing location information is distance markers (also called kilometer posts). Distance markers are signs that indicate the distance from a specific point and are installed at specific intervals on routes such as roads and railways, and are arranged along the route for travel, making them suitable as reference points for an area. In addition, the positions of traffic lights, intersections, and traffic signs can also be used as reference points. The reference point information using various reference points includes information such as the position of the road, and can be determined or obtained from map information of existing public roads, expressways, etc. These reference points can be registered in the reference point database 16 and referred to when calculating the area. A list of position information (for example, position information using latitude and longitude) of each reference point is registered in the reference point database 16. The reference point database 16 is also used to determine whether the user terminal is staying within a specified area by determining the reference point that is closest to the position information received from the user terminal by the notification information transmitting means and that is within the certain range.

[0013] The transmission information database 12 is a database for storing transmission information, and is referred to by the notification information transmitting means. Also, the transmission information is registered by the transmission information management means. The transmission information may include notification information and destination area information. The notification information is information to be notified to the user of the user terminal and is output on the user terminal. The types of notification information include text, images, videos, sounds, URL links, etc., which are delivered by the message delivery system and output on the user terminal, and combinations of these. In addition, the types of notification information are not limited to the above examples, and may include any type, such as control information for an indicator lamp on the user terminal and vibration. The content of the notification information is not particularly limited, and may be, for example, information about a specific area, which is a specific region. Specific examples of the information about the specific region include information dealing with matters occurring in a specific region, such as road traffic regulations, fallen objects, and traffic congestion information, advance notice of the matters, usage guides for road-related facilities (service areas, parking areas, roadside stations, gas stations, car shops, etc.), insurance guides, and tourist information. Furthermore, examples of notification information within a company or organization include points of tour destinations, contact information at tour destinations, and delivery operation information. The notification information can be managed separately by providing a plurality of groups, each group being a field of a predetermined range, and using a transmission information management means corresponding to each group. For example, the notification information can be classified into three fields, namely, road information, road-related facilities, and tourist information, a transmission information management means can be provided for each classification, and the three transmission information management means can be managed independently by different workers. The notification information may further include notification date and time information such as a notification start date and time and a notification end date and time. The notification date and time information is used to determine the period during which the notification information is valid, and notification can be performed only when the current time, the terminal time, etc. are within that period. The notification date and time information may also be a regular period such as the first day of every month, every Monday, or every 12:00.

[0014] As shown in Fig. 2, the destination area information is information indicating a moving direction linked to notification information included in the same transmission information and the specified area targeted by the notification information. The moving direction is the direction in which the user terminal moves within the area. If the movement route of the user terminal is a movement route with few branches such as a highway or a railway line, the moving direction is limited to two directions, an upstream direction and a downstream direction, and the transmission information within the area can be divided into two types. Note that in an area including an intersection or a branch point, three or more directions may be used. The method by which the notification information sending means determines the current moving direction of the user terminal can be selected arbitrarily, and examples include a method of determining the moving direction from location information and old location information determined before the location information, and a method of using directional information determined by an electronic compass provided in the user terminal, etc. When the reference point uses the reference point information of the road, the driving direction information can be used as the moving direction. The driving direction information can be obtained by the change of the closest reference point. The moving direction as the driving direction information is determined by the approach or departure of a pre-stored distance marker (also called a kilometer post). For example, as shown in FIG. 3, if the current position is P1, the nearest distance marker is distance marker B, and the previous nearest distance marker was distance marker C, the moving direction is from distance marker C to distance marker B (left direction in FIG. 3). When the driving direction information is used as the moving direction, the upstream lane and the downstream lane of the road can be distinguished, and information that is valid only for one of the upstream lane or the downstream lane (for example, information on traffic congestion or fallen objects occurring on the upstream lane) can be distinguished from the other lane, and notification information required only for the moving direction of the user terminal can be transmitted to the user terminal.

