Description

The present invention, for registered members, determines the priority level of the group and divides them into groups, and then sets the distribution area based on the distance between the mobile terminal of the own terminal and another terminal, and selects the group, Alternatively, by group distributing information to the terminal group selected in the setting of the distribution area, or by setting the target number of distribution terminals, the group selection is prioritized according to the priority order, or close to the own terminal. The present invention relates to a system and method for grouping terminals by determining a terminal group according to whether or not the distribution area setting is prioritized farther away.

Conventionally, when a danger is encountered, the danger information is distributed to pre-registered family members. If you try to increase the number of registered members, it is more likely that stalker is included. If included, the distributed danger information will attract the stalker who is a registered member.

Patent Document 1 is cited as a danger information notification system related to the present invention using a mobile terminal. In Patent Document 1, in a distributed communication network, position information is acquired by GPS, distance is calculated, and a terminal group to be a distribution partner is selected. Then, the emergency danger information is continuously delivered to the selected terminal group. However, it is possible that a potential stalker has been selected as the distribution partner.

Japanese Patent No. 6106352

The conventional danger notification system sends danger information or requests rescue to a pre-registered notification destination when the notified person falls into an emergency or an emergency. If you try to increase the number of registered members so that many people will come to the rescue, the possibility that stalker is potentially included will increase. In other words, if the dangerous information is distributed, it may attract the stalker. Then, this invention makes it a subject to protect the said notifier himself by delivering by removing the stalker.

Regarding the method of solving the former problem, the present inventor regards registered members as "family (associating with A group)" and "friends (associating with B group)", "educational institution, company, various groups (with C group). Yes)”, “App registered members (D group)”, and the distribution method is added according to the priority level according to the notification person's risk level. I found a technique. Personal information can be specified by affiliated organizations such as educational institutions, public organizations, companies, and various organizations, so even if it is delivered, it is less likely to attract potential stalker, and a safer danger notification system Can be built. The inventors have found a solution to such a problem and completed the present invention.

The present invention comprises a group distribution system and method.

In order to solve the above-mentioned problems, a group distribution system of the present invention is a group distribution system in which a self terminal distributes to a mobile terminal group, and the mobile terminal group is grouped according to priority order. A distance calculating means for calculating the distance between the own terminal and another terminal by GPS; a distribution area setting means for setting a distribution area by the distance between the own terminal and another terminal; and the group according to the priority order. Selecting group selecting means, using the distribution area setting means and the group selecting means, selecting another terminal from the selected distribution area and group, the terminal selecting means, and the terminal selected by the terminal selecting means And an information distribution means for distributing information to another terminal.

Further, the group distribution method of the present invention is a group distribution method in which the terminal distributes to a group of mobile terminals, the grouping step of grouping the group of mobile terminals according to priority order, the group of terminals and others. A distance calculation step of calculating a distance between terminals by GPS, a distribution area setting step of setting a distribution area based on a distance between the own terminal and another terminal, and a group selection step of selecting the group according to the priority order. And selecting another terminal from the selected distribution area and group using the distribution area setting step and the group selection step, and distributing information to the terminal selection step and the other terminal selected by the terminal selection step. And an information distribution step.

The present invention, by setting the distribution area by the distance between the own terminal and another terminal for the mobile terminal group grouped by priority order, and by selecting the group according to the priority order, It adopts a method of selecting other terminals from the distribution area and group that were finally selected. With this method, the possibility of encountering a potential stalker is reduced, and the notifier having the own terminal can be protected safely.

It is a figure showing an example of a terminal group database of a plurality of virtual self-terminals built in a management server.

Next, an embodiment of the present invention will be described with reference to the drawings. However, the distribution group to be described below has a mobile terminal and is registered in the terminal group database (see, for example, FIG. 3), and the terminal group is under the environment of a normal network and a wireless ad hoc network via a base station or a wireless access point. Imagine that you can communicate in groups.

