Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same reference numerals are given to the same components, and the description will be omitted as appropriate.

[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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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).

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.

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.

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.

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. .

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.

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.

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.

[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.

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.

FIG. 6 is a flowchart showing the information processing method of this embodiment. The operations in steps T1 to T8 are the same as those in steps S1 to S8 described in the first embodiment. Further, the operations from step T9 to step T11 are the same as the operations from step S9 to step S11 described in the first embodiment.

When the synchronization request signal for synchronizing the positioning process for generating the position information is not transmitted to each of the mobile terminal indicated by the new identification information and the mobile terminal indicated by the identification information output in step T7 (step (NO in T12), a synchronization request signal is transmitted to the mobile terminal (step T13). After step T13, the process proceeds to step T1.

On the other hand, when the synchronization request signal has been transmitted to the mobile terminal (YES in step T12), the mobile terminal transmits content readable by the mobile terminal (step T8). After step T8, the process proceeds to step T9.

Here, the effect of this embodiment will be described. In this embodiment, a synchronization request signal is transmitted to the mobile terminals searched as the same group, and the timing of the positioning process of the mobile terminal is synchronized. If the search process is executed again using the received new position information and new identification information after synchronizing the positioning process, the search process with higher accuracy can be performed.

In addition, since the positioning process of the mobile terminal to be searched is synchronized, even when the mobile terminal is moving at high speed, it is possible to perform a search process with relatively high accuracy.

As described above, the embodiments of the present invention have been described with reference to the drawings. However, these are exemplifications of the present invention, and various configurations other than the above can be adopted.

The present invention can be applied to the use of an information providing system that provides information in accordance with a user's situation based on position information intermittently transmitted from a mobile terminal carried by the user. In particular, it is suitable for an information providing system that searches for another mobile terminal (accompanied person) who travels on the same travel route as that of one mobile terminal and provides information according to the situation. In general, since the presence or absence of a companion greatly affects the user's situation, the present invention can be used effectively.

In addition, the location information and identification information transmitted from the mobile terminal carried by the user, and the location information and identification information transmitted from the car navigation device mounted on the vehicle driven by the user are combined to determine which usage the vehicle uses. It is also applicable to uses such as determining whether a person is on board. In general, a plurality of users often board a car, and the present invention can be effectively utilized when providing information reflecting the passenger's preference to a car navigation device.

On the other hand, in the above embodiment, the system including the content transmission unit 26 as a component has been described, but the present invention is not necessarily used for content distribution. The present invention repeatedly receives position information and identification information from each of a plurality of mobile terminals, and searches for mobile terminals in a positional relationship that satisfy a specific condition based on the received position information and identification information. If so, it is applicable.

In the description of the above embodiment, a plurality of flowcharts are used, and a plurality of steps are described in order. The order of description is the order in which the steps of the information processing method of the present invention are executed. It is not intended to limit. For this reason, when the information processing method of the present invention is executed, the order of the plurality of steps can be changed within a range that does not hinder the contents.

This application claims priority based on Japanese Patent Application No. 2010-56952 filed on Mar. 15, 2010, the entire disclosure of which is incorporated herein.