[0015] The notification information transmitting means is a means for determining an area from location information received from the user terminal, determining a moving direction from the location information and old location information determined before the location information, and referring to a transmission information database for transmission information including the notification information, the moving direction, and destination area information indicating the area to be transmitted, which coincides with the area and the moving direction, to the user terminal.

[0016] The notification information transmitting means receives location information indicating the current location of the user terminal transmitted from the user terminal as appropriate, and acquires notification information from a transmission information database based on the received location information. Specifically, notification information including area information including the location information within an area is acquired from the transmission information database. The notification information transmitting means can transmit the notification information when the user terminal enters or exits the area. The notification information can also be transmitted to the user terminal if the user terminal is staying in the area at the time of registration. For example, when an inquiry is made from the user terminal, the notification information transmitting means can transmit the notification information to the user terminal if the location information is within the area, the notification information is new, and the notification information has not been notified. Furthermore, the notification information transmitting means can set an expiration date for the notification information. Also, the notification information may be transmitted to a user terminal that is present in the area at a predetermined date and time. Examples of the predetermined date and time include a date and time that is appropriately set, as well as a regular period such as the first day of every month, every Monday, or every 12:00.

[0017] Furthermore, the notification information transmitting means can limit the notification information by movement direction information. The movement direction information can store the location information transmitted from the user terminal as history, determine whether the current location is within the area and whether the previous location was within the area, and determine whether the area has been entered or left by combining the determination results. For example, when the current location is within the area and the previous location is outside the area, it is determined that the area has been entered. Also, when the current location is outside the area and the previous location is within the area, it is determined that the area has been moved outside. Also, the reference points of the current location information and the old location information are obtained, respectively, and the moving direction can be determined from the change in distance from each reference point. The old location information is location information obtained before the current location information, and can be, for example, location information previously transmitted by the user terminal. The old location information is not limited to the previous location information, but can be location information from a predetermined time ago, location information immediately before or immediately after entering an area, location information immediately before or immediately after leaving an area, etc. Also, the moving direction can be determined from the direction of movement between two reference points. For example, if the reference point closest to the old location information is A, and the reference point other than A that is closest to the current location information and is closer in distance than the old location information is B, it can be determined that the vehicle is moving toward reference point B. This type of calculation can be performed by the above method when the travel route is limited to one direction, such as on a highway or railway, because the number of destination areas is limited to one and there is no need to consider other areas.

[0018] The user terminal is a communication terminal that can transmit location information obtained by a GPS receiver or the like provided in the terminal to the message delivery system, and can receive and output notification information from a notification information transmitting means. Examples of such a user terminal include a car navigation system (also called a car navigation system), and mobile terminals such as smartphones and tablets. In addition, the user terminal can be a communication terminal that moves along with a vehicle traveling on a road. This message delivery system can be used by installing software for utilizing the notification information transmission means in advance on the terminal, or by running the software on a web browser as appropriate. The user terminal transmits the transmission management identification information to the notification information transmitting means. Furthermore, the notification information transmitted from the notification information transmitting means can be notified by displaying it on a screen, by voice, or the like. The transmission management identification information is information for identifying a plurality of transmission information managing means. One transmission management identification information usually corresponds to one transmission information managing means, but this is not limited thereto, and the system may be provided with transmission management identification information corresponding to a plurality of transmission information managing means. Furthermore, when there is no transmission management identification information, it can also be treated as transmission management identification information corresponding to one or more appropriately set transmission information managing means. When there is no such transmission management identification information, this message delivery system is suitable for use as a public notification information delivery system.

[0019] The transmission information management means may be provided in two or more, and the transmission information transmitted from the registration terminal may be registered in the transmission information database. The registration terminal is a terminal for registering the transmission information to be registered in the transmission information database, and is usually any communication terminal owned by the provider of the transmission information. Examples of this include a mobile terminal similar to the user terminal, a personal computer, etc. In this message delivery system, the registration terminal may use the transmission information management means identified by the transmission management identification information by previously registering software for using the transmission information management means in the registration terminal, or by allowing the registration terminal to use a website for using the transmission information management means on a web browser as appropriate. In addition, the registration terminal may transmit the transmission management identification information input by ID authentication or the like to the transmission information management means. In addition, the notification information, the area to notify the notification information, and the movement direction may be input, and the input notification information, the area, and the movement direction may be transmitted to the transmission information management means.