Regarding the distribution group, in the first to fourth embodiments described later, such as "family" who wants to be delivered at all times regardless of the danger level of the notification person, and "friends" who wants to deliver a rescue call when they are nearby, It is divided into four groups: A group (family), B group (friends), C group (educational institutes/companies/organizations), and D group (application registered members), and priority is given from A (high) to D (low). Assume that they are ranked. In the example of the terminal group database, the first digit of the terminal ID is used for grouping in this case, and letters A, B, C, and D are given to each group. In the fifth embodiment, the usage charge is divided into three groups of gold, silver, and no distribution.

FIG. 1 is a functional comparison diagram of distribution methods 1 to 5 for group distribution according to the present invention. From the four viewpoints of the items "presence/absence of target terminal number setting", "operation of group and distribution area", "different distribution information", and "contents of distribution information", the following five distribution methods are classified.

<When the target number of distribution terminals is not set>
Distribution method 1: A distribution area is fixed, and different information is distributed to high and low priority groups.
Delivery method 2: A delivery area is set for each high-low priority group and the same information is delivered.
<When setting the target number of distribution terminals (Distribute the same information)>
Delivery method 3: Prioritize the selection of groups in order of priority, increase or decrease the delivery area in the same priority group, and select the target number of terminals.
Delivery method 4: Prioritize the delivery area setting from near to far from the own terminal, add groups in the same delivery area in order of priority, and select the target number of terminals.
As described above, the distribution methods 1 and 2 and the distribution methods 3 and 4 are roughly classified according to whether or not the target number of distribution terminals is set.

Delivery method 5: A delivery area is set for each high-low priority group, and different information is delivered. The target number of distribution terminals has not been set. That is, the features of both delivery methods 1 and 2 are adopted.

Note that the delivery terminals 3 and 4 need to set the delivery terminal target number in order to secure a certain number of rescuers when the notification person encounters a danger.

Hereinafter, the contents to be distributed by the distribution methods 1 to 4 will be referred to as “danger information”, which will be described in the first to fourth embodiments, respectively. After that, as an application of the distribution method 5, the contents to be distributed are “facility conditions, event information, etc.”, and a distribution example in a theme park will be described in a fifth embodiment.

The description is based on the first and second embodiments. In the first form, the distribution area is fixed and the distribution information is changed for each of the high and low priority groups. In form 2, the distribution area to which the information arrives is changed for each of the high and low priority groups. However, the distribution information is the same. The explanatory views of Embodiments 1 and 2 are FIGS. 2 and 3, and FIGS. 4 and 5, respectively.

In the first and second embodiments, the delivery terminal target number is not set.

<Embodiment 1>
Fix the distribution area and distribute the information to all registered members in the area. However, all the obtained information is distributed to the highest group, but the quality of the information is deteriorated and distributed to the lower groups. In this way, the form 1 is intended to distribute the gradually decreasing information for each group.

The form 1 will be described with reference to FIG. This figure is a conceptual diagram for distributing different information for each group within the same distribution area. The priority order is lowered in order from the A group, and the D group is the lowest priority group. The number of people in group A is 3, the number in group B is 10, the number in group C is 20, and the number in group D is 30. These numbers are also the numbers used in FIGS. 2 to 10 except FIG. 8.

In FIG. 2, the distribution area is fixed at a radius of 50 km. As shown by the shaded area, the number of people entering the distribution area is 2 for the highest A group, 8 for the upper B group, 6 for the lower C group, and 20 for the lowest D group. is there.

Here, the distribution area refers to an area centered on the notifier (self-terminal), which can be rushed to when there is a rescue call from the notifier. If you use a car, the distance within 30 minutes is within 50 km.

Delivery information varies by group. Information in the distribution area of FIG. 2, that is, the highest information for group A, the highest information for group B, the lowest information for group C, and the lowest information for group D are provided. For example, all dangerous information including the notification person's surrounding image is included in the group A, the notification person's movement route information is included in the group B, only the notification person's location information is included in the group C, and the information is not distributed to the group D. It is possible to distinguish the distribution information.

In this way, by distributing different information according to priority order, it is possible to reduce the psychological burden of the recipient who has to go to help. Although it is divided into subordinate groups, if you really want to go to the rescue, there is less information to be delivered in the subordinates, so you have to ask a friend by phone and acquire the information by another means.

FIG. 3 is a diagram showing an example of a terminal group database when different information is distributed for each group. The lower the group from the D group (application registered member) 34 to the A group (family) 31, the higher the priority. These prioritizations are the same as the prioritization used in FIGS. 4 to 10 except for FIG.

The item "distance flag" 72 in the figure is used to select a mobile terminal within the distribution area. First, the number of distances between the notifier (self terminal) and another terminal group is obtained from the position information GPS of the terminal group. Next, the distribution area 20 (see FIG. 2), for example, 50 km is compared. Then, the distance flag 72 of the mobile terminal group within the radius of 50 km is turned on (1). Next, different information for each group is distributed to the terminals that are ON (1).

When selecting a distribution terminal, if the notifier distributes the dangerous information to the other terminal group at regular intervals, most of the registered members are likely to move. Therefore, the position information is regularly confirmed. Before distribution, the number of distances between the notifier (self terminal) and the other terminal group is sequentially obtained, and the distance flag 72 is turned ON (1)/OFF (0) by comparison with the distribution distance.

It should be noted that, in the future, the distribution area code will be properly used as 20a (minimum), 20b (midway), and 20c (maximum), but the distribution areas will be collectively referred to as the distribution area 20.

<Embodiment 2>
The idea of the second embodiment is that a group having a high priority should rush to rescue people at a long distance. If the priority is low, it will be painful to get help in a long distance. It does not deliver to the lowest group, as it does not ask for help. This is in consideration of the notifier's feeling.

In the second embodiment, the target number of distribution terminals is not set as in the first embodiment. The difference is that there are a plurality of distances for setting distribution areas for each of the high and low priority groups. The information delivered to the selected terminals is the same.

FIG. 4 is a conceptual diagram in which the same information is distributed for each group in different distribution areas. There are a plurality of distances for setting the distribution area for each high-low priority group. In the case of the figure, the number of distances from the highest group A to the lowest group D is 70 km, 60 km, 50 km, and 0 km for setting the distribution area.

In the figure (a), since the terminals of the group A are compared with 70 km, they are distributed to all three persons. In the same figure (b), the terminals of the group B are delivered to 8 out of 10 people for comparison with 60 km. In the same figure (c), the terminals of the group C are distributed to 4 out of 20 people for comparison with 50 km. The terminals in the D group are compared with 0 km and are not delivered to any of them. However, the shaded area is a terminal that can be distributed, and the number of people is also shown in the shaded area.

FIG. 5 is a diagram showing an example of a terminal group database when the same information is distributed for each group. The item "distance flag" 72 in the figure is used to select a mobile terminal within the distribution area. The "distance number" 73 allows a plurality of distance numbers to exist for each group. Specifically, as shown in the figure, the numerical values of 0, 50, 60, and 70 are set from the upper side in this item.

First, the number of distances between the notifier's own terminal and another terminal group is obtained from the position information GPS of the terminal group. Next, each group is compared with each numerical value of the item "distance number". Then, the distance flag 72 of the mobile terminal group is turned ON (1). Next, the same information is distributed to the terminals that are ON (1). The location information of each terminal group is regularly confirmed.

The ideas of the third and fourth embodiments will be described in order using a case of commercial transaction.

The salesperson has a quota (the target number is set) for product sales as the fiscal year approaches. I would like to give priority to the product information to the good customer group (A) having a high priority as far as possible (in the range of the distribution area) even if they are far away. The level of interest in the product is gradually decreasing in the customer group (B→C→D), and even if the information is transmitted to the customer group (D) who does not move their finger when the information is transmitted, it is useless. Do not convey information. In other words, the idea is to select customers who convey product information in descending order of priority.