[0020] Furthermore, each transmission information management means can limit the area that can be registered as transmission information to a part of all areas registered in the reference point database. By limiting the area that can be registered to a part, it is possible to set the area to be managed by each transmission information management means so that the areas where a group of areas are collected do not overlap, or to set a transmission information management means that manages only the area that includes specific facilities such as road-related facilities, and it is easy to manage the transmission information collectively while managing only the area necessary for the purpose. For example, notification information such as road traffic regulations, an administrator who manages workers who handle congestion information, a guide to using road-related facilities, insurance information, and tourist information can be managed separately. Furthermore, information such as a transmission period [examples include every day of the week (every Monday), every month (every month to the first day of the month), and every hour (every 10:00 a.m.)] may be managed. The specific means by which the transmission information management means restricts the area to a portion of the area is not particularly important, and for example, a database listing areas that can be registered in the transmission information management means may be prepared and referenced when registering the transmission information, or the information for each reference point in the reference point database may further include an identifier of the available transmission information management means, so that when referencing a reference point, only transmission information management means that match the identifier can be referenced.

[0021] Furthermore, each of the transmission information management means can register the transmission information in the transmission information database only if the transmission information includes the transmission management identification information that is different from one another. By limiting the transmission information management means to different transmission management identification information, as illustrated in Fig. 4, the transmission information management means 13A-13C and the like can be divided into groups, and the transmission information can be registered separately by one or more registration terminals 6A-6C, and the transmission information management means 13A-13C can handle notification information in different fields individually, thereby eliminating congestion in the notification information field and making it easy to manage the registration of the transmission information.

[0022] Two or more sender management means may be provided, and the registered terminals that can use the transmission information management means corresponding to each sender management means may be limited based on the transmission management identification information. By limiting the registered terminals that can use the transmission information management means, the transmission information that can be used by the registered terminal and the transmission information of a specific user (for example, transmission information for in-house use of a specific company) can be identified by the transmission management identification information. In addition, the management of the transmission management identification information can be performed separately, making it easy to perform separate management for each field of notification information. The method of limiting the registered terminals can be selected arbitrarily, and for example, a database 17 listing each transmission information management means and the transmission management identification information of available registered terminals can be provided, and only registered terminals matching the transmission management identification information list database 17 can use the transmission information management means. Also, the transmission management identification information list database 17 can manage the registration of the transmission management identification information by the corresponding sender management means.

[0023] This message delivery system has multiple transmission information management means and sender management means, but if there is identifier information or the like to identify them, it is possible to have only one transmission information management means and one sender management means, and use the identifier information to obtain the same effects as when multiple transmission information management means and sender management means are provided.

[0024] This message delivery system can sequentially record the transmission information transmitted by the transmission information management means and the identification information of the user terminal to which the information is to be transmitted, and can perform any processing such as tallying up the results, statistical processing, etc. As an example, each of the transmission information management means can be provided with a transmission fee calculation means for calculating a usage fee by referring to the amount of notification information transmitted to the user terminal. The transmission fee calculation means is a means provided for each of the transmission information management means, and is a means for calculating a usage fee by referring to the amount of the notification information transmitted to the user terminal. The transmission amount is a quantity used to calculate the usage fee by combining one or more arbitrary amounts such as the number of transmissions to the user terminal, the number of days of use, and the transmission size. The transmission amount can be calculated by the notification information transmitting means together with the transmission of the notification information, and can be referred to by transmitting it to the transmission fee calculation means.