Next, think from the standpoint of the seller who gives the highest priority to freshness. I bought a lot of fresh food with high freshness. I want to sell out today (set target number). Since the freshness was the game, I first sold it to customers in the neighborhood (minimum distribution area), but it remained. So I went to a distant place (enlarged distribution area), but I went out and sold to a good customer group (A) who always buys, but it still remained. This is the position of a business-enthusiastic person who sells to the customer group (B) who will buy next. In other words, the idea is to sell from nearby customers without going far.

Therefore, Embodiment 3 is prepared to realize the former parable, and Embodiment 4 is prepared to realize the latter parable. In each of the third and fourth embodiments, the selection of groups is prioritized, the distribution area is increased/decreased in the same priority group to select the target number of terminals (distribution method 3), and the distribution is performed from near the terminal to far This is an embodiment of a system (distribution system 4) in which area setting is prioritized, groups are added in the same distribution area in order of priority, and a target number of terminals are selected.

In the third and fourth embodiments, the target number of distribution terminals is set. This setting of the target number of terminals is intended to secure a certain number of rescuers when the notifier encounters a danger. It is assumed that the target number of distribution terminals that can communicate in the distribution area is set to 30 people.

In addition, in these modes, the incremental distance per step of increasing the distribution area is set to 10 km. In addition, an area within a radius of 50 km surrounded by a dotted line that can be reached within 30 minutes by car is defined as the minimum distribution area 20a.

Next, description will be made in the order of distribution method 3 (FIGS. 6 to 8) that prioritizes group selection and distribution method 4 (FIGS. 9 to 11) that prioritizes distribution area settings from near to far from the terminal. To do.

<Embodiment 3>
This is an embodiment based on the idea that, when the notifier encounters danger, he/she wants a high-priority group such as a family member or a friend to rush as far as possible (within the range of the distribution area).

6 to 8 show an embodiment in which the distribution terminal target number is reached in the distribution format 3 in which the selection of groups is prioritized in the order of priority. First, FIG. 6 is a conceptual diagram in which group selection is prioritized. (A) shows that A group is selected, (b) shows A and B groups are selected, and (c) shows that A, B, and C groups are selected. In these figures, the selected group is indicated by the shaded area.

In FIG. 6A, first, the highest-order group 31 of A is specified by the group selection means. Next, the distribution distance is gradually increased by 10 km from the minimum distribution area 20a (dotted line area in FIG. 9A) to the maximum distribution area, and the number of distribution terminals is calculated each time. 20c (solid line area in FIG. 10A) with a radius of 70 km, and finally three people. Here, the distribution area having a radius of 70 km surrounded by the solid line is set as the maximum distribution area 20c. In other words, the number of distribution terminals is calculated up to the maximum range of the distribution area, and the number of terminals exceeding that range cannot be counted.

Since the above three people do not reach the target number of distribution terminals of 30, the group B is added in FIG. 6B, and the distribution areas are gradually increased as groups A and B as in FIG. 6A. As a result, the total number of distribution terminals is 13.

Since the target number of distribution terminals is still less than 30, the group C is further added in FIG. 6C. Although the distribution area is gradually increased from the minimum distribution area, in the same group, the maximum distribution area 20c has 18 distribution terminals, which is 31 in total. This means that the distribution terminal target number of 30 has been reached.

The contents of the terminal group database in the distribution area (radius 70 km) in FIGS. 6A, 6B, and 6C correspond to FIGS. 7A, 7B, and 7C, respectively.

The item “G selection (hereinafter, referred to as G selection flag)” 70 in FIG. 7A is ON (1) when a group is selected. Therefore, in the figure (a) in which only the A group (family) 31 is selected, the G selection flag 70 of the A group is ON (1), the B group (friend) 32, the C group (educational institution, company, Since the group 33 and the D group (application registered member) 34 are not selected, the flag 70 is set to OFF (0).

The mobile terminal in the distribution area is determined as follows. First, the number of distances between the notifier (own terminal) and another terminal group is obtained. Next, a comparison is made with the distribution area 20c, for example, 70 km. Then, the distance flag 72 of the mobile terminal group within the radius of 70 km is turned on (1).

When the distance flag 72 is obtained, the selection flag 71 is turned on (1) by a logical product (AND) with the G selection flag 70. Therefore, when delivering the danger information, the delivery is performed to the registered members whose selection flag 71 is ON. In FIG. 7A, the number of ON selection flags 71 (the number of distribution terminals) is three.

Since the target number of distribution terminals is less than 30, the G selection flag 70 of the B group is added to ON (1) in FIG. 7B, and the ON number of the selection flag 71 is obtained. There are 13 people.

Since it is not satisfied yet, in FIG. 7C, the G selection flag 70 of the C group is further turned ON (1) to be added, and the ON number of the selection flag 71 is obtained. It shows that it has become 31 people. The location information of each terminal group is regularly confirmed.

FIG. 8 is a flow chart for determining a distribution terminal group with group selection priority. First, priority is given to groups such as "family", "friends", "educational institution/company/group", and "application registered member" (step S11).

In specifying the group when the application is activated (step S12), the highest-level group is selected. Next, the minimum distribution area is set (step S13), and the number of distribution terminals is calculated in the distribution area at that time. This number is the total number of ON of the selection flags 71 of the terminal group database (FIG. 7). The number is used to determine whether the target number of distribution terminals has been reached. If not reached (NO in step S14), the distribution area is increased by one step (step S15).

It is confirmed whether or not the maximum distribution area is exceeded, and if not exceeded (NO in step S16), the process returns to step S14. If the target number of distribution terminals has been reached (YES in step S14), distribution terminals are determined (step S18). If it has not reached (NO in step S14), the distribution area is further increased by one step (step S15). When the maximum distribution area is exceeded (YES in step S16), the priority order is lowered by one and a priority group is further added (step S17), the minimum distribution area is set again (step S13), and steps S13 to S17 are performed. Repeat the operation.

<Embodiment 4>
This is an embodiment based on the idea that a person who can rush to the rescue by setting the minimum distribution area from the notifier should come as soon as possible, rather than uncertainty about his/her identity. Similar to the third embodiment, the target number of distribution terminals is set to 30 people.

9 to 11 show an embodiment in which the delivery terminal target number is reached in the delivery format 4 which prioritizes the delivery area setting from near to far from the own terminal. First, FIG. 9 is a conceptual diagram in which distribution area setting is prioritized. Group (a) is selected by group A, B, group (b) is selected by group A, B, C, group (c) is selected by group A, B, C, and the distribution distance of each is 50 km. In (d), groups A, B, C, and D are selected, and the distribution distance is 60 km. In these figures, the selected group is indicated by the shaded area. Then, the distribution terminals in the distribution area are distinguished by the cross hatched portion.

First, the distribution area setting means sets the minimum distribution area 20a (radius 50 km). Next, groups are sequentially added from the highest group to the lowest priority group, and the number of distribution terminals is calculated each time. In the groups A and B of FIG. 9A, there are four people.

Since the target number of distribution terminals is less than 30, the group C is added in FIG. 9B, and distribution terminals within the distribution area are obtained as groups A, B, and C. As a result, the total number of distribution terminals becomes eight.

Since the target number of distribution terminals is still less than 30, the lowest D group is added in FIG. 9C. The total number of distribution terminals in the distribution area is 18.

Since the target number of distribution terminals is less than 30 even if the lowest D group is added, the distribution area is increased by one step in FIG. 9D.

When groups are sequentially added to the A, B, C, and D groups in the expanded distribution area 20b, the total number of distribution terminals in the distribution area becomes 36. This means that the distribution terminal target number of 30 has been reached. However, if the number of distribution terminals does not reach the target number of distribution terminals even if the maximum distribution area 20c is exceeded, the number of terminals at that time is used for determination (see the annotation of FIG. 1).

The contents of the terminal group database with a distribution distance of 50 km in FIGS. 9A, 9B, and 9C correspond to FIGS. 10A, 10B, and 10C, respectively. The content of the distribution distance of 60 km in FIG. 9D is shown in FIG.

The G selection flag 70 of FIG. 10 is turned ON (1) when a group is selected. A group B is selected in (a), A group, B group and C group are selected in (b), and A group, B group, C group, and D group are selected in both (c) and (d). Therefore, the G selection flag 70 corresponding to each is ON (1).