[0025] A more specific example of the message delivery system 1 shown in FIG. 1 will be described below. The notification information sending means 11, the transmission information management means 13, the sender management means 14, and the transmission fee calculation means 15, as well as the transmission information database 12 and the reference point database 16, which constitute this message delivery system 1, are configured as software executed on a server computer.

[0026] The user terminal 5, the registration terminal 6, and the management terminal 7 are connected to a notification information transmitting means 11, a transmission information managing means 13, and a sender managing means 14, respectively, by any communication means. The user terminal 5 is placed in a vehicle such as an automobile, and an application for connecting to the notification information transmitting means 11 is registered. The application transmits preset transmission management identification information and current location information consisting of latitude and longitude, etc., which are successively acquired, to the notification information transmitting means 11 as location information, and can display the notification information received from the notification information transmitting means 11 on the screen of the user terminal 5 and emit a notification sound. The displayed notification information includes text information about the current location (such as a summary of road information) and a URL link to a website where further details can be viewed.

[0027] 1. Notification information transmission means 11 Thereafter, message delivery by the notification information transmitting means 11 connected to the user terminal 5 is performed in the following procedure as shown in FIG. (1) The notification information transmitting means 11 receives location information acquired by a location information acquiring means (not shown) such as a GPS provided in the user terminal 5 (step S01). In addition, the received location information can be used as the previous location information the next time location information is received. (2) The notification information transmitting means 11, which has received the location information, refers to the reference point database 16 for a reference point corresponding to the received location information to determine the current area to which the information belongs (step S02). Also, it refers to the reference point database 16 for a reference point corresponding to the old location information, or uses the previous reference result to determine the old area to which the information belongs. (3) The current area is compared with the old area to calculate the movement direction, and movement direction information (traveling direction information) is obtained (step S03). (4) Destination area information whose moving direction and current area match, and transmission information that matches the separately received transmission management identification information, is obtained from the registrant management database (step S04). (5) When transmission information that matches the destination area information and the transmission management identification information is obtained, the notification information included in the obtained transmission information is transmitted to the user terminal 5 (step S05). (6) The user terminal 5 displays the transmitted notification information. (7) (1) and subsequent steps are repeated, and when a new area is reached, notification information is received.

[0028] 2. Transmission information management means 13 (1) When the message delivery system 1 is connected to a registration terminal 6, the transmission management identification information transmitted from the registration terminal 6 is received and the corresponding transmission information management means 13 is determined by the sender management means 14. (2) Next, the registration terminal 6 is connected to the determined transmission information management means 13, and the transmission information management means 13 performs registration processing of the transmission information. (3) The connected transmission information management means 13 receives the notification information, area and movement direction inputted and transmitted at the registration terminal 6, combines each received information with the transmission management identification information to generate transmission information, and registers it in the transmission information database 12. (4) After registering the transmission information in the transmission information database 12, the transmission information management means 13 detects whether the area and the moving direction of the currently connected user terminal 5 are the same as those of the transmission information. It is determined whether the area and the movement direction match, and if they match, the notification information included in the transmission information can be transmitted to the user terminal 5.

[0029] 3. Sender Management Methods14 The sender management means 14 stores a combination of the transmission management identification information and the corresponding transmission information management means 13. In addition, the sender management means 14 determines the transmission information management means 13 corresponding to the transmission management identification information sent from the transmission information management means 13 and sends it to the transmission information management means 13. Furthermore, the sender management means 14 can be connected to the management terminal 7, and can add or delete combinations of transmission management identification information and corresponding transmission information management means 13.

[0030] 4. Transmission fee calculation means 15 The transmission fee calculation means 15 prepares a history of the amount of notification information transmitted by the notification information transmission means 11 and the transmission management identification information corresponding to the notification information, and can calculate the usage fee as appropriate. The calculated usage fee can be notified to the user of the registration terminal 6 and / or the management terminal 7, and can be used to collect the fee for this system.

[0031] Incidentally, the present invention is not limited to the above-mentioned specific embodiments, and various modifications can be made within the scope of the present invention depending on the purpose and application. [Explanation of symbols]