The selection flag 71 is turned on (1) by the logical product (AND) of the distance flag 72 and the G selection flag 70. In FIG. 10A, the number of ON selection flags 71 (the number of distribution terminals) is four.

Since the target number of distribution terminals is less than 30, the G selection flag 70 of the C group is turned ON (1) and added in FIG. 10B, and the ON number of the selection flag 71 is obtained. There are 8 people.

Since it has not been satisfied yet, in FIG. 10C, the G selection flag 70 of the D group is further turned ON (1) and added, and the ON number of the selection flag 71 is obtained. It shows that the number of people has increased to 18.

Even if the lowest D group is added, it is not enough, so the distribution area is increased by one step. When the final number of ONs of the selection flag 71 of FIG. 10(d), which is obtained by sequentially adding the groups A, B, C, and D, is obtained, it indicates that the number of people has finally reached 36. Note that, similarly to the modes 1 to 3, the position information of each terminal group is regularly confirmed.

FIG. 11 is a flow chart for deciding a distribution terminal group by giving priority to distribution area setting. The step of S21 is the same as S11.

In the setting of the distribution area when the application is activated, the minimum distribution area is set (step S22). Next, the uppermost group is specified (step S23), and the number of distribution terminals is calculated in the distribution area at this point. This number is the total number of ON of the selection flags 71 of the terminal group database (FIG. 10). The number is used to determine whether the target number of distribution terminals has been reached. If not reached (NO in step S24), the priority is lowered by one and a priority group is further added (step S25).

It is confirmed whether or not the lowest group has been added, and if not added (NO in step S26), the process returns to S24. If the target number of distribution terminals is reached (YES in step S24), the distribution terminal is determined (step S28). If not reached (NO in step S24), the priority order is lowered by one and a priority group is further added (step S25). If the lowest group is reached (YES in step S26), the distribution area is increased by one step (step S27), the highest group is specified again (step S23), and the operations from S23 to S27 are repeated.

Here, looking at the creditworthiness of the registered members, generally, the A group (family) 31 and the B group (friend) 32 are the notified persons with a solid identity. A C group (educational institution/company/organization) 33 and a D group (application registered member) 34 are added as distribution groups to these groups as registered members. This means that the creditworthiness of all members is reduced. If you are worried about a decline in creditworthiness, do not select the lowest D group (application registered member). If only the C group (educational institution/company/organization) 33 is added to the group, the personal information is specified, so that the anxiety of uncertainty about the identity can be removed. However, in this case, if the target number of distribution terminals is set to be large, there may be a situation where the number of distribution terminals does not reach (see the annotation in FIG. 1).

Now, in order to distribute the danger information, the terminal group database as shown in FIGS. 3 and 5 is placed in the mobile terminal main body of each registered member. However, for ease of management, the terminal group database of all the registered members can be placed in the management server. In either case, the terminal IDs of other terminals in the individual terminal group database of registered members differ for each registered member.

<Embodiment 5>
The fifth embodiment is a development of the ideas of the first and second embodiments of the present invention. A plurality of notifiers (self-terminals) that do not move still are placed at different positions, and a terminal group database corresponding to the different positions is present on the management server. That is, a plurality of pieces of position information of a plurality of notifiers (own terminals) are prepared, and a terminal group database for the plurality of notifiers (own terminals) is provided in the management server.

Since the terminal group databases for the plurality of notifiers (self terminals) are the same except that the positions of the notifiers (self terminals) are different, the attribute information of the other terminals is different between the plurality of notifiers (self terminals). Is common in. However, the attribute information includes the terminal ID and grouping information.

As a procedure, at the same time as member registration, the other terminals are divided into groups. Since the position information of a plurality of notifiers (own terminals) exists in the management server, GPS information from users (other terminals) is sent to the management server. Next, the distance between the own terminal and the other terminal is calculated, whether or not the terminal is in the distribution area is confirmed, and group-specific information distribution to other terminals in the distribution area is performed. These operations will be executed by the management server.

From the above idea and procedure, an application as shown in FIG. 12 is produced. The figure is a diagram showing a distribution area example (a) and a display example (b) of information to be distributed, centering on a plurality of virtual own terminals (hereinafter referred to as virtual distribution spots). The same figure (a) shows a plurality of distribution areas 20a and 20b of a theme park, and the figure (b) is a display example of different information for distribution areas 20a and 20b distributed from P1 spot.

FIG. 1A shows a virtual distribution spot in the theme park, that is, a virtual information center. Within the theme park, multiple distribution spots (P1 to P5) that can transmit various information will be provided. The position of the location can be changed according to the operation status of the theme park.

When entering the distribution area centered on the distribution spot, information such as the degree of attraction, restaurant congestion, and events is provided to the mobile terminal of the user (other terminal). Not only can you provide information, but you can also apply for a numbered ticket for admission to a distant attraction on the site from the mobile terminal of the recipient while you are in a distant place.

Information will not be delivered if it is far from the delivery spot, so it will be possible to deliver it if you pay a higher usage fee. As shown in FIG. 12B, in the distribution area 20a (for example, a distribution distance of 100 m), only the silver information can be obtained, but if a higher usage fee is paid, the distribution area 20b is expanded and the gold information is also acquired. Will be obtained. Here, the grouping of the distribution areas 20a and 20b is determined by the level of usage charge.

FIG. 13 is a diagram showing a terminal group database example of a plurality of virtual own terminals, which is built in the management server. In order to allow a plurality of virtual distribution spots to exist, five terminal group databases linked to the P1 to P5 spots are constructed. The registered terminal ID and grouping information are repeatedly input to the individual terminal group database five times. The distribution procedure is to calculate the distance between other terminals from the five virtual distribution spots by the GPS difference, compare the distribution distances 100m and 200m set for each distribution spot, and calculate the distribution area 20a or distribution area. If it is within the distribution area of 20b, the distance flag is turned ON (1). Then, the silver or gold information is distributed for each group.

For example, referring to the database at the P1 spot in FIG. 13, the distance flag of the terminal with the terminal ID C001 is ON (1). In this case, the silver information of FIG. 12B is distributed to the terminal C001.

The groups in FIG. 12 and FIG. 13 are divided according to the level of usage fee payment. However, in FIG. 13, people who have not paid the usage fee are also registered members. In the figure, since the distance flag is OFF (0) as compared with the distribution distance of 0 m, distribution is not performed. However, generally, if you do not pay the fee, you will not become a registered member. Broadly interpreted, those who do not pay the usage fee can be regarded as the lowest priority group below the registered members.

According to the idea of the delivery method 5 as shown in FIG. 12, it is possible to provide a plurality of delivery spots in a wide space such as a park where no amusement facility exists. A simple theme park by devising ways such as when the user (another terminal) enters the distribution area that draws the distribution spot and hears the sound from the smartphone, or the CG is displayed on the smartphone. Can be transformed into

In addition, as areas for people to move, areas in museums and museums where audio guides for exhibits are used, highway areas that enable early acquisition of signpost information, and sea areas that provide appropriate fishing point information It can also be applied in areas.

Lastly, the terminal group database of Embodiments 1 to 4 can be placed in the body of the own terminal of the notifier or in the management server as shown in FIG. However, in this case, the terminal IDs registered in the five notifiers (own terminals) P1 to P5 are different for each terminal group database for each notifier (own terminal). Whether the terminal group database should be placed on the mobile unit or the management server, but since a large amount of power is consumed by reading the GPS, the current technology is to place it on the management server, including ease of management. Seems to be good.

When placed on the management server, the current position of the terminal is measured by GPS and the position information is transmitted to the management server. Subsequent operations, such as grouping other terminal groups, selecting a group according to the priority order, confirming whether it is within the distribution area, etc., are performed by the management server. That is, most of the distribution processing is performed by the management server.

By making the first to fourth embodiments as described above, it is possible to make the invention more secure when the notifier encounters a danger.
